& WARNING
Automatic headlights are only intended to assist the driver. They do not relieve the driver of his responsibility to check the head­
lights and to turn them on manually according to the current light
and visibility conditions. For example, fog cannot be detected by
the light sensors. So always switch on the headlights under these
weather conditions and when driving in the dark
tD .
[ i ) Tips
• The light sensor* for headlight control is located in the rear view
mirror mount. You should therefore not apply any stickers to the
windshield in this area in order to prevent malfunctions or failures.
• The sensitivity level for the light sensor* set at the factory can be
changed in the MMI* menu ~
page 55 in the automatic driving
lights function.
• When you remove your key from the ignition while the vehicle's
lights are turned on, a buzzer sounds as long as the driver's door is
open.
• Please obey all laws when using the lighting systems described
here.
• The coming home/leaving home function* is available only with
the switch in the AUTO position. •

0 Note
The instrument cluster and center console illumination (gauges and
needles) comes on when you switch on the ignition and the
vehicle headlights are off
.
Be aware of the following difference between
models built to US or Canadian specifications:
• USA models: illumination of the instrument 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 driver, to
switch on the headlights before it gets too dark.
• Canada models: instrument panel illumination will stay bright
regardless of the intensity of ambient light . Always be aware of
changes in outside light conditions while you are driving. Respond
in time to fading daylight by turning the light switch to position
gD
(or "AUTO" if your car is equipped with this feature) to turn on your
headlights. •

Xenon headlights
After starting the engine, the xenon headlights are automatically
adjusted to the load and angle of the vehicle (for example, during
