Turn Signals
Move the lever up or down to signal a right-hand or
left-hand turn.
The arrow on either side of the instrument cluster flashes
to indicate the direction of the turn, and proper operation
of the front and rear turn signal lights. If a defective bulb
or wiring circuit is detected for the turn signal system, the
arrow indicators will flash at a faster rate. If an indicator
fails to light when the lever is moved, it would suggest
that the switch or indicator lamp is defective.
Turn Signal Lever
Lane Change Assist
Tap the lever up or down once and the turn signal (left or
