yPASS TEMP z (Passenger's Temperature): Press this switch to turn the passengers' climate control systems on. Press this switch to manually increase or decrease the temperature for the front passenger. PASS OFF (Passenger's Climate Control): Press this button to turn all passenger climate control systems off. If the passenger's temperature switch is turned off, the driver's temperature knob will control the temperature for the entire vehicle. A/C (Air Conditioning): Press this button to override the automatic system and turn the air-conditioning system on or off. When in AUTO the air-conditioning compressor will come on automatically, as necessary. On hot days, open the windows to let hot inside air escape; then close them. This helps to reduce the time it takes for your vehicle to cool down. It also helps the system to operate more efficiently. For quick cool down on hot days: 1. Select the vent mode. 2. Select the recirculation mode. 3. Select A/C. 4. Select the coolest temperature. 5. Select the highest fan speed. 6. Open all outlets. Using these settings together for long periods of time may cause the air inside your vehicle to become too dry. To prevent this from happening, after the air in your vehicle has cooled, turn the recirculation mode off. The air-conditioning system removes moisture from the air, so you may sometimes notice a small amount of water dripping underneath your vehicle while idling or after turning off the engine. This is normal. If your vehicle has the memory option, it can be used to recall your climate control settings. For more information, see Climate Controls Personalization on page 3-40. 3-33
