Important safety notes

WARNING
Operating the integrated information systems
and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.

attention to the traffic conditions and consult
a qualified specialist workshop.
