7 Retouching 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 com-
ponents 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. We rec-
ommend that you contact a Saab dealer.

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.
Do not wipe away the grease in the wheel
hub.
Clean any rust or dirt from the contact sur-
faces between the wheel and brake disc.
