Maintenance
The BMW Maintenance
System
The BMW Maintenance System has been
designed as a reliable means of providing
maximum driving and operating safety –
and as cost-effectively for you as possible.
Please keep in mind that regular mainte-
nance is not only necessary for the safety
of your vehicle, but also plays a significant
role in maintaining the resale value of your
vehicle.
Service interval display
While conventional systems rely on dis-
tance traveled alone to determine when a
service is due, the BMW Maintenance Sys-
tem has taken the actual conditions under
which the vehicle is operated into consid-
eration for years, because miles can be
traveled in many different ways:
From a maintenance point of view,
62,000 miles / 100,000 km accumulated in
short-distance urban driving are not the
equivalent of the same distance covered at
moderate speeds in long-distance highway
travel.
The BMW Maintenance System includes
the Engine Oil Service and Inspections I
and II.
Determining the maintenance intervals
based on the actual loads on the vehicle
covers every kind of operating situation.
Minimal use drivers, who drive fewer than
6,200 miles / 10,000 km per year, should
nevertheless have the oil changed at least
every 2 years since engine oil deteriorates
over time, regardless of use.
Service and Warranty Information
Booklet for US models/Warranty and
Service Guide Booklet for Canadian
models
For detailed information on required main-
tenance items and the work involved,
please refer to the Service and Warranty
Information Booklet for US models or to the
Warranty and Service Guide Booklet for
Canadian models.
Depending on operating conditions, it may
be advisable to have the body checked for
damage from rocks or gravel as a precau-
tion against corrosion.
BMW recommends that you have your
BMW center perform the mainte-
nance and repair.
Check that the maintenance work is
recorded in the Service Manual. These
entries will serve as proof that the vehicle
has received regular maintenance.

Laws and regulations
California Proposition 65
warning
California laws require us to state the fol-
lowing warning:
Engine exhaust, some of its constitu-
ents, and certain vehicle components
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 vehi-
cles and certain products of component
wear contain or emit chemicals known to
the State of California to cause cancer and
birth defects or other reproductive harm.
Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash your hands after handling. Used
engine oil contains chemicals that have
caused cancer in laboratory animals.
Always protect your skin by washing thor-
oughly with soap and water.
<
OBD interface socket
The Onboard Diagnostic OBD interface
socket is located on the left of the driver's
side behind a specially marked cover
located beneath the instrument panel. The
cover has the letters OBD on it.
This interface makes it possible to access
data on emissions – related components
using special equipment.
If the Service Engine Soon indicator
lamp comes on either continuously
or intermittently, this indicates a
fault in the emissions-related electronic
systems. Although the vehicle remains
operational, you should have the systems
checked by your BMW center at the earli-
est possible opportunity.
The illuminated indicator informs you of the
need for service, not that you need to stop
the vehicle. However, the systems should
be checked by your BMW center at the
next opportunity.
If the indicator blinks or flashes, this indi-
cates a high level of engine misfire. Reduce
speed and contact the nearest BMW center
immediately. Severe engine misfiring over
even a short period of time can seriously
damage emission control system compo-
nents, especially the catalytic converter.
Service Engine Soon
warning lamp for Canadian
models.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator will light up.
If the fuel filler cap is then tightened, the
indicator will usually go out after a short
period of time.

Lamps and bulbs
The lamps and bulbs make essential contri-
butions to the safety of your vehicle. There-
fore, comply fully with the following instruc-
tions during bulb replacement. If you are
not familiar with the procedures, BMW rec-
ommends that you have your BMW center
carry out the work.
Do not touch the glass portion of a
new bulb with your bare hands since
even small amounts of impurities burn into
the surface and reduce the service life of
the bulb. Use a clean cloth, paper napkin or
a similar material, or hold the bulb by its
metallic base.
<
A replacement bulb set is available from
your BMW center.
Before working on the electrical sys-
tem, switch off the electrical acces-
sory you are working on or disconnect the
cable from the negative terminal of the bat-
tery. Failure to observe this precaution
could result in short circuits.
To prevent injuries and damage, always
comply with any instructions provided by
the bulb manufacturer.

concerning the battery. Since the battery is
absolutely maintenance-free, the following
statements are for your information only.
<
Do not disconnect the battery cables
when the engine is running. Discon-
necting the battery cables when the engine
is running will cause a voltage surge which
will damage the vehicle's onboard elec-
tronics.
<
Indicator lamp
The indicator lamp for the battery
charge current lights up:
The battery is no longer being
charged. The alternator drive belt is defec-
tive or there is a malfunction in the charging
circuit of the alternator. Please contact the
