Ask your BMW center for details
concerning the specific BMW
High Performance Synthetic Oil or syn-
thetic oils that have been approved.<
You can also call BMW of North Amer-
ica toll-free at 1-800-831-1117 or visit
this website: www.bmwusa.com to
obtain this information.
Viscosity ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These kinds of oil may be used for driv-
ing in all ambient temperatures.
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 original con-
tainers 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 burns. Comply with the instruc-
tions on the containers.<
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; 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.
