Engine oilVehicle equipment
All standard, country-specific and optional
equipment that is offered in the model series is
described in this chapter. Therefore, equip‐
ment is also described that is not available in a
vehicle, e. g., because of the selected optional
equipment or country variant. This also applies
for safety-related functions and systems.
General information The engine oil consumption is dependent on
the driving style and driving conditions. When
a sporty driving style is used, the engine oil
consumption, for example, is clearly higher.
Therefore, regularly check the engine oil level
after refueling.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles.▷Status display▷Detailed measurement
Checking the oil level
electronically
Status display
The concept The oil level is monitored electronically during
driving and shown on the Control Display.
If the oil level reaches the minimum level, a
check control message is displayed.
Requirements A current measured value is available after ap‐
prox. 30 minutes of driving. During a shorter
trip, the status of the last, sufficiently long trip
is displayed.
With frequent short-distance trips, regularly perform a detailed measurement.
Displaying the oil level1."Vehicle Info"2."Vehicle status"3. "Engine oil level"
Oil level display messages
Different messages appear on the display de‐
pending on the oil level. Pay attention to these
messages.
If the engine oil level is too low, within the next
125 miles/200 km Add oil, refer to page 201.
Engine oil level too low
Add oil immediately; otherwise, an insuf‐
ficient amount of engine oil could result in en‐
gine damage.◀
Take care not to add too much engine oil. Too much engine oil
Have the vehicle checked immediately;
otherwise, surplus oil can lead to engine dam‐
age.◀
Detailed measurement
The concept
In the detailed measurement the oil level is
checked and displayed via a scale.
During the measurement, the idle speed is in‐
creased somewhat.
General information
A detailed measurement is only possible with
certain engines.

When too much engine oil is added, im‐
mediately have the vehicle checked, otherwise,
this may cause engine damage.◀
Protect children
Keep oil, grease, etc., out of reach of chil‐
dren and heed the warnings on the containers
to prevent health risks.◀
Oil types for refilling
Hints No oil additives
Oil additives may lead to engine dam‐
age.◀
Viscosity grades for engine oils
When selecting an engine oil, ensure that
the engine oil belongs to one of the viscosity
grades SAE 0W-40, SAE 0W-30, SAE 5W-40,
and SAE 5W-30 or malfunctions or engine
damage may occur.◀
The engine oil quality is critical for the life of
the engine.

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.
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 82, can be displayed on the Con‐
trol Display.
Service data in the remote control Information on the required maintenance is
continuously stored in the remote control. Your service center will read out this data and
suggest the right array of service procedures
for your vehicle.
Therefore, hand your service specialist the re‐
mote 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 service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/
activated-charcoal filter.

ter to ensure that all comfort functions are fully
available and that any Check Control mes‐
sages of these comfort functions are no longer
displayed.
Charging the battery
Note Do not plug chargers into the socket
Do not connect battery chargers to the
factory-installed sockets in the vehicle as this
may damage the battery.◀
General information Make sure that the battery is always suffi‐
ciently charged to guarantee that the battery
remains usable for its full service life.
The battery may need to be charged in the fol‐
lowing cases:▷When making frequent short-distance
drives.▷If the vehicle is not used for prolonged pe‐
riods, longer than a month.
Starting aid terminals
In the vehicle, only charge the battery via the
starting aid terminals, refer to page 219, in the
engine compartment with the engine off.
Power failure After a temporary power loss, some equipment
needs to be reinitialized.
Individual settings need to be reprogrammed:

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 Hints Replacing fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a substi‐
tute of another color or amperage rating; this
could lead to a circuit overload, ultimately re‐
sulting in a fire in the vehicle.◀
Plastic tweezers and information on the fuse
types and locations are stored in the fuse box
