WARNING
Air bagsa re designed to reduce the incidence
of injurie sand fatalities in certain situations:
R frontal impacts (driver's and front-
passenger front air bagsa nd knee bags)
R side impacts (sid eimpact air bags, window
curtai nair bags and pelvis air bags)
R rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, asmall
amount of powder is released .The powder
generally does not constitute ahealth hazard
and does not indicate that there is afire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave 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 air bag inflates,
then get fresh air by opening awindow or
door. G
WARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body. As the air bag inflates with considerable
speed and force,
aproper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at asafe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag, as it
inflates with great force instantaneously:
R sit with the seat belt fastened correctly and
in ap osition that is as upright as possible
with your back against the backrest.
R move the driver's seat as far back as
possible, still permittingp roper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Ben zCenter.
R do not lean your head or chest close to the
steerin gwheel or dashboard.
R only hold the steerin gwheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severit yof
hand/arm injury if the driver fron tair bag
inflates.
R adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R occupants, especially children ,should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates .This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint,t oddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants. Occupant safety

If the air bags are deployed, you will hear a
bang, and asmall amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicat ethat there
is af ire in the vehicle. The dust might cause
some temporary breathin gdifficulty 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.
You can also open the window to allow fresh
air to enter the vehicle interior. The 0012SRS
warning lamp lights up.
The air bag installation location sare
identified by the AIR BAG symbol.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in
the event of such asituation will the air bags
provide their supplemental protection.
If the driver and fron tpassenger do no twear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passenger will then be protected
to the extent possible by aproperly fastened
seat belt. Aproperl yfastened seat beltisa lso
needed to provide the best possible
protection in arollover.
Air bags provide additional protection; they
are not, however, asubstitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective function for the vehicle occupants in the
event of
acrash.
i After an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.

If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in achild restraint system
R is occupied by asmall individual, such as a
young teenager or asmall adult
R is occupied by achild in achild restraint
system whose weight is greater than that

Important safety notes G
WARNING
The seat belt does not offer the intended level
of protection if the backrest is not in the
upright position. When braking or in the event of an accident
,you could slide underneath the
seat belt and sustain abdomen or neck
injuries, for example. This poses an increased
risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always make sure that the seat
is in the upright position. G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, extremely dirty,
bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R the Emergency Tensionin gDevices or the
belt anchorage has been modified.
Damage caused to seat belts in an accident
may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified Emergency Tensionin gDevices may
be deployed unintentionally or fail to be
deployed when required. There is an
increased risk of injury, possibly even fatal.

WARNING
US ES EATB ELTS PROPERLY
R Seat belt scan only work when used
properly. Never wear seat belt sinany other
way than as describe dinthiss ection, as
that coul dresult in serious injuries in the
event of an accident.
R Eac hoccupan tshould wear their seat belt
at all 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 front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
EmergencyT ensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
R Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In af rontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck.N ever pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet. R
Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your
abdomen, it could cause serious injuries in
ac rash.
R Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
R Make sure the seat belt is alway sfitted
snugly. Take special care of this when
wearing loose clothing.
R Never use aseat belt for more than one
person at atime. Do not fasten aseat belt
around aperson and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribut eimpact forces.
The twisted seat belt against yourb ody
could cause injuries.
R Pregnant women should also alwaysu se a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R Place the seat backrest in aposition that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned.
R 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.
R When using aseat belt to secure infant
restraints, toddler restraints, or children in
booster seats, alwaysf ollow the child seat
manufacturer' sinstructions.

Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommendt hat
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint,t oddler restraint,orb ooster
seat recommended for the size and weight of
the child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and top tether strap, or lower anchors and
top tether strap, fully in accordance with the
child seat manufacturer's instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint,t oddler restraint,orb ooster seat recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place
achild in the front
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of astandard appropriate
child restraint on the front passenger seat.
R For children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be activated.
Always make sure the 000F000Bindicator
lamp is illuminated, indicatin gthat the front
passenger front air bag is deactivated.
R Ac hild in arear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates in acollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to
completely eliminate this risk is to never
place achild in arear-facing child restraint
in the front seat. We therefore strongly
recommendt hat you always place achild
in ar ear-facing child restraint in abackseat.
R If you must install arear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 000F000Bindicator
lamp is illuminated, indicatin gthat the front
passenger front air bag is deactivated.

If you fail to adapt your driving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are responsible for the distance to the vehicle in
front,f
or vehicle speed and for braking in
good time. Always adapt your driving style to
suit the prevailing road, weather and traffic
conditionsa nd maintain asafe distanc efrom
th ev ehicle in front. Drive carefully.
