Panic Assist Braking
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
Panic assist braking functions by fully applying the brakes during a panic stop, using a specially developed pressure/pedal movement mechanism. Depending on vehicle speed, if pedal stroke is more rapid than normal, the brake booster automatically applies full brake boost. Panic assist will be disabled when the driver releases the brake pedal.
