Washer fluidHeadlamp* and windshield
washer systemApproximate capacity is
5.6 US quarts/5.3 liters.
Fill with water and, if required, with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in closed
original containers, inaccessible to chil-
dren. Comply with the instructions on
the containers.<
Engine oilChecking the 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 dip-
stick 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.

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.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their closed origi-
nal containers and in a location which is
out of reach of children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause serious burns. Comply with the
instructions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
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 rod – see
arrow – is at least even with the
upper edge of the filler neck, is at
least even with the upper edge of the
filler neck; see arrow. The end of the
float may stick out by a maximum of
3/4 in / 2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.

142Maintenance
The BMW Maintenance SystemThe BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively for
you as possible.
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.Service interval displayWhile 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 accumulated
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
includes the Engine Oil Service and
Inspections I and II.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals accord-
ing to individual operating conditions.
Minimal use drivers – those who drive
significantly fewer than
6,200 miles/10,000 km annually –
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 for US models/Warranty
and Service Guide Booklet for
Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els, or the Warranty and Service Guide
Booklet for Canadian models.As a precaution against corrosion, if
your vehicle is exposed to potential
damage from unimproved road sur-
faces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
Have your BMW center perform
maintenance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries confirm that your vehicle has
benefitted from regular maintenance,
and are also required for warranty
claims.<

143 Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust and a wide variety
of automobile components and
parts, including components found in
the interior furnishings in a vehicle, con-
tain or emit chemicals known to the
State of California to cause cancer and
birth defects and reproductive harm. In
addition, certain fluids contained in
vehicles and certain products of com-
ponent 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
accessories contain lead and lead com-
pounds. Wash your hands after hand-
ling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
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 let-
ters OBD on it.
This interface makes it possible to
access data on emissions-related com-
ponents using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
next 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
