2020 INFINITI QX60 brake sensor

If the radar detects an approaching vehicle
from the side, the system chimes a sound
(single beep), the side BSW/RCTA indicator
light on the side of the approaching vehicle
flashes and a yellow rectangular frame ap-
pears in the display
A.NOTE:
∙ In the case of several vehicles approach-
ing in a row (Illustration 1) or in the op-
posite direction (Illustration 2), a chime
may not be sounded by the BCI system
after the first vehicle passes the sensors.
∙
The sonar system chime indicating there is
an object behind the vehicle has a higher
priority than the BCI chime (single beep)
indicating an approaching vehicle. If the
sonar system detects an object behind the
vehicle and the BCI system detects an ap-
proaching vehicle at the same time the fol-
lowing indicators are provided:
– The sonar system chime sounds
– The side BSW/RCTA indicator light
on the side of the approaching vehicle
flashes and
– A yellow rectangular frame appears
in the display
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is back-
ing up, a red frame will appear in the display
Aand the system will chime three times.
Then, the brakes will be applied momentarily.

E: When the angle
formed by your vehicle and approach-
ing vehicle 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.
∙ The sonar sensors detect stationary ob- jects behind the vehicle. The sonar sensor
may not detect:
– Small or moving objects
– Wedge-shaped objects
– Objects close to the bumper (less than approximately 1 ft [30 cm]) – Thin objects such as rope, wire and
chain, etc.
∙ The brake engagement by the BCI system is not as effective on a slope as it is on flat
ground. When on a steep slope the sys-
tem may not function properly.
∙ Do not use the BCI system under the fol- lowing conditions because the system
may not function properly:
– When driving with a tire that is not within normal tire conditions (e.g., tire
wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
– When the vehicle is equipped with non-original brake parts or suspen-
sion parts.
∙ Do not use the BCI system when towing a trailer.
∙ Excessive noise (e.g., audio system vol- ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
SYSTEM TEMPORARILY NOT
AVAILABLE
If the following messages appear on the ve-
hicle information display, a chime will sound
and the BCI system will be turned off auto-
matically:
∙ “Unavailable: High Accelerator Temp.”: If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F [40°C]) and then
started, the BCI system may be deacti-
vated automatically and the “Unavailable:
High Accelerator Temp” message will ap-
pear in the vehicle information display for
a period of time.
When the interior temperature is re-
duced, turn off the BCI system and turn it
on again.
∙ “Unavailable: Side Radar Obstruction”: When side radar blockage is detected.
When the blockage is removed, turn off
the BCI system and turn it on again.

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.
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 650 ft (200 m) 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
20 mph (32 km/h) 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 brak-ing operation and is not a collision warn-
ing or avoidance device. It is the driver’s
responsibility 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
20 to 90 mph (32 to 144 km/h) 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.
THE ICC SWITCH
The system is operated by the CRUISE
ON/OFF switch and four control switches,
all mounted on the steering wheel.
1. ACCEL/RES switch:
Resumes set speed or increases speed
incrementally.
2. COAST/SET switch:
Sets desired cruise speed or reduces
speed incrementally.

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).

∙ As there is a performance limit to the dis-tance control function, never rely solely
on the ICC system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visibil-
ity in rain, fog, or other bad weather. De-
celerate the vehicle speed by depressing
the brake pedal, depending on the dis-
tance to the vehicle ahead and the sur-
rounding 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 operation of the vehicle and be ready to manually con-
trol the proper following distance. The
ICC system may not be able to maintain
the selected distance between 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 rain, snow or dirt adheres to the bumper around the distance sensor
– On steep downhill roads (the vehicle 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 diffi- cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
∙ Do not use the ICC system if you are tow- ing a trailer. The system may not detect a
vehicle ahead. ∙ In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert and
avoid using the ICC system where not
recommended in this warning section.
The radar 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
The following are some conditions in which
the sensor cannot properly detect a vehicle
ahead and the system may not operate prop-
erly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection.
∙ When excessively heavy baggage is loaded in the rear seat or the cargo area
of your vehicle.
The ICC system is designed to automatically
check the sensor’s operation within the limi-
tations of the system.

WARNING
Failure to follow the warnings and instruc-
tions for proper use of the DCA system
could result in serious injury or death.
∙ DCA helps maintain a distance to the ve-hicle in front under certain conditions. It
is not a collision avoidance system. Fail-
ure to apply the brakes could result in an
accident.
∙ Always drive carefully and attentively when using the DCA system. Read and
understand the Owner’s Manual thor-
oughly before using the DCA system. Do
not use the DCA system except in appro-
priate road and traffic conditions.
∙ 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 with a warning
chime. To prevent the vehicle from mov-
ing, the driver must depress the brake
pedal.
∙ The DCA system will not apply brake control while the driver’s foot is on the
accelerator pedal. The DCA system brakes and moves the ac-
celerator pedal upward according to the dis-
tance from and the relative speed of the ve-
hicle ahead to help assist the driver to
maintain a following distance.
DCA SYSTEM OPERATION
Always pay attention to the operation of the
vehicle and be ready to manually decelerate
to maintain the proper following distance.
The DCA system may not be able to deceler-
ate the vehicle under some circumstances.
The DCA system uses a sensor
Alocated
behind the front bumper of the vehicle to
detect vehicles traveling ahead. The sensor
generally detects the signals returned from
the vehicle ahead. Therefore, if the sensor
cannot detect the reflection from the vehicle
ahead, the DCA system may not operate.

DISTANCE CONTROL ASSIST (DCA)
(if so equipped)
5-100Starting and driving

The system is intended to assist the driver to
keep a following distance from the vehicle
ahead traveling in the same lane and direc-
tion.
The distance sensor is located behind the
front bumper
A. If the distance sensorA
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed to help
assist the driver to maintain a following dis-
tance.
The system automatically controls the
throttle and applies the brakes (up to 40% of
vehicle braking power) if necessary.
The detection range of the sensor is approxi-
mately 490 ft (150 m) ahead.
The distance sensor will not detect the fol-
lowing objects:∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane The display is located between the speedom-
eter and tachometer.
1. DCA system switch indicator: Indicates that the dynamic driver assis-
tance switch is on. 2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in
front of you.
WARNING
The DCA system automatically decelerates
your vehicle to help assist the driver to
maintain a following distance from the ve-
hicle ahead. Manually brake when decel-
eration is required to maintain a safe dis-
tance upon sudden braking by the vehicle
ahead or when a vehicle suddenly appears
in front of you. Always stay alert when us-
ing the DCA system.
