interior and the ex te rior of the headlight lens .
- With the main beams switched on, the light -emitting area will
be free o f condensation after a short time, however the edges of
the glass may still be fogged .

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~&.

& WARNING
Never use daytime running lights to see where you are going. They

• With the light switch at the O or ;:oo: position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instruments appear well lit, the road ahead of you is not. The
light pattern provided by fog lights alone is not suffic ient for safe
driving in poor light or darknes s. Therefore:
• Always be aware of changes in outside light conditions while

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

headlights. •
Bi-Xenon headlights*
Afte r starting the engi ne, the b i- xeno n headlights are au tomatical ly
adjusted to the load and angle of the vehic le (for example, during

The windshield wiper lever controls both the windshield
wipers and the washer system.

windshield wiper lever
positions
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 @.
Automatic wiper/washer
- 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~
