Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, drive off at a moderate engine speed.
The engine starts when you depress the
brake pedal while briefly pressing the
Start/Stop button.<
Procedure
1.Depress brake pedal.
2.Briefly press the Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
Special starting conditions
Depress the accelerator pedal half way when
starting the engine in the following situations:
>The engine fails to start on the first attempt,
e.g. if it is very hot or cold.
>The engine is started at very low tempera-
tures, below approx. + 57/– 156, at high
altitudes, over approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned or inadequately burned and
there is a danger of overheating and damaging
the catalytic converter.<
Switching off engine
When leaving the vehicle, always take the
remote control with you.
When parking on a downhill incline, set the
parking brake, otherwise the vehicle could roll
away.<
Procedure
1.Engage transmission position P with the
vehicle stopped.
2.Briefly press the Start/Stop button.
Procedure before driving into a car
wash
The vehicle can roll if you proceed according to
the following steps:
1.With comfort access
*: insert the remote
control into the ignition lock.
2.Depress brake pedal.
3.With the engine running, engage transmis-
sion position N.
4.Release the parking brake.
5.Switch off the engine.
6.Leave the remote control in the ignition
lock.
Transmission position P will be engaged:
>automatically after approx. 30 minutes
>if you remove the remote control from the
ignition lock
Parking brake
The concept
Your BMW is equipped with an electromechan-
ical parking brake that is set and released with a
button.
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked.
With the engine stopped, the parking brake acts
on the rear wheels via an electromechanical
system. When the engine is running, the park-
ing brake acts on the disc brakes of the front
and rear wheels via the brake hydraulics.

Fuel specifications
Do not use leaded gasoline, otherwise
damage to the catalytic converter will
result.
Do not use E85, i.e. fuel that consists of 85 %
ethanol, or Flex Fuel, otherwise permanent
damage to the engine and the fuel supply sys-
tem will result.<
Required fuel
Super Premium Gasoline/AKI 91
This gasoline is highly recommended.
However, you may also use gasoline with less
AKI. The minimum AKI Rating is 87.
If you use gasoline with this minimum AKI Rat-
ing, the engine may produce knocking sounds
when starting at high outside temperatures.
This has no affect on the engine life.
Do not use gasoline below the specified
minimum quality, otherwise engine dam-
age can result.<
Use high-quality brands
Field experience has indicated significant dif-
ferences in fuel quality: volatility, composition,
additives, etc., among gasolines offered for sale
in the United States and Canada. Fuels contain-
ing up to and including 10 % ethanol or other
oxygenates with up to 2.8 % oxygen by weight,
that is, 15 % MTBE or 3 % methanol plus an
equivalent amount of co-solvent, will not void
the applicable warranties with respect to
defects in materials or workmanship.
The use of poor-quality fuels may result in
drivability, starting and stalling problems
especially under certain environmental condi-
tions such as high ambient temperature and
high altitude.
Should you encounter drivability problems
which you suspect could be related to the fuel
you are using, we recommend that you respond
by switching to a recognized high-quality brand
such as gasoline that is advertised as Top Tier
Detergent Gasoline.Failure to comply with these recommendations
may also result in unscheduled maintenance.<

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.
The warning lamp lights up if the fuel
filler cap is not properly tightened and
the OBD system can close when fuel
vapor escapes. If the fuel filler cap is then tight-
ened, the display must 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
signed a contract of participation for
BMW Assist, certain vehicle data can be trans-
mitted or recorded to enable corresponding
services.
Care
Important information on the care and mainte-
nance of your BMW is contained in the Caring
for your vehicle brochure.
