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
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 43)
Rhave the seat and head restraint adjustedproperly (Ypage 97)
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 97).
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. 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 53).
See "Children in the vehicle" for informationon children traveling with you in the vehicle aswell as on child restraint systems(Ypage 57).
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 personwith disabilities, contact an authorizedMercedes-Benz Center for details. USA only:for further information contact our CustomerAssistance Center 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.
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 57) 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 48)
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 42).
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"

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 headbag
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 you install a child restraint system on thefront-passenger seat, be sure to observe thecorrect positioning of the child restraint sys-tem. Never place objects under or behind thechild restraint system, e.g. a cushion. Fullyretract the seat cushion length. The entirebase of the child restraint system must alwaysrest on the seat cushion of the front-passenger seat. The backrest of the forward-facing child restraint system must lie as flat aspossible 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 restraintsystem manufacturer's installation and operat-ing instructions.

Rbe sure to observe the instructions andsafety notes in this section in addition to thechild restraint system manufacturer's instal-lation instructions.
Ralways observe the instructions and safetynotes on the "Occupant classification sys-tem (OCS)". (Ypage 48)
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

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 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.
