Climate Control

Climate Control

Your Acura is equipped with a state-of-the-art climate control system that makes traveling comfortable year-round, regardless of the weather. The system is enhanced with permanent controls on the On Demand Multi-Use Display™ (ODMD™), which offers many large and instantly readable controls to use to customize your environment. Here are some of the subjects of inquiry many drivers have regarding their climate control systems:

Controlling the source of air

The Recirculation control determines the source of the air going through your climate control system. When in Recirculation Mode, air from the vehicle's interior 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 this mode, however, can cause the windows to fog, especially with the A/C off.

Source of outside air coming into the vehicle

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

Air exit locations

After circulating the air through the interior, the flow-through ventilation system exhausts it through vents near the rear window.

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

To manually turn on the A/C, start the engine, press the A/C status button on the ODMD™, and on the display, set the AC to On. A green light will appear next to A/C on the status button. You can set your desired temperature with either the ODMD or hard button, or simply set the control for maximum cooling. Open the windows partially and select recirculate with the ODMD status button. Once the cool air has replaced the warm air, close the windows, switch to Fresh Air Mode, set the desired temperature, and press the AUTO button to maintain the setting.

Air conditioning noise in engine

Air conditioning places an extra load on the engine, especially when driving in stop-and-go traffic or climbing 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 at the same time. As the 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

Switch 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 select defrost. Switch 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 away.

Caring for the A/C system

Run the air conditioning at least once a week during the cold weather months. Run it 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.
