Passenger Temperature Control
If your vehicle has this feature, then the driver and the
front-seat passenger can select separate temperature

the driver's selected temperature. The control is
located on the passenger's door armrest.
Press the red button for a warmer temperature or the
blue button for a cooler temperature. Press the
OFF button on the main system once to turn off the
passenger's temperature control. Press the OFF button
twice to turn off the entire climate control system.
