Important Information
Before using the backup sensors, make sure you read and understand the operation and limitations
of the system as discussed below and elsewhere in this manual.
• The backup sensors are designed to provide and audible sound when they detect large
stationary objects while the vehicle is moving in reverse at low speed. However, the system
may not detect all possible objects depending on their size, shape, or location.
• Even with the backup sensors, the driver is still responsible for making sure the path is clear
when operating the vehicle in reverse.

How the Backup Sensors Work
Backup Sensors
The sensors are ready for operation when the shift
lever is moved to the reverse position.
Operation of the sensors is dependent upon the
ultrasonic waves they emit. They calculate the
distance between the sensor and a rear obstacle by
measuring the time until the ultrasonic waves reach
the sensor after being reflected by the obstacle.
The sensors are designed to give you an audible
signal when the rear bumper of your vehicle is
approaching an obstacle.
•
The audible signal has three sounds:

How the Backup Sensors Work
Corner Sensors:
The sensors detect the closest
rear obstacle.
3710060M
The sensors may not detect the
rear bumper of tall vehicles.
3710070M
In this example, the corner
sensor detects the side wall.
Center Sensors:
3710050M

Limitations
The sensors detect only the closest obstacle. The
sensors may detect other obstacles as the vehicle
moves.
The sensors may not work if the obstacle is an odd
shape or made of material that does not reflect
ultrasonic waves.
Examples:
POLE
CARDBOARD
CARTON
SMALL or
SLENDER
TREE
TIRE of
BICYCLE
3710080M
RECTANGULAR
LUMBER
The sensors may not work if the ambient air
temperature is below -4°F (-20°C) or above 122°F
(50°C).
CURBSTONE

Limitations
The sensors may not sound for the following
obstacles or under the following conditions:
•
•
Objects that absorb ultrasonic waves, such as
soft snow, cotton and sponges
Piece of wire, rope, and net fence
3710120M
3710100M
•
Objects low in height such as curbstone, etc.
The audible signal may sound warning even if
there is no obstacle behind the vehicle:
•
Droplets of water frozen on the sensor
3710110M
3710130M

Limitations
The audible signal may sound warning even if
there is no obstacle behind the vehicle:
•
•
When the vehicle is equipped with a highpower radio and antenna
Sensors clogged with snow, dirt or mud
3710160M
3710140M
•
When detecting loud noises such as a vehicle
horn, a motorcycle’s engine, or air brakes
The sensors may sound continuously under the
following conditions:
•
When driving on rough surfaces or gravel
roads or in grass, or when stopped on a hill
3710170M
•
When driving in rain or melted snow
3710150M

Operation
Before using the backup sensors, become familiar
with the types of sounds in relation to the distances
between the sensors and the obstacle by actually
backing your vehicle into a garage or parking space.
Also confirm the obstacle detecting range of each
backup sensor.
1.
Check that the parking brake is applied.
2.
Turn the ignition switch ON (II). Do not start
the engine yet.
4.
From behind the vehicle, check that the
audible signal sounds by slowly bringing the
palm of your hand close to each sensor as
described:
For the corner sensors: From 2 feet
For the center sensors: From 6 feet
Confirm that the sound of the corner
sensors is different from that of the center
sensors.
ON
3.
Move the shift lever to reverse.
Confirm the obstacle
detecting range of
each sensor.

Operation
5.
Check that the intermittent warning beeps
become quicker as you bring the palm of
your hand closer to the sensor.
For the corner sensors: About 1.5 feet
For the center sensors: About 4 feet
6.
Check that the intermittent warning beeps
are changed to a continuous beep as you
bring the palm of your hand closer to the
sensor. The sensor may stop sounding or
sound intermittent beeps if you bring the
palm of your hand closer too quickly.
For the corner sensors: About 1 foot
For the center sensors: About 2 feet
7.
Turn the ignition switch to the LOCK “0”
position.

Daily Inspection
12
1.
Start the engine.
2.
Apply the parking brake, and depress the brake
pedal. Move the shift lever to the reverse
position. Check that the audible signal sounds
for about one second.
•
The sensors are normal if the audible signal
sounds for about one second.
•
If the audible signal keeps sounding, this is
an indication that the sensors are frozen or
clogged with mud, dirt, etc.
•
The sensors will also keep sounding when
there is an abnormality in the circuit.

Care of the Backup Sensors
Wipe the sensors clean with a clean cloth, or flush
with low-pressure water when the sensors are
clogged with mud and dirt.
Do not direct high-pressure water against the
sensors.

Troubleshooting
Perform the following checks if the audible signal
does not sound when the vehicle is approaching an
obstacle.
Symptom
Take your vehicle to your Acura dealer if you
encounter either of these problems:
•
The audible signal sounds continuously when
the shift lever is in the reverse position, and
the sensors are not frozen or clogged with
snow or mud.
•
The audible signal does not sound when the
shift lever is in the reverse position.
Remedy
• Clogged sensor
with snow or mud
• Wipe with clean cloth or flush
with low-pressure water.
• Frozen sensor
• Melt with lukewarm water
• Extended parking
in cold weather or
under blazing sun
• The backup sensors may not
work if the outside air
temperature is below -4°F
(-20°C) or above 122°F (50°C).
Ask your Acura dealer for advice if the trouble
persists.

Troubleshooting
Troubleshooting With Beeps
Corner Sensors
Series of two intermittent beeps: right sensor is faulty.
Series of three intermittent beeps: left sensor is
faulty.
Series of four intermittent beeps: right and left
sensors are faulty.
Center Sensors
Series of three beeps: either or both sensors are
faulty.
Be careful not to confuse the sound of the sensors
with those of other components or systems.
