xDrive
xDrive is your BMW's four-wheel-drive system.
The combined efforts of xDrive and DSC help to
further optimize traction and driving dynamics.
The xDrive four-wheel-drive system distributes
driving power variably to the front and rear axles
depending on the drivin g situation and road
conditions.
Hill Descent Control HDC
HDC is a downhill driving assistant that controls
your speed on steep downhill gradients and
makes it even easier to control your BMW's
handling under these conditions. The vehicle
then moves slightly faster than double walking
speed without the driver needing to intervene.
HDC can be activated as long as you are driving
under approx. 20 mph or 35 km/h. When driving
downhill at a speed of under approx. 20 mph or
35 km/h, the vehicle's speed is automatically
reduced to slightly more than double walking
speed and maintained.
Increasing or de creasing speed
By accelerating or braking you can change this
speed within a range from approx. 3 to 15 mph,
approx. 5 to 25 km/h.
You can specify a target speed within the same
range by using the lever of the cruise control.

brake.
2. Release the brake and drive off without
delay.
The drive-off assistant holds the car in
place for approx. 2 seconds after the
brake is released. Drive off without delay after
releasing the brake. Ot herwise, the drive-off
assistant will no longer hold the car in place
after approx. 2 seconds an d the car will start to
roll backwards. <
Flat Tire Monitor FTM
The concept
The system does not measure the actual infla-
tion pressure in the tires.
The system detects a pressure loss in a tire by
comparing the rotational speeds of the individ-
ual 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 requirement
The system must have be en initialized while the
tire inflation pressure was correct; otherwise,
reliable signaling of a flat tire is not ensured.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reinitialize the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
A natural, steady pressure loss in all four tires is
not 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
> Performance-oriented style of driving: slip
in the drive wheels, hi gh lateral acceleration
> Snow chains are attached
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.
For operating principle refer to page 82.
1. Start the engine imme diately before pulling
away, but do not drive off yet.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until
the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Flat Tire Monitor.

Tire Pressure Monitor TPM
The concept
Check the inflation pressure
in the four installed
tires. The system notifies you if there is a signif-
icant loss of pressure in one or more tires.
Functional requirement
The system must have been reset while the
inflation pressure was co rrect; 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.
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
System limitations
Sudden serious tire damage caused by
external influences ca nnot be indicated in
advance.<
The system does not function correctly if it has
not been reset. For example, a flat tire may be
indicated even though the tire inflation pres-
sures are correct.
The system is inactive and cannot indicate a flat
tire:
> When a wheel without TPM electronics is
installed.
> Interference with TPM by other systems or
devices with the same transmission fre-
quency.
Resetting the system
Each time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed,
reset the system.
For operating principle refer to page 82.
1. Start the engine, but do not start driving.
2. Briefly press the button 1 in the turn signal/
high beam lever up or down repeatedly until the corresponding symbol and "RESET"
appear.
3. Press button 2 to confirm your choice of the
Tire Pressure Monitor. The following dis-
play appears:
4. Press button 2 for approx. 5 seconds, until
the small warning lamp lights up in yellow
and the following appears in the display:
5. Start driving.
After several minutes of driving time, the
adjusted inflation pressures will be adopted as
nominal values. The resetting process is com-
pleted automatically as you drive. The indicator
lamp goes out after the system reset is com-
pleted.

ControlsTechnology for driving comfort and safety
The trip can be interrupted at any time. When
driving resumes, resetting continues automati-
cally.
Message for low tire inflation pressure
The warning lamps light up in yellow
and red. In addition, a signal sounds.
> There is a flat tire or substantial loss of tire
pressure in the indicated wheel.
> The system was not reset after a wheel
change and thus issues a warning based on
the inflation pressure s initialized last.
Reduce speed and stop the vehicle with cau-
tion. Avoid sudden braking and steering
maneuvers. If the vehicle is not equipped with run-flat
tires, do not continue driving; continuing
to drive can result in serious accidents. <
When a low tire pressure is reported, the
Dynamic Stability Control DSC is activated.
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.
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.
3. At the next opportunity, check the inflation
pressure in all four tires.
If the inflation pressure is correct in all four
tires, then the Tire Pressure Monitor may
not have been reset. The system must then
be reset.
Possible driving distance with complete loss of
tire inflation pressure:
The distance it is possible to drive with a flat tire
depends on the load and the stress on the vehi-
cle while driving. With an average load, it may be possible to drive
for approx. 50 miles/80 km.
When driving with damaged tires, the handling
characteristics ch
ange, e.g. the vehicle will skid
sooner when braking, braking distances will be
longer, or self-steerin g response will change.
Adapt your driving style accordingly. Avoid
turning abruptly and driving over obstacles
such as curbs, potholes, etc.
Since the possible driving distance depends to
a considerable degree on the strain exerted on
the vehicle while driving, it can be shorter or,
with a gentle driving style, can also be longer,
depending on the speed, road condition, out-
side temperature, vehicle load, etc.
Drive cautiously an d do not exceed a
speed of 50 mph/80 km/h.
When there is a tire pressure loss, the handling
characteristics change , e.g. there will be
reduced directional stability during braking,
braking distances will be longer, and self-steer-
ing response will change. <
Vibrations or loud noises while driving can
indicate complete fa ilure of the tire.
Reduce your speed and bring the vehicle to a
stop; otherwise, tire components may become
detached, which could result in an accident. Do
not continue driving; instead, contact your
BMW center. <
Malfunction
The small warning lamp flashes in
yellow and then lights up continu-
ously; the large warning lamp lights
up in yellow. No punctures can be
detected.
Display in the follo wing situations:
> A wheel without TPM electronics has been
installed:
Have it checked by your BMW center.
> Malfunction
Have the system checked.
> Tire Pressure Monitor was unable to com-
plete the resetting process. Reset the sys-
tem again.
