The trailer stabilization control in your BMW is a safety system and helps you to absorb swinging of the trailer. Swinging is detected by the system and your BMW automatically brakes quickly. This way, the critical speed range is left and the vehicle-trailer combination is stabilized. If the trailer power socket is occupied but a trailer has not been hitched, this system can also activate in extreme driving situations, e.g., when using a rear bicycle rack with lighting.
Functional requirement
- A trailer is attached.
- The trailer power socket is occupied.
- Vehicle speed must be more than approx. 40 mph/65 km/h.
System limits
The system cannot intervene or not intervene in time in the following situations, for instance:
- If a trailer jackknifes suddenly, for instance on slippery roads or loose surfaces.
- If a trailer with a high center of gravity tilts, before swinging is detected.
- If Dynamic Stability Control is deactivated or has malfunctioned.
- When the power consumption of a trailer is too low, for instance due to tail lights with LED technology, to be detected by the system.
