12 Volt auxiliary battery. Numerous safeguards have been designed into the AVALON Hybrid to help ensure the high voltage, approximately 244.8 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle (HV) battery pack is kept safe and secure in an accident.
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 AVALON Hybrid never needs to be recharged from an external electric power source.
AVALON Hybrid Identification In appearance, the 2013 model year AVALON Hybrid is nearly identical to the conventional, non-hybrid Toyota AVALON. The AVALON 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 and on the driver side B pillar.

Vehicle Operation With the AVALON 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 AVALON 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 area behind the rear seat.
Auxiliary Battery The AVALON Hybrid contains a sealed 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 negative terminal of 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 ...
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.
The AVALON 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.
Dismantling the vehicle The following 3 pages contain general instructions for use when working on an AVALON 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.
