Restarting the tyre pressure monitor
In most cases, the tyre pressure monitor will
automatically detect the new reference val-
ues, e.g. if you have:
R
changed the tyre pressure
R
changed the wheels or tyres
R
fitted new wheels or tyres
If you wish to define the new reference values
manually:
X
Use the table on the inside of the fuel filler
flap to ensure that the tyre pressure is set
correctly in all four tyres for the current
operating conditions.
Also observe the notes in the section on
tyre pressures (
Y
page 229).
X
Make sure that the key is in position 2 in
the ignition lock.
The standard display appears in the multi-
function display (
Y
page 125).
X

Tyre pressure function
or wait until the
following message appears:
Tyre pressure displayed only after
driving for a few minutes
X
Press the reset button on the left of the
instrument cluster (
Y
page 243).
The following message appears in the
multi-function display:

button.
The following message appears in the
multi-function display:

value.
If you wish to cancel the restart:

Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only
if they have the same dimensions: for exam-
ple size, offset, etc.
After every wheel interchange/change,
have the tightening torque checked at a
qualified specialist workshop that has the
necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-related systems must be car-
ried out at a qualified specialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wheels may be interchanged every
5,000 km to 10,000 km depending on the
degree of tyre wear, provided that the vehicle
has the same size front and rear tyres. Do not
reverse the direction of tyre rotation.
The wear patterns on the front and rear tyres
differ depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. The front
tyres typically wear more on the shoulders
and the rear tyres in the centre.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system or the tyre pressure moni-
tor*.
