Driving instructions
Checklist before off-road driving
Engine oil level

Check the engine oil level
(
page 244). The display ENGINE OIL
LEVEL - OK
must appear in the multi-
function display.
Only then can the vehicle obtain a trou-
ble-free oil supply, even on steep gradi-
ents.
Tires

Check the tread depth and maintain
specified tire inflation pressure
(a placard with the recommended tire
inflation pressures is located on the
driver’s door B-pillar (
page 255)).

Check tires for possible damage and
remove foreign objects.

Replace missing valve caps.Rims

Dented or bent rims can cause tire in-
flation pressure loss and damage the
tire beads. For this reason, check and,
if necessary, change rims before driv-
ing 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.

Avoid excessive engine
speeds – drive at moderate engine
speeds (max. 3000 rpm).

Before driving through water, deter-
mine its depth.

Do not stop vehicle while immersed
in water, and do not shut off the en-
gine.

In sandy soil, drive at a steady
speed as allowed by conditions.
This helps overcome the vehicle
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 on slopes with the en-
gine running and the vehicle in
gear.

Inspect the vehicle for possible
damage after each off-road trip.

If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks immediately. Noti-
fy an authorized Mercedes-Benz Light
Truck Center immediately. Do not add
brake fluid as this will not solve the
problem. For more information, see
“Practical hints” (
page 292).
