ESP® trailer stabilization
If your vehicle with trailer (vehicle/trailer combination) begins to lurch, you can only stabilize the vehicle/trailer combination by depressing the brake firmly.
In this situation, ESP® assists you and can detect if the vehicle/trailer combination begins to lurch. ESP® slows the vehicle down by braking and limiting the engine output until the vehicle/trailer combination has stabilized.
Trailer stabilization is active from a speed of approximately 40 mph(65 km/h).
WARNING 
The system will not be able to assist when the
trailer jackknifes
• if the ESP® has switched off due to
a
malfunction
• on wet or icy roads
• on roads with slippery surface
• in sand or gravel
Trailers with a high center of gravity may tip
over before the system recognizes swaying of
the trailer.
Trailer stabilization does not work if ESP® is deactivated or disengaged because of a malfunction
