Engine oilVehicle 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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
General information The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
the following situations, for example:▷Sporty driving style.▷Break-in of the engine.▷Idling of the engine.▷With use of engine oil types that are classi‐
fied as not suitable.
Therefore, regularly check the engine oil level
after refueling.
When a dynamic driving style is used, such as
when cornering fast, the system is unable to
measure the engine oil level. With this driving
style, measure the engine oil level using a de‐
tailed measurement, refer to page 180.
The vehicle is equipped with electronic oil
measurement.
The electronic oil measurement has two meas‐
uring principles:
▷Status display.▷Detailed measurement.Electronic oil measurement
Status display
The concept
The engine oil level is monitored electronically
while driving and shown on the Control Dis‐
play.
If the engine 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 engine oil level
About iDrive:1."Vehicle info"2."Vehicle status"3. "Engine oil level"
The engine oil level is displayed.
Engine oil level display messages
Different messages appear on the display de‐
pending on the engine oil level. Pay attention
to these messages.
If the engine oil level is too low within the next
125 miles/200 km, add engine oil.
ATTENTION
Too low of an engine oil level causes en‐
gine damage. There is a risk of damage to
property. Immediately add engine oil.◀
Take care not to add too much engine oil.

ATTENTION
Too much engine oil can damage the en‐
gine or the catalytic converter. There is a risk
of damage to property. Do not add too much
engine oil. When too much engine oil is added,
have oil level corrected by a dealer’s service
center or another qualified service center or re‐
pair shop.◀
Detailed measurement
The concept In the detailed measurement the engine oil
level is checked when the vehicle is stationary,
and displayed via a scale.
If the engine oil level reaches the minimum
level, a check control message is displayed.
During the measurement, the idle speed is in‐
creased somewhat.
Requirements▷Vehicle is parked in a horizontal position.▷Manual transmission: shift lever in neutral
position, clutch and accelerator pedals not
depressed.▷M Double clutch transmission: selector
lever in selector lever position N and accel‐
erator pedal not depressed.▷Engine is running and is at operating tem‐
perature.
Performing a detailed measurement
In order to perform a detailed measurement of
the engine oil level:
1."Vehicle info"2."Vehicle status"3. "Measure engine oil level"4."Start measurement"
The engine oil level is checked and displayed
via a scale.
Time: approx. 1 minute.

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
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
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.

Socket for OBD Onboard
Diagnosis
Information ATTENTION
The socket for Onboard Diagnosis is an
intricate component intended to be used in
conjunction with specialized equipment to
check the vehicle’s primary emissions system.
Improper use of the socket for Onboard Diag‐
nosis, or contact with the socket for Onboard
Diagnosis for other than its intended purpose,
can cause vehicle malfunctions and creates
risks of personal and property damage. Given
the foregoing, the manufacture of your vehicle
strongly recommends that access to the
socket for Onboard Diagnosis be limited to a

Position
There is an OBD socket on the driver's side for
checking the primary components in the vehi‐
cle's emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.▷The warning lamp flashes under certain
circumstances:
This indicates that there is excessive mis‐
firing in the engine.
Reduce the vehicle speed and have the
system checked immediately; otherwise,
serious engine misfiring within a brief pe‐
riod can seriously damage emission con‐
trol components, in particular the catalytic
converter.Seite 185MaintenanceMobility185
