sensor INFINITI QX50 2019 Workshop Manual

If the radar detects an approaching vehicle
from the side, the system chimes a sound
(single beep), the side indicator light on the
side of the approaching vehicle flashes and a
yellow rectangular frame appears in the dis-
play
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 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.
After the automatic brake application, the
driver must depress the brake pedal to main-
tain brake pressure.

BCI SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the BCI system. Failure to follow the warn-
ings and instructions for proper use of the
BCI system could result in serious injury or
death.
∙ The BCI system cannot detect all vehiclesunder all conditions.
∙ Always check surroundings and turn to check 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 15 mph
(24 km/h)
∙ 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.

– IllustrationC: 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 approach-
ing vehicle is small.
∙ The radar sensors are designed to ignore most stationary objects; however, ob-
jects such as guardrails, walls, foliage and
parked vehicles may occasionally be de-
tected. This is a normal operation
condition.
∙ 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.

RCTA SYSTEM LIMITATIONS
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.

(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 19 mph
(30 km/h)
– A vehicle that is passing at speeds lower than approximately 5 mph
(8 km/h)
∙ The radar sensors may not detect ap- proaching vehicles in certain situations:
– Illustration

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the system
will be deactivated automatically. The “Un-
available: Side Radar Obstruction” warning
message will appear and the
BSI/BSW/BCI/RCTA indicator (white) will
blink
Ain the vehicle information display.
The systems are not available until the condi-
tions no longer exist.
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
BSI/BSW/BCI/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.

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.
