Applies to vehicles: with automatic headlightsAutomatic (sensor-controlled) headlights
If you set the switch to “AUTO”, the headlights will come
on and switch off automatically according to the ambient
light level.The automatic headlight setting only activates the dipped
beam headlights (not the main beam headlights)
⇒page 52.
Activating automatic headlights
– Turn the light switch ⇒fig. 47 to the AUTO position.
Deactivating automatic headlights
– Turn the light switch to position O.The symbol in the switch lights up when the switch is in the AUTO
position.
The dipped beams, side lights, rear lights and number plate lights
come on together when the headlights are switched on automati-
cally.
When you are using the automatic headlights you can also operate
the main beam headlights, however, please note the following: If you activate the main beam headlights while using the automatic
headlights function (e.g. when driving through a tunnel), but do not
deactivate them again, only the dipped beam headlights will come
on the next time the lights are automatically switched on. To be able
to use the main beam headlights again you must first pull the main
beam lever back to the "off" position and then push it forward again
to "on".
The side lights, headlights and rear fog light can still be switched on
manually in the normal way by using the light switch ⇒page 52.
Sensors in the mounting for the interior mirror monitor the ambient
light level. The headlights will be switched on automatically if the
available light drops below a preset value (for instance when driving
through a tunnel, etc.). The headlights switch off again automati-
cally when the light level increases ⇒.
Malfunction of light sensor
If a malfunction should occur in the light sensor, the symbol
 will
light up in the display. For safety reasons, the dipped beam head-
lights will then be switched on permanently when the light switch
is set to the AUTO position. However, you can still switch the lights
on and off in the normal way with the light switch. You should have
the light sensor checked by a qualified workshop as soon as
possible.
WARNING
•
The automatic headlights are only intended to assist the driver.
The driver must always ensure that the headlights are used when
required, and may have to switch them on manually when the light
conditions or visibility are poor. The light sensors are, for example,
not able to detect rain and fog - you should therefore always
switch on the headlights
 in these conditions and when driving
after dark.
•
Observe all relevant statutory requirements when using the
lighting systems described here.

Technical data Coming home function
When the system is activated and it is dark, the coming home func-
tion will illuminate the vehicle and its surroundings by switching on
the dipped headlights, rear lights, engine compartment lighting*
and number plate lights when the driver's door is opened.
The dipped headlights will stay on for about four minutes as long as
one of the doors or the luggage lid is open.
The dipped headlights stay on for about 30 seconds to light up the
area in front of the car after all the doors and the luggage lid have
been closed.
If required, you can set the time interval to between 0 and 60
seconds in the driver information system (Lights menu) ⇒page 24.
Leaving home function
The dipped headlights and the engine compartment lighting* are
switched on when the vehicle is unlocked with the
 button on the
remote control key if the leaving home function is activated in the
menu display ⇒page 24.
The dipped headlights and the engine compartment lighting*
switch off when the driver's door is opened. If the driver's door is not
opened, the dipped headlights and the engine compartment
lighting* will be switched off when the car automatically locks again
⇒page 41.
Note
•
If you always wish to use the coming home / leaving home func-
tion, you can leave it switched on permanently. As the system is
controlled via a light sensor, it will only work in dark conditions.
•
Permanent use of the coming home / leaving home function, in
particular on short journeys, will increase the load on the battery. To
make sure the battery is always sufficiently charged, occasionally
drive longer distances.

The washers and wipers will only work when the ignition is switched
on.
To reduce the sensitivity level of the light sensor/ rain sensor* move
control downwards. To increase the sensitivity level of the light
sensor/ rain sensor move the control upwards. If you have selected
a high sensitivity level for the rain sensor the windscreen wipers will
react sooner to any moisture on the windscreen. The wiper intervals
in the intermittent wipe setting are also varied automatically
according to the road speed (in addition to the sensitivity setting).
If you stop briefly, e.g. at traffic lights, the wiper speed will automat-
ically be reduced by one level.
