If this indicator appears, replace the
battery with a new one. (See “Intelligent
Key battery replacement” (P.8-27).)
8. Parking brake release warning
This warning appears when the vehicle
speed is above 4 MPH (7 km/h) and the

WARNING
.Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
for the possible influences before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that the radio waves
may affect aircraft navigation and com-
munication systems. Do not operate the
Intelligent Key while on an airplane.
Make sure the buttons are not operated
unintentionally when the unit is stored
during a flight.
The Intelligent Key system can operate all
doors and the lift gate using the remote
controller 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 system
operation.
Be sure to read the following before using
the Intelligent Key system.
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 system trans-
mits 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 station.
. When in possession of wireless equip-
ment, 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 perso- nal computer.
. When the vehicle is parked near a
parking meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key
function or use the mechanical key.
Although the life of the battery varies
depending 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
discharged, 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” (P.5-10).
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment 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
battery, see “Intelligent Key battery repla-
cement” (P.8-27).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
Pre-driving checks and adjustments3-7

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
almost discharged, the guide light
*Aof
the Intelligent Key port blinks and the
indicator appears on the dot matrix liquid
crystal display. (See “Dot matrix liquid
crystal display” (P.2-21).)
In this case, inserting the Intelligent Key

*1allows you to start the
engine. Make sure that the key ring side
faces backward as illustrated. Insert the
Intelligent Key in the port until it is latched
and secured. To remove the Intelligent Key from the port,
push the ignition switch to the OFF position
and pull the Intelligent Key out of the port.
NOTE:
The Intelligent Key port does not charge
the Intelligent 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” (P.8-27).)
CAUTION
.Never place anything except the Intelli-
gent Key in the Intelligent Key port.
Doing so may cause damage to the
equipment.
. Make sure the Intelligent Key is in the
correct direction when inserting it to the
Intelligent Key port. The engine may not
start if it is in the incorrect direction.
. Remove the Intelligent Key from the
Intelligent 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,
coolant, 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 appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. 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. (See “Warning/indica-
tor lights and audible reminders” (P.2-
12).)

if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior” (P.7-2).
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. 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
following are general precautions which
should be closely observed.
WARNING
.
Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. 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 ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected 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
supported 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 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 working near the
fan.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced by
an INFINITI retailer because the fuel lines
