If the wheel bolt is very tight, you may be able to loosen it by pushing down
on the end of the wheel brace carefully with your foot. Hold on to the vehicle
for support and take care not to slip.
Loosening wheel bolts
● Fit the wheel brace as far as it will go over the wheel bolt
● Hold the wheel brace at the end and rotate the bolt approximately one
turn anticlockwise ⇒

Important information about wheel bolts
The wheel rims and bolts have been designed to be fitted to factory op-
tions. 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 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.

While driving
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 could be released while
driving leading to loss of vehicle control and serious damage.
● Only use wheel bolts which correspond to the wheel rims in question.
● Never use different wheel bolts.
● The bolts and threads should be clean, free of oil and grease and easy
to thread.
● To loosen and tighten the wheel bolts, always use the wheel brace
supplied with the vehicle.
● Loosen the wheel bolts only about one turn before raising the vehicle
with the jack.
● Never grease or lubricate wheel bolts or the wheel hub threads. Al-
though they have been tightened to the prescribed torque, they could
come loose while driving.
● Never loosen the bolted joints of wheel trims with bolted ring trims.
● If the wheel bolts are not tightened to the correct torque, they may
come loose while driving, and the bolts and rims may come out. If the
tightening torque is too high, the wheel bolts and threads can be dam-
aged.
