Light sensors located in the inside mirror housing and stem
constantly check the light conditions surrounding the vehicle. If
am bie nt brightness falls below a facto ry set value (e.g. wh en driv ing
into a tunnel), the head -and tai llights inc luding the license p late
ill um inat ion are automatica lly t urn ed on. When ambient br ightness
increases again, the external lights are turned off again~&.
Light sens or malfunction
If there is a light sensor malfunct ion, the symbol comes on in the
display . For sa fety reasons, the low beams are turned on perma­
nent ly with the switch in
AUTO . However, you can continue to turn
the lights on and o ff using the light swi tch . Have the light sensor
checked as soon as possible at a dealership .
& WARNING
• Automatic head- and taillight control is only intended to ass ist
the driver . This feature doe s not relieve the dr iver of hi s re spon si­
bil ity to check the headlights and to turn them on manually
ac cording to the current light and vi sibility conditions. For
e x ample , fog and rain cannot be detected by the light sensors .
Con sequently , always switch the headlights
io on under thes e
weather conditions and when driving
in the dark .
• Crashe s can happen when you cannot see the road ahead and
when you cannot be seen by other motor ists .
• Alway s turn on the headlights so that you can see ahead and
so that others can see your car from the ba ck .
[ i ] Tips

t ion is turned o ff. The remaining lights are turned o ff when the key
is taken out of the ignition lock. _.,

• Do not attach stickers to the windshie ld in front of the sensors as
this can disable the automatic head -and tail light control and the
automatic glare -dimming of the rearview mirror(s) .
• Always o bserve the spec ific loca l regu la tions f or your area when
to use your lights .
• I n the event of a light sensor mal function, the d river informa tion
display will show the symbol . If a light sensor malfunct ion is indi ­
ca te d , you must use the ligh t switch to turn the low beams on and

Be aware of the followin g difference be tween
models built to US o r Canadian specifications :
• USA models : illumination of the in strument cluster (gauges and
needles), dash and center console around the gearshift lever is
controlled by a light sensor located in the instrument panel. The
instrument panel illum ination will automatically 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 d river , to
s witch on the headlight s before it gets too dark.
• Canada models : instrument panel illum ination will stay br ight
regardle ss of the inten sity of ambient light . Always be aware of
c hanges in outside light conditions while you are driving . Respond
in time to fading dayli ght by turning the light switch to position
iD

T he windshield wiper lever :::::> fig. 72 has the following posi­
tions:
One -touch wiping
Move the lever to position G), when you want to wipe the
windshield
briefly.
Intermittent wiping ~ l (activating rain sensor)*
Move the lever up to position 0-
- Move the interval set switch@, to change the inter vals .
Low wiper speed
-Move the lever up to position ©-
High wiper speed
- Move the lever up to position @.

- Pull the lever to position© (toward the steering wheel)
and hold.
- Re lease the lever . The washer stops and the wipers keep
going for about four seconds .
Turning off the wipers
-Move the lever back to position @.
The windshield wipers and washer only work when the ignition is
turned on. If you switch off the ignition with th e windshield wiper
lever still in the interval wipe position and then come back a while
later and drive off, the rain sensor will reactivate itse lf after the
vehic le speed has exceeded 4 mph (6 km/h).
The rain sensor* is only activated with the wiper lever set to posi­
tion
G) . 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 sensi tivity, the faster the sensor will react when it senses mois­
ture on the windshield. The pauses between wiper turns depend not
only on the sensitivity setting , but on the vehicle speed as well.
During brief stops , e.g. at a r ed light, wiper mot ion wil l automati ­
cally be reduced to the next lower speed. Wipers a lready turning at
low speed . change to intermittent wip ing.
When the igni tion is turned on, the washer jets are heated.
& 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~

Calibrating the compass
The compass has to be recalibrated if the display is wrong
or inaccurate.
- Hold the@ button down until the letter C is displayed on
the interior rear view mirror.
- Drive in a circle at a speed of about 5 mph (10 km/h) until
a direction is shown on the interior rear view mirror.

Seats and storage
General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
maximum protection if the front seats are correctly
adjusted.
There are various ways of adjusting the front seats to provide safe
and comfortable support for the driver and the front passenger.
Adjust your seat properly so that:
• you can easily and quickly reach all the switches and controls in
the instrument panel
• your body is properly supported thus reducing physical stress
and fatigue
• the safety belts and airbag system can offer maximum protec­
tion
~ page 146.
In the following sections, you will see exactly how you can best
adjust your seats.
There are special regulations and instructions for installing a child safety seat on the front passenger's seat. Always heed the informa ­
tion regarding child safety provided in~
page 168, "Child Safety".
& WARNING
Incorrect seating position of the driver and all other passengers
can result in serious personal injury.
• Always keep your feet on the floor when the vehicle is in motion
- never put your feet on top of the instrument panel, out of the
window or on top of the seat cushion! This applies especially to
the passengers. If your seating position is incorrect you increase
the risk of injury in the case of sudden braking or an accident. If
Controls and equip ­
ment
Seats and storage
& WARNING (continued)
the airbag inflates and the seating position is incorrect this could
result in personal injury or even death.
• It is important for both the driver and front passenger to keep
a distance of at least 10 inches (25 cml between themselves and
the steering wheel and/or instrument panel. If you're sitting any closer than this, the airbag system cannot protect you properly. In
addition to this, the front seats and head restraints must be
adjusted to your body height so that they can give you maximum
protection.
• Always try to keep as much distance as possible between your­
self and the steering wheel or instrument panel.
• Do not adjust the driver's or front passenger's seat while the
vehicle is moving. Your seat may move unexpectedly, causing
sudden loss of vehicle control and personal injury. If you adjust
your seat while the vehicle is moving, you are out of position. •
Driver's seat
The correct seat position is important for safe and relaxed
driving.
We recommend that you adjust the driver's seat in the
following manner:
- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your
knee slightly bent:::>
& in "Why is your seat adjustment
so important?".
Adjust the seatback so that when you sit with your back against the seatback, you can still grasp the top of the
steering wheel. _..
