THE BACK-UP COLLISION
INTERVENTION (BCI) SYSTEM (if so
equipped)
WARNING
● The BCI system is not a replacement for
proper driving procedure, is not de-
signed to prevent contact with vehicles
or objects and does not provide full
brake power. When backing out of park-
ing space, always use the side and rear
mirrors and turn and look in the direc-
tion you will move. Never rely solely on
the BCI system. ●
There is a limitation to the detection
capability of the radar or the sonar. Us-
ing the BCI systems under some road,
ground, lane marker, traffic or weather
conditions could lead to improper sys-
tem operation. Always rely on your own
operation to avoid accidents.
BCI SYSTEM DESCRIPTION
The BCI systems can help alert the driver of an
approaching vehicle or objects behind the ve-
hicle when the driver is backing out of a parking
space.
When the shift position is R (Reverse) and the
vehicle speed is less than approximately 5 MPH
(8 km/h), the BCI system operates.

Page 402 of 577

The BCI system uses radar sensors1installed
on both sides near the rear bumper to detect an
approaching vehicle and sonar sensors to 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 approximately
4.9 ft (1.5 m)
3. If the radar detects a vehicle approaching from
the side or the sonar detects close stationary
objects behind the vehicle, the system gives vi-
sual and audible warnings. If the driver does not
apply the brakes, the system automatically ap-
plies 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 accelerator upward before applying
the brake. If you continue to press the accelera-
tor, the system will not engage the brake.

BCI system precautions
WARNING
●Always check surroundings and turn to
check what is behind you before back-
ing up. The radar sensors detect ap-
proaching (moving) vehicles. The radar
sensors cannot detect every object such
as:
– Pedestrians, bicycles, motorcycles, animals or child operated toy
vehicles
– A vehicle that 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.
– Illustration C: When the vehicle is parked on inclined ground.

Page 404 of 577

– Illustration D: When an approachingvehicle turns into your vehicle’s park-
ing lot aisle.
– Illustration E: When the angle formed by your vehicle and ap-
proaching vehicle is small
● The following conditions may reduce
the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice build up on the vehicle
– Frost up on the vehicle
– Dirt up on the vehicle
● Do not attach stickers (including trans-
parent material) , install accessories or
apply additional paint near the radar
sensors. 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 sen-
sor may not detect:
– Small or moving objects
– Wedge-shaped objects – Object 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 sys-
tem is not as effective on a slope as it is
on flat ground. When on a steep slope
the system may not function properly.
● Do not use the BCI system under the
following conditions because the sys-
tem may not function properly.
– When driving with a tire that is not within normal tire conditions (e.g.
tire wear, low tire pressure, installa-
tion 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 systems when tow-
ing a trailer.
● Excessive noise (e.g. audio system vol-
ume, open vehicle window) will inter-
fere with the chime sound, and it may
not be heard. When the shift lever is placed in R (Reverse)
position, the BCI ON appears in the vehicle infor-
mation display.

If the radar detects an approaching vehicle from
the side, the system chimes a sound (single
beep) , the Blind Spot Warning indicator light on
the side of the approaching vehicle flashes and a
yellow rectangular frame appears in display “A”.NOTE:
● In the case of several vehicles approaching
in a row (Illustration 1) or in the opposite
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 a
object behind the vehicle has a higher prior-
ity than the BCI chime (single beep) indicat-
ing an approaching vehicle. If the sonar sys-
tem detects an object behind the vehicle
and the BCI system detects an approaching
vehicle at the same time the following indi-
cations are provided:
– The sonar system chime sounds
–
The Blind Spot Warning indicator light on
the side of the approaching vehicle flashes
and

– A yellow rectangular frame appears indisplay.
If an approaching vehicle or object behind the
vehicle is detected when your vehicle is backing
up, a red frame will appear in the display Aand
the system will chime 3 times. Then, the brakes
will be applied momentarily. 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 moves the accelerator pedal upward be-
fore the braking is applied. However, if you con-
tinue to accelerate, the system will not engage
the brakes.
NOTE:
The system does not operate if the object is
very close to the bumper.The BCI system automatically turns on every time
the engine is started.
The BCI system can be turned off temporarily by
pushing the BCI switch. The BCI OFF display
appears on the vehicle information display. When
the shift lever is placed into the R (Reverse)
position again, the BCI system is turned on.
The BCI system can be turned off permanently by
setting in the vehicle information display.
1. Press the
button until “Settings” dis-
plays in the vehicle information display. Use
the
button to select “Driver Assis-
tance”. Then press the ENTER button.

2. Select “Back-up Collision Interv.”, and pressthe ENTER button.
3. To set the BCI system to on or off, use the buttons to navigate in the menu and use the
ENTER button to select or change an item.
BCI temporarily not available
If the following messages appear on the vehicle
information display, a chime will sound and the
BCI system will be turned off automatically.
● “Unavailable High Accelerator Temp. ” :
If the vehicle is parked in direct sunlight
under high temperature conditions (over ap-
proximately 104°F (40°C) and then started,
the BCI system may be deactivated auto-
matically and the “Unavailable High Accel-
erator Temp” message will appear in the
vehicle information display for a period of
time.
When the interior temperature is reduced,
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. BCI 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 warning light
(orange) continues to illuminate, have the system
checked by an INFINITI retailer.

RADAR MAINTENANCE
The two radar sensors1for the BSW, BSI and
BCI systems are located near the rear bumper.
Always keep the area near the radar sensors
clean.
The radar sensors may be blocked by temporary
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 ma-
terial) , install accessories or apply additional
paint near the radar sensors.
Do not strike or damage the area around the
radar sensors. Consult an INFINITI retailer if the
area around the radar sensors is damaged due to
a collision.
