Wheels and tyres
Important information about wheel nuts
Factory-fitted rims and wheel nuts are specially
matched during construction. Therefore, if dif-
ferent 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.
On wheels with integral hubcaps, the anti-theft
wheel locking bolt must be screwed in the posi-
tions ›››Fig.247

, taking as reference
the position of the tyre valve
1
. Otherwise it
will not be possible to mount the hubcap.
WARNING
If the wheel nuts are not properly tightened,
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 dierent wheel nuts.
●
Wheel nuts 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 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 required torque,
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 re-
quired torque, the bolts and rims could come
loose while driving. If tightening torque is too
high, the wheel nuts or threads can be dam-
aged.

Fig.249 Crossbar: mounting the jack on the
vehicle.
●
Rest the jack (vehicles tools) on firm 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 crossbar for the mark of the
jack support point (sunken area) closest to the
wheel to be changed ›››Fig.248.
●
Turn the jack crank handle, located below
the crossbar support point, to raise it until the
tab
1
›››Fig.249 is below the housing that is
provided.
●
Align the jack so that the tab
1
“grips” onto
the housing provided on the cross member and
the mobile base
2
is resting on the ground. The
base plate

should fall vertically with respect
to the support point
1
.
●
Continue turning the jack until the wheel is
slightly lifted o the ground.
