Your individual vehicle
O n b u y i n g y o u r B M W , y o u h a v e d e c i d e d i n f a v o r
of a model with individualized equipment and
features. This Owner's Manual describes all
models and equipment that BMW offers within
the same group.
We hope you will understand that equipment
and features are included which you might not
have chosen for your vehicle. Any differences
can easily be identified since all optional acces-
sories and special equipment are marked with
an asterisk
*.
If your BMW features equipment not described
in this Owner's Manual, please observe the
enclosed supplementary Owner's Manuals.
Status at time of printing
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. In
exceptional cases, the features described in
this Owner's Manual could therefore differ from
those on your vehicle.

For your own safety
Maintenance and repair
Advanced technology, e. g. the use of
modern materials and high-performance
electronics, requires specially adapted mainte-
nance 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 cor-
respondingly trained personnel. If work is car-
ried out improperly there is a danger of conse-
quential damage and the related safety risks.<
California Proposition 65 warning
California laws require us to state the following
warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior fur-
nishings in a vehicle, contain or emit chemicals
known to the State of California to cause cancer
and birth defects and reproductive harm. In
addition, certain fluids contained in vehicles and
certain products of component wear contain or
emit chemicals known to the State of CA to
cause cancer and birth defects or other repro-
ductive harm.
Battery posts, terminals and related accesso-
ries contain lead and lead compounds. Batter-
ies also contain other chemicals known to the
State of California to cause cancer. Wash your
hands after handling.
Used engine oil contains chemicals that have
caused cancer in laboratory animals. Always
protect your skin by washing thoroughly with
soap and water.<
Parts and accessories
For your own safety, use parts and acces-
sories approved by BMW.
When you purchase accessories tested and
approved by BMW and Original BMW Parts, you
simultaneously acquire the assurance that they
have been thoroughly tested by BMW to ensure
optimum performance 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 damage
resulting from installation of parts and accesso-
ries 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 vehi-
cle, its operation, or its occupants.
Original BMW Parts, BMW Accessories and
other products approved by BMW, together
with professional advice on using these items,
are available from all BMW retailers.
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 cellular
phone from within the vehicle without using an
externally mounted antenna, or transceiver
equipment, e.g. C.B., walkie-talkie, ham radio or
similar, 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. See your
BMW center for additional information.
Do not use key or remote control to lock doors
or trunk with anyone inside the vehicle. Refer to
the Owner's Manual for more details.<
Maintenance, replacement or repair of
the emission control devices and sys-
tems may be performed by any automotive
repair establishment or individual using any cer-
tified automotive part.<
