Self-help
Taking off the wheel
●
Unscrew the wheel nuts using the box
spanner and pl
ace them on a cl
ean surf
ace
.
●
T
ake off the wheel.
Putting on the spare wheel
Check the direction of rotation of the tyre

●
Place the spare wheel or temporary spare
wheel into position.
●
Screw on the wheel nuts in position and
tighten them loosely with a box spanner.
●
To tighten the anti-theft locking wheel nuts
use the corresponding adaptor.
●
Carefully lower the vehicle using the jack*.
●
Use the wheel spanner to tighten all of the
wheel nuts clockwise. Tighten the bolts in di-
agonal pairs (not in a circle).
●
Put the caps, trim or full hubcap back on.
The wheel nuts should be clean and turn
easily. Before fitting the spare wheel, inspect
the wheel condition and hub mounting surfa-
ces. These surfaces must be clean before fit-
ting the wheel.
Tightening torque of the wheel nuts
The recommended tightening torque for
wheel nuts for steel and alloy wheels is
140 Nm. After changing a wheel, have the
tightening torque checked immediately with a
torque wrench that is working perfectly.
Before checking tightening torque, have any
rusty wheel nuts that are difficult to screw re-
placed and clean the wheel hub threads.
Never apply grease or oil to wheel nuts or to
the wheel hub threads. Even if the bolts have
been tightened to the prescribed torque, they
could come loose while driving.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed t

in only one direction. An arrow on the tyre
sidewall indicates the direction of rotation on
tyres with directional tread. Always observe
the indicated direction of rotation in order to
guarantee optimum grip and help avoid
aquaplaning, excessive noise and wear.
If the tyre is mounted in the opposite direction
of rotation, drive with extreme caution, as the
tyre is no longer being used correctly. This is
of particular importance when the road sur-
face is wet. Change the tyre as soon as pos-
sible or remount it with the correct direction
of rotation.
Works after changing a wheel
●
Alloy wheels: replace the wheel bolt caps.
●
Plate wheel
s: replace the wheel hubcap .
●
Return all tools to their proper storing loca-
tion.
●
If the replaced wheel does not fit in the
spare wheel housing, store it safely in the lug-
gage compartment

●
Check the tyre pressure of the newly moun-
ted tyre as soon as possible.
●
In vehicles fitted with a tyre pressure indica-
tor, adjust the pressure and st
ore it in memory

●
Have the tightening torque of the wheel
nuts checked as soon as possible with a tor-
que wrench
›››
page 45. Meanwhile, drive
carefully.
●
Have the flat tyre replaced as quickly as
possible.
