Warning messages of the tyre pressure
monitor If the tyre pressure monitor detects
asignifi-
cant pressure loss on one or more tyres, a
warning message is show ninthe multifunc-
tion display. Awarning tone also sounds and
th et yrep ressure warning lamp light supin
th ei nstrumen tcluster.
Eac htyret hatisa ffected by asignificant loss
of pressure is highlighted in th epressure dis-
play.
X If the Please correc ttyrep ressure message appear
sinthemultifunction dis-
play, check th etyrep ressure on all four
wheels and correct it if necessary.
i If th ewheel positions on th evehicle are
interchanged, th etyrep ressure smay be
displayed for th ewrongpositions for a
short time. This is rectified after afew
minute sofdriving,and th etyrep ressures
are displayed for th ecorrec tpositions.
Restarting th etyrep ressure 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 th etyrep ressure .However,
you can also define reference values man-
uallyasd escribed 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 331).
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 will be displayed after a few minutes of driving mes-
sage.
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:
X Press the abutton.
The Tyre press. monitor restarted message appears in the multifunction dis-
play.
After you have driven for
afew minutes, the
system checksw hether 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:
X Press the %button.
The tyre pressure values stored at the last
restart will continue to be monitored.
Radio typea pproval for the tyrep res-
sure monitor In certain countries,
aradio type approval for
the tyre pressure monitor may be required.

G
WARNING
Interchangin gthe 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 arisk of acci-
dent. Interchange front and rear wheels only if the
wheels and tyres are of the same dimensions.
! On vehicles fitted with atyre 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 aqualified spe-
cialist workshop.
Interchangin gthe front and rear wheels of
differing dimensions can render the general
operating permit invalid.
Observe the instructions and safety notes in
the "Fittin gawheel" section (Y page 337).
The wear pattern sonthe front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before aclear wear
pattern has formed on the tyres. Frontt yres
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.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time awheel
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 aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correc tdirection of rotation is
observed.
An arrow on the sidewal lofthe tyre indicates
its correc tdirection of rotation. 336

forming maintenance work under the vehi-
cle.
R avoid changing the wheel on uphilla nd
downhill slopes.
R before raising the vehicle, secure it from
rolling awaybya pplying 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 afirm, flat and
non-slip surface. On aloose surface, a
large, load-bearing underlay must be used.
On aslippery surface, anon-slip underlay
must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as ajack underlay.O therwise, the
