Occupant safety
The air bags will not deploy in impacts
which do not exceed the system’s
deployment thresholds. You will then be
protected by the fastened seat belts.
The passenger front air bag will only be
deployed if:
the front passenger seat is occupied
the56 indicator lamp in the
center console is not lit (
page 75)
the impact exceeds a preset
deployment thresholdFront side impact air bags, rear side im-
pact air bags*, window curtain air bags
The window curtain air bags1 fill up the
area between the A and C pillars (see
arrows).
1Window curtain air bag
2Front side impact air bags
3Rear side impact air bags*The front side impact air bags, rear side
impact air bags* and window curtain
air bags are deployed:
on the impacted side of the vehicle
in impacts exceeding a preset
deployment threshold
independently of the front air bags
The front passenger side impact air bag
will only deploy if the system senses that
the front passenger seat is occupied.
The front side impact air bags, rear side
impact air bags* and window curtain
air bags are not deployed in impacts which
do not exceed the system’s deployment
threshold.
!
Do not place objects heavier than
20 lbs (9 kg) on the front passenger
seat. This could cause the front or side
impact air bag on the front passenger
side to deploy in a crash which exceeds
the system’s deployment threshold.

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
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash, they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!G
USE SEAT BELTS PROPERLY
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 air bag,
passenger front air bag, front side im-
pact air bags, rear side impact
air bags*, head protection window cur-
tain air bags for side windows), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted oc-
cupants in certain frontal (front air bags
and ETD) and side (front side impact
air bags, rear side impact air bags*, win-
dow curtain air bags and ETD) impacts
which exceed preset deployment
thresholds.
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.
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.
