•Do not make unauthorized changes
to 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
injury. For example, do not change
the front and rear seats by placing
material near the seatbacks or by in-
stalling 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 installa-
tion of electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Unauthor-
ized 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
identification. 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 front passenger
supplemental knee air bag
The knee air bag is located in the knee
bolster, on the driver’s and front passen-
ger’s side.
All of the information, cautions
and warnings in this manual apply and
must be followed. The knee air bag is de-
signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another type of collision are simi-
lar to those of a higher severity frontal im-
pact. It may not inflate in certain collisions.

Vehicle damage (or lack of it) is not always
an indication of proper knee air bag
operation.
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
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 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
prevent damage to or accidental in-
flation 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
injury. For example, do not change
the driver or passenger knee bolster
or install additional trim material
around the knee air bag.

Seat belt with pretensioner(s)
(front and rear outboard seats)
WARNING
• The pretensioner(s) cannot be re-
used af ter activation. They must be
replaced together with the retractor
and buckle as a unit. •
If the vehicle becomes involved in a
collision but pretensioner(s) are not
activated, be sure to have the preten-
sioner system checked and, if neces-
sary, replaced. It is recommended
that you visit a NISSAN dealer for this
service.
• No unauthorized changes should be
made to any components or wiring
of the pretensioner system. This is to
prevent damage to or accidental ac-
tivation of the pretensioner(s). Tam-
pering with the pretensioner system
may result in serious personal injury.
• It is recommended that you visit a
NISSAN dealer for work on and
around the pretensioner system. It is
also recommended that you visit a
NISSAN dealer for installation of elec-
trical equipment. Unauthorized elec-
trical test equipment and probing
devices should not be used on the
pretensioner system.
• If you need to dispose of the preten-
sioner(s) or scrap the vehicle, it is rec-
ommended that you visit a NISSAN
dealer for this service. Incorrect dis-
posal procedures could cause per-
sonal injury. The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with the
seat belt retractor, the pretensioner(s) help
tighten the seat belt when the vehicle be-
comes involved in certain types of colli-
sions, helping to restrain front and rear out-
board seat occupants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt an-
chor affixed to the floor of the vehicle.
These seat belts are used the same way as
conventional seat belts.
When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. 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.
Af ter the pretensioner(s’) activation, load
limiters allow the seat belt to release web-
bing (if necessary) to reduce forces against
the chest.
