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.
With the ignition key in the ignition, you can turn the
switch to five positions:
ACCESSORY (A): The accessory position lets you use
the radio and windshield wipers when the engine is off.
To use ACC, push in the key and turn it toward you.
Your steering wheel will stay locked.
LOCK (B): Before you put the key into the ignition
switch, the switch is in LOCK. It's also the only position
from which you can remove your key. This position
locks your ignition, steering wheel and transaxle. It's a
theft
-deterrent feature.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel. Use OFF if you must have your vehicle pushed
or towed.
RUN (D): This position is where the key returns after
you start your vehicle. With the engine off, you can
use RUN to display some of your warning and
indicator lights.
START (E): This position starts your engine.
A warning chime will sound if you open the driver's
door when the ignition is in OFF, LOCK or
ACCESSORY and the key is in the ignition.
