Ignition Positions - Chevrolet 2004 Corvette Owner's Manual

Ignition Positions

OFF: This is the only position from which you can
remove the key.
If you have an automatic transmission, the ignition
switch cannot be turned to OFF unless the shift lever
is in PARK (P).
ACC (ACCESSORY): This is the position in which you
can operate your electrical accessories.
2-20
With the key in the ignition
switch, you can turn it to
four different positions.
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 not 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 while 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.
