WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use.
● The Intelligent Key transmits radio
waves when the buttons are pressed.
The FAA advises the radio waves may
affect aircraft navigation and communi-
cation systems. Do not operate the In-
telligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally when the unit is stored for a
flight.
The Intelligent Key system can operate all the
door locks 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 af-
fect 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 communicating with
the vehicle as it receives radio waves. The Intel-
ligent 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
station.
● 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 depending
on the operating conditions, the battery’s life is
approximately 2 years. If the battery is dis-
charged, replace it with a new one.
When the Intelligent Key battery is low, an indi-
cator illuminates in the Vehicle Information Dis-
play. See “Vehicle Information Display” in the
“Instrument Control” section.
Since the Intelligent Key is continuously receiving
radio waves, if the key is left near equipment
which transmits strong radio waves, such as sig-
nals from a TV and personal computer, the bat-
tery life may become shorter.
For information regarding replacement of a bat-
tery, see “Battery replacement” in the “Mainte-
nance and do-it-yourself” section.
Because the steering wheel is locked electrically,
unlocking the steering wheel with the ignition
switch in the LOCK position is impossible when
the vehicle battery is completely discharged. Un-
locking the steering wheel is impossible even if
the Intelligent Key is inserted into the ignition

OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the specified
operating range from the request switch
1.
When the Intelligent Key battery is discharged or
strong radio waves are present near the operat-
ing location, the Intelligent Key operating range
becomes narrower, and the Intelligent Key may
not function properly.
The operating range is within 31.50 in (80 cm)
from each request switch
1. If the Intelligent Key is too close to the door glass,
handle or rear bumper, the request switches may
not function.
When the Intelligent Key is within the operating
range, it is possible for anyone, even someone
who does not carry the Intelligent Key, to push the
request switch to lock/unlock the doors.
DOOR LOCKS/UNLOCKS
PRECAUTION
●
Do not push the door handle request switch
with the Intelligent Key held in your hand as
illustrated. The close distance to the door
handle will cause the Intelligent Key system
to have difficulty recognizing that the Intelli-
gent Key is outside the vehicle.
● After locking with the door handle request
switch, verify the doors are securely locked
by testing them.

WARNING
●The driver must not attempt to operate
or view the Mobile Entertainment Sys-
tem while the vehicle is in motion so
that full attention may be given to ve-
hicle operation.
● Do not attempt to modify the system to
display a movie on the front screen
while the vehicle is being driven. Doing
so may distract the driver and may
cause a collision and serious personal
injury or death.
CAUTION
● The glass screen on the liquid crystal
display may break if hit with a hard or
sharp object. If the glass breaks, do not
touch the liquid crystalline material,
which contains a small amount of mer-
cury. In case of contact with skin, wash
immediately with soap and water.
● Use a damp, soft cloth when cleaning
the Mobile Entertainment System com-
ponents. Do not use solvents or clean-
ing solutions. Do not attempt to use the system in extreme
temperature conditions [below -4°F (-20°C) or
above 158°F (70°C)].
To avoid discharging the vehicle battery, do not
operate the system more than 15 minutes without
starting the engine.

Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is turned to the ON posi-
tion. This allows the vehicle to be moved if the
battery is discharged.
To push the shift lock release, complete the fol-
lowing procedure:1. Place the ignition switch in the LOCK posi-
tion.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Insert a small screwdriver in the shift lock release slot and push down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Turn the ignition switch to the ON position to unlock the steering wheel. Now the vehicle
may be moved to the desired location.
If the shift selector cannot be moved out of P
(Park) , have an INFINITI dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, place the ignition
switch in the OFF position and wait for 3
seconds. Then turn the ignition switch back
to the ON position. The vehicle should re-
turn to its normal operating condition. If it
does not return to its normal operating
condition, have an INFINITI dealer check
the transmission and repair it if necessary.
