The BMW Maintenance
System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes
operations related to the vehicle's comfort
and convenience features, such as
replacement of the filters for the inside air.
The aim is to optimize maintenance with
regard to reducing the cost of running the
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. As a result, Condition Based
Service determines the current and future
maintenance requirements. By letting you
define a service and maintenance regimen
that reflects your own individual require-
ments, the system forms the basis for trou-
ble-free driving.
The service requirement display, refer to
page82, shows you the times or distances
remaining until the deadlines for selected
service and maintenance procedures, as
well as legally-mandated inspections:
>Engine oil
>Brakes, separate for front and rear
>Microfilter/activated-charcoal filter >Brake fluid
>Spark plugs
>Vehicle check
>Coolant
>Legally prescribed inspections depend-
ing on national regulations.
Your vehicle stores this information contin-
uously in the ignition key while the vehicle
is being driven. After accessing the data
stored in the vehicle key, your BMW service
advisor is able to suggest precisely the
right array of service procedures for your
own individual vehicle. You should there-
fore hand over to the BMW service advisor
the key you last used to drive when you
take your vehicle for service.
Storage periods with the battery dis-
connected are not taken into account
by the CBS maintenance system. Have the
time-dependent service and maintenance
operations, such as brake fluid and cool-
ant, and if necessary engine oil and the
micro/activated charcoal filter, updated by
a BMW center.<
