Problems with the rear window defroster

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.
