344
ANSWER
The route settings may conflict with the current location (exclusion
of toll roads on a toll motorway).
The POIs have not been selected.
The audible warning is not active.
The guidance criteria do not take account of TMC messages.
Other than guidance, the system announces all Hazard zones
positioned in a cone located in front of the vehicle. It may provide
an alert for a Hazard zone located on nearby or parallel roads.
SOLUTION
Check the route settings in the "Navigation"
menu.
Select the POIs in the list of POIs.
Activate audible warnings in the "Navigation"
menu.
Select the "Traffic info" function in the list of route
settings.
Zoom in on the map to view the exact position of the
Accident-prone area. Select "On the route" to no
longer receive alerts other than navigation instructions
or to reduce the time for the announcement.
