Important information about the wheel bolts
The design of the wheel rims and wheel bolts is matched to the factory-fitted wheels. If different 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 works properly.
In certain circumstances, wheel bolts from a vehicle of the same model series may not be used.
Tightening torque for wheel bolts
The tightening torque for wheel bolts for steel and alloy wheels is 180 Nm(133 ft-lbs). The tightening torque should
be checked with a perfectly functioning torque spanner immediately after changing a wheel.
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 lubricate the wheel bolts or the threads of the wheel hub. This could cause them to loosen while the
vehicle is in motion, even if the required torque setting is used.
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 wheel bolt spanner supplied with 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 bolt and the threads in 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.
● Regularly check the tightening torque with a torque wrench. 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.
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.
● Use only wheel bolts that belong to the respective wheel rim.
● Never use different wheel bolts.
