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.

Notes on these featur es
- The turn signals only work with t he ignition
switched on. The indicator lights
B or IN in
the instrument cluster¢
page 13 also b link.
- After yo u have turned a corner, the turn sig-
nal switches off a utomatica lly.
- The
high beam works only when the head­
lights are on. The indicato r light
II in the
instrument cluster illuminates when the
high beams a re on.
- The
headlight flasher wo rks only as long as
you hold the lever -even if there are no
lights switched on. The indicator light
II in
the instrument cluster illuminates when you
use the headlight f lasher.
(D Note
Do not use the high beam or headlight
flasher if you know that these could be
blind ing oncoming traffic.
