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.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor. Your BMW Sports
Activity Vehicle center is familiar with
the factory specifications.
Antifreeze and anticorrosion agents are
hazardous to health. You should always
store them in their original container
and in a location which is inaccessible
to children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol. For this
reason, do not spill antifreeze with
corrosion inhibitor on hot engine parts.
It could ignite and cause serious
burns.<
Checking coolant level and
adding coolant Correct coolant level when the engine
is cold approx. +68 7(+20 6):
1. Start by turning the cap of the expan-
sion tank counterclockwise. Pause to
allow any accumulated pressure to
escape, then open
2. 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
cap)530us102
3. If necessary, add coolant. Slowly add
coolant until the correct level is
reached Ð do not overfill.
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
