Safety Precaution

WARNING: This page is about a different variant/trim than selected.

This hybrid system uses a DC 270V voltage system. Be sure to follow safety instructions below. Failure to follow safety instructions may result in serious injury or electrocution.

WARNING: A caution label for high voltage is attached to the high voltage components. The color of the high voltage cables and connectors are orange. Do not touch any of these high voltage components, cables, and connectors without proper Personal Protection Equipment (PPE).

NOTE: High Voltage Component: 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:

For your safety when servicing the hybrid vehicle:
- Wear Personal Protection Equipment (Insulation Gloves and Safety Glasses).
- Do not carry any metallic object (watch, ring etc.) which can cause short circuit.
- Use insulated tools
Before wearing the protective gear, make sure that they are not torn or broken and free of moisture.

NOTE: Personal Protection Equipment: Insulating Gloves, Safety Glasses

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.

WARNING: Be sure to shut off the high voltage circuit shown in the procedures below before working on any high voltage system component (Refer to "HIGH VOLTAGE SHUTOFF PROCEDURE " for more detailed procedures).

Turn the ignition switch off and disconnect the auxiliary 12V battery negative (-) cable.
Remove the safety plug (Turning the ignition switch ON with the safety plug removed may damage the hybrid control system).
Wait for more than 5 minutes so that the capacitor in the high voltage system can be naturally discharged.
Remove the rear seat and partition tray trim (Refer to "REAR SEAT ).
Remove the high voltage front cover (A). Measure the voltage between the inverter positive and negative power cable terminals.

Below 30V: High voltage circuit properly shut

More than 30V: High voltage circuit faulty

CAUTION: Attach the 'High Voltage Caution Car Topper' to the vehicle roof to inform other people of danger of high voltage.

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.

Hybrid Vehicle Refrigerant Recovery/Charging Precautions

Since the electric compressor uses high-voltage, you should use POE oil which have high Volumetric Resistivity.
Do not use the same A/C recovery/charging station as conventional belt-driven compressors.

WARNING: If the POE oil of the system gets mixed with PAG oil, then dielectric breakdown due to decreased volumetric Resistivity can occur and inoperative A/C compressor may result, A/C compressor may not work.
