2020 INFINITI QX60 sonar

The BCI system uses radar sensors1in-
stalled on both sides near the rear bumper to
detect an approaching vehicle and sonar sen-
sors
2to detect objects in the rear.
The radar sensors
1detect an approaching
vehicle from up to approximately 49 ft (15 m)
away. The sonar sensors
2detect stationary
objects behind the vehicle up to approxi-
mately 4.9 ft (1.5 m)
3. If the radar detects a vehicle approaching
from the side or the sonar detects close sta-
tionary objects behind the vehicle, the system
gives visual and audible warnings. If the driver
does not apply the brakes, the system auto-
matically applies the brake for a moment
when the vehicle is moving backwards. After
the automatic brake application, the driver
must depress the brake pedal to maintain
brake pressure. If the driver’s foot is on the
accelerator pedal, the system pushes the ac-
celerator upward before applying the brake.
If you continue to press the accelerator, the
system will not engage the brake.

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.

vehicle turns into your vehicle’s park-
ing lot aisle.
– Illustration
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.

SYSTEM MALFUNCTION
If the BCI system malfunctions, it will turn off
automatically, a chime will sound and the BCI
system warning light (orange) will illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine. If the warn-
ing light (orange) continues to illuminate,
have the system checked. It is recommended
that you visit an INFINITI retailer for this
service.
SYSTEM MAINTENANCE
The radar sensors1and the sonar sensors
2for the BCI system 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. Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors.
Do not strike or damage the area around the
radar sensors. It is recommended that you
visit an INFINITI retailer if the area around
the radar sensors is damaged due to a colli-
sion.

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:∙ The transmission is shifted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maximum
holding time is 2 seconds. After 2 sec-
onds the vehicle will begin to roll back and
the hill start assist system will stop oper-
ating completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
∙ The sonar system is not a replacement for
proper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. ∙ The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarm.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
∙ Keep the sonar sensors (located on the bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 sec-
onds when an obstacle is detected by only
the corner sensor and the distance does not
change. The tone will stop when the obstacle
get away from the vehicle. When the object is detected, the indicator
(green) appears and blinks and the tone
sounds intermittently. When the vehicle
moves closer to the object, the color of the
indicator turns yellow and the rate of the
blinking increases. When the vehicle is very
close to the object, the indicator stops blink-
ing and turns red, and the tone sounds con-
tinuously.
When the corner of the vehicle moves closer
to an object, the corner sonar indicator
A
appears. When the center of the vehicle
moves close to an object, the center sonar (if
so equipped) indicator
Bappears.
