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 la‐
bel, you should determine the proper tire infla‐
tion pressure for those tires.) As an added safety
feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that il‐
luminates a low tire pressure telltale when one
or more of your tires is significantly under-in‐
flated. 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. Under-inflation also
reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping
ability. Please note that the TPMS is not a sub‐
stitute 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 illumination 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 prop‐
erly. The TPMS malfunction indicator is com‐
bined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will
flash for approximately one minute and then re‐
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.Seite 91SafetyControls91
Online Edition for Part no. 01 40 2 608 153 - 09 11 490

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.
1.Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.2.Check whether the vehicle is fitted with reg‐
ular tires or run-flat tires.
Run-flat tires, refer to page 227, are labeled
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.Seite 92ControlsSafety92
Online Edition for Part no. 01 40 2 608 153 - 09 11 490

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.
If an identification is not possible, please
contact the service center.2.Rectify the flat tire on the damaged wheel.
Run-flat tires
Maximum speed
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
If continuing to drive with a damaged tire:
1.Avoid sudden braking and steering maneu‐
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
correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize 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 depends
on how the vehicle is used during the trip, the
actual distance may be smaller or greater de‐
pending 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 prop‐
erties.◀
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 con‐
tinue driving, and contact your service center. ◀
Brake force display
The concept▷During normal brake application, the outer
brake lamps light up.▷During heavy brake application, the inner
brake lamps light up in addition.Seite 93SafetyControls93

Driving stability control systemsVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
Antilock Brake System ABS
ABS prevents locking of the wheels during brak‐
ing.
The vehicle remains steerable even during full
brake applications, thus increasing active
safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost. It thus helps to achieve the shortest
possible braking distance during full braking.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability
Control
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. Subjectto physical limits, DSC helps to keep the vehicle
on a steady course by reducing engine speed
and by applying brakes at 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.◀
Indicator/warning lamps The indicator lamp flashes: DSC con‐
trols the drive forces and brake forces.
The indicator lamp lights up: DSC has
failed.
Deactivating DSC: DSC OFF
When DSC is deactivated, driving stability is re‐
duced during acceleration and when driving in
bends.
To increase vehicle stability, activate DSC again
as soon as possible.
Deactivating DSC Press and hold the button, but not lon‐
ger than approx. 10 seconds, until the
indicator lamp for DSC lights up in the instru‐
ment cluster and DSC OFF is displayed.
The DSC system is switched off.
Activating DSC Press the button.
DSC OFF and the DSC indicator lamp
go out.Seite 94ControlsDriving stability control systems94
Online Edition for Part no. 01 40 2 608 153 - 09 11 490

Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
DTC Dynamic Traction
Control
The concept
The DTC system is a version of the DSC in which
forward momentum is optimized.
The system ensures maximum forward momen‐
tum on special road conditions, e.g., unplowed
snowy roads, but driving stability is limited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC un‐
der the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When rocking the vehicle or driving off in
deep snow or on loose surfaces.▷When driving with snow chains.
Deactivating/activating DTC Dynamic
Traction Control
Activating the Dynamic Traction Control DTC
provides maximum traction on loose ground.
Driving stability is limited during acceleration
and when driving in bends.
Activating DTC Press the button.
TRACTION is displayed in the instru‐
ment cluster and the indicator lamp for DSC
lights up.
Deactivating DTC
Press the button again.
TRACTION and the DSC indicator lamp
go out.
Performance Control
Performance Control enhances the agility of
your vehicle.
To enhance performance during sporty driving,
the rear wheel on the inside of the curve is
braked while the resulting braking effect is
largely compensated by engine intervention.
xDrive
xDrive is the all-wheel-drive system of your ve‐
hicle. Concerted action by the xDrive and DSC
further optimize traction and driving dynamics.
The xDrive all-wheel-drive system variably dis‐
tributes the drive forces to the front and rear
axles as demanded by the driving situation and
road surface.
HDC Hill Descent Control
The concept
HDC is a downhill driving assistant that auto‐
matically controls vehicle speed on steep down‐
hill gradients. Without the brakes being applied,
the vehicle moves at slightly more than twice
walking speed.
Hill Descent Control can be activated at speeds
below approx. 22 mph/35 km/h. When driving
downhill, the vehicle reduces its speed to ap‐
prox. twice walking speed and then keeps its
speed constant.
As long as there is active braking, the system is
on standby. The system does not brake the ve‐
hicle during this time.Seite 95Driving stability control systemsControls95
Online Edition for Part no. 01 40 2 608 153 - 09 11 490

Use HDC in low gears or in transmission position
D or R only.
Increasing or decreasing vehicle speed
Specify desired speed in the range from approx.
4 mph/6 km/h to approx. 15 mph/25 km/h using
the rocker switch of the cruise control on the
steering wheel. Vehicle speed can be changed
by lightly accelerating.▷Press up the rocker switch to the point of
resistance: the speed increases gradually.▷Press up the rocker switch past the point of
resistance: the speed increases while the
rocker switch is pressed.▷Press down the rocker switch to the point of
resistance: the speed decreases gradually.▷Press down the rocker switch past the point
of resistance: when driving forward, the
speed decreases to approx. 6 mph/10 km/h;
when reversing, the speed decreases to ap‐
prox. 4 mph/6 km/h.
Activating HDC
Press the button; the LED above the but‐
ton lights up.
Deactivating HDC
Press the button again and the LED goes
out. HDC is automatically deactivated
above approx. 37 mph/60 km/h.
Display in the instrument cluster The selected speed is displayed
in the speedometer.▷Green: the system is actively
braking the vehicle.▷Orange: the system is on
standby.
Malfunction
A message is displayed in the instrument clus‐
ter. HDC is not available, e.g., due to elevated
brake temperatures.
Dynamic Damping Control
The concept
This system reduces undesirable vehicle mo‐
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 two different programs.
The programs can be selected via Dynamic Driv‐
ing Control, refer to page 97.
SPORT
Consistently sporty control of the shock absorb‐
ers for greater driving agility.
NORMAL
Balanced control of the vehicle.
Seite 96ControlsDriving stability control systems96
Online Edition for Part no. 01 40 2 608 153 - 09 11 490

Variable sport steering
The variable sport steering increases the steer‐
ing angle of the front wheels at large steering
wheel angles, e.g., in tight curves or when park‐
ing. Steering becomes more direct.
It also varies the force required to turn the
wheels in accordance with the vehicle speed.
This results in a sporty steering response. In ad‐
dition, it becomes easier to steer during parking
and maneuvering.
Dynamic Driving Control
The concept
Dynamic Driving Control can be used to adjust
the driving dynamics of the vehicle. Several pro‐
grams are available for this purpose; they can be
activated using the two Dynamic Driving Control
buttons.
