Ignition Positions

CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons. A child or
others could be injured or even killed. They could
operate power windows or other controls or even
make the vehicle move. Don't leave the keys in
the vehicle with children.

Use your ignition key to
start your vehicle. You can
turn the ignition switch to
four different positions.
LOCK: This position lets you insert and remove the
ignition key.
ACC (Accessory): This position lets you use
accessories when the engine is off.
ON: This is the position for driving.
START: This position starts your engine.
Engine Starter Over-Crank Protection
(If Equipped)
Some vehicles have an engine starter over
protection system. This system includes a built
temperature limiting switch to prevent internal damage
to the starter. If the starter motor overheats and shuts off
-
due to over cranking, the motor must cool down before
the switch will reset and allow you to operate the starter.
It can take up to six minutes before the starter will
work again.
