off (for example, if your vehicle is being pushed).
RUN - This is the position for driving.
START - This starts your engine.
NOTICE:
If your key seems stuck in LOCK and you can't turn it, be sure
it is all the way in. If it is, then turn the steering wheel left and
right while you turn the key hard.'But turn the key only with
your hand. Using a tool to force it could break the key or the
ignition switch. If none of this works, then your vehicle needs
service.
