Removing the Key From the Ignition
OFF/LOCK is the only position that allows you to remove the
key from the ignition. The LOCK feature helps to protect your
vehicle from theft, because it also locks the steering wheel
and the gearshift lever when the key is removed.
If your key is stuck in the LOCK position, and you are unable to
turn it, move your steering wheel left or right until the key
turns freely in the lock.
To remove your key from the ignition:
1. Put the gearshift lever in P (Park).
2. Set the parking brake fully.
3. Turn the ignition key to LOCK.
4. Remove the key.
When you leave your vehicle, place the gearshift lever in
P (Park). Set the parking brake fully, and shut off the
engine. Never park your vehicle in N (Neutral). If you do
not take these precautions, your vehicle may move
suddenly and injure someone.
Do not leave children, unreliable adults, or pets
unattended in your vehicle.
