priate setting.
Adjustment settings
The settings correspond roughly to the following load conditions:
Two front occupants, luggage compartment empty
All seats occupied, luggage compartment empty
All seats occupied, luggage compartment loadedDriver only, luggage compartment loaded
Caution
Always adjust the headlights to avoid dazzling oncoming traffic.
Make sure you lower the headlights when the vehicle is carrying a
heavy load.Instrument lighting
The background lighting of the instruments, the centre
console and the display can be adjusted as required.– Briefly press the knob to release it.
– Turn the button clockwise +” to increase the brightness
of the instrument lighting in dark conditions. – Turn the button anti-clockwise -” to reduce the bright-
ness of the instrument lighting in dark conditions.
– Press the knob in again to prevent the setting from being changed unintentionally.
The instrument lighting (dials and needles), the centre console illu-
mination and the illumination of the displays are regulated by a
light sensor incorporated in the instrument cluster. In bright condi-
tions any changes made to the brigh tness of the instrument lighting
have no effect.
Note
The instrument lighting (illumination of dials and needles) is
switched on when the ignition is on and the vehicle's lights are off.
The instrument lighting is dimmed automatically as the daylight
starts to fade; it is switched off completely when the light condi-
tions become very poor. This function is intended to remind the
driver to switch on the dipped-beam headlights in good time when
light conditions become poor.Applies to vehicles: with xenon headlight bulbsDynamic headlight range controlHeadlights with xenon gas-discharge bulbs automatically adapt to
suit the load being carried when the engine is switched on. The
headlights are also automatically adjusted when the vehicle is in
motion (e.g. when accelerating and braking).

is automatically stored and assigned to the remote control key.
If the rear blind was rolled in automatically when reversing and then
the ignition was switched off and on again, the blind will not roll
back out again when you select a forward gear and the speed
exceeds 15 km/h. You will then have to press the button
 on the
centre console to extend the blind again.
The sun blind for the rear window switches off automatically when
it reaches the end position. It can be made to move in the other
direction before it reaches its end position by briefly pressing the
switch a second time. If the ignition is turned off while the blind is
still moving, it continues until it reaches the end position before
switching off.
Note
•
An overload cut-out may be activated if the sun blind is operated
repeatedly. There will then be a short delay before the blind can be
operated again.
•
As the material of the sun blind is less flexible at low tempera-
tures the electric actuator is switched off when the temperature in
the car is below -5°C. The blind can only be operated when the
temperature in the car's interior rises above this level.

Automatic wash and wipe
– Pull the lever to position .
– Release the lever again. The washer will stop and the
wipers will keep running for approximately 4 seconds.
The number of wipe cycles varies according to the length
of time the lever is pulled.
Switching off the wipers
– Move the lever to the "off" position .General notes
The washers and wipers will only work when the ignition is switched
on.
If you stop briefly, e.g. at traffi c lights, the wiper speed will automat-
ically be reduced by one level.
The windscreen washer jets are heated when the ignition is
switched on if the outside temperature is low.
Dribble wipe
About 5 seconds after the wash and wipe cycle has finished, the
windscreen wiper system automatically gives the screen one extra
wipe to remove any dribbles of water.
If you want to deactivate the dribble wipe function while driving,
pull the lever to position again within 10 seconds.
The dribble wipe function will be re-activated the next time the igni-
tion is switched off and on.
Rain sensor*
The rain sensor will only function in the intermittent wipe position.
The intermittent wipe function is activated automatically when it
starts to rain.
Before you reach a road speed of 6 km/h you will have to activate the
rain sensor manually by switching it off and back on again. To reduce the sensitivity level of the rain sensor move control
⇒
page 62, fig. 64 to the left. To increase the sensitivity level of the
rain sensor move the control to the right.
If you have selected a high sensit ivity level for the rain sensor the
windscreen wipers will react sooner to any moisture on the wind-
screen. The wiper intervals in the intermittent wipe setting are also
varied automatically acco rding to the road speed (in addition to the
sensitivity setting).
WARNING
•
Poor visibility can cause accidents. Always ensure that the
wiper blades are in good condition ⇒page 65, “Changing wiper
blades”.
•
The rain sensor is only intended to assist the driver. The driver
is still obliged to manually o perate the windscreen wipers as
required depending on visibility.
•
Do not use water-repellent coatin gs on the windscreen. In bad
visibility conditions such as light rain, low sun or when driving at
night these coatings can cause increased dazzle, which is a
serious safety hazard. Such coatings can also cause the wiper
blades to judder.Caution
•
In icy conditions, always check that the wiper blades are not
frozen to the glass before using the wiper for the first time. If you
switch on the wipers when the wiper blades are frozen to the glass,
this could damage both the wiper blades and the wiper 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 triggering of the wipers and possible damage to the
wiper system.

vated about every five wash and wipe cycles. The headlights are
always washed if you hold the lever for longer than about
2 seconds.
The headlight washer jets come out of the bumper automatically
(under water pressure).
Clean off stubborn dirt (insects, etc.) from the lenses at regular
intervals, for instance when stopping for fuel.
To ensure that the system works properly in winter, keep the nozzle
holders free of snow and remove any ice with a de-icer spray.

Applies to vehicles: with deluxe automatic air conditioner plusAutomatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automatic air recirculation should be
switched on at all times.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirc ulation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the
 button immediately. The automatic air recirculation can switch itself off in certain condi-
tions. If the outside temperature is
less than about +10 °C, the auto-
matic air recirculation will only operate for 30 seconds. If the air
conditioner is switched to the ECON mode, or if the outside temper-
ature is less than about -1 °C, the automatic air recirculation will
only operate for 15 seconds.
Applies to vehicles: with deluxe automatic air conditioner plusSynchronisation
The air conditioner settings can be synchronised for all
passengers.When the synchronisation function is on, the driver's settings are
also applied to the front passenge r or vice versa. Any subsequent
changes to the air conditioner setti ngs (except for the seat heating*)
are also applied to the other occupant.
You can still change the setting on the “synchronised” side (this will
deactivate the synchronisation function).Applies to vehicles: with diesel engineSupplementary heater– Set the Supplementary heater to auto or off .Models with a diesel engine are equipped with a supplementary
heater to help warm up the interior more quickly. At outside temper-
atures below about +5 °C the supp lementary heater is switched on
(and off) automatically when the engine is running, depending on
the coolant temperature, the temperat ure in the vehicle interior and
the temperature the heater is set to.
