audio INFINITI QX55 2023 Repair Manual

–Snow chains are used.
– Wheels or tires other than INFINITI
recommended are used.
– The brakes are cold at low ambient
temperatures or immediately after
driving has started.
– The braking force becomes poor due
to wet brakes after driving through a
puddle or washing the vehicle.
• Turn the RAB system off in the following
conditions to prevent the occurrence of
an unexpected accident resulting from
sudden system operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed
truck.
– The vehicle is on the chassis
dynamometer.
– The vehicle drives on an uneven road
surface.
– Suspension parts other than those
designated as Genuine INFINITI
parts are used. (If the vehicle height
or the vehicle body inclination is
changed, the system may not detect
an obstacle correctly.) –
If the vehicle is using an accessory like
a bike rack, or cargo carrier that
blocks the sensors.
• Excessive noise (e.g., audio system vol-
ume, an open vehicle window) will inter-
fere with the chime sound, and it may not
be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “System
fault See Owner’s Manual” warning message
will appear in the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB system
checked. It is recommended that you visit an
INFINITI retailer for this service.
NOTE:
If the RAB system cannot be operated tem-
porarily, the RAB system warning light
blinks.
SYSTEM MAINTENANCE
Observe the following items to ensure proper
operation of the system:
• Always keep the parking sensors
O1clean.
• If the parking sensors are dirty, wipe them off with a soft cloth while being careful to
not damage them.
• Do not subject the area around the parking sensors
O1to strong impact. Also, do not
remove or disassemble the parking sensors.
If the parking sensors and peripheral areas
are deformed in an accident, etc., have the
sensors checked. It is recommended that
you visit an INFINITI retailer for this service.

•Read and understand the limitations of
the sonar system as contained in this
section. The colors of the sonar indicator
indicates different distances to the
object.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
• The sonar system is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
• The sonar system is not designed to pre-
vent contact with small or moving ob-
ject. Always move slowly. The system
will not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
• The sonar system may not detect the fol-
lowing objects: fluffy objects such as
snow, cloth, cotton, glass-wool, etc.;
thin objects such as rope, wire and chain,
etc.; or wedge-shaped objects.CAUTION
• Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
• The front and rear sonar detect the dis-
tance between the vehicle and the ob-
stacle by detecting the sound wave re-
flected from the surface of an obstacle.
When there is a sound such as horn, or an
ultrasonic source (such as sonar of other
vehicles) around the vehicle, the sonar
may not detect objects properly.
• Keep the sonar sensors (located on the
bumper fascia) free from snow, ice and
large accumulations of dirt. Do not clean
the sonar with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position. Sonar Operation Table

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
continuously.

ACTIVE NOISE CANCELLATION
This system uses microphonesO1located
inside the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.
NOTE:
To operate the active noise cancellation
system properly:
• Do not cover the speakers or woofer (if so equipped).
• Do not cover the microphones.
• Do not change or modify speakers includ- ing the woofer (if so equipped) and any
audio related components such as the
amplifier.
• Do not make any modification including sound deadening or modifications around
the microphones or speakers.
ACTIVE SOUND ENHANCEMENT
Active sound enhancement enhances exist-
ing engine sounds according to the engine
speed and driving modes through the speak-
ers and woofer (if so equipped).
