A WARNING
- Never use dayt ime 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. T hey do not relieve
the driver of his responsibility to check
the headlights and to tu rn them on man­
ually acco rding to the c urrent light and
visibili ty cond itions. For 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 tur n on t he headlights so that
you can see ahead and so that o thers
c a n see yo ur ca r from the ba ck.
- Please obse rve lega l regu lations whe n
us ing the light ing systems descr ibed .
(D Tips
-The light sensor for headlight control is
l ocated in the rear v iew m irror mount .
Do not apply a ny stic kers to the w ind-
Clear vis ion 43
shield in th is area to p revent malfunc ­
tions or fai lures.
- Some exter io r light ing funct ions can be
adjusted in the d river informat ion sys­
tem
~ page 24.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer w ill sound as long as the
dr iver's door is open to rem ind you to
t u rn off the lights.
- Always observe the specific loca l regula ­
tions for your area as to when to use your
lights.
- With automatic headlights, the high­
beam function is also available, but w it h
one restrict ion:
If you have not sw itched
t he high beams back to low beams dur­
ing automatic headlight operation (fo r
example, afte r d riving throug h a tunnel),
only the low be ams come on the next
t ime au tomatic headlights are switched
on. To use the high beams, you firs t have
to pull the high beam lever back and
then push the leve r forward again.
- In coo l or damp weather, the inside of
the headlights, turn signals and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They w ill clear shortly after
sw itching them on. This does not affect
the se rv ice life of t he lig hti ng .
Adaptive light
Applies to veh icles: w ith Adaptive light
When driving around bends, the relevant area
of the road is better illuminated .
Fig. 4 1 Adapt ive li ght w hen driv ing

44 Clear vis ion
The benefit o f adaptive light is that the curve
and the edge of the road are better illuminat­
ed
c::> fig. 41. The adaptive light is controlled
automatically, depend ing on vehicle speed
and steering wheel angle.
When driving around bends, the head lights
are controlled according to steering wheel an ­
g le. So that there is no black area ahead of the
vehicle, the two main beams pivot at different
angles.
@ Tips
The system works above a speed of about
6 mph (10 km/h).

(D Note
The instrument cluster and center console
illumination (gauges and needles) comes
on when you switch on the ignition and the
vehicle headlights are off. Be aware of the
following difference between models built
to US or Canadian specifications :
- USA models: illumination of the instru­
ment cluster (gauges and needles), dash
and center console around the gearshift
lever is controlled by a light sensor locat­
ed in the instrument panel. The instru­
ment panel illumination will automati­
cally become dimmer as the daylight
fades away and eventually will go out
completely when outside light is very low.
This is to remind you, the driver, to
switch on the headlights before it gets
too dark.
- Canada models: instrument panel illumi­
nation will stay brig ht regardless of the
intensity of ambient light. Always be
aware of changes in outside light condi­
tions while you are driving. Respond in
time to fading daylight by turning the
light switch to position fD (or "AUTO" if
your car is equipped with this feature) to
turn on your headlights.
Luggage compartment light
The light is located on the right side of the
luggage compartment.
These lights come on automatically when the
rear lid is opened. The lights turn
off automat­
ically if the lid is left open for more then 10

Ill>

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
r=;, page 51, 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 49
@ 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
