Driving instructions
Off-road driving rules
Engage the Off-road driving program
(page 248) before driving under
off-road conditions.
If equipped with vehicle level control*,
make sure you select a vehicle level ap-
propriate to the topographical condi-
tions. Always make sure the vehicle
has enough ground clearance.
Fasten items being carried as securely
as possible (
page 259).
Always navigate gradients with the en-
gine on and with the transmission en-
gaged in a gear. Switch on the DSR
(page 245) to help maintain a preset
speed.Checklist before off-road driving
Engine oil level
Check the engine oil level with the
control system (ML 500 only)
(page 328), or with the oil dipstick
(ML 350 only) (
page 330).
Only with a proper oil level can the
vehicle obtain a trouble-free oil supply,
even on steep gradients.
iWe recommend keeping doors, tail-
gate, windows, and tilt/sliding sun-
roof* closed whenever driving in
off-road mode.
!Observe the following during off-road
driving:
Adjust vehicle speed to condition of
terrain. The more uneven, rutty and
steeper the terrain, the lower the
speed should be.
Watch out for obstacles, such as
rocks, holes, tree stumps and ruts.
Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.
Before driving through water, deter-
mine its depth.
Do not stop vehicle while immersed
in water, and do not shut off the
engine.
In sandy soil, please drive at a
steady speed as allowed by condi-
tions. This helps overcome the vehi-
cle rolling resistance and reduces
the likelihood of the vehicle sinking
into the ground.
Do not initiate jumps with the vehi-
cle. It interrupts the forward mo-
mentum of the vehicle.
Always drive onto slopes with the
engine running and the vehicle in
gear.
312 OperationDriving instructionsWhen driving over tree stumps, big rocks
and other obstacles, observe the following
rules:
Make sure the Off-road driving program
(page 248) is switched on.
Avoid high engine speeds.
Select gear range1 on the automatic
transmission (
page 187).
Check the vehicle clearance before
crossing obstacles.
Cross obstacles (e.g. tree stumps or
big rocks) very slowly by aiming one of
the front wheels at the center of the ob-
stacle, and repeat same with the rear
wheel.Driving on sand
For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.
Avoid high engine speeds.
Select the gear range on the automatic
transmission that is appropriate for the
terrain.
In sandy soil, drive at a steady speed as
allowed by conditions. This helps over-
come the vehicle rolling resistance and
reduce the likelihood of the vehicle
sinking into the ground.
Drive in tracks of other vehicles if they
are not too deep and if you have suffi-
cient clearance.
Ruts
A number of off-road tracks or other by-
ways have deep ruts which can cause the
underbody to come in contact with the
ground.
Switch on the Off-road driving program
(page 248).
For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.
Avoid high engine speeds.
Select gear range1 on the automatic
transmission (
page 187).
Drive next to the ruts rather than
through them if at all possible.
If the ruts are too deep to drive in, drive
with one side of the vehicle on the
grassy center strip if the route permits.
!Special attention is needed when you
cross obstacles on a steep incline.
The vehicle could slide sideways as a
result of its possible slanted position
which in turn may result in the vehicle
tipping or rolling over.
!Check that the ruts are not too deep
and your vehicle’s clearance is suffi-
cient. Otherwise:
your vehicle may be damaged.
the underbody of the vehicle may
come in contact with the ground
and you may get stuck.
332 OperationEngine compartment
Unscrew filler cap1 from filler neck.
Add engine oil as required. Be careful
not to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw filler cap1 back on filler neck.
For more information on engine oil, see
“Technical data” (
page 481).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Light
Truck Center check the automatic trans-
mission.Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
!Excess oil must be siphoned or drained
off. It could cause damage to the
engine and catalytic converter not
covered by the Mercedes-Benz Limited
Warranty.
Warning!
G
In order to avoid any possibly serious burns:
Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature gauge indi-
cates that the coolant is overheated.
Do not remove pressure cap on coolant
reservoir if coolant temperature is
above 158°F (70°C). Allow engine to
cool down before removing cap. The
coolant reservoir contains hot fluid and
is under pressure.
Using a rag, slowly open the cap approx-
imately
1/2 turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.
Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.

bars.
Aspect ratio
Dimensional relationship between tire

are 14.5038 pounds per square inch (psi)
to 1 bar; there are 100 kilopascals (kPa)
to 1 bar.
