Flat Tire MonitorThe conceptThe Flat Tire Monitor keeps track of the
inflation pressures in your tires as you
drive. The system provides an alert
whenever the inflation pressure drops
significantly in one of the tires.
To initialize the Flat Tire Monitor system
with the correct tire inflation pressures,
start by checking the inflation pressures
in all four tires, comparing them with
the figures specified in the tire inflation
pressure table (page 23). Then correct
the tire inflation pressures as neces-
sary. Now you can activate the system. The Check Control (refer to page 66)
will inform you if the tire inflation pres-
sure of one the tires has dropped signif-
icantly.
Activating the system1. Turn the ignition key to position 2
(do not start the engine)
2. Press the button and maintain pres-
sure until the message "SET TIRE
PRESSURE" appears in the Check
Control (several seconds)
3. As you drive, the Flat Tire Monitor
automatically enters the system ini-
tialization mode in which it stores the
current pressures as its reference
figures. The initialization process
lasts for ten minutes or somewhat
longer. Once it has been completed
the Tire Pressure Monitor is able to
detect and warn of flat tires.39mde119
Repeat this process after altering the
tire inflation pressure, changing the tire,
or rotating the wheels.
Do not carry out a new initialization of
the system, if you correct the inflation
pressures to the already specified tire
pressures.

Washer fluids Engine oilHeadlamp and windshield
washer systemCapacity in US quarts (liters).
Windshield washer:
Approx. 3.7 US quarts (3.5 liters)
With headlamp-washing system:
Approx. 6.3 US quarts (6.0 liters).
Fill with water and Ð if required Ð with a
washer antifreeze (according to manu-
facturer's recommendations).
We recommend that you mix the
washer fluid before adding it to
the reservoir.< 39mde128
Intensive-cleaning washer
reservoirCapacity approx. 1.1 US quarts
(1.0 liter).
Fill with intensive-cleaning washer fluid.
It resists freezing down to approx. Ð 17
7 (Ð 27 6) and is available from your
BMW center.
Antifreeze agents or intensive-
action washer fluids for the
washer systems are highly inflammable.
For this reason, keep them away from
sources of flame and store them only in
their original containers. Store them so
that they are inaccessible to children.
Comply with the instructions on the
containers.<39mde129
Checking oil level 1. Park the vehicle on a level surface
2. Allow the engine to run at operating
temperature for at least 15 seconds
at idle, then shut it off
3. After approx. one minute, pull the
dipstick 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 level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions. 39mde042

Coolant Brake fluidChecking coolant level and
adding coolantCorrect coolant level when the engine
is cold (approx. 68 7/20 6):
In the translucent container's visible
range, as far as the graduation marked
KALT/COLD.
1. Turn the cap counterclockwise
slightly in order to allow accumulated
pressure to escape
2. If the coolant is low, slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of extended-duty antifreeze with
corrosion inhibitor.<39mde111
Brake fluid level
The warning lamp for the brake
system hydraulic circuits comes
on and/or the message "CHECK
BRAKE FLUID" appears in the
Check Control:
Brake fluid level too low.
To add brake fluidThe brake fluid reservoir is located
under the microfilter housing on the
driver's side of the vehicle. For adding
brake fluid or for determining and cor-
recting the cause of brake fluid loss,
consult your BMW center. Your BMW
center is familiar with the specifications
for factory-approved brake fluids
(DOT 4).
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the information on page 108.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years at
a BMW center. Refer also to the Service
and Warranty Information Booklet (US
models) or the Warranty and Service
Guide Booklet (Canadian models).
Brake fluid is hazardous to health and
damages the vehicle's paint. You
should always store it in its original
container and in a location which is out
of reach of children. Do not spill the
fluid and do not fill the brake fluid reser-
voir beyond the MAX mark. The brake
fluid could ignite upon contact with hot
engine parts and cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of brake fluid.<

OverviewControlsMaintenanceRepairsDataIndex
The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating safety Ð and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining its resale
value. 380us008
Service Interval DisplayConventional systems rely solely on
distance traveled to determine when
service is due. The BMW Maintenance
System, on the other hand, began many
years ago to take the actual conditions
under which the vehicle is driven into
consideration. After all, different drivers
can accumulate mileage in very dif-
ferent ways.
From a maintenance point of view,
62,000 miles (100,000 km) of short-dis-
tance driving cannot be compared with
62,000 miles (100,000 km) of long-dis-
tance highway travel.
In response to this fact, the BMW Main-
tenance System monitors operating
conditions as the basis for determining
the optimum service intervals for your
individual vehicle. The BMW Mainte-
nance System includes the Engine Oil
Service and Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those who
drive only short distances Ð significantly
less than 6,000 miles (10,000 km) annu-
ally Ð should have the engine oil
changed at least every 2 years since oil
deteriorates over time, regardless of
use.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet (US models) or the War-
ranty and Service Guide Booklet (Cana-
dian models).
As a precaution against corrosion, it is
advisable to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your vehicle's maintenance
and repairs performed at your
BMW center.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models) or the
Warranty and Service Guide Booklet
(Canadian models). These entries are
your proof that the vehicle has received
regular maintenance. They are also a
requirement for warranty claims.<

OBD interface socketThe Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD (Onboard-
Diagnostics) system is to assure proper
emission-control system operation for
the vehicle's lifetime by monitoring
emissions-related components and
systems to detect deterioration and
malfunction.390us739
An illuminated indicator 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 the
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.
Service Engine Soon warning
lamp for Canadian models.
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 indi-
cator should go out within a few days.<
