Ignition Switch
Your ignition switch has four (unmarked) positions:
• ACC (Accessory): With your key in this position you
can play the radio or use other accessories, but your
engine won’t start.
The four-way Emergency Flasher switch is located to the
right of the ignition key switch. With the switch in the ON
position, the emergency flasher makes all four turn signals
(front and rear) flash simultaneously. The flasher
works independently of the ignition switch. You should
always use the flasher if the vehicle is disabled or parked
under emergency conditions.
