Approach warning

When your vehicle is too close to a vehicle ahead, and sufficient
automatic deceleration via the cruise control is not possible, the dis-
play will flash and the buzzer will sound to alert the driver. An
example of this would be if another driver cuts in front of you while
you are following a vehicle. Apply the brakes to ensure an appro-
priate vehicle-to-vehicle distance.

will not occur:

When the speed of the vehicle ahead matches or exceeds your
vehicle speed

speed
