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

Seat belts


Emergency tensioning device


Airbags


Child seat


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each
other.The 1 indicator lamp in the instrument
cluster (
page 26) comes on for about
four seconds when you turn the key in the
steering lock to position2. It goes out
when you start the engine. This shows that
the restraint systems are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately four
seconds or if it comes on thereafter, a mal-
function in the system has been detected.
More information can be found in the
“Practical hints” section (
page 255).
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and chil-
dren, see “Children in the vehicle”
(page 67).
Warning!
G
In the event that the 1malfunction indi-
cator lamp comes on during driving or does
not come at all, the SRS may not be opera-
tional.
For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz
Light Truck Center immediately 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 unexpectedly and unnec-
essarily which could also result in injury.
Improper work on the restraint systems, in-
cluding incorrect installation and removal,
can lead to possible injury through an unin-
tended activation of the SRS.
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
your authorized Mercedes-Benz Light Truck
Center.

60 Safety and SecurityOccupant safety

Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.


Occupants, especially children, should
never lean their heads in the area of the
door where the side impact airbag in-
flates. This could result in serious inju-
ries or death should the airbag be
triggered. Always sit upright, properly
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
TM1
compatible child seat,
which operates with the BabySmart
TM
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 you are responsible
to make the buyer aware of these points. 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 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 70). BabySmart
TM will not, howev-
er, turn off any side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag which needs to deploy rapidly in a
side impact in order to do its job.


61 Safety and Security
Occupant safety
To help avoid the possibility of injury, please
follow these guidelines: (1) occupants, espe-
cially children, should never place their bod-
ies or lean their heads in the area of the door
where the side airbag inflates. This could re-
sult in serious injuries or death should the
side airbag be activated; (2) always sit up-
right, properly use the seat belts and use an
appropriately sized infant or child restraint
system for all children 12 years old or under;
and (3) always wear seat belts properly.
If you believe that, even with the use of
these guidelines, it would be safer for your
rear seat occupants to have both rear door
mounted side airbags deactivated, then de-
activation can be accomplished upon your
written election to do so at your authorized
Mercedes-Benz Light Truck Center at an ad-
ditional cost. Please contact your local au-
thorized Mercedes-Benz Light Truck Center
or call our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.
iAirbags are designed to activate only in
certain frontal (front airbags) impacts,
or side (side impact and head protec-
tion 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.
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 ensure that the vehicle will continue
to provide supplemental crash protec-
tion for occupants.

The side impact airbags and window
curtain airbags are deployed:

on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbagsThe front passenger side impact airbag will
only deploy if the system senses that the
front passenger seat is occupied.
The side impact airbags and window
curtain airbags are not deployed in im-
pacts which do not exceed the system’s
deployment threshold.
Seat belts
When the engine is started, the seat belt
non-usage warning lamp< illuminates
to remind you and your passengers to
fasten your seat belts. If the driver’s seat
belt is not fastened before the engine is
started, the seat belt non-usage warning
lamp< illuminates and a warning
chime sounds for approximately
six seconds when the engine is started.The use of seat belts and infant and child
restraint systems is required by law in all
50 states and all Canadian provinces. Even
where this is not the case, all vehicle occu-
pants should have their seat belts fastened
whenever the vehicle is in motion.
Information on fastening seat belts is
found in the “Getting started” section
(
page 42).iFor information on infants and children
traveling with you in the vehicle and re-
straint systems for infants and chil-
dren, see “Children in the vehicle”
(page 67).

67 Safety and Security
Occupant safety
Emergency tensioning device, seat belt
force limiter
The seat belts for the front seats are
equipped with emergency tensioning de-
vices and belt force limiters. The outboard
passenger seats belts (except in the third
row seats*) are equipped with emergency
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
1indicator lamp (
page 58)
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. Belt force limiters reduce
the force exerted by the seat belts on oc-
cupants 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 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.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. 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 or side
impact airbag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

68 Safety and SecurityOccupant safetyInfant 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 child re-
straint instructions for mounting. Then pull
shoulder belt out completely and let it re-
tract. During the 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. The seat
belt can again be used in the usual man-
ner.

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 system
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 manufacturer of
compliance with this standard can be
found on the instruction label on the re-
straint and in the instruction 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.

69 Safety and Security
Occupant safety
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 ve-
hicle to deactivate the passenger front air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates 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 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.
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 until
they reach a height where a lap / shoulder
belt fits properly without a booster.
When the child restraint is not in use, re-
move 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 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 an accident
and / or serious personal injury.

gency tensioning device.
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 seat, the
passenger front airbag will not deploy only if
the 7indicator lamp remains illumi-
nated.
