Removing The Key From The Ignition; Key Release Button (Manual Transmission Only) - Ford 1996 Mustang Manual

ON allows you to test your vehicle's warning
lights (except the brake system warning light) to
make sure they work before you start the
engine. The key returns to the ON position once
the engine is started and remains in this position
while the engine runs.
START cranks the engine. Release the key once
the engine starts so that you do not damage the
starter. The key should return to ON when you
release it. The START position also allows you
to test the brake warning light.
