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.

LANE CAMERA UNIT MAINTENANCE
The lane camera unit*1for the LDW/LDP
system is located inside the map light
cover. To keep the proper operation of the
LDW/LDP systems and prevent a system
malfunction, be sure to observe the follow-
ing:
. Always keep the windshield clean.
. Do not attach a sticker (including
transparent material) or install an
accessory near the camera unit.
. Do not place reflective materials, such
as white paper or a mirror, on the
instrument panel. The reflection of sunlight may adversely affect the cam-
era unit’s capability of detecting the
lane markers.
. Do not strike or damage the areas
around the camera unit. Do not touch
the camera lens or remove the screw
located on the camera unit. If the
camera unit is damaged due to an
accident, contact an INFINITI retailer. The Blind Spot Warning (BSW) system can
help alert the driver of other vehicles in
adjacent lanes when changing lanes.

FCW system operation
The FCW system will function at speeds of
approximately 10 MPH (15 km/h) and
above, when the system turns on.
The FCW system has an automatic setting
mode and a manual setting mode to turn
the system on. The setting mode can be
changed. In the automatic setting mode,
the FCW system is automatically turned on
when the ignition switch is pushed to the
ON position. When the FCW system is on,
the warning systems ON indicator light
*1
on the warning systems switch illuminates.
To cancel the FCW system, push thewarning systems switch. The warning
systems ON indicator light will turn off. To
turn on the system, push the warning
systems switch again.
When the warning systems switch is
pushed, the LDW and BSW systems will
also turn on or off simultaneously. See
“Lane Departure Warning (LDW) system”
(P.5-20) and
“Blind Spot Warning (BSW)
system” (P.5-27).
In the manual setting mode, you need to
push the warning systems switch to turn
on the system after the ignition switch is
pushed to the ON position.
The setting mode can be changed using
the warning systems switch. To change the
setting mode, push and hold the warning
systems switch for more than 4 seconds
when the warning systems ON indicator is
off. When the mode is changed, a chime
sounds and the lane departure warning
light (orange) flashes.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” (P.5-36). The Intelligent Brake Assist (IBA) system
warns the driver by a warning light and
chime when there is a risk of a collision
with the vehicle ahead in the traveling lane
and the driver must take avoidance action
immediately. The system helps reduce the
rear-end collision speed by applying the
brakes when the system judges that the
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above, and
when your vehicle is driven at speeds
approximately 10 MPH (15 km/h) faster
than the vehicle ahead.
