Hood
Releasing
Pull the lever located under the left side of
the instrument panel.
Never attempt to perform any service
or repair operations on your vehicle
without the required, professional technical
training. When you are unfamiliar with the
service procedures and precautions,
always have any required work carried out
at your BMW center. Unprofessional
attempts at service and repair, and the
incorrect handling of parts and materials
that can occur during such attempts, con-
stitute a potential safety hazard, both for
the vehicle's occupants and for other road
users.<
Opening
Pull the release handle and open the hood.
Closing
Close the hood from a height of approx.
16 in (40 cm) with momentum. It must be
clearly heard to engage.
Observe the same precautions that
apply to all closing operations by
ensuring that the hood's travel range is
clear and unobstructed before allowing the
hood to fall into position.
If you see any signs that the hood is not
completely closed while driving your
vehicle, you should stop at once and close
it securely.<

Engine oil
Checking oil level
1.Park the vehicle on a level surface
2.Switch the engine off after it has
reached normal operating temperature
3.After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean lint-
free cloth, paper towel, or similar mate-
rial
4.Carefully push the dipstick all the way
into the guide tube and pull it out again
5.The oil should extend to between the
two marks on the dipstick.
As is the case with fuel economy, the rate
at which the engine uses oil is strongly
influenced by driving style and operating
conditions.

The oil quantity between the two marks on
the dipstick is approx. 1.1 US quarts
(1 liter). Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.
Adding engine oil
Wait until the level has dropped to just
above the lower mark before adding oil.
BMW engines are designed to ope-
rate without additives, and their use
could even lead to damage in some cases.
This also applies to the automatic transmis-
sion, the differential and the power steering
system.<
Recommendation: have your oil changed
only at your BMW center.
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.
Always store oil, grease, etc., well out of
the reach of children; always observe all
warning labels on the containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used oil.<
Specified engine oils
The quality of the engine oil selected has
critical significance for the operation and
service life of an engine. BMW approves
only specific oils after confirming their sui-
tability for use in its vehicles with extensive
testing.
Use only approved BMW High Perfor-
mance Synthetic Oil.If you are unable to obtain BMW High Per-
formance Synthetic Oil, you can add small
amounts of another synthetic oil between
oil changes. Use only oils with the API SH
specification or higher.
Ask your BMW center for details con-
cerning the specific BMW High Per-
formance Synthetic Oil or synthetic oils
which have been approved.<
You can also call BMW of North America at
1-800-831-1117 or visit this website:
www.bmwusa.com to obtain this informa-
tion.
Viscosity ratings
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in the
area where you typically drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Coolant
Do not add coolant to the cooling
system when the engine is hot.
Escaping coolant can cause burns.
Antifreeze and anticorrosion agents are
hazardous to health. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Antifreeze and anticorrosion agents are
flammable. Therefore, do not pour over hot
engine parts, as otherwise they could catch
fire and cause burns. Always observe the
instructions for use provided on the con-
tainer.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anti-corrosion agents.<

Under the hood
192
Checking coolant level
Correct coolant level with the engine cold
Ð approx. +687 (206):
1.Turn the cap of the expansion tank
counterclockwise to allow any accumu-
lated pressure to escape, then continue
turning to open
2.The coolant level is correct when the
coolant extends to between the MIN
and MAX marks on the filler neck, refer
to the diagram adjacent to the filler
neck
3.If the coolant is low, slowly add coolant
up to the specified level Ð do not overfill.
Brake fluid
The symbol lights up and a mes-
sage appears in the Check Control
panel:
The brake fluid in the reservoir has fallen to
below the minimum level.
The brake fluid reservoir is located under
the microfilter housing trim panel on the
driver's side of the vehicle. To have brake
fluid added to the system, or to have the
source of any brake fluid loss traced and
rectified, please contact your BMW center,
which can also supply the factory-
approved Ð DOT 4 Ð brake fluids.
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 performance,
remember to have the brake fluid changed
every two years at the latest, refer to
page 84 and to the Service and Warranty Information Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original containers
kept well away from the reach of children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. Should it come into contact with hot
engine components, the brake fluid could
ignite and cause personal injury in the form
of burns.<
Always observe all applicable envi-
ronmental rules and regulations when
disposing of used brake fluid.<
Warning lamp for Canadian models.
Brake hydraulic systems
A low brake-fluid level combined with
longer-than-usual pedal travel could be a
sign that one of the brake system's
hydraulic circuits has failed.
Proceed to the nearest BMW center.
Remember that pedal travel may be
increased, and there may also be a sub-
stantial increase in the amount of pedal
pressure required to brake the vehicle.
Please adapt your driving style accor-
dingly.<

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is desi-
gned to ensure that your vehicle will con-
tinue to furnish consistent reliability com-
bined with optimal safety. 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 object is to
furnish economical maintenance by provi-
ding the ideal service for your individual
vehicle.
Should the day come when you decide to
sell your BMW, you will find that a complete
dealer service history is an asset of inesti-
mable value.
CBS Condition Based Service
CBS is a more advanced version of the Ser-
vice Interval Display. Sensors combine with
highly-specialized algorithms to supply
service information that reflects your
vehicle's actual operating conditions more
precisely than ever before.
The system now furnishes individual dis-
plays of the times remaining until the dead-
lines for specific service operations as well
as official state inspections:
>Engine oil
>Brakes Ð separate for front and rear
>Particle/activated-charcoal filter
>Brake fluid >Spark plugs
>Vehicle check
>Coolant
>Official state inspections.
CBS monitors both current and upcoming
service requirements. After accessing the
data stored in the vehicle's key, your BMW
service advisor is able to suggest precisely
the right array of service procedures for
your own individual vehicle.
By letting you define a service and mainte-
nance regimen that reflects your own indi-
vidual requirements, Condition Based Ser-
vice builds the basis for trouble-free
driving.
You can find more detailed information on
the Service Interval Display on page 83.
Service and Warranty Information
Booklet for US models and Service
Guide Booklet for Canadian models
Please consult your Service and Warranty
Information Booklet for US models and
Service Guide Booklet for Canadian
models for additional information on ser-
vice requirements.
Have service and repair operations
performed at your BMW center.
Take the time to ensure that these service
procedures are confirmed by entries in
your vehicle's Service and Warranty Infor-
mation Booklet for US models and Service
Guide Booklet for Canadian models. These
entries verify that your vehicle has received
the specified regular maintenance, and
may also be required when submitting war-
ranty claims.<

Rules and regulations
California Proposition 65
Warning
California laws require us to state the fol-
lowing warning:
Engine exhaust, some of its constitu-
ents, and certain vehicle components
contain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of compo-
nent 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 tho-
roughly with soap and water.<
OBD connector
The Onboard Diagnostic Ð OBD Ð 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 emission-related components and systems for deterioration
and malfunction.
An illuminated 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.
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 will
light up. If the filler cap is subsequently
tightened, the indicator should go out
within a few days.<

Lamps and bulbs
The lamps and bulbs are essential factors
contributing to the safety of your vehicle.
Therefore, comply fully with the following
instructions during bulb replacement. If you
are not familiar with the specified proce-
dures, have the replacements carried out at
your BMW center.
Never touch the glass on new bulbs
with your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life.
Use a clean cloth, napkin, etc., or hold the
bulb by its metal socket.<
You can obtain a selection of replacement
bulbs at your BMW center. To prevent short circuits, before wor-
king on any electrical system, equip-
ment or accessory you should always
switch it off and disconnect the cable from
the battery's negative terminal before star-
ting.
To avoid possible injury or equipment
damage when changing bulbs, observe any
instructions provided by the bulb manufac-
turer.<

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. In the
unlikely event that one of these lamps
should fail, you can respond by switching
on your fog lamps and proceeding care-
fully, where allowed by law. To avoid risk of potentially fatal inju-
ries: owing to the extremely high vol-
tages at which these units operate, service
work should always be entrusted to quali-
fied personnel.<

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 vehicle. Comply with all
safety guidelines and regulations.
Change the wheel only on a level, firm sur-
face 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 sur-
face 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, note the positions
of the tools before removing them, then
return them to their initial positions after
completing work.
