or
X Press the % or & button on the
SmartKey.
The alarm is switched off. Tow-away alarm
An audible
and visual alarm is triggered if your
vehicle's angle of inclination is altered while
the tow-away alarm is armed. This occurs if
the vehicle is jacked up on one side, for
example.

the vehicle with the
SmartKey.
The tow-away alarm is deactivated
automatically.
To prevent a false alarm, deactivate the tow-
away alarm manually if your vehicle:
R is being transported
R is being loaded onto a ferry or car
transporter, for example
R is parked on a movable surface, e.g. in a
split-level garage Deactivating:

Safety

R
Avoid high engine speeds. Drive at
appropriate engine speeds (maximum
3000 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
authorized Mercedes-Benz Center. H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Checklist before driving off-road 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.
! 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.
X Wheel-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 G
WARNING
If you notice sudden significant vibrations or
unusual handling performance or if you
suspect that damage has occurred to the
vehicle, you should activate the hazard
warning lamps, gently reduce speed and
carefully head for an area that is located at a
safe distance from the road.
Check the tires and the underside of the
vehicle for damage. If the vehicle seems
unsafe, have the vehicle towed away to the
nearest Mercedes-Benz Center or tire dealer
to be repaired.
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
(Y page 145).
X Disengage the differential locks
(Y page 148).
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 arches 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. 136
Driving tips
Driving and parking

Differential locks
General information Differential locks improve the traction of the
vehicle.
G
WARNING
Never drive on firm road surfaces with
differential locks engaged. Never drive on
narrow bends
with front-axle differential locks
engaged. With differential locks engaged, the
vehicle's ability to steer is severely restricted
and the danger of accidents is therefore
higher.
Do not engage or disengage differential locks
while driving on a bend. The vehicle may
otherwise make a jerking movement. You
could thus lose control of the vehicle and
cause an accident.
If you select a differential lock, ABS, 4ETS,
ESP ®
and BAS will be deactivated.
Your vehicle is equipped with a differential
lock for:
R the transfer case: this controls the balance
between the front and rear axles.
R the rear axle: this controls the balance
between the wheels on the rear axle.
R the front axle: this controls the balance
between the wheels on the front axle.
! In order to avoid damage to the transfer
case, you must operate the vehicle on a
dynamometer (1-axle dynamometer) only
if:
R the axle not driven on is jacked up
or
R the corresponding propeller shaft is
disconnected
and
R the differential lock of the transfer case
is engaged.
Otherwise, the transfer case can be
damaged. Information about differentials and
differential locks When
the vehicle drives around a corner, the
wheels on

the outside of the bend must cover
a greater distance. Therefore, the wheels turn
more rapidly than on the inside. The
differential, a transmission in the drivetrain,
balances out the different rotational speeds
and therefore enables driving through bends.
The disadvantage of a differential is that more
power is transferred to the wheels that have
the least grip. Example: a wheel on a driven
axle stands on snow-covered ground and thus
has no traction. This wheel receives the
strongest driving power from the differential,
as the force progression takes the path of
least resistance. The opposite wheel on this
axle, however, which stands on firm ground
and could therefore allow propulsion,
receives no driving power. 4ETS eliminates
this disadvantage. It provides good
steerability by automatically braking the
spinning wheel. As a result, 4ETS directs
more driving power to the wheel standing on
firm ground, which is therefore able to
provide propulsion.
ESP® and 4ETS are traction systems that are
ideal for road driving and suitable for light off-
road driving. Off-road gear LOW likewise
improves off-road capabilities.
Moreover, the more difficult conditions in off-
road driving require further measures such as
locking one or several differentials. Your
vehicle is equipped with three differential
locks:
R a central differential lock for the transfer
case,
R a differential lock for the front axle and
R a differential lock for the rear axle.
Each differential lock can be engaged with the
respective switch on the center console.
When the central differential lock for the
transfer case is locked, the speed of the front
wheels is equal to that of the rear wheels.
When the differential for the rear axle is
locked, both rear wheels turn equally fast, 148

WARNING
You must remove the spare wheel from the

Otherwise the vehicle could fall off the jack
and injure you or others.

i Vehicles without a spare wheel/
emergency spare wheel are not equipped
with a

tire-change tool kit at the factory. For
more information on which tools are
required to perform a wheel change on your
vehicle e.g. lug wrench or jack, consult an
authorized Mercedes-Benz Center.
Securing the vehicle to prevent it from
rolling away X
Secure
the vehicle to prevent it from rolling
away.
On level ground: place chocks or similar
items under

the front and rear of the wheel that is diagonally opposite to the wheel you
wish to change.
X On downhill gradients: place chocks or
similar items behind both wheels of the
other axle. G
WARNING
Only
jack up the vehicle on level ground or on
slight inclines/declines. The vehicle could
otherwise fall off the jack and injure you or
others.
Raising the vehicle G
WARNING
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The jack

is designed exclusively for jacking up
the vehicle under the axle housing. Make sure
the jack is positioned correctly under the axle
housing. The jack must always be vertical
when in use, especially on inclines or
declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizeable objects before raising the vehicle
with the jack. Do not disengage the parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery Flat tire
