INFINITI QX80 2023 Owners Manual

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.

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).
. Push down the control switch to SET-
and then quickly release it. Each time you
do this, the set speed will decrease by
approximately 1 MPH (1 km/h for Ca-
nada).
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 20 MPH (30
km/h).

How to change set distance to
vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
Each time the DISTANCE switch
is
pushed, the set distance will change to long,
middle, short and back to long again in that
sequence.WAF0310X
. The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
. If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes
“long”.)Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle or if another vehicle cuts in, the
system warns the driver with the chime and
ICC system display. Decelerate by depres-
sing the brake pedal to maintain a safe

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
Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
. The system is primarily intended for
use on straight, dry, open roads with
light traffic. It is not advisable to use
the system in city traffic or con-
gested areas.
. This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing
traffic. Do not use the system on
roads with sharp curves, or on icy
roads, in heavy rain or in fog.
. As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over-

come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
. 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
that the vehicle has come to a
standstill and sound a warning chime.
To prevent the vehicle from moving,
the driver must depress the brake
pedal.
. Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-
stances.
. The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions: — On roads where the traffic is
heavy or there are sharp curves
— On slippery road surfaces such as on ice or snow, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (the vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)
— On repeated uphill and downhill roads
— When traffic conditions make it difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
. Do not use the ICC system if you are
towing a trailer. The system may not
detect a vehicle ahead.
. In some road or traffic conditions, a
vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. You
may need to control the distance
from other vehicles using the accel-
erator pedal. Always stay alert and avoid using the ICC system when it is
not recommended in this section.
The radar sensor will not detect the follow-
ing objects:
. Stationary and slow moving vehicles
. Pedestrians or objects in the roadway
. Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system may
not maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. When excessively heavy baggage is
loaded in the rear seat or the luggage
area of your vehicle
. When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation within the
limitation of the system. When the sensor
is covered with dirt or is obstructed, the
system will automatically be canceled. If the
sensor is covered with ice, a transparent or
