205 Operation
Driving instructions
Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:
LOW RANGE mode (
page 127)
LOW RANGE – ABS (
page 77)
LOW RANGE – 4-ETS (
page 80)
LOW RANGE – ESP (
page 81)
Off-road driving rules
Engage the LOW RANGE mode before driv-
ing under off-road conditions
(
page 127).
Fasten items being carried as securely as
possible (
page 160).Checklist before off-road driving
Engine oil level
Check the engine oil level
(page 224). The display
OIL i.O
must appear via display in the speed-
ometer.
Only then can the vehicle obtain a trou-
ble-free oil supply, even on steep gradi-
ents.
iWe recommend keeping doors, liftgate,
windows, and tilt / sliding sunroof*
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 is 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
the engine running and the vehicle
in gear.
206 OperationDriving instructionsTires
Check the tread depth and maintain
specified tire pressure (see tire pres-
sure label inside the fuel filler flap).
Check tires for possible damage and
remove foreign objects.
Replace missing valve caps.
Rims
Dented or bent rims can cause tire
pressure loss and damage the tire
beads. For this reason, check and, if
necessary, change rims before driving
off-road.
Vehicle tool kit
Check if the vehicle jack is functional.
In all cases take the vehicle tool kit, a
strong tow rope, a shovel and a small
plank (to put under the vehicle jack on
sandy soil) with you.Driving in steep terrain
Slope angle1 25°
226°
Switch to LOW RANGE mode before
starting to drive up or down steep in-
clines (
page 127).
Driving on embankments, slopes and
other steep inclines should only be
done straight up or downhill, i.e. in the
line of gravity. Maximum vehicle climb-
ing ability is a 60% grade.
Do not drive along the side of a slope
(danger of vehicle rollover). If in doing
so the vehicle begins to show a tenden-
cy to roll, immediately steer into a line
of gravity (straight up or downhill).
To help avoid the vehicle rolling over,
never turn it around on steep inclines.
If the vehicle cannot complete the at-
tempted climb, back it down in reverse
gear.
Utilize the engine’s braking power
when descending a slope, observe the
engine speed (do not overrev the en-
gine). Apply the service brake as need-
ed.
Check the brakes after a lengthy down-
grade drive.iAvoid excessive engine speeds – drive
with moderate engine speeds
(max. 3000 RPM).
Select gear range2 or1 on the auto-
matic transmission (
page 122).
227 Operation
Engine compartment
Screw filler cap2 back on filler neck.
For more information on engine oil, see the
“Technical data” section (
page 312) and
(
page 314).
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.
312 Technical dataFuels, coolants, lubricants, etc.Capacities
Vehicle components and their respective
lubricants must match.Therefore only use products tested and
approved by Mercedes-Benz.Please refer to the Factory Approved
Service Products pamphlet, or inquire at
your Mercedes-Benz Light Truck Center.

Measurement for the inner friction (vis-

or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
