Route guidance
General notesGWARNING
COMAND calculates the route to the
destination without taking into account the
following, for example:
R Traffic lights
R Stop and right-of-way signs
R Lane merging
R Parking or stopping prohibited areas
R Other road and traffic rules and regulations
R Narrow bridges
COMAND may give incorrect navigation
commands if the data in the digital map does
not correspond with the actual road/ traffic
situation. For example, if the traffic routing
has been changed or the direction of a one-
way road has been reversed.
For this reason, you must always observe
applicable road and traffic rules and
regulations during your journey. Road and
traffic rules and regulations always have
priority over the navigation commands
generated by the system.
Route guidance begins once a route has been
calculated ( Y page 156).
COMAND guides you to your destination by
means of navigation commands in the form
of audible navigation announcements and
route guidance displays.
The route guidance displays can only be seen
if the display is switched to navigation mode.
If you do not follow the navigation
announcements or if you leave the calculated
route, COMAND automatically calculates a
new route to the destination.
If the digital map contains the corresponding
information, the following applies:
R when selecting a route, COMAND tries to
avoid roads that only have limited access,
e.g. roads closed to through traffic and non-
residents.
R roads that have time restrictions (e.g.
closed on Sundays and public holidays) are
avoided for route guidance.
Change of direction
Introduction
Changes of direction have three phases:
R preparation phase
R announcement phase
R change-of-direction phase
Preparation phase
COMAND prepares you for the upcoming
change of direction. Based on the example
display below, the change of direction is
announced with a message. You see the full-
screen map.
Example display: preparation phase
:Next road;Route=Current vehicle position (the tip of the
triangle indicates the vehicle’s direction
of travel)?Current road
The display in ? depends on the setting
selected under "Text information on the map"
( Y page 185).
Announcement phase
COMAND announces the imminent change of
direction. With reference to the following
example display, the announcement is given
166NavigationCOMAND

before the change of direction with the
request Please turn right in 900 ft .
The announced distance to the next change
of direction depends on the type of road and
its permissible speed limit.
The display is now split into two sectors. In
the left half, you see the normal map view.
The right half shows an enlarged section of
the area around the intersection (Crossing
Zoom) or a 3D image of the road's course with
the route indicating the next maneuver.
Example display: announcement phase
:Next road;Point at which the change of direction
takes place (light blue dot, shown in both
the left and right displays)=Graphic representation of the distance to
the next change of direction?Change of direction (turn right here)ADistance to the next change of directionBRoute (highlighted in blue, shown in both
the left and right displays)
i The filled-in section of visual display for
distance = gets shorter, the nearer you
get to the announced change of direction.
Change-of-direction phase
COMAND announces the imminent change of
direction. In the example, the Now turn
right announcement is made 100 ft. before
the change of direction. The display is split
into two halves, as in the announcement
phase.
Example display: change-of-direction phase
:Current vehicle position: the tip of the
triangle indicates the vehicle’s direction
of travel;Graphic representation of the distance to
the next change of direction=Distance to the next change of direction
Once the change of direction is completed,
COMAND automatically switches back to full-
screen display.
Lane recommendations
Overview
On multilane roads, COMAND can display
lane recommendations for the next change of
direction. The corresponding data must be
available in the digital map.
COMAND displays lane recommendations
B , based on the next two changes of
direction. The number of lanes applies to the
point at which the next change of direction is
required.

Using car pool lanes
COMAND displays car pool lanes if you have
selected this option in the route options
( Y page 152).
If this is the case, COMAND checks whether
there are any car pool lanes on the route. If
there are, they are taken into account during
route calculation. Route guidance will then
include car pool lanes.
Car pool lanes may only be used under certain
conditions. Please observe the relevant legal
requirements.

Off-road
Important safety note
GWARNING
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
appropriateness 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 consideration
by the COMAND system.
Route guidance to a destination that is not
on a digitized road
COMAND can guide you to destinations
which are within the area covered by the
digital map, but which are not themselves
recorded on the map.
These destinations are known 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 announcements and displays on
roads known to the system.Example display: route guidance to an off-road
destination
:Off-road destination;Off-road route section (dashed blue)=Current vehicle position (the tip of the
triangle indicates the vehicle’s direction
of travel)?Off-road (no street names available)
If the vehicle reaches an area which is not part
of the digital map, the display appears as a
split-screen view. On the right-hand side, an
arrow appears which points to off-road
destination :. You will hear the
announcement: "Please follow the arrow on
the display".
Route guidance from an off-road location
to a destination
If the vehicle position is within the area
covered by the digital map, but the map does
not contain any information about that
location, the vehicle is in an off-road location.
COMAND is also able to guide you to a
destination even from an off-road location.
At the start of the route guidance, you will see
the Street unknown message, an arrow and
the distance to the destination. The direction
arrow shows the linear direction to the actual
destination.
The continuous blue line on the map starts at
the street which you left last.
As soon as the vehicle is back on a road
known to the system, route guidance
continues in the usual way.
Navigation173COMANDZ

Off-road during route guidance
Due to roadworks, for example, there may be
differences between the data on the digital
map and the actual course of the road.
In such cases, the system will temporarily be
unable to locate the vehicle position on the
digital map and thus considers the vehicle to
be in an off-road position.
In the display, you will see the Street
unknown message, an arrow and the distance
to the destination. The arrow shows the
compass heading to the last road you were
driving on.
As soon as the system can assign the vehicle
position to the map again, route guidance
continues in the usual way.
Route guidance on roads that are not
completely digitalized
COMAND attempts to avoid roads that have
not been completely digitalized. If the
vehicle's position or the destination is located
in an area that has not been completely
digitalized, then no active route guidance is
performed. Instead, the map shows a dashed
route along the roads and the target direction
is shown with an arrow. You hear the
announcement: "You will enter an area,
where turn-by-turn guidance can not be
provided. Please follow the arrow on the
display". Once these roads have been left,
regular route guidance is resumed.
Traffic reports
Prerequisite
i The SatRadio mode described below
requires optional satellite radio equipment
and a subscription to SIRIUS XM Satellite
Radio Traffic Message Service. Further
details on SatRadio are available in the
"SatRadio" section ( Y page 216).
COMAND can receive traffic reports via
SatRadio and incorporate them in the
navigation system. Traffic messages and map
symbols can then be shown in the COMAND
display.
COMAND uses high quality traffic data.
Nevertheless, there may be differences
between the traffic reports received and the
actual road and traffic conditions.
Switching traffic reports on/offXTo switch on: set the route type to
Dynamic Route 7
(Y page 152).XTo switch off: select the Fast Route or
Short Route route type (Y page 152).
i
COMAND calculates a new route if you
change the route type setting with route
guidance active. If you change the route
type setting when route guidance is
inactive, COMAND uses the new setting for
the next route guidance.
Real-time traffic reports on the map
COMAND can show certain traffic incidents
on the map. The incidents are shown on the
map at a scale from 1/16 mi to 20 mi.
