adaptive light*
When switched on, adaptive light adapts to
curves in the road depending on the vehicle
speed and the steering angle. This provides
b etter lighting through the curve . The system
operates at speeds between app roximately
6 mph (10 km/h) and 68 mph (110 km/h).
Static cornering light* (vehicles with adaptive
light) - the cornering light switches on at
speeds up to approximately 25 mph (40 km/
h) when a certain steering wheel angle is
reached or when a turn signal is activated. The
area to the side of the vehicle is illuminated
better when turning .
The adaptive light and the co rnering light only
function when the switch is in the AU TO posi­
tion (automatic headlights*) .
A WARNING
--
- Daytime running lights and automatic
headlights* are only intended to assist
the driver . They do not relieve the driver
of his responsibility to check the head­
lights and to turn them on manually ac­
cording to the current light and visibility
conditions. For example, fog cannot be
detected by the light sensors*. So always
switch on the headlights
io under these
weather conditions and when driving in
the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
the headlights so that you can see ahead
and so that others can see your car from
the back.
- Please obey all laws when using the
lighting systems described here.
(D Note
The rear fog lights* should only be turned
on in accordance with traffic regulation, as
the lights are bright for following traffic. ..,.

(D Tips
-The light sensor * for headl ight control is
l ocated in the rear view m irror mount.
You should therefore not apply any st ick­
ers to the windsh ield in this area in order
to prevent malfunctions or failures .
- Some exterior lighting functions can be
adjusted

-When yo u remove you r key from the igni­
tion w hile the vehicle's lights are turned
on, a buzzer sounds as long as the driv­
er's door is open.

the headlights, turn signa ls and tail
li ghts can fog ove r due to the tem pera ­
ture diffe ren ce betw een the inside and
outside. They will clear shor tly after
swi tching t hem on. This d oes not aff ect
the service life of the ligh ting.

wiper intervals, move the switch @to the
left/right. In vehicles with a rain sensor* the
wipers turn on in the rain once the vehicle
speed exceeds approximate ly 2 mph (4 km/h) .
The higher the sensitivity of the rain sensor* is
set (switch @to the right), the earlier the
windshie ld w ipers react to moisture on the
windsh ield . In some models, you can sw itch
rain sensor mode
off and switch intermittent
mode on in the MM I*. Select:
I CAR I funct ion

®-Clean the windshield. To eliminate water
droplets, the windshield wiper performs one
afterwipe operation after several seconds
while driving. You can switch this function
off
by moving the lever to position @within 10
seconds of the afterwipe operat ion. The after­
wipe function is reactivated the next time the
ignition is sw itched on.
Cleaning the headlights* . The headlight wash­
er system* operates only when the headlights
are on. If you move the lever to position @,
the headlights are washed in intervals.
& 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 cond itions.
- The windshield may not be treated with
water-repell ing windshield coating
agents. Unfavorable conditions, such as
wetness, darkness, low sun, can result in increased glare. Wiper blade chatter is
also possib le.
- Properly functioning windsh ield wiper
blades are required for a clear view and
safe driving
i::> page 51, Replacing
windshield wiper blades.
(D Note
- In the case of frost, check whether the
windshield wiper blades are frozen to
the windshield. Switching on the wind­
shield wipers can damage the wiper
blades!
- Prior to using a car wash, the w indshield
w iper system must be sw itched
off (lever
in position @). This helps to prevent un­
intentional switching on and damage to
the windsh ield wiper system. ..,.
