Occupant safety
Seat belts
Always wear your seat belt. All vehicle
occupants 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
recommend that all vehicle occupants
have their seat belts fastened and wear
them properly.
For more information, see “Fastening the
seat belts” (
page 51).

For information on infants and children
traveling with you in the vehicle and restraint
systems for infants and children, see “Children
in the vehicle” (
page 82).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure all of 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. Air bags 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 seat 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. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.

78 Safety and SecurityOccupant safetyWarning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
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.
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 sec-
tion, as that could result in serious inju-
ries 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, pas-
senger front air bag, side impact air
bags, head protection window curtain
air bags for side windows), ETD (seat
belt emergency tensioning device), and
front seat knee bolsters. The system is
designed to enhance the protection of-
fered to properly belted occupants in
certain frontal (front air bags and ETD)
and side (side impact, window curtain
air bags and ETD) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air
bags and ETD).


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 in-
crease the chance of head and neck in-
juries. The belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.


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


Position the lap belt as low as possible
on your hips and not across the abdo-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
abdomen, it could cause serious injuries
in a crash.

Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your pas-
sengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a maxi-
mum of 6 seconds or until the driver’s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with front doors closed,

the seat belt telltale< remains illu-
minated for as long as either the driv-
er’s or front passenger’s seat belt is not
fastened


and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing intensity for a maximum of 60 seconds
or until the driver’s and the front pas-
senger’s seat belt are fastened.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a front door is opened.
For more information, see “Practical hints”
(
page 421).


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


Belts should not be worn twisted. In a
crash, you would not have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.


Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure 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
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

80 Safety and SecurityOccupant safetyEmergency Tensioning Device (ETD),
seat belt force limiter
Depending on vehicle production date, the
seat belts for the front and rear or rear
outer seats are equipped with emergency
tensioning devices and belt force limiters.
The ETD is designed to activate in the
following cases:

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


in certain vehicle rollovers


if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 423)In an impact, emergency tensioning
devices remove slack from the belts in
such a way that the seat belts fit more
snugly against the body. Belt force limiters,
when activated, are employed to help
reduce the peak force exerted by the seat
belts on occupants during a crash.
Active head restraint
The active head restraints are intended to
offer the driver and front passenger
increased protection from whiplash type
injuries. In the event of a rear-end collision,
the active head restraints on the driver’s
and front passenger’s seats are designed
to move forward in the direction of travel,
providing the head with increased support
earlier on in the collision sequence. The
active head restraints move forward
whether the seat is occupied or not.
i
The 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 or rear outer seats (de-
pending on vehicle production date) will activate
with or without the respective seat belt fastened.
Warning!
G
A pyrotechnic emergency tensioning device
(ETD) that was activated must be replaced.
When disposing of the pyrotechnic emer-
gency tensioning device, our safety instruc-
tions must be followed. These are available
at your authorized Mercedes-Benz Light
Truck Center.
Warning!
G
Only use seat or head restraint covers which
have been tested and approved by
Mercedes-Benz for your vehicle model.
Using other seat or head restraint covers
may interfere with or prevent the activation
of the active head restraint. Contact an
authorized Mercedes-Benz Light Truck
Center for availability.

81 Safety and Security
Occupant safety
You cannot remove the active head
restraint on the driver’s and front
passenger’s seats.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Light Truck
Center.
For information on head restraint adjust-
ment, see “Seats” (
page 43).
For information on resetting the activated
active head restraints, see “Resetting acti-
vated head restraints” (page 479).
Rear head restraints
Do not attach any objects (e.g. hangers) to
the head restraints posts. Otherwise, the
active head restraints may not be able to
function properly or offer the intended
degree of protection in the event of an
accident.Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that it is as close to
the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Warning!
G
Do not drive the vehicle without the seat
head restraints installed when the rear seats
are occupied. Head restraints are intended
to help reduce injuries during an accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint properly.
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that
it is as close to the head as possible and the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.

82 Safety and SecurityOccupant safetyChildren 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.Infant and child restraint systems
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 have special seat belt retractors
for secure fastening 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 belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. To deacti-
vate the special seat belt retractor for the
front passenger seat, the front passenger
seat must be in the most backward posi-
tion. The seat belt can again be used in the
usual manner.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 example, could become very
hot, and the child could be turned 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 in-
formation, see “Loading” (
page 281) and
“Useful features” (
page 294).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of


strong braking maneuvers


sudden changes of direction


an accident

83 Safety and Security
Occupant safety
The use of infant or child restraints is re-
quired by law in all 50 states, the District
of Columbia, the U.S. territories and all Ca-
nadian provinces.Infants and small children should be seat-
ed in an appropriate 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 Standard
213 and 210.2.
A statement by the child restraint manu-
facturer of compliance with these
standards can be found 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 the inside of the 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.i
For information on child seats with mounting
fittings for tether anchorages, see “Installation
of infant and child restraint system”
(
page 92).
For information on LATCH-type child seat
mounts, see “Child seat anchors – LATCH type”
(page 91).
Warning!
G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s
instructions.


84 Safety and SecurityOccupant safetyAlways sit nearly upright, properly use the
seat belts and use an appropriately sized in-
fant or toddler restraint or booster seat rec-
ommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances
require you to place a child in the front
passenger seat:

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the OCS senses the weight of a
typical 12-month-old child or less along
with the weight of a standard
appropriate child restraint on the front
passenger seat.


A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front
passenger front air bag inflates in a
collision which could occur under some
circumstances, even with the air bag
technology installed in your vehicle. The
only means to completely eliminate this
risk is to never place a child in a rear-fac-
ing child restraint in the front seat. We
therefore strongly recommend that you
always place a child in a rear-facing
child restraint in the back seat.


If you must install a rear-facing child
restraint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the
59indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the 59indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the
59indicator lamp while
driving to make sure the lamp is illumi-
nated. If the 59indicator
lamp goes out or remains out, do not
transport a child on the front passenger
seat until the system has been repaired.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates.
