Important safety notes
GWARNING
If wheels and tyres of the wrong size are used,
the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:
R designation
R type
When replacing tyres, make sure to fit the
correct:

GWARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop.
Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or that are not
being used correctly can impair operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations
Information on dimensions and types of
wheels and tyres for your vehicle can be
found ( Y page 329).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap
R under "Tyre pressure"
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop.
Operation
Information on driving
R Check the tyre pressures when the vehicle
is heavily laden and, if necessary, adjust.
R While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective,
reduce your speed immediately. Stop the
vehicle as soon as possible to check the

Restarting the tyre pressure monitor
When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the refer-
ence values for monitoring. In most cases, the
tyre pressure monitor will automatically
detect the new reference values after you
have changed the tyre pressure. However,
you can also define reference values man-
ually as described here. The tyre pressure
monitor then monitors the new tyre pressure
values.
XUse 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 319).XMake sure that the key is in position 2 in
the ignition lock.XPress the = or ; button on the steer-
ing wheel to select the Service menu.XPress the 9 or : button to select
Tyre pressure .XPress the a button.
The multifunction display shows the cur-
rent tyre pressure for the individual tyres or
the Tyre pressures will be dis‐
played after a few minutes of driv‐
ing message.XPress the : button.
The Use current pressures as new
reference values message appears in
the multifunction display.
If you wish to confirm the restart:
XPress the a button.
The Tyre press. monitor restarted
message appears in the multifunction dis-
play.
After you have driven for a few minutes, the
system checks whether the current tyre
pressures are within the specified range.The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
XPress the % button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Changing a wheel
Flat tyre
You can find information on what to do in the
event of flat tyre in the "Flat tyre" section
( Y page 298). Information on driving with
MOExtended tyres in the event of a flat tyre
can be found under "Breakdown assistance"
( Y page 298).
Vehicles with an emergency spare
wheel: in the event of a flat tyre, the emer-
gency spare wheel is fitted according to the
description under "Fitting a wheel"
( Y page 325).
Interchanging the wheels
GWARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tyres have different dimensions.
The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent.
Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! 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.
Only have tyres changed at a qualified spe-
cialist workshop.

Wheel and tyre combinations
General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle.
These are specially adapted to the control
systems, such as ABS or ESP ®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.Wheel and tyre combinations329Wheels and tyresZProCarManuals.com
