COMAND navigation (introduction)
General notes
Operational readiness of the navigation
system following a system software
update by an authorized
Mercedes-Benz Center
After a system software update by an au-
thorized Mercedes-Benz Center, the in-
stalled map software may no longer be
compatible. If this is the case, the naviga-
tion system will not be operational.
You will know if this is the case, when the
following message will appear when you
switch to navigation mode: “The system
software has been updated. The map soft-
ware must be updated now. Please insert
the DVD with the map software.”
Updating map software: Proceed as
described in the “Updating the map
software” section (
page 183). Use
map software which is compatible with
the system software.Initial use or use following a system
software update
In both these cases, the navigation system
must determine the position of the vehicle.
You may have to drive for a while before
precise route guidance is possible.
GPS reception
Correct functioning of the navigation sys-
tem depends on GPS reception, among
other things. In certain situations, GPS re-
ception may be impaired, there may be in-
terference or no reception at all, e.g. in
tunnels, in multistory parking garages or
there is snow covering the trunk lid where
the GPS antenna is located. If there is
snow on the trunk lid it should be removed.Route guidance after vehicle transpor-
tation
COMAND has to redetermine the position
of the vehicle if the vehicle has been trans-
ported (e.g. by ferry, by train or after tow-
ing).
Positioning takes place automatically even
when COMAND is switched off. The dura-
tion varies from one case to another.
Route guidance may be restricted as fol-
lows during vehicle positioning:


Navigation announcements, route
guidance displays and displayed street
names are not consistent with the ac-
tual location of the vehicle.


COMAND does not generate navigation
announcements.


Instead of the route guidance displays,
you see the “Off Road” display and a di-
rection arrow. The direction arrow
shows the compass heading to the des-
tination.
i
Please note that the update must be allowed
to run to the end in this case. If you interrupt it,
the navigation system will continue to be non-op-
erational.

SmartKeys, each with remote control and
a removable mechanical key.
The SmartKey provides an extended oper-
ating range. To prevent theft, however, it is
advisable to only unlock the vehicle when
you are in close proximity to it.

G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
or trunk lid opening when closing a door or
the trunk. Be especially careful when small
children are around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.

When you open a door, the side windows on
that side lowers slightly. Once you close the
door, the window moves up again.
!
The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.
