Whether or not prohibited by law, for safety
reasons, the driver should not use the cellu-
lar telephone while the vehicle is in motion.
Stop the vehicle in a safe location before
placing or answering a call.

phone while driving, please use the hands-
free device and be sure to pay attention to
the traffic situation at all times. Use the cel-
lular phone
1 only when road, weather and
traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
WarningG
Never operate radio transmitters provided
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to malfunction
of the vehicle's electronic system, possibly
resulting in an accident and/or personal
injury.
Tips on telephone operation
i
Once the cellular phone is inserted into
the telephone cradle*, it can be operat-
ed:
using the cell phone itself,
using the COMAND control unit,

Important notes
Please read chapter “Telephone*” be-
fore attempting to operate your tele-
phone.
Always drive with extreme caution
when operating the telephone hands-
free.
For safety reasons, the mobile tele-
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 is dis-
played, enter the unlock code
(
page 91). Only then will you be able
to use all the telephone functions.
You will still be able to make 911 emer-
gency calls (
page 89) if the tele-
phone is locked.
