Vehicle Maintenance

What is the break-in period of my Acura?
Help assure your vehicle's future reliability and performance by paying extra attention to how you drive during the first 600 miles (1,000 kilometers). During this period:
  • Avoid full-throttle starts and rapid acceleration.
  • Avoid hard braking. New brakes need to be broken in by moderate use for the first 200 miles (300 km).
Can I have my maintenance services performed by anyone I choose?
Our authorized dealers know your vehicle inside and out, and can provide competent, efficient service. However, service at a dealer is not required to keep your warranties in effect. You may service your car with any qualified service facility or person. Just be sure to keep all receipts as proof of completion, and have the service technician fill out the Maintenance Record. Refer to your warranty booklet for more information.

Many after-market repair services, such as the mass-marketers (chain stores), hire poorly-trained people to work on your high-technology vehicle. Generally speaking, their Acura product knowledge is minimal.

Some ex-dealership technicians open their own independent shops and specialize in that brand of vehicle. However, their "factory" training is usually several years old, so their technical knowledge of current model vehicles will not be as good as the local dealer's technicians, who routinely receive new model training from American Acura.

Acura parts and fluids are manufactured to the same high-quality standards as the original components, and we recommend the use of them every time you have maintenance performed.

If I choose to have my maintenance services performed by someone other than an Acura dealer, must I keep records?
It's always a good idea to keep records of all services and repairs of your vehicle. The Service Records feature here on Acura Owners Site is a handy way to keep track of each service visit.

An Acura dealer’s computer system automatically does this for you, as it maintains Vehicle Service History records electronically. A dealer can review any and all work performed by that store.

I'm leasing my vehicle. Why should I worry about servicing my Acura?
There are two very good reasons why you should maintain your vehicle according to the schedule in your Owner's Manual.

Regularly maintaining your car is the best way to protect your investment. Proper maintenance is essential to your safety and the safety of your passengers. It will also reward you with more economical, trouble-free driving and help reduce air pollution.

Vehicle condition is evaluated at the end of the lease period and you will be charged for abnormal conditions that reduce the value of the vehicle. This includes mechanical condition.

My "Malfunction Indicator Lamp" stays on while I'm driving. What should I do?
Typically, this indicator displays for several seconds when you turn the ignition switch ON.

If you have recently refueled your Acura, this light may display to warn you of a loose or missing fuel filler cap. Check the cap and tighten it until it clicks. If the fuel cap is missing, replace it with a Genuine Acura replacement cap. Tightening the cap will not make the indicator turn off immediately; it may take several driving trips.

If the indicator continues to display after three driving trips, or if the fuel cap was not loose or missing, there may be a problem in one of the engine's emissions control systems. You should have the vehicle checked by the dealer as soon as possible.

You should also have the dealer inspect your vehicle if this indicator comes on repeatedly, even if it turns off as you continue driving.

How often do I need to change the timing belt on my vehicle?
Depending on the model year of the vehicle, it is typically between 60,000 and 90,000 miles. If your vehicle has a timing chain, instead of a timing belt, replacement of the timing chain is not required. Refer to the Scheduled Maintenance section of the appropriate owner's manual for specific information.
Is it normal for my headlights to dim slightly and then come back to normal while my car is stopped at a light?
This is a normal characteristic and is caused by variations in the electrical system created by the onboard computer. The computer controls the output of the electrical charging system to improve fuel economy and minimize vehicle vibration.

While the engine is at idle, the computer monitors the electrical usage of the car and then controls the electrical charging system so that it charges just enough to keep up with demand. This change reduces the load on the engine and, in turn, increases fuel economy and reduces vehicle vibration. As electrical accessories turn on and off, the computer changes the rate of electrical charge in response to the changes in demand for electricity. As the computer responds to the addition of electrical load, you may notice a momentary dimming of the lights. For example, the headlights or instrument panel lights may briefly dim as the air conditioning cycles on.

Why do my HID headlights appear uneven or out of adjustment?
The Acura models with high-intensity discharge (HID) headlights use a different beam pattern than what’s found on vehicles with conventional headlights. The top edge of each headlight beam is cut off lower on the left side, and rises toward the right side. For this reason, when the headlights are turned on, the beam pattern can appear uneven from the far left edge to the far right edge, especially when you’re closely following another vehicle or shining the headlights on a nearby wall. This apparent unevenness in the headlight beams is a normal characteristic and not something to be concerned about. Although the actual beam patterns may vary between models, a typical beam pattern found on HID-equipped Acura models has these features:
  • Left Side: Shines lower to avoid blinding drivers of oncoming vehicles.
  • Right Side: Shines higher to provide good illumination of road signs and to illuminate pedestrians.
  • Center: Shines below the rear window of passenger vehicles you’re following.

HID Beam Headlights

How can I find out if my vehicle is affected by a campaign?
There are a number of ways to find out if your vehicle is affected by a campaign (recall, product update, or extended warranty). You can access information on any campaign affecting your vehicle by clicking here or call Acura Client Relations at (800) 382-2238 (press the appropriate option for Campaign information).
When I look through the side of the windshield on my car, it's all wavy and distorted. Is this normal?
This distortion is called "cross-car distortion." You will notice it when you're watching a vehicle cross in front of your car and also when you're turning left and looking through the right side of the windshield at other vehicles. Front-seat passengers see the same distortion when they look through the left side of the windshield. Since cross-car distortion occurs when you look through the glass at an angle, it may be even more noticeable for short drivers. Wearing nonprescription sunglasses, which tend to reduce depth perception, also may increase the perceived distortion.

Some cross-car distortion exists in the windshields of Acura vehicles manufactured since 1994. In fact, all of these recent Acura windshields have this distortion to some degree, and the condition should be considered normal. Because the aerodynamic windshield of recent Acuras is at more of an angle than in the past, the cross-car distortion may be slightly more noticeable, even though the jump distortion is at the same low level as before. These windshields meet all applicable Federal Motor Vehicle Safety Standards for glazing materials, and this minor distortion is allowable within the industry specifications for automotive glass.

The BATTERY CHARGE LOW or BATT LOW warning message on my dash is on. What does that mean and what should I do?
For vehicles equipped with the Battery Management System, this message occurs when the battery’s State of Charge has dropped below a predetermined level. The message is intended to inform you that the battery requires charging to guarantee proper performance under all conditions (extremely cold conditions, high electrical system demands, etc).

Conditions that may cause the battery charge to drop enough to prompt the BATTERY CHARGE LOW or BATT LOW message are:

  • Extended time spent with the ignition on, but the engine not running. The affect on the battery is made worse if the radio, lights, heater fan or other accessories are on at the same time.
  • Driving short trips repeatedly without a longer trip between them. The starter uses a lot of energy when starting the engine. If the engine is not run long enough, the charging system cannot recharge the battery to the level it was at before the engine was started. Running high-demand electrical accessories, such as seat heaters, can make this situation even worse.
  • Extremely cold weather is also hard on the battery. Not only does it require more energy to start the vehicle in the cold, but the battery just doesn’t work as well.

If any of these conditions occur, and the battery charge drops below a certain level, the battery management system informs the driver that the battery may not be able to start the vehicle in extreme cases by illuminating the BATTERY CHARGE LOW or BATT LOW warning message. While this message does mean the battery charge is low, it usually does not mean that the battery won’t start the engine.

If you see the BATTERY CHARGE LOW or BATT LOW message, don’t panic. It simply means the battery charge is lower than it should be. This can be fixed by taking longer trips between shorter trips, minimizing unnecessary electrical accessory usage during short trips, and spending less time using electrical accessories while the engine is not running.

The battery management system is intended to protect the driver from allowing the battery charge to drop to a point where it cannot start the vehicle. By using it as a guide, not only will the life of the battery be extended, but the chances of the vehicle not starting due to a discharged battery will be greatly reduced.

Is it possible to tow my Acura vehicle with all four wheels on the ground (dinghy towing)?
For model year 2006 and newer, if an Acura vehicle is approved for towing with all four wheels on the ground, it will be noted in the Owner’s Manual for that vehicle. Please refer to the Owner's Manual for specific towing instructions.

For model year 2005 and older, dinghy towing capability may or may not be possible. Please contact Acura Client Relations (800-382-2238) for additional information on whether or not your specific 2005 or older vehicle may be dinghy-towable.

Where can I locate my Vehicle Identification Number (VIN)?
Every automobile has a unique 17-character Vehicle Identification Number (VIN) that contains information about that vehicle. You can find your 17-character VIN:
  • At the base of your vehicle's windshield, on the driver's side
  • On your vehicle's registration
  • On your insurance statement or proof-of-insurance card
  • On your Acura Financial Services statement
  • On new user owner surveys or customer satisfaction surveys sent by American Honda Co.
What are the benefits of entering my VIN or HIN?
When you register for Acura Owners Site or add a new vehicle to an existing Acura Owners Site account, you have the option of entering your Vehicle Identification Number (VIN) or Hull Identification Number (HIN)

Benefits of entering your VIN include:

  • Quicker registration - our system "decodes" the VIN/HIN to determine your vehicle's year, make model, and color, so you don't have to enter it manually.
  • Current offers from your dealer, including sales and service specials
  • Up-to-date recall information for your specific vehicle.
  • Service reminders from your dealer
  • Entering your VIN or HIN will help you get the most out of Acura Owners Site. But don't worry if you don't have your VIN handy when you register. You can always enter it later by visiting your Acura Owners Account page.
How long do the batteries in the Tire Pressure Monitoring System (TPMS) sensors last?
The TPMS sensor batteries have an expected life of 7-10 years. When a battery in any of the sensors has died, the vehicle will illuminate the TPMS warning indicator on the gauge cluster. When the light is illuminated the system is no longer monitoring the vehicle’s tire pressure. Have your vehicle inspected by your local dealer if the indicator is illuminated.

For more information on this system and the sensor battery life, click here to watch this informational video.


Are some gasolines better than others? What is "Top Tier Detergent Gasoline"?
In general, Acura recommends that you buy gasoline from high-volume, major name-brand stations.

To prevent the build up of deposits inside your engine and fuel system, it is important to choose fuels that contain effective detergent additives. The detergency of some US gasoline is insufficient to provide protection from such deposits. Acura recommends the use of "Top Tier Detergent Gasoline," where available. Gasoline brands with this designation meet new, voluntary standards and have demonstrated their ability to keep engines clean through a series of demanding tests. Significantly, Top Tier Detergent Gasoline does not contain MMT, a metallic additive that creates deposits in your engine and exhaust system; (see the MMT explanation below). Fuel brands that have achieved the Top Tier Detergent Gasoline designation can be identified through their marketing campaigns, and/or by fueling station signage.

What's that sulfur smell coming from my vehicle?
All gasoline contains trace amounts of sulfur. The human sense of smell can detect sulfur odor in concentrations as low as 3 to 5 parts per million in air.

The exhaust on today's catalyst-equipped Acura vehicles will emit varying degrees of sulfur odor depending on operating temperatures and conditions. On normally operating vehicles, the odor is usually noticeable when the engine is cold, right after deceleration, or after wide-open throttle acceleration.

It may not be possible to eliminate sulfur odor completely due to the various operating conditions. If the sulfur odor is overly bothersome, please contact Acura Client Relations or your dealer for further guidance or assistance.

What is the difference between “Summer” and “Winter” Fuel?
All parts of the U.S. have winter/summer blended fuel, which is needed to prevent cold or hot start problems. Winter fuels have higher volatility to compensate for cold dense air. Conversely, summer fuels have lower volatility and are less prone to "percolate."

If winter blended fuel is used in warm or hot weather, the higher temperature may cause the fuel to "percolate" within the fuel system. Summer fuel may not vaporize adequately in cool weather.

These situations are normally localized and last only during a brief period of severe changes in climatic conditions. Normally, no vehicle repairs are needed for these situations.

To avoid a mismatch of summer and winter fuel, Acura recommends that you buy gasoline from high-volume, major name-brand stations.

Can I use E85 fuel in my Acura vehicle?
No. E85 is a fuel being promoted by some other vehicle manufacturers. No current Acura products are compatible with E85. Refer to the owner's manual for gasoline requirements. 
Can my Acura vehicle use fuel with 15% (E15) or 20% (E20) ethanol?
E15 fuel is approved for many 2014 and newer Acura vehicles. Please refer to the Owner's Manual for your vehicle for specific fuel recommendations. E20 is not approved for any Acura vehicles. 
Does it help to use a fuel with a higher octane rating than required in my Owner's Manual?
Refer to your Owner's Manual for the pump octane number recommended for your Acura. Use of a lower-octane gasoline than recommended can cause a persistent, heavy metallic rapping noise in the engine that can lead to mechanical damage.

There is no advantage in using a fuel with a pump octane greater than that recommended in your Owner's Manual.

Oils & Fluids

What type of oil should I use?
OIl Starburst Certification - For Gasoline Engines

It is very important to choose an oil displaying the "Starburst" certification symbol, shown at left. This symbol indicates that the oil meets the latest performance requirements set by the automotive and oil industries. Oil bearing the Starburst will provide superior performance in the areas of deposit and sludge protection, wear protection, and oil life. These oils will also protect the environment by extending the life of your emissions system and conserving energy through better fuel economy.

Acura recommends the use of Honda Genuine oil for your vehicle. This oil meets the Starburst performance requirements listed above, but is also subjected to a series of Acura-specific tests to guarantee optimum performance and compatibility with your Acura vehicle.

Lighter oils flow easier once the cold engine starts, bringing vital lubrication to moving parts. Refer to your Owner's Manual to determine the proper weight (viscosity) grade for your Acura. Your vehicle was designed to use this specific weight grade. Confirm that the weight listed on your oil's label matches this recommendation exactly before using it in your engine.

What about synthetic motor oils?
You may use a synthetic motor oil if it meets the same requirements listed above. That is, it must display the Starburst symbol, and match the weight grade recommended in your Owner's Manual.

When using synthetic oil, you must follow the oil and filter change intervals given in the maintenance schedule.

How often should I change my oil?
Refer to your Owner's Manual for the recommended service intervals. Separate maintenance schedules are listed for "normal service" and "severe service." Read the description of severe service carefully. Most vehicles will fall under the normal service category. Note that the service intervals are listed by time in addition to distance. Your oil should be changed at whichever interval, time or distance, occurs first.

There is absolutely no benefit in changing your oil more frequently than recommended in your Owner's Manual. This will only increase your cost of ownership, and create an unnecessary burden upon the environment by increasing the amount of disposed oil.

Do not exceed the recommended maintenance interval. Oil eventually deteriorates and loses its ability to protect your engine, due to heat, friction, and exposure to exhaust components. Engine oil contains special additives to enhance the oil's performance, and these additives are also broken down or consumed with distance and time. Engine damage can occur if the proper maintenance schedule is not followed.

What's a "crush washer" and why is it important to my Acura?
As an Acura owner, the crush washer you should be most concerned with is the one that must be replaced every time you change your motor oil. This crush washer fits between your oil pan and the drain plug. It is a one-time-use washer. Discard the old washer at each oil change and replace with a new one. If you have your oil changed at any service outlet other than an Acura dealer, remind them of the importance to use a new crush washer.

When a new washer is installed and the drain plug is tightened, this washer "crushes" to form a very tight seal, thereby preventing motor oil leaks without overstressing the oil pan threads.

Oil changers who are not aware of its importance may think it's OK to re-use this washer. Since it has already been crushed, it will not collapse further. As a result, the installer may over-tighten the drain plug to get a tight fit. This can eventually lead to stripped threads in the oil pan -- a very expensive repair.

This is another example of why your Acura dealer is the easy choice for your service needs. Acura dealers know your Acura best.

What about oil additives?
Acura recommends against the use of any oil additives other than those already blended in the stock oil. Such supplemental additives are unnecessary when using quality oils displaying the Starburst certification symbol. Additives cannot prolong the life of a used oil, because the oil molecules have been broken down. The use of oil additives will increase your cost of ownership, and can lead to engine damage.
Does my Acura need oil system flushing?
Acura strongly recommends against this process, which is sometimes called "engine flushing." Any engine damage resulting from this procedure will not be covered under warranty.
Are there special steps I should follow when changing my oil filter?
When installing a new Acura oil filter, make sure you torque the filter to the proper specification. This way, you fully compress the filter's O-ring so there are no leaks. Torque specifications are listed on the filter. Before you install a new oil filter, remember to inspect and clean the filter's threads and O-ring surfaces. And to keep the new O-ring from shearing when you torque the filter, smear a little engine oil on it. If the O-ring from the old filter is stuck to the engine block, scrape it off thoroughly and wipe the surface clean. Never install a new oil filter with the old O-ring stuck to the block. The filter could come loose over time.

Tires & Brakes

Does Acura recommend snow tires during the winter for better performance?
For most vehicles, Acura does recommend using snow tires or chains in snowy or icy conditions. Refer to your owner's manual for information and recommendations for your specific vehicle.
What are PAX Tires?
The PAX Tire System is the latest in "run-flat" tire technology that, in the event of a tire puncture, allows a driver to remain in control of the vehicle and continue driving for up to 125 miles at speeds up to 50 miles an hour on a deflated tire. For more information on PAX tires, go to
Can snow chains be used on PAX tires?
Yes, the recommendation for snow chains on vehicles with PAX tires is located in the owner's manual. It is recommended that customers contact their local auto parts store to obtain snow chains.
Can PAX tires be replaced with non-PAX tires?
No. PAX wheels will only accommodate PAX tires. Use of non-PAX tires will disable the Tire Pressure Monitoring System (TPMS) and is not recommended.
How far can a PAX-equipped vehicle be driven with a flat tire?
PAX-equipped vehicles may be driven up to 125 miles at up to 50 miles per hour.
How do PAX tires compare to regular tires for wear?
While tread life is determined by multiple variables that include speed, load, road surface abrasiveness and crown, driving habits and temperatures, PAX System tires should provide tread life comparable to a corresponding Michelin tire.
Can I change the size of the tires on my vehicle?
Acura does not recommend modifying the vehicle in any manner, including changing the original tire size or the suspension. Acura vehicles meet all applicable Federal Motor Vehicle Safety Standards when they are originally distributed, and modification could affect the safety and/or operation of the vehicle, as well as remove it from compliance with specifications and standards mandated by the Federal Government. As with any modification, if a failure occurs on the vehicle that can be attributed to the modification, the warranty on the affected components may be voided.
What do the sidewall markings on my tire mean?
The sidewall markings on a tire provide descriptive information about the tire's design. The following refers to the tire illustration below with the sidewall marking of 225/50R16:
  • 225 - This number specifies the width in millimeters (i.e. 225 mm).
  • 50 - This number is the Aspect Ratio, the ratio of sidewall height to width.
  • R - Radial
  • 16 - This number designates the tire's diameter in inches (i.e. 16").
  • 92 - This number indicates the tire's load-carrying capacity, known as the Load Index; as the number for the load index increases so does the load-carrying capacity. (All passenger car tires in the U.S. are also marked with their actual load limit in pounds.)
  • V - This letter denotes the Speed Rating, the maximum tire speed under controlled test conditions. (“V” in this example is one of several types of speed ratings.)
  • psi (pounds per square inch) - The maximum cold inflation rating for the tire.
  • DOT (Department of Transportation) - This symbol indicates the tire meets or exceeds U.S. DOT safety standards; the letters and numbers following the DOT symbol provide information about the tire manufacturer, tire size, and the date it was manufactured.

Tire Sidewall Markings Chart

Why do my brakes make a squealing noise sometimes when I apply them lightly at low speeds?
As described in some Owner’s Manuals, the squealing noise is caused by high-frequency vibration of the brake pads against the rotating brake disc. Vibration is the unavoidable result of friction generated by the pads as the caliper clamps them against the rotating disc. Under average braking conditions, some brake noise is normal and cannot be eliminated.

Normally, the shims and the high-temperature grease between the pads and the brake caliper dampen and isolate most of the vibration. The level of vibration, however, is affected by outside temperature and humidity, by road conditions (mud, dust and road salt), and by the condition or thickness of the brake pad material. If the squealing noise is abnormally loud, have the brakes inspected and checked for pad wear.

Why do my brakes make a single “click” noise when I back out of a parking place and once again when I drive forward?
A clearance between the brake caliper brackets and the ends of the brake pads allows for heat expansion and avoids corrosion between the caliper bracket and the brake pads. That clearance can cause the pads to hit the caliper brackets when you first apply the brakes in a new direction of travel. When you back up and apply the brakes and then drive forward and apply the brakes, the single “click” noise you hear is a normal characteristic of the brake system.
Why does my brake pedal sometimes feel like it sinks when I’m holding my car stopped at a light?
This change in brake pedal height is caused by an increase in engine vacuum. The “power brakes” system in most modern vehicles uses engine vacuum to boost the amount of force applied to the brake pedal by the driver of the car. The device that does this, called the brake “booster,” makes it easier for the driver to stop the vehicle.

Engine vacuum is affected by many different conditions. Engine vacuum is highest when all accessories are off and the accelerator pedal is released (low load), and lowest when all accessories are turned on and the accelerator pedal is held to the floor (high load). Any change in engine vacuum (load) can affect the amount of “assist,” or boost, provided by the brake booster.

One system that applies a noticeable load to the engine is the air conditioning. During normal operation, the air conditioning system constantly cycles on and off, changing the amount of load on the engine. When the air conditioning cycles off, the load on the engine is decreased and the amount of engine vacuum is increased. If the driver is applying the brake pedal when the air conditioning cycles off, the increase in engine vacuum increases the amount of boost applied to the brake pedal. That increase is felt as a slight drop in brake pedal height and is a normal characteristic.

Why do I hear a groaning noise when I start my car and then leave for work in the morning?
On models with a compact Anti-lock Brake System (ABS) unit, the vehicle’s ABS emits a brief grunt or groan when it does a self-check. The self-check occurs when a vehicle is backed up or driven forward after being started. The groaning noise associated with the ABS self-check is a normal characteristic; it doesn’t mean there is a problem with the ABS.

Parts & Accessories

Does Acura offer seat belt extenders to increase the length of the seat belt?
No, Acura does not offer seat belt extenders for any of our vehicles. Although some auto manufacturers do offer extenders, Acura believes they are not the best or the safest solution for our customers. As required by Federal Standards, Acura's seat belts are designed to fit 95% of all U.S. adults in any seating position.

Before buying a car, you should first sit in the intended seating position and adjust the seat to the most comfortable position. If you don't feel comfortable (your legs or stomach are touching the steering wheel, or you cannot reach and operate the controls), then you cannot safely operate the vehicle and should look for a larger car.

How can I get a replacement key for my Acura vehicle?
Any Acura dealer can provide you with a replacement key.
My USB Audio Interface doesn’t play music after upgrading to OS 4.0 on my iPhone/iPod touch.
A hard reset (complete power off) to the device should resolve this problem. To perform a hard reset, hold the home button (below the screen) and the stand-by button (on the top) until the device reboots (ignore the “slide to power off” and wait until the Apple logo appears).

Note: if a non-reset OS 4.0 iPhone/iPod touch is connected to the vehicle and disconnected, other OS 3.x iPods/iPhones may not work until the vehicle has been restarted.

Where can I find out more about Bluetooth HandsFreeLink (phone compatibility, pairing a phone, etc)?
For information about Bluetooth HandsFreeLink (HFL), such as checking phone compatibility, how to pair a phone, or importing an address book, please visit or call (888) 528-7876.

Radio & Navigation

What is a Navigation Code and where can I find it?
The Anti-theft Navigation Code is an access code that allows the Navigation System to operate. If your battery is ever disconnected, the navigation system will be automatically deactivated. It can only be reactivated by entering the Navigation Code. If your Acura came equipped with a Navigation System, you should have a Navigation Code access card in your glove compartment. This card contains the access code and the serial number of the navigation unit. If you do not have a card, click on link to Retrieve your Acura Radio code online.

Warranty transferability
Acura warrantees the vehicle regardless of the number of ownership changes it incurs. In fact, the back cover of your Acura Warranty Information booklet contains a "Change of Address or Ownership Notification" form for that purpose. In case of safety recalls, product updates, etc., we need to know who to notify. Whenever you move or sell the car, please complete the form and send it to us promptly.
Non-Dealer service
Your warranty will not be voided by service done by someone other than an Acura dealer provided the maintenance is performed properly. The only way your warranty may be affected by an outside service is if it can be shown that misuse or improper (or lack of) maintenance caused or contributed to the malfunction.
Are Acura replacement parts covered under warranty?
Acura Genuine Parts are covered by a 1 year Replacement Parts Limited Warranty. The warranty coverage for parts purchased from and installed by an Acura dealer includes parts replacement and labor. Every Acura Genuine Remanufactured Part is backed with our 3 year / 36,000 mile nationwide Remanufactured Parts Limited Warranty.
If my vehicle has a branded or “Salvage” title, is the warranty still valid?
Vehicles with titles that have been branded as salvaged, scrapped, or dismantled are no longer covered by the new car warranty, with the exception of some emissions warranties and safety recalls. For further information regarding the branding of vehicle titles, please contact your state’s department of motor vehicles.
Who should I contact regarding the tire warranty on my Acura vehicle?
The tires that come as original equipment on your vehicle are warranted by their manufacturer and not Acura. The tire warranty information is located in the glove compartment of the vehicle.

For additional warranty information or service assistance, contact the tire manufacturer directly.

My new car is under factory warranty. Why should I buy a service contract?
Service contracts go above and beyond your car's standard factory warranty. The comprehensive exclusionary coverage of Acura Care cover virtually every component of your vehicle, including drive train, electronics, chassis, cooling/heating and genuine factory accessories.
When does coverage for a service contract begin?
Coverage for a new-vehicle plan begins when the auto is originally put into service and at zero miles. Coverage for a used-vehicle plan begins on the purchase date and at the mileage on the odometer on that date.
Can I finance the cost of an Acura Care contract?
Yes. With our special interest-free payment plan, a monthly payment can be automatically debited from your checking account, MasterCard or Discover Card.
Can I include the cost of an Acura Care service contract in my traditional financing or lease payment?
Yes. You may finance the cost of a service contract if you purchase it at the same time as a new or used automobile.
Is an Acura Care contract transferable if I sell my vehicle?
Yes. Coverage is transferable from private party to private party through the life of the vehicle service contract.

When cruising on the highway I sometimes feel a light vibration. Is this normal?
Acura vehicles with V6 engines equipped with Variable Cylinder Management (VCM) are able to deactivate engine cylinders to improve fuel economy. These engines are equipped with technology to dampen and decrease the vibration of the engine when cylinders are deactivated. While these systems effectively decrease the amount of vibration transmitted to the passenger cabin, you may still notice a light vibration when the engine is running on 3 or 4 cylinders during light cruising.
