lowing warning: 
Engine exhaust and a wide variety of 
automobile components and parts, 
including components found in the interior 
furnishings in a vehicle, contain or emit 
chemicals known to the State of California 
to cause cancer and birth defects and 
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit 
chemicals known to the State of California 
to cause cancer and birth defects or other 
reproductive harm. 
Battery posts, terminals and related acces-
sories contain lead and lead compounds. 
Wash your hands after handling. 
Used engine oil contains chemicals that 
have caused cancer in laboratory animals.

OBD connector 
The Onboard Diagnostic OBD interface 
socket is located on the left of the driver's 
side under the instrument panel and under 
a cover. 
The cover has the letters OBD on it. 
The purpose of the OBD system is to 
ensure proper operation of the emission 
control system for the vehicle's lifetime.
The system monitors emissions-related 
components and systems for deterioration 
and malfunction. 
An illuminated indicator lamp 
informs you of the need for service, 
not of the need to stop the vehicle. 
However, the systems should be checked 
by your BMW center at the earliest possible 
opportunity. 
Indicator lamp for Canadian mod-
els. 
Under certain conditions, the indicator will 
blink or flash. This indicates a rather severe 
level of engine misfire. When this occurs, 
you should reduce speed and consult the 
nearest BMW center as soon as possible. 
Severe engine misfire over only a short 
period of time can seriously damage emis-
sions control components, especially the 
catalytic converter. 
When the
 
fuel filler cap is not properly 
tightened, the OBD system can 
detect the vapor leak and the indicator 
lamp will light up. If the filler cap is subse-
quently tightened, the indicator lamp 
should go out within a few days.
