Press to defrost the rear window and door mirrors.
The rear window and door mirrors are defrosted simultaneously if the switch is pressed once.
The defrost function is active if the LED in the switch is illuminated.
The function can be switched off manually by pressing the button.
The defrost function switches off automatically after 12-20 minutes, depending on the outside temperature.
NOTE
On certain markets, the defrost function may remain on longer than 20 minutes in cold weather to help keep the rear
window free from ice or condensation.
10. Temperature selector
The temperatures on the driver's and passenger's sides can be set separately using the knob (with the thermometer in
it). The temperature can be set for both sides of the vehicle when the ignition is switched on (both LEDs will be on),
which means that a temperature setting will apply to both sides of the car.
To set the temperature on one side of the car:
Press the knob once. The LED for one side of the vehicle will light up. Turn the knob to adjust the temperature.
Press the knob a second time to set the temperature on the opposite side of the car.
Press the knob a third time to set the temperature on both sides of the vehicle at the same time.
NOTE
Selecting a temperature that is higher or lower than necessary will not heat or cool the passenger compartment faster.
