Seat belts
Introduction
Seat belts are the most effective means ofrestricting the movement of vehicle occupantsin the event of an accident or the vehicle roll-ing over. This reduces the risk of vehicle occu-pants coming into contact with parts of thevehicle interior or being ejected from the vehi-cle. Furthermore, the seat belt helps to keepthe vehicle occupant in the best position inrelation to the air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the frontseat belts and the outer seat belts in therear
RSeat belt force limiters for the front seatbelts and the outer seat belts in the rear
If the seat belt is pulled out of the belt outletquickly or with a jerky movement, the beltretractor locks. The belt strap cannot beextracted 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 for the front seatsare synchronized with the front air bags, whichabsorb part of the deceleration force. This canreduce the force exerted on the vehicle occu-pants during an 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 side
impact 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 42)
Rhave the seat and head restraint adjustedproperly (Ypage 92)
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.
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 47)
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.
Sports seat or AMG Performance seat:thisseat is designed for the standard three-pointseat belt. If you install another multi-point seatbelt, e.g. sport or racing seat belts, therestraint system cannot provide the best levelof protection.
GWARNING
If you feed seat belts through the opening in
the seat backrest, the seat backrest may be
damaged or may even break in the event of
an accident. This poses an increased risk of
injury or even fatal injury.
Only use the standard three-point seat belt.
Never modify the seat belt system.
Proper use of the seat belts
Observe the safety notes on the seat belt(Ypage 41).
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. Where possible,adjust the seat belt to the appropriateheight.
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 the"Loading guidelines" for securing objects, lug-gage or loads (Ypage 250).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt(Ypage 41) and the notes on correct use ofseat belts (Ypage 42).

Belt warning for the driver and front
passenger
Thevseat belt warning lamp in the instru-ment cluster is a reminder that all vehicleoccupants must wear their seat belts. It maylight up continuously or flash. In addition,there may be a warning tone.
Regardless of whether the driver's seat belthas already been fastened, thevseat beltwarning lamp lights up for six seconds eachtime the engine is started. If the front doorsare closed and the driver's or front-passengerseat belt has not been fastened, thevseatbelt warning lamp lights up again after the sixseconds. As soon as the driver's and front-passenger seat belts are fastened or a frontdoor is opened again, thevseat belt warn-ing lamp goes out.
If the driver's seat belt is not fastened afterthe engine is started, an additional warningtone will sound. The warning tone switches offafter six seconds or once the driver's seat beltis fastened.
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 51).
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 restraint

systems. 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 (1.50m)tall in suit-able child restraint systems.
RChild restraint systems should be installedon the rear seats.
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 40).
RAlways observe the instructions and safetynotes on the "Occupant Classification Sys-tem (OCS)" (Ypage 47) 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.
Before commencing your journey, ensure that:
Rthere are no people, animals or objectsbetween the vehicle occupants and an air-bag
Rthere are no objects between the seat, doorand B-pillar
Rthere are no hard objects, e.g. coat hangers,hanging on the grab handles or coat hooks
Rno accessories, such as cup holders, areattached to the vehicle within the deploy-ment area of an airbag, e.g. to doors, sidewindows, rear side trim or side walls
Rno heavy, sharp-edged or fragile objects arein the pockets of your clothing. Store suchobjects in a suitable place
GWARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
GWARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or
door paneling carried out at a qualified spe-
cialist workshop.
Front air bags
!Do not place heavy objects on the front-passenger seat. This could cause the sys-tem to identify the seat as being occupied.In the event of an accident, the restraintsystems on the front-passenger side may betriggered and have to be replaced.
Driver's air bagCdeploys in front of thesteering wheel. Front-passenger front airbagDdeploys in front of and above the glovebox.
When deployed, the front air bags offer addi-tional head and thorax protection for the occu-pants in the front seats.
The PASSENGER AIR BAG OFF indicator lampinforms you about the status of the front-passenger front air bag (Ypage 40).
The front-passenger front air bag will onlydeploy if:
Rthe system, based on the OCS weight sen-sor readings, detects that the front-

Knee bags
Driver's knee bagCdeploys under the steer-ing column and front-passenger knee bagDunder the glove box. The driver's and front-passenger knee bags are triggered togetherwith the front air bags.
The driver's and front-passenger knee bagsoffer additional thigh, knee and lower leg pro-tection for the occupants in the front seats.
Side impact air bags
GWARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they
are designed to do. In addition, the opera-
tion of the occupant classification system
(OCS) could be adversely affected. This
poses an increased risk of injury or even
fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bagsCand rear sideimpact air bagsDdeploy next to the outerbolster of the seat backrest.
When deployed, the side impact air bag offersadditional thorax protection. It also offersadditional pelvis protection for occupants inthe front seats. However, it does not protectthe:
Rhead
Rneck
Rarms
If the restraint system control unit detects aside impact, the side impact air bag isdeployed on the side on which the impactoccurs.
The side impact air bag on the front passengerside deploys under the following conditions:
Rthe OCS system detects that the frontpassenger seat is occupied or
Rthe seat belt buckle tongue is engaged inthe belt buckle of the front passenger seat
If the belt tongue is engaged in the beltbuckle, the side impact air bag on the frontpassenger side deploys if an appropriate acci-dent situation occurs. In this case, deploymentis independent of whether the front passengerseat is occupied or not.

When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest orarms.
If the restraint system control unit detects aside impact, the window curtain air bag isdeployed on the side on which the impactoccurs.
If the system determines that they can offeradditional protection to that provided by theseat belt, a window curtain air bag may bedeployed in other accident situations(Ypage 51).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passengerseat. Depending on that result, the front-passenger front air bag and front-passengerknee bag are either enabled or deactivated.
The system does not deactivate:
Rthe side impact air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
Requirements
To be classified correctly, the front passengermust sit:
Rwith the seat belt fastened correctly
Rin an almost upright position with their backagainst the seat backrest
Rwith their feet resting on the floor, if possi-ble
If the front passenger does not observe theseconditions, OCS may produce a false classifi-cation, e.g. because the front passenger:
Rtransfers their weight by supporting them-selves on a vehicle armrest
Rsits in such a way that their weight is raisedfrom the seat cushion
If it is absolutely necessary to install a childrestraint system on the front-passenger seat,be sure to observe the correct positioning ofthe child restraint system. Never place objectsunder or behind the child restraint system, e.g.a cushion. The entire base of the childrestraint system must always rest on the seatcushion of the front-passenger seat. The back-rest of the forward-facing child restraint sys-tem must lie as flat as possible against thebackrest of the front-passenger seat.
The child restraint system must not touch theroof or be subjected to a load by the headrestraint. Adjust the angle of the seat backrestand the head restraint position accordingly.
Only then can OCS be guaranteed to functioncorrectly. Always observe the child restraintsystem manufacturer's installation and operat-ing instructions.

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.
Always move the front-passenger seat as far
back as possible and fully retract the seat
cushion length. Always make sure that the
shoulder belt strap is correctly routed from
the vehicle belt sash 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 sash
guide. If necessary, adjust the vehicle belt
sash guide and the front-passenger seat
accordingly. 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-
ure. It is recommended that you install thechild restraint system on a suitable rearseat.
RThe front-passenger seat is occupied by aperson of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp either lights up and remainslit after the self-test depending on the resultof the classification or, alternatively, goesout.
-If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seatas far back as possible. Alternatively, aperson of smaller stature can sit on a rearseat.
-If the PASSENGER AIR BAG OFF indicatorlamp is lit, a person of smaller statureshould not use the front-passenger seat.
RThe front-passenger seat is occupied by anadult or a person of corresponding stature,the PASSENGER AIR BAG OFF indicatorlamp goes out after the self-test. This indi-cates that the front-passenger front air bagis activated.
If children are traveling in the vehicle, be sureto observe the notes on "Children in the vehi-cle" (Ypage 53).
When the Occupant Classification System(OCS) is malfunctioning, the redurestraintsystem warning lamp on the instrument clus-ter and the PASSENGER AIR BAG OFF indica-tor lamp light up simultaneously. The front-passenger front air bag is deactivated in thiscase and does not deploy during an accident.Have the Occupant Classification System(OCS) checked and repaired immediately at aqualified specialist workshop. Mercedes-Benzrecommends that you use an authorizedMercedes-Benz Center for this purpose.
If the front-passenger seat, the seat cover orthe seat cushion are damaged, have the nec-essary repair work carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose.
For safety reasons, Mercedes-Benz recom-mends that you only use seat accessories thathave been approved by Mercedes-Benz.
Deployment of the driver's air bag does notmean that the front-passenger front air bagdeploys as well. The Occupant ClassificationSystem (OCS) categorizes the occupant on thefront-passenger seat. Depending on that
