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 Off-road drive program, which assists you
when driving off-road
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 235). 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 acci-
dent 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 dynamometer.
When doing this, turn the key to position
0 or 1in the ignition. Failure to do this can Controls

cause damage to the drive train or the
brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. DSR (Downhill Speed Regulation)
You will find information about driving off-
road in the "Operation" section
(Y page 235).
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
set on the on-board computer (Y page 134).
The steeper the downhill gradient, the greater
the DSR braking effect on the vehicle. When
driving on flat stretches of road or on an uphill
gradient, the DSR braking effect is minimal or
non-existent. G
Risk of accident
DSR is only an aid designed to assist you
when driving downhill. You are responsible
for keeping control of the vehicle and for assessing whether the downhill gradient
can be managed.
When activating DSR the vehicle may brake
suddenly due to DSR intervening. This is
dependent on the downhill gradient and the
difference between the current speed and
the speed set. DSR may not always be able
to keep to the set speed, depending on road
surface and tyre conditions. You could lose
control of the vehicle and cause an acci-
dent.
Select a set speed suitable for the prevail-
ing conditions and when necessary, apply
the brakes manually.
DSR controls the vehicle's speed when
DIRECT SELECT selector lever positions D,
R and Nare selected. You can drive at a
higher or a lower speed than that set on the
on-board computer at any time by braking or
accelerating. G
Risk of accident
If you depress the accelerator pedal with
DSR activated, then the set speed can be
exceeded. Drive downhill with special care
and always keep in mind that DSR brakes
the vehicle as soon as you remove your foot
from the accelerator pedal. The vehicle may
be heavily braked by DSR depending on the gradient and the difference between the
vehicle's road speed and the set speed. You
could lose control of the vehicle and cause
an accident.
The speed is set to 6 km/h at the factory.
Activating/deactivating DSR Activating
You can only activate DSR when driving at a
speeds below 30 km/h.

Only vehicles without the Off-Road Pro engi-
neering package* feature the off-road drive
program.
The off-road drive program assists you in driv-
ing off-road and when fording. The engine's
performance characteristics and the gear-
shifting characteristics of the automatic
transmission are adapted for this purpose.
ABS, ESP ®
and 4 ETS programs especially
adapted to off-road driving are also activated.
Do not use the off-road drive program on
roads that are snowy or icy or if you have fit-
ted your vehicle with snow chains.

drive program using the on-board computer

Only vehicles equipped with the Off-Road Pro
engineering package* feature the LOW
RANGE off-road gear.
The LOW RANGE off-road gear assists you in
driving off-road and when fording. When LOW
RANGE is engaged, the engine's performance
characteristics and the gearshifting charac-
teristics of the automatic transmission are
adapted for this purpose. ABS, ESP ®
and
4 ETS programs especially adapted to off-
road driving are also activated. You will find
information about driving off-road in the
"Operation" section (Y page 235). You will

If you do not wait for the gear change proc-

Differential locks improve the vehicle’s trac-

If your vehicle is equipped with the Off-Road
Pro engineering package*, it is fitted with:
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.

Risk of accident
When driving on a firm road surface, only
drive in AUTO 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 accident thereby increased.
Do not manually engage or disengage the
differential locks while cornering. The vehi-
cle 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 AUTO mode is insufficient.
At speeds of up to 30 km/ h,you can engage
the differential locks in this order: 3, then
4. X

X Turn selector wheel 1to desired position

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 AUTO 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 seconds,
the differential locks switch back to AUTO
mode. Message in the multi-function display
