Seats
Note before adjusting
Never try to adjust your seat while operat-
ing the vehicle. The seat could respond
with unexpected movement, and the ensuing
loss of vehicle control could lead to an accident.
On the passenger seat as well, do not incline
the backrest too far to the rear while the vehicle
is being driven; otherwise, there is a danger in
the event of an accident of sliding under the
safety belt, eliminating the protection normally
provided by the belt.<
Also follow the instructions regarding the
height of head restraints on page28 and
regarding safety belt damage on page30.
Adjusting manually

Transporting children safely
The right place for children
Do not leave children unattended in the
vehicle; otherwise, they could endanger
themselves and/or others, for example by open-
ing the doors.<
Children always in the rear
Accident research has demonstrated that the
safest place for children is in the rear seat.
Children younger than 13 or smaller than
5 ft/150 cm should only ride in the rear, in
child restraint systems provided in accordance
with their age, weight, and height. Otherwise,
there is an increased risk of injury in the event of
an accident.<
Children older than 13 must be secured with a
safety belt as soon as they have outgrown a
suitable child restraint system due to their age,
height, and weight.
All seats in your BMW, except for the driver's
seat, correspond to the recommendations of
the norm SAE J1819 for safely securing child
restraint systems in motor vehicles.
Exception for the front passenger seat
If it should be necessary to use a child
restraint system on the front passenger
seat, the front and side airbags must be deacti-
vated. Otherwise, there is an increased risk of
injury to the child if the airbag is triggered, even
with a child restraint system. Your BMW Sports
Activity Vehicle Center will be happy to advise
you.<
For more information on automatic deactivation
of the front passenger airbags, refer to page54.
Installing child restraint
systems
Follow the child restraint system manu-
facturer's instructions for selection,
installation and use of the child restraint sys-
tem. Otherwise, the degree of protection can be
reduced.<
On the passenger's seat
Before installing a child restraint system
in the passenger seat, make sure that the
front and side airbag on the passenger seat
have been deactivated. Otherwise, there is an
increased risk of injury when the airbag is trig-
gered.<
Child seat security
All rear seat safety belts and the safety belt for
the front passenger can be locked to prevent
their being pulled out in order to fasten child
restraint systems.
Locking safety belt
1.Secure child restraint system with the belt.
2.Pull safety belt strap all the way out.
3.Allow safety belt to retract and pull it snugly
against the child restraint system.
The safety belt is locked.
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.

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-lb. 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 into and/or onto the
vehicle. This combined weight may not
safely exceed the available cargo and lug-
gage 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
>To protect passengers, use the partition
net, refer to page72.
>Load heavy cargo as far forward and as low
as possible, placing it directly behind the
rear seat backrests.
>Cover sharp edges and corners.
>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* o r d ra w s t r a p s t o h o l d
down small and lightweight luggage and
cargo, refer to page73.
>For larger and heavier pieces, heavy-duty
cargo straps
* are available from your BMW
Sports Activity Vehicle Center. These
heavy-duty cargo straps are attached using
the lashing eyes in the cargo area, refer to
page73.
Things to remember when driving
80 Please read the information provided with
the heavy-duty cargo straps.
Always position and secure cargo as
described above. If you do not, it can
endanger the passengers during braking or
evasive maneuvers.
Use only the lashing eyes, refer to page73, to
fasten the heavy-duty cargo straps; otherwise,
the heavy-duty cargo straps could loosen or the
vehicle could be damaged.
Never exceed either the approved gross vehicle
weight or either of the approved axle loads, refer
to page116, as excessive loads can pose a
safety hazard and may also place you in viola-
tion of road safety laws.
You should never transport heavy or hard
objects unsecured in the passenger compart-
ment, as they could be thrown about 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 an 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 load capacity, the approved
gross vehicle weight, or the axle loads when
loading the rack.
These specifications can be found under
Weights on page116.
Make sure that the load is evenly distributed,
and that it does not extend outward beyond the
limits of the loading surface. Always stow the
heaviest pieces at the bottom. Be sure that ade-
quate 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
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 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 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
pages94 and95.
>When descending very steep hills, use
HDC Hill Descent Control, refer to page49.
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.

Never attempt to continue driving until
the tank is completely empty; this can
negatively affect engine function and can dam-
age the vehicle.<
Fuel specifications
Never use leaded gasoline. Otherwise,
you will cause permanent damage to your
catalytic converter.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with a
lower AKI rating. The minimum AKI rating is 87.
If you use gasoline with this minimum AKI rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no effect on the engine life.
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2,8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
stalling, starting and drivability problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems that
you suspect could be related to the fuel you are
using, we recommend that you respond by
switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.
Failure to comply with these recommendations
may also result in unscheduled maintenance.<

Replacing components
104 3.Turn the handle to the left as far as possible,
refer to arrow3.
Turning the handle releases the com-
pact wheel. Its weight of approx.
18 lbs./8 kg is then entirely supported by
the handle.<
4.Slowly lower the handle as far as possible,
refer to arrow4.
5.Pull the compact wheel to the rear so that it
is still securely resting in its compact wheel
receptacle.
6.If need be, turn the wheel in the compact
wheel receptacle so that the attachment of
the retaining strap to the rim points toward
the rear.
7.Rotate the clamp by 180°, refer to arrows 1,
and unhook the retaining strap from the
clamp, refer to arrow 2.
8.Take out the compact wheel toward the
back.
9.Fasten the retaining strap to the compact
wheel receptacle and resecure the compact
wheel receptacle by reversing the above
steps.
The width of the defective wheel prevents
it from fitting into the compact wheel receptacle in place of the compact wheel
itself.<
Inserting compact wheel
The compact wheel is reinserted in the reverse
sequence of its removal.
When attaching the retaining strap to the
compact wheel, make sure the belt is
threaded through 2 rim openings, with one
unoccupied hole between them; otherwise, the
compact wheel could come loose in an acci-
dent.<
Preparing wheel change
1.Observe the safety precautions on
page103.
2.Secure the vehicle to prevent it from rolling:
place the wheel chock behind the front
wheel on the side of the vehicle opposite
the side being raised. If the vehicle is parked
on a downward slope, place the wheel
chock securely in front of the tire. If the
wheel must be changed on a surface with
a more severe slope, take additional pre-
cautions to secure the vehicle from rolling.
3.Loosen the lug bolts by a γ turn.
Jacking up vehicle
1.Position the vehicle jack at the jacking point
closest to the wheel so that the entire sur-
face of the jack base perpendicularly con-
tacts the ground under the jacking point.
The vehicle jack is designed for
changing wheels only. Do not attempt
to raise another vehicle model with it or to
raise any load of any kind. To do so could
cause accidents and personal injury.<
