Temperature Control
The driver and passenger side temperature buttons are used to adjust the temperature of the air coming through the system. The temperature can be adjusted even if the system is turned off since outside air still enters the vehicle, unless the recirculation mode is selected. See “Recirculation” later in this section.
Driver Side Temperature Control: Press the + or − buttons to increase or decrease the driver side temperature. The driver side temperature display will show the temperature setting.
Passenger Side Temperature Control: Press the + or − buttons to increase or decrease the passenger side temperature.
The passenger side display will show the temperature setting.
PASS (Passenger): Press to set the passenger temperature to match the driver temperature setting.
The PASS indicator will turn off.
When the passenger temperature setting is different than the driver setting, the PASS indicator comes on.
