For your own safety
Maintenance and repair
Advanced technology, e.g. the use of
modern materials and powerful electron-
ics, requires specially adapted maintenance
and repair methods. You should therefore have
the corresponding work on your vehicle per-
formed only by your BMW Sports Activity
Vehicle Center or at a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If this work is
not carried out properly, there is a danger of
subsequent damage and related safety haz-
ards.<
California Proposition 65 Warning
California law requires us to state the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior fur-
nishings in a vehicle, contain or emit chemicals
known to the State of California to cause cancer
and birth defects and reproductive harm. In
addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds. Wash
your hands after handling.
Used engine oil contains chemicals that have
caused cancer in laboratory animals. Always

3 Starting engine
Starting engine
Do not run the engine in enclosed spaces;
otherwise, inhalation of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Do not leave the vehicle unattended with the engine running, since an unattended vehicle
with a running engine represents a safety haz-
ard.
To prevent the vehicle from rolling, always shift
into neutral or selector lever position P and
engage the handbrake before leaving the vehi-
cle with the engine running.<
Do not discontinue the starting procedure pre-
maturely, but do not prolong it for more than 20
seconds. Release the ignition key immediately
as soon as the engine starts.
When starting the engine, do not press the
accelerator pedal.
Do not allow the motor to warm up while idling.
Begin driving immediately with moderate
engine speed.
Indicator lamps
The warning lamp lights up. Exhaust
values are deteriorating. Have the vehi-
cle checked as soon as possible.
Under certain conditions, the indicator will flash.
This indicates a serious rate of engine misfire.
When this occurs, you should reduce speed
and consult the nearest BMW Sports Activity
Vehicle Center as soon as possible. Severe
engine misfire, even for only a short period of
time, can seriously damage emission control
components, especially the catalytic converter.

Special starting conditions
In the following situations, press the accelerator
pedal halfway down while starting:
>If the engine fails to start on the first
attempt, for instance, if it is very hot or cold.
>When starting the engine at very low tem-
peratures, below approx. +57/–156, at
high altitudes over approx. 3,300 ft/
1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off engine
Do not remove the ignition key when the
vehicle is rolling; otherwise, the steering
wheel lock would engage during steering.
When leaving the vehicle, remove the ignition
key and lock the steering. When parking on
downward inclines, engage the handbrake; oth-
erwise, the vehicle could start to roll.<
Manual transmission
1.Apply the handbrake.
2.Turn the ignition key to position 1 or 0.
3.Shift into first gear or reverse.
Automatic transmission
1.With the vehicle at a stop, move the selector
lever into position P.
2.Turn the ignition key to position 1 or 0.3.Apply the handbrake.
Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up; an acous-
tic signal also sounds when you begin
to drive. The handbrake is still engaged.

Engaging
The lever engages automatically.
Releasing
Pull up slightly on the lever, press the button
and lower the lever.
If exceptional circumstances should
make it necessary to engage the hand-
brake while the vehicle is in motion, do not pull it
too strongly. In doing so, continuously press the
button of the handbrake lever. Otherwise,
strong application of the handbrake can lead to
overbraking of the rear axle and to associated
'fishtailing' of the vehicle rear end.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<

inadvertently moved into positions R and P. To
release the lock, press the button on the front of
the selector lever handle, refer to arrow.
P Park
Select only when the vehicle is stationary. The
transmission locks to prevent the rear wheels
from turning.

Driving
42 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:
System ready for operation using the
buttons on the steering wheel.
Activating system
As of ignition key position 2:
Press button on steering wheel; the indicator
lamp in the instrument cluster comes on. You
are able to use the cruise control.
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, the controlled speed can
be exceeded. 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 button 1.
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 controlled
speed for an extended period, by pressing
the accelerator, for example
>When DSC is activated
Resuming stored speed
Press button:
The vehicle accelerates to and maintains the
last speed stored.

Technology for comfort, convenience and safety
48
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, etc. Low objects
already displayed, e.g. a curb, can come into the
blind spot of the sensors before a continuous
tone sounds. The system may fail to detect
higher obstacles such as ledges.
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 page78.
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure a stable braking behavior.
DBC Dynamic Brake Control
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. DSC 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 circum-
stances, 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 DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not reduce the additional safety mar-
gin again by taking unnecessary risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine starts.
When the indicator lamp flashes:
DSC is controlling the drive and braking forces.
When the indicator lamp stays lit:
DSC has been switched off with the button.

Deactivating DSC
Press the button; the indicator lamp in the
instrument cluster lights up continuously.
DSC is now deactivated.
Stabilizing interventions of the chassis control
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 useful to switch off DSC for a short
period:
>When rocking the vehicle and starting off in
deep snow or on loose road surfaces
>On sandy road surfaces
>On poor surfaces with deep ruts
>If the wheels spin on muddy surfaces
>When driving with snow chains
As a result of the braking interventions,
the brakes may be subjected to additional
loads when the system is switched off. In order
to limit the brake temperature, brief automatic
suppression of the brake activation is possible.
To maintain vehicle stability, always drive with
the system switched on when possible.<
Reactivating DSC
Press the button again; the indicator lamp in the
instrument cluster goes out. DSC is now acti-
vated.
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.
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 vehicle reduces speed
automatically down to slightly more than walk-
ing 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 +/– buttons of the cruise
control on the steering wheel.
