A couple of cycles are triggered when you initially start a Gen 2 Prius 04-09 year. The vehicle will likely attempt to do these cycles.

Maintain 12 Volt Aux battery around 12 -13 volt battery and recharge during warm up

Run until a O2 sensor heater reaches a pre set temp .

Recharge traction battery if too low of SOC

If the above thresholds are not met... the vehicle is going to have OBD codes that should be checked

Current ambient temperature has effects additionally ....dead of winter like a Texas February longer vehicle warm up time... Peak of Texas summer 90F plus vehicle shut down fast for ICE.
