Message when the system was not
reset
A Check Control message is displayed.
The system detected a wheel change but was
not reset.
Warnings regarding the current tire inflation
pressure are not reliable.
Check the tire inflation pressure and reset the
system.
Malfunction The yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire can be detected.
Display in the following situations:▷A wheel without TPM electronics is fitted:
have the service center check it if necessary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the sys‐
tem again.▷Disturbance by systems or devices with the
same radio frequency: after leaving the area
of the disturbance, the system automatically
becomes active again.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
System
Each tire, including the spare (if provided)
should be checked monthly when cold and in‐
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one
or more of your tires is significantly under-in‐
flated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate them
to the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub‐
stitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire
pressure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale. Your vehicle has also been
equipped with a TPMS malfunction indicator to
indicate when the system is not operating prop‐
erly. The TPMS malfunction indicator is com‐
bined 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 mal‐
function indicator 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, including 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.
FTM Flat Tire Monitor
The concept
The system does not measure the actual infla‐
tion pressure in the tires.
It detects a pressure loss in a tire by comparing
the rotational speeds of the individual wheels
while moving.Seite 93SafetyControls93

Adjusting the volume
Turn the knob during an announcement.
▷The volume remains constant even if the
volume of other audio sources is changed.▷The volume is stored for the remote control
currently in use.
Notes
Do not use the voice operation to initiate an
Emergency Request. In stressful situations, the
voice and vocal pitch can change. This can un‐
necessarily delay the establishment of a tele‐
phone connection.
Instead, use the SOS button, refer to
page 270, in the vicinity of the interior mirror.
Environmental conditions
▷Say the commands, numbers, and letters
smoothly and with normal volume, empha‐
sis, and speed.▷Always say commands in the language of
the system. The language for the mobilephone voice operation is preset and cannot
be changed in the Control Display.▷Keep the doors, windows, and glass sun‐
roof closed to prevent noise interference.▷Avoid making other noise in the vehicle
while speaking.
