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

Wheel and tire combination
Information on the correct wheel-tire combina‐
tion and rim versions for your vehicle can be ob‐
tained from your service center.
Incorrect wheel and tire combinations impair the
function of a variety of systems such as ABS or
DSC.
To maintain good handling and vehicle re‐
sponse, use only tires with a single tread con‐
figuration from a single manufacturer.
Following tire damage, have the original wheel
and tire combination remounted on the vehicle
as soon as possible.
Approved wheels and tires
The manufacturer of your vehicle recom‐
mends that you use only wheels and tires that
have been approved for your particular vehicle
model.
For example, despite having the same official
size ratings, variations can lead to body contact
and with it, the risk of severe accidents.
The manufacturer of your vehicle cannot evalu‐
ate non-approved wheels and tires to determine
if they are suited for use, and therefore cannot
ensure the operating safety of the vehicle if they
are mounted.◀
Recommended tire brands
For each tire size, the manufacturer of your ve‐
hicle recommends certain tire brands. These
can be identified by a star on the tire sidewall.
With proper use, these tires meet the highest
standards for safety and handling.
New tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac‐
tion potential until after an initial breaking-in pe‐
riod.
Drive conservatively for the first
200 miles/300 km.
Retreaded tires
The manufacturer of your vehicle does not rec‐
ommend the use of retreaded tires.
Retreaded tires
Possibly substantial variations in the de‐
sign and age of the tire casing structures can
limit service life and have a negative impact on
road safety.◀
Winter tires
The manufacturer of your vehicle recommends
winter tires for winter roads or at temperatures
below +45 ℉/+7 ℃.
Although so-called all-season M+S tires do pro‐
vide better winter traction than summer tires,
they do not provide the same level of perform‐
ance as winter tires.
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 theSeite 254MobilityWheels and tires254
Online Edition for Part no. 01 40 2 900 405 - 03 12 490
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 95.
Continued driving with a damaged tire, refer to
page 92.
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:▷225/55 R 17.▷245/45 R 18.▷245/40 R 19
Follow the chain manufacturer's instructions.
Make sure that the snow chains are always suf‐
ficiently tight. Retighten as needed according to
the chain manufacturer's instructions.
Do not initialize the Flat Tire Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
Do not initialize the Tire Pressure Monitor after
mounting snow chains, as doing so may result
in incorrect readings.
When driving with snow chains, briefly activate
Dynamic Traction Control if necessary.
Maximum speed with snow chains
Do not exceed a speed of 30 mph/50 km/h when
using snow chains.
