Be aware of the following d ifference between
mode ls built to US o r Canadian specifications :
• USA models : illumination of the instrument cluster (gauges and
needles), da sh and c enter console around the g earshift lever is
controlled by a light sensor located in the instrument panel. The
instrum ent panel illumination will automat ically become dimmer
as the d aylight fades awa y and eventually will go out completely
when out side light i s very low . Th is is to remind you, the driver , to
switch on the headlights before it gets too dark .

Automatic headlight control*
In the switch position AUTO the automatic headlight control is

In the
AUTO position the low beams are switched off automatically
when the ignition is turned off.

In the event of a light sensor ma lfunct ion, the driver is notified in the
instrument cluster display:
Automatic headlights/automatic wipers defective
For safety reasons the low beams are turned on permanently with t he

& WARNING
• Never use daytime running lights to see where you are going.
They are not bright enough and will 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 driver .
They do not relieve the driver of his respon sibility to check the
headlights and to turn them on manually according to the current
light and visibility conditions. For example, fog and rain cannot be

detected by the light sensors. So always switch on the headlights
under these weather conditions and when driving
in the dark io.
• Crashes can happen when you 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 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 ,
• If you remove the ignition from t he ignition lock whi le the head­
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 . _,,
