deal of useful information. We urge you to
read it carefully and familiarize yourself
with the vehicle before driving.
For your own safety and longer service life
of the vehicle, we urge you to follow the in-
structions and warnings contained in this
manual. Ignoring them could result in dam-

Your vehicle may have some or all of the
equipment described in this manual.
Therefore, you may find explanations for
optional equipment not installed in your
vehicle. If you have any questions about
the operation of any equipment, your
authorized Mercedes-Benz Light Truck
Center will be glad to demonstrate the
proper procedures.We continuously strive to improve our
product, and ask for your understanding
that we reserve the right to make changes
in design and equipment. Therefore, infor-
mation, illustrations and descriptions in
this Operator’s Manual might differ from

71 Safety and Security
Occupant safety
Air bags
Air bags or emergency tensioning devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the de-
celeration threshold for air bag deployment
is exceeded. Therefore, never modify the re-
straint systems. Do not tamper with elec-
tronic components or their software.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.
Contact an authorized Mercedes-Benz Light
Truck Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact a 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 win-
dow curtain air bags) or rollovers (head pro-
tection window curtain air bags). However,
no system available today can totally elimi-
nate 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.

Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag
It should be noted that with respect to both,
front side impact air bags or the rear side
impact air bags*, there is a possibility for a
side impact air bag related injury if occu-
pants, especially children, are not properly
seated or restrained when next to a side
impact air bag 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) 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.
(2) Always wear seat belts properly.
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.
i
Air 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 during these
events will they provide their supplemental pro-
tection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not deploy. The driver and passenger will then be
protected to the extent possible by a properly
fastened seat belt. A properly fastened seat belt
is also needed to provide the best possible pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.
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 belts in-
stalled or supplied by an authorized
Mercedes-Benz Light Truck Center.
Air bags and pyrotechnic emergency
tensioning devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced.
Do not pass belts over sharp edges.
They could tear.
Do not make any modification that could
change the effectiveness of the belts.
