Condition Based Service does not con-
tinue counting down to the next service
during periods when the vehicle is stored with
the battery disconnected or the battery switch
in the OFF position.
It is therefore important, independent of the dis-
play, to change the brake fluid at least every
2years.
The same is true for other time-dependent
maintenance procedures.<

BMW Maintenance System
The BMW Maintenance System serves to
retain the operating and road safety of your
BMW. The service schedule also includes oper-
ations related to the vehicle's comfort and con-
venience features, such as replacement of the
filters for the inside air. The aim is to optimize
maintenance procedures with a view to reduc-
ing 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 inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent 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 requirements, the system forms
the basis for trouble-free driving.
On the Control Display, you can have the
remaining times and distances for selected
maintenance procedures and any legally man-
dated deadlines displayed, refer to page78:
>Engine oil
>Brakes, separate for front and rear
>Microfilter
>Brake fluid
>Spark plugs>Vehicle check
>Legally prescribed inspections depending
on national regulations
Service data in the remote control
Your vehicle continuously stores service-
requirement information in the remote control
while you are driving. After accessing the data
stored in the vehicle key, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. This is why it is important when you take
your vehicle in for service to give the BMW Ser-
vice Advisor the last remote control you used
for driving.
Storage periods with the battery discon-
nected are not taken into account by the
CBS maintenance system. If this occurs, have a
BMW center update the time-dependent main-
tenance procedures, such as checking brake
fluid and if necessary engine oil and the micro/
activated charcoal filter.<
