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-Benz vehi-cle. The child restraint system must be appro-priate to the age, weight and size of the child.
Ralways observe the instructions and safetynotes on "Children in the vehicle"(Ypage 54) in addition to the child restraintsystem manufacturer's installation and oper-ating instructions
Ralways observe the instructions and safetynotes on the "Occupant classification system(OCS)". (Ypage 47)
GWARNING
The seat belts may not perform their intended
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 modi-
fied.
Seat belts may be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. Modified or damaged
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 approved foryour 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, the restraint
system cannot provide the best level of protec-tion.
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 42).
All vehicle occupants must be wearing the seatbelt correctly before beginning the journey. Alsomake sure that all vehicle occupants are alwayswearing the seat belt correctly while the vehicleis in motion.
When fastening the seat belt, always make surethat:
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 appropriate height.
Rthe lap belt is taut and passes across your lapas low down as possible
The lap belt must always be routed acrossyour hip joints and not across your abdomen.This applies particularly to pregnant women.If necessary, push the lap belt down to yourhip joint and pull it tight using the shouldersection of the belt.
Rthe seat belt is not routed across sharp, poin-ted or fragile objects
If you have such items located on or in yourclothing, e.g. pens, keys or eyeglasses, storethese in a suitable place.

Infants and children must never travel sittingon the lap of a vehicle occupant. In the eventof 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 of thevehicle's occupants
Also ensure that there are never objectsbetween a person and the seat, e.g. cushions.
Seat belts are only intended to secure andrestrain vehicle occupants. Always observe the"Loading guidelines" for securing objects, lug-gage or loads (Ypage 239).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt(Ypage 42) and the notes on correct use of seatbelts (Ypage 43).

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 warningtone sounds. A warning tone also sounds withincreasing intensity for 60 seconds or until thedriver or front passenger have fastened theirseat belts.
If the driver or front passenger unfasten theirseat belts during the journey, the seat belt warn-ing is activated again.
Air bags
Introduction
The installation point of an air bag can be rec-ognized by the AIRBAG marking.
An air bag complements the correctly fastenedseat belt. It is no substitute for the seat belt. Theair bag provides additional protection in appli-cable accident situations.
Not all air bags are deployed in an accident. Thedifferent air bag systems function independ-ently from one another (Ypage 52).
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 air bag due to the high speed atwhich the air bag 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 great-
est 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.
RAdjust the seats properly before beginningyour journey. Always make sure that the seatis in an almost upright position. The center ofthe head restraint must support the head atabout eye level.
RMove the driver's and front-passenger seatsas far back as possible. The driver's seat posi-tion must allow the vehicle to be driven safely.
ROnly hold the steering wheel on the outside.This allows the air bag 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 be inthe deployment area of the air bags.
RAlways keep your feet in the footwell in frontof the seat. Do not put your feet on the dash-board, for example. Your feet may otherwisebe in the deployment area of the air bag.
RFor this reason, always secure persons lessthan 5 ft (1.50 m) tall in suitable restraint sys-tems. Up to this height, the seat belt cannotbe worn correctly.
If a child is traveling in your vehicle, alsoobserve the following notes:
RAlways secure children under twelve years ofage and less than 5 ft (1.50m)tall in suitablechild restraint systems.
RChild restraint systems should be installed onthe rear seats.
ROnly secure a child in a rearward-facing childrestraint system on the front-passenger seatwhen the front-passenger front air bag isdeactivated. If the PASSENGER AIR BAG OFFindicator lamp is permanently lit, the front-passenger front air bag is deactivated(Ypage 41).
RAlways observe the instructions and safetynotes on the "Occupant Classification System(OCS)" (Ypage 47) and on "Children in thevehicle" (Ypage 54) in addition to the childrestraint system manufacturer's installationand operating instructions.

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 operation 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 outer bol-ster of the seat backrest.
When deployed, the side impact air bag offersadditional thorax protection. It also offers addi-tional pelvis protection for occupants in thefront seats. However, it does not protect the:
RHead
RNeck
RArms
If the restraint system control unit detects a sideimpact, the side impact air bag is deployed onthe side on which the impact occurs.
The side impact air bag on the front-passengerside deploys under the following conditions:
Rthe OCS system detects that the front-passenger seat is occupied or
Rthe seat belt buckle tongue is engaged in thebelt buckle of the front-passenger seat
If the belt tongue is engaged in the belt buckle,the side impact air bag on the front-passengerside deploys if an appropriate accident situationoccurs. In this case, deployment is independentof whether the front-passenger seat is occupiedor not.
Window curtain air bags
Window curtain air bagsCare integrated intothe side of the roof frame and deployed in thearea from the A-pillar to the C-pillar.
When deployed, the window curtain air bagenhances the level of protection for the head.However, it does not protect the chest or arms.
If the restraint system control unit detects a sideimpact, the window curtain air bag is deployedon the side on which the impact occurs.
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 52).
Occupant Classification System
(OCS)
Introduction
The Occupant Classification System (OCS) cat-egorizes the person in the front-passenger seat.Depending on that result, the front-passengerfront air bag and front-passenger knee bag areeither enabled or deactivated.
The system does not deactivate:

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 possible
If the front passenger does not observe theseconditions, OCS may produce a false classifica-tion, 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, besure to observe the correct positioning of thechild restraint system. Never place objectsunder or behind the child restraint system, e.g. acushion. The entire base of the child restraintsystem must always rest on the seat cushion ofthe front-passenger seat. The backrest of theforward-facing child restraint system must lie asflat as possible against the backrest 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 restraint sys-tem manufacturer's installation and operatinginstructions.

RPASSENGER AIR BAG ON lights up for 60 sec-onds, subsequently both indicator lamps areoff (PASSENGER AIR BAG ON and OFF): thefront-passenger front air bag is able to deployin the event of an accident.
RPASSENGER AIR BAG OFF lights up: the front-passenger front air bag is deactivated. It willthen not be deployed in the event of an acci-dent.
If the PASSENGER AIR BAG ON indicator lamp isoff, only the PASSENGER AIR BAG OFF indicatorlamp shows the status of the front-passengerfront air bag. The PASSENGER AIR BAG OFFindicator lamp may be lit continuously or be off.
If the status of the front-passenger front air bagchanges while the vehicle is in motion, an air bagdisplay message appears in the instrument clus-ter (Ypage 202). When the front-passengerseat is occupied, always pay attention to thePASSENGER AIR BAG OFF indicator lamp. Beaware of the status of the front-passenger frontair bag both before and during the 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 example, come
into contact with the vehicle's interior, espe-
cially 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-
48Occupant safety
Safety

passenger front air bag is enabled or disa-
bled 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 AIR-
BAG 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 childrestraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant Classification Sys-tem" (Ypage 51).
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 system self-test andremains lit. This indicates that the front-passenger front air bag is deactivated.
RThe front-passenger seat is occupied by achild of up to twelve months old, in a standardchild restraint system, the PASSENGER AIRBAG OFF indicator lamp lights up after thesystem self-test and remains lit. This indi-cates that the front-passenger front air bag isdeactivated.
But even in the case of a twelve-month-oldchild, in a standard child restraint system, thePASSENGER AIR BAG OFF indicator lamp cango out after the system self-test. This indi-cates that the front-passenger front air bag isactivated. The result of the classification isdependent on, among other factors, the childrestraint system and the child's stature. It isrecommended that you install the childrestraint system on a suitable rear seat.
RThe front-passenger seat is occupied by aperson of smaller stature (e.g. a teenager orsmall adult), the PASSENGER AIR BAG OFFindicator lamp lights up and remains lit afterthe system self-test depending on the resultof the classification or, alternatively, goes out.
-If the PASSENGER AIR BAG OFF indicatorlamp is off, move the front-passenger seat

as far back as possible. Alternatively, a per-son of smaller stature can sit on a rear seat.
-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 adult stature, thePASSENGER AIR BAG OFF indicator lampgoes out after the system self-test. This indi-cates that the front-passenger front air bag isactivated.
If children are traveling in the vehicle, be sure toobserve the notes on "Children in the vehicle"(Ypage 54).
When the Occupant Classification System(OCS) is malfunctioning, the redurestraintsystem warning lamp on the instrument clusterand the PASSENGER AIR BAG OFF indicatorlamp 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 a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose.
If the front-passenger seat, the seat cover or theseat cushion are damaged, have the necessaryrepair work carried out at a qualified specialistworkshop. Mercedes-Benz recommends thatyou use an authorized Mercedes-Benz Centerfor this purpose.
For safety reasons, Mercedes-Benz recom-mends that you only use seat accessories thathave been approved by Mercedes-Benz.
If the driver's air bag deploys, this does notmean that the front-passenger front air bag willalso deploy. The Occupant Classification Sys-tem (OCS) categorizes the occupant on thefront-passenger seat. Depending on that result,the front-passenger front air bag is either ena-bled or deactivated.
Self-check
GDANGER
If the PASSENGER AIR BAG OFF and
PASSENGER AIR BAG ON indicator lamps do
not both light up during the self-test, the sys-
tem is malfunctioning. The front-passenger
front air bag might be triggered unintention-
ally or might not be triggered at all in the event
of an accident with high deceleration. This
poses an increased risk of injury or even fatal
injury.
In this case the front-passenger seat may not
be used. Do not install a child restraint system
on the front-passenger seat. Have the Occu-
pant Classification System (OCS) checked
and repaired immediately at a qualified spe-
cialist workshop.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp remains lit after the self-test, the front-
passenger front air bag is deactivated. It will
not be deployed in the event of an accident. In
this case, the front-passenger front air bag
cannot perform its intended protective func-
tion, e.g. when a person is seated in the front-
passenger seat.
That person could, for example, come into
contact with the vehicle's interior, especially
if the person is sitting too close to the dash-
board. 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 deac-
tivated in accordance with the person in the
front-passenger seat
Rthe person is seated properly with a cor-
rectly fastened seatbelt
Rthe front-passenger seat has been moved
as far back as possible
If the PASSENGER AIR BAG OFF indicator
lamp remains lit when it should not, the front-
passenger seat must not be used. Do not
install a child restraint system on the front-
passenger seat. Have the Occupant Classifi-
cation System (OCS) checked and repaired
immediately at a qualified specialist work-
shop.

Deployment of Emergency Tensioning
Devices and air bags
Important safety notes
GWARNING
The air bag parts are hot after an air bag has
been deployed. There is a risk of injury.
Do not touch the air bag parts. Have a
deployed air bag replaced at a qualified spe-
cialist workshop as soon as possible.
GWARNING
A deployed air bag no longer offers any pro-
tection and cannot provide the intended pro-
tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified special-
ist workshop in order to have a deployed air
bag replaced.
It is important for your safety and that of yourpassenger to have deployed air bags replaced
52Occupant safety
Safety

and to have any malfunctioning air bagsrepaired. This will help to make sure the air bagscontinue to perform their protective function forthe vehicle occupants in the event of a crash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer opera-
tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a
qualified specialist workshop.
If Emergency Tensioning Devices are triggeredor air bags are deployed, you will hear a bang,and some powder may also be released. Theurestraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-ing. The powder that is released generally doesnot constitute a health hazard, but it may causeshort-term breathing difficulties in people withasthma or other respiratory problems. Providedit is safe to do so, you should leave the vehicleimmediately or open the window in order to pre-vent breathing difficulties.
Air bags and pyrotechnic Emergency TensioningDevices (ETDs) contain perchlorate material,which may require special handling and regardfor the environment. National guidelines mustbe observed during disposal. In California, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, the restraintsystem control unit evaluates important physi-cal data relating to vehicle deceleration or accel-eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluation of this data, therestraint system control unit triggers the Emer-gency Tensioning Devices during a head-on orrear-end collision.
An Emergency Tensioning Device can only betriggered, if:
Rthe ignition is switched on
Rthe components of the restraint system areoperational. You can find further informationunder "Restraint system warning lamp"(Ypage 41)
Rthe seat belt buckle tongue has engaged inthe belt buckle of the respective front seat
The Emergency Tensioning Devices in the rearpassenger compartment are triggered inde-pendently of the lock status of the seat belts.
If the restraint system control unit detects amore severe accident, further components ofthe restraint system are activated independ-ently of each other in certain frontal collisionsituations:
RFront air bags as well as driver's and front-passenger knee bags
RWindow curtain air bag, if the system deter-mines that deployment can offer additionalprotection to that provided by the seat belt
Depending on the person in the front-passengerseat, the front-passenger front air bag is eitherdisabled or enabled. The front-passenger frontair bag can be deployed in an accident only if thePASSENGER AIR BAG OFF indicator lamp is off.Observe the information on the PASSENGER AIRBAG indicator lamps (Ypage 41).
Your vehicle has two-stage front air bags. At thefirst deployment threshold the front air bag fillswith gas. If the second deployment threshold isthen reached within a few milliseconds, the frontair bag is filled with the maximum quantity ofgas.
The activation threshold of the Emergency Ten-sioning Devices and the air bags is determinedby evaluating the rate of vehicle deceleration oracceleration which occurs at various points inthe vehicle. This process is pre-emptive innature. Deployment should take place in goodtime at the start of the collision.
The rate of vehicle deceleration or accelerationand the direction of the force are essentiallydetermined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehicle
Rthe characteristics of the object with whichthe vehicle has collided
Factors which can only be seen and measuredafter a collision has occurred do not play a deci-

sive role in the deployment of an air bag. Nor dothey provide an indication of air bag deploy-ment.
The vehicle can be deformed considerably, with-out an air bag being deployed. This is the case ifonly parts which are relatively easily deformedare affected and the rate of deceleration is nothigh. Conversely, air bags may be deployed eventhough the vehicle suffers only minor deforma-tion. This is the case if, for example, very rigidvehicle parts such as longitudinal body mem-bers are hit, and sufficient deceleration occursas a result.
If the restraint system control unit detects a sideimpact or if the vehicle rolls over, the applicablecomponents of the restraint system aredeployed independently of each other depend-ing on the apparent type of accident.
RSide impact air bags on the side where theimpact takes place, independently of theEmergency Tensioning Device and the use ofthe seat belt on the driver's seat and outerseats in the second row

iNot all air bags are deployed in an accident.The different air bag systems work independ-ently of each other.
How the air bag system works is determinedby the severity of the accident detected,especially the vehicle deceleration or accel-eration and the apparent type of accident:
RHead-on collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the followingmeasures are implemented, depending on thetype and severity of the impact:
Rthe hazard warning lamps are switched on
Rthe emergency lighting is activated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rthe engine is switched off and the fuel supplyis cut off
Rvehicles with Mercedes me connect: auto-matic emergency call
Children in the vehicle
Important safety notes
Accident statistics show that children securedin the rear seats are safer than children securedin the front-passenger seat. For this reason,Mercedes-Benz strongly advises that you installa child restraint system on a rear seat. Childrenare generally better protected there.
If a child younger than twelve years old andunder 5 ft (1.50 m) in height is traveling in thevehicle:
Ralways secure the child in a child restraintsystem suitable for Mercedes-Benz vehicles.The child restraint system must be appropri-ate to the age, weight and size of the child.
Rbe sure to observe the instructions and safetynotes in this section in addition to the childrestraint system manufacturer's installationinstructions.
Ralways observe the instructions and safetynotes on the "Occupant classification system(OCS)". (Ypage 47)
