Car care 247 Jacking points for floor jack Clean any rust or dirt from the contact surfaces between the wheel and brake disc. Do not wipe away the grease in the wheel hub. NOTICE • Do not overtighten the bolts using a impact wrench: not only can this damage the wheels but it can also make it impossible to undo the bolts using the wheel wrench in the car's toolkit. • When refitting a wheel cover, make sure that the valve protrudes through the marked recess in the wheel cover. 7 Retighten the wheel bolts after twenty or so miles. Tightening torque: Light-alloy wheels: 80 ft.lb. (110 Nm). Steel wheels: 80 ft.lb. (110 Nm). We advise against using wheels with large ventilation slots in winter, as the brake components are then more exposed to slush, road salt and grit. If you fit wheels of a different dimension, the speedometer can be reprogrammed to ensure it is as accurate as possible. Contact a Saab dealer. Driving with tire chains, see page 176
