RADIO OPERATION AND MOBILE PHONES
Under certain conditions, the mobile phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the mobile phone. This condition is not
harmful to the radio. If your radio performance does not
satisfactorily “clear” by the repositioning of the phone, it
is recommended that the radio volume be turned down
or off during mobile phone operation when not using
Uconnect® (if equipped).
