approximately 4 seconds or if it comes on thereafter, a
malfunction in the system has been detected.
The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.
Initially, when the electronic key is turned from starter
switch position 0 to position 1 or 2, malfunctions in the
crash sensor are detected and indicated (the “SRS”
indicator lamp stays on longer than 4 seconds or does
not come on).
Have the system checked at your authorized
Mercedes-Benz Center immediately.In the operational mode, after the indicator lamp has
gone out following the initial check, interruptions or
short circuits in the airbag ignition circuit and in the
driver and front passenger seat belt buckle harnesses,
and low voltage in the entire system are detected and
indicated.
Note:
See page 293 for information on the supplemental
restraint system (SRS) indicator lamp.
Wa r n i n g !
In the event a malfunction of the “SRS” is indicated
as outlined above, the “SRS” may not be
operational. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have the
system checked; otherwise the “SRS” may not be
activated when needed in an accident, which could
result in serious or fatal injury, or it might deploy
unexpectedly and unnecessarily which could also
result in injury.

The driver and passenger front airbags are designed to
activate only in certain frontal impacts exceeding a
preset threshold. The front passenger airbag deploys
only if the front passenger seat is occupied and the
7indicator lamp on the center console is not
illuminated.Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.

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.
The side impact airbag for the right rear passenger
deploys only if a preset threshold is exceeded. The side
impact airbag for the left rear passenger deploys
together with the side impact airbag for the driver.
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 airbags
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.
The window curtain airbags are designed to activate
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.
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.

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 !
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 w ith 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:
• Sit properly belted in an upright position with
your back against the backrest.• Adjust the driver seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the
steering wheel or dashboard.• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand/arm injury when driver front airbag
inflates.• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.

• Occupants, especially children, should never
lean their heads in the area of the door or rear
quarter interior trim panel where the side
airbag inflates. This could result in serious
injuries or death should the airbag be
triggered. Always sit upright, properly use the
seat belts and appropriate size infant or child
restraint system.• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with the
BabySmart
TM system installed in the vehicle to
deactivate the passenger side front airbag
when it is properly installed. Otherwise they
will be struck by the airbag when it inflates in
a crash. If this happens, serious or fatal injury
can result.
Failure to follow these instructions can result in
severe injuries to you or other occupants.
Wa r n i n g !
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmart
TM
child
restraint which will turn off the passenger side
airbag. BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both front
and rear side impact airbags there is a possibility
for a side airbag related injury if occupants,
especially children, are not properly seated or
restrained when next to a side airbag 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) occupants, especially
children, should never place their bodies or lean
their heads in the area of the front door or rear
quarter trim panels where the side airbag 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 infant or child restraint system
for all children 12 years old or under; and (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 quarter trim panel
mounted side airbags deactivated, then
deactivation can be accomplished upon your
written election to do so at your authorized
Mercedes-Benz Center at an additional cost. Please
contact your local authorized Mercedes-Benz
Center or call our Client Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372) for details.

Safety guidelines for the seat belt, emergency
tensioning retractor and airbag
Wa r n i n g !
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.• Airbags and “ETR’s” are designed to function
on a one-time-only basis. An airbag or
emergency tensioning retractor (ETR) that was
activated must be replaced.• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, door trim panels, or door frame trims,
and installation of additional electrical/
electronic equipment on or near “SRS”
components and wiring. Keep area between
airbags and occupants free from objects (e.g.
packages, purses, umbrellas, etc.).
• Do not pass belts over sharp edges.• Do not make any modification that could
change the effectiveness of the belts.• Do not use handles or coat hooks above doors
and rear windows for placing such items as
coat hangers etc..• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.• In addition, through improper work there is a
risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Center.
