Safety guidelines for the seat belt,
emergency tensioning device and
air bag We caution you not to rely on the
presence of the air bags in order to
avoid wearing your seat belt.
It is important to your safety and that of
your passengers that you replace de-
ployed air bags and repair any malfunc-
tioning air bags to make sure the
vehicle will continue to provide supple-
mental crash protection for occupants.Warning!
G


Damaged seat belts or belts that were
highly stressed in an accident must be
replaced and their anchoring points
must also be checked. Only use belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.


Air bags and pyrotechnic emergency
tensioning devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced. PRE-SAFE* has electrically op-
erated reversible pre-tensioners in addi-
tion to the pyrotechnic ETDs.


Do not pass belts over sharp edges.
They could tear.


Do not make any modification that could
change the effectiveness of the belts.


Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.


No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).


Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain air bag is deployed.


Air bag system components will be hot
after an air bag has inflated. Do not
touch.

94 Safety and SecurityDriving 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.
Continuous, steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and ability to steer
the vehicle.
The pulsating brake pedal can be an
indication of hazardous road conditions
and functions as a reminder to take extra
care while driving.Emergency brake maneuver

Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (page 248), the ABS designed for
off-road use is automatically activated.
When applying the brakes at speeds below
approximately 18 mph (30 km/h), the
front wheels are locked cyclically to short-
en the braking distance (dig-in effect). This
affects steering the vehicle.For more information, see “Practical hints”
(
page 381).
iWith the ABS malfunctioning, the BAS,
the ESP
®, and the 4-ETS are also
switched off.
The basic 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
afforded. The ABS cannot prevent acci-
dents, including those resulting from exces-
sive speed in turns, following another
vehicle too closely, or hydroplaning. Only a
safe, attentive, and skillful driver can pre-
vent accidents. The capabilities of an ABS
equipped vehicle must never be exploited in
a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.

Switching on the ESP
®

Press ESP
® switch1.
The ESP
® warning lampv in the
instrument cluster goes out.
You are now again in normal driving
mode.
For more information, see “Practical hints”
(
page 381).
Off-road – ESP
®
With the off-road driving program switched
on (
page 248), the ESP
® designed for
off-road use is automatically activated. At
speeds below 27 mph (45 km/h), the
ESP
® assists in over-/understeering, thus
improving vehicle traction.
EBP
The EBP enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort
without a loss of vehicle stability.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 ESP
® warning lampv in the instru-
ment cluster, starts to flash at any vehicle
speed, as soon as a tire loses traction and
the wheel begins to spin.
Warning!
G
When the ESP
® warning lampv is
illuminated continuously, the ESP
® is
switched off.
Adapt your speed and driving to the prevail-
ing road conditions and to the non-operating
status of the ESP
®.
!Avoid spinning of a drive wheel for an
extended period of time with the ESP
®
switched off. This may cause serious
damage to the drivetrain which is not
covered by the Mercedes-Benz Limited
Warranty.
!Turn on the ESP
® immediately if the
aforementioned circumstances do not
apply anymore.
iIf conditions require, switch on

129 Controls in detailSeats
When entering the vehicle, with the
easy-entry/exit feature activated, the
steering wheel or, depending on your se-
lection, the steering wheel and driver’s
seat will return to their last set memory po-
sition or a factory-set maximum forward
position when you:

close the driver’s door with the ignition
switched on


insert the SmartKey into the starter
switch or press the KEYLESS-GO*
start/stop button (

with the driver’s door closed.
iIf the current position for the steering
wheel is in the uppermost tilt position,
the steering wheel will no longer be
able to move upward when the
easy-entry/exit feature is activated.
If the current seat position falls into a
factory-set position range and the sys-
tem recognizes the current seat posi-
tion to be rearward enough for easy
entry and exit, the driver’s seat will not
move to the rear when the
easy-entry/exit feature is activated.
iFor safety reasons, the driver’s seat will
not return to its last set position with
the easy-entry/exit feature activated if
the system recognizes the last set posi-
tion as an extreme forward position. In-
stead, the driver’s seat will remain at or
move to a factory-set maximum for-
ward position. To again fully return the
driver’s seat to your last set position or
to memory position, adjust the seat to
the desired position or press and hold
the respective memory position button
