Occupant safety
Air bags
Warning!
G
In the event that the 1indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Light Truck Center immedi-
ately to have the system checked; otherwise
the SRS may not deploy when needed in an
accident, which could result in serious or fa-
tal injury, or it might deploy unexpectedly
and unnecessarily which could also result in
injury.
In addition, improper work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Light
Truck Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Light Truck Center or call
our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.
Warning!
G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags), side impacts (side
impact air bags and head protection window
curtain air bags) or rollovers (head protec-
tion window curtain air bags). However, no
system available today can totally eliminate
injuries and fatalities.
The deployment of the air bags temporarily
releases a small amount of dust from the air
bags. This dust, however, is neither injurious
to your health, nor does it indicate a fire in
the vehicle. The dust might cause some tem-
porary breathing difficulty for people with
asthma 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 air bag inflates, then get
fresh air by opening a window or door.
68 Safety and SecurityOccupant safetyWarning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective 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 make sure that it is prop-
erly positioned on your body (
page 46).
Since the air bag 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 air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag 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 an authorized
Mercedes-Benz Light Truck Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
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’s front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the air bag be triggered. Always sit near-
ly upright, properly use the seat belts
and use an appropriately sized infant or
toddler restraint or booster seat recom-
mended for the size and weight of the
child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.

Occupant safety
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side impact air bag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a side impact air bag which needs to de-
ploy rapidly in a side impact in order to do its
job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the side impact air bag be activated.
(2) Always sit nearly upright, properly use
the seat belts and for children 12 years
old and under, use an appropriately
sized infant or toddler restraint or
booster seat recommended for the size
and weight of the child.
(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 the rear door
mounted side impact air bags deactivated,
then deactivation can be accomplished
upon your written request to do so at an
authorized Mercedes-Benz Light Truck
Center at an additional cost.
Please contact your local authorized
Mercedes-Benz Light Truck Center or call
our Customer Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372)
for details.
iAir bags are designed to deploy only in
certain frontal impacts (front air bags),
and in side impacts (side impact and
head protection window curtain air
bags) which exceed preset thresholds,
and in certain rollovers (head protec-
tion window curtain air bags). Only dur-
ing these events will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for air bags to provide
their supplemental protection.
In case of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not deploy. The
driver and passenger will then be pro-
tected to the extent possible by a prop-
erly fastened seat belt. A properly
fastened seat belt is also needed to
provide the best possible protection in
a rollover.
