General driving notes
Antilock Brake System
Brake system
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Hydroplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as hydroplaning
or aquaplaning. It is characterized by a
partial or complete loss of contact
between the tires and the road surface.
The ultimate results are loss of steering
and braking control.<
The conceptThe Antilock Brake System ABS keeps
the wheels from locking during braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply max-
imum pedal pressure Ð panic stop.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.
Brake fluid levelIf the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest
BMW Sports Activity Vehicle
center. Here increased pressure on the
brake pedal may be required, and slight
pulling to the side and longer braking
distances may result. Please remember
to adapt your driving style accord-
ingly.<

Information for your safety The factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle when
used correctly.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety which depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a
frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW. Check tire
inflation pressures Ð including the spare
wheel Ð regularly, refer to page 26, at
least every two weeks and before
beginning a longer trip. If this is not
done, incorrect tire pressures can
cause driving instability and tire
damage, ultimately resulting in an
accident.<
Tire tread Ð Tire damage Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
Tread depth should not be allowed to
go below 0.12 in/3 mm, even though,
the legally specified minimum tread
depth, for example in Europe, is only
0.063 in/1.6 mm. Below a tread depth
of 0.12 in/3 mm there is an increased
risk of hydroplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.
Tread wear indicators, refer to arrow,
are embedded around the tire circum-
ference in the base of the tire tread.
Their locations are indicated on the tire
sidewall with TWI Ð Tread Wear Indi-390de331
cator. At a tread depth of 0.063 in/
1.6 mm these indicators, signal that the
tires have reached the legally permis-
sible wear limit.
Do not drive on a deflated Ð flat Ð
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation, e.g. caused
by contact with curbs, etc., can indicate
a flat tire or some other vehicle mal-
function. This is also true for irregulari-
ties in the vehicle's handling character-
istics, such as a pronounced tendency
to pull to the left or right. Should this
occur, respond by immediately
reducing your speed.

Tire condition Tire replacement Proceed carefully to the nearest
BMW Sports Activity Vehicle center or
professional tire center, or have the
vehicle towed in to have it, its wheels
and tires inspected.
Tire damage up to and including blow-
outs can endanger the lives of both the
vehicle occupants and other road
users.<
DOT Quality GradesTread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.< Tread wearThe tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled condi-
tions on a specified government test
course.
For example, a tire graded 150 would
wear one and one-half Ð 1g Ð times as
well on the government course as a tire
graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.
TractionThe 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 speci-
fied government 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 braking traction tests, and does
not include acceleration, cornering,
hydroplaning, or peak traction charac-
teristics.<

136n
Tire replacement TemperatureThe temperature grades are A, the
highest, B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive tem-
perature can lead to a sudden flat tire.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Car Safety Standard No. 109.
Grades B and A represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
The temperature grade for this tire
is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible a tire failure.<
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
Tire age BMW recommends the replacement of
all tires Ð i.e. also of the spare tire, inde-
pendently of actual wear Ð when the
tires are no more than 6 years old, even
if a tire life of 10 years is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 2602 indicates that the tire was
manufactured in week 26 of 2002.

Wheel and tire combinations The right choice
Use only wheels and tires
approved by BMW for the corre-
sponding vehicle model, as otherwise
the tires may make contact with the
body as the result of tolerances despite
the same nominal size being used,
resulting in serious accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
BMW tests certain tire brands for each
tire size, classifies them as road-safe
and approves them. Consult your
BMW Sports Activity Vehicle center for
more information. Observe any regula-
tions applicable in the country of use,
e.g. requiring entry in the vehicle docu-
ments.
The correct wheel and tire combi-
nation affects different systems
such as ABS, ATC and DSC. The func-
tion of these systems is impaired if
improper wheel and tire combinations
are used.
For this reason, use only tires of the
same brand and tread pattern on the
vehicle and, for example, restore the
approved wheel and tire combination
following a flat tire as soon as
possible.<
The use of rims and lug bolts that
do not meet the specifications of
the original factory-installed equipment
will affect the safe operation of your
vehicle and may cause an accident and
personal injury.
Never mix tires of different design, such
as steel-belted radials with radial bias
belted or bias-ply tires, etc. Mixing tire
types will adversely affect roadholding
and can lead to loss of vehicle
control.<
Storage Store wheels or tires in a cool, dry
place, protecting them against light
whenever possible. Protect the tires
against contact with oil, grease and
fuel.

Winter tires Snow chains
*
Choosing the right tire BMW recommends winter tires Ð M+S
radial tires Ð for operation under
inclement winter driving conditions.
While so-called all-season tires with
M+S designation provide better winter
traction than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires.
Do not exceed specified
maximum speeds
Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW Sports
Activity Vehicle center will be glad to
assist you with both their expertise and
the proper equipment for your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in/4 mm, and should thus
be replaced.
Comply with the specified tire inflation
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. The use of narrow-link BMW
snow chains is approved only in pairs
on the rear wheels and only with the
following tire sizes.
BMW X5 4.6is: 255/55 R18
All other models: 235/65 R 17.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
