assist, all wheels are used in tandem to brake
the vehicle combination and the electric motor's
drive is reduced. When fishtailing has gradually
been eliminated and the combination is stable
again, the system stops exerting control and the
driver regains full control over the car.
Trailer Stability Assist may not intervene if the
driver attempts to stop the car fishtailing by
means of violent steering wheel movements, as
the system is then unable to determine whether
the trailer or the driver is causing the fishtailing.
When Trailer Stability Assist is
operational, the ESC symbol in
the driver display flashes.
