Important information about wheel bolts
Factory-tted rims and wheel bolts are spe-
cially matched during construction. Therefore,
if dierent rims are tted, the correct wheel
bolts with the right length and heads must
be used. This ensures that wheels are tted
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 dierent 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.
Raise the vehicle

the vehicle.
•
Rest the jack (vehicles tools) on rm ground.
If necessary use a large, strong board or similar
support. If the surface is slippery (for example
tiles) place the jack on a rubber mat or similar
to prevent it from slipping

•
Look on the strut for the mark of the jack
support point (sunken area) closest to the
wheel to be changed ››› Fig. 201.
•
Turn the jack crank handle, located below
the strut support point, to raise it until the
tab
1
››› Fig. 202 is below the housing that
is provided.
•
Align the jack so that the tab
1
“grips”
onto the housing provided on the cross mem-
ber and the mobile base

is resting on the
ground. The base plate

should fall vertically
with respect to the support point

.
•
Continue turning the jack until the wheel is
slightly lifted o the ground.
