yellowblue Key Release Button CAUTION: On manual transmission vehicles, turning the key to LOCK 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 OFF. Don't press the key release button while the vehicle is moving. The key cannot be removed from the ignition of manual transmission vehicles unless the key release button is used. NOTICE: If your key seems stuck in LOCK 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. But turn the key only with your hand. Using a tool to force it could break the key or the ignition switch. If none of this works, then your vehicle needs service. To remove the key on manual transmission vehicles, turn the key to OFF. Then turn the key to LOCK while pressing the key release button down at the same time. Pull the key straight out. On automatic transmission vehicles, turn the key to LOCK and pull it straight out. 2-18
