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

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 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.
