Cruise control*
The vehicle maintains and stores the speed that
you set at speeds greater than approx. 20 mph/
30 km/h.
You can use cruise control whenever the sys-
tem is active while the engine is running.
Do not use the cruise control under unfa-
vorable conditions that do not permit a
constant speed, e.g. when driving on winding
roads or in heavy traffic or when negotiating
poor road conditions such as snow, rain, ice, or
a loose road surface. Otherwise, you could lose
control of the vehicle and cause an accident.<
Indicator lamp
The indicator lamp lights up green: sys-
tem ready for operation using the but-
tons on the steering wheel.
Activating system
With ignition key in position 2 or higher:
Press button on steering wheel; the indicator
lamp in the instrument cluster comes on. The
cruise control mode is enabled.
Deactivating system
Press the button repeatedly until the indicator
lamp in the instrument cluster goes out.
The cruise control is also deactivated when the
ignition key is turned to position 0. The speed
stored in the memory is deleted in the process.
Maintaining speed, storing, and
accelerating
Briefly press + button:
The system maintains and stores the current
vehicle speed. Each additional touch of the but-ton increases the speed by approx. 1 mph/
1km/h.
Press and hold + button:
The vehicle accelerates without pressure on
the accelerator pedal. When you release the
button, the system maintains and stores the
current speed.
If the braking action of the engine is insufficient
on a downhill stretch, then the set vehicle can
exceed the set speed. Speed can drop on uphill
grades if the engine output is insufficient.
Decelerating
Briefly press – button:
Each press of the button decreases the vehi-
cle's speed by roughly 1 mph/1 km/h, provided
that you have already activated the cruise con-
trol.
Press and hold – button:
With the cruise control active, the system auto-
matically reduces the fuel supply to slow the
vehicle. When you release the button, the sys-
tem maintains and stores the current speed.
Interrupting cruise control
When the system is activated, press the button.
The indicator lamp stays on. You can use the
cruise control again whenever required by
requesting the speed that was stored last.
In addition, the system is automatically inter-
rupted in response to the following conditions:
>When you apply pressure to the brake pedal
>When you apply pressure to the clutch
pedal or when you move the automatic
transmission selector lever from D to N
>If you exceed or fall below the set speed for
an extended period, by pressing the accel-
erator, for example
>When DSC is activated

Malfunction
The LED in the button flashes and a short con-
tinuous tone sounds. PDC is malfunctioning.
Switch off PDC. Have the system checked.
To prevent this problem, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively.
When using high-pressure washers, do not
spray sensors for long periods and keep the
sprayer at least 4 in/10 cm away from the sen-
sors.
System limits
Even with PDC, final responsibility for
estimating the distance between the
vehicle and any obstructions always remains
with the driver. Even when sensors are involved,
there is a blind spot in which objects cannot be
detected. The system is also subject to the
physical limits that apply to all forms of ultra-
sonic measurement, such as those encoun-
tered with tow bars and trailer couplings, or thin
and wedge-shaped objects. Low objects
already displayed, e.g. curb edges, can come
into the blind spot of the sensors before or after
a continuous tone sounds. The system may fail
to detect higher obstacles such as projections
from walls.
Loud sources of sound, inside and outside the
vehicle, could drown out the PDC signal tone.<
Driving stability control
systems
Your BMW is equipped with an extended array
of systems designed to enhance and maintain
vehicle stability even under unfavorable driving
conditions.
ABS Antilock Brake System
ABS prevents the wheels from locking during
braking. Safe steering response is maintained
even during full braking. This results in an
increase in the active safety.
ABS is operational every time you start the
engine. Safe braking, refer to page81.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
Brake assistant
When the brake pedal is depressed quickly, this
system automatically generates a maximum
braking force distribution and thus helps keep
the braking distance to a minimum during full
braking. This system exploits all of the benefits
provided by ABS.
As long as you want full braking to continue, do
not reduce pressure on the brake.
DSC Dynamic Stability Control
DSC prevents slip at the drive wheels when
starting off and accelerating. The system also
detects unstable driving conditions, such as a
fishtailing of the vehicle's rear end or the sliding
of the vehicle on its front wheels. In these cir-
cumstances, DSC helps keep the vehicle on a
safe path, within physical limits, by reducing
engine output and by applying the brakes in
individual wheels.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not squander the additional margin of
safety by driving dangerously; otherwise, you
run the risk of causing an accident.<
Deactivating DSC
Maintain pressure on the button until the DSC
indicator lamp lights up, but do not press for
longer than approx. 10 seconds. DTC Dynamic
Traction Control and DSC are deactivated

jointly. These systems do not take their cus-
tomary stabilizing actions.
To increase vehicle stability, reactivate DSC as
soon as possible.
Activating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out.
For monitoring purposes
When the indicator lamp flashes:
DSC is controlling the drive and braking
forces.
When the indicator lamp lights up:
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a variation of DSC that is optimized for
forward momentum for particular road condi-
tions, e.g. unplowed snow-covered roads. In
this mode, the system assures maximum for-
ward momentum, but with limited driving stabil-
ity. For this reason, drive with corresponding
caution.
In the following exceptional circumstances, it
may be useful to temporarily activate DTC:
>When driving on snow-covered inclines, in
slush, or on unplowed, snow-covered roads
>When freeing a stuck vehicle or starting up
in deep snow, sand, or on a loose ground
surface
>When driving with snow chains
*
Activating DTC
Press the button; the DTC indicator lamp in the
instrument cluster lights up.
For monitoring purposes
When the indicator lamp flashes:
DTC is controlling the drive forces and
braking forces.
When the indicator lamp lights up:
DTC is activated.
Deactivating DTC
Press the button again; the DTC indicator lamp
in the instrument cluster goes out.
xDrive
xDrive is the all-wheel drive system of your X3.
The combined effects of xDrive and DSC fur-
ther optimize the traction and dynamic driving
characteristics. The all-wheel drive system
xDrive variably distributes the drive torque to
the front and rear axle depending on the driving
situation and prevailing road conditions.
HDC Hill Descent Control
The concept
HDC is a system for hill descent assistance that
reduces the speed on steep downward inclines
and makes it even easier to control the driving
characteristics of your BMW under these condi-
tions. The vehicle moves at slightly more than
walking speed without active intervention from
the driver.
You can activate HDC at vehicle speeds below
approx. 20 mph/35 km/h. If it is traveling down a
steep slope at a speed below approx. 20 mph/
35 km/h, the vehicle then automatically decel-
erates down to slightly more than walking
speed, approx. 5 mph/8 km/h, and then keeps
this speed constant.
You can use the accelerator or brakes to vary
this automatically controlled speed within a
range extending from approx. 3 mph/5 km/h to
15 mph/25 km/h.
You can specify a target speed within the same
range by using the +/– buttons of the cruise
control on the steering wheel.

Activating HDC
Press the button; the LED lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating HDC
Press the button again; the LED goes out.
HDC is deactivated immediately above approx.
35 mph/60 km/h and after approx. 10 seconds
when the ignition is switched off.
Using HDC
Manual transmission:
Use HDC in low gears and in reverse.
Automatic transmission:
You can use HDC in every drive position.
Malfunction
If the LED in the button goes out in the HDC
mode or fails to light up when the button is
pressed:
HDC is temporarily not available, because the
brake temperature is too high.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
The brake assistant is malfunctioning.
Have the system checked as soon as
possible.
Display of the previously described mal-
function on Canadian models.
If one of the malfunctions described
below occurs, drive with restraint and
caution and avoid full braking; otherwise, acci-dents can occur. When driving on poor road
surfaces, avoid full throttle or kickdown position
of the accelerator pedal as these could cause
damage to the drive system.<
The warning lamp for the brake system
lights up in red, together with the warn-
ing lamps for ABS and DSC/xDrive. In
addition, a warning signal sounds.
The driving stability control systems
have failed. It is then possible to exert
driving force only via the rear axle.
If the brake system warning lamp lights
up in yellow in the described combination, then
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described mal-
function on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
Both DSC and DTC or the xDrive all-
wheel drive system have failed.
The stabilizing interventions of DSC or the all-
wheel drive system xDrive are no longer avail-
able. It is then possible to exert driving force
only via the rear axle. Have the system checked
as soon as possible.
Acceleration assistant
The acceleration assistant allows you to conve-
niently start off on inclines. You do not have to
use the handbrake.
1.Hold the vehicle with the brake pedal.
2.Step off the brake and immediately start off
with no trouble.
The acceleration assistant holds the vehi-
cle for approx. 2 seconds after the brake
is released. Depending on the load or when
towing a trailer, it is also possible for the vehicle
to roll backward slightly during this interval.

After releasing the brake, start driving immedi-
ately; otherwise, the acceleration assistant will
no longer hold the vehicle after approx. 2 sec-
onds and the vehicle will start to roll back-
ward.<
Malfunction
The warning lamp for the brake system
lights up in yellow. The acceleration
assistant has failed. The vehicle will not
be held after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system triggers an alert whenever
the inflation pressure in one tire drops signifi-
cantly in relation to the pressure in another tire.
When a loss of pressure occurs, the rolling
radius changes and with it, the rotational speed
of the wheels. This change is detected and sig-
naled as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot predict sud-
den severe tire damage caused by out-
side factors and does not detect a natural, even
pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized
>When driving on snow-covered or slippery
road surfaces>Sporty driving style: slip in the drive wheels,
high lateral acceleration.
>When driving with snow chains
*
When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
The initialization is completed while driv-
ing and can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Do not initialize the system when driving with
snow chains
* or with a compact wheel.<
1.Start the engine just before driving, but do
not begin to drive.
2.Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.
3.Begin driving.
The initialization is completed while driving,
without requiring any further input from you.
Indication of a flat tire
The warning lamp lights up red. In addi-
tion, an acoustic signal sounds. There is
a flat tire or extensive inflation pressure
loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<

Wheel changes on page108.
Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.<
The system does not function properly if it has
not been reset, e.g. it may identify a tire as flat in
spite of the fact that the tire is filled to the cor-
rect inflation pressure.
The system is deactivated and is unable to
detect flat tires if a wheel not equipped with
TPM electronics has been mounted, e.g. a
compact wheel, or if TPM is experiencing tem-
porary interference from other systems or
devices that use the same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
1.Start engine, but do not begin to drive.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Wheel changes on page108.
4.Check tire inflation pressure and correct as
needed.

required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.
Have the damaged tire replaced by your BMW
Sports Activity Vehicle Center or a workshop
that is familiar with TPM and works in accor-
dance with BMW repair procedures, using
appropriately trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. Flat tires
cannot be detected.
Such a message is displayed in the following
situations:
>When a malfunction is occurring:
Have the system checked
>When a wheel without TPM electronics is
mounted, e.g. a compact wheel
>When TPM is experiencing temporary inter-
ference from other systems or devices that
use the same frequency
NHTSA/FMVSS-required explanation
of 138 Tire Pressure Monitoring
System
Each tire, including the spare, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
then 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
illuminates a low tire pressure warning lamp
when one or more of your tires are significantly
under-inflated. When the low tire pressure
warning lamp lights up, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly underinflated tire causes the tire to over-
heat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and stop-
ping ability. Please note that the TPMS is not a
substitute for proper tire maintenance, and it is
the driver's responsibility to maintain correct
tire pressure, even if underinflation has not
reached the level to trigger illumination of the
TPMS low tire pressure warning lamp.
The TPMS malfunction indicator is combined
with the low tire pressure warning lamp. When
the system detects a malfunction, the warning
lamp will flash for approximately one minute and
then remain continuously illuminated. This
sequence will continue upon subsequent vehi-
cle startups as long as the malfunction exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunc-
tions may occur for a variety of reasons, includ-
ing the installation of replacement or alternate
tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check
the TPMS malfunction warning lamp after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking
The brake lamps and the center brake lamp
light up.
>Heavy braking
The rear fog lamps light up as well.
