System limits
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.
