allowst he front wheels to lock briefly, so that
they can dig into aloose surface. However,
please note that locked wheels skid and can
no longer steer.
R Make sure that items of luggage and loads are
stowed safely and are well secured
(Y page 203).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Alwaysk eep the engine running and in gear
when driving on adownhill gradient.
R Alwaysk eep the engine running and in gear
when driving on aslope.
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 Check the depth of water before fording rivers
and streams.
R Watch out for obstacles.
R Alwaysk eep the doors, the rear door, the side
windows and the sliding sunroof closed while
the vehicle is in motion.
R Do not deviate from marked routes.
R Match your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower your speed should be.
R Do not jump with the vehicle. This will inter-
rupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at appropri-
ate engine speeds.
R Alwaysc heck the vehicle for damage after off-
road driving.
Do not use the HOLD function when driving off- road, on steep uphillord ownhill gradients or on

need to be performed more often if the vehicle is operated under arduous conditions or increased
loads, for example:
R regular city driving with frequent intermediate
stops
R if the vehicle is primarily used to travel short
distances
R for frequent operation in mountainous terrain
or on poor road surfaces
R if the engine is often left idling for long periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil filter changed more frequently. The tyres must be
checked more frequently if the vehicle is oper-
ated under increased loads. Further information can be obtained at aqualified specialist work-
shop, e.g. aMercedes-Benz Servic eCentre. Fuel/water separator

WARNING
Interchangin gthe front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions. The whee lbrakes or suspension components
may alsobed amaged. There is arisk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with
atyre pressure mon-
itor, electronic components are located in the wheel.
Tyre-fitting tools should not be appliedint he
area of the valve ,asthis coul ddamage the
electronic components.
Only have tyres changed at aqualified spe-
cialist workshop.
Interchanging front and rear wheels of differing
dimensions can render the genera loperating
permi tinvalid.
Always pay attention to the instructions and
safety notes under "Changing awheel"
(Y page2 43). The wear patterns on the front and rear tyres
diffe
rdepending on the operating conditions.
Interchange the wheels before aclear wear pat-
tern has formed on the tyres. Frontt yres typi-
cally wear more on the shoulders, while rear
tyres wear more in the centre.
On vehicles that have front and rear wheels of
the same size, you can interchange the wheels
every 5,000 to 10,00 0kmd epending 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 awheel is
interchanged. Check the tyre pressure and reac-
tivate the tyre pressure monitor if necessary
(Y page 241). Direction of rotation
Tyres with aspecifie ddirection of rotation have
additional benefits, e.g. if there is ariskofa qua-
planing. You will only gain these benefit sifthe
correc tdirection of rotation is observed.

Never refue lwith petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality .Fuel that does not
conform to EN 590 can leadtoi ncreased wear
as wellasd amage to the engine and exhaust
system. !
Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
Low outside temperatures In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitablef or operation in colder
climatic conditions.
