Trailer Stability Control (Trailer Sway Control)
Trailer stability control detects when a trailer starts to sway and brakes the car to bring the combination back under control.
What is Trailer Stability Control (Trailer Sway Control)?
It is a function of the car's electronic stability control. It usually works only when the car recognises that a trailer is connected. It reduces speed by braking and cutting engine power. If sway starts, the driver should ease off the accelerator and hold the wheel steady rather than braking hard or steering sharply, unless the system or situation requires braking.
How it works
Sensors detect the rhythmic yawing motion that sway causes, and the system brakes individual wheels.
Why it matters for your car
It cannot make up for a badly loaded trailer or excessive speed. Correct nose weight and tyre pressures on both car and trailer remain essential.
