If a lurching motion is detected, the trailer stabilisation function automatically helps to reduce the
trailer's rocking motion using counter steering assistance.
Requirements for trailer stabilisation
• The vehicle is a factory-fitted towing bracket or a compatible towing bracket is fitted.
• Electronic Stability Control and the traction control system (TCS) are active. The indicator lamp
or
in the instrument cluster is not lit up.
• The trailer is electrically connected to the towing vehicle via the trailer socket.
• The vehicle speed is higher than approximately 60 km/h (37 mph).

Introduction
Do not let the extra safety afforded by the trailer stabilisation function tempt you into
taking any risks when driving – this can cause accidents.
• Always adapt your speed and driving style to suit visibility, weather, road and traffic
conditions.
• Accelerate carefully on slippery surfaces.
• Take your foot off the accelerator if one of the systems is active.
WARNING
The trailer stabilisation function may not be able to detect all driving situations correctly.
• Trailer stabilisation is switched off when ESC is deactivated.
• Light trailers that are snaking will not be recognised by the trailer stabilisation function
and stabilised accordingly in all cases.
• A trailer can still
jack-knife
on slippery roads with little grip, even if the towing vehicle
is equipped with trailer stabilisation.
• Trailers with a high centre of gravity might tip over before snaking starts.
• Sudden braking procedures could occur automatically in extreme driving situations if
the trailer socket is being used without a trailer (e.g. for a bicycle carrier with lighting).
