54 Safety and SecurityOccupant safety
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 seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems their protective
effects work in conjunction with each oth-
er.The warning lamp
1
in the instrument
cluster (
page 26) lights up for about
4 seconds when the key is turned to
position2. It goes out when you start the
engine. This shows that the restraint sys-
tems are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately
4 seconds or if it comes on thereafter, a
malfunction in the system has been de-
tected.
More information can be found in the
“Practical hints” section (
page 227).
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 63).
Warning!
G
In the event that the SRS malfunction indica-
tor lamp lights up during driving or does not
come at all, the SRS may not be operational.
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 can
lead to unintentional deployment or opera-
tional failure.
All work on these systems should therefore
only be carried out by an authorized
Mercedes-Benz Light Truck Center.

55 Safety and Security
Occupant safety
AirbagsWarning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact and head protec-
tion window curtain airbags) impacts which
may cause significant injuries. However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma 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 airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and passenger to always be in a prop-
erly seated position and to wear your seat
belt.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and ensure that it is properly
positioned on your body (
page 40).
Since the airbag 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 airbag. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured by an airbag as it inflates with great
force in the blink of an eye:


Sit properly belted in an upright position
with your back against the backrest.


Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least ten
inches (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your 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 in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front airbag inflates.


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


56 Safety and SecurityOccupant safety

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
TM compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger side front airbag
when it is properly installed. Otherwise
they will be struck by the airbag when it
inflates in a crash. If this happens, seri-
ous or fatal 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 passenger seat
of your vehicle, you must properly use a
BabySmart
TM child restraint which will turn
off the passenger side front airbag
(
page 65). 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.
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.
