Overview
Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.
<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing. Any skin areas that come in
contact with oil should thus be thor-
oughly washed with soap and water.
Store oil, grease, etc., out of reach of
children. Comply with warning labels
and information on containers.
If you use SAE 15W-40 engine oil in low
temperatures (below +14
7
/–10
6
),
the engine may become difficult to
start.
Special engine oils individually
approved by BMW are preferred for use
in your engine. Please contact your
BMW center for details.
<
Do not add coolant to the cooling
system when the engine is hot. If
you do, escaping coolant can cause
burns.
To avoid the possibility of damage later
on, do not use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor which can be used
with aluminum radiator cores. Your
BMW center is familiar with the
approved specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. Store them in
their original containers. Keep the
containers tightly closed and out of
reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this
reason, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot
engine components. If you do, it could
be ignited and cause burns.
<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.
<
Checking coolant level
Correct coolant level when the engine
is cold (approx. +68
7
/+20
6
):
Unscrew the cap from the expansion
tank.
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 illustra-
tion), but no more than 0.8 in (2 cm)
above it – that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).
