speeds during acceleration requires more fre-
quent 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 Condition
Based Service (CBS) system which computes
the actual optimum maintenance 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.
Condition Based Service (CBS)
CBS is a further development of the Service
Interval Indicator System. Sensors and sophisti-
cated algorithms take even more detailed
account of the various conditions of vehicle use.
The remaining times for selected maintenance
tasks as well as any legally prescribed dates are
displayed to you individually:
Engine oil
Brakes - front and rear separately
Brake fluid
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 Ser-
vice Advisor and used to propose the optimum
scope of maintenance.
Disconnecting the battery during periods
of long-term storage will interrupt the
calculation of time-based services. Have all
items requiring time-based maintenance, 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 17 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.
For certain maintenance operations, you can
view the respective distance remaining or due
date individually in the instrument cluster.
1. Push button 1 in the turn indicator lever up
or down repeatedly until the appropriate
symbol appears in the display, accompanied
by the words “SERVICE-INFO”.
2. Press button 2.
3. Use button 1 to scroll through the individual service items.
