Climate Control

GPS Climate Control

The GPS-linked automatic climate control system further enhances occupants' comfort level by tracking the sun's position and intensity. The GPS* positioning technology monitors the sun's location relative to the car's position while a sensor on the dash measures the sun's intensity. By knowing which part of the cabin is receiving the sun's rays, the system compensates to keep each side of the cabin at its designated temperature. The system is completely automatic and requires no manual adjustments, regardless of outside conditions.

Climate Control Manual Use

The TL is equipped with a state-of-the-art climate control system that makes traveling comfortable year-round, regardless of the weather. Here are some subjects of inquiry many drivers have regarding their climate control systems:

Controlling the source of air

The Recirculation Button controls the source of the air going through your climate control system. When in Recirculation Mode, air from the vehicle's interior (as opposed to incoming air from the exterior with Fresh Air mode) is recirculated through the system. Use this mode when driving through smoky or dusty conditions, or when you need maximum A/C cooling. Keeping the system in Recirculation Mode, however, especially with the A/C off, can cause the windows to fog.

Source of outside air coming into the vehicle

Air intakes for both heating and cooling are at the base of the windshield. Keep these areas clear of leaves and other debris for optimal operation.

Air exit locations

After circulating the air through the interior, the flow-through ventilation system exhausts it through vents near the rear window. Keep these areas clear of objects and other debris for optimal operation.

Cooling down the vehicle after it's been sitting in the sun

Start the engine and press the A/C Button to turn on the A/C. Make sure the temperature is set at the lowest. Set the fan to maximum speed. Open the windows partially and select Recirculation Mode. Once the cool air has replaced the warm air, close the windows, switch to Fresh Air Mode and turn the fan to the desired setting.

Air conditioning noise in the engine compartment

Air conditioning places an extra load on the engine, especially when driving in stop-and-go traffic or driving up a long, steep hill. You may hear a noise when your compressor engages, but there is nothing wrong with the engine. If any noise does concern you, contact your Acura dealer.

Making the interior drier and warmer

Use the air-conditioning and heating systems at the same time. As the cabin interior cools, the A/C draws moisture out of the air. When used with the heater, it makes the interior drier and warmer. This procedure works whenever the outside temperature is above 32 degrees Fahrenheit.

Removing fog from windows

Turn on the fan, the defroster, and the A/C. Adjust the temperature control so the air flow from the defroster feels warm. Turn on the rear window defogger.

Removing frost and ice from the windshield exterior

Start the engine and turn on the windshield defroster. Turn the fan and temperature controls to maximum. To rapidly remove exterior frost or ice from the windshield, first select Recirculation Mode. Once the windshield is clear, select Fresh Air Mode to avoid fogging the windows. The air will get warmer and clear the windows faster as the engine warms up. Once the windows clear, close the side vents with the dial beside each vent. This will send more air to the windshield defroster vents. For safety, make sure you have a clear view through all the windows before driving.

Caring for the A/C system

Run the air conditioning at least once a week during the cold weather months. Do this for at least 10 minutes while driving at a steady speed with the engine at normal operating temperature. This circulates the lubricating oil contained in the refrigerant. In cold weather, never turn the fan off except during the first few minutes of operation. Your climate control system will work best if you keep air circulating.
