Collision Mitigation System (CMS)
The CMS provides the driver with audible and visual alerts when the vehicle's following distance could result in a rear-end collision. The OnGuard display unit shows a graphic of the condition, enhanced by a screen color relevant to the intensity of the situation. See Table.. If a potential rear-end collision is imminent, OnGuard's active braking automatically applies the engine and service brakes to slow the vehicle. The active braking application is intended only to provide early braking; the driver is still required to recognize and react to all driving situations.
Important: CMS and active braking are not operational at vehicle speeds below 15 mph (25 km/h).

Standby
When no lead vehicle is detected, the display shows that the CMS is on and the radar is searching. See Fig..
Fig. 1, CMS Standby (blue)
A Vehicle is Detected
When a lead vehicle is detected in the lane ahead, the display shows that the CMS is on and the radar is tracking a lead vehicle at the speed shown. See Fig..
If the following distance between the vehicle and the lead vehicle is too close, the CMS will emit an audible alert and the display background will turn yellow. The alert will end when the vehicle speed drops below the lead vehicle speed and the following distance is increased.

Collision Warning
When a lead vehicle is detected traveling slower than your vehicle, or the gap between them becomes too close, the CMS warns of an impending collision by emitting an urgent audible alert and displaying the collision warning symbol with a red background. See Fig..
