Route guidance
General notes G
WARNING
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 Othe rroad 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 aroute has been
calculated (Y page 143).
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-
scree nmap. Example display: preparation phase
: Next road
; Route
= Curren tvehicle 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 173).
Announcement phase
COMAND announces the imminen tchange of
direction. With referencet o the following
example display, the announcement is given 154
NavigationCOMAND
before the change of direction with the
request
Please turn right in 900 ft .
The announced distance to the nex tchange
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:a
nnouncement phase
: Next road
; Point at which the change of direction
takes place (light blue dot, shown in both
the left and right displays)

the next change of direction
? Change of direction (turn right here)
A Distance to the next change of direction
B Route (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 imminen tchange of
direction. In the example, the Now turnright announcement is made 100 ft. before
the change of direction. The display is split
into two halves, as in the announcement
phase. Example display:c
hange-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. Navigation

The lane recommendations are also shown in

information in the "On-board computer"
section (Y page 341).
Using car pool lanes
COMAND displays car pool lanes if you have
selected this option in the route options
(Y page 139).
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. Example: display, car pool lane

Off-road Important safety note
G
WARNING
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 adestination 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 sectio n(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 Navigation
