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 incon-
venience by computing maintenance inter-
vals 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, driving
conditions have 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,
prolonged periods of idling, stop-and-go
driving, and high engine speeds during
acceleration requires more frequent mainte-
nance intervals than a vehicle driven for
50,000 miles for long distances at low
engine speeds primarily at operating temper-
ature.
The advanced technologies at BMW have
led to the development of the unique BMW
Condition Based Service System (CBS)
which computes the actual optimum mainte-
nance requirements based not only upon the
accumulated mileage, but taking into
account important factors such as high or
low engine speeds, short or long trip driving,
and condition of the engine oil and brake
pads.
The BMW Maintenance
System
Condition Based Service CBS
CBS is a further development of the Service
Interval Indicator System. Sensors and
sophisticated algorithms take even more
detailed account of the various conditions of
vehicle use.
The remaining times for selected mainte-
nance tasks as well as any legally prescribed
dates are displayed to you individually:
Engine oil
Brakes – front and rear separately
Microfilter
Brake fluid
Spark plugs
Vehicle check
Required State Inspection(s)
CBS thus determines the current and future
maintenance requirements. This data can
also be read from the vehicle key by your
BMW Service Advisor and used to propose
the optimum scope of maintenance.
Have maintenance and repair work
performed by your BMW center. Make sure
that the maintenance work is stamped in this
Service and Warranty Information Statement.
These entries are the evidence of regular
maintenance of your vehicle and a require-
ment for warranty claims.

Disconnecting the battery during
periods of long-term storage will inter-
rupt the calculation of time-based services.
Have all items requiring time-based mainte-
nance, such as brake fluid and possibly also
the engine oil and microfilter, brought up to
date by your BMW center. Also see the
section on battery care on page 16 of this
statement.
Service Interval Display
Info Display screen contents
The distance remaining until your next
service briefly appears when you switch on
the ignition.
The Info Display immediately switches
to its compute mode when you press
one of the two buttons in the turn signal
indicator lever.
Control Display screen contents
The current Status of Service items deter-
mined by the CBS are shown in the Control
Display.
You can view additional information on
service and maintenance procedures by
selecting the “OB data” menu.
1. Select and confirm
2. Select “Service” and confirm your entry
3. The display shows a list of selected
service and maintenance procedures, as well
as any required state inspections.
Red Sectors
The service deadline has already passed.
Yellow Sectors
The deadline for service or a state inspection
is approaching. Please contact your BMW
center for an appointment.

Maintenance summary
The Condition Based Service System (CBS)
will determine the requirement for perform-
ance of the maintenance services described
on this and the following page. These
services may be required either individually
or in conjunction with other maintenance
services.
Standard operations
Maintenance work
• Brief diagnostic test
• Verify Check Control messages
• Check indicator and warning lights
• Reset CBS display
Engine oil
Maintenance work
• Change the engine oil and oil filter. Werecommend BMW High Performance 5W-
30 Synthetic Oil P/N 07 51 0 017 866.
• After every 3rd engine oil change: Intake air cleaner: replace air filter element
(reduce replacement interval in dusty
operating conditions).
• Parking brake: check function
Microfilter
Maintenance work
• Replace ventilation microfilter
Front brake
Maintenance work
• Replace brake pads, clean brake pad contact points in calipers.
• Brake discs: Check surface and thickness, if necessary
replace at extra charge*
Rear brake
Maintenance work
• Replace brake pads, clean brake pad contact points in calipers.
• Brake discs: Check surface and thickness, if necessary
replace at extra charge*
• Parking brake: Check condition, brake lining thickness and
function, if necessary replace at extra charge*.
*Unless covered by Maintenance Program
Vehicle Check
Maintenance work
• Check operation of horn, headlight flasher and hazard warning flashers.
• Check instrument and control lighting and heater/air-conditioning blower.
• Check lighting system: turn signals, back- up, license plate, interior (incl. map, reading
lights), glovebox, flashlight, luggage area
lights.
• Safety belts: check condition and function.
• Check windshield wiper and washer jet positions.
• Body: check for corrosion (except cavities).
• Tires: check tread depth, wear pattern, outer condition, inflation pressure (also
spare tire).
If necessary, correct pressure (also spare).
• Battery: check state of charge (magic eye) and charge if required.
• Power steering reservoir: Check fluid level.
• Visually inspect all SRS airbag units for torn covers, obvious damage or attachment of
stickers.
• Rear-view mirrors
• Coolant: check fluid level and concentra- tion.
• Windshield washer and intensive cleaning system: check protection level, fluid level,
top if necessary.
