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.
When the Intelligent Key battery is almost dis-
charged, insert the Intelligent Key into the
Intelligent Key port to start the engine. Replace
the discharged battery with a new one as soon
as possible. For more details, see “PUSH-
BUTTON IGNITION SWITCH” in the “5. Starting
and driving” section.
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.
For models with a steering wheel lock mecha-
nism: 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) degrees, the battery of the Intelli-
gent Key may not function properly.

AND SETTINGS” in the “4. Monitor, climate,
audio, phone and voice recognition systems”
section.)
Initialize entry/exit function
If the battery cable is disconnected, or if the
fuse opens, the entry/exit function will not work
though this function was set on before. In such
a case, after connecting the battery or replacing
with a new fuse, open and close the driver’s
door more than two times after the ignition
switch is turned from the ON position to the
LOCK position. The entry/exit function will be
activated.
SEAT SYNCHRONIZATION FUNCTION
The seat synchronization function automatically
adjusts the positions of the steering wheel and
outside mirrors when the seat is adjusted using
the power seat switches.
However, the steering wheel and outside mir-
rors will not move if the seat is adjusted over
the maximum thresholds. The system considers
that the steering wheel and outside mirror
adjustments are not necessary because the
seat may not be adjusted for the driving posi-
tion. Note that the function is set to disabled as
the factory default setting.The seat synchronization function operates un-
der the following conditions:
●
The ignition switch is in the ON position.
● The selector lever is in the P (Park) position
(Automatic Transmission models) or the
parking brake is applied (Manual Transmis-
sion models).
● The seatback is raised (Coupe).
If the outside mirrors or the steering wheel
reaches its maximum adjustment, the function
is automatically disabled. Restart the function
by selecting a previously stored seat memory
position using the memory switches (1 or 2). An
Intelligent Key that was previously linked to the
stored seat memory can also be used to restart
the function.
If a seat position was not previously stored in
the seat memory, restart the function by adjust-
ing the steering wheel and outside mirrors
manually for your best driving position and then
drive the vehicle above 4 MPH (7 km/h).
Cancel or activate seat
synchronization function
For Automatic Transmission models:
The selector lever must be in the P (Park)
position with the ignition switch in the ACC
position.

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the instrument
panel allows the driver to turn the sonar system
on and off. To turn the sonar system on and off,
the ignition switch must be in the “ON” posi-
tion. The indicator light
1on the switch will
illuminate when the system is turned off. If the
indicator light flashes when the sonar system is
not turned off, it may indicate a malfunction in
the sonar system.
WARNING
If the engine is not running or is turned off while
driving, the power assist for the steering will
not work. Steering will be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.

WARNING
Always follow the instructions below. Failure to
do so could result in damage to the charging
system and cause personal injury.
1. If the booster battery is in another vehicle
A, position the two vehicles (AandB)
to bring their batteries into close proxim-
ity to each other.
Do not allow the two vehicles to touch.
2. Apply parking brake. Move the selector lever to the P (Park) position (Automatic
transmission models). Move the shift le-
ver to the N (Neutral) position (Manual
transmission models). Switch off all un-
necessary electrical systems (light,
heater, air conditioner, etc.).
3. Remove vent caps on the battery (if so equipped). Cover the battery with a firmly
wrung out moist cloth
Cto reduce explo-
sion hazard. 4. Connect jumper cables in the sequence as
illustrated (
1→2→3→4).
For models with a steering wheel lock
mechanism:
If the battery is disconnected or discharged,
the steering wheel will lock and cannot be
turned. Supply power using jumper cables
before pushing the ignition switch and dis-
engaging the steering lock.
CAUTION
●Always connect positive (+) to positive (+)
and negative () to body ground (as illus-
trated) — not to the battery.
● Make sure the jumper cables do not touch
moving parts in the engine compartment and
that clamps do not contact any other metal.
5. Start the engine of the booster vehicleA
and let it run for a few minutes.
6. Keep the engine speed of the booster vehicle
Aat about 2,000 rpm, and start
the engine of the vehicle being jump
started

3. If engine overheating is caused by climb-ing a long hill on a hot day, run the engine
at a fast idle (approximately 1,500 rpm)
until the temperature gauge indication
returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the radia-
tor before opening the hood. (If steam or
coolant is escaping, turn off the engine.)
Do not open the hood further until no
steam or coolant can be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the engine,
stand clear to prevent getting burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan is
running. The radiator hoses and radiator
should not leak water. If coolant is leak-
ing or the cooling fan does not run, stop
the engine.
WARNING
Be careful not to allow your hands, hair, jewelry
or clothing to come into contact with, or get
caught in, engine belts or the engine cooling
fan. The engine cooling fan can start at any
time.
7. After the engine cools down, check thecoolant level in the reservoir tank with the
engine running. Add coolant to the reser-
voir tank if necessary. Have your vehicle
repaired at the nearest INFINITI retailer.
