59 Safety and Security
Occupant safety
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 the rear mount-
ed side airbags deactivated, then deactiva-
tion can be accomplished upon your written
request to do so at your authorized Mer-
cedes-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 (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.

61 Safety and Security
Occupant safety
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

indicator lamp in the center
console is not lit (
page 68).1Driver airbag
2Passenger airbagSide 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 airbags1and2 are not
deployed in impacts which do not exceed
the system’s deployment threshold.
The front passenger side impact airbag1
will only deploy if the system senses that
the front passenger seat is occupied.
!Do not place objects heavier than 20
lbs (9 kg) on the front passenger seat.
This could cause the front or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system's deployment threshold.

64 Safety and SecurityOccupant safetyWarning!
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,
front passenger airbag, side impact air-
bags, head protection window curtain
airbags for side windows), ETD (seat belt
emergency tensioning device), and front
seat knee bolsters. The system is de-
signed to enhance the protection of-
fered to properly belted occupants in
certain frontal (front airbags) and side
(side impact and window curtain air-
bags) impacts which exceed preset de-
ployment thresholds.


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-
m e n . I f t h e b e l t i s p o s i t i o n e d a c r o s s y o u r
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.

65 Safety and Security
Occupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
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
exceeding a preset severity level


if the restraint systems are operational
and functioning correctly. See 1
indicator 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.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When scrapping the emergency tensioning
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Center.
!Do not place objects heavier than 20
lbs (9 kg) on the front passenger seat.
This could cause the front or side im-
pact airbag on the front passenger side
to deploy in a crash which exceeds the
system's deployment threshold.

partment to catch fire. You could be se-
riously burned.


Steam from an overheated engine can
cause serious burns and can occur just
by opening the engine hood. Stay away
from the engine if you see or hear steam
coming from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until it
cools down.
