On most vehicles, the ignition switch can be turned to four positions: ACCESSORY, OFF, ON, and START. See figure . An optional three-position keyless ignition switch does not have the ACCESSORY position.

The key can be inserted and removed only from the OFF position. The headlights (low beams), brake lights, fog lights, dome lights, clearance lights, turn signals, hazard warning lights, and the parking lights operate with the ignition switch in the OFF position, regardless of whether the key is inserted.

Turn the key fully clockwise to the START position, only when starting the engine. When the engine starts, release the key. When released, the key will rotate counterclockwise to the ON position.

In the ON position (key turned 45 degrees clockwise), all electrical systems are operable. The warning lights and the buzzer for low engine oil pressure operate until the engine is started and minimum engine oil pressure is achieved.
