First read and observe the introductory
information and safety warnings
Only the spanner delivered with the vehicle should be used to loosen the wheel bolts.
Only loosen the wheel bolts by approximately one turn before raising the vehicle with the vehicle jack.
If the wheel bolt is very tight, you may be able to loosen it by pushing down the end of the spanner carefully with your foot. Hold on to the car for support and take care not to slip.

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 the wheel bolts
The tightening torque for wheel bolts for steel and alloy wheels is 120 Nm. The tightening torque should be checked with a torque wrench immediately after changing a wheel.
If the wheel bolts are corroded and difficult to turn, they must be replaced 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.
