compatible. If this is the case, the navigation
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
software must be updated now. Please
insert the DVD with the map software.XUpdating map software: Proceed as
described in the “Updating the map
software” section ( Y page 96). Use map
software which is compatible with the
system software.
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-operational.
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
The Navigation system relies on a number of
factors to function correctly. GPS reception
is very important.
In certain situations GPS may be impaired, for
example:
R in tunnels
R in parking garages
R due to snow on the GPS antenna
If there is snow on the GPS antenna, you
should remove it. The GPS antenna is at the
back of the vehicle roof.
A roof cargo container may also impair GPS
coverage.
Route guidance after transporting the
vehicle or exiting a parking garage
COMAND has to redetermine the position of
the vehicle if the vehicle has been transported
(e.g. by ferry, by train or after towing).
COMAND may also have to redetermine the
vehicle position when leaving a parking
garage.
The proper position of the vehicle will even be
found if you are driving with COMAND
switched off. The duration of the positioning
recalculation will vary case by case.
During positioning, route guidance may be
inaccurate and may show the following:
R Navigation announcements, route
guidance displays and displayed street
names are not consistent with the actual
location of the vehicle.
R COMAND does not generate navigation
announcements.
R Instead of the route guidance displays, you
see the Off Road display and a direction
arrow. The direction arrow shows the
compass heading to the destination.
After the vehicle position has been
redetermined, route guidance with navigation
announcements and route guidance display
is available again.
Interrupting the journey during route
guidance
The following applies if you interrupt the
journey during route guidance and continue
the journey later:
R COMAND resumes route guidance
automatically if you continue the journey
within 2 hours.
R Route guidance is canceled if you continue
the journey after more than 2 hours. It will
be necessary to resume the canceled route
guidance manually ( Y page 135).
i The journey is interrupted if you park the
vehicle and switch off COMAND. The

The doors are designed to unlock
automatically after an accident if the force of
the impact exceeds a preset threshold.
The vehicle locks automatically when the
ignition is switched on and the wheels are
turning at a vehicle speed of above 9 mph
(15 km/h). You could therefore lock yourself
out when the vehicle is pushed or towed or is
on a test stand.
Locking and unlocking from the inside
GObserve Safety notes, see page 56.
You can lock or unlock the vehicle from the
inside using the central locking or unlocking
switch. This can be useful, for example, if you

If the vehicle has been locked centrally with
the SmartKey or with KEYLESS-GO, it will not
unlock using the central unlocking switch.
Opening the trunk
GWarning!
Make sure the trunk is closed when the engine
is running and while driving. Among other
dangers, deadly carbon monoxide (CO) gases
may enter vehicle interior resulting in
unconsciousness and death.
! When you open the trunk, the trunk lid
swings open upwards. Always make sure
there is sufficient overhead clearance.
You can open the trunk when the vehicle is
stationary.
A minimum height clearance of 5.9 ft (1.80 m)

XStart the engine in the usual manner.
Parking
GWarning!
Do not park in areas where the hot exhaust
system could come into contact with
combustible materials. Combustible
materials such as grass, hay or leaves could
be ignited and cause a vehicle fire.
