Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-cle occupants coming into contact with parts ofthe vehicle's interior in the event of an accident.The restraint system can also reduce the forcesto which vehicle occupants are subjected duringan accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing systems
The components of the restraint system work inconjunction with each other. They can onlydeploy their protective function if, at all times, allvehicle occupants:
Rhave fastened their seat belts correctly(Ypage 43)
Rhave the seat and head restraint adjustedproperly (Ypage 91)
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 91).
You also have to make sure that an air bag caninflate properly if deployed (Ypage 45).
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. For exam-ple, if, in the event of an accident, the protectionoffered by the seat belt is sufficient, the air bagsare not deployed. When an accident occurs, onlythe air bags that increase protection in that par-ticular accident situation are deployed. How-ever, seat belts and air bags generally do notprotect against objects penetrating the vehiclefrom the outside.
Information on restraint system operation canbe found under "Triggering of the EmergencyTensioning Devices and air bags" (Ypage 52).
See "Children in the vehicle" for information onchildren traveling with you in the vehicle as wellas on child restraint systems (Ypage 54).
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.
If it is necessary to modify components of therestraint system to accommodate a person withdisabilities, contact an authorized Mercedes-Benz Center for details. USA only: for furtherinformation contact our Customer AssistanceCenter at 1-800 FOR-MERCEDES(1‑800‑367‑6372).
Mercedes-Benz recommends that you only usedriving aids which have been approved specifi-cally for your vehicle by Mercedes-Benz.

Restraint system warning lamp
The functions of the restraint system arechecked after the ignition is switched on and atregular intervals while the engine is running.Therefore, malfunctions can be detected ingood time.
Theurestraint system warning lamp on theinstrument cluster lights up when the ignition isswitched on. It goes out no later than a few sec-onds after the vehicle is started. The compo-nents of the restraint system are in operationalreadiness.
A malfunction has occurred if theurestraintsystem warning lamp:
Rdoes not light up after the ignition is switchedon
Rdoes not go out after a few seconds with theengine running
Rlights up again while the engine is running
GWARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. This poses an increased
risk of injury or even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lampCandPASSENGER AIR BAG OFF indicator lampDarepart of the Occupant Classification System(OCS).
The indicator lamps display the status of thefront-passenger front air bag.
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.
Depending on the person in the front-passengerseat, the front-passenger front air bag musteither be deactivated or enabled; see the fol-lowing points. You must make sure of this bothbefore and during a journey.
RChildren in a child restraint system:whether the front-passenger front air bag isenabled or deactivated depends on the instal-led child restraint system, and the age andsize of the child. Therefore, be sure to observethe notes on the "Occupant ClassificationSystem (OCS)" (Ypage 47) and on "Chil-dren in the vehicle" (Ypage 54). There youwill also find instructions on rearward andforward-facing child restraint systems on thefront-passenger seat.
RAll other persons:depending on the classi-fication of the person in the front-passengerseat, the front-passenger front air bag is ena-bled or deactivated (Ypage 47). Be sure toobserve the notes on "Seatbelts“ (Ypage 41) and "Air bags"(Ypage 45). 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 rollingover. This reduces the risk of vehicle occupantscoming into contact with parts of the vehicleinterior or being ejected from the vehicle. Fur-thermore, the seat belt helps to keep the vehicle
Occupant safety41

occupant in the best position in relation to theair bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the frontseat belts and the outer seat belts in the rear
RSeat belt force limiters for the front seat beltsand 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 be extrac-ted 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 not cor-rect an incorrect seat position or the routing ofan incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps toreduce the force exerted by the seat belt on thevehicle occupant.
The seat belt force limiters for the front seats aresynchronized 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 impactair bag, in addition to other systems, may betriggered and have to be replaced.
Important safety notes
The use of seat belts and child restraint systemsis 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 vehicleoccupants should correctly fasten their seatbelts before starting the journey.
GWARNING
If the seat belt is not worn correctly, it cannot
perform 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.
Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit-
ting properly.
The components of the restraint system work inconjunction with each other. They can onlydeploy their protective function if, at all times, allvehicle occupants:
Rhave fastened their seat belts correctly(Ypage 43)
Rhave the seat and head restraint adjustedproperly (Ypage 91)
GWARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
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 (1.50 m) 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 (1.50 m) tall in suitable additional restraint
systems.
42Occupant 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-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.
Ronly one person is using a seat belt

seconds or once the driver's seat belt is fas-tened.
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.
