Windshield wipers without rain sensor*
At speeds of approximately 105 mph
(170 km / h) the wiper switches automati-
cally to continuous wiping. Always obey lo-
cal speed limits.Windshield wipers with rain sensor*
A rain sensor automatically controls the
windshield wipers depending on how wet
the windshield is.

Switch on ignition.

Set the wiper switch to position1
(page 49).
After the initial wipe, pauses between
wipes are automatically controlled by the
rain sensor which monitors the wetness of
windshield.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
iWhen intermittent wiping is on and the
key is turned from position1 to
position2 in the steering lock
(page 33), and kept in that position
for longer than two seconds, the wipe
interval will be set to approximately
five seconds.
!Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.

Rear window defroster
The rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, switch off the defrost-

off too soon and the indicator lamp
starts flashing, this means that too
many electrical consumers are operat-
ing simultaneously and there is insuffi-
cient voltage in the battery. The system
responds automatically by deactivating
the rear window defroster.
As soon as the battery has sufficient
voltage, the rear window defroster au-

136 Controls in detailAutomatic climate controlThe automatic climate control is operatio-
nal whenever the engine is running. You
can operate the climate control system in
either the automatic or manual mode. The
system cools or heats the interior depend-
ing on the selected interior temperature
and the current outside temperature.
Nearly all dust particles, pollutants and
odors are filtered out before outside air en-
ters the passenger compartment through
the air distribution system.Warning!
G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents in the
footwell can be very hot or very cold (de-
pending on the set temperature). This may
cause burns or frostbite on unprotected skin
in the immediate area of the air vents.
Always keep sufficient distance between un-
protected parts of the body and the footwell
air vents. If necessary, change the air flow
using the air distribution controls to direct
the air away from the footwell air vents
(page 138).
Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
iSevere conditions (e.g. strong air pollu-
tion) may require replacement of the fil-
ter before its scheduled interval. A
clogged filter will reduce the air volume
to the interior.
If the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not touch the interior temperature
sensor to maintain a precise tempera-
ture.
The set value is indicated by a lighted
segment on the control wheels.
