ditions. You could then lose control of the
vehicle. Ther eisarisk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pullo ver toasafe
location and make entries only while the vehi-

The navigation system calculates the route to
the destination without taking account of the
following, for example:
R traffic lights
R stop and give way signs
R parking or stopping restrictions
R road narrowing
R other road and traffic rule sand regulations
The multimedi asystem may provid eincorrect

do not correspond to the data on the digital map (for example, aroute may have been diverted or
the direction of aone-wa ystreet may have
changed).
For this reason, you must alwayso bserve road
