The vehicle has one of these radios as its audio system.

Radio Data System (RDS)

The Radio may have a Radio Data System (RDS). The RDS feature is available for use only on FM stations that broadcast RDS information. This system relies upon receiving specific information from these stations and only works when the information is available. While the radio is tuned to an FM-RDS station, the station name or call letters displays. In rare cases, a radio station could broadcast incorrect information that causes the radio features to work improperly. If this happens, contact the radio station.

Playing the Radio

(Power/Volume): Press to turn the system on and off. Turn clockwise or counterclockwise to increase or decrease the volume. When the radio is turned on, it plays at the volume level that was last set. The volume can be adjusted using this knob.

(Information) (AM-FM Radio and Radio with CD (Base)): Press to switch the display between the radio station frequency and the time. While the ignition is off, press to display the time.

(Information) (MP3 and RDS Features): Press to display additional text information related to the current FM-RDS station or MP3 song. A choice of additional information such as: Channel, Song, Artist, and CAT (category) can display. Continue pressing to highlight the desired label, or press the pushbutton positioned under any one of the labels and the information about that label displays. When information is not available, No Info displays.

(Clock) (AM-FM Radio and Radio with CD (Base)): The radio has a clock button for setting the time. With this type of radio, the clock can be set with either the radio turned on or off. See Setting the Clock for more information.

Speed Compensated Volume (SCV): Radios with Speed Compensated Volume (SCV) automatically adjusts the radio volume to compensate for road and wind noise as you speed up or slow down while driving. That way, the volume level should sound about the same as you drive.

To activate SCV:

  1. Set the radio volume to the desired level.
  2. Press the MENU button to display the radio setup menu.
  3. Press the pushbutton under the AUTO VOLUM label on the radio display.
  4. Press the pushbutton under the desired Speed Compensated Volume setting (OFF, Low, Med, or High) to select the level of radio volume compensation. The display times out after approximately 10 seconds. Each higher setting allows for more radio volume compensation at faster vehicle speeds.

Finding a Station

BAND: Press to switch between FM1 and FM2 and AM. The selection displays.

(Tune): Turn clockwise or counterclockwise to increase or decrease the station frequency.

SEEK : Press the arrows to go to the previous or to the next station and stay there. To scan stations, press and hold either arrow for two seconds until a beep sounds. The radio goes to a station, plays for a few seconds, then goes to the next station. For AM-FM Radio and Radio with CD (Base), the station frequency flashes while the radio is in the scan mode. Press either arrow again to stop scanning. The radio seeks and scans stations only with a strong signal that are in the selected band. For AM-FM Radio and Radio with CD (Base), scan presets within the current selected band by pressing and holding either SEEK arrow for four seconds until a double beep sounds. The radio goes to a stored preset, plays for a few seconds if a strong signal is present, then goes to the next stored preset. The station frequency flashes while the radio is in the scan mode.

Setting Preset Stations

If the radio does not have XM™, up to 18 stations (six FM1, six FM2, and six AM), can be programmed on the six numbered pushbuttons, by performing the following steps:

FAV (Favorites): If the vehicle has XM™ and has a FAV button, a maximum of 36 stations can be programmed as favorites using the six pushbuttons positioned below the radio station frequency labels and by using the radio favorites page button (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 and FM stations.

To insert one CD, do the following:

  1. Press and release the button.
  2. Wait for the message to insert the disc.
  3. Load a CD. Insert the CD partway into the slot, label side up. The player pulls the CD in.

The CD player can play the smaller 3 inch (8 cm) single CDs with an adapter ring. Full-size CDs and the smaller CDs are loaded in the same manner.

Care of Your CDs and DVDs

If playing a CD-R, the sound quality can be reduced due to CD-R or CD-RW quality, the method of recording, the quality of the music that has been recorded, and the way the CD-R or CD-RW has been handled. Handle them carefully. Store CD-R(s) or CD-RW(s) in their original cases or other protective cases and away from direct sunlight and dust. The CD or DVD player scans the bottom surface of the disc. If the surface of a CD is damaged, such as cracked, broken, or scratched, the CD does not play properly or not at all. Do not touch the bottom side of a CD while handling it; this could damage the surface. Pick up CDs by grasping the outer edges or the edge of the hole and the outer edge.

If the surface of a CD is soiled, take a soft, lint free cloth or dampen a clean, soft cloth in a mild, neutral detergent solution mixed with water, and clean it. Make sure the wiping process starts from the center to the edge.

Care of Your CD and DVD Player

Do not add any label to a CD, it could get caught in the CD or DVD player. If a CD is recorded on a personal computer and a description label is needed, try labeling the top of the recorded CD with a marking pen.

The use of CD lens cleaners for CDs is not advised, due to the risk of contaminating the lens of the CD optics with lubricants internal to the CD and DVD player mechanism.

Notice: If a label is added to a CD, or more than one CD is inserted into the slot at a time, or an attempt is made to play scratched or damaged CDs, the CD player could be damaged. While using the CD player, use only CDs in good condition without any label, load one CD at a time, and keep the CD player and the loading slot free of foreign materials, liquids, and debris.

If an error displays, see "CD Messages" later in this section.

Using the Auxiliary Input Jack

Your radio system has an auxiliary input jack located on the lower right side of the faceplate. This is not an audio output; do not plug the headphone set into the front auxiliary input jack. An external audio device such as an iPod, laptop computer, MP3 player, CD changer, etc. can be connected to the auxiliary input jack for use as another source for audio listening.

Drivers are encouraged to set up any auxiliary device while the vehicle is in P (Park). See Defensive Driving for more information on driver distraction.
