Congratulation on your purchase of the HAWK HRA-5300 D/R back up sensor, designed to aid
operation when backing up your vehicle. Please read carefully before using and understand the
features and limitations of this product, keep this manual in the glove compartment. This manual
contains important information on safety operations of the backup sensors, it is important that you get
familiarized with all functions and descriptions, and follow the recommendations listed so you can
make your experience safer and enjoyable.
The system
The sensors activate automatically when vehicle gear is in reverse position (vehicle ignition must be
ON in order for the system to operate.)
Sensors are designed to provide a warning when it detects an object as the vehicle is backing up
(reverse) at slow speed. You must be aware that the sensors may not detect some objects depending
on the size, shape, material or position. Remember that even with backup sensors the driver is
responsible for the path to be clear when backing up (when operating vehicle in reverse).
Warning: Improper use of the backup sensor could result in injury or death! This back up sensor
is strictly a drive assist device. It is not a substitute of driverʼs responsibilities when backing up
the vehicle. Please drive carefully and follow all local and EU laws when backing up your vehicle.
Commercial Electronics does not guarantee or assume any liability for injuries or damage that occurs

Introduction
2
How it works
The functions of the sensors depend on an ultrasonic signal that is transmitted by them. They
calculate the distance between the object and the sensor by measuring the time it takes for the waves
to return after reflecting on the object. This system is designed to give you a visual and auditory
signal when the rear bumper of your car is getting close to an object.
3
Limitations
The system could malfunction at theses temperatures: below -22 Fahrenheit (-30 Celsius) or above
176 Fahrenheit (80 Celsius).
The sensors may not work if an object does not reflect the ultrasonic waves or it has an unusual
shape, pole cardboard carton, tire of bicycle, small or slender tree, rectangular lumber or curbs tone.
The sensor may not detect another vehicle bumper if itʼs too high.
Also note: This system has different detection distance to the different object. To the wall, the max
detection distance is 1.8m; to the human body, the max detection distance is 1.0m; to the column �
40cm, the max detection distance is 1.2m.
How to test
Warning: Do not stand behind a moving vehicle death or injury could occur.
Apply the hand brake.
Turn ignition on (Do not start the vehicle)
Place the shift gear to reverse position.
From behind the vehicle proceed to check the system by placing the palm of your hand slowly back
and forth in front of each sensor. Note: make sure you check all of them.
Note: the distance displayed on the screen is approximate.

Maintenance
Always keep sensor from dirt, snow and mud, clean them with a soft towel and low pressure water.
Self-Test function
The back-up system only activates when the vehicle is placed in reverse gear. When placed in
reverse gear the system first does a diagnostic check to ensure the system is fully functional and
reports any sensor malfunctions within the back- up system. If there is any malfunction with the
sensors, the LED display (optional) will show following error message and buzzer will sound.
Number 1 displayed means sensor number 1 is faulty and buzzer will sound once
Number 2 displayed means sensor number 2 is faulty and buzzer will sound twice.
Number 3 displayed means sensor number 3 is faulty and buzzer will sound 3 times.
Number 4 displayed means sensor number 4 is faulty and buzzer will sound 4 times.

Installation Instruction
Note: Before installing system let the components of the exhaust system cool
down. This will make the installation safer and preclude heat damage to the backup sensor wiring or
components.
