Hydraulic Brake Assist
WARNING: This page is about a different car, the 2009 Jeep Patriot and 2009 Jeep Compass. 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.
