JBL HI-FI system
Your vehicle may be equipped with a JBL Hi-Fi system,specially designed to fit in with your cabin interior.
Adjustment in CD or radio mode
The basic functions remain the same as those for the radio. No extra adjustment is necessary. However, to profit fully from your JBL audio system, you are recommended to adjust the audio functions: bass (Bass), treble (Treb), front/rear balance (Fad), left/right balance (Bal) to position O, Loudness (Loud) to position ON for listening to a CD and position OFF for listening to the radio.
