Because hybrid vehicles contain a high-voltage battery, improper handling of the high-voltage system or vehicle may result in serious accidents such as electric shock and current leakage.
All high voltage wiring and connectors are orange.
A high voltage warning label is attached to high voltage components.
High voltage components: High voltage battery pack, Power Relay Assembly (PRA), BMS ECU, Hybrid Power Control Unit (HPCU), Hybrid Traction Motor, HSG, electric A/C compressor, Low voltage DC-DC Converter (LDC), power cable, electric compressor, etc.
Indicate the high voltage hazard by attaching a "High Voltage Warning" to the vehicle, as shown in the figure below.

Description
Insulated Gloves
Used when inspecting or working on high voltage components [Insulation performance: 1000 V / 300 A or higher]
Insulated Shoes
Used when inspecting or working on high voltage components
Insulated Clothing
Insulated Helmet
Safety Glasses
Used in the following cases • Sparks may occur during removal, installation or inspection of high voltage battery terminals or wiring. • When working on the high voltage battery pack.
Face Shield
Insulated Mat
Place removed high voltage components on an insulated mat to prevent accidents.
Insulating Sheet
Cover high voltage components with an insulating sheet to prevent people who do not wear personal protective equipment from causing accidents.
The high voltage battery must always be handled in a horizontal position during repair or storage. Otherwise, battery charge performance or service life may be reduced.
Exposure of the high voltage battery to strong heat may cause deterioration. Do not bake at temperatures above 70 °C for 30 min or 80 °C for 20 min during painting.
