you to divert your attention from driving and
increase the risk of an accident.

Route guidance in these areas
When you are
entering a partially digitized area
or
starting route guidance within such an
area,
the navigation system will inform you that
turn by turn guidance cannot be provided
with corresponding navigation displays
and voice announcements.Map display
Within these areas the display shows a
split screen with the map on the left-hand
side and a direction arrow on the right side
pointing to the destination instead of the
symbol for the next driving maneuver
(page 174).
Route presentation
Usually the map highlights the active route
on verified roads with a blue line.
After route calculation, the route may
contain unverified road sections. Here, the
exact route guidance is suppressed and
these route sections will appear as blue
dotted lines. This type of line e.g. connects
two verified road sections, which are
displayed as blue lines or connects the end
of a verified road with a stopover or
destination located on an unverified road.
i
Displayed or audible distance to the
beginning of such an area is an
estimation. The actual distance may
differ.
WarningG
If the origin and destination are located very
close to each other, the system may not pro-
vide the shortest path to the destination
when you are travelling in an unverified area.
In most cases you will be directed to a veri-
fied road closest to the destination. This
may appear to be a long and inconvenient
route but it is safer. At your own risk, you
may choose to drive on the unverified roads
to the destination.

Destinations and stopovers located in
unverified roads are entered in exactly
the same way as they are in verified

page 152) or a
stopover (
page 182).

Route guidance
OFF ROADIf there is no road shown on map at the
current position, the vehicle is OFF ROAD.
COMAND is able to guide you to an OFF
ROAD destination or from an OFF ROAD
location.
COMAND will inform you with the
OFF
ROAD
indication and the direction arrow
pointing to the destination. Corresponding
announcements may be audible.

OFF ROAD indication
As soon as the vehicle is back on a road
known to the system, route guidance
continues in the usual way.
WarningG
The COMAND navigation system may direct
you to off-road routes that your vehicle may
not be capable of traversing through without
damaging your tires, wheels or vehicle. It is
the driver's sole responsibility to determine
the suitability of the route. Off-road routes
may be of varying conditions and their ap-
propriateness for use may be affected by
various factors such as time of day, time of
year and immediate weather conditions that
cannot be judged or taken into consider-
ation by the COMAND system.
i
An OFF ROAD destination is not itself
recorded on the map. You can enter an
OFF ROAD destination using the map,
for example (
page 161).
