General information The engine oil consumption is dependent on
the driving style and driving conditions.
The engine oil consumption can increase in
case of, for example:▷Sporty driving.▷Break-in the engine.▷Idling of the engine.▷Usage of non-approved engine oil grades.
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
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.

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.

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. Additional information is available from
the service center.
Condition Based Service
CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your 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.
Detailed information on service requirements,
refer to page 86, 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 needed,
changing the engine oil and the microfilter/
activated-charcoal filter.

Socket for OBD Onboard
Diagnosis
Note Socket for Onboard Diagnosis
The socket for onboard diagnostics may
only be used by the service center or a work‐
shop that operates in accordance with the
specifications of the vehicle manufacturer with
correspondingly trained personnel and other
authorized persons. Otherwise, use may result
in operating problems for the vehicle.◀
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 194MobilityMaintenance194

have not been installed; this may damage the
windshield.◀
Replacing the wiper blades1.Fold up and hold the wiper arm firmly.2.Squeeze the retainer spring, arrow 1, and
fold up the wiper blade, arrow 2.3.Remove the wiper blade forward from the
catch.4.Insert the new wiper blade in reverse order
of removal until it locks in place.5.Fold down the wipers.
Folding down wipers before opening the hood
Before opening the hood, ensure that the
wiper arms with the wiper blades are against
the windshield to prevent damage.◀
Lamp and bulb replacement
Hints
Lights and bulbs Lights and bulbs make an essential contribu‐
tion to vehicle safety.
The manufacturer of the vehicle recommends
that you entrust corresponding procedures to
the service center if you are unfamiliar those or

Danger of burns
Only change bulbs when they are cool;
otherwise, there is a danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always reel off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not perform work/bulb replacement
on xenon headlights
Have any work on the xenon lighting system,
including bulb replacement, performed only by
a service center. Due to the high voltage
present in the system, there is a danger of fatal
injuries if work is carried out improperly.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.
Use a clean tissue, cloth or something similar,
or hold the bulb by its base.◀
Light-emitting diodes (LEDs)
Some items of equipment use light-emitting
diodes installed behind a cover as a light
source.
These light-emitting diodes, which are related
to conventional lasers, are officially designated as Class 1 light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never
stare into the unfiltered light for several hours;
otherwise, irritation of the retina could result.◀Headlight glass
Condensation can form on the inside of the ex‐
ternal lights in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
light glass does not need to be changed.
If the headlights do not dim despite driving
with the light switched on, increasing humidity
forms, e. g. water droplets in the light, have the service center check this.
Headlight setting The headlight adjustments can be affected by
changing lights and bulbs. Have the head‐
lights' settings checked and corrected by serv‐
ice after a replacement.
