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, inaccessible
to children. Comply with the instruc-
tions 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.

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.
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.<
Recommendation: have the oil changed
by your BMW center.
Specified engine oilsThe quality of the engine oil is
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.<
BMW engines are designed to
operate without oil additives; the
use of additives could even lead to
damage in some cases.<
Alternative oil typesIf a High Performance Synthetic Oil
approved by BMW should be unavail-
able, you may use small volumes of
other synthetic 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 open the cooling system
when the engine is hot. If you do,
escaping coolant can cause burns.<
Coolant consists of water and coolant
additives. Not all commercially available
additives are suitable for your BMW.
Your BMW center knows which addi-
tives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to health.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of coolant additives.<
Checking the coolant level1. The engine must be at ambient tem-
perature
2. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
3. The coolant level is correct when the
upper end of the red float is even
with the upper edge of the filler neck,
refer to the arrow in the illustration or
to the schematic diagram next to the
filler neck
4. If necessary, slowly add coolant until
the correct level is reached; do not
overfill
5. Close the cap by turning until it is
well tight
6. Have the cause for the coolant loss
removed as soon as possible.
