ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the
buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the belt sash. The
belt should not be held during the adjust-
ment. You can switch the belt adjustment on
and off in the on-board computer
(Y page 108).

belts.
For certain countries only: regardless of
whether the driver or the front passenger
already have their seat belt fastened, the
7 seat belt warning lamp lights up for six
seconds after the engine has been started. It
then goes out if both the driver and the front
passenger have fastened their seat belt. i

Intelligent Light System* (bi-xenon
headlamps*) The Intelligent Light System is a system which
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
The bi-xenon headlamps offer enhanced func-
tions to improve illumination of the road sur-
face, e.g. depending on the vehicle speed or
weather conditions. The system includes the
active light function, motorway mode and
extended range foglamps. The system is only
active when it is dark.
You can activate or deactivate the "Intelligent
Light System" using the on-board computer
(Y page 106). Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
driving. This allows you to recognise pedes-
trians, cyclists and animals.
Motorway mode
Motorway mode increases the range of the
beam.
Active:
R
If you are driving at speeds above
110 km/ha nd do not make any large steer-
ing movements for 1000 m.
R If you are driving at speeds above
130 km/h.
Motorway mode remains active unless your
speed drops speeds below 80 km/h.
Not active: if you are driving at speeds below
80 km/h. 82

Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking will then require significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.
X Move the transmission to position P.

If you switch the engine off with the trans-
mission in position Ror D, the automatic
transmission automatically shifts to N.
If you then open the driver's door or the
front-passenger door or remove the key

Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you Transmission

Differential locks improve the vehicle’s trac-
tion.
Your vehicle is equipped with the following:
R A differential lock for the transfer box: this
controls the balance between the front and
rear axles.
R A differential lock for the rear axle: this
controls the balance between the wheels
and the rear axle.
4ETS (Y page 53) controls the compensation
between the wheels and the front axle.
Engaging the differential locks Automatic mode
Use automatic mode
;for all driving situa-
tions, including driving off-road or when ford-
ing.
In automatic mode, the differential locks are
engaged and disengaged according to driving
requirements. This guarantees sufficient trac-
tion for most driving situations with unrestric-
ted vehicle steerability.
X Start the engine.
The differential locks are in automatic
mode. The indicator lamp in selector
wheel :lights up above symbol for auto-
matic mode ;.
Engaging manually G
Risk of accident
When driving on a firm road surface, only drive
in automatic mode, never with manually
engaged differential locks. If differential locks
have been engaged manually, the vehicle's
steerability is greatly impaired and the risk of
an accident thereby increased.
Do not manually engage or disengage the dif-
ferential locks while cornering. The vehicle
motion could otherwise be jerky. You could
lose control of the vehicle as a result and
cause an accident.
Only engage the differential locks manually if
traction in automatic mode is insufficient.
At speeds of up to 30 km/h, you can engage
the differential locks by hand.
X Start the engine.
X Turn selector wheel :to desired position

The differential locks are not controlled auto-

restricted considerably. Drive carefully and
accelerate gently for optimum traction.
You can switch back to automatic mode at
any time. For safety reasons, the differential
locks disengage automatically at speeds
above 50 km/h. If you stop the vehicle and
switch off the ignition for longer than ten sec-
onds, the differential locks switch back to
automatic mode.

X Continue driving.

Overview of driving systems
The vehicle's driving systems are described
on the following pages:
R cruise control, Distronic *and Speedtronic,
which are used to control the speed of the
vehicle
R Adaptive damping system (ADS), for indi-
vidual adjustment of suspension tuning R
level control, for individual adjustment of
ground clearance
R PARKTRONIC*, which assists you in park-
ing and manoeuvring
R reversing camera*, which assists you when
parking and manoeuvring
The ABS, BAS, adaptive brake lights, ESP ®
,
EBV and 4ETS driving safety systems and the
distance warning function* are described in
the "Driving safety systems" section
(Y page 49). Cruise control
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 30 km/h. G
Risk of accident
Cruise control cannot take account of road
and traffic conditions.
Always pay attention to traffic conditions
even when cruise control is activated.
Cruise control is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time. Driving systems

Storing the current speed or calling up
the last stored speed
G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others.
X Briefly pull the cruise control lever towards
you =.
X Remove your foot from the accelerator
pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously
stored speed.
Setting a speed X
Press the cruise control lever to the pres-
sure point, up :for a higher speed or
down ?for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
i Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
Making fine adjustments in 1 km/h
increments X
Briefly press the cruise control lever to the
pressure point, up :for a higher speed or
down ?for a lower speed.
The last speed stored is increased or
reduced. Adjustment in 10 km/h increments X
Briefly press the cruise control lever
beyond the pressure point, up :for a
higher speed or down ?for a lower speed.
The last speed stored is increased or
reduced.
Deactivating cruise control There are several ways to deactivate cruise
control:
X
Briefly press the cruise control lever for-
wards B.
or
X Brake.
or
X Briefly press the cruise control lever in the
direction of arrow A.
