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.
1-58Safety—Seats, seat belts and supplemental restraint system

∙ Do not make unauthorized changesto your vehicle’s electrical system,
suspension system or side panel. This
could affect proper operation of the
side air bag and curtain air bag
systems.
∙ Tampering with the side air bag sys- tem may result in serious personal in-
jury. For example, do not change the
front and rear seats by placing mate-
rial near the seatbacks or by installing
additional trim material, such as seat
covers, around the side air bag.
∙ It is recommended that you visit a NISSAN dealer for work on and around
the side air bag and curtain air bag. It
is also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. The SRS wiring har-
nesses* should not be modified or dis-
connected. Unauthorized electrical
test equipment and probing devices
should not be used on the side air bag
or curtain air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion. When selling your vehicle, we request that
you inform the buyer about the side air bag
and curtain air bag systems and guide the
buyer to the appropriate sections in this
Owner’s Manual.
Driver and passenger
supplemental knee air bag
The knee air bag is located in the knee
bolster, on the driver’s and passenger’s
side.
All of the information, cautions and
warnings in this manual apply and must
be followed. The knee air bag is designed
to inflate in higher severity frontal collisions,
although it may inflate if the forces in an-
other type of collision are similar to those of
a higher severity frontal impact. It may not
inflate in certain collisions.

Safety—Seats, seat belts and supplemental restraint system1-61

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.
