Sudden serious tire damage caused by
external influences cannot be indicated in ad‐

A natural, even pressure loss in all four tires
cannot be detected.
The system could be delayed or malfunction in
the following situations:▷When the system has not been initialized.▷When driving on a snowy or slippery road
surface.▷Sporty driving style: slip in the drive

Initialization
The initialization process adopts the set infla‐
tion tire pressures as reference values for the
detection of a flat tire. Initialization is started by
confirming the inflation pressures.

Indication of a flat tire The warning lamps come on in yellow
and red. A message appears on the
Control Display. In addition, a signal
sounds.
There is a flat tire or a major loss in tire inflation
pressure.

one or more tires. Sensors in the tire valves
measure the tire pressure.
Notes Tire damage caused by external influen‐
ces
Sudden tire damage caused by external influ‐
ences cannot be indicated in advance.◀
To operate the system, also note the additional
information and instructions contained under
Tire inflation pressure, refer to page 226.
Functional requirement The system must have been reset while the in‐
flation pressure was correct; otherwise, reliable
signaling of pressure loss is not ensured.
Reset the system after adjusting the tire infla‐
tion pressure and after changing a tire or
wheel.
Always use wheels with TPM electronics to
ensure that the system will operate properly.

A message appears on the Control Display.
The wheels are gray The system cannot detect a flat tire.
Possible reasons for this:
▷TPM is being reset.▷Disturbance by systems or devices with
the same radio frequency.▷Malfunction.
Resetting the system
Reset the system after adjusting the tire infla‐
tion pressure and every time a tire or wheel is
changed.

opens.2."Vehicle Info"3."Vehicle status"Seite 95SafetyControls95
Online Edition for Part no. 01 40 2 957 403 - X/14

If the tire inflation pressure in all four tires
is correct, the Tire Pressure Monitor may
not have been reset. Reset the system.
Possible driving distance with complete loss of
tire inflation pressure:
The possible driving distance after a loss of tire
inflation pressure depends on the cargo load
and the driving style and conditions.
For a vehicle containing an average load, the
possible driving distance is approx.
50 miles/80 km.
When the vehicle is driven with a damaged tire,
its handling characteristics change, e.g., re‐
duced lane stability during braking, a longer
braking distance, and altered self-steering
properties. Adjust your driving style accord‐
ingly. Avoid abrupt steering maneuvers or driv‐
ing over obstacles, e. g., curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending on the driving speed, road
conditions, external temperature, cargo load,
etc.
Continued driving with a flat tire
Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g., re‐
duced lane stability during braking, a longer
braking distance and altered self-steering
properties.◀
Final tire failure
Vibrations or loud noises while driving
can indicate the final failure of the tire. Reduce
speed and stop; otherwise, pieces of the tire
could come loose and cause an accident. Do
not continue driving, and contact your service
center.◀
Message when not reset
The warning light lights up yellow. A
Check Control message is displayed.
The system may not have been reset
although a wheel was changed.
Check the tire inflation pressure and reset the
system, refer to page 95.
System limits
The system does not function properly if it has
not been reset, e.g., it may identify a tire as flat
in spite of the fact that the tire is filled to the
correct inflation pressure.
The tire pressure depends on the temperature
of the tire. An increase in the tire temperature,
e.g., while driving or due to sunlight, increases
the tire inflation pressure. The tire pressure
decreases when the tire temperature drops. In
case of severe temperature drops, this behav‐ ior may lead to a warning on account of the de‐
fined warning limits.
Malfunction The small warning light flashes in yel‐
low and then lights up continuously;
the larger warning light comes on in
yellow. On the Control Display, the
tires are shown in gray and a message ap‐
pears. 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 neces‐
sary.▷Malfunction: have the system checked by
your service center.▷TPM could not be fully reset. Reset the
system again.

over.
Recirculated air mode If the air outside the car has an un‐
pleasant odor or contains pollu‐

The recirculated air mode can also be acti‐
vated/deactivated, refer to page 12, via a but‐
ton on the steering wheel.
