211 Control systems
COMAND navigation system (route guidance)
During route guidance, the display is divid-
ed. On the right-hand side you will see the
direction arrow showing the compass
heading to the destination.
On the left-hand side of the display you will
see the map with the suggested route. The
suggested route is highlighted blue. How-
ever, it may not be possible to follow the
suggested route because, for example, the
road is closed or not open for car traffic.
If, during route guidance, COMAND leads
you back into a fully digitalized area, route
guidance will simply continue in the usual
manner.Off-road and off-map
Route guidance to an off-road
destination
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
the point to leave the digitized road net-
work, 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 indicated with a dashed line
after a certain length. It simply shows the
direction to the off-road destination with-
out taking account of any type of obstacles
in the way.
Warning!G
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.

Warning!G
Navigation announcements are intended to
direct you while driving without diverting
your attention from the road and driving.
Please always use this feature instead of
consulting the map display for directions.
Consulting the symbols or map display for
directions may cause you to divert your at-
tention from driving and increase your risk
of an accident.
iIf Russian or Chinese is set as the system
language, the navigation announcements are in
English. You will find how to set the system lan-
guage on (
page 238).
Navigation announcements are muted during
telephone calls. You can, however, call up a cur-
rent announcement at any time. You can also
call up a current announcement at any time if
you have missed an announcement.

If you switch COMAND off by removing the
SmartKey from the starter switch and then
switch the ignition back on after more than
3 minutes, the announcements are automatical-

COMAND address book
General notes
The address book contains the entries that
are saved in the COMAND address book
memory. The entries are permanently
available even if the phone is not inserted
in the cradle*. When you insert the mobile
phone into the cradle*, COMAND reads-in
the phone book entries saved in the mobile
phone and stores the entries as a separate
list from the COMAND address book. This
list is a copy of the phone’s phone book.
This can take several minutes, depending on how many entries the phone book and
the address book contain. After the read-in
process, the COMAND compares the
phone book entries with the address book
entries. If all of the telephone numbers of a
phone book entry in the mobile phone are
present in an address book entry, the ad-
dress book shows only the address book
entry. If not, the address book also shows
the phone book entry in the mobile phone.

Warning!G
Please devote your attention first and fore-
most to the traffic situation you are in.
Before your journey, please familiarize your-
self with the address book functions.
Only use the COMAND when road and traffic
conditions permit you to do so. Otherwise
you could be involved in an accident in
which you or others could be injured.

ber.

iThe components and operating principles of
COMAND can be found on (
page 85).
Warning!G
When operating the automatic climate con-
trol, the air that enters the passenger com-
partment through the air vents can be very
hot or very cold (depending on the set tem-
perature). This may cause burns or frostbite
to unprotected skin in the immediate area of
the air vents.
Always keep sufficient distance between un-
protected parts of the body and the air
vents. If necessary, use the air distribution
adjustment (
page 253) to direct the air to
air vents in the vehicle interior that are not
in the immediate area of unprotected skin.
Warning!G
Follow the recommended settings for heat-
ing and cooling given on the following pages
and pages in the “Controls in detail” part
