Engine oilChecking oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, 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.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter). Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.
Adding engine oilWhile you should wait until the level has
dropped to just above the lower mark
before adding oil, you should never
allow the oil level to fall below this
mark.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the automatic
transmission, the differential, and the
power steering system.<
Recommendation: have the oil changed
at your BMW center.

Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their original
container and in a location which is out
of reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this
reason, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot
engine parts. It could ignite and cause
serious burns.<
Checking coolant levelCorrect coolant level for cold engine
(approx. 68 7 or +20 6):
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
2. The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck, but no more than 0.8 in (2 cm)
above it Ð that is, up to the second
mark on the float (refer also to the
schematic diagram next to the filler
neck)
3. If necessary, add coolant. 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
disposal of extended-duty antifreeze
with corrosion inhibitor.<

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 the resale
value of the vehicle.
Service Interval DisplayWhile conventional systems rely on
distance traveled alone to determine
when service is due, the BMW Mainte-
nance System has for years considered
the actual conditions under which the
vehicle operates, because miles can be
traveled in many different ways:
From a maintenance point of view,
62,000 miles (100,000 km) of short-
distance urban driving cannot be
compared with 62,000 miles
(100,000km) of long-distance highway
travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual use of the
vehicle covers every kind of operating
situation. However, even those who
only drive a little bit Ð significantly fewer
than 6,200 miles (10,000 km) annually Ð
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use.
Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet (Cana-
dian models)For additional information on specified
maintenance intervals and procedures,
please refer to the Service and
Warranty Information Booklet (US
models), or the Warranty and Service
Guide Booklet (Canadian models).
As a precaution against rust, it is advis-
able to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW center perform
maintenance and repair.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models), or in
the Warranty and Service Guide
Booklet (Canadian models). These
entries are your verification of regular
maintenance on your vehicle and are
required for the performance of
warranty repairs.<

OverviewControlsMaintenanceRepairsDataIndex
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, on the underside of
the instrument panel and under a cover
panel. The cover has the letters OBD on
it.
This interface makes it possible to
access data on emissions-related
components using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the
vehicle. However, the systems should
be checked by your BMW center at the
earliest possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe
engine misfiring over even a short
period of time can seriously damage
emission control system components,
especially the catalytic converter.
Service Engine Soon warning
lamp for Canadian models.
If the fuel filler cap is not on tight
enough, the OBD system can
detect leaking vapor and the indicator
will light up. If the fuel filler cap is then
tightened, the indicator will usually go
out after a short period of time.<
