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
wiping to fast wiping .
® -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. ..,_

-Do not use the wipers to clear a window
that is covered with frost. Using the wip­
ers as a convenient ice scraper will
destroy the wiper blades.
@ Tips
- The windshield wipers switch off when
the ignit ion is turned off. You can acti­
vate the windshield wipers after the igni­
tion is switched back on by moving the
windshield wiper lever to any pos ition.
- Worn or dirty windshield wiper blades
result in streaking. This can affect the
rain sensor funct ion. Check your wind­
sh ield wiper blades regularly.
- The washer fluid nozzles in the w ind­
sh ield washer system are heated" at low
temperatures when the ignit ion is on.
- When stopping temporarily, such as at a
traff ic light, the speed of the windsh ield
wipers automatically reduces by one lev­
el.

Driving 71
- Never remove the ignition key from the
ignit ion lock while the vehicle is mov ing.
Otherwise the steering lock will engage
and you will not be able to steer the vehi­
cle.
- The brake booster and power steering
only work when the eng ine is running. If
the engine is off, you have to use more
force when stee ring or braking. Because
you cannot steer and bra ke as you usual­
ly would, this could lead to crashes and
serious inju ries .
- Always take the vehicle key with you
when leaving the vehicle, even for a
short period of time . This applies partic­
ular ly when c hildren remain in the vehi­
cle. Otherwise the children could start
the engine or operate electrical equip­
ment such as power windows.
(D Note
- Avoid high engine speed, full th rottle,
and heavy engine load as long as the en­
gine has not reached operating tempera­
ture yet. You could damage the engine.
- The engine cannot be started by pushing or towing the vehicle.
@ For the sake of the environment
Do not let the engine run while parked to

The locked steering helps prevent vehicle
theft.
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
brake as you usually would, this could
lead to accidents and serious injuries.
- Never remove the ignition key from the
ignition lock while the vehicle is moving.
Otherwise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- 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 engine 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 Note
-If the engine has been under heavy load
for an extended period of time, heat builds up in the engine compartment af­
ter the engine is switched off -there is a
risk of damaging the @ngin@ . For this
reason, let the engine run for at idle for
approximately two minutes before shut ­
ting it off.
(D Tips
-After the engine has been switched off,
the radiator fan can continue to run for
up to 10 minutes -even with the ignition
