Safety and Security
Occupant safety
quarter trim panels where the side air-
bag inflates. This could result in serious
injuries or death should the side airbag
be activated.
(2) Always sit upright, properly use the seat belts and use an appropriately sized in-
fant or child restraint system for all chil-
dren 12 years old or under.
(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 side
airbags deactivated, then deactivation can
be accomplished upon your written request
to do so at your authorized Mercedes-Benz
Center at an additional cost.
Please contact your local authorized
Mercedes-Benz 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 impacts (front airbags)
and in side impacts (side impact and
head protection window curtain air-
bags) which exceed preset thresholds.
Only during these types of impacts, if of
sufficient severity to meet the deploy-
ment tresholds, will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for airbags to provide
their supplemental protection.
In cases of other frontal impacts,
angled impacts, roll-overs, other side
impacts, rear collisions, or other acci-
dents, the airbags will not be activated.
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 supplement crash protec-
tion for occupants.

Safety and Security
Occupant safety
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.
Front airbags
Driver and passenger airbags are de-
ployed:

in the event of a frontal impact


if impact exceeds a preset deployment
threshold


independently of the side impact air-
bags
The airbags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts. The front passenger airbag will only be de-
ployed if:


the front passenger seat is occupied


the PASS. AIRBAG OFF indicator lamp
in the center console is not lit
(page 67)


the impact exceeds a preset deploy-
ment threshold.
1 Driver airbag
2 Passenger airbag Side impact airbags, window curtain
airbags
The side impact airbags and window cur-
tain airbags are deployed:


on the impacted side of the vehicle


in impacts exceeding a preset deploy-
ment threshold


independently of the front airbags
The side impact airbags and window cur-
tain airbags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.!Do not place objects heavier than
20 lbs (9kg) 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.

Warning!
G
Never ride in a moving vehicle with the seat
backrest reclined. Sitting in an excessively
reclined 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 serious or even fatal injuries. The seat
backrest and seat belt provide the best re-
straint when the wearer is in an upright po-
sition 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 qualified
technicians. Contact an authorized
Mercedes-Benz 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, pas-
senger front airbag, side impact airbags,
head protection window curtain airbags
for side windows), ETD (seat belt emer-
gency tensioning device), and front seat
knee bolsters. The system is designed
to enhance the protection offered to
properly belted occupants in certain
frontal (front airbags) and side (side im-
pact and window curtain airbags) im-
pacts which exceed preset deployment
thresholds.


64 Safety and SecurityOccupant safety
Emergency tensioning device (ETD)
The seat belts are equipped with emergen-
cy tensioning devices and belt force limit-
ers.
The ETD is designed to activate in the fol-
lowing cases when the seat belts are fas-
tened:

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 56).
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.


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.


Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son 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.
