Display of the previously described
malfunction on Canadian models.
The warning lamp lights up. Malfunc-
tion in the engine electronics. You can
continue to drive with reduced engine
output or speed. Have the system checked
immediately.
Starting engine
When starting the engine, do not press the
accelerator pedal.
Vehicles with manual transmission:
Step on the clutch when starting the vehicle.
A locking mechanism prevents the engine from
starting if the clutch is not depressed.
Do not end the starting procedure too early, but
do not prolong it for more than 20 seconds.
Release the ignition key immediately as soon as
the engine starts.
If the engine fails to start on the first attempt, for
instance, if it is very hot or cold:
Press the accelerator pedal halfway down while
engaging the starter.
During a cold start at very low temperatures,
below approx. +57/–156, at high altitudes
over 3,300 ft/1,000 m:
>Engage the starter for approx. 10 seconds
the first time.
>Press the accelerator pedal halfway down
while engaging the starter.
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.<
Manual transmission
1.Apply the handbrake.
2.Shift into neutral.
3.Press the clutch pedal.
If the clutch pedal is not pressed, the engine
cannot be started.
4.Start the engine.Before leaving the vehicle with the engine
running, place the gearshift lever in neu-
tral position and engage the handbrake.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.<
Automatic transmission
1.Press the brake pedal.
2.Engage selector-lever position P or N.
3.Start the engine.
To prevent the vehicle from rolling,
always select position P and engage the
handbrake before leaving the vehicle with the
engine running. Never leave an unattended
vehicle with the engine running, as such a vehi-
cle represents a potential safety hazard.<
Switching off engine
Do not remove the ignition key when the
vehicle is moving, as otherwise the steer-
ing could lock.
When leaving the vehicle, always remove the
ignition key and lock the steering.
When parking on downward inclines, engage
the handbrake.<
Manual transmission
Turn the ignition key to position 1 or 0.
Automatic transmission
Engage selector-lever position P, turn ignition
key to position 1 or 0.
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 red. An
acoustic signal also sounds when you
begin to drive. The handbrake is
engaged.

Driving
36 Indicator lamp for Canadian models.
Engaging
The lever engages automatically and the indica-
tor lamp in the instrument cluster lights up from
ignition key position 1.
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. Strong applica-
tion of the handbrake can lead to overbraking of
the rear axle and to associated 'fishtailing' of the
vehicle rear end.
The brake lamps do not light up when the hand-
brake is applied.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
brake lightly when the vehicle is slowly coming
to a stop at a traffic light if the traffic conditions
are suitable.<
Manual transmission
When shifting into 5th or 6th gear, make
sure that you press the gearshift lever to
the right to prevent inadvertently shifting into
3rd or 4th.
Do not hold the vehicle in place on slopes by
slipping or riding the clutch. Otherwise greater
clutch wear will result.<
Reverse
Select only when the vehicle is stationary. Press
the gearshift lever to the left to overcome the
resistance.
As you do this, the backup lamps will turn on
automatically when the ignition key is in posi-
tion 2.
Automatic transmission with
Steptronic
In addition to fully automatic operation, you can
also manually shift with the Steptronic, refer to
page37.

Switching off 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 indicator lamp comes on.
The indicator lamp flashes when the brakes are
applied automatically.
Deactivating system
Press the button again; the indicator lamp 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
In vehicles with manual transmission:
Use HDC in first gear and in reverse gear, as in
the higher gears the engine's braking action
diminishes.
On vehicles with automatic transmission:
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.
Malfunction in vehicle stability control
systems
The warning lamp lights up yellow.
DBC Dynamic Brake Control is defec-
tive. Have the system checked as soon
as possible.
Display of the previously described
malfunction 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. Drive may
then only be carried out via the rear
axle. If the brake warning lamp lights up
yellow in the described combination,
the EBV Electronic brake-force distribution is
still available. Have the system checked as soon
as possible.
Display of the previously described
malfunction on Canadian models.
The warning lamp lights up continu-
ously and a warning signal sounds:
DSC or the xDrive all-wheel system has
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.
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the four mounted tires as you
drive. The system provides an alert whenever
the inflation pressure drops significantly in rela-
tion to the pressure in another tire.

Technology for comfort, convenience and safety
50 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 certain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the cor-
rect inflation pressure, please perform the fol-
lowing steps:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure table
on page83 and correct if necessary
3.Initialize the system.
System limits
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 slippery
road surfaces.
>In the case of performance-oriented driving:
slip in the drive wheels, high lateral acceler-
ation.
>False alarms and undetected loss of pres-
sure may occur when you are driving with
snow chains fitted.
>When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
Perform the initialization immediately
every time you correct the inflation pres-
sure, change a tire or change a wheel or all
wheels. This requires a trip.<1.Start the engine, but do not begin to drive.
2.Press the button until the yellow indicator
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
It takes a few minutes until the Flat Tire Monitor
can detect and indicate a flat tire.
Do not initialize the system when driving
with snow chains or with a compact
wheel.<
Indication of a flat tire
The warning lamp lights up yellow.
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.<
3.Replace the damaged wheel, refer to
Changing a wheel on page99.
Brake Force Display
The Brake Force Display lights up in two
stages, depending on how heavily you brake.

with the center brake lamp.
Airbags
The following airbags are located beneath the
marked covers:
1Front airbags for driver and front passenger
2Head airbags in front and rear
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 page24.<
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 air bag supports the head.
The airbags are deliberately not triggered in
every impact situation, e.g. less severe acci-
dents, certain roll-over situations or rear-end
collisions.
Labels in the rear door opening should
indicate the status of your rear seat side
airbags. If you are uncertain of their status, or
wish to have the airbags activated or deacti-
vated, please contact your BMW Sports Activity
Vehicle Center.<
For information on the correct sitting position,
refer to page24.
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. Never modify or
tamper with either the wiring or the individual
components in the airbag system. This cate-
gory includes the upholstery in the center of the
steering wheel, on the instrument cluster, the
side trim panels on the doors, and the roof pil-
lars along with 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. When there
are malfunctions, when deactivating, or after
the triggering of the airbag restraint system,
have the testing, repair, removal, and disposal
of the airbag generators executed only by your
BMW Sports Activity Vehicle Center or at a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel and has the required explosives
licenses. Unprofessional attempts to service
the system could lead to failure in an emer-
gency or undesired airbag activation, either of
which could result in personal injury.<
Airbag warning information is also provided on
the sun visors.
