Before filling, turn on ignition. Set blower to low level. Seat heating
controller to maximum temperature. This ensures that the heater
valves are fully opened and the auxiliary water pump starts up.

to ensure fully venting!

Start engine and run at idle speed for approx. two minutes (cap
open). Then adjust coolant level to MAX.

thermostat opens. Check cooling circuit and drain plug for leaks.
