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.

Automatic transmission
1.Step on the brake.
2.Move selector lever into position P.
3.Start the engine.
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.
Indicator lamp for Canadian models.
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.<

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.

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.

Activating system
Press the button; the LED lights up.
The LED flashes when the brakes are applied
automatically.
Deactivating system
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
With manual transmission:
Use HDC in first gear and in reverse, because in
the higher gears the engine's braking action
diminishes.
With 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

Dynamic Brake Control is malfunction-
ing. 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, proceed cautiously and
defensively. When driving on poor roads, avoid
using the full throttle or kick-down positions of
the accelerator as well as heavy and panic brak-
ing. Otherwise, the drive train may be damaged
or accidents can occur.<
The red brake warning lamp lights up
together with the warning lamps for
ABS and DSC/xDrive. In addition, a
warning signal sounds. ABS, DSC, HDC
and xDrive have failed. It is then possi-
ble to exert driving force only via the
rear axle. If the brake warning lamp
lights up yellow in the described combi-
nation, the EBV Electronic brake-force distribu-
tion is still available. 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

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:
>In the event of a malfunction:
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
Brake force display
The brake lamps light up in two stages,
depending on how heavily you apply the brakes.
>Normal braking:
The brake lamps 1 and the center brake
lamp light up.
>Powerful braking:
The brake lamps 1 and 2 light up together
with the center brake lamp.
Airbags
The following airbags are located beneath the
marked covers:
1Front airbags
2Head airbags
3Side airbags in front and rear
*
Protective action
To ensure that the safety systems con-
tinue to provide optimal protection,
please follow the instructions on page26.<
The front airbags help protect the driver and
front passenger by responding to frontal
impacts in which safety belts alone cannot pro-
vide adequate restraint. When needed, the
head and side airbags help provide protection in
the event of side impact. The relevant side air-
bag supports the side upper body area. The
respective head airbag supports the head.
The airbags will purposely not be activated by
every collision, e.g. not by more minor acci-
dents, or rear-end collisions.
Do not apply adhesive materials to the
cover panels of the airbags, cover them or
modify them in any other way.
Do not attempt to remove the airbag retention
system from the vehicle. Do not modify the indi-
vidual components of the system or its wiring in
any way. This includes the padded covers in the
center of the steering wheel, on the dashboard,
the doors, and the roof pillars as well as the
sides of the headliner. Do not attempt to
remove or dismantle the steering wheel.
Do not touch the individual components
directly after the system has been triggered,
because there is a danger of burns.

Things to remember when driving
Breaking-in
Moving parts should be allowed to adjust to one
another. To ensure that your vehicle provides
maximum economy throughout a long service
life, we request that you observe the following
instructions.
Engine and differential
Always obey all official speed limits.
For the first 1,200 miles/2,000 km
Drive at varying engine and driving speeds, but
do not exceed 4,500 rpm or 100 mph / 160 km/h
in the process.
Refrain from using full throttle and avoid press-
ing the accelerator beyond the kick-down point.
After 1,200 miles/2000 km
Engine and road speed can be gradually
increased.
Tires
Due to technical factors associated with their
manufacture, tires do not achieve their full trac-
tion potential until after an initial break-in
period. For this reason, drive with extra care
during the initial 200 miles/300 km.
Obey your local and state maximum speed lim-
its.
When the vehicle is operated on wet or
slushy roads, a wedge of water may form
between the tire and the road surface. This phe-
nomenon is referred to as hydroplaning and can
lead to partial or complete loss of traction, vehi-
cle control and braking effectiveness. Reduce
your speed on wet roads.<
Brake system
Your vehicle must travel approx. 300 miles/
500 km before the brake pads and rotors
achieve the optimal pad-surface and wear patterns required for trouble-free operation and
long service life later on.
To break in the separate handbrake drums,
apply the handbrake lightly when coasting to a
stop – at a traffic signal, for instance; use cau-
tion to avoid posing a danger to other road
users.
To avoid corrosion, repeat this procedure from
time to time.
The brake lamps do not come on when the
handbrake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the vehicle
with the engine off – e.g., by towing – substan-
tially higher levels of pedal force will be required
to brake the vehicle.<
Clutch
The function of the clutch reaches its optimal
level only after a distance driven of approx.
300 miles/500 km. During this break-in period,
engage the clutch gently.
Following component replacements
Follow the break-in sequence again if compo-
nents addressed above must be replaced due
to subsequent driving.
General driving notes
Close the liftgate
Operate the vehicle only when the liftgate
is completely closed; otherwise, exhaust
fumes could enter the interior of the vehicle.<
If special circumstances should make it abso-
lutely necessary to operate the vehicle with the
liftgate open:

Things to remember when driving
78
Safe braking
Your BMW is equipped with ABS as standard
equipment. In situations in which it is required, it
is best to apply the brakes fully. Since the vehi-
cle maintains steering responsiveness, you can
nevertheless avoid possible obstacles with a
minimum of steering effort.
Pulsation at the brake pedal combined with
sounds from the hydraulic circuits indicates to
the driver that ABS is in its active mode.
Wet roads
On wet roads or in heavy rain, briefly apply light
pressure to the brake pedal every few miles.
Watch traffic conditions to ensure that this
maneuver does not endanger other road users.
The heat that is generated by the brake applica-
tions helps to dry the brake pads and rotors.
The full braking force will then be available
when you need it.
Hills
To prevent overheating and reduced effi-
ciency of the brake system, drive long or
steep downhill grades in the gear in which the
least braking is required. Otherwise, even light
but continuous pressure on the brake can lead
to high temperatures, brake wear and possibly
even brake failure.<
The braking action of the engine can be further
intensified by downshifting, all the way down to
first gear if need be. This strategy helps you
avoid placing excessive loads on the brake sys-
tem. Downshifting in manual mode of automatic
transmission, refer to page39. When descend-
ing hills slowly, use HDC Hill Descent Control,
refer to page49.
Never drive with the clutch depressed,
with the transmission in neutral, or with
the engine switched off; otherwise, you will
have neither the braking action of the engine or
nor its power assistance to the brakes or steer-
ing.
Never allow floor mats, carpeting, or other arti-
cles to protrude into the area around the brake
or accelerator pedals and obstruct their move-
ment.<
Corrosion on brake rotors
When the vehicle is driven only occasionally,
during extended periods when the vehicle is not
used at all, and in operating conditions where
brake applications are less frequent, there is an
increased tendency for corrosion to form on
rotors, while contaminants accumulate on the
brake pads. This occurs because the minimal
pressure which must be exerted by the pads
during brake applications to clean the rotors is
not reached.
Should corrosion form on the brake rotors, the
brakes will tend to respond with a pulsating
effect that even extended application will fail to
cure.
Cargo loading
To avoid loading the tires beyond their
approved carrying capacity, never over-
load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
develops inside the tires. The ultimate result
can assume the form of a sudden blow-out.<
Determining load limit
1.Locate the following statement on your
vehicle's placard
*:
The combined weight of occupants
and cargo should never exceed
XXX lbs. or YYY kg. Otherwise, the vehicle
may be damaged and unstable driving con-
ditions may result.<
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.

>Do not drive in water that is deeper than
20 in/50 cm. If you must drive through water
up to that depth, drive at a walking speed
and do not stop.
After leaving the water, press on the foot-
brake gently several times while driving at a
low speed. The brake applications will help
to dry the brakes, thus preventing a reduc-
tion in braking performance caused by the
moisture.
For cleaning the handbrake, apply the lever
slightly at approx. 25 mph/40 km/h and con-
tinue to drive for approx. 200 yards/
200 meters, provided that traffic conditions
allow you to do so.
Please bear the following points in mind after
driving on poor roads, in order to preserve the
road safety of your BMW:
>Clean the heavy dirt from the body.
>Clean mud, snow, ice and other materials
from the wheels and tires. Check the tires
for damage.
