Fuel specifications
Do not use leaded gasoline, otherwise
permanent damage to the catalytic con-
verter 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 93
Always use this premium grade fuel to obtain
maximum fuel economy and performance.
The minimum approved fuel grade is AKI 91.
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.<

value indicates the current oil level in liters
above Minimum.
After starting the engine, the last determined
value is displayed.
The oil level must be between the two marks.
Manual transmission: the engine oil level
will be shown in the lower display.<
Exact measurement
The oil level is measured continuously while
driving or when stopped with the engine run-
ning.
The determination of a new value can take
30 minutes or longer.
If only dashes are shown in the display,
it was not possible to determine a new
value. This can, for example, be the case when
driving short distances or with a sporty driving
style.<
Fast measurement
In addition to the continuous measurement, you
can also quickly determine the current oil level,
e.g. after adding engine oil, however with a low
measuring accuracy.
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button on the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button on the turn signal lever
for at least 2 seconds.
The oil level is determined. A clock symbol
is displayed during the measurement.
5.After approx. 1 minute the current oil level is
displayed.
If not all measuring conditions are met,
e.g. with the engine cold, "-.-" is dis-
played. The requested measurement is carried
out as soon as possible.<
Possible displays
1Oil level OK
2Oil level at minimum:
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below
3Oil level too high
Have the vehicle checked immedi-
ately, otherwise engine damage may
result if too much oil has been added.<
4Oil level at maximum
5Fast measurement running: oil level is being
determined
6No value can be determined at this time
Adding engine oil
Do not add oil until a value slightly above the
minimum of 0.0 US quarts/liters is displayed by
the oil level measurement. In this area a mes-
sage is also shown on the Control Display.
Add oil within the next 125 miles/200 km,
otherwise the engine could be damaged.
Add a maximum of 1 US quart/1 liter of oil, oth-
erwise the engine may be damaged by adding
too much oil.
ba8_m5us.book Seite 205 Montag, 5. Februar 2007 12:03 12

Under the hood
206 Add at least 0.5 US quart/0.5 liter of oil, other-
wise the oil level check cannot reliably display
the current oil level.<
Please conduct a fast measurement after
adding engine oil to check the oil quantity
added and to update the display.<
Continuous exposure to used oil has
caused cancer in laboratory testing.
For this reason, any skin areas that come into
contact with oil should be thoroughly washed
with soap and water.
Keep oil, grease etc. out of reach of children and
observe the warnings on the containers to pre-
vent health risks.<
Oil change
Have oil changed only at your BMW center or
at a workshop that works according to BMW
repair procedures with correspondingly trained
personnel.
Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Do not use oil additives, as these may
result in engine damage.<
Your BMW center will be happy to answer
detailed questions on BMW High Perfor-
mance Synthetic Oil or approved synthetic
oils.<
You can also call BMW of North America at
1-800-831-1117 or visit the website at
www.bmwusa.com to obtain this information.
Viscosity grades
Viscosity is a measure of an oil's flow rating and
is specified in SAE grades.
Approved oils belong to the SAE grade
10W-60.<
Alternative oil grades
If BMW High Performance Synthetic Oil is
unavailable, you can add small quantities of
other synthetic oils between oil changes.
Only use oils with the following specifications:
>Viscosity
preferred: SAE 10W-60;
alternative: SAE 10W-40, SAE 5W-50 or
SAE 10W-50
>Specification
API SJ/CF, API SK/CF or higher
Low ambient temperatures
The oils used by BMW from the factory for your
vehicle model can be used at virtually all ambi-
ent temperatures. However, if the vehicle is
operated for a longer period at temperatures
below –47/–206, your BMW center will be
happy to recommend a suitable oil.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns.<
Coolant is comprised of water and coolant addi-
tive. Not all commercially available additives are
suitable for your BMW. Ask your BMW center
for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard; observe the instruc-
tions on the containers.<
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives.<
Checking coolant level
1.Allow the engine to cool.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.

Maintenance
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 page68:
>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
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 page75, otherwise the effectiveness
of CBS Condition Based Service is not
ensured.<

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 speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially 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
signed a contract of participation for BMW
Assist, certain vehicle data can be transmitted
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.

Do not remove the covers, and never
stare into the unfiltered light for several
hours, as irritation of the retina could result.<
Xenon lamps
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.
Have work on the xenon lighting system
performed only by your BMW 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.<

Replacing components
216 select a drive position with the selector level for
a sequential transmission.
Have all vehicle occupants get out of the vehicle
and ensure that they remain outside the imme-
diate area in a safe place, such as behind a
guardrail.
If a warning triangle
* or portable hazard warning
lamp
* is required, set it up on the roadside at an
appropriate distance from the rear of the vehi-
cle. Comply with all safety guidelines and regu-
lations.
Change the wheel only on a level, firm surface
which is not slippery. The vehicle or the jack
could slip to the side if you attempt to raise the
vehicle on a soft or slippery surface such as
snow, ice, tiles, etc.
Position the jack on a firm support surface.
Do not use a wooden block or similar object as a
support base for the jack, as this would prevent
it from extending to its full support height and
reduce its load-carrying capacity.
To avoid serious or fatal injury: never lie under
the vehicle, and never start the engine while it is
supported by the jack.<
What you will need
To avoid rattling noises later on, note the posi-
tions of the tools before removing them, then
return them to their initial positions after com-
pleting work.
