iontothe restr aintsystem
The restraint systemcanreduce therisk of
vehicle occupants comingintocontactwith
parts ofthe vehicle's interiorinthe event ofan
accident. Inthe event ofan accident, the
restraint systemcanalso reduce theforces to
which thevehicle occupants aresubjected.
The restraint systemincludes thefollowing
componen ts:
R Seat beltsystem
R Air bags
R Child restraint system
R Child seatsecuring systems The
componen tsof the restraint systemwork
in conj unction witheach other. Theycanonly
deploy theirprotect ivefunct ionif,at all times,
all vehicle occupants:
R have fastened theirseatbelts correct ly
(Y page 42)
R have theseat andhead restraint adjusted
properly (Ypage 92)
As the driver, youalso have tomake surethat
the steering wheelisadjusted correctly.
Observe theinformation relatingtothe correct
driver's seatposition (Ypage 92).
You also have tomake surethatanair bag can
inflate properly ifdeploye d(Y page 44).
An airbag supplements acorrect lyworn seat
belt. Asanadditional safetydevice, theairbag
increases thelevel ofprotect ionforvehicle
occupants inthe event ofan accident. For
example, if,inthe event ofan accident, the
protect ionoffered bythe seat beltissufficient,
the airbags arenot deploye d.When anacci-
dent occurs, onlytheairbags thatincrease
protect ioninthat particular accidentsituation
are deploye d.However, seatbelts andairbags
generally donot protect againstobjectspene-
tratin gthe vehicle fromtheoutside.

(Y page 51).

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.
Importa ntsafety notes The
useofseat belts andchild restraint sys-
tems isrequired bylaw in:
R all 50 states
R the U.S. territories
R the District ofColu mbia
R all Canadi anprovinces
Even where thisisnot required bylaw, allvehi-
cle occupants shouldcorrectlyfasten their
seat belts before starting thejourney. G
WARNING
If the seat beltisnot worn correct ly,itcan-
not perform itsintended protective function.
An incorrect lyfastened seatbeltcanalso
cause injuries, forexample, inthe event of
an accident orwhen braking orchanging
direction abruptly.This poses anincreased
risk ofinjury oreven fatalinjury.
Always ensurethatallvehicle occupants
have theirseatbelts fastened correctlyand
are sitting properly.
The component partsofthe restraint system
work inconj unction witheach other. Theycan
only deploy theirprotective functionif,at all
times, allvehicle occupants:
R have fastened theirseatbelts correct ly
(Y page 42)
R have theseat andhead restraint adjusted
properly (Ypage 92) G
WARNING
The seat beltdoes notoffer theintended
level ofprotection ifyou have notmoved the
backrest toan almost vertical position.
When braking orinthe event ofan accident,
you could slideunderneath theseat beltand
sustain abdomen orneck injuries, forexam-
ple. This poses anincreased riskofinjury or
even fatalinjury.
Adjust theseat properly beforebeginning
your journey. Alwaysensurethattheback-
