Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.

Coolant is composed of equal parts water and a
coolant additive. Not all commercially available
additives are suitable for your BMW. Ask your
BMW center for suitable additives.
Only use suitable additives, otherwise
engine damage may result. The additives
present a health hazard.
<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.
