Route guidance
Route guidance to an off-road destina-
tion
COMAND can guide you to destinations
within the area covered by the digital map,
even if a destination is not located at a
road known to the system.
These destinations are shown as off-road
destinations, which you can enter using
the map, for example.
In these cases, COMAND guides you for as
long as possible with navigation announce-
ments and displays on roads known to the
system.
Shortly before you reach the last known
point in the digitized road network, you will
hear the announcement “The destination
is nearby. Follow the arrow on the display”.
You will then see an arrow that indicates
the direction to the off-road destination.
When the off-road destination is close to
the road, “Area of dest. reached” appears
in addition below the arrow. The section of the route from the last
known point on the map to the off-road
destination is highlighted blue. It simply
shows the direction to the off-road
destination without taking into account
any type of obstacles in the way.

WarningG
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of trav ersing through without
damaging your tires, wheels or vehicle. It is
the driver's sole responsibility to determine
the suitability of the ro ute. Off-road routes
may be of varying cond itions and their ap-
propriateness for use may be affected by va-
rious factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into considerati-
on by the COMAND system.
