device must accept any interference re-
ceived including interference that may
cause undesired operation of the device.
WARNING
IMake sure the hood is completely
closed and latched before driving.
Failure to do so could cause the
hood to fly open and result in an
accident.
IIf you see steam or smoke coming
from the engine compartment, to
avoid injury do not open the hood.
1. Pull the hood lock release handle located
below the driver side instrument panel;
the hood then springs up slightly.2. Lift the lever at the front of the hood with
your fingertips and raise the hood.
3. Insert the support rod into the slot in the
front edge of the hood.
4. When closing the hood, reset the support
rod to its original position, lower the hood
to approximately 12 inches above the
latch and release it. This allows proper
engagement of the hood latch.

Open the glove box by pulling the handle.
WARNING
Keep glove box lid closed while driving
to prevent injury in an accident or a
sudden stop.The fuel filler cap is a screw-on ratcheting
type. Tighten the cap clockwise until ratch-
eting clicks are heard.
WARNING
IGasoline is extremely flammable and
highly explosive under certain con-
ditions. You could be burned or se-
riously injured if it is misused or
mishandled. Always stop the engine
and do not smoke or allow open
flames or sparks near the vehicle
when refueling.IFuel may be under pressure. Turn
the cap one-half turn and wait for
any ``hissing'' sound to stop to pre-
vent fuel from spraying out and
causing possible personal injury.
Then remove the cap.
IDo not attempt to top off the fuel
tank after the fuel pump nozzle shuts
off automatically. Continued refuel-
ing may cause fuel overflow, result-
ing in fuel spray and possibly fire.
IUse only a genuine NISSAN fuel filler
cap as a replacement. It has a built-in
safety valve needed for proper op-
eration of the fuel system and emis-
sion control system. An incorrect
cap can result in a serious malfunc-
tion and possible injury.
INever pour fuel into the throttle body
to attempt to start your vehicle.
CAUTION
IIf fuel is spilled on the vehicle body,
flush it away with water to avoid
paint damage.

AM-FM RADIO WITH CASSETTE
PLAYER
RADIO OPERATION
To turn the radio on, turn the ignition key to
the ACC or ON position. If you listen to the
radio with the engine not running, turn the
key to the ACC position.
Radio reception is affected by station signal
strength, distance from radio transmitter,
buildings, bridges, mountains and other ex-
ternal influences. Intermittent changes in
reception quality normally are caused by
these external influences.
Using a cellular phone in or near the vehicle
may influence radio reception quality.
ON×OFF/VOL control knob
Turn the ignition key to the ACC or ON
position, then push the ON×OFF/VOL con-
trol knob. If you listen to the radio with the
engine not running, turn the key to the ACC
position. The mode (radio or cassette)
which was playing immediately before the
system was turned off resumes playing.
When no cassette is loaded, the radio
comes on. Pushing the ON×OFF/VOL con-
trol knob again turns the system off.

The antenna cannot be shortened, but it can
be removed. When you need to remove the
antenna, turn the antenna rod counterclock-
wise.
To install the antenna rod, turn the antenna
clockwise. Tighten the antenna rod to speci-
fication using a suitable tool such as a
open-end wrench. The antenna rod tighten-
ing specification is 3.4 - 3.6 N×m(30-32
in-lb). Do not use pliers to tighten the an-
tenna as they can leave marks on the
antenna surface. The antenna rod can not
be hand tightened to the proper specifica-
tion.
CAUTION
Always properly tighten the antenna
rod during installation or the antenna
rod may break during vehicle opera-
tion.
Microphone installed model
If equipped with a genuine NISSAN cellular
phone, your NISSAN features a non-
directional
microphone in the steering column cover, so
it is not necessary to look at or speak
directly into the microphone when calling. To
do so could detract from the driving opera-
tion and cause an accident. See the manual
for car phone operation.
Pre-wired and antenna for phone
installed model
Some models are pre-wired to accept the
genuine NISSAN cellular phone. In addition,
the same model has the phone antenna
built into the rear glass window.
When installing a CB, ham radio or car
phone in your NISSAN, be sure to observe
the following cautions, otherwise the new
equipment may adversely affect the MFI
(Multiport Fuel Injection) system and other
electronic parts.CAUTION
IKeep the antenna as far as possible
away from the Engine Control Mod-
ule.
IAlso keep the antenna wire more
than 8 inches (20 cm) away from the
MFI harness. Do not route the an-
tenna wire next to any harness.
IAdjust the antenna standing-wave
ratio as recommended by the manu-
facturer.

WARNING
Do 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.
EXHAUST GAS (carbon monoxide)
WARNING
Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is a dan-
gerous gas, and can cause uncon-
sciousness or death.
IIf you suspect that exhaust fumes
are entering the vehicle, drive with
all windows fully open, and have the
vehicle inspected immediately.
IDo not run the engine in closed
spaces such as a garage.IDo not park the vehicle with the
engine running for any extended
length of time.
I
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.)
IThe 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 control
device installed in the exhaust system. Ex-
haust gases in the converter are burned at
high temperatures to help reduce pollutants.
WARNING
IThe exhaust gas and the exhaust
system are very hot. Keep people or
flammable materials away from the
exhaust pipe.
IDo not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
CAUTION
IDo not use leaded gasoline. Depos-
its from leaded gasoline will seri-
ously reduce the three-way cata-
lyst's ability to help reduce exhaust
pollutants.
IKeep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause over-
rich fuel flow into the converter,
causing it to overheat.
