Driving 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 Antilock Brake System (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
approximately 5 mph (8 km/h) indepen-
dent of road surface conditions (as long as
the differential lock s are not engaged).
Warning!G
The following factors increase the risk of
accidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following another ve hicle too closely
The driving safety syste ms described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driv ing style to the pre-
vailing road and weat her conditions and
keep a safe distance to other road users and
objects on the street.
iIn winter operation, the maximum effective-
ness of the ABS, the BAS, the ESP®, the EBB, and
the 4-ETS is only achieved with winter tires or
snow chains as required.
Warning!G
Do not pump the brak e pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal de feats the purpose of
ABS and significantly reduces braking effec-
tiveness.

For more information, see “Practical hints”
(
page 330).
EBB
The Electronic Brake Booster (EBB)
enhances braking effectiveness by allow-
ing the rear brakes to supply a greater
proportion of the braking
effort in straight
line braking circumstances without a loss
of vehicle stability.
For more information, see the “Practical
hints” section (
page 327).
ESP®
The Electronic Stability Program (ESP®) is
operational as soon as the engine is run-
ning and 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
spinning or if the vehicle starts to skid.
By applying the brakes to the appropriate
wheel and by limiting engine output, the
ESP
® works to stabilize the vehicle.
The ESP® is especially useful while driving
off and on wet or slippery road surfaces.
The ESP
® also stabilizes the vehicle during
braking and steering maneuvers.
The ESP
® warning lamp v in the instru-
ment cluster (
page 26) flashes when the
ESP® is engaged.
The ESP
® warning lamp v comes on
when you switch on ignition (
page 39).
It goes out when the engine is running.
!Operational or performance test must only
be conducted on a two-axle dynamometer. If
such tests are necessary, contact an authorized
Mercedes-Benz Light Truck Center. You could
otherwise seriously damage the brake system or
the transfer case which is not covered by the
Mercedes-Benz Limited Warranty.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position 0 or 1)
when testing the parking brake on a brake test
dynamometer and such testing should be no
longer than 10 seconds.
Active braking action through ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
Warning!G
If the EBB is malfun ctioning, the brake
system is still functionin g. However, the rear
wheels may lock during hard braking, caus-
ing you to lose control over the vehicle and
possibly causing an accident. Adjust your
driving style to the non-operating status of
the EBB.
