c)
With chalk or marker, mark the position of sensors on the rear bumper. Make sure that the sensors can be
pushed all the way in and that you can feed the wires through.
d)
Drill the holes through the bumper at the marks with the
Φ
22.3mm drill bit included.
Note:
if drilling through
metal bumper, you will need a bi-metal
Φ
22.3mm (7/8") drill bit (not included).
e)
If necessary, smooth the sharp edge of the holes with a polishing head or small round file.
f)
Run the sensor wires into the holes drilled. Push the sensors into the holes.
Note:
When pushing in the
sensors only apply pressure at the edges, not on the middle of the sensor to avoid damage to the sensor
element. The sensors are tapered for a snug fit.
g)
Adjust the sensors for non-vertical bumper surface by rotating the sensors themselves (Fig.2). The sensors
are made with wedge-shaped edge for this purpose.
h)
Run the sensor wires from the bumper into the trunk or inside of the vehicle through the existing small vent
or rubber grommet in the rear of the trunk or vehicle, and to the main control box.
Note:
Do not cut the
sensors wires.
i)
Attach sensor wires to the vehicle body with cable/wire ties so that they will not get in the way of any moving
parts and there are no loose wires hanging down.
j)
Plug one sensor at a time into its corresponding socket at the main control box, start the engine and put the
vehicle in reverse, the display should show the correct obstacle distance. Repeat the procedure for the
remaining sensors.
Note:
When you shift into reverse gear, the system will beep once indicating it is
activated.
Testing Your New Backup Parking Sensor System
Back your vehicle slowly (about 3 miles per hour) to approximately 2.5m (8.2 feet) from a flat vertical surface
such as a wall. Continue to back up slowly and check the performance against Chart 1.
Using the Wireless Digital Display
The display has a built-in beeper (audible alert). There are seven (7) LED Lights (Green/Yellow/Red) on each
side of the two-digit distance display (Fig. 4). The color LED lights have two functions: indicating the orientation of
obstacle and showing if you are in Safe/Warning/Stop zone (Chart. 1).
