2005 BMW X3 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 mainte-
nance 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 require-
ments; 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, prolonged 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 System 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.
(Typical Display) 32 88 02 30The Service Indicator consists of five green,
one yellow and one red Iight-emitting-diodes
(LEDs) and the inscriptions “OIL SERVICE”
and “INSPECTION”.
Whenever the ignition is switched on, up to
five green LEDs will light up, depending on
the amount of use the vehicle has had since
the last maintenance service and your driving
style. As the number of illuminated green LEDs
decreases, this is an indication that the next
service is almost due and helps you to make
the necessary arrangements on a timely basis.
The green LEDs disappear when the engine
is started.
Notification that maintenance is required is
indicated with the illumination of the yellow
LED and accompanying inscription. These will
remain illuminated with the ignition on.
If the maintenance interval has been exceeded,
the red LED will light up in addition to the
yellow one to remind you of the urgent need for
servicing. In the interests of road safety and
reliability, you should avoid driving your BMW
when the red LED signal 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.
The green LEDs which then light up with the
ignition show you the interval before the next
maintenance is due.
If the service indicator displays an illogical
reading, for instance the green and red LEDs
at the same time, or if there is no display,
consult an authorized BMW SAV center.
If the speedometer, tachometer or coolant
temperature gauge should develop a fault, the
service 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 an authorized BMW SAV center.

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 2005 SAV. In California, new motor
vehicles must be designed, built and equipped
to meet the State’s stringent anti-smog
standards. BMW NA must warrant the
emission control system on your SAV for the
periods of time listed below provided there has
been no abuse, neglect or improper mainte-
nance of your SAV.
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 SAV at no cost to you
including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage:
– For 3 years or 50,000 miles whichever
occurs first:
1. If your SAV fails a Smog Check inspection,
all necessary repairs and adjustments will
be made by BMW NA to ensure that your
SAV passes the inspection. This is your
emission control system PERFORMANCE
WARRANTY.
