MaintenanceVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equipment
is also described that is not available in a vehicle,
e. g., because of the selected optional equip‐
ment or country variant. This also applies for
safety-related functions and systems.
BMW Maintenance System
The maintenance system directs you to re‐
quired maintenance measures and thereby sup‐
ports you in maintaining road safety and the op‐
erational 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.
Detailed information on service requirements,
refer to page 77, can be displayed on the Control
Display.
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 history
Perform maintenance work at the service center
and have them recorded in the vehicle data. The
entries are like a service booklet of the docu‐
mentation of regular maintenance.
Displaying entered maintenance work on the
Control Display, refer to page 78.
Service and Warranty
Information Booklet for US
models and Warranty and
Service Guide Booklet for
Canadian models
Please consult your Service and Warranty Infor‐
mation Booklet for US models and Warranty and
Service Guide Booklet for Canadian models for
additional information on service requirements.
Maintenance and repair should be performed by
your service center. Make sure to have regular
maintenance procedures recorded in the vehi‐
cle's Service and Warranty Information Booklet
for US models, and in the Warranty and Service
Guide Booklet for Canadian models. These en‐
tries are proof of regular maintenance.Seite 277MaintenanceMobility277

Socket for OBD Onboard
Diagnosis
Position
There is an OBD socket on the driver's side for
checking the primary components in the vehicle
emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as pos‐
sible.
Canadian model: warning light indi‐
cates the engine symbol.▷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.
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
BMW Assist, certain vehicle data can be sent
directly from the vehicle to facilitate the desired
services.Seite 278MobilityMaintenance278

Power failure
After a temporary power loss, some equipment
needs to be reinitialized.
Individual settings need to be reprogrammed:▷Seat and mirror memory: store the positions
again.▷Time: update.▷Date: update.▷Radio station: save again.▷Navigation system: wait for the operability of
the navigation.
Disposing of old batteries
Have old batteries disposed of by your
service center or bring them to a recy‐
cling center.
Maintain the battery in an upright position for
transport and storage. Secure the battery so
that it does not tip over during transport.
Fuses
Notes Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substitute
of another color or amperage rating; this could
lead to a circuit overload, ultimately resulting in
a fire in the vehicle.◀
