Observe the following notes:
R stop the vehicle before you drive off-road and,
if necessary, shift the transfer case to the
LOW RANGE off-road driving position
(Y page 124)
R engage the differential locks if necessary
(Y page 126)
i ABS,4
ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged. This
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

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
slippery or loose surfaces. The HOLD function
cannot hold the vehicle on such surfaces. You can obtain further information aboutr

tsafety notes G
WARNING
If yo umanipulate, bridge or replace afaulty
fuse with afuse of ahigher amperage ,the
electric cables coul dbeoverloaded. This may
result in afire. There is arisk of an accident
and injury.
Always replace faulty fuses with specified new fuses of the correct amperage. The fuses in your vehicle disconnect fault
ycir-
cuits. If afuse blows, all the components in the
circuit and their functions will fail.
Blown fuses must be replaced with fuses of the same rating, which you can recognise by the
colour and fuse rating. The fuse ratings are listed
in the fuse allocation chart (Y page 233).
If the newly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. aMercedes-Benz Service
Centre.
! Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correc tfuse rating for the system concerned.
Otherwise, components or systems could be
damaged.
! Make sure that no moisture can enter the
fuse box when the cover is open.
! When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses. Bef
