2010 BMW X3 XDRIVE 30I steering wheel

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.
DTC Dynamic Traction Control
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
BMW. The combined effects of xDrive and DSC
further optimize the traction and dynamic driv-
ing 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.

Technology for comfort, convenience and safety
54 After releasing the brake, start driving immedi-
ately; otherwise, the acceleration assistant will
no longer hold the vehicle after approx.
2 seconds and the vehicle will start to roll back-
ward.<
Malfunction
The warning lamp for the brake system
lights up in yellow. The acceleration
assistant has failed. The vehicle will not
be held after the brake is released. Have the
system checked as soon as possible.
Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects a pressure loss in
a tire based on comparing the speeds of the
individual wheels while driving.
In the event of a pressure loss, a change occurs
in the rolling circumference and therefore the
rotation speed of the corresponding wheel.
This change is detected and signaled as a flat
tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be carried out after
each correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot predict sud-
den severe tire damage caused by out-
side factors and does not detect a natural, even
pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>When the system has not been initialized
>When driving on snow-covered or slippery
road surfaces
>Sporty driving style: slip in the drive wheels,
high lateral acceleration.>When driving with snow chains
*
When driving with a compact wheel, the Flat
Tire Monitor cannot operate.
Initializing system
The initialization is completed while driv-
ing and can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Do not initialize the system when driving with
snow chains
* or with a compact wheel.<
1.Start the engine just before driving, but do
not begin to drive.
2.Press the button for at least 4 seconds, but
not longer than 2 minutes. After the button
is released, the indicator lamp in the instru-
ment cluster lights up yellow for a few sec-
onds.
3.Begin driving.
The initialization is completed while driving,
without requiring any further input from you.
Indication of a flat tire
The warning lamp lights up red. In addi-
tion, an acoustic signal sounds. 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
Wheel changes on page115.

Malfunction
The warning lamp lights up yellow. The
Flat Tire Monitor is malfunctioning or
out of order. Have the system checked
as soon as possible.
TPM Tire Pressure Monitor*
The concept
TPM controls the tire inflation pressure in the
four mounted wheels. The system notifies you
if the tire inflation pressure has fallen signifi-
cantly in one or more tires.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be reset at the correct tire inflation
pressure.
Always use wheels equipped with TPM elec-
tronics, including a metal valve; otherwise, there
is no guarantee that the system will function
properly.
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot warn you of sudden, serious
tire damage due to external factors.<
The system does not function properly if it has
not been reset, e.g. it may identify a tire as flat in
spite of the fact that the tire is filled to the cor-
rect inflation pressure.
The system is deactivated and is unable to
detect flat tires if a wheel not equipped with
TPM electronics has been mounted, e.g. a
compact wheel, or if TPM is experiencing tem-
porary interference from other systems or
devices that use the same frequency.
Resetting system
The system must be reset after every cor-
rection of tire inflation pressure and after
every tire or wheel change.<1.Start engine, but do not begin to drive.
2.Press the button until the yellow warning
lamp in the instrument cluster lights up for a
few seconds.
3.Begin driving.
After a few minutes of driving, the tire infla-
tion pressures in the tires are adopted as
the desired values to be monitored. The
resetting is completed during driving and
can be interrupted at any time without
requiring any input from you. The resetting
automatically continues when driving
resumes.
Low tire pressure message
The warning lamp lights up yellow. In
addition, a signal sounds. You have a
flat tire or a significant loss of tire pres-
sure in one or more tires.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify the damaged wheel or wheels.
If identification is not possible, con-
tact your BMW Sports Activity Vehi-
cle Center.<
3.Replace the damaged wheel, refer to
Wheel changes on page115.
4.Check tire inflation pressure and correct as
needed.
The compact wheel is not equipped with the
required TPM electronics and is not monitored
when mounted.
When driving with the compact wheel, the sys-
tem indicates a malfunction.

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 optimum protection,
please follow the instructions on page27.<
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 cushions the side upper body area. The
respective head airbag cushions the head.
The airbags are intentionally not triggered in
every collision situation, e.g. they are not trig-
gered not in less serious accidents, 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.
Keep the instrument cluster and the windshield
in the region of the passenger free of foreign
objects, i.e. do not cover them with adhesive foil
or coatings, and do not use these areas to
mount brackets, e.g. for a navigation device or
mobile phone.
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 instrument
cluster, 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.
In the event of malfunctions, deactivation, or
triggering of the airbag restraint system, have
the testing, repair, removal, and disposal of air-
bag generators executed only by a BMW Sports
Activity Vehicle Center or a workshop that
works according to BMW repair procedures
with correspondingly trained personnel and
that has the required explosives licenses. Oth-
erwise, unprofessional attempts to service the
system could lead to failure in an emergency or
undesired airbag activation, either of which
could result in personal injury.<
Airbag warnings and information are also pro-
vided on the sun visors.
Automatic deactivation of front
passenger airbags
By evaluating the pressure on the seat cushion
of the front passenger seat, the system detects
whether or not the seat is occupied. Depending
on the detection result, the system correspond-
ingly activates or deactivates the front and side
airbags for the passenger.
The indicator lamp located above the
inside rearview mirror indicates whether
the front passenger airbag system is currently
deactivated or activated, refer to Status of pas-
senger airbags in the section below.<
Before transporting a child in the front
passenger seat, read the safety notices
and follow the safety instructions under Trans-
porting children safely on page35.
When teenagers or adults assume certain sit-
ting positions, the front and side airbags on the
passenger side can deactivate; this causes the
indicator lamp for the front passenger airbag to
light up. If this happens, have them change their
sitting position so that the passenger airbag is
activated and the indicator lamp goes out. If the
desired status cannot be achieved by changing
their sitting position, then have the person ride

Roof-mounted luggage rack*
A special rack system is available as an optional
accessory for your BMW. Please familiarize
yourself with the information contained in the
installation instructions.
Loading luggage rack
Because roof racks raise the vehicle's center of
gravity when loaded, they have a major effect on
its handling and steering response. You should
therefore always remember not to exceed the
approved roof load capacity, the approved
gross vehicle weight, or the axle weights when
loading the rack.
These specifications can be found under
Weights on page128.
The roof load must be evenly distributed and
must not extend outward beyond the limits of
the loading surface. Always stow the heaviest
pieces on the bottom. Be sure that adequate
clearance is maintained for raising the glass
sunroof and that objects do not project into the
opening path of the liftgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or falling off
while you drive.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
Driving on poor roads
Y our B MW is a t home on all pa ve d a nd unpa ved
roads. It combines all-wheel drive with the
advantages of a normal passenger car.
Do not drive off-road, as otherwise the
vehicle may be damaged.<
When you are driving on poor roads, there are a
few points which you should strictly observe –
for your own safety and that of your passengers,
as well as to protect the vehicle:
>Familiarize yourself with the vehicle before
you begin driving. Do not take risks with the
vehicle under any circumstances.>Always adapt your driving speed to the road
conditions. The more steep and uneven the
roadway is, the lower the speed should be.
>You can operate your vehicle on uphill and
downhill gradients with a maximum slope
of 50 %. If you wish to drive on uphill and
downhill grades of this nature, make sure
beforehand that the engine oil and coolant
levels are near the MAX mark, refer to
pages103 and105.
>When descending very steep hills, use
HDC Hill Descent Control, refer to page52.
It is possible to start off on inclines of up
to 32 %.
The permitted side tilt is 32 %.
>While driving, watch carefully for obstacles
such as rocks or holes. Try to avoid these
obstacles whenever possible.
>Avoid having the body make contact with
the ground, e.g. on the crests of hills and
bumpy roads. The ground clearance of the
vehicle is a maximum of approx. 8.0 in/
20 cm. Please be aware that the ground
clearance can vary depending on the load
and operating conditions of the 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.
To clean 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.
>Depending on the road condition, it can be
useful to temporarily activate DTC, refer to
DTC Dynamic Traction Control on page52.
>If the drive wheels spin on one side, depress
the accelerator pedal far enough to permit
the driving stability control systems to dis-

with appropriately trained personnel.
Wheel changes
Safety precautions to observe in the
event of a flat tire and during all tire
changes:
Park the vehicle as far as possible from passing
traffic. Park on a firm, flat, surface. Switch on the
hazard warning flashers.
Lock the steering wheel with the wheels point-
ing straight ahead. Engage the handbrake and
shift into first gear or reverse, or move the
selector lever to position P.
All passengers should be outside the vehicle
and well away from your immediate working
area, behind a guardrail, for instance.
If a warning triangle
* or portable hazard warning
lamp
* is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tile, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<

Replacing components
118 Protect valve stems with valve stem
seal caps from dirt and contamina-
tion. Dirt in valve stems is a frequent source
of gradual air loss.<
4.Reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to
pages54, 55.
Do not initialize the Flat Tire Monitor
when driving with a compact wheel.<
5.Replace the defective tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
Mounting the compact wheel can change the
driving characteristics. For example, it can
reduce tracking stability during braking, extend
braking distances, and alter self-steering char-
acteristics in the limit range. With winter tires,
these characteristics are more pronounced.
Only one compact wheel may be
mounted. You should re-equip with
wheels and tires of the original size as soon as
possible.<
Vehicle battery
Maintenance
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be happy to advise you on all questions con-
cerning the battery.
Warning lamp
The warning lamp lights up. The battery
is no longer being charged. The alterna-
tor V-belt is defective or there is a mal-
function in the charge current circuit of the
alternator. Have the system checked immedi-
ately.Do not continue driving if the V-belt is
defective. The engine could be damaged
due to overheating.
Moreover, an increased amount of force is
required for steering if there is a sharp drop in
the onboard supply voltage.<
Charging battery
Charge the battery in the vehicle only when the
engine has been switched off. For connections,
refer to Jump starting on page121.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always secure the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power supply interruption,
some equipment is subject to limited use and
must be reinitialized. Individual settings are also
lost and must be updated again:
>Panorama glass sunroof
It may be only possible to raise the sunroof.
The system must be initialized, refer to
page24.
>Power windows
The pinch protection system must be reini-
tialized, refer to page23.
>Seat and mirror memory
The positions must be stored again, refer to
page31.
>Time
Must be set again, refer to page47.
