Occupant safety
Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal
impacts (front air bags), or side impacts
(window curtain air bags). However, no
system available today can completely elim-
inate injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma or other breathing trouble. To avoid
this, you may wish to get out of the vehicle
as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get
fresh air by opening a window or door.
Warning!G
The service life of the passenger front air
bag extends to the date indicated on the
label located on the driver side B pillar. To
provide continued reliab ility after that date,
they should be inspected at an authorized
Mercedes-Benz Light Truck Center at that
time and replaced when necessary.
Warning!G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passen ger to always be in a
properly seated position and to wear their
respective seat belts.
For maximum protection in the event of a
collision always be in no rmal seated position
with your back against the seat backrest.
Fasten your seat belt and make sure it is
properly positioned on your body
(
page 50).
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.

Safety and Security
Occupant safety

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper
operation of vehicle controls. The
distance from the center of the driver’s
breastbone to the center of the air bag
cover on the steering
wheel must be at
least 10 inches (25 cm) or more. You
should be able to accomplish this by a
combination of adjustments to the seat
and steering wheel. If you have any
problems, please see an authorized
Mercedes-Benz Light Truck Center.

Do not lean with your head or chest
close to the steering wheel or dash-
board.

Keep hands on the outside of steering
wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver’s front air bag inflates.

Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

Always sit as upright as possible, prop-
erly use the seat belts and appropriate
size infant or child restraint system.

Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM compatible child seat,
which operates with the BabySmartTM
system installed in the vehicle to deacti-
vate the passenger front air bag when it
is properly installed. Otherwise they will
be struck by the air bag when it inflates
in a crash. If this happens, serious or
fatal injury will result.
Failure to follow thes e instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should yo u choose to place a
child 12 years old or under in the front pas-
senger seat of your vehicle, you must prop-
erly use a BabySmart
TM child restraint which
will turn off the passenger front air bag.
To help avoid the possib ility of injury, please
follow these guidelines:
(1) Always sit as upright as possible, prop- erly use the seat belts and use an appro-
priately sized infant or child restraint
system for all children 12 years old or
under.
(2) Always wear seat belts properly.

Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and air
bagiAir bags are designed to deploy only in
certain frontal impacts (front air bags) and in
side impacts (window curtain air bags) which
exceed preset thresholds. Only during these
events will they provide their supplemental
protection.
The driver and passenger should always wear
their seat belts. Otherwis e it is not possible for
the air bags to provide their supplemental pro-
tection.
In case of other types of impacts and impacts
below air bag deployment thresholds, air bags
will not deploy. The driver and passenger will
then be protected to the extent possible by a
properly fastened seat belt. A properly fastened
seat belt is also needed to provide the best
possible protection in a rollover.
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 pas-
senger that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.
Warning!G

Damaged seat belts or seat belts that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Use only
seat belts installed or supplied at an au-
thorized Mercedes-Benz Light Truck
Center.

Air bags and Emergency Tensioning
Devices (ETDs) are designed to function
on a one-time-only basis. An air bag or
ETD that has deployed must be
replaced.

Do not pass seat belt s over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the seat
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
removing 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 front seat
backrests, door trim panels, or door
frame trims, and installation of
additional electrical/electronic equip-
ment on or near SRS components and
wiring. Keep area between air bags and
occupants free from objects (e.g. pack-
ages, purses, umbrellas, etc.).

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

Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

Safety and Security
Occupant safety
If you are ever in an accident, your injuries
can be considerably
more severe without
your seat belt proper ly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or even fatal injuries. The seat back-
rest and seat belt provide the best restraint
when the wearer is in a nearly upright posi-
tion and the seat belt is properly positioned
on the body.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is
correctly restrained with a separate seat
belt. Never use a seat belt for more than one
person at a time.
Warning!G
Damaged seat belts or seat belts that were
highly stressed in an accident must be re-
placed and their anchoring points must also
be checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifi cations to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate
when necessary.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency
tensioning devices and seat belt force
limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding the system deployment
threshold

if the restraint systems are operational
and functioning correctly, see
1
indicator lamp (
page 68) When activated, emergency tensioning
devices remove slack from the seat belts in
such a way that the seat belts fit more
snugly against the body. Seat belt force
limiters reduce the force exerted by the
seat belts on occupants during a crash.
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is
properly secured at all times while the
vehicle is in motion.
iThe ETDs for the front seats will only acti-
vate if the respective front seat belt is fastened
(latch plate properly inserted into buckle).
The ETDs for the rear outer seats will activate
with or without the respective seat belt fastened.
Warning!G
An Emergency Tensioning Device (ETD) that
was activated must be replaced.
When disposing of emergency tensioning
device, our safety instructions must be
followed. These are available at any autho-
rized Mercedes-Benz Light Truck Center.
!Do not place objects heavier than 20 lbs
(9 kg) on the front passenger seat. This could
cause the passenger front air bag and, with the
seat belt fastened to secure the object, the ETD
on the front passenger side to deploy in a crash
which exceeds the system’s deployment thresh-
old.

Infant and child restraint systems
Only use a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt and the rear center seat belt have
special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat b elt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.Warning!G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could

injure themselves on parts of the vehicle

be seriously or fatally injured through
excessive exposure to extreme heat or
cold
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for exampl e, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could

injure other persons

get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger or cargo compartment unless
they are firmly secured in place. For more
information, see “Loading” (
page 206)
and “Useful features” (
page 215).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of

strong braking maneuvers

sudden changes of direction

Special BabySmartTM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Merced es-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 56 indicator lamp will be
illuminated, except with the SmartKey
removed or in starter switch position 0. Self-test BabySmart
TM without special
child seat installed
After turning the SmartKey in the starter
switch to position 1 or 2,
the 56 indicator lamp comes on
for approximately 6 seconds and then
goes out.
If the 56 indicator 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 335).
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 wit h 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 th e 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 th e child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.

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 position 2. 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 malf
unctioning, 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.
