  91. On the touchscreen, touch Thermal > Coolant System > Coolant Air Purge, and then touch Run, and allow the routine to complete.
    Informational PurposesAn informational icon, calling your attention
    참고
    Wait until coolant pumps stop running (audible noise). Routine Passed will appear, but pumps will run for 10 minutes. If you start another routine during this time, it will fail. Make sure that the vehicle is not in "Drive". Routine is still running despite the completed message. Speeds can be monitored in Garage under PT Thermal tab. Idle speed = ~1500 RPM. Test will vary speeds from 3500-6500 RPM and actuate valves between SERIES and PARALLEL. Putting the vehicle into "Drive" will stop this routine. If speeds hover at 7000 RPM, this indicates the pumps are air locked. Perform a vacuum fill. Continue to add coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle.
  92. Inspect the coolant level and top off as necessary.
