219 Operation
The first 1000 miles (1500 km)
All of the above instructions, as may apply
to your vehicle type, also apply when driv-
ing the first 1000 miles (1500 km) after the
engine, the transfer case, the front differ-
ential or the rear differential has been re-
placed.i
G55AMG:
For better protection of the front and
rear differential, the oil must be
changed after a break-in period of
1900 miles (3000 km).
Changing oil in the front and rear
differential increases the service life
and helps reduce noise from the
differential locks.
See Maintenance Booklet for additional
information and Factory Approved
Service Products pamphlet for informa-
tion on the approved service product
required to perform the front and rear
axle oil change.
i
Always obey applicable speed limits.

229 Operation
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.

234 Operation
Driving instructions
Returning from off-road drivingOff-road driving increases strain on the ve-
hicle.
We recommend that you inspect the vehi-
cle for possible damage after each off-road
trip. Recognizing any damage and a subse-
quent timely repair reduces the chance of
a possible breakdown or accident later on.
Proceed as follows:

Switch the transfer case in position
HIGH (
page 157).

Disengage differential locks
(
page 162).

Remove excessive dirt from tires,
wheels, wheel housings, and under-
body.
For instance, after driving in mud, clean
the radiator, chassis, engine, brakes,
and wheels from extreme dirt using a
strong jet of water.

Inspect frame, oil pan, brake hoses,
etc., as well as vehicle underbody for
possible damage.

Check tires for possible damage and
remove foreign objects. Clean all exte-
rior lamps and conduct a brake test.
Warning!G
Never drive on pavement with activated dif-
ferential locks. Engaged front axle differen-
tial locks limits ability to move around
curves.
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning flash-
ers, carefully slow down, and drive with cau-
tion to an area which is a safe distance from
the roadway.
Inspect the tires and under the vehicle for
possible damage. If the vehicle or tires ap-
pear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Damage to the vehicle negatively influences
driving comfort and poses the risk of acci-
dent to you and other drivers.

!
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).
