This Operator's Manual describes op-
eration of the telephone using the
COMAND control unit and the multi-
function steering wheel. Unless other-
wise specified, the descriptions and
the illustrated displays refer to the
COMAND control unit.
Operation of the cellular phone and
voice control system* are explained in
separate operation guides.
Always drive with extreme caution
when operating the telephone hands-
free.
For safety reasons, the cellular phone
handset should not be used to place or
receive a call while driving.
If the signal is very weak (display in the
status bar):
Wait until reception improves before
placing a call.
Close the windows and reduce all ex-
ternal noise as much as possible when
using hands-free operation.
Make sure that the air vents are not
pointed in the direction of the micro-
phones located in the overhead control
panel near the rear view mirror. Adjust
air vents and/or reduce blower speed
if necessary.
A brief disconnection from the cellular
network is not a malfunction, as this
can occur when the network switches
areas. The phone automatically at-
tempts to again sign on with a network.
If the message Enter unlock code
displayed, enter the unlock code
( page 88). Only then will you be able
to use all the telephone functions.

gency calls ( page 85) if the tele-
phone is locked.
