You can activate this feature by sliding the lever located on the right side of the instrument panel toward warm or cool. If the passenger climate control has been turned on, it can be turned off by pressing the OFF button once. Pressing the OFF button a second time will turn off the main system. NOTICE: Don't use a razor blade or something else sharp on the inside of the rear window. If you do, you could cut or damage the warming grid or the integrated rear window antenna, and the repairs wouldn't be covered by your warranty. Passenger Climate Control Ventilation System For mild outside temperatures when little heating or cooling is needed, use VENT to direct outside air through your vehicle. Air will flow through any of the outlets depending on outside temperatures and comfort level settings. Your vehicle's flow-through ventilation system supplies outside air into the vehicle when it's moving. When the vehicle is not moving, you can get outside air to flow through by selecting any air choice (except the rear window defogger) and any fan speed. 3-7
