Refer to owner's manual or service literature for specifics like safety switches and disconnect mechanisms. You should wear heavy rubber class 00 rated gloves. These types of gloves can withstand up to 1000 volts. Ensure these gloves don't have cracks or pin holes that would allow voltage to pass through your skin. The high voltage hybrid battery can create a potential lethal shock and is therefore important to verify the presence of voltage in hybrid batteries.
