change as a result of variations in
temperature and loading.
●
●
Alloy wheels: replace the wheel bolt caps.
Plate wheels: replace the wheel hubcap
The wheel bolts 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.

page 170.
●
Check the tyre pressure of the newly moun-
ted tyre as soon as possible.
A directional tread pattern can be identified
by the arrows on the sidewall that point in the
direction of rotation. Always observe the di-
rection of rotation indicated when fitting the
wheel to guarantee optimum properties of
this type of tyres with regard to grip, noises,
wear and aquaplaning.
Removing and fitting a wheel
●
In vehicles fitted with a tyre pressure indica-
tor, adjust the pressure and store the reading
in the radio/Easy Connect system*
Change the wheel after loosening the wheel
bolts and raising the vehicle with the jack.

●
Have the tightening torque of the wheel
Taking off the wheel
bolts checked as soon as possible with a tor-
que wrench (it should be 140 Nm). Meanwhile,
drive carefully.
●
Unscrew the wheel bolts using the box
spanner and place them on a clean surface.
Take off the wheel.
If it is absolutely necessary to fit the spare
tyre* against the direction of rotation, drive
with care as this means the tyre does not of-
fer optimum driving properties. This is of par-
ticular importance when the road surface is
wet.
●
●
Have the flat tyre replaced as quickly as
possible.
Putting on the spare wheel
When fitting tyres with a compulsory rotation
direction, observe the instructions in
››› page 58.
To return to directional tread tires, replace the
punctured tyre as soon as possible and re-
store the obligatory direction of rotation of all
tyres.
Snow chains
●
Mount the wheel.
Screw on the wheel bolts in position and
tighten them loosely with a box spanner.
Use
●
Snow chains should only be used on the front
wheels.
●
Carefully lower the vehicle using the jack*.
