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.

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.

CoolantVehicle equipmentAll 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.
Hints Danger of burns from hot engine
Do not open the cooling system while
the engine is hot; otherwise, escaping coolant
may cause burns.◀
Suitable additives
Only use suitable additives; otherwise,
engine damage may occur. The additives are
harmful to your health.◀
Coolant consists of water and additives.
Not all commercially available additives are
suitable for the vehicle. Information about the
suitable additives are available from the service
center.
Coolant level
Checking1.Let the engine cool.2.The coolant level is correct if it lies be‐
tween the minimum and maximum marks.
The marks are on the side of the coolant
reservoir.SymbolMeaningMaximumMinimum
Filling
1.Let the engine cool.2.Turn the cap of the coolant reservoir
slightly counterclockwise to allow any ex‐
cess pressure to dissipate, and then open
it.3.If the coolant is low, slowly add coolant up
to the specified level; do not overfill.4.Turn the cap until there is an audible click.
The arrows on the coolant reservoir and
the cap must point towards one another.5.Have the cause of the coolant loss elimi‐
nated as soon as possible.

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.

Position
There is an OBD socket on the driver's side for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning lamp lights up:
Emissions are deteriorating. Have
the vehicle checked as soon as
possible.
Canadian model: warning light indi‐
cates the engine symbol.▷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 182MobilityMaintenance182

Onboard vehicle tool kit
The onboard vehicle tool kit is stored under
the cargo floor cover in the cargo area.
Wiper blade replacement
Note Do not fold down the wipers without
wiper blades
Do not fold down the wipers if wiper blades
have not been installed; this may damage the
windshield.◀

Lamp and bulb replacement
Hints
Lamps and bulbs Lamps 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 with
them or they are not described here.
You can obtain a selection of replacement
bulbs at the service center.

Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system,
you should always switch off the lights af‐
fected 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 headlamps
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 the 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)
Light-emitting diodes installed behind a cover
serve as the light source for controls, display
elements and other equipment.
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.◀Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When
driving with the light switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the headlamps 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.
Headlamp setting
The headlamp adjustments can be affected by
changing lamps and bulbs. Therefore after a
change, have the headlamp setting checked
and corrected by Service.
