The individual vehicle
On purchasing your BMW, you have
decided in favor of a model with individual-
ized equipment and features. This Owner's
Manual describes the entire array of
options and equipment available with a
specific BMW model.
Please bear in mind that the manual may
contain information on accessories and
equipment that you have not specified for
your own vehicle. Sections describing
options and special equipment are marked
by asterisks
* to assist you in identifying
possible differences between the descrip-
tions in this manual and your own vehicle's
equipment.
Should your BMW be equipped with fea-
tures or accessories not described in this
manual, please consult the enclosed Sup-
plementary Owner's Manual(s).
Editorial notice
BMW pursues a policy of continuous,
ongoing development that is conceived
to ensure that our vehicles continue to
embody the highest quality and safety
standards combined with advanced, state-
of-the-art technology.
For this reason, it is possible that the fea-
tures described in this Owner's Manual
could differ from those on your vehicle. Nor
can errors and omissions be entirely ruled
out. You are therefore asked to appreciate
that no legal claims can be entertained on
the basis of the data, illustrations or
descriptions in this Owner's Manual.

For your own safety
Fuels
Use unleaded gasoline only.
Fuels containing up to and including
10 % ethanol or other oxygenates with
up to 2.8 % oxygen by weight – that is,
15 % MTBE or 3 % methanol plus an equiv-
alent amount of co-solvent – will not void
the applicable warranties with respect to
defects in materials or workmanship. Field
experience has indicated significant differ-
ences in fuel quality – volatility, composi-
tion, additives, etc. – among gasolines
offered for sale in the United States and
Canada. The use of poor-quality fuels may
result in drivability, starting and stalling
problems, especially under certain environ-
mental conditions such as high ambient
temperature and high altitude.
Should you encounter drivability problems
which you suspect could be related to the
fuel you are using, we recommend that you
respond by switching to a recognized high-
quality brand.
Failure to comply with these recommenda-
tions may result in unscheduled mainte-
nance.
Follow the relevant safety rules when you
are handling gasoline.<
Maintenance and repair
Advanced technology, e. g. the use of
modern materials and high-perfor-
mance electronics, requires specially
adapted maintenance and repair methods.
Therefore, only have corresponding work
on your BMW carried out by a BMW center
or a workshop that works according to
BMW repair procedures with correspond-
ingly trained personnel. If work is carried
out improperly there is a danger of conse-
quential damage and the related safety
risks.<
Parts and accessories
For your own safety, use genuine
parts and accessories approved by
BMW.
When you purchase accessories tested
and approved by BMW and Genuine BMW
Parts, you simultaneously acquire the
assurance that they have been thoroughly
tested by BMW to ensure optimum perfor-
mance when installed on your vehicle.
BMW warrants these parts to be free from
defects in material and workmanship.
BMW will not accept any liability for dam-
age resulting from installation of parts and
accessories not approved by BMW.
BMW cannot test every product made by
other manufacturers to verify if it can be
used on a BMW safely and without risk to
either the vehicle, its operation, or its occu-
pants.
Genuine BMW Parts, BMW Accessories
and other products approved by BMW,
together with professional advice on using
these items, are available from all BMW
centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones – including operation of
any portable phone from within the vehicle
without using an externally mounted
antenna – or transceiver equipment, for
instance, CBs, walkie-talkie, ham radio or
similar accessories, may cause extensive
damage to the vehicle, compromise its
safety, interfere with the vehicle's electrical
system or affect the validity of the BMW
Limited Warranty. Refer to your BMW cen-
ter for additional information.<
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any automo-
tive repair establishment or individual using
any certified automotive part.<
