Comfort Controls This section tells you how to use the comfort controls. With these systems, you can control the heating, cooling and ventilation in your vehicle. Your vehicle also has a flow-through ventilation system described later in this section. Manual Dual Zone Comfort Controls Comfort Controls Personalization (If Equipped) If your vehicle is equipped with the automatic comfort control system and memory seats and mirrors, you can store and recall the climate control settings for temperature, air delivery mode and fan speed for two different drivers. The personal choice settings recalled are determined by the transmitter used to enter the vehicle. After the button with the unlock symbol on a remote keyless entry transmitter is pressed, the climate control will adjust to the last settings of the identified driver. The settings can also be changed by pressing one of the memory buttons (1 or 2) located on the driver's door. When adjustments are made, the new settings are automatically saved for that driver. With this system, you can select different comfort control settings for the driver and passengers. Fan Knob The knob on the left side of the climate control panel regulates the fan speed. You can choose from five different fan speeds or turn the fan off. Driver's Side Temperature Lever The lever on the left side of the climate control panel is used to adjust the air temperature on the driver's side, independent of the temperature set by the passenger. Slide the lever upward to raise the temperature. Slide the lever downward to lower the temperature. 3-2
