The concept
This system issues a warning at speeds above approx. 40 mph/65 km/h if the vehicle is about to leave the lane on roads with lane markings.
The steering wheel begins vibrating gently. 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.
