Overview of off-road driving systems
The systems which are relevant for off-road
driving are explained on the following pages:
R 4MATIC (permanent four-wheel drive), for
optimum traction
R DSR (Downhill Speed Regulation), which
assists you when driving downhill
R LOW RANGE off-road gear for better trac-
tion off-road
R Differential locks for increased traction off-
road
You will find further information about driving
off-road in the "Operation" section
(Y page 188). 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip. G
Risk of accident
4MATIC cannot reduce the risk of an accident
if you drive too fast.
If a drive wheel spins due to insufficient grip:
R only depress the accelerator pedal as far as
necessary when pulling away.
R accelerate less when driving.
R adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the key to position 112

An acoustic warning will also sound. The
gear change process has not been comple-
ted. LOW RANGE is in the neutral position.
There is no connection between the engine
and the drive wheels.
! Do not drive any further, otherwise you
could damage the vehicle's drive train.
XStop the vehicle. Take into account the
road and traffic conditions when doing
this.
X Depress the parking brake.
X Carry out the gear change process
again.
If the gear change process has been
carried out, the Stop vehicle. Apply
parking brake message disappears. Differential locks
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
= or?.
The indicator lamp in selector wheel :
lights up at the corresponding symbol. 116

The engaged differential appears in the multi-
function display:
A
The differential lock for the transfer case
is locked.
The differential locks are not controlled auto-
matically. The steerability of the vehicle is
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.
Message in the multi-function display
Diff. lock system overheated.
Wait briefly
The differential lock system has overheated
and briefly disengaged.
X Continue driving.
The differential locks cool off and are soon
available once again. Driving systems
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
