Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Trailer Stability Control
The trailer stabilization control detects seesaw motion of a trailer around the vertical axis. The system works as of a speed of approx. 65 kph with the electrical connector for trailer occupied. The dynamic stability control (DSC) monitors the yawing motion of the vehicle with the help of the DSC sensors. If the limit value is exceeded on the swinging trailer, the engine output is reduced. The DSC also automatically brakes all 4 wheels. With disabled or defective DSC, the trailer stabilization control is also disabled.
