Safety Precautions

WARNING: The vehicle has a hybrid system that operates at voltages up to 650V. The hybrid system uses an HV battery that contains an electrolyte which is a strong alkali solution that includes potassium hydroxide. Be sure to follow the instructions in this manual to handle the system correctly. Failure to do so may result in serious injury or electrocution.

Technicians must undergo special training to be able to service and inspect the high-voltage system.
All high-voltage wire harnesses and connectors are colored orange. The HV battery and other high-voltage components have "High Voltage" caution labels. Do not carelessly touch these wires or components.
When there is a problem with the wire harness or connector of a high-voltage circuit, repairs to the harness or connector should not be attempted. Replace damaged or malfunctioning high voltage cables or connectors.

CAUTION: After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.

Before inspecting or servicing the high-voltage system, be sure to follow all safety measures, such as wearing insulated gloves and removing the service plug to prevent electrocution. Carry the removed service plug in your pocket to prevent other technicians from accidentally reconnecting it while you are servicing the vehicle.

NOTE: Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

After removing the service plug, wait 10 minutes before touching any of the high-voltage connectors and terminals.
Before using insulated gloves, be sure to check them for cracks, tears and other types of damage.
When servicing the vehicle, do not carry metal objects like mechanical pencils or rulers that can be dropped accidentally and cause a short circuit.
Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0V.
After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately using insulating tape.
Bolts and nuts for high-voltage terminals should be tightened firmly to the specified torque. Both insufficient and excessive torque can cause failure.
Use the "CAUTION: HIGH VOLTAGE DO NOT TOUCH" sign to notify other technicians that the high-voltage system is being inspected and/or repaired.
After servicing the high-voltage system and before reinstalling the service plug, check again that you have not left a part or tool inside, that the high-voltage terminals are firmly tightened, and that the connectors are correctly connected.
When installing hybrid system components such as the HV battery, make sure that the polarity of all connections is correct.
