How The Airbag System Works
²
TheAirbag Control Module (ACM)determines if a
frontal collision is severe enough to require the airbags
to inflate. Based on the level of collision severity, the
front control module determines the proper rate of
inflation. The front airbag inflators are designed to
provide different rates of airbag inflation.
²The ACM, along with the remote side impact sensors
detects side impact.
²The ACM will not detect roll over, or rear impacts.
²The ACM monitors the readiness of the electronic
parts of the system whenever the ignition switch is in
the START or ON positions. These include all of the
items listed above except the steering wheel and
column and the knee bolsters. If the key is in the OFF
position, in the ACC position, or not in the ignition,
the airbags are not on and will not inflate.Also, the ACM turns on the AIRBAG warning light in
the instrument panel for 6 to 8 seconds when the
ignition is first turned on, then turns the light off. If it
detects a malfunction in any part of the system, it turns
on the light either momentarily or continuously.
WARNING!
Ignoring the AIRBAG warning light in your instru-
ment panel could mean you won't have the airbags
to protect you in a collision. If the light does not
come on, stays on after you start the vehicle, or if it
comes on as you drive, have the airbag system
checked right away.
²TheDriver and Passenger Airbag/Inflator Unitsare
located in the center of the steering wheel and the right
side of the instrument panel. When the ACM detects a
collision requiring the airbags, it signals the inflator

enough for an adult seat belt. Always check the child seat
owner's manual to ensure you have the right seat for
your child. Use the restraint that is correct for your child:
²The rearward-facing infant restraint is for babies
weighing up to about 20 lbs (9 kg), and one year old or
more. The infant restraint mustNEVERbe used in the
front seat of a vehicle with a passenger side airbag
unless the airbag is turned off. An airbag deployment
could cause severe injury or death to infants in this
position. The infant restraint is held in the vehicle by
the lap belt, lap/shoulder belt, or the LATCH child
restraint anchorage system. Refer to ªLower Anchors
and Tether for CHildren (LATCH)º in this section.
²Children under one year of age should continue to ride
in a rear-facing infant seat, even if they weigh more
than 20 lbs (9 kg). A ªconvertibleº child seat, one that
is designed to be used either rearward-facing orforward-facing, should be used for children who are
too heavy for the infant carrier, but who are too young
to face forward in the vehicle.
²The forward-facing child seat is for children from
about 20 lbs (9 kg) to 40 lbs (18 kg), and more than one
year old. The child seat is held in the vehicle by the lap
belt, lap/shoulder belt, or the LATCH child restraint
anchorage system. Refer to ªLower Anchors and
Tether for CHildren (LATCH)º in this section.
²The belt-positioning booster seat is for children weigh-
ing more than 40 lbs (18 kg). If the child cannot sit with
knees bent over the seat cushion while the child's back
is against the seat back, they should use a belt-
positioning booster seat. The child and booster seat are
held in the vehicle by the lap/shoulder belt. (Some
booster seats are equipped with a front shield and are
held in the vehicle by the lap portion or lap belt.)
