Lighting111
However, when driving in countries
where traffic drives on the opposite
side of the road, adjust the headlights to prevent dazzling of oncoming
traffic.
Vehicles with halogen headlight
system
Have the headlights adjusted by a
workshop.
Vehicles with adaptive forward
lightingAdapting the aim of the headlight
beam:
1. Pull lever and hold.
2. Switch on ignition.
3. An acoustic signal sounds after approx. 3 seconds.
Control indicator B 3 93.
Daytime running lights
With the ignition on and the light switch set to 7 or AUTO , the sidelights
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
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 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.
Control indicator B 3 93.

The lever always springs back to its
original position.
If the lever is moved past the
resistance point, the turn signal is
switched on constantly. When the
steering wheel moves back, the turn
signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance

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.
Direct the flow of air by tilting and
swivelling the slats.

Driving and operating127
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 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 theselector 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.

130Driving and operating
On vehicles with Open&Start system,
P flashes in the transmission display
when the ignition is switched off if P is
not engaged or the parking brake is
not applied.
If Sport mode is activated, 1 is
illuminated.
If the Winter programme is activated,
T is illuminated.
Selector leverP=park position, front wheels

parking brake is appliedR=reverse gear, engage only
when vehicle is stationaryN=neutralD=automatic mode with all gears
The selector lever can only be moved out of P or N when the ignition is on
and the foot brake is depressed
(Selector lever lock).
When the selector lever is in N, the
selector lever lock is activated after a
delay and only if the vehicle is
stationary.
When the selector lever is in the P or
N position, control indicator j in the

when the selector lever is locked. If
the selector lever is not in the P
position when the ignition is switched
off, control indicator j and P in the
gear indicator strip flash.
To engage P or R, press the release
button on selector lever.
When position N is selected, press
