Turn and Lane-Change Signals
Turn Signal
Move the signal lever down (for a left turn) or up (for a right turn) to the stop position. The signal will self-cancel after the turn is completed.

If the indicator light continues to flash after a turn, manually return the lever to its original position.
Green indicators on the dashboard show which signal is working.
Lane-change signals
Move the lever slightly toward the direction of the change ―until the indicator flashes― and hold it there. It will return to the off position when released.
NOTE:
If an indicator light stays on without flashing
or if it flashes abnormally, one of the turn
signal bulbs may be burned out.
