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.
As you signal a turn or a lane change, if the arrows
don't flash but just stay on, check the turn signal flasher
and circuit breaker. See Fuses and Circuit Breakers
on page 5-65 .
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you
signal a turn, check the circuit breaker and for
burned-out bulbs.
An arrow on the instrument
panel cluster will flash in
the direction of the
turn or lane change.
