or 3 according to the position of the tyre valve 1 . The wheel cover can otherwise not be
fitted.
Tightening torque for wheel bolts
Specified tightening torque for wheel bolts for steel or alloy wheel rims:
—120 Nm.
If the wheel bolts are corroded and stiff, they must be renewed and the wheel hub threads
cleaned before the tightening torque is checked.
Never grease or oil the wheel bolts or the threads of the wheel hubs.
Have the tightening torque checked with a properly functioning torque wrench immediately after
changing a wheel.
WARNING
Incorrectly tightened wheel bolts can loosen while the vehicle is in motion and cause accidents,
serious injury, and loss of control of the vehicle.

The wheel bolts and threads of the wheel hubs must be clean, free from oil and grease, and
turn easily.
Always use the box spanner placed in the vehicle at the factory to loosen and tighten the
wheel bolts.
Only loosen the wheel bolts by approximately one turn before raising the vehicle with the
jack.
Never grease or oil the wheel bolts or the threads of the wheel hubs. This could cause them
to loosen while the vehicle is in motion, even if the required torque setting is used.
●
●
Never loosen the bolts on wheel rims with bolted-on rings.
If the tightening torque of the wheel bolts is too low, the wheel bolts and rims can loosen
while the vehicle is in motion. The wheel bolts and the threads could be damaged if the
tightening torque is too high. Check the tightening torque regularly using a torque wrench.
WARNING
The wrong wheel bolts can loosen while the vehicle is in motion and cause accidents, serious
injury, and loss of control of the vehicle.

Only use wheel bolts that belong to the respective wheel rim.
Never use different wheel bolts.
On vehicles with two-piece wheel bolts: use only two-piece wheel bolts.
