the engine at operating temperature

dipstick 3 out and wipe it off with a
clean lint-free cloth, paper towel, or
similar material3.Carefully push the dipstick all the way
into the guide tube and pull it out again
4.The oil should extend to between the
two marks on the dipstick.
The engine oil consumption is dependent
on driving style and driving conditions.
The oil quantity between the centers of the
two marks on the dipstick, refer to arrows,
is approx. 1.6 US quarts/1.5 liters. Do not
fill beyond the upper mark on the dipstick.

Brake system
Malfunction
Brake fluid
The warning lamp lights up in red
in spite of the handbrake being
released; a message appears on
the Control Display.
Stop the vehicle immediately.
The brake fluid in the reservoir has fallen to
below the minimum level. At the same time,
a significantly longer brake pedal path is
noticeable. Have the system checked
immediately by a BMW center.
Warning lamp for Canadian models.
When you continue driving, an
increased brake pedal path can be
necessary, and significantly longer braking
distances might be required. Please adapt
your driving style accordingly.<
Brake pads
The warning lamp lights up in red
in spite of the handbrake being
released; a message appears on
the Control Display. The brake pads have
reached their minimum pad thickness.
Have the brake pads replaced as soon as
possible.
Warning lamp for Canadian models.For your own safety: use only brake
pads that BMW has approved for your
particular vehicle model. As BMW cannot
assess the suitability of other brake pads
for use on your vehicle, BMW is unable to
assume continued responsibility for the
vehicle's operating safety if non-approved
pads are installed.<

Maintenance

Maintenance
The 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 fea-
tures, such as replacement of the filters for
the inside air. The ultimate objective is to
ensure economical maintenance by provid-
ing the ideal service for your 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
Sensors and special algorithms take the
different driving conditions of your BMW
into account. Condition Based Service
uses this to determine the current and
future maintenance requirement. By letting
you define a service and maintenance reg-
imen that reflects your own individual
requirements, the system builds the basis
for trouble-free driving.
The service requirement display, refer to
page 65, individually displays the time or
distance remaining for selected mainte-
nance work and any legally required inter-
vals:
>Engine oil
>Brakes, front and rear separately
>Microfilter/activated-charcoal filter>Brake fluid
>Spark plugs
>Vehicle check
>Legally required tests depending on
local regulations.
Your vehicle stores this information contin-
uously in the master key while the vehicle is
being driven. After accessing the data
stored in the master key, your BMW Ser-
vice Advisor can suggest precisely the right
array of service procedures for your own
individual vehicle. You should therefore
hand over to the BMW Service Advisor the
key you last used to drive when you take
your vehicle for service.
Make sure the date in the Control
Center is always set correctly, refer to
page 74, as otherwise the effectiveness of
CBS Condition Based Service is not
ensured.<
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.<
