Useful information
i These operating instructions describe all
the standard and optional equipment of
your COMAND system, as available at the
time of going to print. Country-specific
differences are possible. Please note that
your COMAND system may not be
equipped with all the features described.
This also applies to safety-related systems
and functions.
i Read the information on qualified
specialist workshops: (Y page 33).Operating safety
Important safety notes
G
WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other
networked components. In particular,
systems relevant to safety could also be
affected. As a result, these may no longer
function as intended and/or jeopardize the
operating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as
electronic components or their software. You
should have all work to electrical and
electronic equipment carried out at a qualified
specialist workshop.
If you make any changes to the vehicle
electronics, the general operating permit is
rendered invalid. G
WARNING
If you operate information systems and
communication equipment integrated in the
vehicle while driving, you will be distracted
from traffic conditions. You could also lose
control of the vehicle. There is a risk of an
accident. Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the
equipment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating COMAND.
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
COMAND can give incorrect navigation
commands if the actual street/traffic
situation does not correspond with the digital
map's data. 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.
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.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/ h)your vehicle covers
a distance of 44 feet (approximately 14 m)
per second. 286
