MalfunctionThe yellow warning lamp flashes and
then lights up continuously. A Check
Control message is displayed. No flat
tire or loss of tire pressure 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 was unable to complete the reset. Re‐
set the system 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.
In the event of a pressure loss, the diameter and
therefore the rotational speed of the corre‐
sponding wheel change. This is detected and
reported as a flat tire.
Functional requirements
The system must have been initialized when the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction of the
tire inflation pressure and after every tire or
wheel change.Seite 105SafetyControls105

Maximum speed of winter tires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then display a corresponding sign in the field of
vision. You can obtain this sign from the tire spe‐
cialist or from your service center.
Maximum speed for winter tires
Do not exceed the maximum speed for the
winter tires; otherwise, tire damage and acci‐
dents can occur.◀
Run-flat tires
If you are already using run-flat tires, for your
own safety you should replace them only with
the same kind. No spare tire is available in the
case of a flat tire. Your service center will be glad
to advise you.
Rotating wheels between axles
The manufacturer of your vehicle advises
against swapping wheels between the front and
rear axles.
This can impair the handling characteristics.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible.
Always protect tires against all contact with oil,
grease and fuels.
Do not exceed the maximum tire inflation pres‐
sure indicated on the side wall of the tire.Run-flat tires
Label
RSC label on the tire sidewall.
The wheels are composed of special rims and
tires that are self-supporting, to a limited de‐
gree.
The support of the sidewall allows the tire to re‐
main drivable to a restricted degree in the event
of a pressure loss.
Continued driving with a damaged tire, refer to
page  107.
Continued driving with a damaged tire, refer to
page  104.
Changing run-flat tires
For your own safety, only use run-flat tires. No
spare tire is available in the case of a flat tire. Your
service center will be glad to advise you.
Snow chains
Fine-link snow chains
Only certain types of fine-link snow chains have
been tested by the manufacturer of your vehicle,
classified as road-safe and recommended.
Consult your service center for more informa‐
tion.
Use
Use only in pairs on the rear wheels, equipped
with the tires of the following size:

Squeeze the clips together and remove the bulb
holder.
Pull out the bulb and replace it.
Changing wheels
Notes
The vehicle equipment does not include a spare
tire.
When using run-flat tires or tire sealants, a tire
does not need to be changed immediately in the
event of pressure loss due to a flat tire.
The tools for changing wheels are available as
accessories from your service center.
Jacking points for the vehicle jack
The jacking points for the vehicle jack are lo‐
cated in the positions shown.
Vehicle battery
Maintenance
The battery is maintenance-free, i.e., the elec‐
trolyte will last for the life of the battery.
Your service center will be glad to advise you on
questions regarding the battery.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer;
otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery
registered on the vehicle by your service center
to ensure that all comfort functions are fully
available and that any Check Control messages
are no longer displayed.
Charging the battery
Note Do not plug chargers into the socket
Do not connect battery chargers to the
factory-installed sockets in the vehicle as this
may damage the battery.◀
General information
Make sure that the battery is always sufficiently
charged to guarantee that the battery remains
usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged peri‐
ods, longer than a month.Seite 218MobilityReplacing components218
