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)


EBB (Electronic Brake Booster)


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 (as long as the
differential locks are not engaged).
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 experi-
encing the pulsation.
iIn winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBB 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
The 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.

76 Safety and SecurityDriving and safety systems
Switching off the ESP
To improve the vehicle's traction, turn off
the ESP in driving situations where it would
be advantageous to have the drive wheels
spin and thus cut into surfaces for better
grip such as:

starting out on slippery surfaces and in
deep snow in conjunction with snow
chains.


sand or gravel.


when driving off-road.
When the ESP is turned off


engine torque is not limited.


the drive wheels can spin.
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.!Driving the vehicle with varied size tires
will cause the wheels to rotate at differ-
ent speeds, possibly causing the ESP to
activate. For this reason, all wheels, in-
cluding the spare wheel, must have the
same tire outside diameter.
!The engine must be shut off when

the parking brake is being tested on
a brake test dynamometer.


the vehicle is being towed with one
axle raised.
Otherwise, the ESP will engage the
brakes and seriously damage the brake
system.
iThe ABS, BAS and ESP are automatical-
ly switched off when the differential
locks are switched on (
page 145).
Warning!
G
The ESP should not be switched off during
normal driving other than in the circum-
stances described below. Disabling of the
system will reduce vehicle stability in stan-
dard driving maneuvers.

202 OperationDriving instructionsWinter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move selector lever to positionN. Try to
keep the vehicle under control by correc-
tive steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal brake effect.
We therefore recommend depressing the
brake pedal periodically when traveling at
length on salt-strewn roads.
This can bring road salt impaired braking
efficiency back to normal. Be very careful
that you carry out these braking maneu-
vers without endangering any other road
users.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed while observing the
safety rules in the previous paragraph.

page 228).
iInformation on driving with snow
chains (
page 229).
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 control loss.
Do not engage the transfer case in position
LOW when driving on ice or packed snow. At
speeds below 18 mph (30 km / h) vehicle
steering is adversely affected by the LOW
RANGE – ABS (
page 72).
Warning!
G
If the vehicle becomes stuck in snow, make
sure that snow is kept clear of the exhaust
pipe and from around the vehicle with the
engine running. Otherwise, deadly carbon
monoxide (CO) gases may enter vehicle in-
terior resulting in unconsciousness and
death.
To assure sufficient fresh air ventilation,
open a window slightly on the side of the ve-
hicle not facing the wind.Warning!
G
The outside temperature indicator is not de-
s i g n e d t o s e r v e a s a n i c e - w a r n i n g d e v i c e a n d
is therefore unsuitable for that purpose. In-
dicated temperatures just above the freez-
ing point do not guarantee that the road
surface is free of ice.

229 Operation
Winter driving
Snow chains
Snow chains should only be driven on
snow-covered roads at speeds not to ex-
ceed 30 mph (50 km/h). Remove chains
as soon as possible when driving on roads
without snow. Observe the following guidelines when us-
ing snow chains:


Chains cannot be mounted on all
wheel/tire combinations.


Chains should only be used on all four
wheels. With only two chains available,
they should be mounted on the rear
wheels. Follow the manufacturer’s
mounting instructions.


Use only snow chains that are ap-
proved by Mercedes-Benz. Your autho-
rized Mercedes-Benz Light Truck
Center will be glad to advise you on this
subject.
iWhen driving with snow chains, you
may wish to deactivate the ESP
(page 76) before setting the vehicle
in motion. This will improve the
vehicle’s traction.
