When driving off-road on steep inclines, you must
make sure that the DEF tank is su fficiently filled.
Therefore, ensure a le vel of at least ten li ters
before off-road driving. When driving off-road and on con
stru ction sites,
sand, mud and water,also mixed with oil, can get
into the brakes. This may lead toare duction in
braking ef fect or total brake failure, also as a
re sult of increased wear. The braking characteris‐
tics will vary depending on the material that has
got into the sy stem. Clean the brakes af ter driv‐
ing off-road. If youth en notice a reduced braking
ef fect or hear scraping noises, ha vethe brake
sy stem checked immediately at a qualified spe‐
cialist workshop. Adjust your driving style to the
ch anged braking characteristics.
Driving off- road or on con stru ction sites increa‐
ses the possibility of vehicle damage which may
in turn lead tothefa ilure of cer tain major assem‐
blies and sy stems. Adapt your driving style to the
off-road driving conditions. Drive carefull y.Ha ve
any vehicle damage rectified at a qualified spe‐
cialist workshop as soon as possible.
When driving on rough cross-country terrain, do
not shift the transmission into the neutral posi‐
tion and do not disengage the clutch. You could
lose control when attem pting tobrake theve hicle
with the service brake. If your vehicle cannot
manage an uphill incline, drive back down in
re ve rsege ar.
When loading your vehicle for off-road driving or
on a construction site, keep theve hicle's center
of gr avity as low as possible.
Checklist before off-road driving R Check the fuel and DEF le vels (/ page163)
and add if necessary (/ page 125).
R Engine: check the oil le vel and add oil if nec‐
essary (/ page 205). Before driving up or
down extreme inclines or slopes, fill th e oil to
th e maximum le vel.
% If
yo u drive up or down extreme inclines or
slopes, the00B2 symbol may appear in the
multifunction displa y.The engine operating
saf ety is not put at risk if you ha vefilled the
engine oil tothe maximum le vel before the
jou rney.
R Vehicle tool kit: check that the jack is work‐
ing (/ page 250).
R Make sure that a lug wrench (/ page 250), a
wo oden underlay forth e jac k,aro bust tow

car ried in theve hicle.
R Tire s and wheels: check the tire tread dep th

R Check the wheels and tires and wheel wells
fo r trapped fore ign objects and remo vethem.
Tr apped fore ign objects can damage the
wheels and tires or may be flung out from the

R Check the underbody for trapped branches or

R Clean the brake discs, brakepads and axle
joints, particularly af ter operation in sand,
mud, grit and gr avel,wa ter or similar lydirty
conditions.
R Check the entire floor assembly, the tires,
wheels, bodywork stru cture, brakes, steering,
suspension and exhaust sy stem for any dam‐
age.
R Check the service brake for operating saf ety,
e.g. car ryout a brake test.
R Ifyo u notice strong vib rations af ter driving
off-road, check the wheels and driv etra in for
