Safety Precaution: Notes

WARNING: Since hybrid vehicles contain a high voltage battery, if the high voltage system or vehicles are handled incorrectly, this might lead to a serious accidents like 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 .)
The responsible worker keeps the removed safety plug to prevent the plug from being connected by mistake.
Do not keep any metal objects (watch, ring etc.) while working on the high voltage system, which it can cause serious accidents like electric shock.
Before beginning work on the high voltage system, the worker should wear personal protective equipment to prevent safety accidents. (Refer to Personal Protective Equipment .)
Never allow workers who are not wear personal protective equipment to touch the high voltage system. High voltage components should be covered with an insulation sheet to prevent safety accidents.
Use insulation tools when working on the high voltage system.
Put the removed high voltage components on the insulation mat.

Information

All the high voltage wiring and connectors are orange.
A caution label for high voltage is attached to the high voltage components.
High voltage components: High Voltage Battery Pack Assembly, Power Relay Assembly (PRA), BMS ECU, Hybrid Power Control Unit (HPCU), Hybrid Drive Motor, HSG, Electric A/C Compressor, Low DC/DC Converter (LDC), Power Cable, Electric Compressor etc.

WARNING: Use Mega Ohm Tester when measuring insulation resistance of the high voltage system.
Specification: High Impendance Digital Volt/Ohm Meter (DVOM) "Category 3"
Leads and Meter rated to 1, 000 voltage.

CAUTION: Inform of danger of high voltage by putting the "high voltage caution" on the vehicle as image below.

WARNING: Be sure to follow instructions below when repairing the high voltage cable.

Check the voltage of the high voltage connector, terminal or busbar before repairing.
Below 30V: High voltage circuit properly shut

More than 30V: High voltage circuit faulty
Be careful not to short circuit between positive (+) and negative (-) terminals.
Insulate the high voltage connector or terminal with an insulation tape after disconnecting.
Tighten the high voltage terminal with the specified torque.

CAUTION: The high voltage battery must be always handled horizontally during repairing or storage. Otherwise, there may be decline in battery performance or its life may be shortened.

CAUTION: Exposing the high voltage battery to intense heat may cause deterioration.
Do not bake over 70°C (158°F)/30 min or 80°C (176°F)/20 min when painting.
