Question

the electric drive system of a hybrid vehicle contains high voltage that is dangerous to the human body. for example, many hybrids have an hv (high - voltage) battery output voltage of more than 200 vdc. the inverter then converts the dc voltage into around 500 vac or more! therefore you must refer to the manufacturer service information for detailed operation instructions and wear appropriate personal protective equipment when working on hybrid vehicles. basic precautions - always wear hv rated gloves when working around the hv battery. - always disable hv system and wait the required time for the capacitors to drain, before working around any hv cables. - always follow manufacture specific instructions for disabling hv system. - before checking fluids or changing oil on a hybrid, make sure the ready light on the instrument panel is off. if the ready light is on, the engine may start at anytime without notice. - place warning labels and signs around a hv vehicle that has been immobilized for service to warn others of the potential danger. what should you do prior to disabling the hv system? follow manufacturer safety and service procedures for disabling the hv system. ensure that the ready light is on. wear protective hv gloves.

Explanation:

The text mentions always following manufacturer - specific instructions for disabling the HV system. Wearing HV - rated gloves is a general precaution when working around the HV battery, not specifically prior to disabling the system. Also, the 'READY' light should be off before performing certain tasks like checking fluids or changing oil, not on before disabling the HV system.

Answer:

Follow manufacturer safety and service procedures for disabling the HV system.
