Please take the time to read this Owner's Manual and familiarize yourself with the
information that we have compiled for you before starting off in your new BMW. The
manual contains important data and instructions intended to assist you in obtaining
maximum satisfaction from your BMW's unique array of advanced technical fea-
tures. It also contains information on vehicle maintenance designed to enhance

throughout an extended service life. For additional information refer to the supple-

Notes

Status at time of printing

BMW pursues a policy of continuous,
ongoing development 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, the features 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
claims can be recognized on the basis
of the data, illustrations or descriptions
in this Owner's Manual.

For your own safety

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
equivalent amount of co-solvent – will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality – volatility, composition, addi-
tives, etc. 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 recom-
mendations may result in unscheduled
maintenance.
Obey all applicable safety rules when
handling gasoline.

used on a BMW safely and without risk
to either the vehicle, its operation, or its
occupants.
