Automatic headlight switch* (sensor-controlled)
If you set the light switch to “AUTO”, the headlights will switch
on and switch off automatically according to the ambient light
level.Turning on dipped-beam headlights
– Turn the light switch ⇒fig. 86 to the AUTO position.
Turning off dipped-beam headlights
– Turn the light switch to position O.The symbol on 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 automatically.
When you are using the automatic headlights switch, you can also operate
the main beam headlights, however, please note the following: If you enable the main beam headlights while using the automatic headlights function
during the day
(e.g. when driving through a tunnel), but do not disable 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, fog lights and rear fog light can still be switched
on manually in the normal way by using the lights switch ⇒page 116.
The mirror inside the vehicle is fitted with sensors that measure the ambient
light. The dipped-beam headlights will be switched on automatically if the
available light drops below the factory preset value (for instance when driving
through a tunnel, etc.). The headlights switch off again automatically when
the light level increases ⇒ .
WARNING
•The automatic dipped-beam headlights are only intended to assist the
driver. Automatic dipped-beam headlights do not relieve the driver of his
or her responsibility to control them an d turn off or turn on the lights manu-
ally according to weather or lighting conditions. The light sensors are, for
example, unable to detect rain and fog - you should therefore always switch
on the dipped-beam headlights
 manually in these conditions and when
driving after dark.
•Observe all relevant legal requirements when using the signalling and
lighting systems described here.Note
•If automatic headlight switching is activated, when the ignition is turned
off the dipped-beam headlights are turned off, and when the key is removed
from the ignition the side lights are turned off.•If you have to attach any type of sticker on the windscreen, do not do so
in front of the sensors. Doing so could prevent the automatic dipped-beam

Disabling the functions
– Briefly press the knob ⇒ fig. 87 to release it from its set position.
– Turn the knob to position 0. – Press the knob in again to prevent the setting from being
changed unintentionally.
The coming home and leaving home functions are controlled by light sensors
in the rear view mirror housing. The system will function when the following
requirements are met:•The knob is set to position 1.•The headlights and the ignition are switched off.•Dark conditions; the sensors register little or no light.
Coming home
When the system is enabled and it is dark, the corresponding exterior lights
switch on as soon as the driver's door is opened.
The exterior lights will stay on for up to a maximum of 2 minutes as long as
one of the doors or the tailgate is open.
The exterior lights stay on for about 30 seconds to light up the area in front of
the car after all the doors and the tailgate have been closed.
This time interval is factory-set, but you can have it changed by a specialist
garage to suit your own requirements (max. setting is 60 seconds).
Leaving home
The exterior lights are switched on when the vehicle is unlocked with the
button on the remote control key.
The exterior lights go out when the driver's door is opened or after 60
seconds when the vehicle locks itself again automatically ⇒page 106.WARNING
Before leaving the vehicle, remove the key from the ignition, as the lights
will not go out if the coming home is enabled. This will lead to battery
discharge and vehicle breakdown.

Note•If you always wish to use the coming home and leaving home functions,
you can leave them permanently switched on. As the system is controlled via
a light sensor, it will only work in dark conditions.•Permanent use of the coming home and leaving home functions, particu-
larly on short journeys, will increase the load on the battery. To make sure the
battery is always sufficiently charged, occasionally drive longer distances.•If the fog lights have been switched on by the coming home and leaving
home functions, they will always be switched off when you switch on the igni-
tion.•Observe all relevant legal requirements when using the signalling and
lighting systems described here.Instrument lighting

Technical Data
– On vehicles equipped with a rain sensor*, you can move the
switch up and down to set the sensitivity of the rain sensor.
Slow wipe
– Move the lever up to position .
Continuous wipe
– Move the lever up to position .
Automatic wash and wipe
– Pull the lever towards the steering wheel, , to activate the windscreen washer.
– Release the lever. The washer will stop and the wipers will keep running for approximately 4 seconds.
Disabling the windscreen wiper
– Pull the lever to basic position .General notes
The washers and wipers will work only when the ignition is switched on.
If you stop briefly, e.g. at traffic lights, the wiper speed will automatically be
reduced. The rain sensor* will automatically be set to the intermittent wipe
function.
The windscreen washer jets are heated when the ignition is switched on.
The wiper intervals in the intermittent wipe setting are also varied automati-
cally according to the road speed (in addition to the manual delay setting).
When the lights are switched on you should only pull the lever briefly to wash
the windscreen, otherwise the headlight washers* will also be enabled. This
will use an unnecessary amount of fluid from the reservoir. Rain sensor
The rain sensor* will only function in the intermittent wipe position. The inter-
mittent wipe function is enabled automatically when it starts to rain.
Before you reach a road speed of 6 km/h ,you will have to enable the rain
sensor manually by switching it off and back on again.
Use control to set the sensitivity of the rain sensor*.
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 automati-
cally according to the road speed (in addition to the sensitivity setting).
WARNING
•For correct visibility and safe driving, the wiper must be in perfect
condition ⇒page 215. Failure to do so could result in an accident.•The rain sensor* is only intended to assist the driver. The driver is still
obliged to manually operate the windscreen wipers as required depending
on visibility.•Do not use water-repellent coatings on the windscreen. In bad visibility
conditions such as light rain, low sun or when driving at night, these coat-
ings can cause increased dazzle, which is a serious safety hazard. Such
coatings can also cause the wiper blades to judder.Caution
•In the event of frost, check that the wiper blade has not frozen before
enabling the windscreen wipers. Should the windscreen wiper system be
enabled when the blade is frozen, this could damage it or even the wind-
screen wiper system motor.•Make sure you switch off the windscreen wiper system (lever in position
0) before you use an automatic car wash. This will avoid inadvertent trig-
gering of the wipers and possible damage to the wiper system.

lights are switched on and off automatically according to the ambient light
level with the aid of the sensors located in the interior rear view mirror
⇒ page 117.WARNING
Electrolyte fluid can leak from a broken mirror. This fluid can cause irrita-
tion to the skin, eyes and respiratory organs. Wash thoroughly with clean
water should you come into contact with this fluid. Seek medical assist-
ance if needed!
Caution
Electrolyte fluid leaking from a broken mirror can cause damage to plastic
surfaces. Use a sponge or similar to remove the fluid as soon as possible.

erly if the sun blind* for the rear window is retracted and if there are no other
objects preventing light from reaching the interior mirror.•If you have to stick any type of sticker on the windscreen, do not do so in
front of the sensors. Doing so could prevent the automatic headlight or anti-
dazzle function from working correctly or even from working at all.Exterior mirrors
