REVERSING RADAR SYSTEM

GENERAL INFORMATION

Description

Operation

Reversing radar system is an auxiliary system intended to assist driver when reversing, consists of reversing 
radar sensor (probe), reversing radar control module assembly and alarm device (instrument cluster built-in 
buzzer). Reversing radar system is activated when shift lever is shifted to reverse range. When the reversing 
radar sensor detects obstacles behind, the instrument cluster built-in buzzer will sound. This can help driver to 
eliminate the blind corner and blurred vision, thus improving the driving safety when reversing.

Reversing Radar Normal Alarm Display

Reversing radar system consists of four reversing radar sensors and one reversing radar control module 
assembly.
It is activated when the shift lever is shifted to R and reversing at the speed below 5 km/h with ignition switch 
ON. The corresponding measured message will be displayed on multi-information display and alarm with 
buzzer in instrument cluster.
The response way of reversing radar system is buzzer response. The table below shows the correspondence 
between buzzer response frequency and actual obstacle distance:
