2019 INFINITI QX50 Owners Manual

If the radar sensorBdetects a slower mov-
ing 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
throttle and applies the brakes (up to ap-
proximately 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
from the vehicle in front of you and can re-
duce the speed to match a slower vehicle
ahead. The system will decelerate the vehicle
as necessary and if the vehicle ahead comes
to a stop, the vehicle decelerates to a stand-
still. However, the ICC system can only apply
up to 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 be-
tween 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 (24 km/h) and a vehicle is not
detected ahead. The system will also disen-
gage when the vehicle goes above the maxi-
mum set speed.
For additional information, refer to “Ap-
proach warning” in this section.
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 be-
tween approximately 20 and 90 mph (32
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 the driver, from the
vehicle ahead. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the sys-
tem. 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 sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic con-
gestion.
5-88Starting and driving

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 a
vehicle ahead, this system automatically ac-
celerates or decelerates your vehicle accord-
ing to the speed of the vehicle ahead. De-
press the accelerator to properly accelerate
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 sud-
den braking or if a vehicle cuts in. Always stay
alert when using the ICC system.VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
SWITCHES
The system is operated by the ICC switch and
four control switches, all mounted on the
steering wheel.
1. RES+ switch:
Resumes set speed or increases speed
incrementally.

∙ Long
∙ Middle
∙ Short
3. CANCEL switch:
Deactivates the system without erasing
the set speed.
4. ICC switch:
Master switch to activate the system.
5. SET- switch:
Sets desired cruise speed or reduces
speed incrementally.
Vehicle-to-vehicle distance control
mode display and indicators
The display is located between the speedom-
eter and tachometer.
1. This indicator indicates the ICC system status depending on a color:
∙ ICC system ON indicator (gray): Indi-
cates that the ICC switch is on.
∙ ICC system SET indicator (green): In-
dicates that the cruising speed is set.
∙ ICC system warning (yellow): Indi-
cates that there is a malfunction in the
ICC system. 2. Set vehicle speed indicator:
Indicates the set vehicle speed.
For Canadian models, the speed is dis-
played in km/h.
3. Set distance indicator: Displays the selected distance between
vehicles set with the distance switch.
4. Vehicle ahead detection indicator: Indicates whether it detects a vehicle in
front of you.

ger slipping.)
1System set display with vehicle ahead
2System set display without vehicle ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem 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 dis-
tance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may be
heard. 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 con-
trols the distance to that vehicle.

5-92Starting and driving

When a vehicle is no longer detected under
approximately 15 mph (24 km/h), the system
will be canceled.When passing another vehicle,the set speed
indicator
Bwill 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 re-
leased, the vehicle will return to the previ-
ously 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
speed
To cancel the preset speed, use one of the
following 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 ICC switch off. The ICC indica- tors 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 SET– switch.
∙ Push and hold the RES+ switch. The set vehicle speed will increase by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the RES+ switch. Each time you do this, the set
speed will increase by approximately
1 mph (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 SET– switch and release it.
∙ Push and hold the SET– switch. The set vehicle speed will decrease by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release the SET– switch. Each time you do this, the set
speed will decrease by approximately
1 mph (1 km/h).
To resume the preset speed, push and re-
lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 20 mph (32 km/h).
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
Each time the distance
switchAis
pushed, the set distance will change to long,
middle, short and back to long again, in that
sequence.
Distance Approximate distance at
60 mph (100 km/h) [ft (m)]
1. Long 200 (60)
2. Middle 150 (45)
3. Short 100 (30)
∙ 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.”)
