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.
For signaling turns, move the lever up or down in the
conventional manner.
The ignition key must be in the ªONº position.
The turn signal is self±cancelling 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.
