154 Airbag sys te m
- Always make su re that t here is nothing
on the front passenger seat that will
cause the capacitive passenge r detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a
person when it is not, or to signal that it
is occ upied by someone who is heavier
than the person actu ally s itting on the
sea t. The presence of additiona l obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause the airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes o n and stays on all the
t ime whenever the ignition is switched
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l o t of very important pa rts of the Advanced
A irbag System in it. These parts incl ude the
capacitive passenger detect ion sys tem, wir­
ing, brac kets, and more . The cont ro l unit
monitors the system on the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on w hen a
malfunction i n the one of the system compo­
n ents is detected
c::;, page 159 . Because the
front passenge r seat contains important pa rts
of the Advanced Airbag System, you must
take ca re to pr even t it from be ing damaged.
Damage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front o f the veh icle that
measure ve hicle acceleration/dece leration
to provide information to the Advanced Air­ bag System abo ut the severity of the crash .
- An electronic co ntro l unit, with i ntegrated
c rash sensors for f ront and side impacts.
The cont ro l unit "decides" whether to fire t
he front a irbags based on the in format ion
received from the crash sensors. The contro l
un it also "decides" whether the sa fety belt
pretens ioners sho uld be activated.
- An Advanced Airbag with gas generator fo r
the dr iver inside the steering wheel hub.
- An Advanced Airbag with gas gene rator in­
side the inst rument panel for the front pas­
senger.
- A capacit ive passenger detection system un­
derneath the front passenger seat cover.
This system measures the electrical capac i­
tance of the person in the seat. The informa­
tion registered is se nt cont inuous ly to the
elect ronic control un it to regu late deploy­
ment of the front Advanced A irbag on the
passe nger side.
- An airbag monitor ing system and indicator
light in t he i nstr ument cluster
¢ page 158.
-A senso r in each front seat registers the dis­
tanc e between the r espective seat and the
s teer ing whee l o r ins trumen t panel. The in­
form ation regis tered is sent cont inuo usly to
t he ele ct ron ic cont ro l unit to regula te de­
p loyment of the front Adv a need Ai rbags.
- The
PASSENGER AIR BAG OFF ligh t comes
on and stays on in the cen ter o f the instr u­
ment panel
c::;, page 214 and tells you when
the front Advanced Airbag on the passenger
side has been turned off.
- A sensor in t he safety be lt latch fo r th e d riv­
er and for the front seat passenger that
senses whether that safety belt is latched or not and transmits this information to t he
electronic control un it .
A WARNING
--
D amage to the fron t passenger seat can
p rev ent the fro nt airbag from wor king
prop erly.
- I mp rope r re pa ir or disassembly of the
fr ont passenge r and dr ive r sea t will pre­
ven t th e Adv anced Air bag System from
functioning p ro perly.
- Repairs to the front pa ssenge r seat must
be pe rformed by qualifie d and properly
trained workshop personnel.

_& WARNING
An airbag system that is not functioning
properly cannot provide supplemental pro­
tection in a frontal crash.
- If the airbag indicator light¢

turns on when the vehicle is being used,
have the system inspected immediately
by you r auth o riz ed Aud i dea le r. It is pos­
sible that the airb ag will inf late when it
is not s upposed to, or w ill not inflate
when it sho uld .
