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, always follow the child
seat manufacturer’s instructions.

Occupant safety
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
1indicator 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.
80 Safety and Security
Occupant safety
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 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
Standards 213 and 210.2.
A statement by the child restraint
manufacturer 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 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.
iFor information on child seats with mounting
fittings for tether anchorages, see “Installation
of infant and child restraint systems”
(
page 84).
For information on LATCH-type child seat
anchors, see (
page 83).
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.

share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
Children too big for child restraint systems
must ride in back 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.When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle; even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.

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

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.
