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.

dipstick
When checking the oil level the vehicle
must
be parked on level ground
be at normal operating temperature
have been stationary for at least five
minutes with the engine turned off
To check the engine oil level with the oil
dipstick, do the following:
Open the hood (
page 222).
Pull out oil dipstick1 (
page 226).
Wipe oil dipstick1 clean.
Fully insert oil dipstick1 into the
dipstick guide tube.
Pull out oil dipstick1 again after
approximately three seconds to obtain
accurate reading.
Oil dipstickThe oil level is correct when it is between
the lower (min) and upper (max) mark of
the oil dipstick.
iPerform the engine oil level check with
the dipstick if it cannot be completed
via the speedometer display
(page 225).
In this case we recommend that you
have the system checked at a
Mercedes-Benz Light Truck Center.
iThe engine oil level can be checked by
either the oil dipstick or via the
speedometer display in the instrument
cluster (
page 224). The amount of
engine oil needed is shown more
precisely in the speedometer display.
