Engine oil Coolant Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.
Do not open the cooling system
when the engine is hot. Escaping
coolant can cause burns.<
Coolant is comprised of water and
coolant additive. Not all commercially
available additives are suitable for your
BMW. Your BMW Sports Activity Vehi-
cle center knows which additives are
suitable.
Use only suitable additives, other-
wise you could damage your
engine. The additives can be harmful
to your health.<
Always observe all applicable
environmental rules and regula-
tions when disposing of coolant addi-
tives.<
Checking coolant level 1. The engine must be at ambient tem-
perature
2. Start by turning the cap of the expan-
sion tank counterclockwise. Pause to
allow any accumulated pressure to
escape, then open
3. The coolant level is correct when the
end of the red float is aligned with
the upper edge of the filler opening,
refer to the arrow in the illustration,
or max. 0.8 in/2 cm higher, i. e. up to
the mark on the float, refer also to the
schematic diagram, next to the cap530us102
