gauge reaches the empty (0) position.

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, see “Intelligent Key battery
discharge” (P.5-13) to start the engine.
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.8-24).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.
CAUTION
. Do not allow the Intelligent Key, which
contains 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, immedi-
ately wipe until it is completely dry.
. Do not place the Intelligent Key for an
extended period in an area where
temperatures exceed 1408F (608C).
. If the outside temperature is below 148F
(−108C), the battery of the Intelligent
Key may not function properly.
. Do not attach the Intelligent Key with a
key holder that contains a magnet.
. Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment
and personal computers.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions
interfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the shift lever to the P (Park)position.
2. Firmly apply the foot brake.

NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears in the vehicle informa-
tion display even if the Intelligent Key
is inside the vehicle. This is not a
malfunction. To turn off the Intelligent
Key battery discharge indicator, touch
the ignition switch with the Intelligent
Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Intelligent
Key battery replacement” (P.8-24).).
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.

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.
. The fuel filter or fuel lines should be
serviced by an INFINITI retailer because
