Hill Start Assist

WARNING: This page is about a different car, the 2009 Dodge Avenger and 2009 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The Hill Start Assist (HSA) system, programmed into the ESP system, is designed to assist the driver when starting a vehicle from a stop on a hill. HSA will maintain the level of brake pressure the driver applied for a short period of time after the driver takes his foot off of the brake pedal. If the driver does not apply the throttle during this short period of time the system will release brake pressure and the vehicle may roll down the hill. The system will release brake pressure in proportion to the amount of throttle applied as the vehicle starts to move in the intended direction of travel.
