INFINITI INTELLIGENT KEY
BATTERY DISCHARGE
If the battery of the Intelligent Key is dis-
charged, or environmental conditions inter-
fere with the Intelligent Key operation, start
the engine according to the following proce-
dure:
1. Press the park button to shift to the P(Park) position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelli- gent Key as illustrated. (A chime will
sound.) 4. Push the ignition switch while depressing
the brake pedal within 10 seconds after
the chime sounds. The engine will start.
After step 3 is performed, when the ignition
switch is pushed without depressing the
brake pedal, the ignition switch position will
change to ON.
NOTE:
• When the ignition switch is pushed to the ON position or the engine is started by the
above procedures, the “Key Battery Low”
warning appears (on the vehicle informa-
tion display) even if the Intelligent Key is
inside the vehicle. This is not a malfunc-
tion. To turn off the warning, touch the
ignition switch with the Intelligent Key
again.
• If the “Key Battery Low” warning appears, replace the battery as soon as possible.
For additional information, see “Battery
replacement” (P. 8-24).
INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key. If the engine does not start using the regis-
tered Intelligent Key, it may be due to inter-
ference caused by:
• Another Intelligent Key.
• Automated toll road device.
• Automated payment device.
• Other devices that transmit similar signals.
Start the engine using the following
procedure:
1. Remove any items that may be causing
the interference away from the Intelligent
Key.
2. Start the engine again.
If this procedure allows the engine to start,
INFINITI recommends placing the registered
Intelligent Key separate from other devices to
avoid interference.

When performing any inspection or maintenance
work on your vehicle, always take care to pre-
vent serious accidental injury to yourself or dam-
age 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 mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch 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 jewelry,
such as rings, watches, etc. before work-
ing 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 switch 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.
• 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 the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel filter or fuel lines.
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 flu-
ids can damage the environment. Always
conform to local regulations for disposal
of vehicle fluid. •
Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-36).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.

follows:
1. Remove the mechanical key from the In- telligent Key.
2. Insert a small flathead screwdriver
OAinto
the slit
OBof the corner and twist it to

3. Replace the battery with a new one.Recommended battery: CR2032 or
equivalent.
• Do not touch the internal circuit and electric terminals as doing so 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 bot- tom of the lower part.
4. Close the lid securely as illustrated with
OCandOD.
5. Operate the buttons to check the operation.
If you need assistance with replacement, it is
recommended that you visit an INFINITI re-
tailer for this service.
