Toyota Corolla: Dynamic radar cruise control with full-speed range / Approach warning (vehicle- to-vehicle distance control mode)
When your vehicle is too close to a vehicle ahead, and sufficient automatic deceleration
via the cruise control is not possible, the display 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. Depress the brake pedal to ensure
an appropriate vehicle-to-vehicle distance.
