Coolant
Do not open the cooling system
when the engine is hot. If you do,
escaping coolant can cause burns.
<
Coolant consists of water and coolant
additives. Not all commercially available
additives are suitable for your BMW.
Your BMW center knows which addi-
tives are appropriate.
Only use approved additives, as
the engine could otherwise be
damaged. The additives are hazardous
to health.
<
Comply with the applicable envi-
ronmental laws regulating
the disposal of coolant additives.

Checking the coolant level
1. The engine must be at ambient tem-
perature
2. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape. Then open
3. The coolant level is correct when the
upper end of the red float is even
with the upper edge of the filler neck,
refer to the arrow in the illustration or
to the schematic diagram next to the
filler neck
4. If necessary, slowly add coolant until
the correct level is reached; do not
overfill
5. Close the cap by turning until it is
well tight
6. Have the cause for the coolant loss
removed as soon as possible.
