Turn and Lane-Change Signals

An arrow on the instrument panel cluster will flash in the direction of the turn or lane change.
Move the lever all the way up or down to signal a turn.
Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is complete. If the lever is briefly pressed and released, the turn signal flashes three times.
The lever returns to its starting position when it is released.
If after signaling a turn or a lane change the arrows flash rapidly or do not come on, a signal bulb may be burned out.
Have the bulbs replaced. If the bulb is not burned out, check the fuse; see Fuses on page 10‑38 for more information.
