BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The service schedule also
includes operations related to the vehicle's
comfort and convenience features, such as
replacement of the filters for the inside air.
The ultimate objective is to ensure economical
maintenance by providing the ideal service for
your vehicle.
Should the day come when you decide to sell
your BMW, you will find that a complete dealer
service history is an asset of inestimable value.
CBS Condition Based Service
Sensors and special algorithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirements, the system builds
the basis for trouble-free driving.
You can set the Control Display to show
remaining distances and times of selected
maintenance intervals and legally mandated
deadlines, refer to page72:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally required tests depending on local
regulations
Service data in remote control
Your vehicle stores the information required for
maintenance continuously in the remote con-
trol during driving. After accessing the data
stored in the remote control, your BMW Service
Advisor can suggest precisely the right array of
service procedures for your own individual vehi-
cle. For this reason, when you take your vehicle
in for service, you should give the BMW Service
Advisor the remote control last used to drive it.
Make sure the date is set correctly, refer
to page79, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
instrument panel.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.<
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, then certain vehicle
data can be transmitted or recorded to enable
corresponding services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.

Replacing components
220 4.Correct tire inflation pressure to 29 psi/
200 kPa. With the ignition switched on:
>Increase inflation pressure: switch on
device, position I. To check currently set
inflation pressure, briefly switch off
device.
Do not allow compressor to run
longer than 10 minutes, otherwise
the device will overheat and may be dam-
aged.<
>Reduce inflation pressure: press
button8 or turn screw8 on pressure
gauge.
If the inflation pressure is not held, drive
the vehicle again, refer to Distributing
sealant. Then repeat steps 1 to 4 once.
Using the M Mobility System can be ineffective
with tire damage from a size of approx. 0.16 in/
4 mm. Please contact the nearest BMW center,
refer to page225, or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel if the tire can-
not be made ready for driving with the
M Mobility System.<
The tire inflation pressure must be at least
29 psi/200 kPa. Otherwise, do not con-
tinue driving.<
Continue driving
Do not exceed the permissible maximum
speed of 50 mph/80 km/h, otherwise
accidents can occur.<
Reinitialize the Flat Tire Monitor.
For details, refer to page86.
Have the defective tire and the sealant bottle of
the M Mobility System replaced as soon as
possible.<
Changing wheels*
Safety precautions in the event of a flat
tire or wheel change: park the vehicle as
far as possible from passing traffic and on solid
ground. Switch on the hazard warning flashers.
Apply the handbrake and shift into first gear or
reverse with the manual transmission, or move the selector lever into a drive position with the
sequential transmission.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle
* or portable hazard warning
lamp
* is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.

Jump starting
When your battery is discharged, you can use
two jumper cables to start your BMW with
power from the battery in a second vehicle. You
can also use the same method to help start
another vehicle. Use only jumper cables with
fully-insulated clamp handles.
To avoid the risk of potentially fatal injury,
always avoid all contact with electrical
components while the engine is running. Care-
fully adhere to the following sequence, both to
prevent damage to one or both vehicles, and to
guard against possible personal injuries.<
Preparing
1.Check whether the battery of the other
vehicle has a voltage of 12 Volts and
approximately the same capacitance in Ah.
