Detected child seatsThe system generally detects children seated
in a child seat, especially in the child seats that
were required by NHTSA when the vehicle was
manufactured. After installing a child seat,
make sure that the indicator lamp for the front
passenger airbags lights up. This indicates that the child seat has been detected and the
front passenger airbags are not activated.
Strength of the driver's and front
passenger airbag
The strength with which the driver's and front
passenger airbags are triggered depends on
the position of the driver's and front passenger
seats.
To maintain the accuracy of this function over
the long-term, calibrate the front seats when a
corresponding message appears on the Con‐
trol Display.
Calibrating the front seats A corresponding message appears on the
Control Display.1.Move the respective seat forward all the
way.2.Move the respective seat forward again. It
moves forward briefly.3.Readjust the seat to the desired position.
The calibration procedure is completed when
the message on the Control Display disap‐
pears.
If the message continues to be displayed, re‐
peat the calibration.
If the message does not disappear after a re‐
peat calibration, have the system checked as
soon as possible.
Unobstructed area of movement
Ensure that the area of movement of the
seats is unobstructed to avoid personal injury
or damage to objects.◀
Tire Pressure Monitor TPM
The concept The system monitors tire pressure in the four
mounted tires. The system warns you if there
is a significant loss of pressure in one or more
tires. For this purpose, sensors in the tire
valves measure the tire inflation pressure.
Hints Tire damage due to external factors
Sudden tire damage caused by external
influences cannot be indicated in advance.◀
Pay attention to the other information and indi‐
cations under Tire inflation pressure, refer to
page 187, as well when using the system.
Functional requirements
The system must have been reset with the
correct tire inflation pressure; otherwise, relia‐
ble signaling of tire pressure loss is not en‐
sured.
Reset the system again after each correction
of the tire inflation pressure and after every tire
or wheel change.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Status display The current status of the Tire Pressure Moni‐
tor TPM can be displayed on the Control Dis‐
play, e.g., whether or not the TPM is active.1."Vehicle Info"2."Vehicle status"3. "Tire Pressure Monitor (TPM)"

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.
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 103SafetyControls103

If an identification is not possible, please
contact the service center.2.Rectify the flat tire.
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 de‐
pends on how the vehicle is used during the
trip, the actual distance may be smaller or
greater depending 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
properties.◀
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 continue driving, and contact your service
center.◀
Intelligent Safety
The concept Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more of the
following systems, which can help to avoid an
imminent collision. These systems are active
automatically every time the engine is started
using the Start/Stop button:▷Collision warning, refer to page 105.▷Pedestrian warning, refer to page 110.
Note
Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise an
accident is still possible despite all warnings.◀

Collision warning
Depending on how the equipment is equipped,
the collision warning system consists of one of
the two systems:▷Collision warning with City Braking func‐
tion, refer to page 105;▷Collision warning with braking function, re‐
fer to page 108
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.

Indicator/warning lamps
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
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 mo‐
mentum on special road conditions, e.g., unp‐
lowed snowy roads, but driving stability is lim‐
ited.
It is therefore necessary to drive with appropri‐
ate caution.
You may find it useful to briefly activate DTC
under 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
OFF lights up.
Deactivating DTC
Press the button again.
TRACTION and the DSC OFF indica‐
tor lamp go out.
Above 31 mph/50 km/h DTC is automatically
deactivated.
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.
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 several different programs.
The programs can be selected via the Driving
Dynamics Control, refer to page 118.

COMFORT/ECO PROBalanced control of the vehicle.
Variable sport steering The variable sport steering increases the
steering angle of the front wheels at large
steering wheel angles, e.g., in tight curves or
when parking. 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
addition, it becomes easier to steer during
parking and maneuvering.
Driving Dynamics Control The conceptThe Driving Dynamics Control can be used to
adjust the certain characteristics of the vehicle.
