Your Honda is equipped with a state-of-the-art climate control system that makes traveling comfortable year round, regardless of the weather. Here are some of the subjects that many drivers have questions about 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 the Recirculation Mode, air from the vehicle's interior is re-circulated through the system. Use this Recirculation Mode when driving through smoky or dusty conditions, or when you need maximum A/C cooling. Keeping the system in the 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 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 vehicle after it's been sitting in the sun
Start the engine and push the A/C Button to turn on the A/C. Make sure the temperature control lever is all the way to the left. 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 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 Honda dealer.
Making the interior dryer and warmer
Use the air-conditioning and heating at the same time. As it cools, the A/C draws moisture out of the air. When used with the heater, it makes the interior dryer 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 the maximum. To rapidly remove exterior frost or ice from the windshield, first select the Recirculation Mode. Once the windshield is clear, select the 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 ten 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.
