Coolant
M roadster, M coupe
M roadster, M coupe:
The correct coolant level when the
engine is cold (approx. 68 7/20 6):
Up to the KALT/COLD mark (arrow) of
the transparent expansion tank.
To add coolant
Wait until the engine cools before re-
moving the cap from the expansion
tank. The needle of the coolant gauge
in the instrument cluster must be lo-
cated in the blue field; otherwise, there
is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached – do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the pre-
scribed all-season 50 :50 mixture ratio
for year-round protection against inter-
nal corrosion. No other additives are re-
quired.
Replace the coolant regularly. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide (Canadian models).
