2013 MERCEDES-BENZ G-Class wheel

The following driving systems are specially
adapted to off-road driving:
R
4ETS ( Y page 62)
R Transfer case (Y page 198)
R Differential locks ( Y page 201)
Observe the following notes:
R stop
your vehicle and, if necessary, shift the
transfer case to LOW
RANGE(Y page 199) before driving off-
road.
R AMG vehicles: to shift the transfer case to
LOW RANGE, deactivate the ECO start/
stop function (Y page 142).
R engage the differential locks, if necessary
(Y page 201)
i ABS, 4ETS, ESP ®
and BAS are deactivated
when the differential locks are activated.
This allows the front wheels to lock briefly,
so that these can dig into a loose surface.
However, please note that locked wheels
skid and can no longer steer.
R Check that items of luggage and loads are
stowed safely and are well secured
(Y page 267).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Always keep the engine running and in gear
when driving on a downhill gradient.
R Always keep the engine running and in gear
when driving on a slope.
R Drive slowly and evenly, if necessary at a
walking pace.
R Ensure that the wheels are in contact with
the ground at all times.
R Drive with extreme care on unknown off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route.
R Check the depth of water before fording
rivers and streams.
R When fording, do not stop and do not
switch off the engine. R
Look out for obstacles such as rocks, holes,
tree stumps and furrows.
R Always keep the doors, rear door, side
windows and the sliding sunroof closed
while the vehicle is in motion.
R Switch off cruise control.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
R Drive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
R On sand, drive quickly to overcome the
rolling resistance. Otherwise, the vehicle
could dig itself into the sand.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at
appropriate engine speeds (maximum
3,000 rpm).
R Do not shift the automatic transmission to
transmission position N.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tires is available from any qualified
specialist workshop.
i Do not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle
on such surfaces.
Checklist before driving off-road !
If the engine oil warning lamp lights up
while the vehicle is in motion, stop the
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. Driving tips

X
Engine oil level: check the engine oil level
and add oil if necessary.
Only then does the engine receive enough
oil when the vehicle is standing on a steep
incline.
X Tire-changing tool kit:
check that the jack
is working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
X Wheels and tires: check the tire tread
depth and tire pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Carry a sound spare wheel.
Checklist after driving off-road 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.
X Shift the transfer case to HIGH
RANGE(Y page 199).
X Disengage the differential locks
(Y page 201).
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear license plates.
X Clean the wheels and tires with a water jet
and remove any foreign objects.
X Clean the wheels, tires, wheel housings and
the vehicle underside with a water jet;
check

for any foreign objects and damage.
X Check 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. X
After the trip, examine without fail the
entire

undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.
X After 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.
X If you notice strong vibrations after off-road
driving, check for foreign objects in the
wheels and drive train and, if necessary,
remove them. Foreign objects can disturb
the balance and cause vibrations.
X Test the brakes.
Driving on sand Observe the following rules when driving on
sand:
R
Shift the transfer case to LOW
RANGE(Y page 199).
R Avoid high engine speeds.
R Limit the shift range of the automatic
transmission according to the off-road
conditions.
R Drive quickly to overcome the rolling
resistance.

Otherwise, the vehicle could dig
itself into the sand.
R Drive in the tracks of other vehicles if
possible. Make sure that the ruts are not
too deep, that the sand is firm enough and
that your vehicle has sufficient ground
clearance.
Tire ruts and gravel roads !
Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
Observe the following rules when driving
along

ruts in off-road terrain or on roads with
loose gravel: 166
Driving tips
Driving and parking

R
Shift the transfer case to LOW
RANGE(Y page 199).
R Avoid high engine speeds.
R Observe
the safety notes (Y page 164) and
the general notes (Y page 164) on off-road
driving.
R Restrict the shift range of the automatic
transmission to 1(Y page 150).
R Drive slowly.
R Where ruts are too deep, drive with the
wheels of one side on the center grassy
area, if possible.
Driving over obstacles !
Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers

for guidance when driving over
large obstacles. The passenger should
always keep a safe distance from the
vehicle when doing so in order to avoid
injury as a result of unexpected vehicle
movements. After driving off-road or over
obstacles, check the vehicle for possible
damage, especially to the underbody and
the components of the chassis.
! Drive with particular care when driving
over an obstacle while driving up or down
a steep slope.
The vehicle could otherwise tilt and slide
sideways or tip over. Observe the following rules when driving over
tree stumps, large stones and other
obstacles: R
Observe
the safety notes (Y page 164) and
the general notes (Y page 164) on off-road
driving.
R Shift the transfer case to LOW
RANGE(Y page 199).
R Avoid high engine speeds.
R Restrict the shift range to 1(Y page 150).
R Make sure that you have enough ground
clearance before driving across an
obstacle.
R Drive very slowly.
R Try to drive straight over the center of
obstacles: front wheel first, then rear
wheel. Traveling uphill
Approach/departure angle G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. Driving tips

R
Observe the safety notes (Y page 164) and
the general notes (Y page 164) on off-road
driving.
R Do not drive at an angle on slopes, inclines
or gradients, but instead follow the direct
line of fall. The maximum gradient-climbing
capability of your vehicle is 80%, which
corresponds to an approach/departure
angle of 38°. Note that the vehicle's
gradient-climbing capability depends on
the off-road conditions.
R Before driving on extreme uphill and
downhill gradients, shift the transfer case
to LOW RANGE(Y page 199).
R Engage the differential locks, if necessary
(Y page 201).
R Drive slowly.
R Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance.
R Avoid high engine speeds – drive at an
appropriate engine speed (maximum
3,000 rpm).
R When driving down an incline, make use of
the engine's braking effect. Observe the
engine speed; do not overrev the engine.
i Further information on the maximum
engine speed: ( Y page 210). R
Select a shift range appropriate to the
gradient.
R Before tackling steep downhill gradients,
select shift range 1(Y page 150).
R Always check the brakes after driving off-
road.
i Hill start assist will aid you when pulling
away on a hill.
For

more information, see "Hill start assist"
(Y page 141).
Maximum gradient-climbing capability On good road surfaces the maximum
gradient-climbing

capability of your vehicle is
80%, which corresponds to an approach/
departure angle of 38°. Note that the
vehicle's gradient-climbing capability
depends on the off-road conditions.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
Hilltops When driving on an uphill gradient, reduce
pressure slightly on the accelerator
immediately

before reaching the top of the hill
(do not shift the transmission to position N).
Use the vehicle's own impetus to drive over
the top of the hill.
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 side168

Driving and parking

Driving downhill
R
Before tackling steep downhill gradients,
select shift range 1(Y page 150).
This way you use the engine's braking
effect to reduce the speed. 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 Observe the notes on driving in
mountainous terrain (Y page 168).
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 roll over.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting
(Y page 61) enables repeated, brief,
precise locking of the front wheels, which
leads to the wheels digging into the loose
ground. Note that when the front wheels
are fully braked, they slide easily over the
surface of the ground, making it difficult to
steer. Driving systems
Cruise control
Important safety notes G
WARNING
The brake pedal moves when cruise control
brakes the vehicle. A foot in the area under
the brake pedal could become trapped. The
movement of the pedal, and therefore the
vehicle's

ability to brake, may be restricted by
objects in the area under the brake. There is
a risk of an accident and injury.
Do not place your foot under the brake pedal.
Keep the area under the brake pedal free from
obstructions. If you fail to adapt your driving style, cruise
control can neither reduce the risk of
accident nor override the laws of physics.
Cruise control cannot take account of road,
weather

and traffic conditions. Cruise control
is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed and for braking in good time. Adjust
your driving style to the traffic conditions.
Only engage cruise control when the current
road, weather and traffic conditions permit it
to be done safely. Drive carefully and
maintain a suitable distance to the vehicle in
front.
Do not use cruise control:
R in traffic conditions that do not allow you
to drive at a constant speed, e.g. heavy
traffic, on winding roads or off-road
R on slippery road surfaces. Braking or
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
General notes Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden,
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).
i Cruise control should not be activated
during off-road driving. Driving systems

R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
the HOLD function and secure the vehicle
against rolling away.

! Never tow the vehicle with one axle
raised.

This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! 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 SmartKey to
position 0 or 1 in the ignition. Failure to do
this can cause damage to the drive train or
the brake system.
! A function or performance test should
only be carried out on a two-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficient grip.
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.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
4MATIC when the current road, weather and
traffic conditions permit it to be done safely,
and adapt your driving style accordingly.
Drive carefully and maintain a suitable
distance to the vehicle in front. Driving systems
