Important safety notes
It is the driver's responsibility to set the tyre
pressure to the recommended cold tyre pres-
sure suitable for the operating situation
(Y page 458). Note that the correct tyre pres-
sure for the current operating situation must
first be taught-in to the tyre pressure monitor. If there is a substantial loss of pressure, the
warning threshold for the warning message is aligned to the reference values taught-in.
Restart the tyre pressure monitor after
adjusting to the cold tyre pressure
(Y page 462). The current pressures are
saved as new reference values. This will
ensure that a warning message will only
appear if the tyre pressure drops significantly.
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. Observe
the notes on the recommended tyre pressure
(Y page 458).
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 carefully. Avoid
abrupt steering manoeuvres.
The tyre pressure monitor has a yellow warn-
ing lamp in the instrument cluster for indicat- ing a pressure loss or malfunction. Dependingon how the warning lamp flashes or lights up,
a tyre pressure that is too low or a malfunc-
tion in the tyre pressure monitor is indicated:
R if the warning lamp is lit continuously, the
tyre pressure on one or more tyres is sig-
nificantly too low. The tyre pressure moni-
tor is not malfunctioning.
R if the warning lamp flashes for around a
minute and then remains lit constantly, the
tyre pressure monitor is malfunctioning.
In addition to the warning lamp, a message
appears in the multifunction display. Observe
the information on display messages
(Y page 367).
It may take up to ten minutes for a malfunc-
tion of the tyre pressure monitor to be indi-
cated. A malfunction will be indicated by the tyre pressure warning lamp flashing for
approximately one minute and then remain-
ing lit. When the fault has been rectified, the
tyre pressure warning lamp goes out after you
have driven for a few minutes.
The tyre pressure values indicated by the on- board computer may differ from those meas-
ured at a filling station using a pressure
gauge. The tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pressure
values indicated by a pressure gauge are
higher than those shown by the on-board
computer. In this case, do not reduce the tyre
pressures.
The operation of the tyre pressure monitor
can be affected by interference from radio
transmitting equipment (e.g. radio head-
phones, two-way radios) that may be being
operated in or near the vehicle.

If an emergency spare wheel is fitted, for a
few minutes the system may continue to
show the tyre pressure of the wheel that has
been removed. If this occurs, note that the
value displayed for the position where the
spare wheel is fitted is not the same as the
current tyre pressure of the emergency spare wheel.
Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects a pres-
sure loss in one or more tyres, a warning mes-
sage is shown in the multifunction display.
The yellow tyre pressure warning lamp then
lights up.
R If the Please correct tyre pressure

message appears in the multifunction dis-
play, the tyre pressure in at least one tyre is
too low. The tyre pressure must be correc-
ted when the opportunity arises.
R If the Check tyre(s)
Check tyre(s) message appears in
the multifunction display, the tyre pressure in at least one tyre has dropped signifi-
cantly. The tyres must be checked.
R If the Warning tyre defect Warning tyre defect message
appears in the multifunction display, the
tyre pressure in at least one tyre has drop- ped suddenly. The tyres must be checked.
Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 367).
If the wheel positions on the vehicle are inter-
changed, the tyre pressures may be displayed
for the wrong positions for a short time. After a few minutes of driving, this is rectified and
the tyre pressures are displayed for the cor-
rect positions.
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 set reference values manually as described here. The tyre pressure monitor
then monitors the new tyre pressure values.
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 458).

Tyre pressureWheels and tyres

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.
Interchanging the front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fitting a wheel" section (Y page 464).
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. Front tyres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size front and rear wheels, you can interchange the wheels
every 5,000 to 10,000 km depending on the
degree of tyre wear. Ensure the direction of
rotation is maintained.
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 (Y page 460) or the tyre pres-
sure monitor (Y page 462). Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk of aquaplaning. These advantages can only begained if the tyres are fitted corresponding to
the direction of rotation.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. Storing wheels
Store wheels in a cool, dry and preferably
dark place if they are not being used. Protect the tyres against oil, grease, petrol and diesel. Fitting a wheel

i Apart from some country-specific var-
iants, vehicles are not equipped with tyre-
changing tools. Some tools for changing a
wheel are specific to the vehicle. For more information on which tools are required to
perform a wheel change on your vehicle,
consult a qualified specialist workshop.
Necessary tyre-changing tools may
include, for example:
R Jack
R Wheel chock
R Wheel wrench
R Centring pin 464
Changing a wheelWheels and tyres

Securing the vehicle against rolling
away
If your vehicle is equipped with a wheel chock,
it can be found in the tyre-change tool kit
(Y page 432).
The folding wheel chock is an additional
securing measure to safeguard the vehicle
from rolling away, for example when changing
a wheel.
X Fold both plates upwards :.
X Fold out lower plate ;.
X Guide the lugs on the lower plate fully into
the openings in base plate =.X
Place chocks or other suitable items under
the front and rear of the wheel that is diag-
onally opposite the wheel you wish to
change.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the
vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not permissible to
use it to perform maintenance work under
the vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake
and positioning wheel chocks. Do not
release the parking brake while the vehicle
is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised. Changing a wheel

Turn the crank of the jack anti-clockwise
until the vehicle is once again standing
firmly on the ground.
X Place the jack to one side.
X Tighten the wheel bolts evenly in a cross-
wise pattern in the sequence indicated ( :
to A). The specified tightening torque is
130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre-
change tool kit in the load compartment
again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 458).
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system or the tyre pressure monitor cannot
function reliably. Only restart the tyre pres-
sure loss warning system or tyre pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with a tyre pressure monitor: all
fitted wheels must be equipped with func-
tioning sensors. 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.
Overview of abbreviations used in the follow- ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended tyre pressures for various
operating conditions can be found in the tyre pressure table on the fuel filler flap. Further
information on tyre pressure (Y page 458).468
