2023 INFINITI QX80 warning light

5-102Starting and driving
SSD0253
When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction or on a slope,
the sensor may detect vehicles in a different
lane, or may temporarily not detect a vehicle
traveling ahead. This may cause the system
to work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the system
may warn you by blinking the system
indicator and sounding the chime unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.SYSTEM TEMPORARILY UNA-
VAILABLE

SYSTEM MAINTENANCE
The radar sensoris located on the front of
the vehicle. The camerais located on the
upper side of the windshield.
To keep the FEB with Pedestrian Detection
system operating properly, be sure to ob-
serve the following:
. Always keep the sensor area on the front
of the vehicle and windshield clean.
. Do not strike or damage the areas around
the sensors (ex. bumper, windshield).
. Do not cover or attach stickers or similar
objects on the front of the vehicle near
the sensor area. This could cause failure
or malfunction.

.Do not attach metallic objects near the
radar sensor area (brush guard, etc.).
This could cause failure or malfunction.
. Do not place reflective materials, such as
white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
detection capability.

WARNING
Failure to follow the warnings and
instructions for proper use of the PFCW
system could result in serious injury or
death.
.The PFCW system helps warn the
driver before a collision but will not
avoid a collision. It is the driver’s
responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
The PFCW system can help alert the driver
when there is a sudden braking of a second
vehicle traveling in front of the vehicle ahead
in the same lane.
JVS1154X
The PFCW system uses a radar sensorlocated on the front of the vehicle to
measure the distance to a second vehicle
ahead in the same lane.

.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
. Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-6).)
WARNING
. Do not attempt to raise two wheels
off the ground and shift the trans-
mission to any drive or reverse posi-
tion with the engine running. Doing
so may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel dy-
namometer or similar equipment even
if the other two wheels are raised off
the ground. Make sure you inform
test facility personnel that your ve-
hicle is equipped with 4WD before it
is placed on a dynamometer. Using
the wrong test equipment may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury.
CAUTION
.Do not drive the vehicle in the 4HI or
4LO position on dry hard surface
roads. Driving on dry, hard surfaces in 4HI or 4LO may cause unnecessary
noise, tire wear and increased fuel
consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driving
on dry hard surface roads:
— in the 4HI position, shift the 4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmission
lever to the N (Neutral) position
with the brake pedal depressed
and shift the 4WD shift switch to
AUTO.
If the 4WD warning light is still on
after the above operation, have
your vehicle checked. It is recom-
mended you visit an INFINITI
retailer for this service.
. The transfer case may be damaged if
you continue driving with the 4WD
warning light blinking.
See “On-pavement and off-road driving
precautions” (P.5-8) for other precautions
for offroad driving.
