2004 BMW 525I SEDAN check oil

Technology for comfort, convenience and safety
80 tance during panic stops. This system
exploits all of the benefits provided by ABS.
Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released,
DBC is deactivated.
In the event of a malfunction, the
warning lamp in the instrument
cluster lights up yellow.
Have the system checked and repaired at
your BMW center as soon as possible.
Please note any information that appears
on the Control Display.

Active roll stabilization*
The concept
Active roll stabilization minimizes body roll
and optimizes vehicle stability during cor-
nering and evasive maneuvers.
Dynamic stabilizers at the front and rear
axles form the basis for active roll stabiliza-
tion. Suspension compliance adapts to suit
driving conditions, varying from perfor-
mance-oriented during cornering to
smooth and comfort-oriented when the
vehicle is proceeding in a straight line.
The system assumes operational status
each time you start the engine.
Driving with active roll stabilization
During vehicle operation, the system con-
tinuously runs through closed-loop control
cycles lasting only fractions of a second.
In case of malfunction
The symbol in the instrument clus-
ter lights up and a message
appears on the Control Display.
Please note any supplementary information
that appears there.
You can find more information on the
Check Control starting on page 68. If the active roll stabilization system is
deactivated in response to malfunc-
tion, please remember to adapt your speed
accordingly, especially in curves.
The suspension will be noticeably softer
and the vehicle will display a greater ten-
dency to tilt during cornering and in cross-
winds.
If a message stating that you should stop
appears on the Control Display in addition
to the red symbol, stop immediately and
switch off the engine. In this case the oil
level in the reservoir may have dropped
below the minimum, possibly owing to a
leak in the hydraulic system.
Please note any supplementary information
that appears on the Control Display.<
Flat Tire Monitor
The concept
The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires as
you drive. The system provides an alert
whenever the inflation pressure drops sig-
nificantly in relation to the pressure in
another tire.
The check of the tire inflation pressure is
based on monitoring the relative speeds of
the wheels. A flat tire is detected and
reported on the basis of a deviation in cer-
tain speed ratios.
Functional requirement
So that the Flat Tire Monitor can learn the
correct inflation pressure, please perform
the following:
1.Check the inflation pressures in all tires
2.Compare with the inflation pressure
table on page 170 and correct if neces-
sary
3.Initialize the system.
Limits of the system
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused
by outside factors and does not detect a

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 4 out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material 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. 1.6 US quarts/
1.5 liters. Do not fill beyond the upper mark
on the dipstick. Excess oil can damage the
engine.

The BMW Maintenance
System
The BMW Maintenance System is
designed to ensure that your vehicle will
continue to furnish consistent reliability
combined 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 objective is
to ensure economical maintenance by pro-
viding 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
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 vehi-
cle's actual operating conditions more pre-
cisely than ever before.
The system now provides individual dis-
plays of the times or distances remaining
until the deadlines for specific service
operations as well as legally prescribed
inspections:
>Engine oil
>Brakes: separate for front and rear
>Brake fluid
>Spark plugs >Vehicle check
>Depending on national regulations:
legally prescribed inspections.
CBS monitors both current and upcoming
service requirements. Your vehicle stores
this information continuously in the ignition
key while the vehicle is being driven. You
should therefore hand over to the BMW
Service Advisor the key you last used to
drive when you take your vehicle for ser-
vice. After accessing the data stored in the
vehicle 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 requirement display on
page 66.
Make sure the date in the Control
Center is always set correctly, refer to
page 75, as otherwise the effectiveness of
Condition Based Service CBS is not
ensured. Booklet for US models and Warranty
and Service Guide Booklet for Cana-
dian 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

Rules and regulations
California Proposition 65
Warning
California laws require us to issue the fol-
lowing warning:
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the interior
furnishings in a vehicle, contain or emit
chemicals known to the State of California
to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component 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
thoroughly with soap and water.<
OBD connector
The Onboard Diagnostic OBD 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 emissions-related
components and systems for deterioration
and malfunction.
An illuminated indicator 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.
Indicator lamp for Canadian mod-
els.
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
lamp will light up. If the filler cap is subse-
quently tightened, the indicator lamp
should go out within a few days.<
