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 section, as that could result
in serious injuries in case of an accident.• E ach oc c upan t s houl d wear t hei r s ea t bel t a t al l
times, because seat belts help reduce the
likelihood of and potential severity of injuries
in accidents, including rollovers. The
integrated restraint system includes “SRS”
(driver airbag, front passenger airbag, side
impact airbags, head protection window
curtain airbags for side windows), “ETR” (seat
belt emergency tensioning retractors), 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 impact and
window curtain airbags) impacts which exceed
preset deployment thresholds.
• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. 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 severely 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 abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person 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.

Side impact airbags, window curtain airbags
3Side impact airbags
4Window curtain airbagsSide impact airbags
The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbags on the impacted side of the
vehicle deploy.
The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.
Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.
Note:
Heavy objects on front passenger seat can cause the
front passenger side impact airbag to deploy in a crash.
Window curtain airbag
The head protection window curtain airbags afford
greater protection against injuries to the head and
upper body. They fill up in the area between the A and
C pillars (see arrows) between the side windows and an
occupant’s head.

only in certain side impacts exceeding a preset
threshold. Only the head protection window curtain
airbag on the impacted side of the vehicle deploys.Important!
Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
and head protection window curtain airbags)
impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.
The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their supplemental protection.
In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents, 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 presence of the
airbags in order to avoid wearing your seat belt.

Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passenger that you replace deployed
airbags and repair any malfunctioning airbags to
ensure the vehicle will continue to provide crash
protection for occupants.
Wa r n i n g !
Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts, or
side (side impact and head protection window
curtain airbags) impacts which may cause
significant injuries, however, no system available
today can totally eliminate injuries and fatalities.The activation of the “SRS” temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious to your health, nor
does it indicate a fire in the vehicle. The dust might
cause some temporary 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
airbag inflates, then get fresh air by opening a
window or door.The service life of the airbags extends to the date
indicated on the label located on the driver side
door latch post. To provide continued reliability
after that date, they should be inspected by an
authorized Mercedes-Benz Center at that time and
replaced when necessary.

To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear your 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
ensure that it is properly positioned on your body.Since the airbag 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 airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:
