The ignition switch includes a device that helps prevent accidental removal of the key while driving.
The key can only be removed when the ignition switch is in the LOCK position.
On manual transmission models, to turn the ignition key to LOCK position from ACC or ON position, turn the key to OFF, push the key in, then turn the key to LOCK.
In order for the steering wheel to be locked, it must be turned about 1/8 of a turn clockwise from the straight up position.
To lock the steering wheel, turn the key to the LOCK position. Remove the key. To unlock the steering wheel, insert the key and turn it gently while rotating the steering wheel slightly right and left.
