Rules and regulations
California Proposition 65
Warning
California laws require us to issue the fol-
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.
Always protect your skin by washing
thoroughly with soap and water.<
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.<

Jump-starting
When your battery is discharged you can
use two jumper cables to start your vehicle
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. Carefully adhere to the following
sequence, both to prevent damage to one
or both vehicles, and to guard against pos-
sible 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. This information can be found on
the battery
2.Switch off the engine of the support
vehicle
3.Switch off any consumer units in both
vehicles.
There must not be any contact
between the bodies of the two vehi-
cles, as otherwise there is a danger of short
circuits.<
Connecting the jumper cables
To avoid personal injury from sparks,
always observe this sequence when
connecting jumper cables.<
On your BMW, the so-called starting-aid
terminal in the engine compartment serves
as the battery positive terminal, refer also
to Engine compartment overview on
page 178. The symbol + is embossed on
the cover.
1.Open the cover of the BMW starting-aid
terminal. To do so, pull the tab
2.Attach one end of the jumper cable
plus/+ to the positive terminal of the
battery or a starting-aid terminal of the
vehicle providing assistance
3.Attach the second end of the cable to
the positive terminal of the battery or to
a starting-aid terminal of the vehicle to
be started
Your BMW has a special nut as body
ground or negative pole.
4.Attach one end of the jumper cable
minus/Ð to the negative terminal of the
battery or to an engine or body ground
of the vehicle providing assistance
