Occupant safety
Warning!
G
Never ride in a moving vehicle with the back-
rest reclined. Sitting in an excessively re-
clined position 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 abdomen or neck. That could cause se-
rious or even fatal injuries. The backrest and
seat belt provide the best restraint when the
wearer is in an 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.
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.
Only use seat belts which have been ap-
proved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
or to failure.
Have all work carried out only by an autho-
rized 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 airbag and
front passenger airbag), ETD (seat belt
emergency tensioning device for driv-
er’s seat, passenger seat and the out-
board passenger seats). The system is
designed to enhance the protection of-
fered to properly belted occupants in
certain frontal (front airbags) impacts
which exceed preset deployment
thresholds.

62 Safety and SecurityOccupant safety
Emergency tensioning device, seat belt
force limiter
The front seat belts and the outboard pas-
senger seats belts are equipped with emer-
gency tensioning devices.
The ETD is designed to activate only when
the seat belt is fastened and in the follow-
ing cases:

in frontal or rear-end impacts exceed-
ing a preset severity level


if the restraint systems are operational
and functioning correctly, see 1
indicator lamp (
page 54)
In an impact, emergency tensioning devic-
es remove slack from the belts in such a
way that the seat belts fit more snugly
against the body.


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


Never wear 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 belt is positioned across your
abdomen, it could cause serious injuries
in a crash.


Each seat belt should never be used for
more than one person at a 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 wouldn’t have the full width
of the belt to manage 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 or on the seat. Always keep both
feet on the floor in front of the seat.

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 and recommended for
use by Mercedes-Benz.


Ensure that the infant or child is prop-
erly secured by a belt at all times while
the vehicle is in motion.
Infant and child restraint seats and infor-
mation on choosing an appropriate re-
straint system can be obtained from any
Mercedes-Benz Light Truck Center.
Infant and child restraint systems
Use only a BabySmart
TM1
compatible child
restraint for the front passenger seat in
this vehicle.We recommend that all infants and
children be properly restrained at all times
while the vehicle is in motion. All lap-shoul-
der belts except the driver’s seat belt have
special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow manufac-
turer’s instructions for mounting child re-
straints. Then pull shoulder belt out
completely and let it retract. During the
seat belt retraction a ratcheting sound can
be heard to indicate that the special seat
belt retractor is activated. 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. The seat
belt can again be used in the usual man-
ner.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be fol-
lowed. These are available at your 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 front airbag
on the front passenger side to deploy in
a crash which exceeds the system's de-
ployment threshold.

Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.!The use of infant or child restraints is
required by law in all 50 states, the
District of Columbia, the U.S. territo-
ries and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured by a
lap-shoulder belt or, if so equipped,
a child restraint lower anchorage sys-
tem 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 man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.
When using any infant or child restraint
system, be 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
Children 12 years old and under must never
ride in the front seat, except in a Mer-
cedes-Benz authorized BabySmart
TM com-
patible child seat, which operates with the
BabySmart
TM System installed in the vehi-
cle to deactivate 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 fatal in-
jury can result.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing 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 manufactur-
er's instructions.

Special BabySmart
TM1
compatible child
seats, designed for use with the Mer-
cedes-Benz system and available at any
authorized Mercedes-Benz Light Truck
Center are required for use with the
BabySmart
TM airbag deactivation system.
With the special child seat properly in-
stalled, the passenger front airbag will not
deploy.
The
7
indicator lamp located in the
center console will be illuminated, except
with the key removed or in the starter
switch position0.
Infants and small children should never
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.
Warning!
G
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
belt positioning for children from 41 lbs. un-
til they reach a height where a lap / shoulder
belt fits properly without a booster.
When the child restraint is not in use, re-
m o v e i t f r o m t h e v e h i c l e o r s e c u r e i t w i t h t h e
seat belt to prevent the child restraint from
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause serious
personal injury.

child seat installed
After turning key in starter switch to
position1 or2, the
7
indicator lamp
located in the center console lights up for
approximately 6 seconds and then goes
out.
If the indicator lamp should not come on or
is continuously lit, the system is not func-
tioning. You must see an authorized Mer-
cedes-Benz Light Truck Center before
seating any child on the front passenger
seat.
More information can be found in the
“Practical hints” section (page 244).
Warning!
G
The BabySmart
TM airbag 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.
When using a BabySmart
TM compatible
child seat on the front passenger side seat,
the front passenger airbag will not deploy
only if the
7
indicator lamp remains il-
luminated.
Warning!
G
Please be sure to check the indicator every
time you use the special system child seat.
Should the light go out while the restraint is
installed, please check installation. If the
light remains out, do not use the
BabySmart
TM restraint to transport children
on the passenger seat until the system has
been repaired.
Warning!
G
Do not place powered-on laptops, cell
phones and like electronic devices on the
front passenger seat. Signals from such de-
vices may interfere with the BabySmart
TM
system. Such signal interference may cause
the
7
indicator lamp not to come on
during self-test or be continuously lit, indi-
cating that the system is not functioning.
