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.

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
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 air bags
1 Driver air bag
2 Passenger front air bag
Driver and passenger front air bags are
deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold The air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. You will then be
protected by the fastened seat belts.
The passenger front air bag will only be
deployed if:

the front passenger seat is occupied

the
56 indicator lamp in the
center console is not lit (
page 80)

the impact exceeds a preset deploy-
ment 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 air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from any authorized Mercedes-Benz
Light Truck Center.

Given the considerable deployment
speed and the textile structure of the air
bags, there is the possibility of abra-
sions or other injuries resulting from air
bag deployment.!Do not place objects heavier than 20 lbs
(9 kg) on the front passenger seat. This could
cause the passenger front air bag to deploy in a
crash which exceeds the system’s deployment
threshold.

Window curtain air bags1 Window curtain air bag
The window curtain air bags are deployed:

on the impacted side of the vehicle

in impacts exceeding a preset deploy-
ment threshold

independently of the front air bags
The window curtain air bags are not
deployed in impacts which do not exceed
the system’s deployment threshold.
Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
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 tell-
tale < illuminates and a warning chime
sounds for approximately 6 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. For more information, see “Fastening the
seat belts” (
page 48).
iFor information on infants and children
traveling with you in the vehicle and restraint
systems for infants and children, see “Children
in the vehicle” (
page 77).
Warning!G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear.
Failure to wear and properly fasten and
position 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.
In the same crash, the po ssibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.

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.

Occupant safety
Warning!G
USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this
section, as that could result in serious
injuries in case of an accident.

Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag,
passenger front air bag, window curtain
air bags for side windows), and ETD
(seat belt emergency tensioning
device). The system is designed to en-
hance the protection offered to properly
belted occupants in certain frontal (front
air bags and ETD) and side (window
curtain air bags and ETD) impacts which
exceed preset deployment thresholds.

Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would
increase the chance of head and neck
injuries. The shoulder belt would also
apply too much force to the ribs or abdo-
men, which could severely injure inter-
nal organs such as your liver or spleen.

Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys, etc., as
these might cause injuries.

Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the lap belt is positioned across
your abdomen, it could cause serious
injuries in a crash.

Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.

Seat belts should not be worn twisted.
In a crash, you wouldn’t have the full
width of the seat belt to manage impact
forces. The twisted seat belt against
your body could cause injuries.

Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.

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.

When using a seat belt to secure infant
restraints, toddler restraints or children
in booster seats, a lways follow the child
seat manufacturer’s instructions.

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” (

To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.
The use of infant or child restraints is
required by law in all 50 states, the District
of Columbia, the U.S. territories and all
Canadian provinces.
Infants and small children should be
seated in an appropri
ate infant or child
restraint system properly secured in
accordance with the manufacturer's
instructions for the child restraint, that
complies with U.S. Federal Motor Vehicle
Safety Standards 213 and 225 and
Canadian Motor Vehicle Safety
Standards 213 and 210.2.
A statement by the child restraint
manufacturer of compliance with these
standards can be foun d on the instruction
label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint
system, make sure to carefully read and
follow all manufacturer’s instructions for
installation and use.
Please read and observe warning labels
affixed to inside of vehicle and to infant or
child restraints.
Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

For information on LATCH-type child seat
anchors, see (
page 82).
Warning!G
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 BabySmart
TM system installed in the
vehicle to deactivate 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 can result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle’s
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat
manufacturer’s instructions.
