Introduction

the vehicle occupant in the best position inrelation to the air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices and seat beltforce limiters
If the seat belt is pulled quickly or sharply bythe seat belt guide, the inertia reel locks. Thebelt strap cannot be extracted any further.
The Emergency Tensioning Device tightens theseat belt in an accident, pulling the belt closeagainst the body. However it does not pull thevehicle occupant back in the direction of thebackrest.
The Emergency Tensioning Device does notcorrect an incorrect seat position or the rout-ing of an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helpsto reduce the force exerted by the seat belt onthe vehicle occupant.
The seat belt force limiters are synchronizedwith the front air bags which absorb part ofthe deceleration force. This can reduce theforce exerted on the vehicle occupants duringan accident.
!If the front-passenger seat is not occupied,do not engage the seat belt tongue in thebuckle on the front-passenger seat. Other-wise, in the event of an accident the Emer-gency Tensioning Device and the sideimpact air bag, in addition to other systems,may be triggered and have to be replaced.
Important safety notes
The use of seat belts and child restraint sys-tems is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehi-cle occupants should correctly fasten theirseat belts before starting the journey.
GWARNING
If the seat belt is not worn correctly, it can-
not perform its intended protective function.
An incorrectly fastened seat belt can also
cause injuries, for example, in the event of
an accident or when braking or changing
direction abruptly. This poses an increased
risk of injury or even fatal injury.
Always ensure that all vehicle occupants
have their seat belts fastened correctly and
are sitting properly.
The components of the restraint system workin conjunction with each other. They can onlydeploy their protective function if, at all times,all vehicle occupants:
Rhave fastened their seat belts correctly(Ypage 41)
Rhave the seat and head restraint adjustedproperly (Ypage 85)
GWARNING
The seat belt does not offer the intended
level of protection if you have not moved the
backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the back-
rest is in an almost vertical position and that
the shoulder section of your seat belt is
routed across the center of your shoulder.
GWARNING
Persons less than 5 ft (1.50m)tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of
injury or even fatal injury.
For this reason, always secure persons
under 5 ft (1.50m)tall in suitable additional
restraint systems.
40Occupant safety
Safety

If a child younger than twelve years old andunder 5 ft (1.50m)in height is traveling in thevehicle:
Ralways secure the child in a child restraintsystem suitable for this Mercedes-Benzvehicle. The child restraint system must beappropriate to the age, weight and size ofthe child.
Ralways observe the instructions and safetynotes on "Children in the vehicle"(Ypage 53) in addition to the childrestraint system manufacturer's installationand operating instructions
Ralways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 46)
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 40).
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"

If the vehicle's speed exceeds 15 mph(25 km/h) once and the driver's and front-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 50).
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 39).
RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 46) and on "Childrenin the vehicle" (Ypage 53) 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.

passenger front air bag both before and duringthe journey.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag
is disabled. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for exam-
ple, come into contact with the vehicle's
interior, especially if the person is sitting too
close to the dashboard. This poses an
increased risk of injury or even fatal injury.
When the front-passenger seat is occupied,
always ensure that:
Rthe classification of the person in the
front-passenger seat is correct and the
front-passenger front air bag is enabled or
disabled in accordance with the person in
the front-passenger seat
Rthe front-passenger seat has been moved
back as far back as possible.
Rthe person is seated correctly.
Make sure, both before and during the jour-
ney, that the status of the front-passenger
front air bag is correct.
GWARNING
If you secure a child in a rearward-facing
child restraint system on the front-
passenger seat and the PASSENGER AIR
BAG OFF indicator lamp is off, the front-
passenger front air bag can deploy in the
event of an accident. The child could be
struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been deactivated. The PASSENGER
AIR BAG OFF indicator lamp must be lit.
NEVER use a rearward-facing child restraint
on a seat protected by an ACTIVE FRONT
AIRBAG in front of it; DEATH or SERIOUS
INJURY to the child can occur.
If the PASSENGER AIR BAG OFF indicator lampstays off, do not install a rearward-facing child
restraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant ClassificationSystem" (Ypage 49).
GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat
too close to the dashboard, in the event of
an accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the
PASSENGER AIR BAG OFF indicator lamp
is off
This poses an increased risk of injury or
even fatal injury.
Move the front-passenger seat as far back
as possible. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt guide to the shoulder belt
guide on the child restraint system. The
shoulder belt strap must be routed forwards
and downwards from the vehicle belt guide.
Always observe the child restraint system
manufacturer's installation instructions.
If OCS determines that:
RThe front-passenger seat is unoccupied, thePASSENGER AIR BAG OFF indicator lamplights up after the self-test and remains lit.This indicates that the front-passenger frontair bag is deactivated.
RThe front-passenger seat is occupied by achild of up to twelve months old, in a stand-ard child restraint system, the PASSENGERAIR BAG OFF indicator lamp lights up afterthe self-test and remains lit. This indicatesthat the front-passenger front air bag isdeactivated.
But even in the case of a twelve-month-oldchild, in a standard child restraint system,the PASSENGER AIR BAG OFF indicatorlamp can go out after the self-test. This indi-cates that the front-passenger front air bagis activated. The result of the classificationis dependent on, among other factors, thechild restraint system and the child's stat-

GWARNING
If you leave children unsupervised in the
vehicle, they could set it in motion by, for
example:
Rrelease the parking brake.
Rshift the automatic transmission out of
the parking positionP.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
GWARNING
If persons, particularly children are subjec-
ted to prolonged exposure to extreme heat
or cold, there is a risk of injury, possibly
even fatal. Never leave children unattended
in the vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before secur-
ing the child in it. Never leave children unat-
tended in the vehicle.
Always ensure that all vehicle occupants havetheir seat belts fastened correctly and are sit-ting properly. Particular attention must be paidto children.

A booster seat may be necessary to achieveproper seat belt positioning for children over
40 lbs (18 kg) until they reach a height wherea three-point seat belt can be properly fas-tened without a booster seat.
Special seatbelt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real
draws in a portion of the seat belt. The seat
belt cannot be immediately refastened.
There is an increased risk of injury, possibly
even fatal.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions. Reacti-
vate the special seat belt retractor and
secure the child restraint system properly.
