ESP is the abbreviation for “Electronic stability programme”. The system's task is to assist the driver in demanding driving situations, e.g. if a wild animal suddenly runs across path of vehicle, and also to compensate for overreaction on the part of the driver and to prevent loss of vehicle stability. However, ESP is not intended for speed manics to try and defy the laws of physics.
A responsible driving style adapted to the prevailing road and traffic conditions is therefore still essential. In the course of this booklet, we will explain how ESP is based on the proven anti-lock braking system (ABS) and its related systems - TCS, EDL, EBD and EBC - and we will describe the various versions of ESP which we use in our vehicles.
