Your vehicle was supplied with a jack for emergency road repairs. This jack is fine for changing a flat tire or other short term procedures not requiring you to go beneath the vehicle. If it is used in an emergency situation, carefully follow the instructions provided either with the jack or in your owner's manual. Do not attempt to use the jack on any portions of the vehicle other than specified by the vehicle manufacturer.
The standard jack utilizes special receptacles or locator pins found along the body sills (just behind the front or in front of the rear wheels). They accept the scissors jack supplied with the vehicle, for emergency road service only. The jack supplied with the vehicle should never be used for any service operation other then tire changing. NEVER get under the vehicle while it is supported only by a jack.
The service operations in this guide often require that one end or the other, or both, of the vehicle be raised and safely supported. The ideal method, of course, would be a hydraulic hoist. Since this is beyond both the resource and requirement of the do-it-yourselfer, a small hydraulic floor jack is recommended for most procedures which require access to the underbody of the vehicle. A floor jack can be used on various suspension and body-frame components (as detailed by the accompanying diagram).
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.
Whenever you plan to work under the vehicle, you must support it on jackstands or ramps. Never use cinder blocks or stacks of wood to support the vehicle, even if you're 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 other floor jack.
Always position a block of wood or small rubber pad on top of the jack or jackstand to protect the lifting point's finish when lifting or supporting the vehicle.
Small hydraulic, screw, or scissors jacks are satisfactory for raising the vehicle. Drive-on trestles or ramps are also a handy and safe way to both raise and support the vehicle. Be careful though, some ramps may be too steep to drive your vehicle onto without scraping the front bottom panels. Never support the vehicle on any suspension member (unless specifically instructed to do so by a repair manual) or by an underbody panel.
