To do this, check the air pressure in all four
tires, for instance using the tire pressure gage
of a flat tire kit.
If the tire inflation pressure in all four tires is
correct, the Tire Pressure Monitor may not
have been reset. In this case, perform the rej
set.
If identification of flat tire damage is not posj sible, please contact a dealerss service center
or another qualified service center or repair shop.2.Repair the flat tire, e.g., with a flat tire kit or bychanging the wheel.
Use of sealant, for instance from the flat tire kit,may damage the TPM wheel electronics. In this
case, have the electronics checked and replaced at the next opportunity.
Run-flattires
Safetyinformation
WARNING
Your vehicle handles differently with a run-flat with no or low inflation pressure; for instance, your lane stability when braking is reduced,braking distances are longer and the self-steerjing properties will change. There is a risk of an
accident.
Drive moderately and do not exceed a speed of 50 mph/80 km/h.
Maximumspeed
You may continue driving with a damaged tire at speeds up to 50 mph/80 km/h.
Continueddrivingwithaflattire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneuj
vers.2.Do not exceed a speed of 50 mph/80 km/h.3.Check the air pressure in all four tires at the
next opportunity.
If the tire inflation pressure in all four tires is

The distance for which it may be possible to
drive safely varies depending on how the vehicle
is loaded and used, e.g., speed, road conditions,
external temperature. The driving range may be
less but may also be more if an economical drivj ing style is used.
If the vehicle is loaded with an average weight
and used under favorable conditions, the disj
tance for which it may be safe to drive may be up to 50 miles/80 km.

Vehiclehandlingwithdamagedtires
Vehicles driven with a damaged tire will handle differently, potentially leading to conditions suchas the following:'xGreater likelihood of swerving off course.'xLonger braking distances.'xChanged self-steering properties.
Modify your driving style. Avoid abrupt steeringmaneuvers or driving over obstacles, for instancecurbs or potholes.
Finaltirefailure
Vibrations or loud noises while driving can indij cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of the
tire could come loose and cause an accident.
Do not continue driving. Contact a dealerss servj
ice center or another qualified service center or repair shop.
Systemlimits
Temperature
The tire inflation pressure depends on the tire's
temperature.
Driving or exposure to the sun will increase the
tire's temperature, thus increasing the tire inflaj
tion pressure.
The tire inflation pressure is reduced when the tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Suddentirepressureloss
The system cannot indicate sudden serious tire damage caused by external circumstances.
Failuretoperformareset
The system does not function properly if a reset has not been carried out, for instance a flat tire is
reported though tire inflation pressures are corj
rect.
Malfunction
The yellow warning light flashes and isthen illuminated continuously. A Check
Control message is displayed. It may not
be possible to identify tire pressure losses.
Examples and recommendations in the followingsituations:'xA wheel without TPM wheel electronics ismounted: have it checked by a dealerss servj
ice center or another qualified service center
or repair shop as needed.'xMalfunction: have system checked by a dealj erss service center or another qualified servjice center or repair shop.'xThe system was unable to complete the rejset. Perform a system reset again.'xInterference caused by systems or devices
with the same radio frequency: after leaving the area of the interference, the system autoj
matically becomes active again.
DeclarationaccordingtoNHTSA/
FMVSS138TirePressure
MonitoringSystem
Each tire, including the spare (if provided) should
be checked monthly when cold and inflated to the inflation pressure recommended by the vehijcle manufacturer on the vehicle placard or tire injflation pressure label. (If your vehicle has tires of
a different size than the size indicated on the vej
hicle placard or tire inflation pressure label, you
should determine the proper tire inflation presj sure for those tires.) As an added safety feature,your vehicle has been equipped with a tire presjsure monitoring system (TPMS) that illuminatesa low tire pressure telltale when one or more of
your tires is significantly under-inflated. Accordj
ingly, when the low tire pressure telltale illumij nates, 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 effij

Online Edition for Part no. 01402989120 - II/18

Page 153 of 312

ciency and tire tread life, and may affect the vehij
cle's handling and stopping ability. Please note that the TPMS is not a substitute 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 illuj
mination 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 properly. The TPMS malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxij
mately one minute and then remain continuously illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malj
function exists. When the malfunction indicator is
illuminated, the system may not be able to dej
tect 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. Alj
ways check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vej
hicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to
function properly.
FTMFlatTireMonitor
Concept
The system detects tire inflation pressure loss
on the basis of rotation speed differences bej
tween the individual wheels while driving.
In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of the corresponding wheel changes. The differj
ence will be detected and reported as a flat tire.
The system does not measure the actual inflaj
tion pressure in the tires.
Functionalrequirements
The following conditions must be met for the
system; otherwise, reliable flagging of a loss of tire inflation pressure is not assured:'xAfter a tire or wheel replacement, an initializaj
tion was performed with the correct tire inflaj
tion pressure.'xAfter the tire inflation pressure was adjusted
to a new value, an initialization was perj
formed.
Statusdisplay
The current status of the flat tire monitor can be
displayed, for instance whether the RPA is active.
Via iDrive:

The status is displayed.
Initializationrequired
An initialization must be performed in the followj
ing situations:
'xAfter the tire inflation pressure has been adj
justed.'xAfter a tire or wheel replacement.
Performinginitialization
When initializing, the set tire inflation pressures
serve as reference values in order to detect a flat tire. Initialization is started by confirming the tireinflation pressures.
Do not initialize the system when driving with snow chains.

Messages Generalinformation
When a flat tire is indicated, DSC Dynamic Staj bility Control is switched on, if needed.
Safetyinformation
WARNING
A damaged regular tire with low or missing tire inflation pressure impacts handling, such as
steering and braking response. Run-flat tires
can maintain limited stability. There is a risk of an accident. Do not continue driving if the vehij
cle is equipped with normal tires. Follow the inj
formation on run-flat tires and continued driving
with these tires.

sisted by a minor automatic braking intervention
in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
BrakinginterventionThe warning prompts the driver to react. During
a warning, the maximum braking force is used.
Prerequisite for the brake booster is sufficiently quick and hard stepping on the brake pedal. If
there is a risk of collision, the system may assist with braking. When the vehicle is traveling at a
low speed, the vehicle may come to a complete
stop.
Manual transmission: during a braking intervenj
tion up to a complete stop, the engine may be shut down.
The braking intervention occurs only if vehicle
stability has not been restricted, for instance by deactivating the DSC Dynamic Stability Control.
The driver may cancel the braking intervention
by stepping on the accelerator pedal or by acj
tively moving the steering wheel.
Object detection can be restricted. Follow the limitations of the detection range and functionalrestrictions.
Systemlimits
Safetyinformation
WARNING
The system can react not at all, too late, incorj
rectly, or without justification due to the system limits. There is a risk of accidents or risk ofdamage to property. Follow the information rejgarding the system limits and actively interveneif needed.
Detectionrange
The system's detection potential is limited.
Thus, a system reaction might not come or might come late.
E.g., the following situations may not be dej tected:'xSlow moving vehicles when you approach them at high speed.'xVehicles that suddenly swerve in front of you,
or sharply decelerating vehicles.'xVehicles with an unusual rear appearance.'xTwo-wheeled vehicles ahead of you.
Functionallimitations
The system may not be fully functional in the folj
lowing situations:
'xIn heavy fog, wet conditions, or snowfall.'xIn tight curves.'xIf the driving stability control systems are limj
ited or deactivated, for instance DSC OFF.'xIf, depending on the vehicle equipment verj sion, the field of view of the camera in the
mirror or the radar sensor is dirty or obscured.'xUp to 10 seconds after the start of the engine
via the Start/Stop button.'xDuring calibration of the camera immediately
after vehicle delivery.'xIf there are constant blinding effects because
of oncoming light, for instance from the sun low in the sky.
Warningsensitivity
The more sensitive the warning settings are, for
example the warning time, the more warnings are
displayed. Therefore, there may also be an exj
cess of premature or unjustified warnings and rej
actions.
