MaintenanceVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and

BMW maintenance system The maintenance system indicates required
maintenance measures, and thereby provides
support in maintaining road safety and the op‐
erational reliability of the vehicle.
In some cases scopes and intervals may vary
according to the country-specific version. Re‐
placement work, spare parts, fuels and lubri‐
cants and wear materials are calculated sepa‐
rately. Further information is available from a
dealer’s service center or another qualified
service center or repair shop.
Condition Based ServiceCBS
Sensors and special algorithms take into ac‐
count the driving conditions of the vehicle.
Based on this, Condition Based Service recog‐
nizes the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance corresponding to your
user profile.
Information on service requirements can be
displayed on the Control Display.Service data in the remote control
Information on the required maintenance is
continuously stored in the remote control. The dealer’s service center can read this data out
and suggest a maintenance scope for the vehi‐
cle.
Therefore, hand the service advisor the remote
control with which the vehicle was driven most
recently.
Storage periods Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a dealer's service center or
another qualified service center or repair shop
update the time-dependent maintenance pro‐
cedures, such as checking brake fluid and, if
necessary, changing the engine oil and the mi‐
crofilter/activated-charcoal filter.
