Hydraulic Brake Assist
WARNING: This page is about a different car, the 2009 Dodge Caliber. However, it is still accessible from the selected car via links, so may be relevant.
Brake Assist is programmed into the ESP® system. Brake assist helps the driver overcome the tendency to not apply the brakes hard enough or quick enough to achieve the minimum stopping distance during a panic stop. During this situation, the ESP® system instantly applies the maximum available pressure to the brakes and the vehicle stops as quickly as available traction will allow.
