Important information about wheel bolts
The wheel
rims
and bo
lts have been de-
signed to be fitted to factory options. If differ-
ent rims are fitted, the correct wheel bolts
with the right length and correctly shaped
bolt heads must be used. This ensures that
wheels are fitted securely and that the brake
system functions correctly.
In some circumstances, wheel bolts from the
same model vehicle should not be used.
Wheel bolt tightening torque
The prescribed tightening torque for wheel
bolts for steel and alloy wheels is 110 Nm.
Have the tightening torque of the wheel bolts
checked as soon as possible with a reliable
torque wrench.
If wheel bolts are rusty and it is difficult to
tighten them, the threads should be replaced
and cleaned before checking the tightening
torque.
Never grease or lubricate wheel bolts or the
wheel hub threads. Although they have been
tightened to the prescribed torque, they
could come loose while driving.
WARNING
If the wheel bolts are not fitted correctly they
coul
d be released while driving leading to
loss of vehicle control and serious damage.
