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 may cause injury if the

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.
cWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN dealer. The yellow SRS wiring
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the supple-
mental air bag system.
cThe SRS wiring harnesses are cov-
ered with yellow insulation either
just before the harness connectors
or on the complete harness for easy
identification.

WARNING
cDo 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 possibly
fatal injuries to people or animals.
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
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous.It can cause unconsciousness
or death.
c
If you suspect that exhaust fumes areentering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
cDo not run the engine in a closed
space such as a garage.
cDo not park the vehicle with the en-
gine 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 in this
manner for some reason, take the
following steps:
1. Open all the windows.
2. Set the air recirculation button (if
so equipped) off and the fan con-
trol dial to four (high) to circulate
the air.
3.
Be sure the rear seats are secured
and latched in the upright position.
cIf electrical wiring or other cable con-
nections 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.
WARNING
c
The exhaust gas and the exhaust sys-
tem are very hot. Keep people or flam-
mable materials away from the ex-
haust pipe.
cDo not stop or park the vehicle over
flammable materials such as dry
PRECAUTIONS WHEN
STARTING AND DRIVING
5-2Starting and driving
ZX

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 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 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.
c
Always 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 an automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift selector lever into the P position.
If you move the shift selector lever to the P
position before blocking the wheels andapplying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
cIf the engine temperature coolant rises
to an extremely high temperature when
the air conditioning system is on, turn off
the air conditioner. Coolant heat can be
additionally vented by opening the win-
dows, switching the fan control to high
and setting the temperature control to
the HOT position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
