MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and
systems.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support 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 78, 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 that you used 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.Seite 241MaintenanceMobility241

Socket for OBD Onboard
Diagnosis
Socket for Onboard Diagnosis
The socket for Onboard Diagnosis may
only be used by the service center, by work‐
shops that operate according to the specifica‐
tions of the vehicle manufacturer with appro‐
priately trained personnel, and by other
authorized persons. Otherwise, its use may
lead to vehicle malfunctions.◀
On the driver's side is an OBD socket for
checking the primary components in the vehi‐
cle emissions.
Emissions
▷The warning lamp lights up:
The emissions values are deterio‐
rating. 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.
Display of the previously described
malfunctions on Canadian models.
Fuel cap
The indicator lamp lights up.
If the fuel cap is not properly tight‐
ened, the OBD system may conclude that fuel
vapor is escaping. If the cap is then tightened,
the display should go out in a short time.Seite 242MobilityMaintenance242

Lamp and bulb replacement
General information Lamps and bulbs make an essential contribu‐
tion to vehicle safety.
The manufacturer of your vehicle recommends
that you entrust corresponding procedures to
your service center if you are unfamiliar with
them or they are not described here.
You can obtain a selection of replacement
bulbs at your 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 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.

cuits.◀
Starting aid terminals
Connecting order
Connect the jumper cables in the correct
order; otherwise, there is the danger of injury
from sparking.◀
The so-called starting aid terminal in the en‐
gine compartment acts as the battery's posi‐
tive terminal.
The body ground or a special nut acts as the
negative terminal.
Connecting jumper cables

minal.2.Attach one terminal clamp of the positive
jumper cable to the positive terminal of the
battery, or to the corresponding startingaid terminal of the vehicle providing assis‐
tance.3.Attach the other end of the cable to the
positive terminal of the battery, or to the
corresponding starting aid terminal of the
vehicle to be started.4.Attach one terminal clamp of the negative
jumper cable to the negative terminal of
the battery, or to the corresponding engine
or body ground of the vehicle providing as‐
sistance.5.Attach the other end of the cable to the
negative terminal of the battery, or to the
corresponding engine or body ground of
the vehicle to be started.
Starting the engine
Never use spray fluids to start the engine.
