System limits

The system cannot serve as a substitute Personal responsibility

The system cannot serve as a substitute for the driver's personal judgment of the traffic situation.

In the event of a warning, do not jerk the steering wheel, as you may lose control over the vehicle.

The system may not be fully functional in the following situations:

  • When a vehicle is approaching at a speed much faster than your own.
  • In heavy fog, rain or snowfall.
  • In tight curves or on narrow lanes.
