In this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
Occupant safety
The restraint systems are

Seat belts

Emergency tensioning device

Airbags

Child seats

Child seat recognition

Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each oth-
er.The 1indicator lamp in the instrument
cluster (
page 25) comes on:

for about four seconds when you turn
the SmartKey in the starter switch to
position1.

for about four seconds when you start
the engine by turning the SmartKey.
The 1indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.

Occupant safety
A malfunction in the system has been de-
tected if the 1 indicator lamp:

fails to extinguish after approximately
four seconds.

does not come on at all.

comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Light Truck Center imme-
diately to have the system checked.
For more information, see “Practical hints”
(
page 296).
Airbags
Warning!G
In the event that the 1indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately to have the system checked; otherwise
the SRS may not be activated when needed
in an accident, which could result in serious
or fatal injury, or it might deploy unexpect-
edly and unnecessarily which could also re-
sult in injury.
In addition, through improper work there is
a risk of rendering the SRS inoperative or
causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact an
authorized Mercedes-Benz Light Truck
Center.Warning!G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, which may cause significant injuries.
However, no system available today can to-
tally eliminate injuries and fatalities.
The activation of the airbags temporarily re-
leases 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 airbag inflates, then get
fresh air by opening a window or door.

64 Safety and Security
Occupant safety
Warning!G
The service life of the passenger front airbag
extends to the date indicated on the label lo-
cated on the driver side B pillar. To provide
continued reliability after that date, they
should be inspected by 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
airbags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear your
seat belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure it is properly
positioned on your body (
page 68).
Since the airbag 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 airbag.
Occupants who are unbelted, out of position
or too close to the airbag can be seriously
injured or killed by an airbag as it inflates
with great force in the blink of an eye:

Sit properly belted in a nearly upright
position with your back against the
backrest.

Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least
ten inches (25 cm) or more. You should
be able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, 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 in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.

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

65 Safety and Security
Occupant safety

Always sit nearly upright, properly use
the seat belts and appropriate size in-
fant or child restraint system.

Children 12 years old and under must
never ride in the front seat, except in a
Mercedes-Benz authorized
BabySmart
TM1 compatible child seat,
which operates with the BabySmartTM
system installed in the vehicle to deacti-
vate the passenger front airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult in severe injuries to you or other occu-
pants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.

Automotive Corp.
Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag
(
page 74).
i
Airbags are designed to activate only in
certain frontal (front airbags) impacts
and in side (head protection window
curtain airbags) impacts which exceed
preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment thresholds, will they provide their
supplemental protection.
The driver and passenger should al-
ways wear their seat belts. Otherwise it
is not possible for the airbags to pro-
vide their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents, the airbags will not be acti-
vated. The driver and passengers will
then be protected by the fastened seat
belts.
We caution you not to rely on the pres-
ence of the airbags in order to avoid
wearing your seat belt.

Safety guidelines for the seat belt,
emergency tensioning device and
airbag Your vehicle was originally equipped
with airbags that are designed to acti-
vate in certain impacts exceeding a
preset threshold to reduce the poten-
tial and severity of injury. It is important
to your safety and that of your passen-
ger that you replace deployed airbags
and repair any malfunctioning airbags
to make sure the vehicle will continue
to provide supplemental crash protec-
tion 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. Use only belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.

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, passenger front airbag cov-
er, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical /electronic equipment on or
near SRS components and wiring. Keep
area between airbags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Airbags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time-only basis. An airbag or ETD
that was activated must be replaced.

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.

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.

Airbag system components will be hot
after an airbag has inflated. Do not
touch.

When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.Front airbags
1Driver airbag
2Passenger front airbag
Driver and front passenger airbags are
deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air-
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

For your protection and the protection
of others, when scrapping the airbag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from an authorized Mercedes-Benz
Light Truck Center.

Given the considerable deployment
speed and the textile structure of the
airbags, there is the possibility of abra-
sions or other injuries resulting from
airbag deployment.
Warning!G
In the event that the 1indicator lamp
comes on while driving, the SRS may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately to have the system checked; otherwise
the SRS may not be activated when needed
in an accident, which could result in serious
or fatal injury, or it might deploy unexpect-
edly and unnecessarily which could also re-
sult in injury.

Occupant safety
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The passenger front airbag will only be
deployed if:

the passenger seat is occupied

the 7 indicator lamp in the center
console is not lit (
page 74)

the impact exceeds a preset deploy-
ment thresholdWindow curtain airbags
The window curtain airbags1 deploy in
the area of the side windows indicated by
the arrows.
1Window curtain airbag
The window curtain airbags are deployed:

on the impacted side of the vehicle

in impacts exceeding a preset deploy-
ment threshold

independently of the front airbags
The window curtain airbags are not de-
ployed in impacts which do not exceed the
system’s deployment threshold.
Seat belts
When the engine is started, the seat-belt
telltale< illuminates to remind you and
your passengers to fasten your seat belts.
If the driver’s seat belt is not fastened be-
fore the engine is started, the seat belt
telltale< illuminates and a warning
chime sounds for approximately
six seconds when the engine is started.
Always wear your seat belt. All vehicle oc-
cupants always need to have their seat
belts fastened and wear them properly.
In addition, applicable motor vehicle safety
laws require you to wear seat belts. Even
where this is not the case, we strongly rec-
ommend that all vehicle occupants have
their seat belts fastened and wear them
properly.
For more information, see “Fastening the
seat belt” (
page 43).
!
Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the passenger
front airbag to deploy in a crash which
exceeds the system’s deployment
threshold.

Warning!G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly 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.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Airbags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.
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 belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The backrest and seat
belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Be sure
everyone riding in the vehicle is correctly re-
strained with a separate seat belt. Never use
a seat belt for more than one person at a
time.
