Telephone*
Important notes
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 is
displayed, enter the unlock code
( page 76). Only then will you be able
to use all the telephone functions.
You will still be able to make 911 emer-
gency calls ( page 74) if the tele-
phone is locked.
