Maintenance
The BMW maintenance
system
The BMW maintenance system supports
the preservation of the traffic and operating
safety of your BMW. The service schedule
also includes operations related to the
vehicle's comfort and convenience fea-
tures, such as replacement of the filters for
the inside air. The ultimate objective is to
ensure economical maintenance by provid-
ing the ideal service for your vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
Sensors and special algorithms take the
different driving conditions of your BMW
into account. Condition Based Service
uses this to determine the current and
future maintenance requirement. By letting
you define a service and maintenance reg-
imen that reflects your own individual
requirements, the system builds the basis
for trouble-free driving.
The service requirement display, refer to
page 65, individually displays the time or
distance remaining for selected mainte-
nance work and any legally required inter-
vals:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter>Brake fluid
>Spark plugs
>Vehicle check
>Legally required tests depending on
local regulations.
Your vehicle stores this information contin-
uously in the master key while the vehicle is
being driven. After accessing the data
stored in the master key, your BMW Ser-
vice Advisor can suggest precisely the right
array of service procedures for your own
individual vehicle. You should therefore
hand over to the BMW Service Advisor the
key you last used to drive when you take
your vehicle for service.
Make sure the date in the Control
Center is always set correctly, refer to
page 74, as otherwise the effectiveness of
CBS Condition Based Service is not
ensured.<
Service and Warranty Information
Booklet for US models and Warranty
and Service Guide Booklet for
Canadian models
Please consult your Service and Warranty
Information Booklet for US models and

Take the time to ensure that these service
procedures are confirmed by entries in
your vehicle's Service and Warranty Infor-
mation Booklet for US models and War-
ranty and Service Guide Booklet for Cana-
dian models. These entries verify that your
vehicle has received the specified regular
maintenance, and may also be required
when submitting warranty claims.<
