10. NOTE: When the engine is star ted from cold and run for a
short period only, before being swit ched off, a quantity of oil will
be 'hung up' within the engine because it is not up to operating
temperature.
Should the oil level subsequently be topped-up, the level could
become too high, causing oil burning.
Typically, 0.875 L is hung up.
Refill the engine with the correct specification engine oil.
11. Connect the battery and in stall the battery cover.
Refe
r to the Battery Reconnection Procedure 86.15.15.
12. Check the oil level and start th e engine. Check for leaks and
that the engine runs correctly.
13. Install the engine compartmen t cover. Refer to operation
76.16.01.
14. Remove the paintwork protection sheets and close the engine
