Panic Assist Braking
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Using a specially developed pressure/pedal movement mechanism, the panic assist braking functions by fully applying the brakes during a panic stop. Depending on the vehicle speed, if a pedal stroke is more rapid than normal, the brake booster automatically applies full brake boost. Panic assist is disabled when the driver releases the brake pedal.
