may become dangerous projec-
tiles and cause injury if the front
air bags inflate.
. Do not place objects with sharp
edges on the seat. Also, do not
place heavy objects on the seat
that will leave permanent impres-
sions in the seat. Such objects
can damage the seat or occupant
classification sensors (weight
sensors). This can affect the op-
eration of the air bag system and
result in serious personal injury.
. Do not use water or acidic clea-
ners (hot steam cleaners) on the
seat. This can damage the seat or
occupant classification sensors.
This can also affect the operation
of the air bag system and result in
serious personal injury.
. Immediately after inflation, sev-
eral front air bag system compo-
nents 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 supple-
mental air bag or damage to the
supplemental air bag system.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
front end structure. This could
affect proper operation of the
front air bag system.
. Tampering with the air bag sys-
tem may result in serious perso-
nal injury. Tampering includes
changes to the steering wheel
and the instrument panel assem-
bly by placing material over the

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 sides. All of the information, cau-
tions 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 another type of collision are
similar to those of a higher severity
frontal impact. It may not inflate in certain
collisions.
WAB0181X
Front passenger’s side
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 irritation and choking. Those with a
history of a breathing condition should
get fresh air promptly.
The knee air bag helps to cushion the
impact force on the knees of the driver
and front passenger. It can help reduce
serious injuries. 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
occupant is too close to, or is against,
this air bag module during inflation. The
knee air bag will deflate quickly after 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.
After 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 after about 7 seconds if the system
is operational.
WARNING
.Do not place any objects between
the knee bolster and the driver’s
or front passenger’s seat. Such
objects may become dangerous
projectiles and cause injury if a
knee air bag inflates. .
Right after 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 inflation of the knee
air bag system.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system or suspension system.
This could affect proper opera-
tion of the knee air bag system.
. Tampering with the knee air bag
system may result in serious per-
sonal injury. For example, do not
change the driver or front pas-
senger knee bolster or install
additional trim material around
the knee air bag.
. It is recommended that you visit a
NISSAN dealer for work on and
around the knee air bag. It is also
recommended that you visit a
NISSAN dealer for installation of
electrical equipment. The SRS
wiring harnesses* should not be
modified or disconnected. Un-
authorized electrical test equip- ment and probing devices should
not be used on the knee air bag
system.
*The SRS wiring harness or connectors
are yellow or orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the knee air
bag system and guide the buyer to the

FRONT SEAT-MOUNTED SIDE-IM-
PACT SUPPLEMENTAL AIR BAG AND
ROOF-MOUNTED CURTAIN SIDE-
IMPACT AND ROLLOVER SUPPLE-
MENTAL AIR BAG SYSTEMS
The side air bags are located in the
outside of the seatback of the front seats.
The curtain air bags are located in the
side roof rails.All of the information,
cautions and warnings in this manual
apply and must be followed. The side air
bags and curtain air bags are designed to
inflate in higher severity side collisions,
although they may inflate if the forces in
another type of collision are similar to
those of a higher severity side impact. They are designed to inflate on the side
where the vehicle is impacted. They may
not inflate in certain side collisions on the
side where the vehicle is impacted.
Curtain air bags are also designed to
inflate in certain types of rollover colli-
sions or near rollovers. As a result, certain
vehicle movements (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 side air bags and curtain air bags
inflate, 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 irritation and choking. Those
with a history of a breathing 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 pelvis of the front occu-
pants. Curtain air bags help to cushion
the impact force to the head of occu-
pants in the front and rear (2nd and 3rd)
outboard seating positions. They can help
save lives and reduce serious injuries.
However, an inflating side air bags and
curtain air bags may cause abrasions or
other injuries. Side air bags and curtain airbags do not provide restraint to the lower
body.
The seat belts should be correctly worn
and the driver and passenger 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 finishers 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 bags and curtain air bags
inflating can increase the risk of injury if
the occupant is too close to, or is against,
these air bag modules during inflation. In
a rollover, the curtain air bags on both
sides are designed to inflate. Under both
side-impact situations, the curtain air
bags will remain inflated for a short
period of time.
The side air bags and curtain air bags
operate only when the ignition switch is
in the ON position.
After placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The air bag
warning light will turn off after about 7
seconds if the systems are operational.

WARNING
.Do not place any objects near the
seatback of the front seats. Also,
do not place any objects (an
umbrella, bag, etc.) between the
front door finisher and the front
seat. Such objects may become
dangerous projectiles and cause
injury if side air bag inflates.
. Right after inflation, several side
air bags and curtain air bag sys-
tem 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 side air bag and curtain
air bags. This is to prevent da-
mage to or accidental inflation of
the side air bag and curtain air
bag systems.
. Do not make unauthorized
changes to your vehicle’s electri-
cal system, suspension system or
side panel. This could affect prop-
er operation of the side air bag
and curtain air bag systems.
. Tampering with the air bag sys-
tem may result in serious perso- nal injury. For example, do not
change the front seats by placing
material near the seatback or by
installing additional trim materi-
al, such as seat covers, around
the side air bags.
. Removing or modifying the front
passenger seat may affect the
function of the air bag system
and result in serious personal
injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the side air bag and
curtain air bag. It is also recom-
mended you visit a NISSAN dealer
for installation of electrical equip-
ment. The Supplemental Re-
straint System (SRS) wiring
harnesses* should not be modi-
fied or disconnected. Unauthor-
ized electrical test equipment
and probing devices should not
be used on the side-impact 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 sec-
tions in this Owner’s Manual.
SEAT BELTS WITH PRETENSIONERS
(front and second row outboard
seats)
WARNING
.
The pretensioners cannot be re-
used after activation. They must
be replaced together with the
retractor and buckle as a unit.
. If the vehicle becomes involved in
a collision but a pretensioner is
not activated, be sure to have the
pretensioner system checked
and, if necessary, replaced. It is
recommended you visit a NISSAN
dealer for this service.
. No unauthorized changes should
be made to any components or
wiring of the pretensioner sys-
tem. This is to prevent damage to
or accidental activation of the
pretensioners. Tampering with
the pretensioner system may re-
sult in serious personal injury.
. It is recommended you visit a
NISSAN dealer for work on and
around the pretensioner system.
Safety — seats, seat belts and supplemental restraint system1-71

1-72Safety — seats, seat belts and supplemental restraint system
It is also recommended you visit a
NISSAN dealer for installation of
electrical equipment. Unauthor-
ized electrical test equipment
and probing devices should not
be used on the pretensioner sys-
tem.
. If you need to dispose of a pre-
tensioner or scrap the vehicle, it is
recommended you visit a NISSAN
dealer for this service. Correct
pretensioner disposal procedures
are set forth in the appropriate
NISSAN Service Manual. Incorrect
disposal procedures could cause
personal injury.
The pretensioner system may activate
with the supplemental air bag system in
certain types of collisions. Working with
the seat belt retractor, it helps tighten the
seat belt when the vehicle becomes
involved in certain types of collisions,
helping to restrain front and second row
outboard seats occupants.
The pretensioner is encased with the seat
belt retractor and buckle anchor. These
seat belts are used the same way as
conventional seat belts.
When a pretensioner activates, smoke is
released and a loud noise may be heard.
The smoke is not harmful, and it does not indicate 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.
After pretensioner activation, load limiters
allow the seat belt to release webbing (if
necessary) to reduce forces against the
chest.
The supplemental air bag warning light
is used to indicate malfunctions in
the pretensioner system. (See “Supple-
mental air bag warning light” (P.1-73) for
more details.) If the operation of the
supplemental air bag warning light indi-
cates there is a malfunction, have the
system checked. It is recommended you
visit a NISSAN dealer for this service.
When selling your vehicle, we request that
you inform the buyer about the preten-
sioner system and guide the buyer to the
appropriate sections in this Owner’s Man-
ual.
