Other supplemental front-impact air
bag precautions
WARNING
∙ Do not place any objects on the steer- ing wheel pad or on the instrument
panel. Also, do not place any objects
between any occupant and the steer-
ing wheel or instrument panel. Such
objects may become dangerous pro-
jectiles and cause injury if the front air
bags inflate.
∙ Immediately af ter inflation, several front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
∙ No unauthorized changes should be made to any components or wiring of
the supplemental air bag system. This
is to prevent accidental inflation of
the supplemental air bag or damage
to the supplemental air bag system. ∙ Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
∙ Tampering with the front air bag sys- tem may result in serious personal in-
jury. Tampering includes changes to
the steering wheel and the instru-
ment panel assembly by placing ma-
terial over the steering wheel pad and
above the instrument panel or by in-
stalling additional trim material
around the air bag system.
∙ Removing or modif ying the front pas- senger seat may affect the function of
the air bag system and result in seri-
ous personal injury.

though they may inflate if the forces in an-
other type of collision are similar to those of
a higher severity impact. They are de-
signed to inflate on the side where the ve-
hicle is impacted. They may not inflate in
certain side collisions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvic area of the front and
rear outboard occupants. Curtain air bags
help to cushion the impact force to the
head of occupants in the front and rearoutboard seating positions. They can help
save lives and reduce serious injuries. How-
ever, an inflating side air bag and curtain air
bag may cause abrasions or other injuries.
Side air bags and curtain air bags do not
provide restraint to the lower body.
The seat belts should be correctly worn
and the driver, front passenger and rear
outboard occupants seated upright as far
as practical away from the side air bag.
Rear seat passengers should be seated as
far away as practical from the door finish-
ers and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of
this, the force of the side air bag and curtain
air bag inflating can increase the risk of
injury if the occupant is too close to, or is
against, these air bag modules during in-
flation. The side air bag will deflate quickly
af ter the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags
operate only when the ignition switch is
placed in the ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
∙ Do not place any objects near the
seatback of the front and rear seats.
Also, do not place any objects (an um-
brella, bag, etc.) between the front
and rear door finisher and the front
and rear seat. Such objects may be-
come dangerous projectiles and
cause injury if a side air bag inflate.
∙ Right af ter inflation, several side air bag and curtain air bag system com-
ponents will be hot. Do not touch
them; you may severely burn yourself.
∙ No unauthorized changes should be made to any components or wiring of
the side air bag and curtain air bag
systems. This is to prevent damage to
or accidental inflation of the side air
bag and curtain air bag or damage to
the side air bag and curtain air bag
systems.
Safety—Seats, seat belts and supplemental restraint system1-63

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag opera-
tion.
When the knee air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. This smoke is not harmful and
does not indicate a fire. Care should be
taken not to inhale it, as it may cause irrita-
tion and choking. Those with a history of a
breathing condition should get fresh air
promptly.The knee air bag helps to cushion the im-
pact force on the knees of the driver and
passenger. It can help reduce serious inju-
ries. However, an inflating knee air bag may
cause abrasions or other injuries. The knee
air bag provides restraint to the lower body.
The knee air bag inflates quickly in order to
help protect the occupants. Because of
this, the force of the knee air bag inflating
can increase the risk of injury if the occu-
pant is too close to, or is against, this air bag
module during inflation. The knee air bag
will deflate quickly af ter the collision is over
OR the knee air bag will remain inflated for
a short time.
The knee air bag operates only when the
ignition switch is placed in the ON posi-
tion.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.
WARNING
∙ Do not place any objects between the
knee bolster and the driver’s or pas-
senger’s seat. Such objects may be-
come dangerous projectiles and
cause injury if a knee air bag inflates.
∙ Right af ter inflation, the knee air bag system components will be hot. Do
not touch them; you may severely
burn yourself.
∙ No unauthorized changes should be made to any components or wiring of
the knee air bag system. This is to pre-
vent damage to or accidental inflation
of the knee air bag system.
∙ Do not make unauthorized changes to your vehicle’s electrical system or
suspension system. This could affect
proper operation of the knee air bag
system.
∙ Tampering with the knee air bag sys- tem may result in serious personal in-
jury. For example, do not change the
driver or passenger knee bolster or
install additional trim material
around the knee air bag.
