twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired, pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to a reduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Clean the brakes after
driving off-road. If you notice grinding noises or a reduction in braking performance, have the
brake system checked at a qualified specialist
workshop immediately. Adapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the conditions of the terrain. Drive carefully. Have
vehicle damage rectified immediately at a quali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.
General notes H
Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section before driving your vehicle off- road. Practise by driving over more gentle off-
road terrain first. The following driving systems are specially
adapted to off-road driving:
R the Offroad drive program (vehicles without
Off-Road Engineering package)
(Y page 228)
R Offroad andOffroad Plus drive programs
(vehicles with Off-Road Engineering package) (Y page 229)
R LOW RANGE offroad gear (vehicles with the
Off-Road Engineering package)
(Y page 230)
R Differential lock (vehicles with the Off-Road
Engineering package) (Y page 230)
R Off-road ABS (Y page 69)
R Off-road 4ETS (Y page 72)
R Off-road ESP ®
(Y page 74)
R AIRMATIC package (vehicle level)
(Y page 196)
R DSR (Downhill Speed Regulation)
(Y page 227)
Observe the following notes:
R Stop the vehicle before driving off-road. If
necessary, select the offroad program
(Y page 229) or shift to the LOW RANGE off-
road gear (Y page 230).
R Select a vehicle level suitable for the off-road
terrain. To avoid damaging the vehicle, ensure
sufficient ground clearance at all times.
R Make sure that items of luggage and loads are
stowed safely and are well secured
(Y page 316).
R Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR (Y page 227).
R Drive slowly and evenly, if necessary at walk-
ing 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 rea-
sons, 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 Take care when turning on an uphill or down-
hill slope or when driving across a slope. The
vehicle could otherwise tip over.
R Always keep the doors, the tailgate and the
sliding sunroof closed while the vehicle is in
motion. Driving

R
Do not stray from marked routes or paths.
R Observe the notes on off-road fording
(Y page 175).
i Information about retrofitting special all-ter-
rain tyres is available from any qualified spe-
cialist 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 sur- faces.
Checklist before off-road driving X
Engine oil level: check the engine oil and top
it up if necessary.
When driving on steep gradients, the oil level must be sufficiently high to ensure a correct
oil supply in the vehicle.
X AdBlue ®
tank (BlueTEC vehicles): check the
level and top up if necessary (Y page 166).
X Tyre-change tool kit: check that the jack is
working and make sure that the wheel
wrench, a robust tow cable and a folding
spade are in the vehicle.
X Wheels and tyres: check the tyre tread
depth and tyre pressure.
X Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tyres.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Wheels: dented or bent wheels can lead to a
loss of tyre pressure and damage to the tyre
bead. Before driving off-road, check the
wheels and replace them if necessary.
Checklist after off-road driving !
If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
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 If the Off-road orOff-road Plus drive pro-
gram is selected: select the Individual,Sport,
Comfort orSlippery drive program
(Y page 155).
X Deactivate the LOW RANGE offroad gear
(Y page 230).
X Deactivate DSR (Y page 227).
X Lower the vehicle level again to a level suita-
ble to the road conditions, e.g. to the normal
level.
X Clean the headlamps and rear lights and
check for damage.
X Clean the front and rear licence plates.
X Clean the wheels and tyres with a water jet
and remove any foreign objects.
X Clean the wheels, wheel arches and the vehi-
cle 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, tyres, brakes, body-
work 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 detect strong vibrations after driving
off-road, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
Driving on sand Observe the following rules when driving on
sand:
R Select the Offroaddrive program (vehicles
without Off-Road Engineering package)
(Y page 228).
R Select the Offroaddrive program (vehicles
with Off-Road Engineering package)
(Y page 229).
R Select a higher vehicle level.
R Avoid high engine speeds.
R Use the left-hand steering wheel gearshift
paddle to shift to a lower gear appropriate to

Important safety notes G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. G
WARNING
If engine oil comes into contact with hot com- ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil does not spill out
over the filler neck. Allow the engine to cool
down and thoroughly clean the components
that have come into contact with engine oil
before you start the engine.
General notes Depending on your driving style, the vehicle
consumes up to 0.8 litres of oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may beinstalled at a different location.
When checking the oil level:
R park the vehicle on a level surface.
R the engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature.
R if the engine is not at normal operating tem-
perature, e.g. if the engine was only started
briefly, wait approximately 30 minute sbefore
carrying out the measurement. Checking the oil level using the oil dip-
stick Example: vehicles with a petrol engine
Example: vehicles with a diesel engine
X Pull dipstick :out of the dipstick tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide tube
to the stop, and take it out again.
If the level is between MIN mark =and MAX
mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark =or
below, top up with 1.0 lof engine oil.
Topping up engine oil H
Environmental note
When topping up the oil, take care not to spill any. If oil enters the soil or waterways, it is
harmful to the environment.
! Use only engine oils and oil filters that are
approved for vehicles with a service system. A list of the engine oils and oil filters that have
been tested and approved in accordance with
Mercedes-Benz Specifications for Service
Products is available at any Mercedes-Benz

ASSYST PLUSMaintenance and care

The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear pat-
tern has formed on the tyres. Front tyres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure that the direction of
rotation is maintained.
Clean the contact surfaces of the wheel and the
brake disc thoroughly every time a wheel is
interchanged. Check the tyre pressure and, if
necessary, restart the tyre pressure loss warn-
ing system or the tyre pressure monitor
(Y page 366). Direction of rotation
Tyres with a specified direction of rotation have additional benefits, e.g. if there is a risk of aqua- planing. These advantages can only be gained if
the tyres are fitted corresponding to the direc-
tion of rotation.
An arrow on the sidewall of the tyre indicates its correct direction of rotation. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the tyres
against oil, grease, petrol and diesel. Fitting a wheel
Preparing the vehicle X
Vehicles with an emergency spare wheel:
when fitting the emergency spare wheel in the
