Driving and Operating LOCK/OFF: This is the only position from which you can remove the key. This locks the steering wheel, ignition and automatic transmission. Push in the ignition switch as you turn the key toward you. On vehicles with an automatic transmission, the shift lever must be in P (Park) to turn the ignition switch to the LOCK/OFF position. A warning tone will sound if the driver door is opened with the key in the ignition. The ignition switch can bind in the LOCK/OFF position with your wheels turned off center. If this happens, move the steering wheel from right to left while turning the key to ACC/ACCESSORY. If this doesn't work, then the vehicle needs service. 8-17 { CAUTION On manual transmission vehicles, turning the key to LOCK/OFF and removing it 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 only to ACC/ ACCESSORY. Do not push the key in while the vehicle is moving. ACC/ACCESSORY: This position provides power to some of the electrical accessories. It unlocks the steering wheel and ignition. To move the key from ACC/ACCESSORY to LOCK/OFF, push in the key and then turn it to LOCK/OFF. A warning tone will sound when the driver door is opened when the ignition is still in ACC/ACCESSORY or LOCK/OFF and the key is in the ignition. ON/RUN: The ignition switch stays in this position when the engine is running. This position can be used to operate the electrical accessories, including the ventilation fan and 115 volt power outlet, as well as to display some warning and indicator lights. The transmission is also unlocked in this position on automatic transmission vehicles. The battery could be drained if you leave the key in the ACC/ ACCESSORY or ON/RUN position with the engine off. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. START: This position starts the engine. When the engine starts, release the key. The ignition switch will return to ON/RUN for normal driving.
