Page 492 of 635
SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interference
from another radar source, making it impossible
to detect a vehicle ahead, the PFCW system is
automatically turned off.
The FEB system warning light (orange) will illu-
minate.
Action to take
When the above conditions no longer exist, the
PFCW system will resume automatically.
Condition B
When the sensor area of the front bumper is
covered with dirt or is obstructed, making it im-
possible to detect a vehicle ahead, the PFCW
system is automatically turned off.
The FEB system warning light (orange) will illu-
minate and the “front radar obstruction” warning
message will appear in the vehicle information
display.

Action to take
If the warning light (orange) comes on, stop the
vehicle in a safe place, place the shift lever in the
P (Park) position and turn the engine off. Clean
the radar cover on the lower grille with a soft
cloth, and restart the engine. If the warning light
continues to illuminate, have the PFCW system
checked. It is recommended that you visit an
INFINITI retailer for this service.
NOTE:
If the FEB system stops working, the PFCW
system (if so equipped) will also stop work-
ing.
SYSTEM MALFUNCTION
If the PFCW system malfunctions, it will be
turned off automatically, a chime will sound, the
FEB system warning light (orange) will illuminate
and the warning message [Malfunction] will ap-
pear in the vehicle information display.
Action to take
If the warning light (orange) comes on, stop the
vehicle in a safe location, turn the engine off and
restart the engine. If the warning light continues
to illuminate, have the PFCW system checked. It
is recommended that you visit an INFINITI retailer
for this service.
SYSTEM MAINTENANCE
The sensorAis located behind the lower grille
of the front bumper.
To keep the system operating properly, be sure to
observe the following:
●Always keep the sensor area of the front
bumper clean.
●Do not strike or damage the areas around
the sensor.
●Do not cover or attach stickers or similar
objects on the front bumper near the sensor
area. This could cause failure or malfunction.●Do not attach metallic objects near the sen-
sor area (brush guard, etc.) . This could
cause failure or malfunction.
●Do not alter, remove or paint the front bum-
per. Before customizing or restoring the
front bumper, it is recommended that you
visit an INFINITI retailer.

●Keep your engine tuned up.
●Follow the recommended scheduled main-
tenance.
●Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
●Keep all the wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
●Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.If any malfunction occurs in the Intelligent AWD
system while the engine is running, messages are
displayed in the meter.
If the AWD error warning message is displayed,
there may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have your
vehicle checked as soon as possible. It is recom-
mended that you visit an INFINITI retailer for this
service.

INCREASING FUEL ECONOMY INTELLIGENT ALL-WHEEL DRIVE
(AWD) (if so equipped)

Page 497 of 635

The AWD high temperature message may be
displayed while trying to free a stuck vehicle due
to increased oil temperature. The driving mode
may change to 2-wheel drive. If this message is
displayed, stop the vehicle with the engine idling,
as soon as it is safe to do so. Then if the message
turns off, you can continue driving.The tire size message may be displayed if there is
a large difference between the diameters of front
and rear wheels. Pull off the road in a safe area,
with the engine idling. Check that all tire sizes are
the same, that the tire pressure is correct and that
the tires are not excessively worn.
If any warning messages continue to be dis-
played, have your vehicle checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
●Do not drive beyond the performance
capability of the tires. Accelerating
quickly, sharp steering maneuvers or
sudden braking may cause loss of con-
trol, even with Intelligent AWD
engaged.
●For AWD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious personal injury or vehicle
damage.

●Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure that you inform the
test facility personnel that your vehicle
is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious personal injury or vehicle
damage.
CAUTION
●Do not operate the engine on a free
roller when any of the wheels are
raised.
●If you use the free roller, rotate four
wheels with the same speed without
raising any wheels.●If an AWD warning message is dis-
played while driving there may be a
malfunction in the AWD system. Reduce
the vehicle speed immediately and have
your vehicle checked as soon as pos-
sible. It is recommended that you visit
an INFINITI retailer for this service.
●The powertrain may be damaged if you
continue driving when the AWD tem-
perature or tire size incorrect messages
are displayed
●If the AWD high temperature message
is displayed while you are driving, pull
off the road in a safe area, and idle the
engine. The driving mode will change to
2WD to prevent the AWD system from
malfunctioning. If the warning message
turns off, you can drive again.
●If the tire size incorrect message is dis-
played while you are driving, pull off the
road in a safe area with the engine
idling. Check that all tire sizes are the
same, that the tire pressure is correct
and that the tires are not excessively
worn.●If a warning message continues to be
displayed after the above operations,
have your vehicle checked as soon as
possible. It is recommended that you
visit an INFINITI retailer for this service.

The sonar (parking sensor) system sounds a tone
to inform the driver of obstacles near the bumper.
When the “DISPLAY” key is ON, the sonar view
will automatically appear in the meter.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
●The sonar system is not a replacement
for proper driving procedures and is not
designed to prevent contact with ve-
hicles or objects.●The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
●This function is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
If your vehicle sustains damage to the bumper
fascia, leaving it misaligned or bent, the sensing
zone may be altered causing inaccurate mea-
surement of obstacles or false alarm.
CAUTION
●Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard
●Keep the sonar sensors (located on the
bumper fascias) free from snow, ice and
large accumulations of dirt. Do not
clean the sensors with sharp objects. If
the sensors are covered, the accuracy of
the sonar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever is in
the D (Drive) position and both front and rear
obstacles when the shift lever is in the R (Re-
verse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change. The
tone will stop when the obstacle get away from
the vehicle.
