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
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
c::> page 47, Replacing
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. ..,_

loading the roof rack
Always distribute loads evenly . Make sure
anything on the roof rack is securely tied
down.
,. Always distribute the loads on the roof rack
evenly .
,. Always attach items to the roof rack securely
before you d rive off.
The maximum perm iss ible roof we ight is
165 lb (75 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You m ust also
not exceed the maximum load weight for the
roof rack you are using.
When us ing a roof rack system which has a
l owe r load carry ing capac ity, you must not use
up the total max imum pe rm issib le load carry ­
i ng capac ity specified above. Instead, you
should load the roof rack system only to the
maximum capacity specified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause se rious personal injury .
- Make sure the roof rack is insta lled exact­
ly as specified above¢
page 59.
-Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shift ing o r fly ing for­
ward.
- Items on the roof rack must always be sec urely mounted.
- The use of a roof rack can negative ly af­
fect the way a vehicle handles . Ca rgo
that is larg e, heavy, bulky, long o r flat
will have a g reater negative influence on
the vehicle's aerodynamics, center of
gravity and overal l handling. Always
dr ive slowly, avo id sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maxim um permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of your vehi­ cle ¢
page 265, Weights.
@ For the sake of the env ironment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
us ing fuel unnecessarily . So
remove the
r oof rack after using it .

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

- 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
warm up. Begin driving immediately. This
reduces unnecessary emissions.

forth slightly to release the steer ing
wheel lock.
-After starting a cold engine, there may be a brief period of increased no ise 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 battery is disconnected and recon­
nected, you have to hold t he ignition key

Adaptive cruise control
Description

)
Fig. 73 Detect ion range
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¢
page 82.
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
miss ion*: Within the limits of the system,
adap tive cr uise control ca n bra ke in stop-and­
go traffic until t he vehi cle is station ary and
then begin driving again under cer tain condi­
tions ¢

When approaching an object detected ahead,
the adaptive cruise control system brakes to
