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

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.

For three flashes, e. g. when
changing lanes, press the lever until
resistance is felt and then release. Move the lever to the resistance point
and hold for longer indication.
Switch the indicator off manually by

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.

Overrun cut-off
The fuel supply is automatically cut off
during overrun, i.e. when the vehicle
is driven with a gear engaged but
accelerator is released.
Parking
■ Do not park the vehicle on an easy flammable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply hand brake without pressing release button. Apply as
firmly as possible on downhill or
uphill slopes. Depress the foot
brake at same time to reduce
operating force.
■ Switch off the engine and ignition. Turn the steering wheel until the
steering wheel lock engages.
■ If the vehicle is on a level surface or uphill slope, engage first gear or set
the selector lever to P before
switching off the ignition. On an
uphill slope, turn the front wheels
away from the kerb. If the vehicle is on a downhill slope,
engage reverse gear or set the
selector
lever to P before switching
off the ignition. Turn the front
wheels towards the kerb.
■ Lock the vehicle and activate the anti-theft locking system and the
anti-theft alarm system. Engine exhaust
9
Danger Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless
and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The
diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving. The filter
is cleaned by burning off the soot
particles at high temperature. This
process takes place automatically
under set driving conditions and may
take up to 25 minutes. Fuel
