GM Century/Lumina/Grand Prix/Intrigue 1997-2000



Your vehicle was supplied with a jack for emergency tire changing. This jack is adequate for changing a flat tire or other short term procedures-NOT REQUIRING YOU TO GO UNDER THE VEHICLE. If it is used in an emergency situation, carefully follow the instructions provided either with the jack, in the owner's manual or on an instruction sticker near where the spare tire is stowed. DO NOT attempt to use this jack on any portion of the vehicle other than specified by the vehicle manufacturer as outlined in the owner's manual. Always block the diagonally opposite wheel when using a jack.

A more convenient way of jacking is the use of a garage type floor jack. You may use the floor jack to lift the front of the vehicle by positioning the jack in the center of the front crossmember. When raising the rear of the vehicle, position the jack on the rear jack pad.

Never place the jack under the radiator, engine or transmission components. Severe and expensive damage will result when the jack is raised. Additionally, never jack under the floorpan or bodywork; the metal will deform.

On the vehicles covered by this guide, do not place any jack under the engine oil pan, even with a so-called "protective" block of wood. The clearance between the oil pan the oil pickup assembly is very small and attempting to jack under the engine, for any reason, will cause damage to the engine oil pump pickup.

Whenever you plan to work under the vehicle, you must support it on jackstands (safety stands) or ramps. Never use cinder blocks (they crumble easily) or stacks of wood to support the vehicle, even if you are only going to be under it for a few minutes. Never crawl under the vehicle when it is supported only by the tire-changing jack or the floor jack.

Drive-on ramps are a handy and safe way to raise and support the vehicle. Use caution, since some ramps may be steep enough that some portion of the lower front bodywork may scrape when driving onto the ramps. Never support the vehicle on any suspension member (unless instructed to do so by a repair guide) or by an underbody panel.


The following safety points cannot be overemphasized:

Always block the opposite wheel or wheels to keep the vehicle from rolling off the jack.
When raising the front of the vehicle, firmly apply the parking brake, which works on the back wheels.
When the front drive wheels are to remain on the ground, place the shift lever in the PARK position to lock the transaxle, to keep the front wheels from rolling.
Always use jackstands to support the vehicle while you are working underneath. Place the stands beneath the vehicle's jacking brackets. Before getting under the vehicle, rock the vehicle a small amount to make sure it is firmly supported.
When supporting the vehicle with jackstands, the supports should be placed under the body pinchwelds or similar strong and stable structure. The vehicle should be on a clean, hard, level surface before any lifting procedure begins. All lifting equipment MUST be in good working order. Make sure all vehicle loads are equally distributed and secure. Note that the center of gravity of front wheel drive cars is further forward than on rear-drive vehicles.
When jacking or lifting a vehicle at the prescribed lift points, be certain that the jack and/or safety stands do not contact the exhaust system, brake pipes, cables, fuel lines or underbody. Such contact may result in damage or unsatisfactory vehicle performance.
