With the key in the ignition switch, you can turn it to four different positions.


Object Number: 810336  Size: B3
A (OFF): This is the only position from which you can remove the key. The shift lever must be in PARK (P) with the ignition in OFF to remove the key. A warning chime will sound if you open the driver's door when the ignition is off and the key is in the ignition.

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.

B (ACCESSORY): This position unlocks the transaxle. It also lets you use things like the radio and windshield wipers when the engine is not running. To use ACCESSORY, turn the key clockwise to the first position. Use this position if your vehicle must be towed.

C (ON): This position is where the key returns to after you start your engine and release the key. The ignition 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 warning lights.

D (START): This position starts the engine. When the engine starts, release the key. The ignition switch will return to ON for normal driving.
