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, a complete dealer service history
will prove to be 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 page75:
>Engine oil
>Brake pads, front and rear separately
>Brake fluid>Vehicle check
>Legally mandated inspections 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. You should therefore hand over the remote
control you last used to drive to the BMW Ser-
vice Advisor when you take your vehicle in for
service.
Make sure the date is set correctly, refer
to page82, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<
Service and Warranty Information
Booklet for US models and
Warranty and Service Guide Booklet
for Canadian models
Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW Sports Activity Vehicle Center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance.<

Maintenance
246
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 to the left on the driver's
side, on the underside of the instrument panel
under a cover.
Exhaust-gas values
The warning lamp lights up.
The exhaust-gas values worsen.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction in Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case you should reduce your speed and
proceed to the nearest BMW Sports Activity
Vehicle Center. Heavy engine misfiring causes
serious damage to the emission-relevant com-
ponents, especially the catalytic converter,
within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system will assume that
fuel vapor escapes. Then a display lights up. If
the cap is then tightened, the display will 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, certain vehicle data can
be transmitted or recorded to enable corre-
sponding services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.

Replacing components
248 For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
For bulbs for which replacement is not
described and for checking and adjusting
headlamp aim, please contact your BMW
Sports Activity Vehicle Center.<
Light-emitting diodes LEDs
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Xenon bulbs
The service life of these bulbs is very long and
the probability of a failure is very low, provided
that they are not switched on and off an unusual
number of times. If one of these bulbs should
nevertheless fail, it is possible to continue driv-
ing with great caution using the fog lamps, pro-
vided traffic laws in your area do not prohibit
this.
Have work on the xenon light unit includ-
ing changing the bulb carried out only by
your BMW Sports Activity Vehicle Center or a
workshop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. Due to the high voltage present in the
system, there is a danger of fatal injuries when
work is carried out improperly.<
Halogen bulbs:
Parking and daytime running lamps
H8 bulb, 35 watts
The bulb is pressurized. Therefore, wear
safety glasses and protective gloves.
Otherwise there is a danger of injuries if the
bulb is accidentally damaged during replace-
ment.<
1.Turn the cover to the left and remove.
2.Turn the bulbs to the left, pull off the con-
nector and replace.
3.Install in the reverse order.
Turn signals, front
24-watt bulb, PSY24W
1.Unscrew bulb holder with bulb to the left,
refer to arrow, and replace.
2.Install in the reverse order.
Side marker lamps, rear
To replace, please go to a BMW Sports Activity
Vehicle Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.

3.Check and correct the tire inflation pressure
at the earliest opportunity.
Protect valve stems with valve screw
caps against dirt and contamination.
Dirt in valve stems is a frequent source of
gradual air loss.<
4.Initialize the Flat Tire Monitor, refer to
page92, or reset the Tire Pressure Monitor,
refer to page94.
5.Replace the damaged tire as soon as possi-
ble and have the new wheel/tire balanced.
Driving with compact wheel
Drive reservedly and do not exceed a speed of
50 mph/80 km/h.
The driving characteristics change, for example
reduced track stability on braking, extended
braking distance, and altered self-steering
characteristics in the limit range. In conjunction
with winter tires, these characteristics are more
pronounced.
Only one compact wheel may be
mounted. Restore the wheels and tires to
their original size as quickly as possible. Failure
to do so is a safety risk.<
Vehicle battery
Battery care
The battery is 100 % maintenance-free, i.e., the
electrolyte will last for the life of the battery
when the vehicle is operated in a temperate cli-
mate. Your BMW Sports Activity Vehicle Center
will be glad to advise in all matters concerning
the battery.
Charging battery
Only charge the battery in the vehicle via the
terminals in the engine compartment with the
engine switched off. Connections, refer to
Jump starting on page256.
Disposal
Have old batteries disposed of following
replacement at your BMW Sports Activity
Vehicle Center or bring them to a collection
point. Maintain the battery in an upright position
for transport and storage. Always restrain the
battery to prevent it from tipping over during
transport.<
Power failure
After a temporary power loss, the functioning of
some equipment may be limited and require
reinitialization. Individual settings are also lost
and must be updated:
>Seat, mirror and steering wheel memory
The positions must be stored again, refer to
page44.
>Time and Date
The values must be updated, refer to
pages81, 82.
>Radio
Stations must be stored again if necessary,
refer to page168.
>Navigation system
Wait until the system starts, refer to
page159.
Fuses
Never attempt to repair a blown fuse and
do not replace a defective fuse with a sub-
stitute of another color or amperage rating, as
this could lead to a circuit overload, ultimately
resulting in a fire in the vehicle.<
Spare fuses, a pair of plastic tweezers and infor-
mation on the fuse assignment are located near
the fuses in the cargo bay.
