Lighting
Vehicles with halogen headlight
system
Have the headlights adjusted by
a workshop.
Vehicles with adaptive forward
lighting Adapting the aim of tne headlight
beam:
1.
Pull lever and hold.
2. Switch on ignition.
3. An acoustic signal sounds after approx. 3 seconds.
Control indicator B 3 92. Daytime running lights
With the ignition on and the light
switch set to 7 or AUTO, the parking
lights are switched on. When the
engine is running, headlights
illuminate.
On vehicle without automatic light
control, 9
must be switched on when
it gets dark for illumination of the
intrument panel.
The daytime running lights switch off
when the ignition is switched off.
Adaptive forward lighting
Adaptive forward lighting with Bi-
Xenon headlamps improves lighting
in curves and increases headlight
range. Curve lighting
The light beam pivots based on
steering wheel position and speed.
Motorway lighting
At higher speeds and continuous
straight ahead travel, the beam
automatically raises slightly, thereby
increasing headlight range.

Adjust
the air flow by switching the fan
to the desired speed.

Air conditioning system Additional to the heating and
ventilation system, the air
conditioning system has:
n
= Cooling
4 = Air recirculation Cooling n
Operated with the n button and is
functional only when the engine and
fan are running.
The air condition system cools and
dehumidifies (dries) when outside
temperature
is above a specific level.
Therefore condensation may form
and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel.
Air recirculation system 4
The air recirculation mode is operated
with the 4 button. 9
Warning The exchange of fresh air is
reduced in air recirculation mode.
In
operation without cooling the air
humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the
vehicle occupants to feel drowsy. Air distribution to
l: Air recirculation
is deactivated.
Maximum cooling
Briefly open the windows so that hot
air can disperse quickly.
■ Cooling n on.
■ Air circulation system 4 on,
■ Set air distribution control to M.

Temperature preselection
Set the temperature control to the

For reasons of comfort, change
temperature
only in small increments.
At the end positions, there is no
temperature regulation. The air
conditioning system works with
maximum cooling or heating.
Heating will not be fully effective until
engine has reached its operating
temperature.
Fan speed
In the automatic mode A the fan
speed automatically regulates the air
flow. If required the air flow can be
manually adjusted.
Cooling n
Operated with the n button and is
functional only when the engine and
fan are running.

Climate control
Heated rear window Ü 3 42.
The preselected temperature is
automatically regulated. In the
automatic
mode the fan speed and air
distribution automatically regulate the
air flow.
The system can be manually adapted
by use of air distribution and air flow
controls. Data is shown on the Info-Display.
Setting modifications are briefly
shown in the Info-Display
,
superimposing over the currently
displayed menu. The electronic climate control system
is only fully operational when the
engine is running.
Do not cover the sensor on the
instrument panel for correct
operation.
Automatic mode
Basic setting for maximum comfort:
■
Press AUTO button.
■ Open all air vents.
■ Air conditioning on.
■ Set desired temperature.
Temperature preselection
Temperatures can be set to the
disired value.
For reasons of comfort, change
temperature only in small increments.
If the minimum temperature is set,
Lo appears in the display and the
electronic climate control system runs
at maximum cooling.
If the maximum temperature is set,
Hi appears in the display and the
electronic climate control system runs
at maximum heating. Fan speed
The selected fan speed is indicated
with
x
and the number in the display.
If the fan is switched off the air
conditioning is also deactivated.
To return to automatic mode: Press
AUTO button.
Demisting and defrosting the
windows
Press the V button. V appears in
the display.
Temperature and air distribution are
set automatically and the fan runs at
a high speed.
To return to automatic mode: press
button V or AUTO.
Switch on heated rear window Ü.
Manual settings in climate menu
Climate control system settings can
be changed via the centre control, the

Switch to manual air recirculation as
necessary.
Manual air recirculation mode
The manual air recirculation mode is
operated with the 4 button. 9
Warning The exchange of fresh air is
reduced in air recirculation mode.
In
operation without cooling the air
humidity increases, so the
windows may mist up. The quality
of the passenger compartment air
deteriorates, which may cause the
vehicle occupants to feel drowsy. Air conditioning with the engine
not running
When
ignition is off, the residual heat
or cooling in the system can be used
for climate control in passenger
compartment. Press the AUTO button with the
ignition off. Residual air conditioning
on will appear briefly in the display.
Residual climate control can only
operate
for a limited period of time. To
cancel, press the AUTO button.
Auxiliary heater
Air heater
Quickheat is an electric auxiliary air
heater which warms up the
passenger compartment more
quickly.
Coolant heater
Diesel-engined vehicles have a fuel-
powered auxiliary coolant heater
which warms up the engine coolant
when the engine is running. Air vents
Adjustable air vents
At least one air vent must be open
while
cooling is on in order to prevent
the evaporator from icing up due to
lack of air movement.
Air vents with adjuster wheel To open or close the vent, turn the
adjuster wheel.

125Direct the flow of air by tilting and
swivelling the slats.
Air
vents without adjuster wheel Open slats and adjust direction of air
flow.
To close the vents, direct slats
downwards.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Maintenance
Air intake
The air intakes in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.
Pollen filter
The pollen filter cleans dust, soot,
pollen and spores from the air
entering the vehicle through the air
intake.

Control of the vehicle
Never coast with engine not
running
Many
systems will not function in this
situation (e.g. brake servo unit, power
steering). Driving in this manner is
a danger to yourself and others.
Pedals
To ensure the pedal travel is
uninhibited, there must be no mats in
the area of the pedals. Starting and operating
New vehicle running-in
Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for
a while after the first drive and avoid
inhaling the fumes.
Fuel
and engine oil consumption may
be higher during the running-in
period.
