2023 INFINITI QX80 light

.In the case of several vehicles approach-
ing in a row (Illustration 1) or in the
opposite direction (Illustration 2), a
chime may not be issued to the BCI
system after the first vehicle passes the
sensors.
. The sonar system chime indicating there
is an object behind the vehicle has a
higher priority than the BCI chime (single
beep) indicating an approaching vehicle.
If the sonar system detects an object
behind the vehicle and the BCI system
detects an approaching vehicle at the
same time, the following indications are
provided:
— The sonar system chime sounds
— The side indicator light on the side of the approaching vehicle flashes, and
— A yellow rectangular frame appears in the touch screen display.

If an approaching vehicle or close object
behind the vehicle is detected when your
vehicle is backing up, a red frame
will
appear in the touch screen display and the
system will chime three times. Then, the
brakes will be applied momentarily. After the
automatic brake application, the driver must
depress the brake pedal to maintain brake
pressure.
If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward before the braking is applied.
However, if you continue to accelerate, the
system will not engage the brakes.
The BCI system does not operate if the
object is very close to the bumper.

SYSTEM MAINTENANCE
The two radar sensorsfor the BCI system
are located near the rear bumper. Always
keep the area near the radar sensors clean.
The radar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors.

about 1 MPH (1.6 km/h).
To resume the preset speed, push up the
control switch to RES+ and release it. The vehicle will resume the last set cruising speed
when the vehicle speed is over 25 MPH (40
km/h).WARNING
Failure to follow the warnings and
instructions for proper use of the ICC
system could result in serious injury or
death.
.
ICC is not a collision avoidance or
warning device. For highway use only
and it is not intended for congested
areas or city driving. Failure to apply
the brakes could result in an accident.
. Always observe posted speed limits
and do not set the speed over them.
. Always drive carefully and atten-
tively when using either cruise con-
trol mode. Read and understand the
Owner’s Manual thoroughly before
using the cruise control. To avoid
serious injury or death, do not rely
on the system to prevent accidents or
to control the vehicle’s speed in
emergency situations. Do not use
cruise control except in appropriate
road and traffic conditions.
. In the conventional (fixed speed)
cruise control mode, a warning chime
will not sound to warn you if you are
too close to the vehicle ahead. Pay
special attention to the distance
between your vehicle and the vehicle

WAF0308X
System set display with vehicle ahead
System set display without vehicle
ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.
Vehicle detected ahead:
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying the
brakes to match the speed of a slower
vehicle ahead. The system then controls the vehicle speed based on the speed of the
vehicle ahead to maintain the driver selected
distance.
NOTE:
.
The stoplights of the vehicle come on
when braking is performed by the ICC
system.
. When the brake operates, a noise may be
heard and/or vibration may be felt. This
is not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes on.
The ICC system will also display the set
speed and selected distance. Vehicle ahead not detected:
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the
set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (25 km/h), the
system will be canceled.

WAF0309X
When passing another vehicle,the set speed
indicator will flash when the vehicle speed
exceeds the set speed. The vehicle detect
indicator will turn off when the area ahead
of the vehicle is open. When the pedal is
released, the vehicle will return to the
previously set speed.
Even though your vehicle speed is set in the
ICC system, you can depress the accelerator
pedal when it is necessary to accelerate your
vehicle rapidly.
How to change set vehicle speed
To cancel the preset speed, use any of these
methods:
. Push the CANCEL switch. The set vehicle
speed indicator will go out.
. Tap the brake pedal. The set vehicle
speed indicator will go out.
. Turn the MAIN switch off. Both the
MAIN switch indicator and set vehicle
speed indicator will go out.
To reset at a faster cruising speed, use one
of the following methods:
. Depress the accelerator pedal. When the
vehicle attains the desired speed, push
down the control switch to SET- and
release it.
. Push up and hold the control switch to
RES+. The set vehicle speed will increase
by approximately 5 MPH (5 km/h for
Canada).
. Push up the control switch to RES+ and
then quickly release it. Each time you do
this, the set speed will increase by
approximately 1 MPH (1 km/h for Ca-
nada).
To reset at a slower cruising speed, use one
of the following methods:
. Lightly tap the brake pedal. When the
vehicle attains the desired speed, push
down the conrtol switch to SET- and release it.
. Push down and hold the control switch to
SET-. The set vehicle speed will decrease
by approximately 5 MPH (5 km/h for
Canada).

vehicle distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
The warning chime may not sound in some
cases when there is a short distance be-
tween vehicles. Some examples are:
. When the vehicles are traveling at the
same speed and the distance between
vehicles is not changing
. When the vehicle ahead is traveling
faster and the distance between vehicles
is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound when:
. Your vehicle approaches other vehicles
that are parked or moving slowly.
. The accelerator pedal is depressed, over-
riding the system.
NOTE:
The approach warning chime may sound
and the system display may blink when the
radar sensor detects objects on the side of
the vehicle or on the side of the road. This
may cause the ICC system to decelerate or
accelerate the vehicle. The radar sensor may
detect these objects when the vehicle is
driven on winding roads, narrow roads, hilly
roads or when entering or exiting a curve. In
these cases you will have to manually control the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or
vehicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed.
.
When the vehicle ahead is not detected
and your vehicle is traveling below the
speed of 15 MPH (25 km/h)
. When the system judges the vehicle is at
standstill
. When the shift lever is not in the D (Drive)
or manual shift mode
. When the parking brake is applied
. When the SNOW mode switch is pushed
on
. When the 4WD shift switch is in the 4H
or 4L position (for 4WD models)
. When the VDC system is turned off
. When the VDC (including the traction
control system) operates
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor .
When a wheel slips
. When the radar signal is temporarily
interrupted
