belts
Introduction Seat
belts arethe most effective meansof
restrict ingthe movement ofvehicle occupants
in the event ofan accident orthe vehicle roll-
ing over. Thisreduces therisk ofvehicle occu-
pants coming intocontactwith parts ofthe
vehicle interior orbeing ejected fromthevehi-
cle. Furthermore, theseat belthelps tokeep
the vehicle occupant inthe best position in
relation tothe airbag.
The seat beltsystem comprises:
R Seat belts
R Emergenc yTensioning Devicesforthe front
seat belts andtheouter seatbelts inthe
rear
R Seat beltforce limiters forthe front seat
belts andtheouter seatbelts inthe rear
If the seat beltispull edout ofthe belt outlet
quickly orwith ajerky movement, thebelt
retractor locks.Thebelt strap cannot be
extract edany further.
The Emergenc yTensioning Devicetightens the
seat beltinan accident, pulling the belt close
agai nstthe body. However itdoes notpull the
vehicle occupant backinthe direction ofthe
backrest.
The Emergenc yTensioning Devicedoesnot
correct anincorrect seatposition orthe rout-
ing ofan incorrect lyfastened seatbelt.
When triggered, aseat beltforce limiter helps
to reduce theforce exerted bythe seat belton
the vehicle occupant.
The seat beltforce limiters forthe front seats
are synchronized withthefront airbags, which
absorb partofthe deceleration force.Thiscan
reduce theforce exerted onthe vehicle occu-
pants during anaccident.
! If
the front -passenger seatisnot occupied,
do not engage theseat belttongue inthe
buckle onthe front -passenger seat.Other-
wise, inthe event ofan accident theEmer-
gency Tensioning Deviceandtheside impact
airbag, inaddition toother systems,
may betriggered andhave tobe replaced.

R the seat beltbuckle tongue isengaged in
the belt buckle ofthe front passenger seat
If the belt tongue isengaged inthe belt
buckle, theside impact airbag onthe front
passenger sidedeploys ifan appropriate acci-
dent situation occurs.Inthis case, deployment
is independent ofwhether thefront passenger
seat isoccupied ornot .

Classification System
(OCS)
Introdu ction The
Occupant Classification System(OCS)cat-
egorizes theperson inthe front -passenger
seat. Dependin gon that result, thefront - passenger
frontairbag and front -passenger
knee bagareeither enabled ordeactivated.
The system doesnotdeactivate:
R the side impact airbag
R the window curtainairbag
R the Emergen cyTensionin gDevices
Requir ements To
be classified correctly,the front passenger
must sit:
R with theseat beltfasten edcorrec tly
R in an almost upright position withtheir back
against theseat backrest
R with their feetrestin gon the floor, ifpossi-
ble
If the front passenger doesnotobserve these
condit ions,OCSmayproduce afalse classifi-
cation, e.g.because thefront passenger:
R trans ferstheir weight bysupporting them-
selves onavehicle armrest
R sits insuch away that their weight israised
from theseat cushion
If it is absolutely necessarytoinstall achild
restr aintsystem onthe front -passenger seat,
