2003 Saab 9-3 Owner's Manual - Page 214

214 Car care • The jack should be stored correctly under the carpeting in the trunk. If it lies loose in the car, it could thrown forward and cause personal injury in the event of a crash or if the car rolls over. • Do not use the jack on a car other than your Saab 9-3. • Grit, salt and rust can clog the inner threads if the car has been driven for several years exclusively with alloy wheels. If steel wheels are now fitted, the bolt hole threads in the brake hubs should be cleaned before the thinner steel wheels are fitted. It may otherwise not be possible to achieve the correct clamping force, despite tightening the wheel bolts to the correct torque. Changing a wheel WARNING • The car jack is designed solely for use in changing a wheel or fitting snow chains. It must not be used to support the car during repair work or servicing. • Never crawl under a car that is supported only by a jack. • Special care must be taken if the car is on a slope - use wedge-shaped wheel chocks! • Position chocks, one ahead and one behind, the wheel that is diagonally opposite to the one to be changed. • Switch on the hazard warning lights if the car is on a road. • Apply the parking brake and leave the car in gear (1st or reverse). Automatic transmission: move the selector lever to the P position. • Ensure that everybody is out of the car before jacking it up. • Never start the engine while the car is jacked up. • If possible, make sure the jack is standing on a firm, level surface.
