Climate Controls Operation in the recirculation mode while the air conditioner is off increases humidity and may cause the windows to fog. Recirculation is not available in the defrost or defog modes. Do not drive the vehicle until all windows are clear. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. Press to turn on or off. See Heated Front Seats on page 3‑7. 8-3 Passenger Compartment Air Filter The passenger compartment air filter removes most of the pollen and dust from the air that enters the vehicle. The filter will need to be replaced periodically. See Scheduled Maintenance on page 11‑2. Using the climate control system without an air filter installed is not recommended. Water or other debris could enter the system and result in leaks or noises. Always install a new filter when removing the old filter. Rear Window Defogger < (Rear Defogger): Press to turn the rear window defogger on or off. The rear window defogger turns off automatically after about 12 minutes. It can also be turned off by turning the ignition to ACC/ACCESSORY or LOCK/OFF. If turned on again it runs for about six minutes before turning off. At higher vehicle speeds, the rear defogger can stay on continuously. L / M (Heated Seats):
