car to loosen the wheel nuts.
Loosen the wheel nuts only about one turn
before raising the vehicle with the jack.
If the wheel bolt is very tight, carefully push
on the end of the wheel wrench with your
foot. Hold on to the vehicle for support and
take care not to slip during this operation.

Important information about wheel nuts
Factory-fitted rims and wheel nuts are spe-
cially matched during construction. There-
fore, if different rims are fitted, the correct
wheel nuts 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 nuts from vehicles of the same
model.
In wheels with full hubcaps, the anti-theft
locking bolt must be threaded onto positions

sition as reference

. Otherwise it will not be
possible to mount the hubcap.
WARNING
If the wheel nuts are not properly tight-
ened, they could come loose while driving
and cause an accident, serious injury and
loss of vehicle control.
● Use only wheel nuts which correspond to
the rim in question.
●
Never use different wheel nuts.
●
Wheel nuts and threads should be clean,
free of oil and grease, and it should be pos-
sible to screw them easily.
●
To loosen and tighten wheel nuts, only
use the wheel wrench that came with the
car from the factory.
●
The wheel nuts 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 nuts 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 nuts are tightened below the
prescribed torque, the bolts and rims could
come loose while driving. If tightening tor-
que is too high, the wheel nuts or threads
can be damaged.
