Move the lever all the way up or down to signal a turn.
An arrow on the instrument cluster flashes in the direction of the turn or lane change.
Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is completed. If the lever is briefly pressed and released, the turn signal flashes three times.
The turn and lane-change signal can be turned off manually by moving the lever back to its original position.
If after signaling a turn or lane change the arrow flashes rapidly or does not come on, a signal bulb might be burned out.
Have any burned out bulbs replaced. If the bulb is not burned out, check the fuse.
