Volkswagen Touran Owners Manual: Function
Fig. 155 Windscreen: Lane Assist camera window
First read and observe the introductory information
and safety warnings 
Using a camera in the windscreen, the lane departure warning system detects possible marking lines on the road lane. If your vehicle approaches a recognised marking line unintentionally, the system will warn the driver with a corrected steering intervention. The corrective steering intervention can be overridden by the driver at any time.
No warning will be given if the turn signal is switched on as the lane departure warning system will presume the lane change is deliberate.
Steering wheel vibration
The following situations will cause the steering wheel to vibrate and demand active steering intervention by the driver:
- If the maximum steering moment in corrective steering intervention is not sufficient to keep the vehicle in the lane.
- If a lane is no longer detected by the system during the corrective steering intervention.
Switching the lane departure warning system on and off manually
- Using the button for driver assist systems, select the corresponding menu option   .
- OR: in the menu Settings sub-menu Assistant, activate or deactivate the system using Lane Assist   . A tick indicates when a driver assist system is switched on.
Automatic switch-off: The lane departure warning system can switch itself off automatically if there is a system malfunction. The indicator lamp goes out.
Lane departure warning system is not active (the indicator light lights up yellow)
- If the vehicle speed is less than approx. 65 km/h (40 mph).
- If the lane departure warning system cannot detect the markings on the lane the vehicle is in. For example due to road works or in snow, dirt, wet weather or oncoming lights.
- The radius of a bend is too small.
- If there is no lane marking.
- If the nearest lane marking is too far away.
- If more than two lane markings are used per lane.
- If the TCS is switched off.
- If the system does not detect any clear steering activity by the driver over an extended period.
