Taking off the wheel
●
Using the hexagonal socket in the wheel
brace
›››
Fig. 42, unscrew the slackened
wheel nuts and place them on a clean sur-
face.
●
Unscrew the wheel nuts using the box
spanner and place them on a clean surface.
●

Putting on the spare wheel
Check the direction of rotation of the tyre
›››
page 48.
●
Place the spare wheel or temporary spare
wheel into position.
●
Replace the wheel nuts and tighten slightly
using the hexagonal socket on the end of the
wheel brace.
●
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).
●
Fit the wheel caps
›››
page 45.
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.
WARNING
The hexagonal socket in the wheel brace
should be used for turning wheel nuts only.
Do not use it to loosen or tighten the wheel
nuts.
Tyres with directional tread pattern
Tyres with directional tread pattern have
been designed t
o oper
at
e best when r
ot
ating
in only one dir
ection. An arr
ow 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.
