A WARNING
- Never use daytime running lights to see
where you are going. They are not bright
enough and w ill not let you see far
enough ahead for safety, especially at
dusk or when it is dark. Always switch on
the low beams at dusk or when it is dark.
- Automatic headlights are only intended
to assist the dr ive r. They do not relieve
the driver of his responsibility to check
the headlights and to tu rn them on man­
ually according to the current light and
visibili ty cond itions. Fo r example, fog
and rain cannot be detected by the light
sensors . So a lways switch on the head­
lights under these weather cond itions
and when driving in the dark
io.
- Crashes can happen when yo u 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 tha t others
can see yo ur ca r from the bac k.
- With the switch in
AUTO front fog lights
ca nnot be t urned on in addition .
- The light sensor for headlight control is
l ocated in the rear view m irror mount .
Do no t apply a ny stickers to the w ind- shield in this area to prevent malfunc
­
tions or fa ilures.
- Some exter io r li ght ing funct ions can be
adjusted in the driver informat ion sys­
tem
~ page 21.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer wi ll sound as long as the
dr iver's door is open to rem ind you to
turn off the lights.
- Always observe the specif ic loca l regu la­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam funct ion is also available, but wit h
one restrict ion: If you have not switched
the high beams back to low beams dur­
ing automatic headlight operation (fo r
example, after d rivi ng through a tunnel) ,
only the low beams come on the nex t
t ime au tomatic headlights are swi tched
on. To use the high beams, you first have
to pull the high beam lever back and
then push the lever forward again.
- In cool or damp weather, the inside of
the headlig hts, turn signals and tail
lights can fog over due to the tempera­
t u re difference between the inside and
outside. They w ill clear shortly after
switching them on. This does not affect
the se rv ice life of the lig hting .
Adaptive light
Applies to veh icles: w ith Adapt ive Light
When driving around bends, the relevant area
of the road is better illuminated.
F ig . 59 Adapt ive li ght w hen dr iv in g

The benefit o f adaptive light is that the curve
and the edg e of th e road are better i lluminat­
ed
c::> fig . 59. T he adaptive light is controlled
automatically , depend ing on veh icle speed
and steering wheel ang le.
When driving a round bends, the head lights
are contro lled according to steer ing wheel an ­
g le. So that there is no black area ahead of the
ve hicle, the two main beams pivo t at different
angles.
(D Tips
T he system works above a speed of about
6 mph (10 km/h) .

come back a while later and drive off, the rain
sensor will reactivate itself after the vehicle
speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the
wiper lever set to position(!). When it starts
to rain, the rain sensor will automatically acti­
vate the intermittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity,
move the switch up. The higher you adjust the
sensitivity, the faster the sensor will react
when it senses moisture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting, but on the ve­
hicle speed as well.
During brief stops, e.g . at a red light, wiper
motion will automatically be reduced to the
next lower speed . Wipers already turning at
low speed. change to intermittent wiping.
When the ignition is turned on, the washer
jets are heated .
A WARNING
-Wiper blades are crucial for safe driving!
Only when they are in good condition are
they able to clear the windows properly
to provide uncompromising visibility.
Worn or damaged wiper blades are a
safety hazard ¢
page 63, Replacing
windshield wiper blades!
- The light/rain sensor* is only designed to
assist and support the driver.
It remains
entirely the driver's responsibility to
monitor outside weather conditions and
to manually activate the wipers as soon
as rain or drizzle reduces visibility
through the windshield.
- The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
Clear vision 61
@ Note
In freezing or near freezing conditions:
- Always check that the wiper blades are
not frozen to the glass before you turn
the wipers on. Loosen a wiper blade
which is frozen in place before operating
the wipers to prevent damage to the
wiper blade or the wiper motor.
- Do not use the wipers to clear a frosted
window. Using the wipers as a conven­ ient ice scraper will destroy the wiper
blades .
- Before you take your vehicle to an auto­
matic car wash, make sure you have the
windshield wiper system switched off (lever in position
0), otherwise the wind­
shield wiper system could get damaged
in the car wash if it should suddenly
come on.
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the windshield wipers after the ignition
is switched back on by moving the wind­
shield wiper lever to any position.
- Worn or dirty windshield wiper blades
cause smearing, which can affect the op­
eration of the light/rain sensor*. Check
the condition of your windshield wiper
blades regularly.
-The rain sensor is part of the interval
wiping system. Turning off the ignition
will also deactivate the rain sensor. To re­
activate the sensor, switch off the inter­
val wiping function, then switch it back
on again.
-Applies to vehicles with light/rain sen­
sor: When the wipers are switched on
manually and in rain conditions, the au­
tomatic headlights* turn on¢
