Environmental note
Check the tyre pressure regularly,atl east
every 14 days.
You will find atable of tyre pressures for var-
ious operating conditionsont he inside of
your vehicle's fuel filler flap.
Operation with the emergency spare
wheel(Y page 351).
The table inside the fuel filler flap may state
tyre pressures for different load conditions.
These are defined in the table as different
numbers of passengers and amounts of lug-
gage. The actual number of seats may vary;
for more information,p lease refer to the vehi-
cle's registration documents.
If tyre sizes are not specified, the tyre pres-
sures stated on the tyre pressure information
label apply for all tyres approved for this vehi-
cle. If
at yre size precedes atyre pressure, the
following tyre pressure information is only
valid for that tyre size.
Use asuitable pressure gauge to check the
tyre pressure. The outer appearance of atyre
does not permit any reliablec onclusion about
the tyre pressure. On vehicles fitted with the
electronic tyre pressure monitor, the tyre pressure can be checked using the on-board
computer.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R
if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature, the
speed at which you are driving and the load
on the tyres, the tyre temperature and thus
the tyre pressure change by approximately
10 kPa per 10 †(0.1 bar/1.5 psi). Take this
into account whe nchecking the pressure of
warm tyres. Only correct the tyre pressure if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have anegative effect on handling charac-
teristics and thus the driving safety (e.g.
aquaplaning)
i The tyre pressure values given for low
loads are minimum values which offer you
good ride comfort characteristics.
However, you can also use the values given
for higher loads. These are permissible and
will not adversely affect the running of the
vehicle. Tyrep
ressur eloss warning system
Important safety notes While the vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in
atyre. If the speed
of rotation of awheel changes as aresult of
al oss of pressure, acorresponding warning 332

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.
