Inspection Mode: Notes
NOTE:
- The PRIUS automatically stops the engine while the vehicle is stopped with the engine warmed up and battery well charged if the A/C compressor operation is not required. Therefore, even if the vehicle stops for any reason such as a check of ignition timing, the inspection mode should be activated when continuous operation of the engine is required.
- The PRIUS has a skid control as traction control function. When the wheel speed of the front wheels exceeds that of the rear wheels, this function restrains the wheel speed of the front wheels. It is necessary to activate the inspection mode and reset the skid control when turning only the front wheels using a speedometer tester.
