BMW X5: Steering Assistant

Principle

The Steering Assistant helps keep the vehicle in the lane. For this purpose, the system executes supporting steering movements, for instance when driving in a curve.

General information

Depending on the speed, the system orients itself according to the lane markings or vehicles in front.

Sensors on the steering wheel detect whether the steering wheel is being touched.

Safety information

Warning

The system cannot serve as a substitute for the driver's personal judgment in assessing the traffic situation. Based on the limits of the system, it cannot independently react to all traffic situations. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.
