Inspection Mode

CAUTION: Driving the vehicle without deactivating inspection mode may damage the transaxle.
NOTE: When the A/C compressor operation is not required, the engine is warmed up, and the battery is charged properly, the PRIUS automatically stops the engine while the vehicle is at rest. In the case of a continuous engine operation is needed for performing engine maintenance, activate inspection mode. Inspection mode enables the engine to run continuously.
NOTE: The idling speed in inspection mode is approximately 1000 rpm. The engine speed increases to 1500 rpm if the accelerator pedal is depressed by less than 60%. If the accelerator pedal is depressed by more than 60 percent, the engine speed increases to 2500 rpm.
NOTE: If a DTC is set during inspection mode, the master warning lamp and the error warning lamp illuminate on the multi-information display. When the master warning lamp illuminates during inspection mode, deactivate inspection mode, and check for DTC(s).
