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.

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 containers.<
Always observe all applicable rules
and regulations for environmental
protection when disposing of used anti-
freeze and anticorrosion agents.<
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:
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 82 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 vehi-
cle 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 accord-
ingly.<

Maintenance

Maintenance
The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined with optimized safety. The ser-
vice schedule also includes operations
related to the vehicle's comfort and conve-
nience features, such as replacement of
the filters for the inside air. The aim is to
optimize maintenance with regard to
reducing the cost of running the 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
Service Interval Display. Sensors combine
with highly-specialized algorithms to sup-
ply 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: separate for front and rear
>Microfilter/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 main-
tenance regimen that reflects your own
individual requirements, Condition Based
Service builds the basis for trouble-free
driving.
You can find more detailed information
on the Service Interval Display on page 81.
Service and Warranty Information
Booklet for US models and
Warranty and Service Guide Booklet
for Canadian models
Please consult your Service and Warranty
Information Booklet for US models and
Warranty and Service Guide Booklet for
Canadian models for additional information
on service 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 War-
ranty and Service Guide Booklet for Cana-
dian models. These entries verify that your
vehicle has received the specified regular
maintenance, and may also be required
when submitting warranty claims.<
