Starting Your Engine - GMC 2001 Denali Owner's Manual

LOCK (B): This position locks your ignition and
-
transmission. It's a theft deterrent feature. You will only
be able to remove your key when the ignition is turned
to LOCK.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? 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.
OFF (C): This position lets you turn off the engine.
Use OFF if you must have your vehicle in motion
while the engine is off (for example, if your vehicle is
being pushed).
RUN (D): This position is for driving.
START (E): This position starts your engine.

Once the key is turned to OFF, these features will
continue to work for up to 20 minutes or until a door
is opened.
