GM Service Manual Online
For 1990-2009 cars only

Caution: To help avoid personal injury, always use jack stands when you are working on or under any vehicle that is supported only by a jack.

Caution: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist.

Notice: When you are jacking or lifting a vehicle at the frame side rails or other prescribed lift points, be certain that the lift pads do not contact the catalytic converter, the brake pipes or the fuel lines. If such contact occurs, vehicle damage or unsatisfactory vehicle performance may result.

Before you begin any lifting procedure, ensure that the vehicle is on a clean, hard, level surface. Ensure that all of the lifting equipment meets weight standards and is in good working order. Ensure that all of the vehicle loads are equally distributed and secure. If you are only supporting the vehicle at the frame side rails, ensure the lifting equipment does not put too much stress on or weaken the frame side rails.

If you use any other hoisting methods than those called out, use special care not to damage the fuel tanks, the exhaust system or the underbody.
