Requirement : The ignition must be turned on.
Move the windshield wiper lever to the corre­
spond ing position:
@ -Front wipers off
(D -Interval mode. To increase/decrease the
wiper intervals , move the switch @ to the
left/right. In vehicles with a light/rain sen­
sor*, the wipers turn on when it is raining,
when the vehicle is stationary and the lever is
tapped in the ® position, or once the vehicle
speed exceeds approximate ly 2 mph (4 km/h) .
The higher the sensitivity of the rain sensor is
set (sw itch @ to the right), the earlier the windshield wipers react to moisture on the
windshield.
@ -Slow w iping
@ -Fast wip ing
@ -Single wipe . If you ho ld the lever in this
position longer, the wipers switch from slow

® -Clean the windshield. To elim inate water
droplets, the windshield wiper performs one
afterwipe after several seconds in tempera­
tures above 39 °F (4 °() . You can switch th is
function off by moving the lever to pos it ion ®
within 10 seconds after the afterwipe . The af­
terwipe function is reactivated the next time
you sw itch the ignition on.
_& WARNING
- The rain sensor is only intended to assist
the driver. The driver is still responsib le
for manually switching the wipers on ac­
cording to the visibility conditions .
- The windshield may not be treated with
water-repelling windshield coating
agents. Unfavorable conditions, such as
wetness, darkness or low sun, can result in increased glare. Wiper blade chatter is
also possible .
- Properly functioning windshield wiper
blades are requ ired for a clear view and
safe driving

front windshield wiper blades .
(D Note
-In case of frost, make sure the w ind­
shield wiper blades are not frozen to the
w indshield . Switching on the windshield
w ipers when the blades are frozen to the
windshield can damage the wiper blades.
- Pr ior to using a car wash, the w indshield
w iper system must be sw itched off ( lever
in posit ion 0). This prevents unintention­
al swi tchi ng on and damage to the wind-
shield wiper system. ..,_

CD Note
-For vehicles with power folding exterior
mirrors *:
If the m irror housing was
moved by outside forces (such as an im­
pact w hen maneuvering), you must use
the power folding function to fold the mirro r all the way out. You will hear a
l oud noise when the mirrors are latched
back in place . T he mirror housing must
no t be moved back into place by hand
because th is would affe ct the mirror
mechanism.
- Applies to vehicles witho ut powe r fold­
ing exterior mirro rs :
If the mirror hous­
i ng was moved by o utside forces (s uch as
i n impact d uring maneuvering), you
must move the mirror housing back into
place by hand.
- If you wash the ve hicle in an automatic
car wash, you must fold the exterior m ir­
ro rs in to reduce the r isk of damage to
the mirrors . Never fold power foldi ng ex ­
te rior mirrors by hand . Only fold them in
and out using the power cont ro ls.
(D Tips
If the power adjustment fails, both mir­
rors can be adjusted by hand by pressing
on the edge of the mi rror surface.

(D Tips
-After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first build up in the hydraulic valve adjusters. This is
normal and not a cause for concern.
- If the . indicator light blinks in the in­
strument cluster before switching the ig­
nition off, the ignition will not switch on
again
Qpage 189.
-If you leave your vehicle with the ignition
switched on, the ignition will switch off
after a certain amount of time. Make
sure that electrical equipment such as
the exterior lights are switched off.
Turning th n ine off using the

the
I START ENGINE STOP !* button twice in a
row briefly or press and hold for longer than
two seconds.
A WARNING
- Never turn off the engine before the ve­
hicle has come to a complete stop . The
full function of the brake booster and the
power steering is not guaranteed . You
must use more force to turn or brake, if
necessary. Because you cannot steer and
b rake as you usually would, this could
lead to accidents and serious injuries.
- The brake booster and power steering
only work when the engine is running . If
the engine is off, you have to use more
force when steering or braking. Because
you cannot steer and brake as you usual­
ly would, this could lead to crashes and
serious injuries .
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time . This applies partic­
ularly when children remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
- For safety reasons, you should always
park your vehicle with the selector lever
in P. Otherwise, the vehicle could inad­
vertently roll away.
-After the eng ine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
switched off. It can also switch on again
after some time if the coolant tempera­
ture rises as the result of a heat buildup or if the engine is hot and the engine
compartment is additionally heated by
the sun's rays.

(D Tips
-You can set the parking brake at any time
-even with the ignition turned
off. To re-
lease the parking brake, the ignition
must be turned on and the brake pedal
must be pressed.
- If driver 's door is opened while the igni­
tion is switched on, the parking brake
sets automatically. This prevents unin­
tended rolling of the vehicle .
- Occasional noises when the parking
brake is set and released are normal and
are not a cause for concern.
- When the vehicle is parked, the parking
brake goes through a self -test cycle at
regular intervals. Any noises associated
with this are normal.
- If there is a power failure, the parking
brake will not set if it is released, and it
will not release if it is set ¢,&. . See your

What can ad apti ve crui se contr ol do ?
The adaptive cruise contro l system uses radar
and a video camera. The radar is subject to
designated system limits¢

On open roads with no traffic, it functions like
a cruise contro l system. The stored speed is
maintained. When approaching an object
ahead and the system detects it, the adapt ive
cru ise control system automatically brakes to
match that object's speed and then maintains
the stored d istance. As soon as the system
does not detect an object ahead, adaptive
cr uise contro l accelerates up to the stored
speed.
Applies to vehicles w ith an automatic trans­
