Driving safety systems
Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Off-road – ABS
With the off-road driving program switched
on (
page 268), 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 413).
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 continuous 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.
Warning!
G
When the ABS is malfunctioning, the BAS,
the ESP
®, and the 4-ETS are also switched
off. The basic driving and braking functions
are still available.
When the ABS is malfunctioning, the wheels
may lock during hard braking, reducing
steering capability and extending the brak-
ing distance.
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
excessive 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.
Warning!
G
If the BAS is malfunctioning, the brake sys-
tem is still functioning, but without the addi-
tional brake boost available that BAS would
normally provide in an emergency braking
maneuver. Therefore, the braking distance
may increase.

98 Safety and SecurityDriving safety systems
ESP
®
The Electronic Stability Program (ESP
®) is
operational as soon as the engine is run-
ning. It 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 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 helps stabilize the vehicle during
braking maneuvers.
The ESP
® warning lampv in the instru-
ment cluster (
page 26) flashes when the
ESP
® is engaged.
The ESP
® warning lampv in the instru-
ment cluster come on when you switch on
the ignition. It goes out when the engine is
running.
Warning!
G
The BAS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking efficiency beyond that
afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The BAS cannot prevent accidents, includ-
ing those resulting from excessive speed in
turns, following another vehicle too closely,
or hydroplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must
never be exploited in a reckless or danger-
ous manner which could jeopardize the
user’s safety or the safety of others.
Warning!
G
Never switch off the ESP
® when you see the
ESP
® warning lampv flashing in the in-
strument cluster. 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 result-
ing from excessive speed.

Driving safety systems
For more information, see the “Practical
hints” section (
page 419) and
(
page 436).Switching off the ESP
®
To improve the vehicle’s traction, switch
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:


when driving with snow chains


in deep snow


in sand or gravel
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 hydro-
planing. Only a safe, attentive, and skillful
driver can prevent accidents. The capabili-
t i e s o f a n E S P
® equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user’s
safety or the safety of others.
!
Operational or performance test must only
be conducted on a two-axle dynanometer. 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 position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the brakes on a
brake test dynamometer and such testing should
be no longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
i
The ESP
® will only function properly if you
use wheels of the recommended tire size
(
page 536).
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.
Do not switch off the ESP
® when a spare
wheel is mounted.

101 Safety and Security
Driving safety systems
For more information, see “Practical hints”
(page 413).
Off-road – ESP
®
With the off-road driving program switched
on (
page 268), 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.
ESP® Trailer Stabilization
If the trailer you are towing should begin to
sway, the rig can only be stabilized by
immediately applying the brakes hard.
Steering during this maneuver will not help
to stabilize the rig.
ESP® will assist you in such situations.
ESP® recognizes when the trailer starts
swaying and will apply the brakes to re-
duce the vehicle speed to a non-critical
speed that allows the vehicle-trailer combi-
nation to stabilize.The ESP
® Trailer Stabilization is functional
at vehicle speeds above approximately
40 mph (65 km/h) when the ESP
® is
switched on.
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.
For more information, see the “Practical
hints” section (
page 416) and
(
page 448).
Warning
G
The system will not be able to assist when
the trailer jackknifes

on wet or icy roads


on roads with slippery surface


in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying
of the trailer.
i
If the ESP
® has switched off due to a mal-
function, ESP® cannot stabilize the rig.
Warning!
G
If the EBP is malfunctioning, the brake sys-
tem is still functioning. 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 EBP.

102 Safety and SecurityDriving safety systems4-ETS
The 4-Electronic Traction System (4-ETS)
improves the vehicle’s ability to utilize
available traction, especially under
slippery road conditions. The brakes are
applied to the spinning wheel and power is
transferred 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.
For more information, see the “Practical
hints” section (
page 414) and
(
page 428).
Off-road - 4-ETS
With the off-road driving program switched
on (page 268), the 4-ETS designed for
off-road use is automatically activated.
i
If conditions require, switch on off-road
driving program (
page 268).
Warning!
G
When you see ESP
® warning lampv
flashing in the instrument cluster, then pro-
ceed 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 4-ETS cannot prevent accidents resul-
ting from excessive speed.
!
Operational or performance test must only
be conducted on a two-axle dynanometer. 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 position0 or1 or
KEYLESS-GO* start/stop button in
position0or1) when testing the brakes on a
brake test dynamometer and such testing should
be no longer than 10 seconds.
Active braking action through the ESP
® may
otherwise seriously damage the brake system
which is not covered by the Mercedes-Benz
Limited Warranty.
i
If the yellow ESP
® warning lampv
comes on while driving, the 4-ETS is being
switched off temporarily to prevent overheating
of the drive wheel brakes. In addition, the
message
ESP inoperative See Operator’s
Manual appears in the multifunction display.

190 Controls in detailAutomatic transmission!
If you want the gear position to remain in
neutral positionN (for example when the vehicle
is pulled through a car wash)


do not remove the SmartKey from the starter
switch
or, when using KEYLESS-GO*


do not turn off the engine using the
KEYLESS-GO start/stop button* and open
the driver’s door
Otherwise, the transmission will shift to park
positionP and lock the wheels, preventing the
vehicle from being pulled through a car wash.
Effect
í
Reverse gear
Shift into reverse gearR only
when the vehicle is stopped.
Effect
ë
Neutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).To avoid damage to the trans-
mission, avoid shifting into
neutral positionN while driving,
except:
If the ESP
® is deactivated or
malfunctioning:
Shift into neutral positionN only
when the vehicle is in danger of
skidding, e.g. on icy roads.
ê
Drive
The transmission shifts
automatically. All forward gears
are available.
!
Coasting the vehicle, or driving for any other
reason in neutral positionN can result in trans-
mission damage that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle without shifting
into park positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 65).
When parked on an incline, turn the front
wheels towards the road curb.
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.
