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, i.e. 15% MTBE or
3% methanol plus an equivalent amount of
co-solvent Ð will not void the applicable
warranties respecting defects in materials
or workmanship. Field experience has indi-
cated significant differences in fuel quality Ð
i.e. volatility, composition, additives, etc. Ð
among gasolines offered for sale in the
United States and Canada. The use of
poor-quality fuels may result in driveability,
starting and stalling problems especially
under certain environmental conditions,
such as high ambient temperature and high
altitude.
Should you encounter driveability prob-
lems 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 Sports
Activity Vehicle Center or a workshop that
works according to BMW repair proce-
dures with correspondingly trained person-
nel. If work is carried out improperly, there
is a danger of consequential 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-
ages 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
Sports Activity Vehicle Centers.
Installation and operation of non-BMW
approved accessories such as alarms,
radios, amplifiers, radar detectors, wheels,
suspension components, brake dust
shields, telephones Ð including operation of
any portable phone from within the vehicle
without using an externally mounted
antenna Ð 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. See your BMW Sports
Activity Vehicle Center for additional infor-
mation.

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.
