1-1. Hybrid system

Hybrid system

Your vehicle is a hybrid vehicle. It has characteristics different from

conventional vehicles. Be sure you are closely familiar with the char-

acteristics of your vehicle, and operate with care.

The hybrid system combines a gasoline engine and an electric

motor (traction motor) according to driving conditions, improving

fuel efficiency and reducing exhaust emissions.

Gasoline engine

Electric motor (Traction motor)

1-1. Hybrid system

 When stopped/during take-off

The gasoline engine stops when the vehicle is stopped. During

take-off, the electric motor (traction motor) drives the vehicle. At

slow speeds or when traveling down a gentle slope, the engine

is stopped and the motor is used.

1

 During normal driving

The gasoline engine is predominantly used. The electric motor

(traction motor) charges the hybrid battery (traction battery) as

necessary.

 When accelerating sharply

The power of the hybrid battery (traction battery) is added via

electric motor (traction motor) to that of the gasoline engine.

 When braking (Regenerative brake)

The electric motor (traction motor) charges the hybrid battery

(traction battery).

Regenerative braking

In the following situations, kinetic energy is converted to electric energy and

deceleration force can be obtained in conjunction with the recharging of the

hybrid battery (traction battery).

 The accelerator pedal is released while driving with shift position D or B

selected.

 The brake pedal is depressed while driving with shift position D or B

selected.

31

1-1. Hybrid system

Conditions in which the gasoline engine may not stop

The gasoline engine starts and stops automatically. However, the followings

are examples of conditions under which the engine may not stop automati-

cally:

 The gasoline engine is warming up.

 The hybrid battery (traction battery) is being charged.

 The hybrid battery (traction battery) temperature is low or high.

 The temperature setting of the air conditioning system is high.

Charging the hybrid battery (traction battery)

 As the gasoline engine or regenerative brake charges the hybrid battery

(traction battery), the battery does not need to be charged from an out-

side source. However, if the vehicle is left parked for a long time the

hybrid battery will slowly discharge. For this reason, be sure to drive the

vehicle at least once every several months for at least 30 minutes or 16

km (10 miles). If the hybrid battery becomes fully discharged and you are

unable to jump-start the vehicle with the 12-volt battery, contact any

authorized Toyota dealer or repairer, or another duly qualified and

equipped professional.

 If the shift position is in N, the hybrid battery (traction battery) will not be

charged. When driving in heavy traffic, operate the vehicle with the shift

position in D or B to avoid discharging the battery.

Charging the 12-volt battery

P. 478

After the 12-volt battery has discharged or has been changed or

removed

The gasoline engine may not stop even if the vehicle is running on the hybrid

battery (traction battery). If this continues for a few days, contact any autho-

rized Toyota dealer or repairer, or another duly qualified and equipped pro-

fessional.

Sounds and vibrations specific to a hybrid vehicle

There may be no engine sounds or vibration even though the vehicle is able

to move. Always push the P position switch and set the parking brake when

parked.

The following sounds or vibrations may occur when the hybrid system is

operating, and are not a malfunction.

1

 Motor sounds may be heard from the engine compartment.

 Sounds may be heard from the hybrid battery (traction battery) behind

the rear seat when the hybrid system starts or stops.

 Sounds from the hybrid system may be heard when the back door is

open.

 Sounds may be heard from the transmission when the gasoline engine

starts or stops, when driving at low speeds, or during idling.

 Engine sounds may be heard when accelerating sharply.

 Sounds may be heard due to regenerative brake when you press the

brake pedal or release the accelerator pedal.

 Other sounds, such as motors and mechanical noises, may be heard

from the brake system when the brake pedal is depressed.

 Vibration may be felt when the gasoline engine starts or stops.

 You may hear cooling fan sounds coming from the air intake vents behind

the rear seat.

Maintenance, repair, recycling, and disposal

Contact any authorized Toyota dealer or repairer, or another duly qualified

and equipped professional regarding maintenance, repair, recycling and dis-

posal. Do not dispose of the vehicle yourself.

 Hybrid battery air vent

There is an air intake vent on the

side of the rear right seatback for

the purpose of cooling the hybrid

battery (traction battery). If the

vent becomes blocked, the

hybrid battery may overheat,

leading to a reduction in hybrid

battery output.

1

Emergency shut off system

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 when a certain level of impact is detected by the impact sen-

sor. If the emergency shut off system activates, your vehicle will not

restart. To restart the hybrid system, contact any authorized Toyota

dealer or repairer, or another duly qualified and equipped profes-

sional.

37

1-1. Hybrid system

If a warning light comes on or a warning message is displayed, or the

12-volt battery is disconnected

The hybrid system may not start. In that case, try to start the system again. If

the “READY” indicator does not come on, contact any authorized Toyota

dealer or repairer, or another duly qualified and equipped professional.

Electromagnetic waves

 High voltage parts and cables on the hybrid vehicles incorporate electro-

magnetic 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.

 Consult any authorized Toyota dealer or repairer, or another duly quali-

fied and equipped professional before installing or removing third party-

produced radio parts.

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 go off (P. 433). If there is only a small amount of fuel,

the hybrid system may not be able to start. (The minimum amount of fuel to

add to make the low fuel level warning light go out is about 12 L [3.2 gal., 2.7

Imp. gal.], when the vehicle is on a level surface. This value may vary when

the vehicle is on a slope.)

Hybrid battery (traction battery)

The hybrid battery (traction battery) has a limited service life. The lifespan of

the hybrid battery (traction battery) can change in accordance with driving

style and driving conditions.

38

CAUTION

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.

1

 Never touch, disassemble, remove or replace the high voltage parts,

cables and 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.

 Do not subject the service plug to

strong impacts. Also, avoid splashing

large amount of water onto the luggage

compartment, for example while in a

high-pressure car wash.

Hybrid battery (traction 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.

39

1-1. Hybrid system

CAUTION

Emergency shut off system

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

Never touch the parts or cables. (P. 34)

 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.

Road accident cautions

If your vehicle is involved in an accident, observe the following precautions

to reduce the risk of injury.

 Stop the vehicle in a safe place to prevent subsequent accidents. While

depressing the brake pedal, apply the parking brake and push the P posi-

tion switch to stop the 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.

 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. 423)

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.

NOTICE

Hybrid battery air vent

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

battery) may overheat and be damaged.

1

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

from overheating.

 Do not wet or allow foreign substances to enter the air vent as this may

cause a short circuit and damage the hybrid battery (traction battery).

 Do not load a large amount of water such as an aquarium into the vehicle.

If water spills over the hybrid battery (traction battery), the battery may be

damaged.

 When the rear seat belts are in use, make sure to pass them through the

guides (P. 82). Otherwise, the rear seat belts may cover the hybrid bat-

tery air vents.
