Position for jack, Saab 9-3 Viggen 8 Lower the car and tighten the wheel bolts to the correct torque in the sequence shown (opposite pairs). Tightening torque: Light-alloy wheels: 80 ft.lbs (110 Nm). Steel wheels: 80 ft.lbs (110 Nm). Do not overtighten the bolts using an 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. 9 Recheck the wheel bolts after a few miles. Tightening torque: Light-alloy wheels: 80 ft.lbs (110 Nm) Steel wheels: 80 ft.lbs (110 Nm) We advise against using wheels with open wheel covers in winter, as the brake components are then more exposed both to slush and to road salt and grit. Tire chains; see page 155. NOTE When refitting wheel covers (where applicable), make sure that the valve protrudes through the hole in the wheel cover. IB1174
