Advanced Airbag System components
The front passenger seat in your veh icle has a lot of very important
parts o f the A dvanced A irbag System in it. These p arts incl ude t he
we ight-sens ing mat, sensors, wiring, brackets, and more. The func
t ion o f the sys tem in t he front passenger sea t is che cked by the elec
tron ic contro l unit when the ignit ion is on . The contro l unit mo nitors
t he Advanced Air bag System and t urns the airbag indica tor ligh t on
when a malfunction in t he system compone nts is detected. The func
tion of the a irbag indicator light is descr ibed in greater detail be low. Because the front passenger seat co
nta ins important parts of t he
Adv anced Ai rbag System, you mus t tak e ca re to p reve nt i t from be ing
damaged . Damage to the seat may p revent the Advanced A irbag for
the front passenge r seat from do ing its job in a crash .
The front Advanced Airbag System consists of the
following:
• Cras h sensors in the front of the ve hicle tha t meas ure vehicle
acc elera tion/de ce le ra tion to prov ide info rm ation to the Advanced
Airbag System about the severity of the crash .
• An e lec tron ic contro l unit, w it h i ntegr ate d crash sensors fo r front
and side i mpacts . The control unit "dec ides" w het her to fire the front
airbags based o n the information rece ived from the c rash sensors .
T he contro l unit also "decides" whether the safety be lt prete nsioners
should be activated.
• An Advanced Airbag with gas generator fo r the driver inside the
s teer in g wheel hub.
• An Advanced Airbag with gas generator inside the instrument
p ane l for the front p assenge r.
• A weight-sensi ng mat under the upho lstery padd ing of the front
passenge r seat cushion that measu res the tota l we ight on the se at.
The informat ion registered is sent continuously to the electronic

ment Safety first Vehicle operation
& WARNING
(co ntinued )
• Never use cushions , pillows, blankets or similar items on the
front passenger seat . The additional padding will prevent the
weight-sensing mat in the seat from accurately registering the
c hild restraint or person on the seat and prevent the Advanced
Airbag System from functioning prope rly.
• If you must use a child restraint on the front passenger seat
and the child restraint manufacturer's instructions require the use
of a towel, foam cushion or something else to properly pos ition
the child restraint, make certain that the PASSENGER AIR BAG
OFF light come s on and stays on whenever the child re straint is
installed on the front passenger seat.
• If the PASSENGER AIR BAG OFF light does not come on and
stay on, immediately install child restraint in a rear seating posi

How the Advanced Airbag System
components work together
Th e fron t Advanced A irbag System and t he side airbags sup plemen t
the protect ion offered by the front three-po int safety belts with
prete nsioners and load limiters a nd t he adjusta ble head restra ints to
help reduce the risk of i njur y in a w ide range of acc ident and crash
situ ati ons. Be sure to re ad the important info rmat io n a bou t safe ty
and heed the WAR NINGS in this chapte r.
Deployment of the Adv a need Airbag System and the a ct iva tion of t he
sa fety belt pretens ioners depend on the dece leration measured by
the c rash sensors and reg istered by the e lectron ic contro l un it. Crash
sever ity depe nds on speed and deceleration as well as the mass and
st iffness of t he ve hicle or object invo lved in the crash.
Whe n the ele ct ronic con tro l u nit r egi sters a low sever ity crash and
the safety be lt is being used, the airbag will not dep loy . If the safety
bel t is not being used, the fi rs t st age de ploys, followed by the second
stage after a much later time in the crash seq uence. IJ,,

More important things to know about front
airbags
Fi g. 1 83 Infl ate d
front a irb ags
Safety belts are important to he lp keep front seat occupants in the
pro per seated pos ition so that a irbags can unfold prope rly and
prov ide supp lemental protect ion in a frontal collision.
Th e front airbags are designed to provide add itio na l protec tion for
the c hest and face of the driver and the front sea t passenge r when:
• safety belts are worn properly,
• t he seats have been posit ioned so that the occupant is prope rly
seated as far as possible from the airbag,
• and the head restraints have been properly adjusted .
Because air bags inflate in the b link of a n eye w it h great force, things
you have on your lap o r have place d on the seat cou ld become
dangerous projectiles, and be pushed into you if the a irbag inf lates.
When a n airbag dep loys, fine dust is released. This is normal and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to l ubricate t he ai rbags as they deploy.
It could irritate
skin .
It is important to remember that while the supp lemental airbag
system is desig ned to red uce the li ke lihood of serious injur ies, other
injuries, for example swelling, b ruising and m inor abras ions, can also
happen when airbags infl ate. Airbags do not p rotect the arms or the ..,_

lower parts of the body . Front a irbags s upplement the t hree-poi nt
sa fety belts o nly in some fro ntal collis ions in which the vehicle decel
eration is high enough to dep loy the a irbags .
Front airbags will not deploy:
• if the ignition is switched off when a crash occurs,
• in s ide collisions ,
• in rea r-end collisions,
• in rollovers,
• when the crash decelerat io n me asured by the a irbag system is less
than the min imum threshold needed for a irbag deployment as reg is
tered by the e lectron ic con trol un it.
The front passenger airbag also will not deploy:
• when the fron t passe nger seat i s not oc cupied,
• when the weight on the front passenger seat as sensed by the
Advanced Ai rbag System in dicates that the front airbag o n the
passenger side has to be turned off by the e lectronic control unit (the
PASSENGER AIR BAG OFF li ght comes on and stays on).
& WARNING
Sitting in the wrong position can increase the ri sk of ser iou s injury
in crashes.
• To redu ce the risk of injury when the airbags inflate, the driver
and pas sengers mu st always sit in an upright position , mu st not
lean against or place any part of th eir body too close to the area
where the airbags are lo cated.
• Occupants who are unbelted, out of position or too close to the
airbag can be seriou sly injured by an airbag a s it unfolds with
great force in th e blink of an eye =>

& WARNING
The fine dust created when airbags deploy can cause breathing
problems for people with a history of asthma or other br eathing
conditions.
• To reduce the risk of breathing problems, those with asthma or
other respiratory conditions should get fresh air right away by
getting out of the veh icle or opening windows or doors.
• If you are in a colli sion in which airbags deploy, wa sh your
hands and face with mild soap and water before eating .
• Be careful not to get the dust into your eyes, or into any cuts or
