110Lighting
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 92.
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.

126Driving 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 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.

138Driving and operatingBrakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when you depress the
brake pedal firmly. You need to use
considerably more force for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 88.
Antilock brake system Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency
to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent though a pulse in the brake pedal and the
noise of the regulation process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that
the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs a self-test which may be audible.
Control indicator u 3 88.
Adaptive brake lamp
During full braking, all three brake
lamps flash for the duration of ABS
control.Fault9 Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.

Driving and operating139Parking brake
Always apply parking brake firmly
without operating the release button,
and apply as firmly as possible on a
downhill or uphill slope.
To release the parking brake, pull the lever up slightly, press the release
button and fully lower the lever.
To reduce the operating forces of the
parking brake, depress the foot brake
at the same time.
Control indicator R 3 88.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the
brake pedal for as long as full braking
is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist
The system helps prevent unintended movement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further 2 seconds. The brakes release automatically as soon
as the vehicle begins to accelerate.Ride control systems
Electronic stability
program
Electronic stability program
(ESP® Plus
) improves driving stability
when necessary, regardless of the
type of road surface or tyre grip. It also
prevents the drive wheels from
spinning.
As soon as the vehicle starts to
swerve (understeer/oversteer),
engine output is reduced and the
wheels are braked individually. This
considerably improves the driving
stability of the vehicle on slippery road
surfaces.
ESP® Plus
is operational as soon as
control indicator v extinguishes.
When ESP® Plus
comes into action v
flashes.
