the traffic situation. This could also cause
you to lose control of the vehicle. There is a
risk of an accident.
Only operate this equipment when the traffic
situation permits. If you cannot be sure of
this, stop the vehicle paying attention to
road and traffic conditions and operate the
equipment with the vehicle stationary.
Observe the legal requirements for the country
you are currently in while operating the on-

The on-board computer only shows messages
or warnings from certain systems in the dis-

vehicle is operating safely at all times. Other-
wise, you could cause an accident by driving
an unsafe vehicle. If your vehicle is not operat-
ing safely, stop immediately, paying attention
to the road and traffic conditions.
