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

units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, these rates are determined by the front
airbag control module based on collision severity. The
steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the
way as the bags inflate to their full size. The bags fully
inflate in about 30±70 milliseconds. This is about half
of the time it takes to blink your eyes. The bags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver front airbag gas is vented through the
airbag material towards the instrument panel. The
passenger front airbag gas is vented through the
airbag material on the sides of the airbag. In this way,
the airbags do not interfere with your control of the
vehicle.²TheSide Impact SRS Window Bagsare designed to
activate only in certain side collisions. When the airbag
control module (ACM), along with the remote side
impact sensors detects a side impact collision requir-
ing the window bags to inflate, it signals the inflators
on the crash side of the vehicle. A quantity of nontoxic
gas is generated to inflate the window bag. The
inflating window bag pushes the outside edge of the
headliner out of the way and covers the window. The
airbag inflates in about 30 milliseconds (about one
quarter of the time it takes to blink your eyes) with
enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies
to children. The window bag is only about 3
1¤2inches
(9 cm) thick when it is inflated.
²TheKnee Impact Bolstershelp protect the knees of
the driver and the front passenger's, and position
everyone for the best interaction with the front airbag.

Exterior Mirrors Folding Feature
All exterior mirrors are hinged and may be moved either
forward or rearward to resist damage. The hinges have
three detent positions; full forward, full rearward, and
normal.
Outside Mirrors
To receive maximum benefit, adjust the outside mirrors
to center on the adjacent lane of traffic with a slight
overlap of the view obtained on the inside mirror.
WARNING!
Vehicles and other objects seen in the right side
convex mirror will look smaller and farther away
than they really are. Relying too much on your right
side mirror could cause you to collide with another
vehicle or other objects. Use your inside mirror when
judging the size or distance of a vehicle seen in the
right side mirror.
Heated Remote Control Mirrors Ð If Equipped
These mirrors are heated to melt frost or ice. This
feature is activated whenever you turn on the rear
window defrost.
Power Remote Control Outside Mirrors
The controls for the power mirrors are located on the
driver's door trim panel above the window switches.
