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
page 72, making sure that objects can-
not penetrate the partition net
>For very heavy cargo when the rear seat
is not occupied, secure each safety belt
in the opposite buckle.
Cargo, securing
>Use the luggage net* to hold down
small and lightweight luggage and
cargo, refer to page 72
>For larger and heavier pieces, load
securing equipment
* is available from
your BMW Sports Activity Vehicle Cen-
ter. Lashing eyes for attaching these
heavy-duty straps have been provided
in your vehicle's luggage compartment,
refer to page 73
>Read and comply with the information
enclosed with the load-securing
devices.Always position and secure the load
correctly. 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 page 116, as excessive
loads can pose a safety hazard, and may
also place you in violation of freeway safety
laws.
You should never transport heavy or hard
objects unsecured in the passenger com-
partment, as they could fly around and
pose a safety hazard to the vehicle's occu-
pants even during abrupt braking or eva-
sive maneuvers .<
Roof-mounted luggage
rack*
Because roof racks raise the vehicle's cen-
ter 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 vehicle weight or the axle
loads when loading the rack.
You can find the specified weights in the
Technical data section on page 116.
Make sure that the load is not too heavy,
and that it does not extend outward to
beyond the limits of the loading surface.
Always load the heaviest pieces first Ð on
the bottom. Be sure that adequate clear-
ance is maintained for raising the glass
roof, 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 gen-
tly.

Things to remember when driving
80
Driving on bad roads
Your BMW 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 bad roads, there
are a few points which you should strictly
observe Ñ 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 circum-
stances
>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 pages 94 and 96
>For very steep downhill driving, use Hill
Descent Control HDC, refer to page 51.
Driving off is possible on upward
inclines of up to 33%.
The permitted side inclination is 50 %
>While driving, watch carefully for obsta-
cles 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
>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 walk-
ing speed and do not stop.
After leaving the water, press on the
footbrake gently several times while
driving at a low speed. The brake appli-
cations will help to dry the brakes, thus
preventing a reduction in braking per-
formance caused by the moisture. For cleaning the handbrake, apply the
lever slightly at approx. 25 mph/40 km/
h and continue 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 pre-
serve the road safety of your BMW:
>Clean the heavy dirt from the body
>Clean mud, snow, ice and other materi-
als from the wheels and tires. Check the
tires for damage.

Tire inflation pressure
Information for your safety
It is not merely the tire's service life, but
also driving comfort and Ð to a great extent
Ð driving safety that depend on the condi-
tion of the tires and the maintenance of the
specified tire pressure.
Check the tire inflation pressure regu-
larly and correct it if necessary,
including compact wheel: at least every
two weeks and before beginning a longer
trip. If you fail to observe this precaution
you may be driving on tires with incorrect
tire pressures, a condition that cannot only
compromise your vehicle's driving stability,
but also lead to tire damage and the risk of
an accident.
Do not drive with a depressurized, i.e. flat
tire. 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.<
Checking the pressure
Only check tire inflation pressure when the
tires are cold. That 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 infla-
tion pressure increases.
After correcting the inflation pressure(s),
always reinitialize the Flat Tire Monitor,
refer to page 53.
Checking inflation pressure
The inflation pressures for your standard
tires can be seen on the door pillar when
you open the driver's door.
After correcting the inflation pres-
sure(s), always reinitialize the Flat Tire
Monitor, refer to page 53.<
Inflation pressure for other tire sizes
The table below provides all the correct
inflation pressures for the specified tire
sizes at ambient temperature.
For correct identification of the right
tire inflation pressure for your tires,
observe the specifications for the corre-
sponding tire size.<

Tire identification marks
Knowledge of the labeling on the side of
the tire makes it easier to identify and
choose the right tires.
Tire size
Speed code letter
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 Transport.
DOT code:
Tire age
The tire's date of manufacture is indicated
on the sidewall:
DOT ... 3603 indicates that a tire was man-
ufactured in week 36 of the year 2003.
BMW recommends that you replace all
tires after 6 years at the latest, indepen-
dently of the fact that tires can reach an age
of 10 years.
Uniform Tire Quality Grading
Quality grades can be found where appli-
cable on the tire sidewall between tread
shoulder and maximum section width.
For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.<
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course.
For example, a tire graded 150 would wear
one and one-half (1 g) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.
Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified govern-
ment test surfaces 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 brak-
ing traction tests, and does not include
acceleration, cornering, hydroplaning, or
peak traction characteristics.<
Temperature
The temperature grades are A Ð the
highest Ð B, and C, representing the tire's e.g.
