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. 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
Motor 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, under-inflation, or
excessive loading, either separately or
in combination, can cause heat buildup
and possible tire failure. better winter driving properties than
summer tires.
Tire conditionWheel/tire damageInspect your tires frequently for signs of
damage, foreign objects and tread
wear, and check tread depth.
Due to low-profile tires, please
note that wheels, tires and sus-
pension parts are more susceptible to
road hazard and consequential dam-
ages.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect.
This type of problem can be caused by
contact with curbs, etc. This is also true
for irregularities in the vehicle's han-
dling characteristics, such as a pro-
nounced tendency to pull to the left or
right.
Should this occur, respond by immedi-
ately reducing your speed. Proceed
carefully to the nearest BMW center or
professional tire center, or have the
vehicle towed there. Tire damage, up to
and including blowouts, can endanger
the lives of both the vehicle occupants
and other road users.<

required technical background. If you
are not familiar with the regulations to
be observed, have your vehicle ser-
viced only by a BMW center or a shop
that works according to BMW require-
ments with appropriately trained per-
sonnel. Work that is improperly carried
out could result in consequential dam-
age and pose safety hazards.<

Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
Before checking the engine oil level
after topping up, restart the engine and
allow it to run to obtain a correct dis-
play. Then proceed as described under
Checking the oil level.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, thoroughly
wash any areas of skin that come into
contact with oil using soap and water.
Store oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.<
Recommendation: have the oil changed
by your BMW center.
Specified engine oilsThe quality of the engine oil is
extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain grades of engine oil.
Use only oils approved for your vehicle
model.
Ask your BMW center for details
concerning oils that have been
approved. You can also call BMW of
North America toll-free at 1-800-831-
1117 or visit this website:
www.bmwusa.com to obtain this infor-
mation.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other synthetic oils for topping up
between oil changes. The following
data must appear on the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or
SAE 10W-40

OBD interface socketThe Onboard Diagnostic OBD interface
socket is located on the left of the
driver's side under the instrument panel
and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle"s
lifetime. The system monitors emission-
related components and systems for
deterioriation and malfunction.
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Display in Canadian models for
the malfunction described
above.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission control
components, especially the catalytic
converter.
When the fuel filler cap is not
properly tightened, the OBD sys-
tem can detect the vapor leak and the
indicator will light up. If the filler cap is
subsequently tightened, the indicator
should go out within a few days.<
Event data recordersYour vehicle may be equipped with one
or more sensing and diagnostic mod-
ules or a recording device capable of
recording or transmitting certain vehicle
data or information. In addition, if you
