The warning systems switch will turn on
and off the Lane Departure Warning (LDW)
system and the Forward Collision Warning
(FCW) system at the same time.
The LDW system will sound a warning
chime and blink the lane departure warn-
ing light (orange) to alert the driver if the
vehicle is traveling close to either the left
or the right of a traveling lane with
detectable lane markers. (See“Lane De-
parture Warning (LDW) system/Lane De-
parture Prevention (LDP) system” (P.5-21).)
The FCW system will sound a warning
chime and the vehicle ahead detection
indicator light blinks to alert the driver if the vehicle is traveling close to the vehicle
ahead. (See
“Forward Collision Warning
(FCW) system” (P.5-67).)
The warning systems switch is automati-
cally turned on when the engine is started,
and the warning systems ON indicator
*1on the switch illuminates.
To cancel the warning systems, push the
warning systems switch to turn off the
system. The warning systems ON indicator
will turn off.

equipped)

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.5-11).
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.
For information regarding replacement of a
battery, see “Intelligent Key battery repla-
cement” (P.8-27).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.

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.
