Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The curren ttyre pressur efor each wheel
will be displayed in the multifunction dis-
play.
If the vehicle was parked for longer than
20 minutes the Tyre pressures will be displayed after a few minutes of
driving message is shown.
After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. If a clear allocation of
the tyre pressure values to the individual
wheels is not possible, the message is shown
instead of the tyre pressure display .The tyre
pressures are already being monitored.
i If an emergency spare wheel is fitted, the
system may continue to show the tyre pres-
sure of the wheel that has been removed
for a few minutes. 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 signifi-
cant pressure loss on one or more tyres, a
warning message is shown in the multifunc-
tion display. Awarning tone also sounds and
the tyre pressure warning lamp lights up in
the instrument cluster.
Each tyre that is affected by a significant loss
of pressure is highlighted in the pressure dis-
play.
X If the Please correct tyre pressure message appears in the multifunction dis-
play, check the tyre pressure on all four
wheels and correct it if necessary.
i If the wheel positions on the vehicle are
interchanged, the tyre pressures may be
displayed for the wrong positions for a
short time. This is rectified after a few minutes of driving, and the tyre pressures
are displayed for the correct positions.
Restarting the tyre pressure monitor When you restar
tthe 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 referencev alues 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.
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 383).
X Make sure that the key is in position 2in
the ignition lock.
X Press the =or; button on the steer-
ing wheel to select the Serv. menu.
X Press the 9or: button to select
Tyre pressure .
X Press the abutton.
The multifunction display shows the cur-
rent tyre pressure for each tyre or the
Tyre pressures displayed after a few minutes of driving message.
X Press the :button.
The multifunction display shows the Use current pressure values as new ref‐
erence values message.
If you wish to confirm the restart:

After you have driven for a few minutes, the
system checks whether the current tyre
pressures are withi
nthe specified range.
The new tyre pressures are then accepted
as reference values and monitored.
If you wish to cancel the restart:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio type approval for the tyre pres-
sure monitor In certain countries, a radio type approval for
the tyre pressure monitor may be required.

G
WARNING
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.
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 389).
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 5000km to 10,000 km depending on
the degree of tyre wear. Maintain the direc-
tion of tyre rotation. 388
Changing
awheelWheels and tyres

Clean the contact surface
softhe 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 monitor. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation. Storing wheels
Store wheels that are not being used in a cool,
dry and preferably dark place. Protect the
tyres against oil, grease, petrol and diesel. Cleaning the wheels
G
WARNING
The water jet of circular-jet nozzles (dirt grind-
ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam-
aged tyres or chassis components replaced
immediately. Fitting

wheel you wish to change. Securing the vehicle on slight downhill gradients
(example: Saloon)
X On light downhill gradients: place
chocks or other suitable items in front of
the wheels of the front and rear axle. 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.
The following must be observed 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 suited for per-
forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, secure it from
rolling away by applying the parking brake
and inserting wheel chocks. Never disen-
gage 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, 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.O therwise, the
jac kw ill 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. 390
