Maintenance
The BMW maintenance
system
The BMW maintenance system supports the
preservation of the traffic and operating safety
of your BMW.
Regular maintenance is not only required for
the safety of the vehicle, it also improves the
resale value.
Service Interval Display
The BMW maintenance system takes the driv-
ing conditions of the vehicle into account when
determining service intervals:
From the point of view of maintenance,
62,000 miles/100,000 km accumulated in
short-distance urban driving are not the equiva-
lent of the same distance covered at moderate
speeds in long-distance highway travel.
The BMW maintenance system is divided into
engine oil service as well as Inspections I and II.
Determining the maintenance intervals accord-
ing to the actual loads on the vehicle covers
every kind of operating situation. However,
even those who drive only short distances,
significantly less than 6,200 miles/10,000 km
annually, should have the engine oil changed at
least every 2 years since oil deteriorates over
time, regardless of use.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over the
course of time. To ensure that the brake system
continues to provide safe and reliable perfor-
mance, remember to have the brake fluid changed at least every two years by a BMW
Sports Activity Vehicle Center, also refer to the
Service and Warranty Information Booklet for
US models or the Warranty and Service Guide
Booklet for Canadian models.<
Service and Warranty Information
Booklet for US models/Warranty and
Service Guide Booklet for Canadian
models
For detailed information on required mainte-
nance items and the work involved, please refer
to the Service and Warranty Information Book-
let for US models or to the Warranty and Service
Guide Booklet for Canadian models.
Depending on operating conditions, it may be
advisable to have the body checked for damage
from rocks or gravel as a precaution against cor-
rosion.
BMW recommends that you have your
BMW Sports Activity Vehicle Center per-
form the maintenance and repair.
Check that the maintenance work is recorded in
the Service and Warranty Information Booklet
for US models or the Warranty and Service
Guide Booklet for Canadian models. These
entries will serve as proof that the vehicle has
received regular maintenance.<
OBD connector
The interface socket for the Onboard Diagnos-
tics is located on the left of the driver's side at

Maintenance
94 the bottom of the instrument cluster and under
a cover. The cover has the letters OBD on it.
The most important components for the com-
position of the emissions can be checked by a
device via this interface.
If the Service Engine Soon indicator
lamp lights up either continuously or
intermittently, this indicates a malfunc-
tion in the emissions-related electronic sys-
tems. Although the vehicle remains operational,
you should have the systems checked by your
BMW Sports Activity Vehicle Center at the ear-
liest possible opportunity.
The illuminated indicator informs you of the
need for service, not that you need to stop the
vehicle. However, the systems should be
checked by your BMW Sports Activity Vehicle
Center at the next opportunity.
If the indicator blinks or flashes, this indicates
a high level of engine misfire. Reduce speed
and contact the nearest BMW Sports Activity
Vehicle Center immediately. Severe engine
misfiring over even a short period of time can
seriously damage emission control system
components, especially the catalytic converter.
Display of the previously described
malfunction on Canadian models.
If the fuel filler cap is not on tight enough,
the OBD system can detect leaking vapor
and the indicator lamp will light up. If the fuel
filler cap is then tightened, the indicator lamp
will usually go out after a short period of time.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
