The BMW Maintenance System has
been designed as a reliable means of
ensuring that our customers enjoy
optimal vehicle safety and reliability
with only minimum effort and expense.
Please keep in mind that regular service
not only plays a vital role in ensuring
continued vehicle safety, but also plays
a significant role in maintaining your
vehicle's resale value.

Service Interval DisplayOptimal maintenance intervals are
calculated by using advanced tech-
nology; these then are indicated in the
Service Interval Display. While conven-
tional systems rely on distance traveled
alone to determine when service is due,
the BMW Maintenance System has for
years considered the actual conditions
under which the vehicle operates,
because miles can be traveled in many
different ways:
From the maintenance point of view,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
equivalent to the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System, which
is based on operating conditions,
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those drivers
who put significantly less than
6,000 miles (10,000 km) on their vehicle
anually should have the engine oil
changed at least every two years since
oil deteriorates over time, regardless of
use.
Service Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
Have your BMW center perform
maintenance and repair work.
Your BMW center is always informed on
the latest maintenance work and repair
techniques and equipped with the
required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models).
These entries are your proof of regular
vehicle maintenance and the basis for
warranty claims.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5. Fill the fuel tank completely to
prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1. Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).

OBD interface socket The Onboard Diagnostic (OBD) inter-
face socket is located on the driver's
side at the bottom of the instrument
panel and under a cover. The cover has
the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system throughout the
vehicle's lifetime by monitoring emis-
sions-related components and systems
for deterioration and malfunction.520de130
An illuminated indicator informs
you of the need for service, but
not of the need to stop the
vehicle. However, the systems should
be checked by your BMW center at the
earliest possible opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission controll
components, especially the catalytic
converter.
Service Engine Soon warning
lamp for Canadian models.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.<
