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 Display

While conventional systems rely on
milage alone to determine when service
is due, the BMW Maintenance System
reflects the actual conditions under
which the vehicle is operated: some
miles are more strenuous than others.
From a maintenance point of view,
62,000 miles (100,000 km) accumu-
lated in short-distance urban driving are
not the equivalent of the same distance
covered at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System moni-
tors actual operating conditions as the
basis for defining when the Engine Oil
Service and Inspections I and II are
due.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals
according individual operating condi-
tions. However, drivers who cover only
extremely short distances Ð substan-
tially less than 6,200 miles (10,000 km)
annually Ð should still have the engine
oil changed at least every 2 years, as it
continues to age regardless of whether
the vehicle is used on a regular basis.

Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian 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 corrosion, if
your vehicle is exposed to potential
damage from unimproved road
surfaces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
We recommend that you refer all
maintenance and repair opera-
tions to your BMW center.
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 confirm that your vehicle has
benefitted from regular maintenance,
and are also required for warranty
claims.

OverviewControlsMaintenanceRepairsDataIndex
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument 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.

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.<
