2004 BMW 320i maintenance

Congratulations, and thank you for choosing a BMW.
Thorough familiarity with your vehicle will provide you with enhanced control and
security when you drive it. Therefore we have one request:
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
operating safety while simultaneously helping you to maintain your BMW's value
throughout an extended service life. For additional information refer to the supple-
mental manuals.
This Owner's Manual should be considered a permanent part of this vehicle. It
should stay with the vehicle when sold to provide the next owner with important
operating, safety and maintenance information.
We wish you an enjoyable driving experience.

Notes

Your individual vehicle

On purchasing your BMW, you have
decided in favor of a model with individ-
ualized 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
that you might not have chosen for your
vehicle. You can easily identify any dif-
ferences with the aid of the asterisk
used to identify all optional equipment
and accessories.
If your BMW features equipment which
is not described in this Owner's Manual
such as a car radio or telephone, Sup-
plementary Owner's Manuals are
enclosed. We ask you to read these
manuals as well.

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
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
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.

Notes

Maintenance and repair

Advanced technology, e.g. the
use of modern materials and high-
performance electronics, requires spe-
cially adapted maintenance and repair
methods. Therefore, only have corre-
sponding work on your BMW carried
out by a BMW center or a workshop
that works according to BMW repair
procedures with correspondingly
trained personnel. If work is carried out
improperly there is a danger of conse-
quential damage and the related safety
risks.

Parts and accessories

Important safety information!
For your own safety, use genuine
parts and accessories 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 thor-
oughly tested by BMW to ensure opti-
mum performance when installed on
your vehicle.
BMW warrants these parts to be free
from defects in material and workman-
ship.
BMW will not accept any liability for
damage resulting from installation of
parts and accessories not approved by
BMW.
BMW cannot test every product on the
market to determine whether it can be
used on a BMW safely and without risk
to either the vehicle, 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 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 cellular phone
from within the vehicle without using an
externally mounted antenna – or trans-
ceiver equipment such as a CB, walkie-
talkie, ham radio or similar, may cause
extensive damage to the vehicle, com-
promise 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 luggage compartment
with anyone inside the vehicle. Refer to
the Owner's Manual for more details.

<

Maintenance, replacement, or
repair of the emission control
devices and systems may be performed
by any automotive repair establishment
or individual using any certified auto-
motive part.
