Ignition Positions With the key in the ignition switch, you can turn the key to four different positions. If you cannot start your vehicle and you are unable to remove your key from the ignition, see "Shift Lock Release" later in this section for more information. 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? If it is, then turn the steering wheel left and right while you turn the key hard. Turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of these works, then your vehicle needs service. A (OFF): This is the only position in which you can insert or remove the key. This position locks the ignition, steering wheel and transaxle. It's a theft-deterrent feature. B (ACCESSORY): This position allows you to use things like the radio and the windshield wipers when the engine is off. This position will allow you to turn off the engine, but still turn the steering wheel. If your vehicle has a column shifter, you will still be able to move the shift lever. Use ACCESSORY if you must have your vehicle in motion while the engine is off, for example, if your vehicle is being pushed or towed. C (ON): This position is for driving. If your vehicle has a console shifter and you turn off the engine, the transaxle will lock. If you need to shift the transaxle out of PARK (P), the ignition key has to be in ON. D (START): This position starts the engine. 2-26
