2004 Chevrolet Blazer Owner's Manual - Page 86

{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. Do not press the key release button while the vehicle is moving. 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 all the way in. If it is, turn the steering wheel left and right while you turn the key hard. If none of this works, then your vehicle needs service. B (LOCK): This position locks your ignition when the key is removed. The steering wheel locks when equipped with a manual transmission. It's a theft-deterrent feature. You will only be able to remove your key when the ignition is turned to LOCK. C (OFF): This position lets you turn off the engine but still turn the steering wheel. Use OFF if you must have your vehicle in motion while the engine is off (for example, if your vehicle is being towed). D (RUN): This is the position for driving. E (START): This position starts your engine. Key Release Button The key cannot be removed from the ignition of manual transmission vehicles unless the key release button is pressed. To remove the key, turn the ignition switch to OFF. Then turn the key to LOCK while pressing the key release button. Pull the key straight out. 2-20
