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

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 driver .
They do not relieve the driver of his respon sibility to check the

• Crashes can happen when you cannot see the road ahead and
when you cannot be seen by other motorists.

so that others can see your car from the back.
(I) Tips
• With the switch in AUTO front fog lights cannot be turned on in
addition.
• Th e light senso r for headlight control is located in the rear view
mirror mount . Do not apply any stickers to the windshield in this area
to prevent malfunctions or fail ures .
• Some exterior lighting functions can be adjusted in the driver
information system => page 22 ,

lights are still on, a buzzer will sound as long as the driver's door is
open to remind you to turn off the lights .
• Always observe the specific local regulat ions for your area as to
when to use your lights.
• With automatic headlights, the high-beam funct ion is also avail­
able, but with one restr iction:
If you have not switched the high
beams back to low beams during automatic headlig ht operation (for
example, after driving through a tunnel), only the low beams come
on the next time automatic headlights are switched on . To use the
high beams, you first have to pull the high beam lever back and then
push the lever forwa rd again .
• In cool or damp weather, the inside of the headlights, turn signa ls
and ta il lights can fog over due to the temperature difference
between the inside and outside. They will clear shortly after switching
them on. This does not affect the serv ice life of the light ing . _,,
