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

MaintenanceVehicle 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

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 80, 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.

Please consult your Service and Warranty In‐
formation Booklet for US models and Warranty
and Service Guide Booklet for Canadian mod‐ els for additional information on service re‐
quirements.
Maintenance and repair should be performed
by your service center. Make sure to have reg‐
ular maintenance procedures recorded in the
vehicle's Service and Warranty Information
Booklet for US models, and in the Warranty
and Service Guide Booklet for Canadian mod‐
els. These entries are proof of regular mainte‐
nance.
Socket for OBD Onboard

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 withSeite 202MobilityMaintenance202

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 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 203MaintenanceMobility203

Onboard vehicle tool kit
The onboard vehicle tool kit is located on the
right side in the cargo area in a storage com‐
partment. Open the cover.
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.◀
Replacing the wiper blades
1.To change the wiper blades, fold up, refer
to page 68, the wiper arms.2.Fold up and hold the wiper arm firmly.3.Squeeze the retainer spring, arrow 1, and
fold up the wiper blade, arrow 2.4.Remove the wiper blade forward from the

Lamp and bulb replacement
Hints
Lamps and bulbs Lamps and bulbs make an essential contribu‐

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)
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.◀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.

Xenon headlamps
Xenon headlamps
Because of the long life of these bulbs, the
likelihood of failure is very low. Switching the
lamps on and off frequently shortens their life.
If a bulb fails, switch on the front fog lamps and
continue the trip with great care. Comply with
local regulations.
Do not perform work/bulb replacement
on xenon headlamps
Have any work on the xenon lighting system,
including bulb replacement, performed only by
