General malfunctions
The BMW CD changer is optimized for opera-
tion in the vehicle. It may react more sensitively
to defective CDs than devices intended for sta-
tionary use.
If a CD cannot be played back, first check to
make sure it has been correctly inserted.
Humidity
High humidity can fog the CD or the focusing
lens for the laser beam, temporarily preventing
playback.
Malfunctions with individual CDs
If malfunctions occur only with particular CDs,
this can be due to one of the following causes.
Home-recorded CDs
Malfunction sources in home-recorded CDs
include, for example, inconsistent data origina-
tion and recording processes as well as low
quality or pronounced aging of the blanks used.
Only write on CDs with a marker especially
designed for this purpose.
Damaged CDs
Avoid finger prints, dust, scratches, and mois-
ture.
Store CDs in a sleeve.
Do not expose CDs to temperatures above
1227/506, high humidity or direct sunlight.
CDs with copy protection
Manufacturers often provide CDs with copy
protection. This can prevent or limit the play-
back of these CDs.

Tire coding
Knowledge of the labeling on the side of the tire
makes it easier to identify and choose the right
tires.
Tire size
Speed rating
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...1007 means that the tire was manufac-
tured in the 10th week of 2007.
BMW recommends that you replace all tires –
including the spare – after a maximum of 6 years, even though the tires may have a theo-
retical service life of up to 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, service practices and differ-
ences 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 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.

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire's resis-
tance to the generation of heat and its ability to
dissipate heat when tested under controlled
conditions 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 temperature 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 Vehi-
cle 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 sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC Run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page205.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread depth,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm, there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety, you should
always have such tires replaced.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low profile tires make wheels,
tires, and suspension parts more susceptible to
road hazards and consequential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. Drive carefully to the nearest
BMW center or tire shop that works according
to BMW repair procedures with correspond-
