Airb a g syste m
g reater detail below. Because the front passen -
ger seat contains important parts of the Ad-
vanced Airbag System, you must take care to pre -
vent it from being damaged. Damage to the seat
may prevent the Advanced Airbag for the front
passenger seat from doing its job in a crash .
The front Advanced Airbag System consis ts
of the follo wi ng :
- Crash sensors in the front of the vehicle that
measure vehicle acceleration/deceleration
to
provide information to the Advanced Airbag
System about the seve rity of the crash .
- An electronic control un it, with integrated
crash sensors for front and side impacts . The
contro l unit "decides " whethe r to fire the front
airbags based on the information received from
the crash sensors. The control unit a lso "de-
cides" whether the safety be lt pretensioners
shou ld be activated.
- An Advanced Airbag with gas generator and
contro l valve for the driver ins ide the steering
whee l hub .
- An Advanced Airbag with gas generator and
contro l valve inside the instrument pane l for
the front passenger .
- A weight -sensing mat under the upho lstery
padding of the front passenger seat cushion
that measures th e total weight on the seat . The
information registered is sent continuously to
the e lect ronic control unit to regu late dep loy-
ment of the front Advanced Airbag on the pas -
senger side .
- An airbag monitoring system and indica t or
light in the instrument cluster

- A sensor in each front sea t registers the dis-
tance between the respective seat and the
steering wheel or instrument panel. The infor-
mation reg istered is sent continuous ly to the
electronic control unit to regulate deployment
of t he front Advanced Airbags.
- The PASSENGER AIR BAG OFF light comes on
and stays on in the center of the inst rument
pane l

and tells you when
the front Advanced Airbag on the passenger
side has been turned off .
- A sensor below the safety belt lat ch fo r the
front seat passenger to meas ure the tension on

the safety belt. The tension on the safety belt
and the weight reg istered by the weight-sens-
ing mat help the contro l unit "decide" whether
the front airbag for the front passenger seat
should be turned
off
or not

things to know .
- A sensor in the safety belt latch for the driver
