Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
with
+ are checked for proper function each
time you turn the ignition key. They each light
up once for different periods of time.
When a malfunction occurs in a monitored sys-
tem, the corresponding lamp will either fail to go
o u t w h e n t h e e n g i n e i s s t a r t e d , o r i t w i l l c o m e o n
again during normal driving. Detailed informa-
tion is provided on the specified pages.

Cruise control44
With ignition key in position 2, this
warning lamp indicates that a door
or the liftgate is open.

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 page84.
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

Technology for comfort, convenience and safety
52 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.

Wheels and tires
98 age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
Correct wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After tire
damage, always remember to have the original
wheel and tire combination remounted on the
vehicle as soon as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page55. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.
Changing wheels from one axle to
another
BMW does not recommend changing the front
wheels to the back or vice versa as this can
impair handling characteristics.
