recommended for a performance-oriented
driving style.
When the selector lever is moved briefly
towards + or –, manual operation is activated
and the Steptronic shifts gears. The instrument
cluster shows M1 through M5.
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; as a result, for
example, a downshift that would cause the
engine to overrev will not be executed by the
system. The gear selected will appear briefly in
the instrument cluster followed by the current
gear.

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.

Car phone preparation*
Hands-free system
In vehicles with car phone preparation*, the
hands-free microphone is located on the head-
liner near the interior lamp.
For more information on the car phone, refer to
the Owner's Manual for Telephone.
Ski bag*
The ski bag allows the safe and clean transport
of up to 4 pairs of standard skis or up to two
snowboards.
The ski bag itself plus the additional capacity
provided by the cargo area make it possible to
transport skis with a length of up to 6.9 ft/
2.10 m. When skis of 6.9 ft/2.10 m in length are
loaded the ski bag will tend to narrow, reducing
its overall capacity.
Loading
1.Fold down the center armrest, pull off the
cover, press the button and remove the
cover.
2.Press the button again; the cover in the
cargo area opens. If you press the button firmly the first time, this also opens the
cover in the cargo area.
3.Place the ski bag between the front seats
and load.
The zipper facilitates access to the stowed
items.
4.Insert the belt tongue of the ski bag retain-
ing belt into the center safety belt buckle.
Make sure to load only clean skis into the ski
bag. Wrap sharp edges so that no damage
occurs.
Securing load
After loading, secure the ski bag and its con-
tents. Tension the retaining strap on the ten-
sioning buckle for this purpose.
Secure the ski bag in this way. If you fail to
do so, it could endanger occupants dur-
ing braking or evasive maneuvers.<
To store the ski bag, perform the above steps in
reverse order.

3.Subtract the combined weight of the driver
and passengers from XXX lbs. or YYY kg.
4.The resulting figure equals the available
amount of cargo and luggage load capacity.
For example, if the XXX amount equals
990 lbs. and there will be five 150-lbs. pas-
sengers in your vehicle, the amount of avail-
able cargo and luggage load capacity is
240 lbs.:
990 lbs. minus 750 lbs. = 240 lbs.
5.Determine the combined weight of luggage
and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in step 4.
6.If your vehicle will be towing a trailer, part of
the load from your trailer will be transferred
to your vehicle. Consult the manual for
transporting a trailer to determine how this
may reduce the available cargo and luggage
load capacity of your vehicle.
Load
The permitted load is the total of the weight of
occupants and cargo/luggage. The greater the
weight of occupants, the less cargo/luggage
can be transported.
Stowing cargo
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
bulkhead behind the rear seats.
>Cover sharp edges and corners.
>Pull out the partition net, refer to page68,
making sure that objects cannot penetrate
the partition net.
>Do not stack cargo higher than the upper
edge of the backrests.
>Items that could bump against the rear win-
dow while driving must be adequately cov-
ered.
>For very heavy cargo when the rear seat is
not occupied, secure each safety belt in the
opposite buckle.
Securing cargo
>Use the luggage net* to hold down small
and lightweight luggage and cargo, refer to
page68.
>For larger and heavier pieces, heavy-duty
cargo straps
* are available from your BMW
Sports Activity Vehicle Center. Lashing
eyes for attaching these heavy-duty cargo
straps have been provided in your vehicle's
cargo area, refer to page69.

Things to remember when driving
76 >Read and comply with the information
enclosed with the heavy-duty cargo straps.
Always position and secure the load as
described above. If you do not, it can even
endanger the passengers during braking or
evasive maneuvers.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page112, as excessive loads can pose a
safety hazard, and may also place you in viola-
tion of freeway safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could fly around and pose a safety
hazard to the vehicle's occupants during abrupt
braking or evasive maneuvers.<
Roof-mounted luggage rack*
A special rack system is available as a optional
accessory for your BMW. Please observe the
information contained in the installation instruc-
tions.
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 weight, the approved gross vehi-
cle weight or the axle loads when loading the
rack.
You can find the specified weights in the Tech-
nical data section on page112.
Make sure that the load is evenly distributed,
and that it does not extend outward to beyond
the limits of the loading surface. Always load the
heaviest pieces first – on the bottom. Be sure
that adequate clearance is maintained for rais-
ing the glass sunroof, and that objects do not
project into the opening path of the tailgate.
Secure roof-mounted cargo correctly and
securely to prevent it from shifting or being lost
during the trip.
Drive smoothly. Avoid sudden acceleration and
braking maneuvers. Take corners gently.
Driving on poor roads
Your X3 is at home on all paved and unpaved
roads. It combines all-wheel drive with the
advantages of a normal passenger car.
Driving on unpaved terrain can cause
damage to the vehicle.<
When you are driving on poor roads, there are a
few points which you should strictly observe –
for your own safety, for that of your passengers,
and for the safety of the vehicle:
>Familiarize yourself with the vehicle before
you begin driving. Do not take risks with the
vehicle under any circumstances.
>Always adapt the 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
pages90 and91.
>For very steep downhill driving, use HDC
Hill Descent Control, refer to page48. It is
possible to start off on upward 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 that the body makes 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 operat-
ing 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

Under the hood
Never attempt to perform any service or
repair operations on your vehicle without
the required professional technical training. If
you are not familiar with the regulations to be
observed, have work on your vehicle carried out
only by a BMW Sports Activity Vehicle Center
or a workshop that uses personnel trained in
accordance with BMW requirements. If this
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety
hazards.<
Hood
Unlocking
Pull the lever located under the left side of the
instrument cluster.
Opening
Press the release handle and open the hood.
Closing
Let the hood fall from approx. 1 ft/30 cm so that
you hear it engage.
Observe the same precautions that apply
to all closing operations by ensuring that
the hood's travel range is clear and unob-
structed before allowing the hood to fall into
position.
If you see any signs that the hood is not com-
pletely closed while driving your vehicle, you
should stop at once and close it securely.<
