Occupant safety
Special BabySmartTM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Light Truck
Center are required for use with the
BabySmart
TM air bag deactivation system.
With the special child seat properly
installed, the passenger front air bag will
not deploy.
The 56indicator lamp will be
illuminated, except with the SmartKey
removed or in starter switch position0.Self-test BabySmart
TM without special
child seat installed
After turning the SmartKey in the starter
switch to position1 or2,
the56indicator lamp comes on
for approximately 6 seconds and then
goes out.
If the56indicator lamp should not
come on or is continuously lit, the system
is not functioning. 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 337).
iThe system does not deactivate the
emergency tensioning device.
Warning!G
The BabySmartTM air bag 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.

Child seat anchors – LATCH type
This vehicle is equipped with two LATCH-
(L
ower Anchors and Tethers for CHildren)
type anchors (at each of the outer rear
seats) for installation of a LATCH-type
child seat with matching mounting fittings.
Warning!G
When using a BabySmartTM compatible child
seat on the front passenger seat, the
passenger front air bag will not deploy only
if the56 indicator lamp (
page 81)
remains illuminated.
Make sure to check the 56 indicator
lamp every time you use the special system
child seat. Should the 56 indicator
lamp go out while the restraint is installed,
please check installation. If the 56
indicator lamp 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 may cause
the 56 indicator lamp (
page 81)
not to come on during self-test or be contin-
uously lit, indicating that the system is not
functioning.
Warning!G
Children too big for child restraint systems
must ride in 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 seat belt positioning for children
from 41 lbs until they reach a height where
a lap/shoulder belt fits properly without a
booster.

88 Safety and Security
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 locks 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 vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or pre-
vent the natural laws of physics from acting
on the vehicle.
Always adapt your driving style to the pre-
vailing road and weather 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 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.

89 Safety and Security
Driving 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
respond even to 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 26) 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
pulsation.Emergency brake maneuver
Keep continuous full pressure on the
brake pedal.
Warning!G
When the ABS is malfunctioning, the BAS,
the EBB, 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.

90 Safety and Security
Driving safety systems
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 170).
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 324).
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.
Warning!G
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond 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
system is still functioning normally, but
without the additional brake boost available
that BAS would normally provide in an emer-
gency braking maneuver. Therefore, the
braking distance may increase.

(
page 340).
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 allowed to
flow to the wheel(s) with traction.
The 4-ETS function is available between
vehicle speeds of 0 mph (km/h) and
37 mph (60 km/h).
The ESP
® warning lampv in the instru-
ment cluster (
page 26) comes on when
you switch on ignition (
page 39). It goes
out when the engine is running.
The ESP
® warning lampv starts to
flash at any vehicle speed, as soon as a tire
loses traction and the wheel begins to
spin.
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
When you see the ESP® warning lampv
flashing in the instrument cluster, then
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 4-ETS cannot prevent accidents result-
ing from excessive speed.
