SAFETY INSTRUCTIONS
Use of the Navigation System is only permitted 
if the traffic conditions are suitable and you 
are absolutely sure that no risk, obstruction 
or inconvenience will be incurred to you, 
your passengers or other road users. The 
requirements of the Road Traffic Regulations 
must always be followed. The destination 
must not be entered while driving the car.
The Navigation System serves solely as an 
aid to navigation. It never releases the driver 
from his duties to drive carefully and to make 
own judgement in road traffic. Inaccurate 
or incorrect instructions may happen to be 
given due to changing traffic conditions. The 
actual road signs and traffic regulations must 
therefore always be observed. In particular, the 
Navigation System cannot be used as an aid to 
orientation when visibility is poor.
This Navigation System must only be used for 
its intended purpose. The volume of the car 
radio/Navigation System must be adjusted so 
that external noise is still audible.
