Problems with the rear window heating
Problem
The rear window heat-
ing has switched off

culation mode briefly to prevent the windows

You can deactivate the flow of fresh air if
unpleasant odours are entering the vehicle

cle will then be recirculated.
The operation of air-recirculation mode is the
