Washer fluidsHeadlamp* and windshield
washer systemCapacity approx.
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 their
closed original containers. Store them
inaccessible to children. 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. 1 minute, 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.
1.4 US quarts/1.3 liters.

123
Adding engine oilOnly add engine oil when the oil level
has dropped to just above the lower
mark on the dipstick.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
Before checking the engine oil level
after topping up, restart the engine and
allow it to run to obtain a correct dis-
play. Then proceed as described under
Checking the oil level.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This also applies to the
manual transmission, the differential,
and the power steering system.<
Recommendation: have the oil changed
at your BMW center.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, thoroughly
wash any areas of skin that come into
contact with oil using soap and water.
Store oils, grease and similar materials
so that they are inaccessible to chil-
dren. Comply with warning labels and
information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil. extremely important for the function
and life of an engine. Based on exten-
sive testing, BMW has approved only
certain grades of engine oil.
Use only oils approved for your vehicle
model.
Ask your BMW center for details
concerning oils that have been
approved. You can also call BMW of
North America toll-free at 1-800-831-
1117 or visit this website:
www.bmwusa.com to obtain this infor-
mation.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other oils for topping up between oil
changes. The following data must
appear on the packaging:
>Viscosity
preferred: SAE 10W-60
alternative: SAE 5W-40 or
SAE 10W-40
>Specifications
preferred: API SJ/CF
alternative: API SJ – also SK, SL, S
etc.Low ambient temperaturesThe oils used by BMW at the factory for
your vehicle model can be used at virtu-
ally any ambient temperature.

However, if the vehicle is exposed to
temperatures below –47/–206 for
extended periods, please have your
BMW center recommend a suitable oil.
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 inac-
cessible to children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause burns. Comply with the instruc-
tions on the containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
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 is at least
even with the upper edge of the filler
neck – refer to the arrow in the illus-
tration. The end of the float may stick
out by a maximum of 3/4 in / 2 cm –
that is, up to the second mark on the
float. Refer also to the schematic dia-
gram next to the filler neck

126Maintenance
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 the resale
value of the vehicle.Service interval displayWhile conventional systems rely on dis-
tance traveled alone to determine when
service is due, the BMW Maintenance
System has for years taken the actual
conditions under which the vehicle
operates into consideration, because
miles can be traveled in many different
ways:
For example, 62,000 miles/100,000 km
short-distance driving are not equal to
the same 62,000 miles/100,000 km of
long-distance travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Have a break-in inspection per-
formed at approx. 1,250 miles/
2,000 km regardless of the service
interval indicated on the display.<
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. Minimaluse-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 regardless of what
the service interval display indicates,
since oil deteriorates over time, irre-
spective 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, it is
advisable 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
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries are your verification for the reg-
ular maintenance of your vehicle and
are required for the performance of
warranty repairs.<

128Laws 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
handling.
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 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 system is to
assure proper emission-control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
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
earliest possible opportunity.

Jump-startingWhen your battery is discharged, you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
The auxiliary jump-starting terminal
located in your BMW's engine compart-
ment acts as the positive battery termi-
nal. Refer to the engine compartment
overview on page 120. The cover of this
auxiliary terminal is marked with a +.

positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be started
4. Your BMW is equipped with a special
nut – see arrow 2 – to serve as the
ground or negative terminal.
Attach a terminal clamp of the
minus/– jumper cable to the negative
terminal of the support vehicle's bat-
tery or to a suitable ground on its
engine or bodywork
