2004 BMW 3 SERIES ignition

Maintenance System
The BMW Maintenance System has been
devised with the following objectives: to
maximize vehicle safety, reliability, and resale
value by minimizing breakdowns resulting from
wear, and minimizing cost and inconvenience
by computing maintenance intervals based
upon the specific manner in which each
individual vehicle is driven.
Maintenance intervals on motor vehicles have
conventionally been specified based upon
accumulated mileage. However, the type of
driving conditions has a major influence on
routine maintenance requirements; distance
traveled is only one of the significant factors.
A vehicle driven for 50,000 miles of short trips
in the city with numerous cold starts, pro-
longed periods of idling, stop-and-go driving,
and high engine speeds during acceleration
requires more frequent maintenance
intervals than a vehicle driven for 50,000
miles for long distances at low engine
speeds primarily at operating temperature.
The advanced technologies at BMW have led
to the development of the unique BMW service
interval indicator which computes the actual
optimum maintenance requirements based
not only upon the accumulated mileage, but
taking into account important factors such as
engine coolant temperatures, high or low
engine speeds, short or long trip driving, and
number of vehicle starts. The maintenance
interval may therefore be maximized with
considerable savings to owners of vehicles
subjected to light duty.
The service interval indicator consists of a
mileage reading, and the inscriptions “OIL
SERVICE” and “INSPECTION”.
Whenever the ignition is switched on, the
display shows the next scheduled type of
service and the remaining distance until the
service should be performed. The distance is
based on your driving style.If the maintenance interval has been ex-
ceeded, a “—” symbol reminds you of the
urgent need for servicing. In the interests of
road safety and reliability, you should avoid
driving your BMW when the “—” symbol is
showing, and have the essential maintenance
work performed without delay.
After each maintenance is performed the service
indicator is reset in order to compute the next
service interval.
If the service interval indicator displays an
illogical reading, or if there is no display, consult
a BMW center.
If the speedometer, tachometer or coolant
temperature gauge should develop a fault, the
service interval indicator will probably cease to
operate correctly as well, since it depends on
correct speed, distance and temperature
readings. The fault must be located and rectified
by a BMW center.
A detailed list of all maintenance operations
included in each of the elements of the BMW
Maintenance System is found on pages 5-8.
These elements are as follows:

of the emission control systems for
optimum vehicle performance and fuel
economy.

Oxygen Sensor Service: The oxygen sensor deteriorates strictly on a mileage basis and must
therefore be replaced to maximize vehicle fuel economy and minimize exhaust pollution.
The mileage interval varies according to individual driving conditions and is determined by the
service interval indicator.

The California Air Resources Board and BMW
of North America (BMW NA) are pleased to
explain the emission control system warranty
on your 2004 vehicle. In California, new motor
vehicles must be designed, built and
equipped to meet the State’s stringent anti-
smog stan-dards. BMW NA must warrant the
emission control system on your vehicle for the
periods of time listed below provided there has
been no abuse, neglect or improper
maintenance of your vehicle.
Your emission control system may include
parts such as the fuel injection system, the
ignition system, catalytic converter, and engine
computer. Also included may be hoses, belts,
connectors and other emission-related
assemblies.
Where a warrantable condition exists, BMW NA
will repair your vehicle at no cost to you
including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage:
– For 3 years or 50,000 miles whichever
occurs first:
