Description of On-Board Diagnostics: Overview

The Electronic Stabilization Program (ESP) is designed to stabilize the dynamic handling response of the vehicle by counteracting any tendency toward oversteer or understeer.

ESP is an expanded version of the existing on-board safety systems ABS/EDL and ABS/EDL/ASR.

ESP enhances the degree of control in critical dynamic conditions, i.e. when the driver approaches the handling limits of the vehicle. Compared with the existing safety systems, ESP further reduces the risk of skidding and improves handling.

However, ESP is not able to overcome the physical limits of the available road adhesion.
