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.
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; otherwise,
reliable signaling of a flat tire is not ensured. In‐
itialize the system after each correction 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 can‐
not be detected. Therefore, check the tire infla‐
tion 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*.
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 inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.
Do not initialize the system when driving with
snow chains*.
1. "Vehicle Info"
2. "Vehicle status"
3. "Reset"
4. Start the engine - do not drive away.
5. Start the initialization with "Reset".
6. Drive away.
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 yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure. Seite 95

deep snow or on loose surfaces.
▷ When driving with snow chains.
Adaptive Drive*
The concept
Adaptive
Drive* includes the following systems:
▷ Dynamic Drive, refer to page 102
▷ Dynamic Damping Control, refer to
page 102
The system increases driving stability and driv‐
ing comfort.
Dynamic Drive*
The concept
Dynamic Drive reduces the lateral inclination of
the vehicle that occurs during rapid driving in
curves or during quick evasive maneuvers.
Driving stability and driving comfort are in‐
creased
under all driving conditions. The system
utilizes active stabilizer bars on the front and rear
axles that react immediately to all driving situa‐
tions.
Programs
The system offers two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 103.
SPORT
Sporty tuning for greater driving agility.
NORMAL
Comfort-oriented tuning for optimal comfort. Dynamic Damping Control*

tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort as required for the road surface and
driving style.
Programs
The system offers three different programs.
The
programs can be selected via Dynamic Driv‐
ing Control, refer to page 103.
SPORT
Consistently sporty control of the shock absorb‐
ers for greater driving agility.
NORMAL
Balanced tuning between the COMFORT and
SPORT programs.
COMFORT
Comfort-oriented tuning of the shock absorbers
for optimal traveling comfort.
Integral Active Steering*
The concept
Integral Active Steering is a combination of Ac‐
tive Steering and rear axle steering.
Active Steering varies the steering angle of the
wheels in relation to the steering wheel move‐
ment as a function of the speed.
At speeds up to approx. 37 mph/60 km/h, e.g.,
in curves, the steering angle is increased, i.e.,
steering becomes more direct.
The rear axle steering acts to increase maneu‐
verability by turning the rear wheels slightly in a
direction opposite to the front wheels.
At higher speeds, the steering angle is increas‐
ingly reduced.

102 Online Edition for Part no. 01 40 2 606 521 - 03 11 490
Driving stability control systems
The rear wheels are turned to the same angle as
the front wheels.
In
critical situations, Integral Active Steering can
specifically steer the front and rear wheels to
stabilize the vehicle before the driver intervenes,
e.g., when braking where road conditions differ
on the left and right sides of the vehicle.
Initializing
In rare cases, it may become necessary to initi‐
alize the Integral Active Steering.
The warning lamp lights up. A Check
Control message is displayed.
1. With the engine running, turn the steering
wheel
all the way to the left and right several
times in a uniform manner until the warning
lamp disappears.
2. Have the system checked if the warning
lamp
does not go out after moving the steer‐
ing wheel approx. 6 times or if the steering
wheel is at an angle.
Using snow chains
Ensure
that the rear axle steering is deactivated
when using snow chains, refer to page 235.
Programs
