Foreword
This guide was developed to educate and assist dismantlers in the safe handling of Toyota
HIGHLANDER Hybrid gasoline-electric hybrid vehicles. HIGHLANDER Hybrid dismantling
procedures are similar to other non-hybrid Toyota 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 Toyota HIGHLANDER Hybrid, as they may not be familiar to
dismantlers.
High voltage electricity powers the electric motors, generator, air conditioning (A/C) compressor
and inverter/converter. All other automotive electrical devices such as the headlights, radio and
gauges are powered from a separate 12 Volts auxiliary battery. Numerous safeguards have been
designed into the HIGHLANDER Hybrid to help ensure the high voltage, approximately 288 Volts,
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:
•
Toyota HIGHLANDER Hybrid identification.
•
Major hybrid component locations and descriptions.
By following the information in this guide, dismantlers will be able to handle HIGHLANDER
Hybrid hybrid-electric vehicles as safely as the dismantling of a conventional non-hybrid
automobile.
