This is a free PDF Dismantling Manual of the 2013 Lexus GS450h Hybrid. Please note that this is NOT the “Factory Service and Repair Manual” of the Lexus GS450h Hybrid.

What is the “Dismantling Manual”?

This guide was developed to educate and assist dismantlers in the safe handling of Lexus GS450h gasoline-electric hybrid vehicles. Lexus GS450h dismantling procedures are similar to other non-hybrid Lexus vehicles with the exception of the high voltage electrical system. It is important to recognize and understand the high voltage electrical system features and specifications of the Lexus GS450h, as they may not be familiar to dismantlers.

High voltage electricity powers the A/C compressor, electric motor, generator, and inverter/converter. All other conventional automotive electrical devices such as the headlights, radio, and gauges are powered from a separate 12 Volt auxiliary battery. Numerous safeguards have been designed into the GS450h to help ensure the high voltage, approximately 288 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle (HV) battery pack is kept safe and secure in an accident.

The NiMH HV battery pack contains sealed batteries that are similar to rechargeable batteries used in some battery-operated power tools and other consumer products. The electrolyte is absorbed in the cell plates and will not normally leak out even if the battery is cracked. In the unlikely event, the electrolyte does leak, it can be easily neutralized with a dilute boric acid solution or vinegar.
High voltage cables, identifiable by orange insulation and connectors, are isolated from the metal chassis of the vehicle. Additional topics contained in the guide include:

Lexus GS450h identification.
Major hybrid component locations and descriptions.

By following the information in this guide, dismantlers will be able to handle GS450h hybrid-electric vehicles as safely as the dismantling of a conventional gasoline engine automobile.
