PRECAUTIONS ON
SUPPLEMENTAL RESTRAINT
SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the driver and passenger supplemental front air
bags and pre-tensioner seat belts.
Supplemental front impact air bag system:
This system can help cushion the impact force to
the head and chest of the driver and front pas-
senger in certain frontal collisions.
The supplemental air bags are designed to
supplementthe crash protection provided by
the driver and front passenger seat belts and are
not a substitutefor them. Seat belts should
always be correctly worn and the driver and front
passenger seated a suitable distance away from
the steering wheel and instrument panel. (See
“Seat belts” later in this section for instructions
and precautions on seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

WARNING
cThe supplemental front air bags ordi-
narily will not inflate in the event of a
side impact, rear impact, rollover, or
lower severity frontal collision. Always
wear your seat belts to help reduce the
risk or severity of injury in various kinds
of accidents.cThe seat belts and the supplemental
front air bags are most effective when
you are sitting well back and upright in
the seat. The front air bags inflate with
great force. If you are unrestrained,
leaning forward, sitting sideways or out
of position in any way, you are at
greater risk of injury or death in a crash.
You may also receive serious or fatal
injuries from the supplemental front air
bag if you are up against it when it
inflates. Always sit back against the
seatback and as far away as practical
from the steering wheel or instrument
panel. Always use the seat belts.cThe driver and front passenger seat belt
buckles are equipped with sensors that
detect if the seat belts are fastened. The
air bag system monitors the severity of
a collision and then inflates the air bags
based on belt usage. Failure to properly
wear seat belts can increase the risk or
severity of injury in an accident.
cKeep hands on the outside of the steer-
ing wheel. Placing them inside the
steering wheel rim could increase the
risk that they are injured when the
supplemental front air bag inflates.

WARNING
cChildren may be severely injured or
killed when the supplemental front air
bags inflate if they are not properly re-
strained. Pre-teens and children should
be properly restrained in the rear seat, if
available.cNever install a rear-facing child re-
straint in the front seat of a model
equipped with a supplemental air bag
ON/OFF switch unless you first turn
OFF the air bag. An inflating supple-
mental air bag could seriously injure or
kill your child. See “Child restraints”
later in this section for details.

The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box.These systems are designed to meet optional
certification requirements under U.S. regulations.
They are also permitted in Canada. The optional
certification allows the front air bags to be de-
signed to inflate somewhat less forcefully than
previously.However, all of the information,
cautions and warnings in this manual still
apply and must be followed.
The supplemental front air bag system is de-
signed to inflate in higher severity frontal colli-
sions, 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 frontal collisions. Vehicle damage (or lack
of it) is not always an indication of proper supple-
mental front air bag system operation.
King Cab models are equipped with a supple-
mental front passenger air bag ON/OFF switch.
Because no rear seat exists where a rear facing
child restraint can be secured as in other models,
the switch is designed to turn OFF the passenger
supplemental air bag so that a rear facing child
restraint can be used in the front passenger seat.
See “Passenger supplemental air bag ON/OFF
switch and light” later in this section for details.
Crew Cab models are not equipped with a
supplemental front passenger air bag ON/OFF
switch because they have a rear seat for child
restraint installation. Further, for Crew Cab mod-

els, the supplemental air bag system has dual
stage inflators for both the driver and passenger
air bags. The system monitors information from
the crash zone sensor, the diagnosis sensor unit
and seat belt buckle sensors that detect if the
seat belts are fastened. Inflator operation is
based on the severity of a collision and whether
the seat belts are being used. Only one front air
bag may inflate in a crash, depending on the
crash severity and whether the front occupants
are belted or unbelted. This does not indicate
improper performance of the system. If you have
any questions about the performance of your air
bag system, please contact your NISSAN dealer.
When the supplemental front air bag inflates, a
fairly loud noise may be heard, followed by the
release of smoke. This smoke is not harmful and
does not indicate a fire. Care should be taken to
not inhale it, as it may cause irritation and chok-
ing. Those with a history of a breathing condition
should get fresh air promptly.
Supplemental front air bags, along with the use of
seat belts, help to cushion the impact force on
the face and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air bags
do not provide restraint to the lower body.Seat belts should be correctly worn and the
driver and passenger seated upright as far as
practical away from the steering wheel or instru-
ment panel. The supplemental front air bags in-
flate quickly in order to help protect the front
occupants. Because of this, the force of the front
air bag inflating can increase the risk of injury if
the occupant is too close to, or is against, the
front air bag module during inflation.
The front air bags deflate quickly after a collision.
The supplemental front air bags operate
only when the ignition switch is in the ON
or START position.
After turning the ignition key to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.
WARNING
cDo 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 steering
wheel or instrument panel. Such ob-
jects may become dangerous projec-
tiles and cause injury if the supplemen-
tal front air bag inflates.cImmediately after inflation, several
front air bag system components will be
hot. Do not touch them; you may se-
verely burn yourself.
cNo 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.
cDo not make unauthorized changes to
your vehicle’s electrical system, sus-
pension system or front end structure.
This could affect proper operation of
the supplemental front air bag system.
cTampering with the supplemental front
air bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel and the
instrument panel assembly by placing
material over the steering wheel pad
and above the instrument panel or by
installing additional trim material
around the air bag system.

cWork on and around the supplemental
front air bag system should be done by
a NISSAN dealer. Installation of electri-
cal equipment should also be done by a
NISSAN dealer. The Supplemental Re-
straint System (SRS) wiring should not
be modified or disconnected. Unautho-
rized electrical test equipment and
probing devices should not be used on
the air bag system.
cA cracked windshield should be re-
placed immediately by a qualified re-
pair facility. A cracked windshield could
affect inflation of the supplemental air
bag system.
cThe SRS wiring harness connectors are
yellow and orange for easy
identification.
When selling your vehicle, we request that you
inform the buyer about the supplemental front air
bag system and guide the buyer to the appropri-
ate sections in this Owner’s Manual.Pre-tensioner seat belt system (for
front seats)
WARNING
cThe pre-tensioner seat belt cannot be
reused after activation. It must be re-
placed together with the retractor and
buckle as a unit.
cIf the vehicle becomes involved in a
frontal collision but the pre-tensioner is
not activated, be sure to have the pre-
tensioner system checked and, if nec-
essary, replaced by your NISSAN
dealer.
cNo unauthorized changes should be
made to any components or wiring of
the pre-tensioner seat belt system. This
is to prevent accidental activation of
the pre-tensioner seat belt or damage
to the pre-tensioner seat belt operation.
Tampering with the pre-tensioner seat
belt system may result in serious per-
sonal injury.cWork around and on the pre-tensioner
system should be done by a NISSAN
dealer. Installation of electrical equip-
ment should also be done by a NISSAN
dealer. Unauthorized electrical test
equipment and probing devices should
not be used on the pre-tensioner seat
belt system.
cIf you need to dispose of the pre-
tensioner or scrap the vehicle, contact a
NISSAN dealer. Correct pre-tensioner
disposal procedures are set forth in the
appropriate NISSAN Service Manual.
Incorrect disposal procedures could
cause personal injury.
The front seat pre-tensioner seat belt system
activates in conjunction with the supplemental air
bag systems. Working with the seat belt retrac-
tor, it helps tighten the seat belt when the vehicle
becomes involved in certain types of collisions,
helping to restrain front seat occupants.
The pre-tensioner is encased with the seat belt’s
retractor. These seat belts are used the same as
conventional seat belts.
When the pre-tensioner seat belt activates,
smoke is released and a loud noise may be heard.
This smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it may
