Ignition Positions
Use the key to turn the ignition switch to four different
positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.A (OFF):This is the only position in which you can
insert or remove the key. This position locks the ignition
and transmission. It is a theft-deterrent feature.
Notice:Lengthy operation of features such as the
radio in the accessory ignition position may
drain the battery and prevent your vehicle from
starting. Do not operate your vehicle in the
accessory ignition position for a long period
of time.
B (ACCESSORY):This position lets you use things like
the radio and the windshield wipers when the engine
is off.
C (RUN):This is the position for driving.
D (START):This position starts the engine.
