Antilock Brake System (ABS) should adapt road speed to the road
conditions.
On road surfaces that have a loose sur-
face layer on a firm base with good
traction (on gravel, deep sand or snow,
for example), braking distances may be
longer than with locked wheels.This is
also true if snow chains are mounted.
However, ABS continues to provide en-
hanced vehicle stability and steering re-
sponse under these conditions. Information for your safety Not even ABS can suspend the laws of
physics. ABS alone cannot prevent
accidents when the brakes are applied
without an adequate safety distance
between vehicles, if the vehicle is
driven with excessive speed, or if aqua-
planing occurs. Responsibility for these
types of situations remains in the hands
(and at the feet) of the driver. You
should never allow the added safety of
ABS to lull you into a false sense of
security, or mislead you into taking
increased risks that could affect your
own safety and that of others.
Do not make any modifications to
the ABS system.
Service procedures on ABS are to be
performed by authorized technicians
only.<
Cornering Brake Control (CBC) CBC is an advanced engineering de-
sign of the ABS. When braking during
cornering with high lateral accelera-
tion, or when braking during a lane
change, vehicle stability is further im-
proved and the steering response is
enhanced. Electronic Brake Force Distribu-
tion (EBV) EBV governs brake application pres-
sure at the rear wheels to achieve sta-
ble brake response.
If the EBV fails (refer to the next
page), avoid full or "panic" brake
applications. Full or panic brake appli-
cations can result in overbraking at the
rear axle, and braking stability is no
longer ensured.<
Dynamic Brake Control (DBC)

If you apply the brakes rapidly, this sys-
tem automatically produces the maxi-
mum braking force boost and thus
helps to achieve the shortest possible
braking distance during "panic stops."
All of the benefits of the ABS system
are exploited under these circum-
stances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
In the event of a malfunction,
the yellow warning lamp comes
on. Have the system checked
and repaired at your BMW cen-
ter as soon as possible.
Refer to the "Information for your
safety" covering the ABS system.
This information also applies in general
for DBC.<

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.
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 signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures Ð
including the spare wheel Ð regu-
larly, 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 depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base indicate that the legally-
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road. 390de331
Do not drive on a deflated (flat)
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 ex-
ceeded. 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 air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect,
as can variations in normal vehicle re-
sponse, such as a pronounced ten-
dency to pull to the left or right. Should
this occur, respond by immediately re-
ducing your speed and carefully pro-
ceeding to the nearest BMW center or
professional tire center, or having the
vehicle towed in to have it and its tires
inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<

Tire replacement To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. BMW tests and approves
wheel/tire combinations. Refer to
page 130. DOT Quality Grades Treadwear
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.< Treadwear The treadwear 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 (1 1/2) 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.
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 speci-
fied government test surfaces of as-
phalt 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, hy-
droplaning, or peak traction character-
istics.< Temperature The 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 sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Mo-
tor Vehicle 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 ex-
cessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.< Uniform Tire Quality Grading Quality grades can be found where ap-
plicable on the tire sidewall between
tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA
Temperature A
Do not use retreaded tires, since
driving safety may be impaired by
their use. This is due to the possible
variations in casing structures and, in
some cases, to their extreme age,
which can lead to a decrease in their
durability.<

Winter tires Snow chains
*
Choosing the right tire BMW recommends special winter tires
(M+S radial tires) for driving in adverse
winter road conditions. While the All-
Season tires with M+S designation that
are mounted as standard equipment
provide better winter traction than sum-
mer tires, they generally do not achieve
the performance of winter tires.
For safe tracking and steering re-
sponse, install winter tires made by the
same manufacturer having the same
tread configuration on all four wheels.
Mount only winter tires approved by
BMW. Any BMW center will be glad to
provide you with information for select-
ing the best winter tires for your partic-
ular driving conditions.
Do not exceed specified
maximum speeds
Never exceed the maximum
speed for which winter tires are
rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressure Once winter tires wear to a tread depth
below 0.16 in (4 mm), their performance
under winter driving conditions deterio-
rates noticeably. Worn tires should
therefore be replaced for safety consid-
erations.
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. Storage Store tires in a cool, dry place, away
from light whenever possible. Protect
the tires against contact with oil, grease
and fuel.
The use of narrow-link BMW snow
chains is approved only in pairs on the
rear wheels and only with tire size
235/65 R 17. Comply with all manufac-
turer's safety precautions when mount-
ing the chains.

Engine oil Specified engine oils The quality of the engine oil selected
has critical significance for the opera-
tion and service life of an engine. Based
on extensive testing, BMW recom-
mends only certain types of engine oil.
Use only approved "BMW High Perfor-
mance Synthetic Oil."
If you are unable to obtain "BMW High
Performance Synthetic Oil," you can
add small amounts of synthetic oil in
between oil changes. Use only oils with
the API SH specification or higher.
Ask your authorized BMW center
for details concerning the specific
"BMW High Performance Synthetic Oil"
or "synthetic oils" which have been ap-
proved.<
You can also call BMW of North Amer-
ica at 1-800-831-1117 or visit this web-
site: www.bmwusa.com to obtain this
information.
Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Brake fluid Vehicle IdentiÞcation No.
If the indicator lamp for the
brake hydraulic system appears
or if the CHECK BRAKE FLUID
warning appears in the Check
Control
*: the brake fluid level is
too low in the reservoir.
The brake fluid reservoir is located un-
der the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW center. Your
BMW center is familiar with the specifi-
cations for factory-approved brake
fluids (DOT 4).
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 123.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
an authorized BMW center. Refer also
to the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its original container and in a loca-
tion which is out of reach of children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety Ð and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.
Service Interval Display Advanced technology is employed to
calculate the optimal maintenance in-
tervals, which are then indicated in the
Service Interval Display. Conventional
systems rely solely on distance traveled
to determine when service is due. The
BMW maintenance system, on the 390us008
other hand, began many years ago to
take the actual conditions under which
the vehicle is driven into consideration.
After all, different drivers can accumu-
late mileage in very different ways.
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System in-
cludes the Engine Oil Service and In-
spections I and II.
Determining the maintenance intervals
according to the actual loads on the ve-
hicle covers every kind of operating sit-
uation. However, even those who drive
only short distances Ð significantly less
than 6,000 miles (10,000 km) annually Ð
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use. Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet (Cana-
dian models) For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-mation Booklet (US models) or the
Warranty and Service Guide (Canadian
models).
As a precaution against corrosion, it
might be a good idea to have the body
checked for damage from rocks or
gravel at the same time, depending
upon operating conditions.
Have your BMW center do the
maintenance and repair.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the re-
quired special tools. In addition, check-
ing parts known from experience to be
subject to wear is a permanent part of
the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide (Canadian
models).
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required for
warranty claims.<

Caring for your vehicle Caring for the vehicle finish Regular washing is a preventive mea-
sure against long-term effects from
substances that are harmful to the vehi-
cle's finish, especially if you drive your
vehicle in areas with high levels of air
pollution or aggressive natural sub-
stances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive sub-
stances. Failure to do so can lead to
changes in the paint's chemical struc-
ture or to discoloration. Gasoline spilled
during refueling, oil, grease and brake
fluid should always be cleaned away
immediately, as should bird droppings
(finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use clean-
ing fluid or alcohol with a clean cloth or
cotton pad to remove these stains. Re-
move tar spots with tar remover. After
cleaning, the affected areas should be
waxed to ensure continued protection.
Waxing your vehicle Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the sur-
face.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Paint damageYou can touch up small areas of dam-
age with BMW spray paint or a BMW
touchup stick.
The color code of your vehicle is pro-
vided on a tag on the right-hand panel
under the hood and on the first page of
the Service and Warranty Information
Booklet.
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. After a few days, polish
and protect the touched-in areas.
More extensive paint damage should
be professionally repaired in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with factory repair procedures.
