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 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 that the buttons are not op-
erated unintentionally when the unit is
stored for a flight.
The Intelligent Key system can operate all the
door locks using the remote control function
or touching 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 sys-
tem 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 Intelligent Key system transmits weakradio 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 broad-
casting station.
•When in possession of wireless equip-
ment, such as a cellular telephone, trans-
ceiver or a CB radio.
•When the Intelligent Key is in contact with
or covered by metallic materials.
•When any type of radio wave remote con-
trol 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 condi-
tions before using the Intelligent Key function
or use the mechanical key.
Although the life of the battery varies de-
pending on the operating conditions, the bat-
tery's life is approximately two years. If the
battery is discharged, replace it with a new
one.

INFINITI INTELLIGENT KEY SYSTEM
3-8Pre-driving checks and adjustments

When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 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 operat-
ing 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.

The hazard warning flasher switch1oper-
ates regardless of the ignition switch position
except when the battery is discharged.
The hazard warning flasher is used to warn
other drivers when you have to stop or park
under emergency conditions.
When the hazard warning flasher switch is
pushed, all turn signal lights will flash. To turn
off the hazard warning flasher, push the haz-
ard warning switch again.
WARNING
•If stopping for an emergency, be sure to
move the vehicle well off the road.
•Do not use the hazard warning flashers
while moving on the highway unless un-
usual circumstances force you to drive
so slowly that your vehicle might be-
come a hazard to other traffic.
•Turn signals do not work when the haz-
ard warning flasher lights are on.
Some jurisdictions may prohibit the use of
the hazard warning flasher switch while
driving.If you have a flat tire, follow the instructions
in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
WARNING
•If the low tire pressure warning light il-
luminates or a tire pressure-related
warning is displayed by the vehicle in-
formation display while driving, avoid
sudden steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop the
vehicle as soon as possible. Driving with
under-inflated tires may permanently
damage the tires and increase the likeli-
hood of tire failure. Serious vehicle dam-
age could occur and may lead to an acci-
dent and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the tire and loading informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a replacement tire as
soon as possible.

8. Window washer fluid reservoir (P. 8-8)
WARNING
The engine cooling system is filled at the
factory with a high-quality, year-round,
antifreeze coolant solution. The antifreeze
solution contains rust and corrosion inhibi-
tors, therefore additional cooling system
additives are not necessary.
•Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused by
high-pressure fluid escaping from the
radiator. For additional information on
precautions, refer to "If your vehicle
overheats"
•The engine coolant reservoir tank is
equipped with a pressure type cap. To
prevent engine damage, use only a
genuine INFINITI pressure cap.
CAUTION
•Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.NIC2833
