starts to flash to signal a lane
change. This causes the turn

one second will cause the turn
signals to flash until the lever is
released.
The lever returns to its starting
position whenever it is released.
If after signaling a turn or a lane
change the arrows flash rapidly or
do not come on, a signal bulb could
be burned out.

bulb is not burned out, check the
fuse. SeeFuses on page 10-33.
