Turn Signals
The turn signal lever
Move the lever up to signal a right turn. Move it down to
signal a left turn. The corresponding indicator light in the
instrument cluster will flash.
If the turn signal stays on after you turn, move the lever back
to the center (off) position.
For lane changes, move the lever far enough to signal but not to
latch. The lever will return to the off position when you release
it.
