if you have:
R changed the tyre pressure
R changed the wheels or tyres
R fitted new wheels or tyres
X Before restarting, make sure that the tyre
pressures are set properly on all four tyres
for the respective operating conditions.
The recommended tyre pressures can be
found in the table on the fuel filler flap.
The tyre pressure loss warning system can only give reliable warnings if you have set
the correct tyre pressure. If an incorrect
tyre pressure is set, these incorrect values
will be monitored.
X Observe the notes in the section on tyre
pressures (Y page 318).

The tyre pressure values stored at the last
restart will continue to be monitored. Tyre pressure monitor
General notes If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you if the
pressure drops in one or more of the tyres.
The tyre pressure monitor only functions if
the corresponding sensors are fitted to all
wheels.
Information on tyre pressures is shown in the multifunction display. After a few minutes of
driving, the current tyre pressure of each tyre
is shown in the Serv. Serv.menu of the multifunc-
tion display. Example: current tyre pressure display
For further information on displaying this
message, refer to the "Checking the tyre pres-
sure electronically" section (Y page 321).
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 318). Note that the correct tyre pres-
sure for the current operating situation must 320

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 and the yellow tyre pressure monitor warning
lamp comes on.
R If the Rectify tyre pressure
Rectify tyre pressure message
appears in the multifunction display, the
tyre pressure in at least one tyre is too low and must be corrected at the next oppor-
tunity.
R If the Check tyre(s)
Check tyre(s) message appears in
the multifunction display, the tyre pressure
in one or more tyres has dropped signifi-
cantly and the tyres must be checked.
R If the Warning tyre defect
Warning tyre defect message
appears in the multifunction display, the
tyre pressure in one or more tyres has drop- ped suddenly and the tyres must be
checked.
Observe the instructions and safety notes in
the display messages in the "Tyres" section
(Y page 243).
i If the wheel positions on the vehicle are
interchanged, 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 correct 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 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 318).
