244 Operation
In the “Operation” section you will find
detailed information on operating, main-
taining and caring for your vehicle.
The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle
during the break-in period, the more satis-
fied you will be with its performance later
on.

Drive your vehicle during the first
1 000 miles (1 500 km) at varying but
moderate vehicle and engine speeds.

During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds (no more than
2/3 of
maximum rpm in each gear).

Shift gears in a timely manner.

Avoid accelerating by kick-down.

Do not attempt to slow the vehicle
down by shifting to a lower gear using
the gear selector lever.

Select gear ranges3, 2, or1
(
page 167) only when driving at
moderate speeds (for hill driving).
After 1 000 miles (1 500 km) you may
gradually increase vehicle and engine
speeds to the permissible maximum.All of the above instructions, as may apply
to your vehicle type, also apply when
driving the first 1 000 miles (1 500 km)
after the engine, the transfer case, the
front differential or the rear differential has
been replaced.
!Additional instructions for AMG vehicles:

During the first 1 000 miles (1 500 km), do
not exceed a speed of 85 mph (140 km/h).

During this period, avoid engine speeds
above 4 500 rpm in each gear.
iG55AMG:
For better protection of the front and rear differ-
ential, the oil must be changed after a break-in
period of 1 900 miles (3 000 km).
Changing the oil in the front and rear differential
increases the service life and helps reduce noise
from the differential locks.
See Maintenance Booklet for additional infor-
mation and Factory Approved Service Products
pamphlet (USA only) for information on the
approved service product required to perform
the front and rear axle oil change.
iAlways obey applicable speed limits.

247 Operation
Driving instructions
Refer to the description of the Brake Assist
System (BAS) (
page 90).
Brake pad wear or a leak in the system may
be the reason for low brake fluid in the
reservoir.
The brake fluid level in the reservoir may
be too low if the brake warning lamp in the
instrument cluster comes on although the
parking brake is released (
page 326).
Observe additional messages in the
multifunction display that may appear
(
page 338).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Light Truck Center.
All checks and service work on the brake
system should be carried out by qualified
technicians only. Contact an authorized
Mercedes-Benz Light Truck Center.
Only install brake pads and brake fluid
recommended by Mercedes-Benz.After hard braking, it is advisable to drive
on for some time, rather than immediately
park, so the air stream will cool down the
brakes faster.
Driving off
Apply the brakes to test them briefly after
driving off. Perform this procedure only
when the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the
operating temperature has been reached.
To ensure sufficient traction during
off-road driving, activate differential locks
as needed (
page 175).
Warning!G
If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that
safe braking is substantially impaired. This
could result in an accident.
!When driving down long and steep grades,
relieve the load on the brakes by shifting into a
lower gear to use the engine’s braking power.
This helps prevent overheating of the brakes and
reduces brake pad wear.
!When driving off on a slippery surface, do
not allow a drive wheel to spin for an extended
period with the ESP
® switched off. Doing so may
cause serious damage to the drivetrain which is
not covered by the Mercedes-Benz Limited
Warranty.
!Simultaneously depressing the accelerator
pedal and applying the brake reduces engine
performance and causes premature brake and
drivetrain wear.

Driving instructions
ParkingTires
Warning!G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.

Pull the parking brake lever up as many
notches as possible.

Move the gear selector lever to park
positionP.

Slowly release brake pedal.

When parked on an incline, turn front
wheel towards the road curb.

Turn the SmartKey in the starter switch
to position0 and remove the SmartKey
from the starter switch.

Take the SmartKey with you and lock
vehicle when leaving.
Warning!G
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-
ti o n t o an a r ea wh ic h is a s a fe d is ta n c e fr o m
the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.

253 Operation
Driving instructions
Off-road driving
Read this chapter carefully before you
begin off-road travel.
Familiarize yourself with the vehicle
characteristics and gear changing before
you attempt any difficult terrain off-road
driving. We recommend that you start out
with easy off-road travel.Special driving features for off-road
driving
The following driving features are available
for specific kind of operation:

ABS (page 88)

ESP® (page 92)

4-ETS (page 91)

Differential lock (page 173)

Transfer case (page 170)
Off-road driving rules
Engage the transfer case in position
LOW before driving under off-road
conditions (
page 170).
If necessary activate differential locks
(
page 175).
The ABS, BAS and ESP
® are switched
off automatically when the differential
locks are activated.
Fasten items being carried as securely
as possible (
page 208).
Warning!G
Do not load items on the roof. It may cause
instability during some maneuvers which
could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected
obstacles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehi-
cle cannot complete the attempted climb,
back it down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing
so the vehicle begins to show a tendency to
roll, immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you
use only the brake. For information on
driving downhill, see “Driving downhill”
(
page 257).
Warning!G
Sand, dirt, mud and other material having
friction property can cause exceptional wear
and tear as well as brake failure.
Have the brakes checked for dirt build-up
and cleaned. There is otherwise a risk that
full braking power may not be available in an
emergency.

257 Operation
Driving instructions
Driving across a hilltop
Decelerate just ahead of a hilltop (do not
select gear rangeN), to prevent the
vehicle from speeding up too much after
climbing a hill.
Use the momentum of the vehicle to drive
across the hilltop.
After climbing a hill, driving in this manner
prevents the vehicle from:

loosing ground contact when cresting
hills

loosing its forward momentum

speeding up too much after climbing
the hillDriving downhill

Select gear range1 on the automatic
transmission (
page 167).

Drive downhill observing the same
rules as driving uphill (
page 255).Driving through water
1Fording depth, 19.6 in (50 cm)

Before driving through water,
determine its depth.
!Only apply the service brake if the vehicle is
travelling straight downhill, i.e. in the line of
gravity.
iThe special LOW RANGE – ABS setting
allows for precise and brief (cyclical) blocking of
the front wheels, permitting them to dig into
loose ground.
Remember that, when stopped, the front wheels
slide across a surface and thus lose their ability
to steer the vehicle.
!The water depth must not exceed 19.6 in
(50 cm). The ground under the water might not
be firm which could result the water being
deeper than expected when driving the vehicle
through it. Please note that the water level is
correspondingly lower for flowing water.

260 Operation
Driving instructions

Check the vehicle clearance before
driving in ruts.

Comply with the warnings
(
page 253) and rules for off-road
driving (
page 253).

Select gear range1 on the automatic
transmission (
page 167).

Drive slowly 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.Returning from off-road drivingOff-road driving increases strain on the
vehicle.
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 170).

Switch differential locks off
(
page 176).

Clean all exterior lamps and check
them for possible damage.

Clean the front and rear license plate.

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.
After off-road driving or crossing obstacles,
inspect vehicle for any damage, especially
vehicle underbody and suspension components.
Failure to do so can adversely affect the vehi-
cle’s future performance, including increased
chance of an accident.
Warning!G
Never drive on pavement with activated
differential locks. Engaged front axle differ-
ential 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
appear unsafe, have it towed to the nearest
Mercedes-Benz Light Truck Center or tire
dealer for repairs.
Damage to the vehicle may influence driving
comfort and poses the risk of accident to
you and other drivers.
