46 Getting startedDrivingAfter a cold start the transmission engages
at a higher revolution. This allows the cata-
lytic converter to reach its operating tem-
perature earlier.More information can be found in the “Op-
eration” section (
page 177).
For information on off-road driving, see
Driving instructions (page 186).
Switching on headlamps
The combination switch is on the left of the
steering column.

!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.Warning!
G
It is dangerous to shift the selector lever out
ofP orN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

72 Safety and SecurityDriving and safety systemsBraking
At the instant one of the wheels is about to
lock up, a slight pulsation can be felt in the
brake pedal, indicating that the ABS is in
the regulating mode. 
Keep firm and steady pressure on the
brake pedal while experiencing the pul-
sation.
Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.LOW RANGE– ABS
During off-road driving a special low range
system for the antilock brake system (ABS)
is operational with transmission in LOW
RANGE mode (
page 118).
When applying the service brakes at
speeds below approximately
18 mph (30 km / h), the front wheels are
locked cyclically to shorten the braking
distance (dig in effect). This affects steer-
ing the vehicle.
More information can be found in the
“Practical hints” section (
page 225).
iWith the ABS malfunctioning, the BAS,
EBP ESP and 4-ETS are also switched
off.
Normal driving and braking functions
are still available.
Warning!
G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency be-
yond that afforded by the condition of the
vehicle brakes and tires or the traction af-
forded. The ABS cannot prevent accidents,
including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, atten-
tive, and skillful driver can prevent acci-
dents. The capabilities of an ABS equipped
vehicle must never be exploited in a reck-
less or dangerous manner which could jeop-
ardize the user’s safety or the safety of
others.

73 Safety and Security
Driving and safety systems
BAS
The Brake Assist System (BAS) operates in
emergency situations. If you apply the
brakes very quickly, the BAS automatically
provides full brake boost, thereby poten-
tially reducing braking distance. Apply con-
tinuous full braking pressure until the
emergency braking situation is over. The
ABS will prevent the wheels from locking.
When you release the brake pedal the
brakes function again as normal. The BAS
is then deactivated.
The
¿
warning lamp in the instrument
cluster (page 25) lights up when you
turn the key to position2. It goes out when
the engine is running.
More information can be found in the
“Practical hints” section (
page 225).
4-ETS
The 4-Electronic Traction System (4-ETS)
improves vehicle’s ability to utilize avail-
able traction, especially under slippery
road conditions. The brakes are applied to
the spinning wheel and power is trans-
ferred to the wheel(s) with traction.
The traction control engages at vehicle
speeds up to approximately 24 mph
(40 km / h), and switches off at 50 mph
(80 km / h).
The
{
warning lamp in the instrument
cluster (page 25) lights up when you
turn the key to position2. It goes out when
the engine is running.
The 4-ETS/ESP warning lamp
v
, locat-
ed in the speedometer dial, starts to flash
at any vehicle speed, as soon as the tires
lose traction and the wheels begin to spin.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that af-
forded by the condition of the vehicle brakes
and tires or the traction afforded. The BAS
cannot prevent accidents, including those
resulting from excessive speed in turns, fol-
lowing another vehicle too closely, or aqua-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
ties of a BAS equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.

186 OperationDriving instructionsOff-road driving
Read this chapter carefully before you be-
gin off-road travel.
Familiarize yourself with the vehicle char-
acteristics and gear changing before you
attempt any difficult terrain off-road driv-
ing. 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:


LOW RANGE mode (
page 118)


LOW RANGE – ABS (
page 72)


LOW RANGE – 4-ETS (
page 74)


LOW RANGE – ESP (
page 76)
Off-road driving rules
Engage the LOW RANGE mode before driv-
ing under off-road conditions
(
page 118).
Fasten items being carried as securely as
possible (
page 139).
Warning!
G
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected ob-
stacles 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 (dan-
ger of vehicle rollover). The vehicle might
otherwise rollover. If in doing so the vehicle
begins to show a tendency to roll, immedi-
ately steer into a line of gravity (straight up
or downhill).
Never let the vehicle roll backwards in idle
or when the clutch is disengaged. You may
lose control of the vehicle if you use only the
service brake.
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.
iWe recommend keeping doors, liftgate,
windows, and sliding/pop-up roof*
closed whenever driving in off-road
mode.

225 Practical hints
What to do if …
Problem
Possible cause
Suggested solution
-
The yellow ABS malfunction indi-
cator lamp comes on while driv-
ing.
ABS has detected a malfunction and has
switched off. The BAS, ESP, 4-ETS and EBP
are also switched off.
The brake system is still functioning normally
but without ABS available.

Continue driving with added caution.
Wheels will lock during hard braking
reducing steering capability.

Have the system checked at an autho-
rized Mercedes-Benz Light Truck Cen-
ter as soon as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
When the voltage is above this value
again, the ABS is operational again.
If necessary, have the generator and
the battery checked.
¿
The yellow malfunction indicator
lamp comes on while driving.
The ESP is no longer synchronized following
a voltage supply interuption (e.g. battery dis-
connected or discharged).
Synchronize the ESP:
Turn the steering wheel from stop lim-
it to stop limit.
The indicator lamp goes out.
The charging voltage has fallen below
10 volts. The BAS and ESP have switched off.
When the voltage is above this value
again, the BAS and ESP are operational
again.
If necessary, have the generator and
the battery checked.
