Storing Radio Stations
Drivers are encouraged to store the radio station while the vehicle is parked; see Defensive Driving on page 9‑3. Tune to stored radio stations using the presets, favorites button, and steering wheel controls, if the vehicle has this feature.
Radios that have a FAV button store radio stations as favorites. Up to 36 stations can be programmed as favorites using the six softkeys below the radio station frequency tabs and by using the FAV button.
Press the FAV button to go through up to six pages of favorites, each having six favorite stations available per page. Each page of favorites can contain any combination of AM, FM, or XM, if equipped, stations.
Radios that do not have a FAV button store radio stations as presets. Up to 18 stations (6 FM1, 6 FM2, and 6 AM), can be programmed on the six numbered pushbuttons.
