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 iver . 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 car from the bac k.
- With the switch in
AUTO front fog lights
ca nnot be t urned on in addition .
- The light sensor fo r headlight contro l is
l ocated in the rear view m irror mount .
Do no t apply any stickers to the w ind- shield in this area to prevent malfunc
­
tions or fa ilures.
- Some exter io r light ing funct ions can be
adjusted in the driver informat ion sys­
tem
~ page 2 7.
- If you remove the ignition from the igni ­
tion lock while the headlights are still
on, a buzzer will so und 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 regula­
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 riving through a tunnel) ,
only the low beams come on the nex t
t ime au tomati c headlights are swi tc h ed
on. To use the high beams, you first have
to pull the high beam lever back and
then push the lever fo rward again.
- In cool 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
switching them on. This does not affect
the se rv ice life of the lighting .
- Frequent use of the coming home/leav ­
ing home function for app roach ing and
depa rting a vehicle parked in the da rk
w ill strain the battery . Thi s ap plies pa r­
tic ular ly if only short distances a re d riven
between stops . Occasionally drive longer
dis tances to make sure the battery is re ­
charged sufficiently.

(D Note
The instrument cluster and center console
ill umination (gauges and need les) comes
on when you switch on the ignition and the
vehicle headlights are off . Be aware of the
follow ing 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 located in the instrument panel.
The instrument panel illumination 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 driv­
er, to switch on the headlights before it
gets too dark.
- Canada models: instrument panel illu·
mination will stay bright regardless of
the intensity of ambient light. Always be aware of changes in outside light
conditions while you are driving. Re­
spond in time to fading daylight by
turning the light switch to position
gD
(or "AUTO " if your car is equipp ed with
th is feature)
to turn on your headlights.

use the headlight f lasher.
(D Note
Do not use the high beam or headlight
flasher if you know that these could be

Depending on outside temperature and vehi­
cle speed, the mirror surfaces are heated until
the ignition is switched off -even if the rotary
knob is no longer in position@.
You are well-advised to fold the exterior mir­
rors in when maneuvering in tight spaces or
when leaving the car parked close to other ve­
hicles.
(D Note
- Cu rved mirror surfaces (convex or spheri­
ca l*) increaseyourf ield of view. Remem­
ber that vehicles or other objects wi ll ap­
pear smaller and farther away than when
seen in a flat mirror. If yo u use this mir­
r or to est imate distances of following ve­
hicles when changing lanes, you could
estima te incorrect ly and cause an acci­
dent.
(D Tips
I f the re should be a malfunction in the
e lec trical system, you can still adjust the
exterior m irrors by pres sing the edge of
the mirror.

trolyte can cause irr itation to the respira­
tory system, especially among people
with asthma or other resp iratory condi­
tions. Get fresh air immediately by leav­ i n g the vehicle o r, if that is not possib le,
open windows and doors all the way.

.. Move the lever to position @, when you
want to w ipe the w indshield
briefly .
Automatic wiper /w asher
.. Pu ll the lever to posit ion ® (toward the
steering wheel) and ho ld.
.. Re lease the lever . The washer stops and the
wipers keep going for about four seconds.

The w indshield wipers and washe r only work
whe n the ignition is turned on . If you switch
off the ignition with the w indshie ld w iper lev ­
er st ill in the interva l wipe position and then
come back a whi le later and drive off, the rai n
senso r will reactivate itsel f 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 automat ically acti ­
vate the intermittent w iping mode.
To reduce the sensitivity of the sensor, move
switch ® down. To increase the sensitivity,
move t he switch up. The h igher you adjust the
sens it ivity, the faster the senso r will react
when it senses mo isture on the windsh ield .
The rain sensor w iper intervals depend on the
sensit ivity sett ing as well as vehicle speed.
D uring brief s tops, wipe r mot io n will adjust in
r elat ion to the amou nt of rain on the w ind­
shield .
Automat ic w iper/was her : To eliminate water
