Safety Precaution: Notes

Precautions to take before servicing high voltage system

WARNING: Hybrid vehicles have high voltage batteries. Incorrect handling of high voltage system or vehicle may lead to serious accident including electric shock and electric leakage.

WARNING:

Be sure to shut off the high voltage by removing the safety plug before performing inspection or repairing the high voltage system.
(Refer to " HIGH VOLTAGE SHUT-OFF PROCEDURES ")
Keep the safety plug completely removed to prevent the plug from being connected by mistake.
Do not wear metallic objects (watch, ring etc.) while working on the high voltage system, due to risk of serious accidents like electric shock.
Whenever working on the high voltage system, wear personal protective equipment to prevent accidents. (Refer to "Personal Protective Equipment" below)
Technicians not wearing personal protective equipment must not be allowed to work on high voltage systems. Cover high voltage components with an insulated sheet to prevent accidents.
Use insulation tools when working on the high voltage system.
Put the removed high voltage components on the insulation mat.
