head restraints, for example
R use head restraint covers
If you do so, the head restraint scannot fulfill
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraint scould endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head

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.
Never modify seat belts, Emergency
Tensionin gDevices, seat belt anchorages and
inertia reels. Ensure that seat belts are not
damaged or worn and are clean.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
The use of seat belts and infant and child
restraint systems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadia nprovinces
Even where this is not required by law,a ll
vehicl eoccupants should correctly fasten
their seat belts before starting the journey.

WARNING
Pyrotechnic Emergency Tensioning Devices
that have been deployed are no longer
operational and are unable to perfor mtheir
intended protective function. This poses an
increased risk of injury or even fatal injury.
Therefore, have pyrotechnic Emergency
Tensioning Devices which have been
triggered immediately replaced at aqualified
specialist workshop.
! If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger seat. Otherwise, the Emergency Tensioning Device could be triggered in the
event of an accident.

Tensioning Devices that are triggered by an
electric motor can be deployed as often as
desired and do not need to be replaced.
The front seat belts and the outer seat belts
in the rear are equipped with Emergency
Tensioning Devices and seat belt force
limiters.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrects eat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
The ETDs can only be activated when:
R the ignition is switched on
R the restraint systems are operational; see
"SRS warning lamp 0012"(Ypage 41)
R the belt tongue is engaged in the buckle on
each of the front seat belts.
The ETDs on the outside seats in the rear

the lock status of the seat belts.
The ETDs are triggere ddepending on the type
and severity of an accident:

health hazard and does not indicate that there

af ire 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.
You can also open the window to allow fresh
air to enter the vehicle interior. The 0012SRS
warning lamp lights up.
If the seat belt is also equipped with aseat
belt force limiter and this is triggered, the
force exerted by the seat belt on the vehicle
occupant is reduced.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which take on apart of the deceleration force.
This results in the force exerted on the
occupant being distributed over agreater

Child restraint systems
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.
Should the 000F000Bindicator lamp not
illuminat eorgoo ut while the restraint is
installed, please chec kinstallation.
Periodically check the 000F000Bindicator
lamp while drivin gtomake sure the 000F
000B indicator lamp is illuminated. If the
000F000Bindicator lamp goes out or
remain sout, do not transport achild on the 60
