4RUNNER (1998) "Type 3 ST (Stereo reception) display Your radio automatically changes to stereo reception when a stereo broadcast is received. "ST" appears on the display. If the signal becomes weak, the radio reduces the amount of channel separation to prevent the weak signal from creating noise. If the signal becomes extremely weak, the radio switches from stereo to mono reception. TRACK (Track up/down Compact disc player button): TUNE (Tuning) 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. By using this button, you can skip up or down to a different track. Push either side of the track button until the number of the track you want to listen to appears on the display. If you want to return the beginning of the current track, push the down side of the button one time, quickly.
