Important information about wheel bolts
Factory-fitted rims and wheel bolts are spe-
cially matched during construction. Therefore, if
different rims are fitted, the correct wheel bolts
with the right length and heads must be used.
This ensures that wheels are fitted securely and
that the brake system functions correctly.
In certain circumstances, you should not even
use wheel bolts from vehicles of the same
model.

WARNING
If the wheel bolts are not properly tightened,
they could come loose while driving and
cause an accident, serious injury and loss of
vehicle control.
●
Use only wheel bolts which correspond to
the rim in question.
●
Never use different wheel bolts.
●
Wheel bolts and threads should be clean,
free of oil and grease, and it should be possi-
ble to screw them easily.
●
To loosen and tighten wheel bolts, only
use the wheel wrench that came with the car
from the factory.
●
The wheel bolts should only be loosened
slightly (about one turn) before raising the
vehicle with the jack. Risk of accident!
●
Never apply grease or oil to wheel bolts or
to the wheel hub threads. Even if the bolts
have been tightened to the prescribed tor-
que, they could come loose while driving.
●
Never loosen the screwed joints of wheel
rims with bolted ring trims.
●
If wheel bolts are tightened below the
prescribed torque, the bolts and rims could
come loose while driving. If tightening torque
is too high, the wheel bolts or threads can be
damaged.
