Malfunctions in the tire pressure monitoring
system
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indi-
cator is combined with the low tire pressure telltale.
When the system detects a malfunction, the telltale
will flash for approximately one minute and then re-
main continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as long
as the malfunction exists. When the malfunction in-
dicator is illuminated, the system may not be able to
detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, in-
cluding the installation of replacement or alternate
tires or wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires
or wheels on your vehicle to ensure that the re-
placement or alternate tires and wheels allow the
TPMS to continue to function properly.
Monitoring is interrupted in the following cases:
– If the tire pressure monitoring system is faulty
– If wheel sensors for the tire pressure monitoring
system are missing
– In the learning phase after the tire settings have
been updated
– After a wheel change without updating the tire
settings
– If the tire temperatures are too high

messages" on page 244.

For further information on the service status (avail-
ability dependent on country):

board Owner's Manual.
Retrieving the tire pressure
The individual tire pressures are only displayed
above a speed of approx 16 mph (25 km/h) or if the
tire is filled to at least 1.5 psi (0.1 bar). When the
vehicle is switched on after it has been stationary for
more than approx. 10 minutes, lines (-.-) are shown
instead of the tire pressures.
e Tire pressure e Current
The actual pressures are displayed for information
purposes only. The tire pressures change according
to the temperature.
e
Never change the tire pressures on the basis of
this display.
Displaying pressure deviation
Fig. 201: Example pressure difference
b b Vehicle is stationary.
e Tire pressure e Pressure difference
The pressure difference from the set pressure on the
relevant wheel is displayed. Example:
If the reading for the right rear tire is shown as
–0.1 bar , this tire needs to be inflated by
1.4 psi (0.1 bar). The tire temperature has already
been taken into account in the pressures shown.
e
You should only use the pressure difference from
the display or the corresponding tire pressure
warning to correct the tire pressure.
Setting the tires
Configuring settings for tire type, tire size and load
using the central display:

Please see chapter "Setting up the tire pressure
control system (TPM) in the central display" on
page 254.

trol system (TPM) in the central
display
WARNING
Incorrect settings
Tire pressure that is too low or too high destroys the
tire and wheel, extends the braking distance and
significantly increases the risk of an accident.
Although the Tire Pressure Monitoring System is
available, it is the driver's responsibility to ensure
that the tires are inflated to the correct tire pressure
and that the vehicle settings are correct. Incomplete
or incorrect settings can affect the output of warn-
ings and notices.
e
Adjust tire pressure to suit your tires and the
load.
e
Ensure that the settings in the TPMS menu cor-
respond to the tires fitted on the vehicle and the
current load of the vehicle (especially after a
