GWARNING
The seat belts may not perform their inten-
ded protective function if:
Rthey are damaged, modified, extremely
dirty, bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been
modified.
Seat belts may be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. Modified or dam-
aged seat belts may tear or fail, e.g. in an
accident. Modified Emergency Tensioning
Devices could accidentally trigger or fail to
deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages and inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-
shop.
Only use seat belts that have been approvedfor your vehicle by Mercedes-Benz.
Proper use of the seat belts
Observe the safety notes on the seat belt(Ypage 42).
Every vehicle occupant must observe the fol-lowing notes to ensure a properly worn seatbelt can provide full protection. Also makesure that all vehicle occupants are alwayswearing the seat belt correctly while the vehi-cle is in motion.
When fastening the seat belt, always makesure that:
Rthe seat belt buckle tongue is inserted onlyinto the belt buckle belonging to that seat
Rthe seat belt is pulled tight across your body
Avoid wearing bulky clothing, e.g. a wintercoat.
Rthe seat belt is not twisted
Only then can the forces which occur be dis-tributed over the area of the belt.
Rthe shoulder section of the belt is routedacross the center of your shoulder
The shoulder section of the seat belt shouldnot touch your neck or be routed under yourarm or behind your back.
Rthe lap belt is taut and passes across yourlap as low down as possible
The lap belt must always be routed acrossyour hip joints and not across your abdo-men. This applies particularly to pregnantwomen. If necessary, push the lap belt downto your hip joint and pull it tight using theshoulder section of the belt.
Rthe seat belt is not routed across sharp,pointed or fragile objects
If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses,store these in a suitable place.
Ronly one person is using a seat belt
Infants and children must never travel sit-ting on the lap of a vehicle occupant. In theevent of an accident, they could be crushedbetween the vehicle occupant and seat belt.
Robjects are never secured with a seat belt ifthe seat belt is also being used by one ofthe vehicle's occupants
Also ensure that there are never objectsbetween a person and the seat, e.g. cush-ions.
Seat belts are only intended to secure andrestrain vehicle occupants. Always observe thenotes in the "Stowage options/compartments"

passenger seat belts are not fastened, a warn-ing tone sounds. A warning tone also soundswith increasing intensity for 60 seconds oruntil the driver or front passenger have fas-tened their seat belts.
If the driver or front passenger unfasten theirseat belts during the journey, the seat beltwarning is activated again.
Air bags
Introduction
The installation point of an airbag can be rec-ognized by the AIRBAG marking.
An airbag complements the correctly fastenedseat belt. It is no substitute for the seat belt.When deployed, an airbag can increase theprotection provided for the respective vehicleoccupant.
Not all airbags are deployed in an accident.The various airbags work independently ofeach other (Ypage 53).
However, no system available today can com-pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injurycaused by an airbag due to the high speed atwhich the airbag must be deployed.
Important safety notes
GWARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
Rhave fastened their seat belts correctly,
including pregnant women
Rare sitting correctly and maintain the
greatest possible distance to the air bags
Rfollow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
All vehicle occupants must observe the follow-ing notes to avoid risks posed by the airbagwhen it deploys.
RAdjust the seats properly before beginningyour journey. Always make sure that theseat is in an almost upright position. Thecenter of the head restraint must supportthe head at about eye level.
RMove the driver's and front-passenger seatsas far back as possible. The driver's seatposition must allow the vehicle to be drivensafely.
ROnly hold the steering wheel on the outside.This allows the airbag to be fully deployed.
RAlways lean against the backrest while driv-ing. Do not lean forward or lean against thedoor or side window. You may otherwise bein the deployment area of the airbags.
RAlways keep your feet in the footwell infront of the seat. Do not put your feet on thedashboard, for example. Your feet may oth-erwise be in the deployment area of the air-bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraintsystems. Up to this height, the seat beltcannot be worn correctly.
If a child is traveling in your vehicle, alsoobserve the following notes:
RAlways secure children under twelve yearsof age and less than 5 ft (1.50 m) tall in suit-able child restraint systems.
RSecure a child to the front-passenger seatonly when the front-passenger front airbagis deactivated, and then only in a rearward-facing child restraint system. The front-passenger front airbag is deactivated whenthe PASSENGER AIR BAG OFF indicatorlamp is lit continuously (Ypage 41).
RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 48) and on "Childrenin the vehicle" (Ypage 57) in addition tothe child restraint system manufacturer'sinstallation and operating instructions.
Objects in the vehicle interior may restrictthe airbag from functioning correctly.Toavoid risks resulting from the speed of the air-bag as it deploys, vehicle occupants mustensure the following points.
