Introduction
Safety notes G
WARNING
For safety reasons, only enter a new
destination when the vehicle is stationary.
When you are driving, another passenger
should enter the destination. Read the
Operator's Manual and select the route
before driving.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h

), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second.
COMAND calculates the route to the
destination without taking account of the
following, for example:
R traffic lights
R stop and give way signs
R merging lanes
R parking or stopping in a no parking/no
stopping zone
R other road and traffic rules and regulations
R narrow bridges G
WARNING
COMAND may give incorrect navigation
commands if

the actual road/traffic situation
no longer corresponds to the data on the digital map. Digital maps do not cover all
areas nor all routes in an area. For example,
a route may have been diverted or the
direction of a one-way street may have
changed.
For
this

reason, you must always observe road
and traffic rules and regulations during your
journey. Road and traffic rules and regulations
always have priority over the system's driving
recommendations. G
WARNING
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.
Looking at the icons or map display can
distract you from traffic conditions and
driving, and increase the risk of an accident.
General notes Operational readiness of the navigation
system
The navigation system must determine the
position of the vehicle before first use or
whenever operational status is restored.
Therefore, you may have to drive for a while
before precise route guidance is possible.
GPS reception
Correct functioning of the navigation system
depends, amongst other things, on GPS
reception. In certain situations, GPS
reception may be impaired, there may be
interference or there may be no reception at
all, e.g. in tunnels or parking garages.
Entry restriction
On vehicles for certain countries, there is a
restriction on entering data.
The
restriction

is active from a vehicle speed
of above approximately 3 mph (5 km/h). As
soon as the speed falls below approximately Navigation
