Turn and Lane-Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is finished, the lever will return
automatically.
To signal a lane change, just raise or lower the lever
until the arrow starts to flash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it.
3-8
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
If the arrows flash very fast as you signal a turn or a
lane change, a signal bulb may be burned out and other
drivers will not see your turn signal. If a bulb is burned
out, replace it to help avoid an accident. See Bulb
Replacement on page 5-52.
If the arrows do not go on at all when you signal a turn,
check the fuse. See Fuses and Circuit Breakers on
page 5-101.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
