Instruments and controls2-23

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.
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.
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), the battery of the Intelligent Key
may not function properly.
● Do not place the Intelligent Key for an ex-
tended period in an area where tempera-
tures exceed 140°F (60°C).
● Do not attach the Intelligent Key with a key
holder that contains a magnet.
● Do not place the Intelligent Key near equip-
ment that produces a magnetic field, such as
a TV, audio equipment and personal
computers.

extremely close distances to the Dual
Head Restraint DVD System or when it
does not function at all. FCC Notice:
Changes or modifications not expressly ap-
proved by the party responsible for compliance
could void the user’s authority to operate the

BEFORE OPERATING DUAL HEAD
RESTRAINT DVD SYSTEM
Precautions
Start the engine when using the Dual Head
Restraint DVD System.
WARNING
The driver must not attempt to operate the Dual
Head Restraint DVD System or wear the head-
phones while the vehicle is in motion so that
full attention may be given to vehicle
operation.
CAUTION
●
Only operate the Dual Head Restraint DVD
System while the vehicle engine is running.
Operating the Dual Head Restraint DVD Sys-
tem for extended periods of time with the
engine OFF can discharge the vehicle
battery.
● Do not allow the system to get wet. Exces-
sive moisture such as spilled liquids may
cause the system to malfunction.
● While playing VIDEO-CD media, this DVD
player does not guarantee complete func-
tionality of all VIDEO-CD formats.

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. 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.
● On gasoline engine models, the fuel filter or
fuel lines should be serviced by an INFINITI
retailer 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 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.
This “8. Maintenance and do-it-yourself” sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9. Tech-
nical and consumer information” section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
your warranty coverage. If in doubt about any
servicing, we recommend that it be done by an
INFINITI retailer.

Maintenance and do-it-yourself8-5

NOTE:
If the extended storage switch malfunctions or if
the fuse is open, it is not necessary to replace
the switch. In this case, remove the extended
storage switch and replace it with a new fuse of
the same rating.
How to remove the extended storage switch:
1. To remove the extended storage switch,be sure the ignition switch is in the OFF or
LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
1found on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box
2.
Replace the battery as follows:
1. Release the lock knob at the back of the
Intelligent Key and remove the mechanical
key. 2. Insert a small screwdriver into the slit of
the corner and twist it to separate the
upper part from the lower part. Use a
cloth to protect the casing.
3. Replace the battery with a new one.
Recommended battery: CR2025 or equiva-
lent.
● Do not touch the internal circuit and
electric terminals as it could cause a
malfunction.
● Hold the battery by the edges. Holding
the battery across the contact points will
seriously deplete the storage capacity.
● Make sure that the + side faces the
bottom of the case.
