GWarning!
Vehicles with air suspension program: Please
be aware that by raising the vehicle level, the
center of gravity also rises. Therefore, always
ensure that the vehicle level is as low as
possible. With higher ride height the ESP ®
may activate earlier in certain situations.
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
General information
Read this section before driving your vehicle
off-road. Practice by traveling over more
gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear change process
before driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
R off-road drive program ( Y page 193)
R off-road ABS ( Y page 66)
R off-road 4ETS ( Y page 67)
R off-road ESP ®
(Y page 68)
R hill start assist
R AIRMATIC package ( Y page 183)
R DSR (Downhill Speed Regulation)
( Y page 192)
Observe the following notes:
R stop your vehicle and, if necessary, select
the off-road drive program ( Y page 193)
before driving off-road.
R vehicles with the AIRMATIC package:
select a vehicle level that is suitable for the
terrain. Make sure there is always sufficient
ground clearance to prevent damage to the
vehicle.
R make sure that items of luggage and cargo
are stowed safely and are well secured
( Y page 260).
R always keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR ( Y page 192).
R always keep the doors, tailgate, windows
and the tilt/sliding sunroof closed while the
vehicle is in motion.
R adapt the speed to suit the terrain
conditions. The more uneven, worn or
steeper the terrain is, the slower you should
drive.
R drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R look out for obstacles, such as rocks, holes,
tree stumps and furrows.
R check the depth of water before fording
rivers and streams.
R do not stop in water and do not switch the
engine off.
R drive quickly on sand to overcome the
rolling resistance. Otherwise, the vehicle
could dig itself into the sand.
R do not jump with the vehicle. This
interrupts the vehicle's traction.
R always keep the engine running and in gear
when driving on slopes.
R do not shift the automatic transmission to
transmission position N.
Check list before driving off-roadXEngine oil level: check the engine oil and
top it up if necessary.
The oil supply can only be guaranteed on
steep slopes if the engine oil level is
sufficient.

vehicle in a safe place as soon as possible.
Check the engine oil level. The engine oil
warning lamp warning must not be ignored.
Continuing the journey while the symbol is
displayed could lead to engine damage.XWheel-changing tool kit: check that the
jack is working and make sure you have the
wheelbrace, a robust tow cable and a
folding spade in the vehicle.XWheels and tires: check the tire tread
depth and tire pressure. A table with the
recommended tire pressures can be found
on the B-pillar on the driver's side of your
vehicle.XCheck for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.XReplace any missing valve caps.XReplace dented or damaged wheels.XWheels: dented or deformed wheels could
result in a loss of tire pressure and damage
the tire bead. Therefore, check the wheels
before driving off-road and replace them if
necessary.
Check list after driving off-road
GWarning
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle appears
unsafe, have the vehicle towed to the nearest
authorized Mercedes-Benz Center or tire
dealer for repairs.
Driving over rough terrain places greater
demands on your vehicle than driving on
normal roads. After driving off-road, check
the vehicle. This allows you to detect damage
promptly and reduce the risk of an accident
to yourself and other road users.
XDeactivate the off-road drive program
( Y page 193).XDeactivate DSR ( Y page 192).XVehicles with the AIRMATIC package: lower
the vehicle to a level that suits the road
conditions, e.g. highway/high-speed level.XClean the headlamps and rear lights and
check for damage.XClean the front and rear license plates.XClean the wheels/tires, wheel arch and the
underbody with a water jet. Check for
damage and remove any foreign objects.XAfter the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.XCheck whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber
bellows of the axle joints and propeller
shafts.XAfter driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.XIf you detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.XTest the brakes.
Driving on sand
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.

Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator
immediately before reaching the brow of the
hill. Make use of the vehicle's own impetus to
travel over the brow.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from traveling too quickly down
the other side
Driving downhill
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and rollover.
R Before tackling steep downhill gradients,
select shift range 1.
R Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line
of fall.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting enables
the front wheels to be locked accurately,
briefly and repeatedly, causing them to dig
into the loose ground. Note that when the
front wheels are fully braked, they slide
easily over the ground surface and
therefore steering is impaired.
Driving abroad
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" section of the Service
Booklet.
Driving systems
Cruise control
Important safety guidelines
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, 2 or 3 in 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.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
GWarning
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

dynamometer, please consult an
authorized Mercedes-Benz Center
beforehand. You could otherwise damage
the drive train or the brake system.
Information on "Off-road driving"; see
( Y page 166).
DSR (Downhill Speed Regulation)
Important safety guidelines
DSR is an aid to assist you when driving
downhill. It keeps the speed of travel at the
speed selected on the on-board computer.
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.
The speed is set to 4 mph (6 km/h) at the
factory; you can adjust this in the on-board
computer ( Y page 219).
GWarning!
Downhill Speed Regulation (DSR) is a
convenience system designed to assist the
driver during vehicle operation. The system
setting must be appropriate to the
topographical and weather conditions
encountered, which can change quickly. The
driver is responsible for the vehicle speed and
for safe brake operation at all times.
Depending on the programmed speed, actual
vehicle speed and gradient, switching on DSR
while driving can cause the vehicle to slow
down rapidly, and you may hear a sound,
caused by the activation of the vehicle's brake
system through DSR. Sudden and unexpected
deceleration can result in loss of vehicle
control, causing an accident and/or serious
personal injury to you and others. Do not
switch on DSR in a situation where rapid
deceleration could result in a loss of vehicle
control.
DSR controls the set speed when it is active
and the automatic transmission is in the D,
R or N position. You can drive at a higher or
a lower speed than that set on the on-board
computer at any time by accelerating or
braking.GWarning!
If you depress the accelerator pedal with DSR
activated, the vehicle can drive faster than the
programmed set speed. You should therefore
drive downhill with particular caution as it
could lead to an accident and/or serious
injury to you or others. Keep in mind that as
soon as you remove your foot from the
accelerator pedal with DSR switched on, DSR
will start regulating the vehicle's speed
including use of brakes if required. Depending
on the programmed set speed, actual vehicle
speed and gradient, DSR can cause the
vehicle to slow down rapidly. Sudden and
unexpected deceleration can result in loss of
vehicle control, causing an accident and/or
serious personal injury to you and others.
Information on "Off-road driving"; see
( Y page 166).

Off-road drive program
General notes
The off-road drive program assists you in
driving off-road. The engine’s performance
characteristics and the gearshifting
characteristics of the automatic transmission
are adapted for this purpose. ABS, ESP ®
and
4ETS 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
mounted snow chains to your vehicle.
Information on "Off-road driving"; see
