UNDER CERTAIN ROAD AND DRIVING CONDITIONS, VEHICLE BODY ROLL AND ROAD INCLINATION CHARACTERISTICS MAY ADVERSELY AFFECT THE SLIP ANGLE CALCULATION OF THE ELECTRONIC STABILITY CONTROL (ESC) SYSTEM. THIS MIGHT CAUSE THE ESC TO PERCEIVE AN OVER STEERING SITUATION AND THEREFORE APPLY THE OUTER WHEEL BRAKE ON THE FRONT AXLE UNTIL THE VEHICLE IS PERCEIVED TO BE STABLE.

Risk: IF THE DRIVER IS SLOW TO REACT DURING THIS ESC INTERVENTION, THE VEHICLE MAY DEVIATE FROM THE INTENDED LINE OF TRAVEL, INCREASING THE RISK OF A CRASH.
