Before you use the telephone
Warning!
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so
could lead to a malfunction of the vehicle’s elec-
tronic systems, possibly resulting in an accident
and personal injury.
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
• Please read this section first before attempting to
operate your telephone.
• Always drive with extreme caution when you
operate the telephone hands-free.• Do not stop or park in no-parking areas to use the
telephone.
• Close the windows and reduce all outside noise as
much as possible when you use hands-free opera-
tion.
• If the signal strength is very weak (display in the
symbol field of all main menus) you should not
make telephone calls. Wait until reception im-
proves.
• A brief disconnection from the cellular network
is not a malfunction, as this can occur when the
network switches areas.
• If you are required to enter the unlock code when
you switch the COMAND operating unit on, enter it
to be able to use all of the telephone functions.
Enter the unlock code, see page 86.
