doing its job in a crash.
The front Advanced Airbag System consists
of th e follo wing :
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration to
provide information to the Advanced Airbag
System a bout the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
contro l unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors . The control unit also "de-
cides" whether the safety belt pretens ioners
shou ld be activated .
- An Advanced Airbag with gas generator for the
dr iver inside the steering wheel hub.
- An Advanced Airbag with gas generator ins ide
the instrument panel for the front passenger.
- A capac itive passenger detect io n system under-
neath the front passenger seat cover. This sys-
tem measures the elect rical capac ita nce of the
person in the seat. The info rmat ion registe red
is sent cont inuous ly t o the electro nic cont rol
unit to regula t e deployment of t he front Ad-
vanced Airbag on the passenge r side.
- An a irbag monito ring system and indica t or
ligh t in the ins t rument cluste r ¢
page 281 .
- A se nso r in eac h front seat reg isters the dis -
tance between the respec t ive sea t and t he
steering wheel or instrument pane l. The infor -
mation registered is sent continuous ly to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel ¢ page 318 and tells you when the front
Advanced Airbag on the passenger side has
been turned off .
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
