Service Interval Display
Remaining distance until next
service due
The displays shown in the illustration
appear for a few seconds as of ignition key
position 1 or after starting the engine.
Together with the lettering OILSERVICE or
INSPECTION, the next scheduled service
and remaining distance to this service is
shown in miles/kilometers.
The remaining distance is determined on
the basis of the past driving style.
A flashing display and a Ð before the
numerical value mean that the service
interval has been passed by the displayed
number of miles/kilometers. Please make
an appointment with your BMW Sports
Activity Vehicle Center.
Replacing brake fluid
You can have the month and year for the
scheduled brake fluid replacement dis-
played by pressing the right button in the
instrument cluster while the next sched-
uled service is being displayed. With each
button touch, the display switches
between the scheduled service and
scheduled brake fluid replacement.
When the brake fluid replacement is due,
the clock symbol also lights up. Please
make an appointment with your BMW
Sports Activity Vehicle Center.
Immobilization periods in which the
battery is disconnected are not taken
into account by the display. Please remem-
ber that brake fluid should be changed
every two years at the latest, even if the
display does not yet indicate that service is
required, refer to page 96.<
Clock
If you want to have a permanent clock dis-
play, you can also have the time displayed
in the display of the car radio, refer to the
Owner's Manual for Radio.
You can adjust the clock, also for display in
the radio, as follows.

Limits of the system
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 ultrasonic measurement,
such as those encountered with tow bars
and trailer couplings, or thin and wedge-
shaped objects etc. Low objects already
displayed, e.g. a curb, can also disappear
from the detection area of the sensors
again before a continuous tone sounds.
Loud sources of sound, inside and outside
the vehicle, could drown out the PDC sig-
nal tone.<
Keep the sensors clean and free of ice
or snow in order to ensure that they
will continue to operate effectively.
Do not apply high pressure spray to the
sensors for a prolonged period of time.
Keep the spray at least 4 in/10 cm away
from the sensors.<
Driving stability control
systems
Your BMW is equipped with an extended
array of systems designed to enhance and
maintain vehicle stability under extreme
conditions. The following section describes
these functions based on ABS, DSC, HDC
and xDrive.
Antilock Brake System ABS
ABS enhances active safety by preventing
the wheels from locking under braking. The
vehicle continues to be steerable during
hard braking.
ABS also includes Electronic brake-force
distribution EBV.
Safe braking, refer to page 77.
Electronic brake-force distribution
EBV
EBV controls the brake system's applica-
tion pressure at the rear wheels to ensure
stable deceleration.
Dynamic Brake Control DBC
The Dynamic Brake Control actively sup-
ports the driver in dangerous braking situa-
tions. Quickly pumping the brake pedal
increases the braking effect with low pedal
pressure so that the shortest possible
braking distance is achieved. This system
exploits all of the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. DBC is deactivated when you release
the brake pedal.
Dynamic Stability Control DSC
The concept
DSC maintains vehicle stability, even in
critical driving situations.
The DSC is operational every time you start
the engine.
The system optimizes the driving stability
during acceleration and when starting from
a standstill. The system recognizes any
tendency for the vehicle to assume an
unstable attitude such as oversteer or
understeer; it then counteracts this ten-
dency with a combination of graduated
reductions in engine torque and selective
braking intervention at individual wheels.
DSC provides optimal stability within the
limits defined by the laws of physics.
The laws of physics cannot be
repealed, even with DSC. An appro-
priate driving style always remains the
responsibility of the driver. Avoid using the
additional safety margin provided by the
system as an excuse for taking unneces-
sary risks.
Do not make any modifications to the DSC
system. Never allow anyone other than
authorized professional technicians to
carry out service or repairs on the system.<

Indicator lamp
The indicator lamp in the instrument
cluster goes out soon after you start
the engine.
If the indicator lamp flashes:
DSC is active and is regulating the drive
and braking forces.
The indicator lamp stays lit:
DSC has been switched off using the but-
ton and the stabilizing interventions are no
longer available.
Switching off DSC
Press the button; the indicator lamp comes
on and stays on.
Stabilizing interventions of the chassis con-
trol system DSC are no longer available.
However, the braking interventions that
simulate the function of the differential lock
continue to be active.
In the following exceptional circumstances,
it may be effective to switch off the DSC for
a short period:
>When rocking the vehicle and starting
off in deep snow or on loose road sur-
faces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels churn on muddy surfaces
>When driving with snow chains.
As a result of the braking interven-
tions, the brakes may be subjected to
additional loads when the system is
switched off. In order to limit the brake tem-
perature, brief automatic masking of the
brake activation is possible.
To maintain vehicle stability, always drive with the system switched on when possi-
ble.<
Switching DSC on
Press the DSC button again; the indicator
lamp in the instrument cluster goes out.
DSC is now activated.
xDrive
xDrive is the all-wheel drive system of your
BMW X3. The combined effects of xDrive
and DSC further optimize the traction and
dynamic driving characteristics. The all-
wheel drive system xDrive variably distrib-
utes the drive torque to the front and rear
axle depending on the driving situation and
prevailing road conditions.
Hill Descent Control HDC
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 conditions.
The vehicle moves at slightly more than
walking speed without active intervention
from the driver.
HDC is available for activation at vehicle
speeds below approx. 20 mph/35 km/h.
When driving down steep hills with a speed
below approx. 20 mph/35 km/h, the vehi-
cle reduces speed automatically down to
slightly more than walking speed, approx.
5 mph/8 km/h, and then maintains this
speed at a 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 +/Ð buttons of the
cruise control in the steering wheel.
HDC is automatically deactivated once
vehicle speed again exceeds approx.
35 mph/60 km/h.

Activating the system
Press the button; the indicator lamp comes
on.
The indicator lamp flashes when the brakes
are applied automatically.
Deactivating the system
Press the button again; the indicator lamp
goes out.
Above approx. 35 mph/60 km/h HDC is
immediately deactivated, and when the
ignition is switched off after approx.
10 seconds.
Using HDC
On manual transmission vehicles:
Use HDC in first gear and in reverse gear,
as in the higher gears the engine braking
effect diminishes.
On automatic transmission vehicles:
You can use HDC in every drive position.
Malfunction
If the indicator lamp in the button goes out
in the HDC mode or fails to light up when
the button is pressed:
HDC is temporarily not available, as the
brake temperature is too high.
Malfunctions of the driving stability
control systems
The red brake warning lamp lights
up together with the warning lamps
for ABS and DSC/xDrive. In addi-
tion, a warning signal sounds:
ABS, DSC and xDrive have failed.
Drive may then only be carried out
via the rear axle. Please have it checked by the nearest BMW Sports Activ-
ity Vehicle Center.
Proceed cautiously and defensively.
When driving on poor roads, refrain
from using full throttle and avoid pressing
the accelerator beyond the kickdown point.
Otherwise the drive train may be damaged
or accidents can occur.<
If the brake warning lamp lights up yellow in
the described combination, the Electronic
brake-force distribution EBV is still avail-
able.

available. Drive may then only be carried
out via the rear axle. Please have it
checked by the nearest BMW Sports Activ-
ity Vehicle Center.
Proceed cautiously and defensively.
When driving on poor roads, refrain
from using full throttle and avoid pressing
the accelerator beyond the kickdown point.

Vehicle Center to have the system
repaired.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure another
tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 87 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a
natural, even pressure drop in all four
tires.<
In the following situations, on the other
hand, there can be delays in detecting tire
pressure losses, and even system failure:
>When driving on snow-covered or slip-
pery road surfaces
>In the case of performance-oriented
driving: slip on the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are driv-
ing with snow chains fitted>When driving with a compact wheel, the
Flat Tire Monitor cannot operate.
Initializing the system
Perform the initialization immediately
every time you correct the inflation
pressure, change a tire or change a wheel
or all wheels. A drive is required for this
purpose.<
1.Before the start of driving, start the
engine, but do not drive off
2.Press the button until the yellow indica-
tor lamp in the instrument cluster lights
up for a few seconds
3.Drive off.
It takes a few minutes until the Flat Tire
Monitor can detect and indicated a flat tire.
Do not initialize the system when driv-
ing with snow chains or with a com-
pact wheel.<
Flat tire
Indicator lamp
The symbol in the instrument clus-
ter lights up in yellow.
1.Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2.Identify damaged tire
If identification is not possible,
contact your BMW Sports Activity
Vehicle Center.<
3.Replace the damaged tire, refer to
Changing a wheel on page 103.

Air supply/blower
You can select blower speeds 1
to 4. The heating and ventilation
become more and more effec-
tive as the air supply settings
are increased. In position 0, the
blower and heater are switched off. The air
supply is blocked in position 0.
Temperature
To increase the temperature of
the interior, turn to the right.
Air distribution
You can direct air to flow onto
the windows , toward the
upper body and into the
footwell . All intermediate
settings are possible. In the
setting, there is a low flow of air onto the
windows to keep them free of condensa-
tion.
Rear window defroster
When the rear window
defroster is activated,
the indicator lamp comes on.
The rear window defroster switches off
automatically.
You can have your vehicle pro-
grammed in such a way that the rear
window defroster switches on automati-
cally. It is then switched on at outside tem-
peratures of less than approx. +46/397
within 5 minutes of the engine start.<
Air conditioning
The air is cooled and dehumidi-
fied and Ñ depending on the
temperature setting Ñ warmed
again. Depending on the weather, the
windshield may fog over briefly when the
engine is started. You can reduce conden-
sation forming on the windows by switch-
ing on the air conditioning.
During air conditioning condensation
forms, which then exits under the vehicle. Traces of condensed water of this
kind are thus normal.<
Outside air/recirculated-air mode
You can respond to unpleasant
odors outside the vehicle by
temporarily switching off the
outside air supply. The system then recir-
culates the air currently within the vehicle.
If condensation starts to form on the
inside window surfaces during opera-
tion in the recirculated-air mode, you
should switch it off while also increasing air
supply as required. The recirculated-air
mode should not be used over a sustained
longer period of time, as the air quality
inside the vehicle deteriorates.<
Ventilation
The air vents for the upper body area can
be adjusted:
1Serrated dials 1 for steplessly opening
and closing the air vents
2Selector levers for airflow direction
3Use the serrated dial 3 to adjust the
amount of cool air that is added to the
airflow emerging from the vent outlets
for the upper body
Ventilation for cooling
Adjust the vents to direct the flow of cool
air in your direction, for instance, if the inte-
rior has become too warm, etc.
Draft-free ventilation
Set the vent outlets so that the air flows
past you and is not directed straight at you.
