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.
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 canceled.

SSD0611

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 the set vehicle

.

The distance to the vehicle ahead will

change according to the vehicle speed.
The higher the vehicle speed, the long-
er 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
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 when:
.

the vehicle approaches other vehicles

that are parked or moving slowly.

.

the accelerator pedal is depressed,

overriding the system.

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 ahead is not detected

and your vehicle is traveling below the
speed of 15 MPH (24 km/h)

.

When the system judges the vehicle is

at standstill

.

When the shift lever is not in the D, DS

or Manual mode

.

When the windshield wipers are operat-

ing at low (LO) or high speed (HI). If the
vehicle is equipped with a rain-sensing
auto wiper, the system may cancel
when the wipers are operating at the
intermittent (INT) speed.

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 congested areas.

.

This system will not adapt automatically
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.

Condition:

(383,1)

Model: 2017MY INFINITI QX70(S51) OM17E00S51U0 ]

.

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 overcome
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 surrounding circumstances in order
to maintain 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 operation of
the vehicle and be ready to manually
control the proper following distance.
The vehicle-to-vehicle distance control
mode of the ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances.

.

The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, 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 the windshield wiper is oper-

ated at the low speed (LO) or high
speed (HI) position, the ICC system is
automatically canceled. If the vehicle
is equipped with a rain-sensing auto
wiper, the system may cancel when
the wipers are operating at the
intermittent (INT) speed.

— When strong light (for example, at

sunrise or sunset) is directly shining
on the front of the vehicle

— When rain, snow or dirt adhere to

the 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 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 accelerator pedal. Always stay
alert and avoid using the ICC system
when it is not recommended in this
section.

The distance sensor will not detect the
following 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

Starting and driving

The sensor generally detects the signals
returned from the reflectors on a vehicle
ahead. Therefore, if the sensor cannot
detect the reflector on 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 reflector of the vehicle ahead

is positioned high on the vehicle
(trailer, etc.)

.

When the reflector on the vehicle ahead

is missing, damaged or covered

.

When the reflector of the vehicle ahead

is covered with dirt, snow and road
spray

.

When the snow or road spray from

traveling vehicles reduces the sensor’s
visibility

.

When dense exhaust or other smoke

(black smoke) from vehicles reduces
the sensor’s visibility

.

When excessively heavy baggage is

loaded in the rear seat or the luggage
room of your vehicle

The ICC system is designed to automati-
cally 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 translucent vinyl bag, etc.,
the ICC system may not detect them. In
these instances, the vehicle-to-vehicle dis-
tance control mode may not cancel and
may not be able to maintain the selected
following distance from the vehicle ahead.
Be sure to check and clean the sensor
regularly.

Condition:

(385,1)

Model: 2017MY INFINITI QX70(S51) OM17E00S51U0 ]

SSD0252

The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the
detection zone for the vehicle-to-vehicle
distance detection mode to maintain the
selected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane. If this occurs, the ICC system may
warn you by blinking the system indicator

and sounding the chime. The driver may
have to manually control the proper dis-
tance away from vehicle traveling ahead.

SSD0253

When driving on some roads, such as
winding, hilly, curved, narrow roads, or
roads which are under construction, the
ICC sensor may detect vehicles in a
different lane, or may temporarily not
detect a vehicle traveling ahead. This may
cause the ICC system to decelerate or
accelerate the vehicle.
The detection of vehicles may also be
affected by vehicle operation (steering
maneuver or traveling position in the lane,
etc.) or vehicle condition. If this occurs, the
ICC system may warn you by blinking the
system indicator and sounding the chime
unexpectedly. You will have to manually

control the proper distance away from the
vehicle traveling ahead.
