Collision Warning and Collision Avoidance System - System Operation and Component Description: Overview

The forward collision warning system works in conjunction with the ACC system. The forward collision warning system provides two major alerts for the driver in the event of a collision. A red warning indicator from the HUD module and an audible warning chime from the IPC. For this system, a HUD with driver information display is controlled by the IPC and illuminates a solid red bar that appears on the windshield in place of any other selected indicators. For additional information about the HUD, Refer to: WARNING CHIMES .

If the system senses the driver is not reacting, the CCM sends a message to the ABS module to charge the brakes for more sensitive braking or for automatic braking to slow or stop the vehicle to avoid or reduce the impact of a collision.
