Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and possible death.
Do not run the engine in confined areas
(such as garage) which are not properly ven-
tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

As independent systems, their protective
effects work in conjunction with each
other. The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The 1indicator lamp in the instrument
cluster comes on when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:


fails to go out after approximately
4 seconds after the engine was started


does not come on at all


comes on after the engine was started
or while driving.

64 Safety and SecurityOccupant safetyWarning!
G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belts.
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 it is properly posi-
tioned on your body.
Since the air bag 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 air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a nearly upright
position with your back against the seat
backrest.


Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 in (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.


Do not lean your head or chest close to
the steering wheel or dashboard.


Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.


Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.


Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door or the rear
side trim panel where the front side im-
pact air bag and/or rear side impact
air bag* inflates. This could result in se-
rious injuries or death should the air bag
be triggered. Always sit nearly upright,
properly use the seat belts and use an
appropriately sized infant or toddler re-
straint or booster seat recommended
for the size and weight of the child.
Failure to follow these instructions can re-
sult in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.

Occupant safety
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both
front side impact air bag and/or rear side
impact air bag* there is a possibility for a
side impact air bag related injury if occu-
pants, especially children, are not properly
seated or restrained when next to a side im-
pact air bag 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 door where the
front side impact air bag and/or rear
side impact air bag* inflates. This could
result in serious injuries or death should
the front side impact air bag and/or rear
side impact air bag* be activated.
(2) Always sit nearly upright, properly use
the seat belts and for children 12 years
old and under, use an appropriately
sized infant or toddler restraint or boost-
er seat recommended for the size and
weight of the child.
(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 impact air bags* deactivated, then
deactivation can be accomplished upon
your written request to do so at your autho-
rized 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.
iAir bags are designed to activate only
in certain frontal impacts (front
air bags), or side impacts (front side
impact air bags, rear side impact
air bags* 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 thresholds, will they provide their
supplemental protection.
The driver and passengers should
always wear their seat belts. Otherwise
it is not possible for air bags to provide
their supplemental protection.
In cases of other frontal impacts, an-
gled impacts, roll-overs, other side im-
pacts, rear collisions, or other
accidents, the air bags will not be acti-
vated. The driver and the passenger will
then be protected by the fastened seat
belts.

66 Safety and SecurityOccupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag We caution you not to rely on the pres-
ence of the air bags in order to avoid
wearing your seat belt.
Your vehicle was originally equipped
with air bags 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-
gers that you replace deployed air bags
and repair any malfunctioning air bags
to make sure the vehicle will continue
to provide supplemental crash protec-
tion for occupants.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 belts in-
stalled or supplied by an authorized
Mercedes-Benz Center.


Air bags and emergency tensioning de-
vices (ETDs) are designed to function on
a one-time-only basis. An air bag or ETD
that was activated must be replaced.


Do not pass belts over sharp edges.
They could tear.


Do not make any modification that could
change the effectiveness of the belts.


Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.


No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the front seat
backrests, door trim panels, or door
frame trims, and installation of addition-
al electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).


Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when curtain air bag is deployed.


Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.


Air bag system components will be hot
after an air bag has inflated. Do not
touch.

68 Safety and SecurityOccupant safetyThe air bags 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 passenger front air bag will only be
deployed if

sor readings, senses that the front pas-
senger seat is occupied

Occupant safety
Seat belts
Always wear your seat belt. All vehicle
occupants always need to have their seat
belts fastened and wear them properly.
In addition, applicable motor vehicle safety
laws require you to wear seat belts. Even
where this is not the case, we strongly
recommend that all vehicle occupants
have their seat belts fastened and wear
them properly.
For more information, see “Fastening the
seat belt” (
page 45).
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and
children, see “Children in the vehicle”
(page 74).
Warning!
G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained, even those sitting in the
rear and pregnant women.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this 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 restraint when the
wearer is in a nearly upright position 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
restrained with a separate seat belt. Never
use a seat belt for more than one person at
a time.
