Instruments and controls2-27

WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use.
∙ The Intelligent Key transmits radio waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraf t navigation and com-
munication systems. Do not operate
the Intelligent Key while on an air-
plane. Make sure the buttons are not
operated unintentionally when the
unit is stored for a flight.
The Intelligent Key can operate all the door
locks using the remote control function or
pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key
operation.
Be sure to read the following before using
the Intelligent Key.
CAUTION
∙ Be sure to carry the Intelligent Key with you when operating the vehicle.
∙ Never leave the Intelligent Key in the vehicle when you leave the vehicle.
The Intelligent Key is always communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key transmits weak
radio waves. Environmental conditions
may interfere with the operation of the In-
telligent Key under the following operating
conditions: ∙ When operating near a location where strong radio waves are transmitted,
such as a TV tower, power station and
broadcasting station.
∙ When in possession of wireless equip- ment, such as a cellular telephone,
transceiver or a CB radio.
∙ When the Intelligent Key is in contact with or covered by metallic materials.
∙ When any type of radio wave remote control is used nearby.
∙ When the Intelligent Key is placed near an electric appliance such as a personal
computer. ∙ When the vehicle is parked near a park-
ing meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the
battery’s life is approximately two years. If
the battery is discharged, replace it with a
new one.
When the Intelligent Key battery is low, an
indicator illuminates in the vehicle informa-
tion display. For additional information, re-
fer to “Vehicle information display” in the
“Instruments and controls” section of this
manual.
Since the Intelligent Key is continuously re-
ceiving radio waves, if the key is lef t near
equipment which transmits strong radio
waves, such as signals from a TV and per-
sonal computer, the battery life may be-
come shorter.
For additional information, refer to “Battery
replacement” in the “Do-it-yourself ” section
of this manual.

Intelligent Key battery discharge in-
dicator appears in the vehicle infor-
mation display even when the Intelli-
gent Key is inside the vehicle. This is
not a malfunction. To turn off the In-
telligent Key battery discharge indi-
cator, touch the ignition switch with

∙ If the Intelligent Key battery dis-
charge indicator appears, replace the
battery as soon as possible. For addi-
tional information, refer to “Battery
replacement” in the “Do-it-yourself ”
section of this manual.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key.
If the engine fails to start using a registered
key (for example, when interference is
caused by another registered key, an auto-
mated toll road device or automatic pay-
ment device on the key ring), restart the
engine using the following procedure:
1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the in-
terference) separate from the regis-
tered key.
If the no start condition re-occurs, NISSAN
recommends placing the registered key on
a separate key ring to avoid interference
from other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, and windshield-
washer fluid as frequently as possible,
or at least whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust headrests/head restraints.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is pushed to
the ON position. For additional informa-
tion, refer to “Warning lights, indicator
lights and audible reminders” in the “In-
struments and controls” section of this
manual.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
∙ Be sure the ignition key is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine run- ning, keep your hands, clothing, hair
and tools away from moving fans,
belts and any other moving parts.
∙ It is advisable to secure or remove any loose clothing and remove any jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your 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 work-
ing near the fan.
∙ If you must run the engine in an en- closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
∙ Never get under the vehicle while it is supported only by a jack. If it is neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced. It
is recommended that you visit a
NISSAN dealer for this service because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
∙ Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down. ∙
Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
