MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support in maintaining road safety and
the operational reliability of the vehicle.
Condition Based Service CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 65, can be displayed on the instrument
cluster.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used 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 service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/acti‐
vated-charcoal filter.
Service and Warranty

An OBD socket for testing components that are
critical to exhaust composition is located under
a cover on the driver's side.
Emissions
▷The warning lamp lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Display of the previously described mal‐
functions on Canadian models.
Fuel cap The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel vapor is
escaping. If the cap is then tightened, the display
should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further. In addition, if you
signed a service contract for Assist, certain ve‐
hicle data can be sent directly from the vehicle
to facilitate the desired services.Seite 169MaintenanceMobility169
