TREB (Treble) Type 1−2 only This knob lets you adjust treble level. Push "BASS/TREB" so that it pops out of its retracted position. Pull out the knob. Turn the knob to adjust the treble. Push the knob back into its retracted position. TUNE Tuning Your Toyota has an electronic tuning radio (ETR). Push and release the "∧" (up) or "∨" (down) side of "TUNE" to step up or down the station band. If you hear a beep, you held the button too long and the radio will go into the seek mode. Seeking In the seek mode, the radio finds and plays the next station up or down the station band. To seek a station, push and hold the "∧" or "∨" side of "TUNE" until you hear a beep. Do this again to find another station. 94
