Starting at a specific speed, this system alerts you when the vehicle on streets with lane markings is about to leave the lane. Depending on the country-specific version of the vehicle, the speed is between 35 mph/55 km/h and 45 mph/ 70 km/h. When switching on the system below this speed, a message appears in the instrument cluster.

The steering wheel begins vibrating gently in the event of warnings. The time of the warning may vary depending on the current driving situation.

The system does not provide a warning if the turn signal is set before leaving the lane.
