Chevrolet 2002 Corvette Owner's Manual page 81

CAUTION:
If you have a manual transmission, removing the
key from the ignition switch will lock the steering
column and result in a loss of ability to steer the
vehicle. This could cause a collision. If you need
to turn the engine off while the vehicle is moving,
turn the key to ACC.
NOTICE:
If your key seems stuck in OFF 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.
ON: This is the position to which the switch
returns after you start the engine and release the key.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON to operate your electrical accessories and to display
some instrument panel cluster messages and telltales.
START: This position starts the engine. When the
engine starts, release the key. The ignition switch will
return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the radio.
A warning tone will sound if you open the driver's door
when the ignition is in OFF or ACC and the key is in
the ignition.
Retained Accessory Power (RAP)
With RAP, your power windows and the audio system
will continue to work for up to 15 minutes after the
ignition key is turned to OFF and neither door is
opened. If a door is opened, the power windows and
audio system will shut off.
