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 directs you to re‐
quired maintenance measures and thereby
supports you in maintaining road safety and
the operational 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.
Details on the service requirements, refer to
page 79, can be displayed on the Control Dis‐
play.
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.
Service booklet Perform maintenance work at the service cen‐
ter, and record the work in the service booklet.
The entries are proof of regular maintenance.

models and Warranty and
Service Guide Booklet for
Canadian models
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‐

Socket for OBD Onboard
Diagnosis
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.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that
fuel vapor is escaping. If the cap is then tight‐
ened, the display should go out in a short time.

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
Seite 204MobilityReplacing components204
Online Edition for Part no. 0140 2 910 771 - VI/13

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.
Xenon headlamps
Hints
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
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.◀
For checking and adjusting headlamp aim,
please contact your BMW center.Seite 205Replacing componentsMobility205

Vehicle batteryMaintenance
The battery is maintenance-free, i.e., the elec‐ trolyte will last for the life of the battery.
Your service center will be glad to advise you
on questions regarding the battery.
Battery replacement Use approved vehicle batteries only
Only use vehicle batteries that have been
approved for your vehicle by the manufacturer; otherwise, the vehicle could be damaged and
systems or functions may not be fully availa‐
ble.◀
After a battery replacement, have the battery registered on the vehicle by your service cen‐
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 212, 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:▷Seat, mirror, and steering wheel memory:
store the positions again.▷Time: update.▷Date: update.▷Radio station: saving new, see user's
manual for Navigation, Entertainment and
Communication.▷Navigation system: wait for the operability
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 Notes 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
