Low-Speed Deactivation If your speed falls below 25 mph (40 km/h) while following a vehicle ahead, Adaptive Cruise Control will begin to disengage. The driver alert symbol on the HUD will flash and the warning beep will sound. The driver must take action since Adaptive Cruise Control will not slow the vehicle to a stop. Passing a Vehicle/Adaptive Cruise Control Override To increase speed to pass a vehicle, use the accelerator pedal. While you are doing this, the system will not automatically apply the brakes. A PEDAL APPLIED ACC OVERRIDE message will appear on the HUD. See Head-Up Display (HUD) on page 3-43 for additional information. Once you pass the vehicle and remove your foot from the accelerator pedal, Adaptive Cruise Control returns to normal operation and the brakes can be applied, if needed.

A warning beep sounds and the message RADAR CRUISE NOT READY appears on the Driver Information Center (DIC). See DIC Warnings and Messages on page 3-79 for additional information. If Adaptive Cruise Control was braking when the HUD is turned off, the braking will continue briefly. { CAUTION: If you rest your foot on the accelerator pedal, the system will not automatically apply the brakes.
