ESP is designed to reduce the risk of skidding by applying the brakes to the relevant wheel(s), and decreasing engine power, if it detects an over or understeer when cornering, an evasive maneuver or a sudden change in road conditions or traction. Note, it’s important to have any accessories i.e. a tow bar, fitted and programmed correctly. When a trailer or caravan is connected, the ESP is automatically configured to consider the additional weight load and distribution.
