Activating/deactivating
WARNING
Any accumulation of snow and ice should be
removed from the rear window before driving.

► Turn the SmartKey to position 2 in the
ignition lock.
► Press the
button.
The indicator lamp in the button
lights
up or goes out.
Problems with the rear window defroster

defroster button flashes, the on-board
voltage is too low or the roof is open. The rear
window defroster has deactivated itself
prematurely or cannot be activated.
► Switch off any consumers that are not required, e.g. reading lamps or interior lighting.
When the battery is sufficiently charged, the rear window defroster is activated again automatically.
