Problems with the seat heating
ProblemPossible causes/consequences andMSolutions
The seat heating has
switched off prema-
turely or cannot be
switched on.The on-board voltage is too low because too many electrical con-
sumers are switched on.

the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating will
switch back on automatically.

ing wheel and mirror and fasten your seat belt before starting the vehicle's drive system.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.

exterior mirror to the correct position. You
should have a good overview of traffic con-
ditions.
The convex exterior mirrors provide a larger
field of vision.
After the engine has been started, the exte-
rior mirrors are automatically heated at low
outside temperatures. Heating takes a maxi-
mum of ten minutes.
iYou can also heat up the exterior mirrors
manually by switching on the rear window
defroster.

Switching cooling with air dehumidi-
fication on/off
General notes
If you deactivate the "Cooling with air-dehu-
midification" function, the air inside the vehi- cle will not be cooled. The air inside the vehi-
cle will also not be dehumidified. The win-
dows can fog up more quickly. Therefore, only
deactivate the "Cooling with air-dehumidifi-
cation" function briefly.
The "Cooling with air-dehumidification" func-
tion is operational when the vehicle is ready
to drive. The air inside the vehicle is cooled
and dehumidified according to the tempera-
ture selected.
Condensation may drip from the underside of
the vehicle when it is in cooling mode. This is
normal and not a sign that there is a malfunc- tion.
