xDrive
xDrive is the 4-wheel drive system of your
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing characteristics. The 4-wheel drive system
xDrive variably distributes the drive forces to
the front and rear axle depending on the driving
situation and prevailing road conditions.
Dynamic Performance Control*
The concept
Dynamic Performance Control optimizes the
handling characteristics of your BMW when
starting off, cornering, and during evasive
maneuvers. To achieve this, the system variably
distributes the drive torque of the rear axle to
the two rear wheels. This further increases the steering precision and tracking stability of your
vehicle.
Display
The Control Display shows how xDrive and
Dynamic Performance Control are distributing
the drive forces.
1."Vehicle Info"
2."Torque distribution"
The current distribution of drive forces is indi-
cated by arrows pointing to all four wheels.
The highlighted arrows show the drive forces
currently present. The longer an arrow is, the
greater the drive forces in the associated wheel.
The transparent arrows indicate the maximum
value the drive forces over the last 10 seconds.
Malfunction
Malfunctions are displayed via Check Control,
refer to page82.
HDC Hill Descent Control
The concept
HDC is a system for driving downhill in steep
terrain. This system reduces vehicle speed on
steep downhill gradients, thus allowing you to
maintain even better control of your BMW
under these conditions. The vehicle moves at
approximately walking speed without active
intervention from the driver.
HDC is available for activation at vehicle speeds
below approx. 22 mph/35 km/h. When driving
down steep hills with a speed below approx.
22 mph/35 km/h, the vehicle reduces speed
automatically down to approximately walking

Function requirements
The system must have been initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Initialize the system after every correction of the
tire inflation pressure and after every tire or
wheel change.
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
A natural, even pressure loss in all four tires
cannot be detected. Therefore, check the tire
inflation pressure regularly.
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
When you are driving with the compact wheel*
the Flat Tire Monitor is unable to function.
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
* or with the compact wheel*.
1."Vehicle Info"
2."Vehicle status"
3."Reset"
4.Start the engine – do not drive away.
5.Start the initialization using "Reset".
6.Start to drive.
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.<
Indication of a flat tire
The warning lamp lights up red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or a major loss in tire
inflation pressure.
Actions in the event of a flat tire
Run-flat tires
You can continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
If the vehicle is not equipped with run-flat
tires as provided at the factory, refer to
page249, do not continue driving. Continuing
to drive with a flat tire could cause severe acci-
dents.<

If you have deactivated DSC, it will be activated
automatically.
When driving with a damaged tire:
1.Avoid sudden braking and steering maneu-
vers.
2.Do not exceed a speed of 50 mph/80 km/h.
If the defective tire continues to lose pres-
sure, its position will be indicated to you on
the Control Display.
3.At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four
tires is correct, the Flat Tire Monitor
may not have been initialized. The system
must then be initialized.<
Possible driving distance with complete loss of
tire inflation pressure.
>With a light load:
1 to 2 persons without luggage:
Approx. 155 miles/250 km
>With a medium load:
2 persons, cargo area full, or
4 persons without luggage:
Approx. 95 miles/150 km
>With a full load:
4 or more persons, cargo area full:
Approx. 30 miles/50 km
Drive cautiously and do not exceed
speeds of 50 mph/80 km/h or else you
run the risk of causing an accident.
A loss of tire inflation pressure results in a
change in the handling characteristics, e.g.
reduced lane stability during braking, a longer
braking distance and altered self-steering prop-
erties.<
Vibrations or loud noises while driving can
indicate complete failure of the tire.
Reduce your speed and stop; otherwise, pieces
of the tire could come loose and cause an acci-
dent. Do not continue driving, and contact your
BMW Sports Activity Vehicle Center. The concept
Monitoring of the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Function requirements
The system must have been reset while the
inflation pressure was correct; otherwise, reli-
able signaling of a flat tire is not ensured.
Always use wheels with TPM electronics to
ensure that the system will operate properly.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
Sudden serious tire damage caused by
external influences cannot be indicated in
advance.<
The system does not operate correctly if it has
not been reset. For example, a flat tire may be
indicated despite correct tire inflation pres-
sures.
The system is inactive and cannot indicate a flat
tire:
>If a wheel without TPM electronics is
mounted, e.g. a compact wheel
*
>If the TPM is disturbed by other systems or
devices with the same radio frequency
Status display
The current status of the Tire Pressure Monitor
TPM can be displayed on the Control Display,
e.g. whether or not the TPM is active.

The concept
Your BMW is equipped with a full preparation
package mobile phone. After pairing a suitable
mobile phone with the vehicle once, you can
operate the mobile phone using iDrive, the but-
tons on the steering wheel, or voice com-
mands
*.
Once a mobile phone has been paired with your
vehicle, it is automatically recognized as soon
as it is inside the vehicle while the engine is run-
ning or the ignition is switched on. The pairing
data of up to four mobile phones can be stored
simultaneously. If several mobile phones are
detected simultaneously, the respective last
mobile phone paired can be operated via the
vehicle.
Using a phone in your vehicle
Using snap-in adapter*
The so-called snap-in adapter, a mobile phone
cradle, enables the battery to be charged and
the mobile phone to be connected to the exter-
nal antenna of your vehicle. This ensures
improved network reception and a consistent
voice reproduction quality. Ask your BMW
Sports Activity Vehicle Center which mobile
phones snap-in adapters are offered for.
For your safety
A car phone makes life more convenient in
many ways, and can even save lives in an emer-
gency. While you should consult your mobile
phone's separate operating instructions for a
detailed description of safety precautions and
information, we request that you direct your
particular attention to the following:
Only make entries when the traffic situa-
tion allows you to do so. Do not hold the
mobile phone in your hand while you are driving;
use the hands-free system instead. If you do
not observe this precaution, your being dis-tracted can endanger vehicle occupants and
other road users.<
Suitable mobile phones
Please ask your BMW Sports Activity Vehicle
Center which mobile phones with Bluetooth
interface are supported by the mobile phone
preparation package and which mobile phones
are compatible with the snap-in adapter. By vir-
tue of their particular software versions, these
mobile phones support the functions described
in this Owner's Manual. Malfunctions can occur
with other mobile phones.
Operating options
You can operate the mobile phone using:
>Buttons on the steering wheel, refer to
page10
>iDrive, refer to page16
>Voice commands
*, refer to page219
>Programmable memory buttons, refer to
page20
Avoid operating a mobile phone detected by
the vehicle with the keypad of the mobile
phone, otherwise malfunctions can occur.
