♦ When vehicle runs forward, rear sensors never work, but after
each brake, the front sensors work for 10s, and report the
obstacles only if they are located in the display distance.

♦ Audible warning of diagnostics
When some sensor is found defective during diagnostics, the
system will tell you its serial number by beeping discontinuously
as per Diagram 4. But system continuously beeps for 1.5
seconds, if all sensors are defective.
Ex. 1: in case sensor No. 3 is abnormal
No.4. When you re-start the system, after the beep of 0.5 second, system
rapidly beeps 6 times.
Once some sensor is found abnormal, "EX" will be displayed for
less than 3 seconds, "X" is the serial number (1~8) of the
abnormal sensor
Ex 1: If "EH" is displayed, it tells you the sensor No. 4 doesn't work.
Ex 2: If neither sensor No. 4 nor No. 6 works, "EH" and "E6" will appear in
the display successively.
If none of the sensors works, "EE" will be displayed, and the
system beeps continuously for 1.5 seconds.

• Determine where to install sensors.
• Remove the protective layer of sensor's adhesive tape, and
stick sensors tightly on trunk lid in right direction.
• Avoid any impact to the sensors within 48 hours after
installation.
• Never pull sensor cables with too much force, because you
may damage the connection between sensor and its cable.
