Online Edition for Part no. 01 40 2 927 905 - II/14
System limits
The system does not function properly if a reset
has not been carried out, e.g., a flat tire is re‐
ported even though the tire inflation pressures
are correct.
The tire pressure depends on the temperature
of the tire. If the tire temperature rises, e.g.,
due to driving or because of the heat of the
Sun, the tire inflation pressure increases also.
The tire pressure is reduced when the tire tem‐
perature falls again. This behavior may cause a
warning to be issued if temperatures fall very
sharply.
Malfunction The 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, such as a
compact wheel, is mounted: have the serv‐
ice 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 auto‐
matically 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 label, you should determine the
proper tire inflation pressure for those tires.) As
an added safety feature, your vehicle has been
equipped with a tire pressure monitoring sys‐
tem (TPMS) that illuminates a low tire pressure
telltale when one or more of your tires is signifi‐
cantly under-inflated. 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. Un‐
der-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han‐
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte‐
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-in‐
flation has not reached the level to trigger illu‐
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 approxi‐
mately one minute and then remain continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement 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.Seite 97SafetyCONTROLS97
Online Edition for Part no. 01 40 2 927 905 - II/14
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; other‐
wise, reliable signaling of a flat tire is not en‐
sured. Initialize the system after each correc‐
tion of the tire inflation pressure and after
every tire or wheel change.
Status display
The current status of the Flat Tire Monitor can
be displayed on the Control Display, e.g.,
whether or not the FTM is active.1."Vehicle Info"2."Vehicle status"3. "Flat Tire Monitor (FTM)"
The status is displayed.
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.
Do not initialize the system when driving with
snow chains.

Run-flat tires, refer to page 175, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents. ◀
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.
System limits Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance. ◀
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
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 wheels,
high lateral acceleration.▷When driving with snow chains.Seite 98CONTROLSSafety98

Collision warning with
City Braking function
The concept
The system can help to prevent accidents. If an
accident cannot be prevented, the system
helps to reduce the collision speed.
The system issues a warning if there is immi‐
nent danger of a collision and if so brakes inde‐
pendently.
The automatic braking intervention is done
with limited force and duration.
The system is controlled via a camera in the
base of the mirror.
The collision warning is available even if cruise
control has been deactivated.
When the vehicle is intentionally brought close to a vehicle, the collision warning is delayed to
avoid false warnings.
General information The system issues a two-phase warning of a
danger of collision with vehicles at speeds
above approx. 3 mph/5 km/h. The time of
these warnings may vary depending on the
current driving situation.
Up to approx. 35 mph/60 km/h a braking inter‐
vention occurs when appropriate.

Warning with braking function
Note Adapting your speed and driving style
The warning does not relieve the driver of
the responsibility to adapt his or her driving
speed and style to the traffic conditions. ◀
Display
If a collision with a vehicle detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.SymbolMeasureThe vehicle lights up red: prewarning.
Increase braking and distance.The vehicle flashes red and an acous‐
tic signal sounds: acute warning.
You are requested to intervene by
braking or making an evasive maneu‐
ver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During a warning, the maximum brak‐
ing force is used. A prerequisite for the brake
booster is a sufficiently fast and sufficiently
strong actuation of the brake pedal. In addi‐
tion, if there is a risk of collision, the system can
assist with a slight braking intervention. The in‐
tervention can bring a vehicle traveling at slow
speed to a complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if DSC
Dynamic Stability Control is switched on and
Dynamic Traction Control DTC is activated.
The braking intervention can be interrupted by
pressing on the accelerator pedal or by actively
moving the steering wheel.
Tow-starting and towing
When tow-starting and towing the vehi‐
cle, switch off the Intelligent Safety systems;
otherwise, improper behavior of the braking
function of individual systems could result in an
accident. ◀
System limits Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring. ◀
Detection range The system's detection capabilities are limited.
This may result in the warning not being issued
or being issued late.
For example, the following situations may not
be detected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.▷Pedestrians.
