Airb a g syste m
- Always make sure the forward-facing seat
has been designed and ce rtified by its man-
ufacturer for use on a front seat with a pas-
senger front a nd side airbag.
- Never put the forward-facing child restraint
up against or very near the instrument pan-
el.
- Always move the front passenger seat to
t he highest position in the up and down ad-
justment range and move it back to th e
rea rmost position in the seat's fore and aft
adjustment range, as fa r away from the air-
bag as possib le, before insta lling the for-
ward-facing child restra int.
- lways make sure that the safety belt upper
anchorage is beh ind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi-
tioned.
- Always make sure that the re is nothing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signa l to the Airbag System that
the seat is occupied by a person when it is
not, or to signa l that it is occupied by some-
one who is heav ier than the person actua lly
sitting on the seat. The presence of addi-
tional objec t s could cause the passenge r
front airbag to be turned on when it s hou ld
be off, or could cause the airbag to work in a
way that is different from the way it would
have worked without the object on the seat.
- Make sure tha t the PASSENGER AIR BAG

Advanced Airbag System components
The front passenger seat in your vehicle has a lot
of very important parts of the Advanced Airbag
System in it. These parts include the capacitive
passenger detection system, wiring, brackets,
a nd mo re. The cont rol u nit monitors the system
on the front passenger seat when the ign ition is
sw itched on and t ur ns t he a irbag indicator light
on when a malf unct io n in t he o ne of t he system
components is detected ¢ page 193. Because
the front passenger seat contains important
188
parts of the Advanced Airbag System, you must
take care to prevent it from being damaged .
Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
do ing its job in a crash.
The front Advanced Airbag System consist s
of the following:
- Crash sensors in the front of the veh icle that
measure vehicle acce leration/dece leration to
prov ide information to the Advanced Airbag
System about the sever ity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts . The
cont rol u nit "dec ides" whether to fire the front
airbags based on the information rece ived from
the crash senso rs . The cont rol unit also "de-
cides" whe t her the safe ty belt pretensioners
should be activated .
- An Adva nce d Airbag wit h gas gene rat or for the
dr iver inside t he steeri ng wheel hub .
- An Advanced Airbag with gas gene rat or inside
t he inst rument pa nel for the fro nt passenge r.
- A capacit ive passenger detection system under-
neath t he front passenge r seat cover. This sys-
t em meas ures the e lect rical capaci t an ce of t he
person in the sea t. The information registered
is sent continuously to the electronic control
unit to reg ulate dep loyment of the front Ad-
vanced Airbag on the passenger side.
- An airbag monitoring system and indicator
light
El
in the instrument cluster.
- A sensor in each front seat registers the dis-
tance between the respective seat and the
steer ing wheel or instrument panel. The infor-
mation registe red is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced Airbags .
- The PASSENGER AIR BAG OFF
