Check my signature for the LTR service manual and it will tell you all about that FI light.

Flashing light while running is telling you its overheating. Leave only a half inch of coolant in the overflow tank and fill the radiator completely. If you fill the overflow tank to the full line it will push it out even if everything is fine.
