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

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.
