PRECAUTIONS ON
SUPPLEMENTAL RESTRAINT
SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the driver and passenger supplemental front air
bags, supplemental side air bags and preten-
sioner seat belts.
Supplemental front impact air bag system:
This system can help cushion the impact force to
the face and chest of the driver and front passen-
ger in certain frontal collisions.
Supplemental side-impact air bag system
(if so equipped):This system can help cushion
the impact force to the chest area of the driver
and front passenger in certain side impact colli-
sions. The supplemental side air bag is designed
to inflate on the side where the vehicle is im-
pacted.
These supplemental restraint systems are de-
signed tosupplementthe crash protection pro-
vided by the driver and front passenger seat belts
and arenot 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, instrument paneland front door finishers. (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.

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.
cRight after inflation, several front air
bag system components will be hot. Do
not touch them; you may severely 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 around and on 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.

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.
Supplemental side air bag system (if
so equipped)
The supplemental side air bags are located in the
outside of the seatback of the front seats. The
supplemental side air bag (on the driver or front
passenger seat) is designed to inflate in higher
severity side collisions, although it may inflate if
the forces in another type of collision are similar
to those of a higher severity side impact. It is
designed to inflate on the side where the vehicle
is impacted. It may not inflate in certain side
collisions. Vehicle damage (or lack of it) is not
always an indication of proper supplemental side
air bag operation.When the supplemental side air bag inflates, a
fairly loud noise may be heard, followed by re-
lease 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 side air bags, along with the use of
seat belts, help to cushion the impact force on
the chest of the front occupants. They can help
save lives and reduce serious injuries. However,
an inflating side air bag may cause abrasions or
other injuries. Side air bags do not provide re-
straint 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 supplemental side air
bag. The side air bag inflates quickly in order to
help protect the front occupants. Because of this,
the force of the side air bag inflating can increase
the risk of injury if the occupant is too close to, or
is against, the side air bag module during infla-
tion. The side air bag will deflate quickly after a
collision.
The supplemental side air bags operate
only when the ignition switch is in the ON
or START position.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel, moni-
tors the circuits of the supplemental front air
bags, pre-tensioner seat belt and supplemental
side air bag (if so equipped) systems. The circuits
monitored by the supplemental air bag warning
light are the diagnosis sensor unit, crash zone
sensor, supplemental air bag modules, pre-
tensioner seat belts and all related wiring.
When the ignition key is in the ON or START
position, the supplemental air bag warning lightilluminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag and pre-tensioner seat belt systems need
servicing:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.
cThe supplemental air bag warning light flashes
intermittently.
cThe supplemental air bag warning light does
not come on at all.
Under these conditions, the supplemental front
air bag, supplemental side air bag or pre-
tensioner seat belt systems may not operate
properly. It must be checked and repaired. Take
your vehicle to the nearest NISSAN dealer.
WARNING
If the supplemental air bag warning light
is on, it could mean that the supplemental
front air bag or supplemental side air bag
system will not operate in an accident.
Repair and replacement procedure
The supplemental front air bags, pre-tensioner
seat belts and supplemental side air bags (if soequipped) are designed to inflate on a one-time-
only basis. As a reminder, unless it is damaged,
the supplemental air bag warning light remains
illuminated after inflation has occurred. Repair
and replacement of these supplemental air bag
systems should be done only by a NISSAN
dealer.
When maintenance work is required on the ve-
hicle, the supplemental front air bags, supple-
mental side air bags (if so equipped) , pre-
tensioner seat belts and related parts should be
pointed out to the person performing the mainte-
nance. The ignition key should always be in the
LOCK position when working under the hood or
inside the vehicle.
WARNING
cOnce a supplemental front air bag or
supplemental side air bag has inflated,
the air bag module will not function
again and must be replaced. Addition-
ally, if any of the supplemental front air
bags inflate, the activated pre-
tensioner seat belts must also be re-
placed. The air bag module and pre-
tensioner seat belt system should be
replaced by a NISSAN dealer. The air
bag module and pre-tensioner seat belt
system cannot be repaired.

WARNING
cAlways route the shoulder belt over
your shoulder and across your chest.
Never run the belt behind your back,
under your arm or across your neck. The
belt should be away from your face and
neck, but not falling off your shoulder.
cPosition the lap belt as low and snug as
possible AROUND THE HIPS, NOT THE
WAIST. A lap belt worn too high could
increase the risk of internal injuries in
an accident.cBe sure the seat belt tongue is securely
fastened to the proper buckle.
cDo not wear the seat belt inside out or
twisted. Doing so may reduce its
effectiveness.
cDo not allow more than one person to
use the same seat belt.
cNever carry more people in the vehicle
than there are seat belts.
cIf the seat belt warning light glows con-
tinuously while the ignition is turned
ON with all doors closed and all seat
belts fastened, it may indicate a mal-
function in the system. Have the system
checked by a NISSAN dealer.
cOnce the pre-tensioner seat belt has
activated, it cannot be reused and must
be replaced together with the retractor.
See your NISSAN dealer.
cRemoval and installation of the pre-
tensioner seat belt system components
should be done by a NISSAN dealer.cAll seat belt assemblies, including re-
tractors and attaching hardware,
should be inspected after any collision
by a NISSAN dealer. NISSAN recom-
mends that all seat belt assemblies in
use during a collision be replaced un-
less the collision was minor and the
belts show no damage and continue to
operate properly. Seat belt assemblies
not in use during a collision should also
be inspected and replaced if either
damage or improper operation is noted.
cAll child restraints and attaching hard-
ware should be inspected after any col-
lision. Always follow the restraint
manufacturer’s inspection instructions
and replacement recommendations.
The child restraints should be replaced
if they are damaged.
CHILD SAFETY
Children need adults to help protect them.
They need to be properly restrained.
The proper restraint depends on the child’s size.
Generally, infants up to about 1 year and less
than 20 pounds (9 kg) should be placed in rear
facing child restraints. Front facing child re-
straints are available for children who outgrow
rear facing child restraints.

When the ignition key is in the ON position, the
light comes on when the parking brake is applied,
and also warns of a low brake fluid level. If the
light comes on while the engine is running with
the parking brake not applied, stop the vehicle
and perform the following:
1. Check the brake fluid level. Add brake fluid
as necessary. See “Brake fluid” in the “Main-
tenance and do-it-yourself” section of this
manual.
2. If the brake fluid level is correct, have the
brake system checked by a NISSAN dealer.
WARNING
cYour vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition key is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
cPressing the brake pedal with the en-
gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.cIf the brake fluid level is below the
MINIMUM or MIN mark on the brake
fluid reservoir, do not drive until the
brake system has been checked at a
NISSAN dealer.
Charge warning light
If this light comes on while the engine is running,
it may indicate the charging system is not func-
tioning properly. Turn the engine off and check
the generator belt. If the belt is loose, broken,
missing, or if the light remains on, see a NISSAN
dealer immediately.
CAUTION
Do not continue driving if the generator
belt is loose, broken or missing.
