WARNING
.Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufacturer
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 the buttons are not operated
unintentionally when the unit is stored
during a flight.
The Intelligent Key system can operate all

operating environment and/or conditions
may affect 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 communicat-
ing with the vehicle as it receives radio
waves. The Intelligent Key system trans-
mits 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 equip-
ment, 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 perso- nal computer.
. 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
depending 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
discharged, 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” (P.5-10).
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.

selected position.
CAUTION
. Do not lean against a partially opened
lift gate. The lift gate may close un-
expectedly and may result in personal
injury.
. If the vehicle was driven by another
person, confirm the garage mode func-
tion before opening the lift gate in a
location with low clearance. The lift gate
can be damaged if the previous driver
changed or canceled the setting.
. If the switch is pressed two times
quickly (1 second or less) when opening
the lift gate from the fully closed
position, the system may not recognize
the second switch press. The lift gate
will continue to open. This is normal
operation and does not indicate a mal- function. However, this may result in
minor personal injury if someone is
behind the vehicle when the switch is
activated, or damage to the lift gate.
NOTE:
.
To avoid damaging the lift gate system,
do not manually force the lift gate to
open or close when the lift gate is
moving. When manually operating the
lift gate from the full close or full open
position, do not use excessive force.
Using excessive force may damage the
system.
. Do not install accessories such as bike
racks onto the lift gate. The additional
weight of these accessories may cause
the lift gate to operate slowly or to not
open completely. This is a normal
operation and does not indicate a
malfunction. The lift gate will operate
normally when the accessory is re-
moved.
. If the lift gate is opened when the
vehicle is parked on a steep slope, the
lift gate may not open to the expected
position. This is a normal operation
and does not indicate a malfunction. .
If the automatic lift gate is operated
continuously for approximately 180
seconds, the system automatically
turns off to prevent overheating. The
lift gate cannot be opened using the
switches. The system resets and opera-
tion returns to normal after approxi-
mately 180 seconds. This is a normal
operation and does not indicate a
malfunction.
. The lift gate may automatically reverse
direction if the lift gate is operating
and passengers enter/exit the vehicle.
This is a normal operation and does
not indicate a malfunction.
. The lift gate must be operated manually
if the battery is disconnected or
discharged.
. If the lift gate is not activated due to a
low voltage (less than approximately
11V), operate the lift gate with the
engine running.
Manual mode
If power operation is not available, the lift
gate can be operated manually. Power
operation may not be available if multiple
obstacles have been detected in a single
power cycle or if the battery voltage is low.

FUEL-FILLER CAP
WARNING
. Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop engine and do not smoke or
allow open flames or sparks near the
vehicle when refueling.
. Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
. Use only an original equipment type
fuel-filler cap as a replacement. It has a built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap can
result in a serious malfunction and
possible injury. It could also cause the
malfunction indicator light to come on.
. Never pour fuel into the throttle body to
attempt to start your vehicle.
. Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:—Always place the container on the
ground when filling.
—Do not use electronic devices when
filling.
—Keep the pump nozzle in contactwith the container while you are
filling it.
—Use only approved portable fuelcontainers for flammable liquid.
CAUTION
. If fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.
. Insert the cap straight into the fuel-filler
tube, then tighten until a single click is
heard. Failure to tighten the fuel-filler
cap properly may cause the
mal-
function indicator light (MIL) to illumi-
nate. If the
light illuminates
because the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the vehicle
inspected by an INFINITI retailer.
For additional information, see “Mal-
function Indicator Light (MIL)” (P.2-19).
. The LOOSE FUEL CAP warning will appear
if the fuel-filler cap is not properly
tightened. It may take a few driving
trips for the message to be displayed.
Failure to tighten the fuel-filler cap
properly after the LOOSE FUEL CAP
warning appears may cause the

Pre-driving checks and adjustments3-35

5-4Starting and driving
cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical systems can cause overrich fuel
flow into the three-way catalyst, causing
it to overheat. Do not keep driving if the
engine misfires, or if noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and it is the driver’
s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the mal-
function indicator is illuminated, the sys-
tem may not be able to detect or signal low
tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons,
including the installation of replacement or
alternate tires or wheels on the vehicle that
prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
