2014 INFINITI QX80 brake

under the following conditions. To avoid
accidents, never use the ICC system
under the following conditions:
—On roads where the traffic is heavyor there are sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—On off-road surfaces such as onsand or rock, etc.
—During bad weather (rain, fog, snow,
etc.)
—When the windshield wipers areoperating at high speed. The system
may cancel when the wipers are set
to the AUTO position.
—When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (the vehi-cle may go beyond the set vehicle
speed and frequent braking may
result in overheating the brakes)
—On repeated uphill and downhillroads
—When traffic conditions make itdifficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration
—When towing a trailer or othervehicle
. 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 accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE OPERATION
Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance. The
vehicle-to-vehicle distance control mode of
the Intelligent Cruise Control (ICC) system
may not be able to maintain the selected
distance between vehicles (following dis-
tance) or selected vehicle speed under
some circumstances.
The vehicle-to-vehicle distance control
mode uses a sensor
*Alocated on the
front of the vehicle to detect vehicles

To set cruising speed,accelerate your
vehicle to the desired speed, push the
COAST/SET switch and release it. (Vehicle
ahead detection indicator, set distance
indicator and set vehicle speed indicator
come on.) Take your foot off the accelerator
pedal. Your vehicle will maintain the set
speed.

When the COAST/SET switch is pushed
under the following conditions, the system
cannot be set and the set vehicle speed
indicator will blink for approximately 2
seconds:
. When traveling below 20 MPH (32
km/h) and a vehicle ahead is not
detected
. When the shift lever is not in the D or
Manual mode
. When the windshield wipers are operat-
ing at high speed. The system may
cancel when the wipers are set to the
AUTO position. .

System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according 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 Intelligent Cruise Control (ICC)
system.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.
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 acceler-
ates 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.
Starting and driving5-67

5-68Starting and driving
If a vehicle ahead appears during accel-
eration 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 (24 km/h), the
system will be cancelled.
SSD1108
When passing another vehicle,the set
vehicle 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 and release the COAST/SET
switch.
. Push and hold the ACCELERATE/RE-
SUME switch. The set vehicle speed
will increase by approximately 5 MPH
or 5 km/h.
. Push, then quickly release the ACCEL-
ERATE/RESUME switch. Each time you
do this, the set speed will increase by
approximately 1 MPH or 1 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
the COAST/SET switch and release it.
. Push and hold the COAST/SET switch.
The set vehicle speed will decrease by

5-70Starting and driving
SSD1109
.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 Intelligent Cruise Control (ICC) system
display. Decelerate by depressing 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
between 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 vehi-
cles is increasing
. When a vehicle cuts in near your vehicle
The warning chime will not sound in the
following cases:
. When your vehicle approaches vehicles
that are parked or moving slowly
. When the accelerator pedal is de-
pressed, overriding the system

SSD0284A
NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects some reflectors
*A
which are fitted on vehicles in other lanes
or on the side of the road. This may cause
the ICC system to decelerate or accelerate
the vehicle. The ICC sensor may detect
these reflectors when the vehicle is driven
on winding roads, hilly roads or when
entering or exiting a curve. The ICC sensor
may also detect reflectors on narrow roads
or in road construction zones. 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 con-
ditions and the control is automatically
canceled.
.
When the vehicle speed falls below
approximately 15 MPH (24 km/h)
. When the system judges the vehicle is
at a standstill
. When the shift lever is shifted to the N
(Neutral) position
. When the windshield wipers are operat-
ing at high speed. The system may
cancel when the wipers are set to the
AUTO position.
. When the VDC is turned off
. When the ABS or VDC operates
. 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 driving into a strong light (for
example, sunlight)
. When distance measurement becomes
impaired due to adhesion of dirt or
obstruction to the sensor

Warning light
When the system is not operating properly,
the chime sounds and the system warning
light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and then
perform the setting again.
If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is
still driveable under normal conditions,
have the vehicle checked at an INFINITI retailer.
PREVIEW FUNCTION (for Intelligent
Cruise Control (ICC) system
equipped model)
The Intelligent Cruise Control (ICC) system
with the preview function identifies the
need to apply emergency braking by
sensing the vehicle ahead in the same
lane and the distance to the vehicle ahead
and relative speed from it, it applies the
brake pre-pressure before the driver de-
presses the brake pedal and helps improve
brake response by reducing pedal free
play.
