a fire. Care should be taken to not inhale it,
as it may cause irritation and choking.
Those with a history of a breathing condition
should get fresh air promptly.
The supplemental front air bags, along with
the use of seat belts, help to cushion the
impact force on the face and chest of the
occupant. They can help save lives and
reduce serious injuries. However, an inflat-
ing 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
instrument panel. The supplemental front air
bags inflate quickly in order to help protect
the front occupants. Because of this, the
force of the front air bag inflating can in-
crease 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 warn-
ing light illuminates. The supplemental
air bag warning light will turn off after
about 7 seconds if the system is opera-
tional.
WARNING
c
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 supple-
mental front air bag inflates.
cRight after inflation, several front air
bag system components will be hot.
Do not touch them; you may se-
verely burn yourself.
c
No unauthorized changes should be
made to any components or wiring of
the supplemental front air bag sys-
tem. This is to prevent accidental in-
flation of the front air bags or damage
to the front air bag system.cDo not make unauthorized changes to
your vehicle's electrical system, sus-
pension system or front end struc-
ture. This could affect proper opera-
tion of the supplemental front air bag
system.
cTampering with the supplemental
front air bag system may result in
serious personal injury. For ex-
ample, do not change the steering
wheel and instrument panel assem-
bly by placing material over the
steering wheel pad and above the
dashboard or by installing additional
trim material around the front air bag
system.
cWork around and on the supplemen-
tal front air bag system should be
done by an authorized NISSAN
dealer. Installation of electrical
equipment should also be done by
an authorized NISSAN dealer. The
SRS wiring should not be modified
or disconnected. Unauthorized elec-
trical test equipment and probing
devices should not be used on the
supplemental front air bag system.

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 de-
signed 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 ofproper supplemental side air bag operation.
When the supplemental side air bag in-
flates, 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 to not inhale it, as it
may cause irritation and choking. 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 seri-
ous injuries. However, an inflating side air
bag may cause abrasions or other injuries.
Side air bags 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 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 inflation. 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.
After turning the ignition key to the ON
position, the supplemental air bag warn-
ing light illuminates. The supplemental
air bag warning light will turn off after
about 7 seconds if the system is opera-
tional.
WARNING
cDo 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 ob-
jects may become dangerous pro-
jectiles and cause injury if the
supplemental side air bag inflates.
cRight after inflation, several supple-
mental side air bag system compo-
nents 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 side air bag sys-
tem. This is to prevent accidentalinflation of the side air bag or dam-
age to the side air bag system.
cDo 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 system.
cTampering with the supplemental
side air bag system may result in
serious personal injury. For ex-
ample, do not change the front seat
assembly by placing material near
the seatback of the front seat or by
installing additional trim material,
such as seat covers, around the side
air bag system.
cWork around and on the supplemen-
tal side air bag system should be
done by an authorized NISSAN
dealer. Installation of electrical
equipment should also be done by
an authorized NISSAN dealer. The
SRS wiring harnesses* should not
be modified or disconnected. Unau-
thorized electrical test equipment
and probing devices should not be
used on the side air bag system.* The SRS wiring harness connectors
are yellow for easy identification.
When selling your vehicle, we request that
you inform the buyer about the supplemen-
tal side air bag system and guide the buyer
to the appropriate 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
replaced together with the retractor
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 necessary, replaced
by your NISSAN dealer.

cNo unauthorized changes should be
made to any components or wiring
of the pre-tensioner seat belt sys-
tem. 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 personal in-
jury.
cWork around and on the pre-
tensioner system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN 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, con-
tact an authorized NISSAN dealer.
Correct pre-tensioner disposal pro-
cedures are set forth in the appropri-
ate NISSAN Service Manual. Incor-
rect disposal procedures could
cause personal injury.The front seat pre-tensioner seat belt sys-
tem activates in conjunction with the supple-
mental front air bag. Working with the seat
belt retractor, it helps tighten the seat belt
the instant the vehicle becomes involved in
certain types of collisions, thereby restrain-
ing 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 to
not inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
If any abnormality occurs in the pre-
tensioner system, the supplemental air bag
warning light
will flash intermittently
after the ignition key is turned to the ON or
START position. In this case, the pre-
tensioner seat belt will not function properly.
When selling your vehicle, we request that
you inform the buyer about the pre-
tensioner seat belt system and guide thebuyer to the appropriate sections in this
Owner's Manual.

WARNING
cDo not leave children, impaired
adults, or pets alone in your vehicle.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on
hot, sunny days, temperatures in a
closed vehicle could quickly become
high enough to cause severe or pos-
sibly fatal injuries to people or ani-
mals.
cClosely supervise children when
they are around cars to prevent them
from playing and becoming locked
in the trunk where they could be
seriously injured. Keep the car
locked, with the trunk closed, when
not in use, and prevent children's
access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
cDo not breathe exhaust gases; they
contain colorless and odorless car-bon monoxide. Carbon monoxide is
dangerous. It can cause uncon-
sciousness or death.
cIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows fully open, and have the
vehicle inspected immediately.
cDo not run the engine in closed
spaces such as a garage.
cDo not park the vehicle with the
engine running for any extended
length of time.
cKeep the trunk lid closed while driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive with the
trunk lid open, follow these precau-
tions.
1. Open all the windows.
2. Set the
air recirculation but-
ton (if so equipped) to off and the
fan control dial to 4 (high) to cir-
culate the air.cIf electrical wiring or other cable
connections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle.
cThe exhaust system and body
should be inspected by a qualified
mechanic whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.
d.
You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
PRECAUTIONS WHEN
STARTING AND DRIVING
5-2Starting and driving
ZX

cDo not modify the vehicle exhaust
system, brake system, etc. to install
a trailer hitch.
cTo reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
cAfter the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
cRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver's side rear door
pillar).
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. Safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. Be sure to leave enough slack in the
chains to permit turning corners.
Trailer lights
Trailer lights should comply with federal
and/ or local regulations. When wiring the
vehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloadedtrailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose- down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shift while driving.
cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
