Plug-in hybrid system precautions Take care when handling the hybrid system, as it contains a high voltage system (about 650V at maximum) as well as parts that become extremely hot when the hybrid system is operating. Obey the caution labels attached to the vehicle. Traction battery (hybrid battery) Location Hybrid battery (traction battery) Location Battery (traction battery) Location System components The illustration is an example for explanation and may differ from the actual item. Caution label High voltage cables (orange) AC charging inlet Onboard traction battery charger Service plug Hybrid battery (traction battery) Electric motor (traction motor) Power control unit and DC/DC converter Air conditioning compressor Note: Running out of fuel When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the vehicle with at least enough gasoline to make the low fuel level warning light (Low fuel level warning light) go off. If there is only a small amount of fuel, the hybrid system may not be able to start. (The standard amount of fuel is about 2.1 gal. [8.0 L, 1.8 Imp.gal.], when the vehicle is on a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.) Electromagnetic waves High voltage parts and cables on the Plug-in Hybrid Electric Vehicles incorporate electromagnetic shielding, and therefore emit approximately the same amount of electromagnetic waves as conventional gasoline powered vehicles or home electronic appliances. Your vehicle may cause sound interference in some third party-produced radio parts. Effect of magnetic forces If objects that generate strong magnetic forces, such as large speakers, are placed inside the luggage compartment or installed nearby, the generated magnetic forces may negatively affect the hybrid system. Hybrid battery (traction battery) (lithium-ion battery) The hybrid battery (traction battery) has a limited service life. The hybrid battery (traction battery) capacity (the ability to hold a charge) reduces with time and use in the same way as other rechargeable batteries. The extent at which capacity reduces changes drastically depending on the environment (ambient temperature, etc.) and usage conditions, such as how the vehicle is driven and how the hybrid battery (traction battery) is charged. This is a natural characteristic of lithium-ion batteries, and is not a malfunction. Also, even though the EV driving range becomes shorter when the hybrid battery (traction battery) capacity reduces, vehicle performance does not significantly become worse. In order to reduce the possibility of the capacity reducing, follow the directions listed on Capacity reduction of the hybrid battery (traction battery), “Capacity reduction of the hybrid battery (traction battery)”. Starting the hybrid system in an extremely cold environment When the hybrid battery (traction battery) is extremely cold (below approximately -22°F [-30°C]) under the influence of the outside temperature, it may not be possible to start the hybrid system. In this case, try to start the hybrid system again after the temperature of the hybrid battery increases due to the outside temperature increase etc. Warning: High voltage precautions The vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and AC high voltage is very dangerous and can cause severe burns and electric shock that may result in death or serious injury. Never touch, disassemble, remove or replace the high voltage parts, cables or their connectors. The hybrid system will become hot after starting as the system uses high voltage. Be careful of both the high voltage and the high temperature, and always obey the caution labels attached to the vehicle. Never try to open the service plug access hole located in the luggage compartment. The service plug is used only when the vehicle is serviced and is subject to high voltage. Road accident cautionsRoad accident cautions Observe the following precautions to reduce the risk of death or serious injury: Stop the vehicle in a safe place to prevent subsequent accidents. While depressing the brake pedal, apply the parking brake and shift the shift position to P to stop the Plug-in hybrid system. Then, slowly release the brake pedal. Do not touch the high voltage parts, cables and connectors. If electric wires are exposed inside or outside your vehicle, an electric shock may occur. Never touch exposed electric wires. Do not touch the battery if liquid is leaking from or adhering to it. If electrolyte (carbonic-based organic electrolyte) from the hybrid battery (traction battery) comes into contact with the eyes or skin, it could cause blindness or skin wounds. In the unlikely event that it comes into contact with the eyes or skin, wash it off immediately with a large amount of water, and seek immediate medical attention. If electrolyte is leaking from the hybrid battery (traction battery), do not approach the vehicle. Even in the unlikely event that the hybrid battery (traction battery) is damaged, the internal construction of the battery will prevent a large amount of electrolyte from leaking out. However, any electrolyte that does leak out will give off a vapor. This vapor is an irritant to skin and eyes and could cause acute poisoning if inhaled. Do not bring burning or high-temperature items close to the electrolyte. The electrolyte may ignite and cause a fire. If a fire occurs in the Plug-in Hybrid Electric Vehicle, leave the vehicle as soon as possible. Never use a fire extinguisher that is not meant for electric fires. Using even a small amount of water may be dangerous. If your vehicle needs to be towed, do so with front wheels raised. If the wheels connected to the electric motor (traction motor) are on the ground when towing, the motor may continue to generate electricity. This may cause a fire. (If your vehicle needs to be towed) Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto the ground, the fuel system may have been damaged. Leave the vehicle as soon as possible. Hybrid battery (traction battery) Your vehicle contains a sealed lithium-ion battery. Never resell, hand over or modify the hybrid battery. To prevent accidents, hybrid batteries that have been removed from a disposed vehicle are collected through Toyota dealer. Do not dispose of the battery yourself. Unless the battery is properly collected, the following may occur, resulting in death or serious injury: The hybrid battery may be illegally disposed of or dumped, and it is hazardous to the environment or someone may touch a high voltage part, resulting in an electric shock. The hybrid battery is intended to be used exclusively with your Hybrid Electric Vehicle. If the hybrid battery is used outside of your vehicle or modified in any way, accidents such as electric shock, heat generation, smoke generation, an explosion and electrolyte leakage may occur. When reselling or handing over your vehicle, the possibility of an accident is extremely high because the person receiving the vehicle may not be aware of these dangers. If your vehicle is disposed of without the hybrid battery having been removed, there is a danger of serious electric shock if high voltage parts, cables and their connectors are touched. In the event that your vehicle must be disposed of, the hybrid battery must be disposed of by your Toyota dealer or a qualified service shop. If the hybrid battery is not disposed of properly, it may cause electric shock that can result in death or serious injury. Caution while driving If the vehicle under floor area receives strong shock or impact while driving, stop the vehicle in a safe area and check around the bottom of the vehicle. If there is damage to the hybrid battery (traction battery) or liquid leakage, it may lead to a vehicle fire, etc. Do not touch the vehicle and immediately contact your Toyota dealer. Even if no damage can be seen under the floor, the hybrid battery (traction battery) may be damaged. If the vehicle under floor area receives strong shock or impact, have the hybrid battery (traction battery) inspected by your Toyota dealer. Modifications Do not modify the vehicle to make the height lower. It is easier for the hybrid battery (traction battery) in the under floor area to come in contact with the ground when the vehicle is lowered. If the hybrid battery (traction battery) is damaged, a vehicle fire may occur which could lead to death or serious injury. Notice: Notice about fuel For Plug-in Hybrid Electric Vehicles, fuel may remain in the tank for a long time and undergo changes in quality depending on the how the vehicle is used. Refuel at least 5.3 gal. (20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel a total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-month period), as this may affect components of the fuel system or the gasoline engine. If the vehicle has not been refueled for a certain amount of time and it is possible that the quality of the fuel remaining in the tank has changed, “ No New Fuel has been Added Recently Please refuel” is displayed on the multi-information display when the power switch is turned to ON. If the message is displayed, refuel the vehicle immediately. Hybrid system Emergency shut off system Emergency shut off system When a certain level of impact is detected by the impact sensor, the emergency shut off system blocks off the high voltage current and stops the fuel pump to minimize the risk of electrocution and fuel leakage. If the emergency shut off system activates, your vehicle will not restart. To restart the hybrid system, contact your Toyota dealer.
