Coolant
Coolant consists of half water and half 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. Because additives are harmful to your health, it is important
to follow the instructions on the containers.
Comply with the appropriate environmental protection
regulations when disposing of coolant additives.
If the coolant and therefore the engine overheats, a warning lamp lights up. A message appears on the Control Display.
Checking coolant level
Do not add coolant to the cooling system when
the engine is hot. Escaping coolant can cause burns.
1. Do not open the engine hood before the engine has cooled down.
2. Turn the cap of the expansion tank a little counterclockwise to allow any
accumulated pressure to escape, then continue turning to open.
3. The coolant level is correct if it is between the maximum and minimum marks
in the filler neck, refer also to the diagram next to the filler neck.

4. If the coolant is low, slowly add coolant up to the specified level;
do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss eliminated as soon as possible.
