Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk ofvehicle occupants coming into contact withparts of the vehicle's interior in the event of anaccident. The restraint system can also reducethe forces to which vehicle occupants are sub-jected during an accident.
The restraint system includes the followingcomponents:
Rseat belt system
Rair bags
Rchild restraint system
Rchild seat securing systems
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)
As the driver, you also have to make sure thatthe steering wheel is adjusted correctly.Observe the information relating to the correctdriver's seat position (Ypage 92).
You also have to make sure that an air bag caninflate properly if deployed (Ypage 44).
An air bag supplements a correctly worn seatbelt. As an additional safety device, the air bagincreases the level of protection for vehicleoccupants in the event of an accident. Forexample, if, in the event of an accident, theprotection offered by the seat belt is sufficient,the air bags are not deployed. When an acci-dent occurs, only the air bags that increaseprotection in that particular accident situationare deployed. However, seat belts and air bagsgenerally do not protect against objects pene-trating the vehicle from the outside.
Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags"(Ypage 51).
See "Children in the vehicle" for informationon children traveling with you in the vehicle aswell as on child restraint systems(Ypage 53).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in
an accident or trigger unexpectedly, for
example. This poses an increased risk of
injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.

seat, the front-passenger front air bag isenabled or deactivated (Ypage 47). Besure to observe the notes on "Seatbelts“ (Ypage 41) and "Air bags"(Ypage 44). There you can also find infor-mation on the correct seat position.
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 indicator lamps inform you whether thefront-passenger front air bag is deactivated orenabled.
XPress the Start/Stop button once or twice,or turn the SmartKey to positionGorHinthe ignition lock.The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF andPASSENGER AIR BAG ON indicator lamps mustlight up simultaneously for approximately sixseconds.
The indicator lamps display the status of thefront-passenger front air bag.
RPASSENGER AIR BAG ON lights up for60 seconds, subsequently both indicatorlamps are off (PASSENGER AIR BAG ON andOFF): the front-passenger front air bag isable to deploy in the event of an accident.
RPASSENGER AIR BAG OFF lights up: thefront-passenger front air bag is deactivated.It will then not be deployed in the event ofan accident.
If the PASSENGER AIR BAG ON indicator lampis off, only the PASSENGER AIR BAG OFF indi-cator lamp shows the status of the front-passenger front air bag. The PASSENGER AIRBAG OFF indicator lamp may be lit continu-ously or be off.
If the status of the front-passenger front airbag changes while the vehicle is in motion, anair bag display message appears in the instru-ment cluster (Ypage 213). When the front-passenger seat is occupied, always pay atten-tion to the PASSENGER AIR BAG OFF indicatorlamp. Be aware of the status of the front-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 childrestraint system on the front-passenger seat.You can find more information on OCS under"Problems with the Occupant ClassificationSystem" (Ypage 51).

tection in an accident. There is an increased
risk of injury.
Have the vehicle towed to a qualified spe-
cialist 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 replacedand to have any malfunctioning air bagsrepaired. This will help to make sure the airbags continue to perform their protective func-tion for the vehicle occupants in the event of acrash.
GWARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer
operational and are unable to perform their
intended 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 yourhearing. The powder that is released generallydoes not constitute a health hazard, but it maycause short-term breathing difficulties in peo-ple with asthma or other respiratory problems.Provided it is safe to do so, you should leavethe vehicle immediately or open the window inorder to prevent breathing difficulties.
Air bags and pyrotechnic Emergency Tension-ing Devices (ETDs) contain perchlorate mate-rial, which may require special handling andregard for the environment. National guide-lines must be observed during disposal. In Cal-ifornia, seewww.dtsc.ca.gov/HazardousWaste/Perchlorate/index.cfm.
Method of operation
During the first stage of a collision, therestraint system control unit evaluates impor-tant physical data relating to vehicle decelera-tion or acceleration, 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 40)
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-passenger seat, the front-passenger front airbag is either enabled or disabled. The front-passenger front air bag can be deployed in anaccident only if the PASSENGER AIR BAG OFFindicator lamp is off. Observe the informationon the PASSENGER AIR BAG indicator lamps(Ypage 40).
Your vehicle has two-stage front air bags.
The activation threshold of the EmergencyTensioning Devices and the air bags is deter-mined by evaluating the rate of vehicle decel-eration or acceleration which occurs at variouspoints in the vehicle. This process is pre-emp-tive in nature. Deployment should take placein good time at the start of the collision.
52Occupant safety
Safety

The rate of vehicle deceleration or accelera-tion and the direction of the force are essen-tially determined by:
Rthe distribution of forces during the collision
Rthe collision angle
Rthe deformation characteristics of the vehi-cle
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 adecisive role in the deployment of an air bag.Nor do they provide an indication of air bagdeployment.
The vehicle can be deformed considerably,without an air bag being deployed. This is thecase if only parts which are relatively easilydeformed are affected and the rate of deceler-ation is not high. Conversely, air bags may bedeployed even though the vehicle suffers onlyminor deformation. This is the case if, forexample, very rigid vehicle parts such as longi-tudinal body members are hit, and sufficientdeceleration occurs as a result.
If the restraint system control unit detects aside impact or if the vehicle rolls over, theapplicable components of the restraint systemare deployed independently of each otherdepending on the apparent type of accident.
RSide impact air bags on the side where theimpact takes place, independently of theEmergency Tensioning Device and the useof the seat belt on the driver's seat andouter seats in the second row
The side impact air bag on the frontpassenger side deploys under the followingconditions:
-the OCS system detects that the frontpassenger seat is occupied or
-the seat belt buckle tongue is engaged inthe belt buckle of the front passengerseat

iNot all air bags are deployed in an acci-dent. The different air bag systems workindependently 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 sup-ply is cut off

Children in the vehicle
Important safety notes
Accident statistics show that children securedin the rear seats are safer than childrensecured in the front-passenger seat. For thisreason, Mercedes-Benz strongly advises thatyou install a child restraint system on a rearseat. Children are generally better protectedthere.
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 andsafety notes in this section in addition to the
Children in the vehicle53

child restraint system manufacturer's instal-lation instructions.
Ralways observe the instructions and safetynotes on the "Occupant classification sys-tem (OCS)". (Ypage 47)
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.
Observe the safety notes on the seat belt(Ypage 41) and the notes on correct use ofseat belts (Ypage 42).
A booster seat may be necessary to achieveproper seat belt positioning for children over40 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.
All seat belts in the vehicle, except the driver'sseat belt, are equipped with a special seat beltretractor. When activated, the special seat beltretractor ensures that the seat belt cannotslacken once the child seat is secured.
Installing a child restraint system:
XMake sure you observe the child restraintsystem manufacturer's installation instruc-tions.
XPull the seat belt smoothly from the beltoutlet.
XEngage seat belt tongue in belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertiareel retract it again.While the seat belt is retracting, you shouldhear a ratcheting sound. The special seatbelt retractor is enabled.
XPush the child restraint system down so thatthe seat belt is tight and does not loosen.
54Children in the vehicle
Safety

All child restraint systems must meet the fol-lowing standards:
RU.S. Federal Motor Vehicle Safety Standards213 and 225
RCanadian Motor Vehicle Safety Standards213 and 210.2
Confirmation that the child restraint systemcorresponds to the standards can be found onan instruction label on the child restraint sys-tem. This confirmation can also be found inthe installation instructions that are includedwith the child restraint system.
Observe the warning labels in the vehicle inte-rior and on the child restraint system.
LATCH-type (ISOFIX) child seat
securing system
GWARNING
For LATCH-type (ISOFIX) child restraint sys-
tems in which the child is secured using the
safety belt integrated in the child restraint
system, the maximum permissible weight of
the child and child restraint system together
is 73 lbs (33 kg).
If the child and the child restraint system
together weigh more than 73 lbs (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated safety belt no longer offers
sufficient protection. The LATCH-type (ISO-
FIX) child seat securing system may be over-
loaded, and the child may not be restrained
in an accident, for example. This poses an
increased risk of injury or even fatal injury.
If the child and the child restraint system
together weigh more than 73 lbs (33 kg),
use only a LATCH-type (ISOFIX) child
restraint system in which the child is also
secured with the vehicle seat belt. Also
secure the child restraint system with the
Top Tether belt, if available.
Regularly check that the permissible grossweight of the child together with the childrestraint system is still maintained.
Always comply with the manufacturer's instal-lation and operating instructions for the childrestraint system used.
Before every trip, make sure that the LATCH-type (ISOFIX) child restraint system is engagedcorrectly in both LATCH-type (ISOFIX) securingrings
!When installing the child restraint system,make sure that the seat belt for the middleseat does not get trapped. The seat beltcould otherwise be damaged.
XInstall the LATCH-type (ISOFIX) childrestraint system on both LATCH-type (ISO-FIX) securing ringsC.
LATCH-type (ISOFIX) is a standardized secur-ing system for specially designed childrestraint systems on the rear seats. LATCH-type (ISOFIX) securing rings for two LATCH-type (ISOFIX) child restraint systems are instal-led on the left and right of the rear seats.
Non-LATCH-type (ISOFIX) child seats may alsobe used and can be installed using the vehi-cle's seat belt system. Install the child seataccording to the manufacturer's instructions.
Top Tether
Introduction
Top Tether provides an additional connectionbetween the child restraint system securedwith a LATCH-type (ISOFIX) system and thevehicle. This helps reduce the risk of injuryeven further. If the child restraint system isequipped with a Top Tether belt, this shouldalways be used.

accident, heavy braking or sudden changes
of direction. As a result, child restraint sys-
tems cannot perform their intended protec-
tive function. Rear seat backrests that are
not locked can also cause additional inju-
ries, e.g. in the event of an accident. This
poses an increased risk of injury or even
fatal injury.
Always lock rear seat backrests after instal-
ling a Top Tether belt. Observe the lock veri-
fication indicator. Adjust the rear seat
backrests so that they are in an upright posi-
tion.
