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.
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.
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.
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"
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.

The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Indication of a flat tire The warning lights come on in yellowand 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.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with
regular tires or run-flat tires.
Run-flat tires, refer to page 234, 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.
Actions in the event of a flat tire Normal tires
1.Identify the damaged tire.
Do this by checking the air pressure in all
four tires.
If the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not
have been initialized. In this case, initialize
the system.Seite 95SafetyControls95

Status indicator on the Control
Display
The tire and system status is indicated by the
color of the tires.
TPM takes into account that tire pressures
change while the vehicle is being driven.
All wheels are green
The system is active and issues warnings in
case of deviations from the tire inflation pres‐
sures stored last.
"TPM active" appears on the Control Display.
One wheel is yellow Flat tire or major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.

▷Flat tire or major drop in inflation pressure
in several tires.▷The system was not reset after a wheel
change and issues warnings in case of de‐
viations from the tire inflation pressures

tem is being reset.
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.
Status information
The status control display additionally shows
the current tire inflation pressures. It shows the actual values read; they may vary depending
on driving style or weather conditions.
Resetting the system
Reset the system after adjusting the tire infla‐
tion pressure and every time a tire or wheel is
changed.
1. Press the button. The start menu
opens.2."Vehicle Info"3."Vehicle status"4. "Reset"5.Start the engine, but do not start driving.6.Start the system reset with "Reset".7.Drive away. The tires are shown in gray and
"Resetting TPM..." is displayed.
After a short trip at over 30 km/h, the set tire
inflation pressures are adopted as target val‐
ues. The system reset is completed as you
drive, and can be interrupted at any time.
When driving resumes, the reset is continued
automatically. On the Control Display, the tires
are shown in green and "TPM active" is dis‐
played again.
If a flat tire is detected while the system is re‐
setting and determining the inflation pres‐
sures, all tires on the Control Display are dis‐
played in yellow. The message "Low tire!" is
shown.

Driving stability control systemsVehicle equipmentThis chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series. Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This

When using the features and systems descri‐

Antilock Brake System ABS ABS prevents locking of the wheels during
braking.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Electronic brake-force
distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
When you apply the brakes rapidly, this system automatically produces the maximum braking
force boost. It thus helps to achieve the short‐
est possible braking distance during full brak‐
ing. This system utilizes all of the benefits pro‐
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.Dynamic Stability Control
DSC
The concept DSC prevents traction loss in the driving
wheels when driving away and accelerating.
DSC also recognizes unstable vehicle condi‐
tions, such as fishtailing or nose-diving. Sub‐
ject to physical limits, DSC helps to keep the
vehicle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, even
with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀
Activating/deactivating DSC DSC can be deactivated/activated via the DSC
OFF program of the Dynamic Driving Control,
refer to page 102.
For better control The DSC indicator lamp flashes: DSC
is controlling the drive forces and brake
forces.
The DSC indicator lamp lights up: DSC has
failed.Seite 101Driving stability control systemsControls101
