Temperature The knob on the right of the climate control panel is the temperature adjustment that can be used with any of the climate control modes. Turn the knob clockwise for warmer settings and counterclockwise for colder settings. For quicker cool down on hot days, do the following: 1. Select the vent/outside air mode. 2. Select the recirculation mode. 3. Select the air conditioner. 4. Select the coolest temperature. 5. Select the highest fan speed. 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, select the vent mode once the interior of the vehicle is cooled. 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. Air Conditioning #(Air Conditioner): Press this button on the climate control panel to turn the air-conditioning system on or off. When A/C is pressed, an indicator light to the right of the button will come on to let you know that A/C is active. The instrument brightness control may have to be adjusted to the highest setting during the daytime in order to see the indicator lamp. On hot days during initial start-up, 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. 3-27
