For example: R
ad iverted route R
the road layout or the direction of ao ne-way
street has been changed
For this reason, you must alway so bserve road
and traffic rule sa nd regulations during your
journey. Roa da nd traffic rule sa nd regulations

Please alway su se this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
