With the key in the ignition switch, you can turn it to four different 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).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/ACCESSORY.
Notice: Using a tool to force the key from the ignition switch could cause damage or break the key. Use the correct key and turn the key only with your hand. Make sure the key is in all the way. 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.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.
