PRE-COLLISION SYSTEM

CONSTRUCTION

OPERATION

1. Pre-collision System Operation Status Display

   
   

   1. When the driving support ECU assembly, which controls the pre-collision system determines that there is a high possibility of a collision, the driving support ECU assembly sends a display request signal to the combination meter assembly in order to display a warning message on the multi-information display and headup display* and intermittently sounds the pre-collision city buzzer at the same time, alerting the driver.

2. Indicator Display when Pre-collision System Off

   
   

   1. When the pre-collision system is set to off via the setting screen on the multi-information display, the PCS warning light in the combination meter assembly illuminates and a message is displayed on the multi-information display.

   2. When the pre-collision brake assist and pre-collision braking cannot be activated due to VSC OFF switch operation, the VSC OFF indicator light and PCS warning light in the combination meter assembly illuminate and a message is displayed on the multi-information display.

3. Pre-collision System Warning Display

   
   

   1. When the driving support ECU assembly detects a system malfunction or temporary non-activation, the driving support ECU assembly sends a warning display request signal to the combination meter assembly to illuminate the PCS warning light and displays a message on the multi-information display. Also, when the driving support ECU assembly determines that the malfunction occurs due to a failure, the driving support ECU assembly illuminates the master warning light and sounds the buzzer (built into combination meter assembly).
