1. Read the coolant level. The coolant level must be
between the min and max markings.
2. If the coolant level is below the min mark, add
coolant.
3. Carefully screw off the coolant reservoir cap and
allow any excess pressure to escape.
4. Unscrew the cap completely.
5. Top up coolant. Only use a mixture consisting of
equal parts of freeze protection agent and dis-
tilled water. Do not fill beyond the max mark.
6. Screw on the cap of the coolant reservoir until
you feel it engage.
7. Significant coolant loss indicates leaks the cool-
ant system. Check the cooling system and have
the cause of the coolant leak rectified
immediately. Visit an authorized Porsche dealer.
Porsche recommends an authorized Porsche

nificant coolant loss indicates leaks the coolant
system.
