Start the hybrid system and turn the air conditioning system
on to check that the radiator cooling fans operate and to
check for coolant leaks from the radiator or hoses.
The fans operate when the air conditioning system is turned on
immediately after a cold start. Confirm that the fans are operating
by checking the fan sound and air flow. If it is difficult to check
these, turn the air conditioning system on and off repeatedly.
(The fans may not operate in freezing temperatures.)
