Driver and Passenger Side Temperature Controls

The driver and passenger side temperature buttons are used to adjust the temperature of the air coming through the system on the driver or passenger side of the vehicle. The temperature can be adjusted even if the system is turned off. This is possible since outside air always flows through the system as the vehicle is moving forward unless it is set to recirculation mode. See “Recirculation” later in this section.

Press the + or − buttons to increase or decrease the cabin temperature.

The driver side or passenger side temperature display shows the temperature setting increasing or decreasing.

The passenger temperature setting can be set to match the driver temperature setting by pressing the PASS button and turning off the PASS indicator. When the passenger temperature setting is set different than the driver setting, the indicator on the PASS button illuminates and both the driver side and passenger side temperature displays are shown.

When in defrost mode the passenger temperature setting cannot be changed.
