Problem
The rear window heating has switched it-
self off prematurely or cannot be switched
on.
The cooling system cannot be switched on
using COMAND.
The 9 warning lamp to the right
of the instrument cluster is lit.
Possible cause
There is insufficient voltage because too
many consumers are switched on, e.g.
reading lamps, interior lighting.
The cooling system is losing refrigerant.
A child seat is fitted to the front-passen-
ger seat. The front-passenger airbag has
therefore been deactivated.
G
Risk of injury
There is no child seat fitted to the front-
passenger seat. The child seat recognition
is faulty.
Practical advice
Troubleshooting
Suggested solutions
Switch off consumers that are not re-
quired, e.g. reading lamps, interior light-
ing.
The rear window heating will automati-
cally switch back on as soon as there is
sufficient voltage again.
Have the automatic air conditioning
checked at a qualified specialist work-
shop.
Remove transponder cards, e.g. ski
passes, from the vicinity of the seat
cushion.
Have the child seat recognition checked
at a qualified specialist workshop.
