2023 INFINITI QX80 brake

.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.
WAE0786X
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.

.The radar sensors detect approach-
ing (moving) vehicles. The radar sen-
sors cannot detect every object such
as:
— Pedestrians, bicycles, animals or child operated toy vehicles
— A vehicle that passing at speeds greater than approximately 15
MPH (24 km/h)
. The radar sensors may not detect
approaching vehicles in certain situa-
tions:
— Illustration a. When a vehicle parked next to you obstructs the
beam of the radar sensor.
— Illustration b. When the vehicle is parked in an angled parking space.
— Illustration c. When the vehicle is parked on inclined ground.
— Illustration d. When an approach- ing vehicle turns into your vehi-
cle’s parking lot aisle.
— Illustration e. When the angle formed by your vehicle and ap-
proaching vehicle is small.
. The following conditions may reduce
the ability of the radar sensors to
detect other vehicles: — Severe weather
— Road spray
— Ice/frost/dirt build up on the
vehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar
sensors to detect other vehicles.
. The sonar sensors detect stationary
objects behind the vehicle. The sonar
sensor may not detect:
— Small or moving objects
— Wedge-shaped objects
— Object close to the bumper (less than approximately 1 ft (30 cm))
— Thin objects such as rope, wire and chain, etc.
. The brake engagement by the BCI
system is not as effective on a slope
as it is on flat ground. When on a
steep slope the system may not
function properly.
. Do not use the BCI system under the
following conditions because the sys-
tem may not function properly. — When driving with a tire that is
not within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
. When towing a trailer or other ve-
hicle, turn the BCI system off to
prevent the occurrence of an unex-
pected accident resulting from sud-
den system operation. (See “BCI
system operation” (P.5-55).)
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accelerator
pedal.
To turn on the cruise control, push the
MAIN switch on. The cruise indicator (white)
illuminates in the vehicle information display.
To set cruising speed, accelerate yourvehicle to the desired speed, push down
the conrtol switch to SET- and release it.
The cruise indicator (green) illuminates in the
vehicle information display. Take your foot
off the accelerator pedal. Your vehicle will
maintain the set speed.
.
To pass another vehicle, depress the
accelerator pedal. When you release the
pedal, the vehicle will return to the
previously set speed.
. The vehicle may not maintain the set
speed on winding or hilly roads. If this
happens, drive without the cruise con-
trol.
To cancel the preset speed, follow any of
these methods:
. Push the CANCEL switch.
. Tap the brake pedal.
. Turn the MAIN switch off.
After any of the above operations is per-
formed, the color of the cruise indicator will
change from green to white.
. If you depress the brake pedal while
pushing up or down the control switch
and reset the cruising speed, the cruise
control will disengage. Turn the MAIN
switch off once and then turn it on again.
. The cruise control will automatically
cancel if the vehicle slows more than 8
MPH (13 km/h) below the set speed.

.If you move the shift lever to N (Neutral)
position, the cruise control will be can-
celed.
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 conrtol switch to SET- and
release it.
. Push up and hold the control switch to
RES+. When the vehicle attains the
speed you desire, release the switch.
. Push up the control switch to RES+ and
then quickly release it. Each time you do
this, the set speed will increase by about
1 MPH (1.6 km/h).
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-. Release the switch when the
vehicle slows down to the desired speed.
. Push down the control switch to SET-
and then quickly release it. Each time you
do this, the set speed will decrease by
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
INTELLIGENT CRUISE CONTROL
(ICC) (if so equipped)

JVS1154X
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the radar sensor
detects a slower
moving vehicle ahead, the system will reduce
the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.
Vehicle-to-vehicle distance control
mode operation
The vehicle-to-vehicle distance control
mode is designed to maintain a selected
distance and reduce the speed to match the
slower vehicle ahead; the system will de-
celerate the vehicle as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the ICC
system can only apply up to approximately
40% of the vehicle’s total braking power.
This system should only be used when traffic
conditions allow vehicle speeds to remain
fairly constant or when vehicle speeds
change gradually. If a vehicle moves into
the traveling lane ahead or if a vehicle
traveling ahead rapidly decelerates, the
distance between vehicles may become
closer because the ICC system cannot
decelerate the vehicle quickly enough. If this
occurs, the ICC system will sound a warning
chime and blink the system display to notify
the driver to take necessary action.
The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 MPH (25 km/h) and a vehicle is
not detected ahead. The system will also
disengage when the vehicle goes above the
maximum set speed.
See “Approach warning” (P.5-74). The following items are controlled in the
vehicle-to-vehicle distance control mode:
.
When there are no vehicles traveling
ahead, the vehicle-to-vehicle distance
control mode maintains the speed set
by the driver. The set speed range is
between approximately 20 and 90 MPH
(30 and 144 km/h).
. When there is a vehicle traveling ahead,
the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by driver, from the
vehicle ahead. The adjusting speed range
is up to the set speed. If the vehicle
ahead comes to a stop, the vehicle
decelerates to a standstill within the
limitations of the system. The system
will cancel once it judges a standstill with
a warning chime.
. When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach
stationary and slow moving vehicles. You
must pay attention to vehicle operation to
maintain proper distance from vehicles
ahead when approaching toll gates or traffic
congestion.

When driving on the freeway at a set speed
and approaching a slower traveling vehicle
ahead, the ICC system will adjust the speed
to maintain the distance, selected by the
driver, from the vehicle ahead. If the vehicle
ahead changes lanes or exits the freeway,
the ICC system will accelerate and maintain
the speed up to the set speed. Pay attention
to the driving operation to maintain control
of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed
on winding or hilly roads. If this occurs, you
will have to manually control the vehicle
speed.
Normally when controlling the distance to avehicle ahead, this system automatically
accelerates or decelerates your vehicle ac-
cording to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the
brake pedal when deceleration is required
to maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when using
the ICC system.

detected
. When the shift lever is not in the D (Drive)
or manual shift mode
. When the parking brake is applied
. When the brakes are operated by the

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.
