does it reduce the amount of care you need to take. As such, the driver must always
assume full responsibility for understandin g his/her surroundings, for operating the
steering wheel to correct the driving line, and for driving safely. Also, take occasional
rests from fatigue due to driving over long periods of time, etc.

cle is being driven without holding the steering wheel, a warning message is displayed.
