Note
The tyre pressures and temperatures are not
shown in the display when the vehicle is sta
tionary or during the initialisation phase. Hor
izontal dashes--.-- will appear instead of the
pressure and temperature figures.
(1) Loss of tyre pressure
Applies to: vehicles with tyre pressure monitoring system
If the indicator lamp
RE
appears, the tyre pres
sure on at least one of the wheels is too low or
new sensors have not yet been initialised.
Indicator lamp
[Bl
lights up after switching
on the ignition
The tyre pressure is too low compared with the
reference value.
... Adjust the pressure of the relevant tyre(s) at
the next opportunity and store the pressures
¢page 261.
Indicator lamp
[Bl
lights up during a journey
Wheels with new sensors have not yet been ini
tialised or the tyre pressure has reached a critical
level compared with the reference value.
... Avoid unnecessary braking and steering ma
noeuvres.
... Adapt your driving style to the prevailing condi
tions.
... As soon as you can do so safely, stop and check
the tyre(s).
... If it is possible to continue driving, you should
take the vehicle to a qualified workshop and
have the defective tyre(s) repaired or replaced
immediately.

Storing new tyre pressures
Applies to: vehicles with tyre pressure monitoring system
To enable the tyre pressure monitoring system
to work reliably, it is important to store the cor
rect pressure settings.
You should always store the tyre pressures if new
sensors are fitted or after changing the pressures
when carrying a different amount of passengers
or luggage.
... Before storing the new tyre pressures, check
that the current pressures on all four wheels
correspond to the specified values and adapt
the pressures to the current load
¢
page 256,
Fig. 222.
Only adjust and store the inflation
pressure of the tyres when they are at approxi
mately ambient temperature.
If
the tyre tem
peratures are higher than the ambient temper
ature, the inflation pressures should be in
creased by approx. 0.2 bar above the pressures
specified on the tyre pressure sticker.
... Switch on the ignition.
... Select the following on the infotainment sys
tem:
I
MENU
I
button>
Servicing
&
checks>
Tyre pressure loss indicator > Store tyre pres
sures> Yes, store now.
The tyre pressure moni
toring system will then measure the current
tyre pressures when you drive the vehicle and
store them as the new reference values .
... If the new tyre pressures do not appear on the
infotainment display, you will need to drive for
about 10 minutes so that the sensor signal
from the wheels can be received again .
During this initialisation phase,--.-- will be
shown on the pressure and temperature display
and some functions of the tyre pressure monitor
ing system will not be available. The system will
warn you only if the pressure of one or more tyres
is below the minimum reference pressure.
If the indicator lamp
RE
lights up and the mes
sage
Tyre pressure: wheel change detected.
Please check all tyres and store pressures in
MMI appears, the system has detected that the
sensor positions have changed because of a
wheel change or that new sensors have been fit-
ted. Store the new tyre pressures.
