2018 INFINITI QX60 sensor

The RCTA system uses radar sensors1in-
stalled on both sides near the rear bumper to
detect an approaching vehicle.
The radar sensors
1can detect an ap-
proaching vehicle from up to approximately
20 m (66 ft) away.

WARNING
Listed below are the system limitations for
the RCTA system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
∙ Always check surroundings and turn tocheck what is behind you before backing
up. The radar sensors detect approaching
(moving) vehicles. The radar sensors can-
not detect every object such as:
– Pedestrians, bicycles, motorcycles, animals or child-operated toy vehicles
– A vehicle that is passing at speeds greater than approximately 30 km/h
(19 mph)
– A vehicle that is passing at speeds lower than approximately 8 km/h
(5 mph)
∙ The radar sensors may not detect ap- proaching vehicles in certain situations:
– 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 approaching vehicle turns into your vehicle’s park-
ing lot aisle.
– Illustration e: When the angle formed by your vehicle and approaching ve-
hicle is small.
∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/dirt build-up on the vehicle
∙ Do not attach stickers (including trans- parent material), install accessories or
apply additional paint near the radar sen-
sors. These conditions may reduce the
ability of the radar to detect other
vehicles.
∙ Excessive noise (e.g., audio system vol- ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard. NOTE:
In the case of several vehicles approaching in
a row (Illustration 1) or in the opposite direc-
tion (Illustration 2), a chime may not be
sounded by the RCTA system after the first
vehicle passes the sensors.

The radar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the radar sensors.
NOTE:
If the BSW system stops working, the RCTA
system will also stop working.
Action to take
When the above conditions no longer exist,
the system will resume automatically.
Malfunction
When the RCTA system malfunctions, it will
turn off automatically. The system malfunc-
tion warning message with the BSW/RCTA
indicator (orange) will appear in the vehicle
information display.
NOTE:
If the BSW system stops working, the RCTA
system (if so equipped) will also stop work-
ing.Action to take
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage continues to appear, have the system
checked. It is recommended that you visit an
INFINITI retailer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the radar
sensors clean.
The radar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors.

5-76Starting and driving

The ICC system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and direc-
tion.
The ICC system uses a radar sensor
Alo-
cated on the front of the vehicle to detect
vehicles traveling ahead.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the ve-
hicle speed so that your vehicle follows the
vehicle in front at the selected distance.
The detection range of the sensor is approxi-
mately 120 m (390 ft) ahead.
LSD2702
LSD2610
Starting and driving5-79

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.
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 accelerateyour 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.
ICC (Vehicle-to-vehicle distance
control) mode
In the vehicle-to-vehicle distance control
mode, the ICC system automatically main-
tains a selected distance from the vehicle
traveling in front of you according to that
vehicle’s speed (up to the set speed), or at the
set speed when the road ahead is clear.
The system is intended to enhance the opera-
tion 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 ve-
hicle 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 approximately 200 m (650 ft) ahead.
Preview Function
The ICC system with the Preview Function
identifies the need to apply emergency brak-
ing by sensing a vehicle ahead in the same
lane, and the distance and relative speed
from it. The system applies the brake pre-
pressure before the driver depresses the
brake pedal and helps improve brake re-
sponse by reducing pedal free play.
∙ This system will not operate when the vehicle is moving at approximately
32 km/h (20 mph) or less.
∙ The pre-pressure function ceases when the following conditions are met:
– When the driver depresses the accel- erator pedal or the brake pedal.
– If the driver does not operate the ac- celerator or brake pedal within ap-
proximately 1 second.

∙ The sensor will not detect:– Pedestrians or objects in the roadway
– Oncoming vehicles in the same lane
– Motorcycles traveling offset in thetravel lane as illustrated
WARNING
∙This system is only an aid to assist braking
operation and is not a collision warning or
avoidance device. It is the driver’s respon-
sibility to stay alert, drive safely and be in
control of the vehicle at all times.
∙ As there is a performance limit to the Pre- view Function, never rely solely on this system. This system does not correct
careless, inattentive or absentminded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Reduce
vehicle speed by depressing the brake
pedal, in order to maintain a safe distance
between vehicles.
∙ The system may not detect the vehicle in front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the following
conditions. The vehicle is still driveable
under normal conditions and the Brake
Assist will operate.
– When rain or snow adhere to the bum- per around the distance sensor
– Vehicle position in the lane may cause the sensor to temporarily not detect a
vehicle in the same lane or may detect
objects or vehicles in other lanes.
Conventional (fixed speed) cruise
control mode
This mode allows driving at a speed between
32 to 144 km/h (20 to 90 mph) for Mexico,
32 to 144 km/h (20 to 90 mph) for Taiwan or
32 to 189 km/h (20 to 117 mph) for Gulf
Coast Countries without keeping your foot
on the accelerator pedal.
WARNING
∙ In the conventional (fixed speed) cruisecontrol mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the presence
of the vehicle ahead nor the vehicle-to-
vehicle distance is detected.
∙ Pay special attention to the distance be- tween your vehicle and the vehicle ahead
of you or a collision could occur.
∙ Always confirm the setting in the Intelli- gent Cruise Control system display.
∙ Do not use the conventional (fixed speed) cruise control mode when driving under
the following conditions:
– when it is not possible to keep the ve- hicle at a set speed
– in heavy traffic or in traffic that varies in speed
– on winding or hilly roads
– on slippery roads (rain, snow, ice, etc.)
– in very windy areas
∙ Doing so could cause a loss of vehicle con- trol and result in an accident.

Distance Approximate distance at100 km/h (60 mph) [m (ft)]
1. Long 55 (180)
2. Middle 40 (130)
3. Short 25 (80)
∙ 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 ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if: ∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
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 vehicles
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, over- riding the system. NOTE:
The approach warning chime may sound and
the system display may blink when the ICC
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The ICC 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 ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
