disappears.
The tyre pressure values stored at the last
restart will continue to be monitored. Checking the tyre pressure electroni-
cally*
The tyre pressure monitor only functions if
the correct wheel electronics are fitted to all
wheels. These monitor the pressure in all four
tyres, which you have set when restarting the
tyre pressure monitor. The monitor warns you
when the pressure drops in one or more of
the tyres. G
Risk of accident
The tyre pressure monitor does not warn
you of an incorrectly set tyre pressure. The
table on the inside of the fuel filler flap will
help you decide whether the tyre pressures
should be corrected.
The tyre pressure monitor is not able to
warn you of a sudden loss of pressure, e.g.
if the tyre is penetrated by a foreign object.
In the event of a sudden loss of pressure,
bring the vehicle to a halt by braking care-
fully. Do not make any sudden steering
movements when doing so. i
The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.
i If you are carrying a deflated tyre in the
vehicle, you may only reactivate the tyre
pressure monitor if:
R the deflated tyre is no longer in the vehi-
cle
R you have adjusted the tyre pressure cor-
rectly
Calling up the tyre pressure using the
on-board computer X
Make sure that the key is in position 2in
the ignition lock.
X Press the jork button to select the
tyre pressure function. The current tyre pressure for each wheel will
be displayed.
If the vehicle has been parked for longer than
20 minutes or you have not driven faster than
25 km/h since the vehicle was parked, the
following message appears:
Tyre pressure displayed only after
driving for a few minutes
i
The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge. The tyres pressures shown by the
on-board computer refer to those meas-
ured at sea level. The tyre pressure values
indicated by the on-board computer may
differ when the vehicle is at high altitude.
In this case, do not reduce the tyre pres-
sures.
Tyre pressure warning If the tyre pressure on one or more wheels
drops significantly, a message appears in the
multi-function display.
The tyre pressure of the affected wheel(s) will
be displayed in a red rectangle. You will also
hear a warning tone.Operation

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 2in
the ignition lock.
The standard display appears in the multi-
function display (Y page 125).
X Press the jork button to select the
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: Check current
tyre pressure?
X Press the æbutton.
The following message appears in the
multi-function display:
Tyre pressure monitor restarted
The tyre pressure monitor has stored the
pressure of the tyres as a new reference
value.
If you wish to cancel the restart:
X Press the çbutton. 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*. Operation

Winter driving
234
!
On vehicles fitted with a tyre pressure
monitor*, electronic components are loca-
ted in the wheel.
Tyre fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre. Winter driving
Points to remember
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter. Winter tyres
Use winter tyres at temperatures below +7 °
C and on snow or ice-covered roads. Only
then can the effect of the ABS, ESP ®
and
4MATIC* driving systems be ensured in win-
ter too.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with a tread depth of less than
4 mm must be replaced immediately. They
are no longer suitable for winter use, can
no longer provide sufficient grip. This could
cause you to lose control of your vehicle
and cause an accident.
Always observe the maximum permitted
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a lower maximum permitted speed than that of
the vehicle, affix an appropriate warning sign
in the driver's field of vision. This can be
obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
In such circumstances, you should also
restrict the maximum speed of the vehicle
using permanent Speedtronic 32
to the maxi-
mum permissible speed for winter tyres
(Y page 154).
Once you have fitted the winter tyres:
X Check the tyre pressures (Y page 229).
X Restart the tyre pressure moni-
tor* (Y page 232). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving sta-
bility will be impaired owing to unstable
cornering characteristics caused by the dif-
ferent tyres. You should therefore adapt
your driving style and drive carefully.
Have the spare wheel* replaced at the
nearest qualified specialist workshop
which has the necessary specialist knowl-
edge and tools to carry out the work
required. Mercedes-Benz recommends
32 Only available for certain countries. Operation
