Occupant safety
The 7indicator lamp located in the
center console will be illuminated, except
with the SmartKey removed or in the start-
er switch position0.
Self-test BabySmart
TM without special
child seat installed
After turning the SmartKey in the starter
switch to position1 or2, the
7indicator lamp located in the center
console comes on for approximately
six seconds and then goes out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized
Mercedes-Benz Light Truck Center before
seating any child on the front passenger
seat.
For more information, see “Practical hints”
section (
page 297).
i
The system does not deactivate the
emergency tensioning device.
Warning!G
The BabySmartTM airbag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.
When using a BabySmart
TM compatible
child seat on the front passenger seat, the
passenger front airbag will not deploy only
if the 7 indicator lamp remains
illuminated.
Warning!G
Make sure to check the indicator every time
you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the front passenger seat until the system
has been repaired.
Warning!G
Do not place powered-on laptops, cell
phones, electronic tags such as those used
in ski passes and like electronic devices on
the front passenger seat. Signals from such
devices may interfere with the BabySmart
TM
system. Such signal interference, for exam-
ple, may cause the 7 indicator lamp not
to come on during self-test or be continu-
ously lit, indicating that the system is not
functioning.

Warning!G
An incorrectly mounted child seat may come
loose during an accident which could result
in serious injury or death to the child.
Damaged or impact-damaged child seats or
child seat mounting fittings must be re-
placed.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system.
Children too big for child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck. A booster
seat may be necessary to achieve proper
belt positioning for children from 41 lbs until
they reach a height where a lap / shoulder
belt fits properly without a booster.

80 Safety and Security
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
t h a t t h e w h e e l s d o n o t l o c k d u r i n g b r a k i n g .
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.
i
In winter operation, the maximum ef-
fectiveness of the ABS, ESP, EBB, and
4-ETS is only achieved with winter tires
or snow chains as required.
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.

81 Safety and Security
Driving and safety systems
Continuous steady brake pedal pressure
yields the advantages provided by the ABS,
namely braking power and the ability to
steer the vehicle.
On slippery road surfaces, the ABS will re-
spond even with light brake pressure. The
pulsating brake pedal can be an indication
of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
The -indicator lamp in the instrument
cluster (
page 24) comes on when you
turn the SmartKey to position2. It goes
out when the engine is running.Braking
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 transfer case in position
LOW (
page 157).
An improved braking action (dig-in effect)
is obtained for vehicle speeds up to
37 mph (60 km/h) through a change in the
ABS control function.
For more information, see “Practical hints”
(
page 290).
i
If the ABS is malfunctioning, the BAS,
EBB, ESP, and 4-ETS are also switched
off.
Normal driving and braking functions
are still available.

82 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.
With the BAS malfunctioning, the ABS,
ESP, and 4-ETS are also switched off.
For more information, see “Practical hints”
(
page 300).
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.
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.

83 Safety and Security
Driving and safety systems
4-ETS
The 4-ETS improves vehicle’s ability to uti-
lize available traction, especially under
slippery road conditions. The brakes are
applied to the spinning wheel and power is
allowed to flow to the wheel(s) with trac-
tion.
The 4-ETS function is available between ve-
hicle speeds of 0 mph (km/h) and 37 mph
(60 km/h).
The ESP warning lampv in the instru-
ment cluster (
page 24) comes on when
you switch on ignition (
page 35). It goes
out when the engine is running.
The ESP warning lampv starts to flash
at any vehicle speed, as soon as the tires
lose traction and the wheels begin to spin.For more information, see “Practical hints”
(
page 295).
Warning!G
When you see the 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 result-
ing from excessive speed.
!
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 4-ETS will engage the
brakes and seriously damage the brake
system.

84 Safety and Security
Driving and safety systems
EBB
The EBB enhances braking effectiveness
by allowing the rear brakes to supply a
greater proportion of the braking effort in
straight line braking circumstances with-
out a loss of vehicle stability.ESP
The Electronic Stability Program (ESP)
monitors the vehicle’s traction (force of ad-
hesive 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 ESP warning lampv in the instru-
ment cluster (
page 24) flashes when the
ESP is engaged.
The ESP warning lampv comes on
when you switch on ignition (
page 35). It
goes out when the engine is running.
Warning!G
Never switch off the ESP when you see the
ESP warning lamp v flashing in the in-
strument cluster. In this case proceed as fol-
lows:

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.
