71 Safety and Security
Driving and safety systems
Driving and safety systems
In this section you will find information on
the following driving safety systems:

ABS (Antilock Brake System)


BAS (Brake Assist System)


4-ETS (Electronic Traction System)


EBP (Electronic Brake Proportioning)


ESP (Electronic Stability Program)
ABS
The ABS regulates the brake pressure so
that the wheels do not lock during braking.
This allows you to maintain the ability to
steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure.
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.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBP and
4-ETS is only achieved with winter tires
(M + S tires), or snow chains as re-
quired.
Warning!
G
The following factors increase the risk of ac-
cidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
ABS, BAS, ESP and 4-ETS cannot reduce this
risk.
Always adjust your driving style to the pre-
vailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
ABS and significantly reduces braking effec-
tiveness.

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.

75 Safety and Security
Driving and safety systems
ESP
The Electronic Stability Program (ESP)
monitors the vehicle's traction (force of
adhesive friction between the tires and the
road surface) and handling.
The ESP recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting engine output, the ESP works to
stabilize the vehicle.
The 4-ETS/ESP warning lamp
v
in the
speedometer dial flashes when the ESP is
engaged.
The
¿
warning lamp in the instrument
cluster (page 25) and the 4-ETS/ESP
warning lamp
v
in the speedometer
light up when you turn the key to
position2. They go out when the engine is
running.
Warning!
G
Never switch off the ESP when you see the
4-ETS/ESP-warning lamp
v
flashing in
the speedometer dial. In this case proceed
as follows:


While driving off, apply as little throttle
as possible.


While driving ease up on the accelera-
tor.


Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP cannot prevent accidents resulting
from excessive speed.
Warning!
G
The ESP cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded. The ESP
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 ESP equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or
the safety of others.

Drive sensibly – save fuel
Fuel consumption, to a great extent, de-
pends on driving habits and operating con-
ditions.
To save fuel you should:

Keep tires at the recommended infla-
tion pressures


Remove unnecessary loads


Allow engine to warm up under low
load use


Avoid frequent acceleration and decel-
eration


Have all maintenance work performed
at regular intervals by an authorized
Mercedes-Benz Light Truck Center
Fuel consumption is also increased by driv-
ing in cold weather, in stop-and-go traffic,
on short trips and in hilly country.
Drinking and driving
PedalsPower assistance
Warning!
G
Drinking and driving and/or taking drugs
and driving are a very dangerous combina-
tion. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgement.
The possibility of a serious or even fatal ac-
cident is sharply increased when you drink
or take drugs and drive.
Don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking
drugs.
Warning!
G
Keep driver’s foot area clear at all times. Ob-
jects stored in this area may impair pedal
movement.Warning!
G
When the engine is not running, there is no
power assistance for the steering system. In
this case, it is important to keep in mind that
a considerably higher degree of effort is nec-
essary to steer the vehicle.

182 OperationDriving instructionsParking
Tires
Tread wear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and be-
come visible at a tread depth of approxi-
mately
1/16
in (1.5 mm), at which point
the tire is considered worn and should be
replaced.
!Set the parking brake whenever park-
ing or leaving the vehicle. In addition,
move selector lever to positionP.
In addition, when parking on hills, turn
front wheel towards the curb.
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 as a re-
sult of vehicle movement, before
turning off
the engine and leaving the vehicle always:


Keep right foot on brake pedal.


Firmly depress parking brake pedal.


Move the selector lever to positionP.


Slowly release brake pedal.


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


Turn the key to steering lock position0
and remove.


Take the key and lock vehicle when leav-
ing.
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-
tion to an area which is a safe distance from
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.
