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.

>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.
For cleaning 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.
Please bear the following points in mind after
driving on poor roads, in order to preserve the
road safety of your BMW:
>Clean the heavy dirt from the body.
>Clean mud, snow, ice and other materials
from the wheels and tires. Check the tires
for damage.

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.<

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. flat tires. A flat tire
will seriously impair your vehicle's handling and
braking response. Attempts to drive on a flat tire
can lead to loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages51,
52.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve an optimal driving
comfort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

Q = up to 105 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
DOT code:
Tire age
The tire's date of manufacture is indicated on
the sidewall:
DOT ... 0506 indicates that a tire was manufac-
tured in week 5 of the year 2006.BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width.
For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half (1γ) times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, and may devi-
ate significantly from the norm due to variations
in driving habits and service practices as well as
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
These grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.< e.g. 235/50 R 18 97 V
