Foreword This guide was developed to educate and assist dismantlers in the safe handling of Toyota Camry gasoline-electric hybrid vehicles. Camry 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 Camry hybrid, as they may not be familiar to dismantlers.
The result of combining these two power sources is improved fuel economy and reduced emissions. The gasoline engine also powers an electric generator to recharge the battery pack; unlike a pure all electric vehicle, the Camry hybrid never needs to be recharged from an external electric power source.
Camry Hybrid Identification In appearance, the 2012 model year Camry hybrid is a 4-door sedan. Exterior, interior, and engine compartment illustrations are provided to assist in identification. The alphanumeric 17 character Vehicle Identification Number (VIN) is provided in the front windshield cowl, right side floor and on the left side B pillar.

Vehicle Operation • With the Camry hybrid, the gasoline engine may stop and start at any time while the READY indicator is on. • Never assume that the vehicle is shut off just because the engine is off. Always look for the READY indicator status.
Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery The Camry hybrid features a high voltage Hybrid Vehicle (HV) battery pack that contains sealed Nickel Metal Hydride (NiMH) battery modules. HV Battery Pack • The HV battery pack is enclosed in a metal case and is rigidly mounted to the trunk floor pan cross member behind the rear seat.
Auxiliary Battery • The Camry hybrid also contains a lead-acid 12 Volt battery. This 12 Volt auxiliary battery powers the vehicle electrical system similar to a conventional vehicle. As with other conventional vehicles, the auxiliary battery is grounded to the metal chassis of the vehicle.
High Voltage Safety The HV battery pack powers the high voltage electrical system with DC electricity. Positive and negative orange colored high voltage power cables are routed from the battery pack, under the vehicle floor pan, to the inverter/converter. The inverter/converter contains a circuit that boosts the HV battery voltage from 244.8 to 650 Volts DC.
High Voltage Safety (Continued) Service Plug Grip • The high-voltage circuit is cut by removing the service plug grip (see page 15). 12 Volt Volt DC Hybrid Vehicle Computer Auxiliary Battery Compressor Electric Inverter/ Generator Converter Electric Volt DC Motor 3-Phas HV Battery Assembly High Voltage Safety System –...
Precaution to be observed when dismantling the vehicle WARNING: ・ The high voltage system may remain powered for up to 10 minutes after the vehicle is shut off or disabled. To prevent serious injury or death from severe burns or electric shock, avoid touching, cutting, or opening any orange high voltage power cable or high voltage component.
Spills The Camry hybrid contains the same common automotive fluids used in other non-hybrid Toyota vehicles, with the exception of the NiMH electrolyte used in the HV battery pack. The NiMH battery electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. The electrolyte, however, is absorbed in the cell plates and will not normally spill or leak out even if a battery module is cracked.
Dismantling the vehicle The following 2 pages contain general instructions for use when working on a Camry hybrid. Read these instructions before proceeding to the HV battery removal instructions on page 18. WARNING: ・ The high voltage system may remain powered for up to 10 minutes after the vehicle is shut off or disabled.

Instead, wash the eye(s) with a dilute boric acid solution or a large amount of water and seek medical care. 11. With the exception of the HV battery, remove parts by following procedures which are similar to conventional Toyota vehicles. For the removal of the HV battery, refer to the following pages.
Removal of HV battery WARNING: ・ Be sure to wear insulated gloves when handling high-voltage parts. ・ Even if the vehicle is shut off and the relays are off, be sure to remove the service plug grip before performing any further work.
