1-1. Hybrid system


n High voltage precautions

The vehicle has high voltage DC and AC systems as well as a 12-volt sys- tem. DC and AC high voltage is very dangerous and can cause severe burns and electric shock that may result in death or serious injury. l Never touch, disassemble, remove or replace the high voltage parts,

cables and their connectors.

l 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.

l 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.

n Road accident cautions

Observe the following precautions to reduce the risk of injury. l Pull your vehicle off the road, put the shift lever in P, apply the parking

brake, and turn the hybrid system off.

l Do not touch the high voltage parts, cables and connectors. l

If electric wires are exposed inside or outside your vehicle, an electric shock may occur. Never touch exposed electric wires. If a fluid leak occurs, do not touch it as it may be strong alkaline electrolyte from the hybrid battery (traction battery). If it comes into contact with your skin or eyes, wash it off immediately with a large amount of water or if pos- sible, boric acid solution. Seek immediate medical attention. If a fire occurs in the hybrid 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 the front wheels raised. If the wheels with the electric motor (traction motor) are on the ground when towing, the motor may continue to generate electricity. This may cause an electricity leakage leading to a fire. (→P. 342)




n Nickel-metal hydride battery

Your vehicle contains a sealed nickel-metal hydride battery. If disposed of improperly, it is hazardous to the environment and there is a risk of severe burns and electrical shock that may result in death or serious injury.

n If the system activates

l Carefully check to see if there are exposed high voltage parts or cables.

Never touch the parts or cables. (→P. 25)

l 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.

n Hybrid battery air vent

l Do not put foreign objects over the air vent. The hybrid battery (traction

battery) may overheat and be damaged.

d r i v n g


l Clean the air vent regularly to prevent the hybrid battery (traction battery)

from overheating.

l Do not wet the air vent. It may cause a short circuit and damage the hybrid

battery (traction battery).

l Do not load a large amount of water such as water cooler bottles into the vehicle. If water spills over the hybrid battery (traction battery), the battery may be damaged.


1-2. Key information Keys

The following keys are provided with the vehicle.

Using the mechanical key

Electronic keys • Operating the smart key

system (→P. 36)

• Operating

the wireless

remote control function (→P. 47)

Mechanical keys Key number plate

Take out the mechanical key.

After using the mechanical key, store it in the electronic key. Carry the mechanical key together with the electronic key. If the electronic key battery is depleted or the entry function does not operate properly, you will need the mechanical key. (→P. 382)

n When required to leave a key to the vehicle with a parking attendant

Lock the glove box as circumstances demand. Set the luggage security sys- tem. (→P. 54, 248) Remove the mechanical key for your own use and provide the attendant with the electronic key only.

n Key number plate

Keep the plate in a safe place such as your wallet, not in the vehicle. In the event that a key is lost, a new key can be made by your Toyota dealer using the key number plate. (→P. 381)

n To prevent key damage

l Do not subject the keys to strong shocks, expose them to high tempera-

tures by placing them in direct sunlight, or get them wet.


l Do not expose the keys to electromagnetic materials or attach any mate-

rial that blocks electromagnetic waves to the key surface.

l Do not disassemble the electronic key.
