Problems with the windshield wipers
ProblemPossible causes/consequences andMSolutions
The windshield wiper
jams.Leaves or snow, for example, may be obstructing the windshield wiper
movement. The wiper motor has switched off.
XStop the vehicle as soon as possible, paying attention to road and
traffic conditions.
XFor safety reasons, you should remove the key from the ignition
lock.
XRemove the cause of the obstruction.
XSwitch on the windshield wipers again.

does not move at all.There is a malfunction in the windshield wiper drive.
XSelect another wiper speed on the combination switch.
XHave the windshield wipers checked at a qualified specialist work-
shop.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 26).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could fog
up.
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
iVentilate the vehicle for a brief period during
warm weather. In order to cool the vehicle
more rapidly, switch climate control to air-
recirculation mode briefly. This will speed up
the cooling process and the desired interior
temperature will be reached more quickly.
iThe integrated filter can filter out most par-
ticles of dust and completely filters out pollen.
A clogged filter reduces the airflow into the
vehicle interior. For this reason, you should
always observe the interval for replacing the
filter, which is specified in the Maintenance
Booklet. As it depends on environmental con-
ditions, e.g. heavy air pollution, the interval
may be shorter than that stated in the Main-
tenance Booklet.

mally.
RSet the temperature control to the middle
level. Only change the temperature in small
increments.
If you wish to heat up the vehicle interior as
quickly as possible, set the temperature con-
trol to thezmaximum setting. When the
desired interior temperature has been
reached, turn the temperature control back
down in small steps.
ROnly use the settings for defrosting the wind-
shield briefly, until the windshield is clear
again.
ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the
h button comes on when the function is
switched on.

intake and air circulation also stop. Only use this
setting for a brief period. Otherwise, the win-
dows could fog up.

Switching the cooling with air dehu-
midification function on/off
Important information
If you switch off the "Cooling with air dehumid-
ification" function, the air inside the vehicle will
not be cooled (in warm weather) or dehumidi-
fied. The windows could fog up more quickly.
The cooling with air dehumidification function is
only available when the engine is running. The
air inside the vehicle is cooled and dehumidified
according to the temperature selected.
Condensation may appear on the underside of
the vehicle when in cooling mode. This is normal
and not a sign that there is a malfunction.
Switching on and off
