tion, cautions and warnings in this manual
still apply and must be followed.
The supplemental air bag system is de-
signed 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 frontal collisions.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental air bag
system operation.
When the supplemental 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, but
care should be taken not to intentionally
inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
The supplemental air bags, along with the
use of the seat belts, helps to cushion the
impact force on the face and chest of the
occupant. It can help save lives and reduce
serious injuries. However, an inflating sup-
plemental air bag may cause facial abrasions
or other injuries. Supplemental air bags do
not provide restraint to the lower body.
Seat belts should be correctly worn and thedriver and passenger seated upright as far
as practical away from the steering wheel or
instrument panel. Since the supplemental air
bags inflate quickly in order to help protect
the front occupants, the force of the supple-
mental air bags inflating can increase the
risk of injury if the occupant is too close to or
against the supplemental air bag module
during inflation.
The supplemental air bags deflate quickly
after a collision.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
WARNING
ODo not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or on the instru-
ment panel. Such objects may be-
come dangerous projectiles, and
cause injury if the supplemental air
bag inflates.
ORight after inflation, several supple-
mental air bag system componentswill be hot. Do not touch them; you-
may severely burn yourself.
O
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 supplemental air bag or damage
to the supplemental air bag system.
ODo 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 air bag system.
OTampering with the supplemental 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 supplemental air
bag system.
OWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer.

Installation of electrical equipment
shouldalso be done by an authorized
NISSAN dealer. The yellow Supple-
mental Restraint System (SRS) wir-
ing should not be modified or dis-
connected. Unauthorized electrical
test equipment and probing devices
should not be used on the supple-
mental air bag system.
OThe SRS wiring harnesses (except
the pre-tensioner seat belt system)
are covered with yellow insulation
either just before the harness con-
nectors or over the complete har-
ness for easy identification.
When selling your vehicle, we request that
you inform the buyer about the supplemental
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
OThe pre-tensioner seat belt cannot
be reused after activation. It must bereplaced together with the retractor
and buckle as a unit.
OIf 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.
ONo 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.
OWork around and on the pre-
tensioner system should be done by
an authorized NISSAN dealer.
Installation of electrical equipment
should also be done by an autho-
rized NISSAN dealer. Unauthorized
electrical test equipment and prob-
ing devices should not be used onthe pre-tensioner seat belt system.
OIf 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 conjuction with the supple-
mental 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.
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. The smoke is not harmful, but care
should be taken not to intentionally inhale it
as it may cause irritation and choking.
If any abnormality occurs in the pre-
tensioner system, the supplemental air bag
warning light
will flash intermit-

WARNING
ODo not leave children, unreliable
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.
OProperly secure all cargo to help
prevent it from sliding or shifting. Do
not place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
ODo not breathe exhaust gases; they
contain colorless and odorless car-
bon monoxide. Carbon monoxide is
a dangerous. It can cause uncon-
sciousness or death.OIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows fully open, and have the
vehicle inspected immediately.
ODo not run the engine in closed
spaces such as a garage.
ODo not park the vehicle with the
engine running for any extended
length of time.
OKeep the back door and rear win-
dows closed while driving, other-
wise exhaust gases could be drawn
into the passenger compartment. If
you must drive with the back door or
rear windows open, follow these pre-
cautions:
1. Open all the windows.
2. Set the air recirculation switch
OFF and the fan control at 4 (high)
to circulate the air.
OIf electrical wiring or other cable
connections must pass to a trailer
through the seal on the back door or
the body, follow the manufacturer's
recommendation to prevent carbon
monoxide entry into the vehicle.O
If a special body, camper, or other
equipment is added for recreational
or other usage, follow the manufac-
turer's recommendation to prevent
carbon monoxide entry into the ve-
hicle. Do not occupy these areas
while the engine is running even if the
vehicle is parked. Some recreational
vehicle appliances such as stoves,
refrigerators, heaters, etc. may also
generate carbon monoxide.
OThe 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.
PRECAUTIONS WHEN
STARTING AND DRIVING

ZX

4) Connect the tow harness connector
(SAE J1239) to your trailer.
5) Confirm proper vehicle and trailer
stop/turn lamp operation.
6) When towing is completed, disconnect
the tow harness from the trailer and the
vehicle. Store the tow harness in the
glove box. Reinstall the connector cap to
the vehicle harness.
If you need further assistance in wiring
a trailer to your NISSAN, contact an autho-
rized NISSAN dealer.
Always confirm proper vehicle and
trailer stop/turn lamp operation every
time the trailer light circuits are con-
nected for use.
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
OBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer 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 possible causes of either condi-
tion.
OAlways secure items in the trailer to
prevent load shift while driving.
OBe certain your outside mirrors conform
to all federal, state or local regulations. 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 will be
somewhat different than under normal driv-
ing conditions.
OAlways secure items in the trailer to
prevent load shift while driving.
O
Avoid abrupt starts, acceleration or stops.
OAvoid sharp turns or lane changes.
OAlways drive your vehicle at a moderate
speed.
OAlways block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P (Park)
position. If you move the shift lever to the
P (Park) position before blocking the
wheels and applying the parking brake,
transmission damage could occur.
OWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, downshift
the transmission to a lower gear and
reduce speed to reduce chances of en-
gine overloading and/or overheating.
However, for long steep grades, do not
stay in 1st or 2nd gear when driving
above 35 MPH (56 km/h).
OIf the engine coolant rises to an ex-
tremely high temperature when the air
conditioning system is on, turn off the air
conditioner. Coolant heat can be addi-
