Vehicles with halogen headlight
system
Have the headlights adjusted by a
workshop.
Vehicles with adaptive forward
lighting
Adapting the aim of the headlight
beam:
1. Pull lever and hold.
2. Switch on ignition.
3. An acoustic signal sounds after approx. 3 seconds.

it gets dark for illumination of the
instrument panel.
The daytime running lights switch off
when the ignition is switched off.
Adaptive forward lighting
Adaptive forward lighting with Bi-
Xenon headlights improves lighting in
curves and increases headlight
range.
Curve lightingThe 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.

Control of the vehicleNever 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.

134Driving and operating
To repeat the starting procedure or to
switch off the engine, press the button again.
Starting the vehicle at low
temperatures
The start of the engine without
additional heaters is possible down to -25 °С for diesel engines and -30 °C
for petrol engines. Required is an engine oil with the correct viscosity,
the correct fuel, performed services
and a sufficiently charged battery.
With temperatures below -30 °C the
automatic transmission and the
manual transmission automated
need a warming phase of approx. 5
minutes. The selector lever must be
in position P respectively N.
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 easily
ignitable surface. The high
temperature of the exhaust system
could ignite the surface.
■ Always apply parking brake without
pressing release button. Apply as
firmly as possible on downhill or
uphill slopes. Depress the foot
brake at the 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 switchingoff 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.
