FEATURES AND BENEFITS

• | 6 AM / 12 FM Radio Station Presets: Programmable by following two steps:

1. | Tune in desired station on the desired band.

2. | Push and hold the desired preset button for approximately one second (until an audio confirmation beep is heard).

• | A.SET (Automatic Station Set): Samples and picks out the strongest radio stations on the band, starting from the lowest station frequency.

• | Electronic Tuning: Automatically locks in station signals for best possible reception.

• | Seek Tuning: Provides up and down seek capability for radio bands to search for the next receivable station.

• | Scan Tuning: Samples program selection for five seconds and then automatically moves to the next radio station. An audible tone indicates Scan mode searching.

• | Automatic Loudness Compensation: Full depth of sound can be heard at low volume levels.

• | Rotary Pull-Out Balance Control: Pull-out control allows balance adjustment, then the control pushes-in to lock the balance in place.

• | Rotary Pop-Out Bass Control: Pop-out control allows bass adjustment, then the control pushes-in out of the way and locks the bass in place.

• | Rotary Pop-Out, Then Pull Treble Control: Pop-out then pull control allows treble adjustment, then the control pushes-in out of the way and locks the treble in place.

The Time of Day (Clock) will be displayed when:

1. The ignition is turned off and the radio power is either On or Off. (Press RCL button if back lighting is desired.)
2. The ignition is turned On and the radio power is Off.
3. The ignition is turned On, the radio is On, and the tune, seek, scan, or preset function has not been activated for ten seconds.

• | Setting the Time of Day (Clock):

1. | Push and hold the RCL (Recall) button.

2. | While holding the RCL button, push the left side of the Tune/Seek rocker button until the correct hour appears.

3. | While holding the RCL button, push the right side of the Tune/Seek rocker button until the correct minute appears.

4. | Release the RCL button when complete.

• | Dimming:

| All radios feature continuously dimmable nighttime incandescent back lighting for the graphics on the pushbuttons and trimplate. The incandescent back lighting voltage is supplied from the vehicle light switch and is grounded through the radio wiring harness and the radio ground strap. The internal lamps are controlled by the high side pulse width modulated (PWM) dimmer control circuit through the BCM.

| The LCD is backlit whenever ignition voltage is applied regardless if the radio power knob is on or off. When the vehicle's exterior lights are turned On, the interior lights knob, which is found to the left of the steering wheel, can be turned to adjust the illumination of the radio. Turning the knob clockwise makes the light get brighter, while turning the knob counter-clockwise results in the light being dimmer.
