The turn signal has an upward (for right) and a downward (for left) position. 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.
An arrow on the instrument panel cluster will flash in the direction of the turn or lane change.
To signal a lane change, raise or lower the lever until the arrow starts to flash. Hold it there until you complete the lane change. The lever will return by itself when you release it.
As you signal a turn or a lane change, if the arrows flash rapidly, a signal bulb may be burned out and other drivers won't see your turn signal.
If a bulb is burned out, replace it to help avoid an accident. If the arrows do not go on at all when you signal a turn, check the fuse, see Fuses and Circuit Breakers and for burned-out bulbs.
