SWITCHES

HEADLIGHT DIMMER AND TURN
SIGNAL SWITCH
12L003
For high beam, push the lever forward. Pull it back for low
beam. For the headlight flasher, pull it further back.
A blue light in the instrument cluster indicates high beam or
headlight flasher is on.
The headlight flasher works even when the headlight switch is off.
12L004
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ”ON” position.
The turn signal is selfcancelling after a turn, but after a lane change,
you may have to cancel it by hand. You can also signal a lane change
by moving the turn signal lever partway and holding it there.
If the green light in the instrument cluster flashes faster than normal,
it indicates that the front or rear turn signal bulb has burned out. If
this indicator light does not come on, the fuse or the indicator light
itself has probably failed.

POWER OUTLET

power outlet longer than necessary when the engine is not
running.

Push this button on the upper side to step up the station band or
on the lower side to step down.
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.
In this case, ”ST” disappears from the display.(b) Presetting a station
20L047-1
1. Tune in the desired station.
2. Push one of the station selector buttons ( 16 ) and hold it until
a beep is heard. This sets the station to the button and the button
number ( 16 ) appears on the display.
Each button can store one AM station and two FM stations. To
change the preset station to a different one, follow the same
procedure.
The preset station memory is cancelled when the power source is
interrupted by battery disconnection or a blown fuse.
