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 communicating
with the vehicle as it receives radio waves. The
Intelligent Key system transmits weak radio
waves. Environmental conditions may interfere
with the operation of the Intelligent Key system
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 sta-
tion.
● When in possession of wireless equipment,
such as a cellular telephone, transceiver,
and 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 com-
puter. ●
When the vehicle is parked near a parking
meter.
In such cases, correct the operating conditions
before using the Intelligent Key function or use
the mechanical key.
Although the life of the battery varies depend-
ing on the operating conditions, the battery’s
life is approximately 2 years. If the battery is
discharged, replace it with a new one.
When the Intelligent Key battery is almost dis-
charged, insert the Intelligent Key into the
Intelligent Key port to start the engine. Replace
the discharged battery with a new one as soon
as possible. For more details, see “PUSH-
BUTTON IGNITION SWITCH” in the “5. Starting
and driving” section.
Since the Intelligent Key is continuously receiv-
ing radio waves, if the key is left near equip-
ment which transmits strong radio waves, such
as signals from a TV and personal computer, the
battery life may become shorter.
For information regarding replacement of a bat-
tery, see “INTELLIGENT KEY BATTERY REPLACE-
MENT” in the “8. Maintenance and do-it-
yourself” section.
For models with a steering wheel lock mecha-
nism: Because the steering wheel is locked electri-
cally, unlocking the steering wheel with the
ignition switch in the LOCK position is impos-
sible when the vehicle battery is completely
discharged. Pay special attention that the ve-
hicle battery is not completely discharged.
As many as 4 Intelligent Keys can be registered
and used with one vehicle. For information
about the purchase and use of additional Intel-
ligent Keys, contact an INFINITI retailer.
CAUTION
●
Do not allow the Intelligent Key, which con-
tains electrical components, to come into
contact with water or salt water. This could
affect the system function.
● Do not drop the Intelligent Key.
● Do not strike the Intelligent Key sharply
against another object.
● Do not change or modify the Intelligent Key.
● Wetting may damage the Intelligent Key. If
the Intelligent Key gets wet, immediately
wipe until it is completely dry.
● If the outside temperature is below 14°F
(10°C) degrees, the battery of the Intelli-
gent Key may not function properly.
Pre-driving checks and adjustments3-7

NOTE:
The Intelligent Key port does not charge the In-
telligent Key battery. If you see the low battery
indicator in the dot matrix liquid crystal display,
replace the battery as soon as possible. (See
“INTELLIGENT KEY BATTERY REPLACEMENT” in
the “8. Maintenance and do-it-yourself” sec-
tion.)
CAUTION
●Never place anything except the Intelligent
Key in the Intelligent Key port. Doing so may
cause damage to the equipment.
● Make sure the Intelligent Key is in the cor-
rect direction when inserting it to the Intelli-
gent Key port. The engine may not start if it is
in the incorrect direction.
● Remove the Intelligent Key from the Intelli-
gent Key port after the ignition switch is
pushed to the OFF position. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid and window 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 appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is pushed to the ON
position. (See “WARNING/INDICATOR LIGHTS
AND AUDIBLE REMINDERS” in the “2. Instru-
ments and controls” section.)

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
●Park the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. For
manual transmission models, move the shift
lever to N (Neutral). For automatic transmis-
sion models, move the selector lever to P
(Park).
● Be sure the ignition switch is in the OFF or
LOCK position when performing any parts
replacement or repairs.
● Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
● Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position. ●
If you must work with the engine running,
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 jewelry, such as
rings, watches, etc. before working on your
vehicle.
● Always wear eye protection whenever you
work on your vehicle.
● If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
● Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
● Keep smoking materials, flame and sparks
away from fuel tank and the battery. ●
Your vehicle is equipped with an automatic
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 discon-
nect the negative battery cable before work-
ing near the fan.
● The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine 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 direct contact with used engine oil and
coolant. Improperly disposed engine oil,
coolant, and/or other vehicle fluids can dam-
age the environment. Always conform to lo-
cal regulations for disposal of vehicle fluid.
