CAUTION
■ General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that dis-
tracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.
■ Disposal of the hybrid battery (traction battery)
If your vehicle is disposed of without the hybrid battery (traction battery) hav-
ing 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 (traction battery) must be disposed
of by your Toyota dealer or a qualified service shop. If the hybrid battery
(traction battery) is not disposed of properly, it may cause electric shock that
can result in death or serious injury.

■
When stopped/during start off
The gasoline engine stops
* when the vehicle is stopped. During
start off, the electric motor (tra ction motor) drives the vehicle. At
slow speeds or when traveling down a gentle slope, the engine
is stopped
* and the electric motor (traction motor) is used.
When shift position is in N, the hybrid battery (traction battery)
will not be charged. Thus, shift to P when the vehicle is stopped.
In addition, when driving in heavy traffic, use D or B.
*: However, when the hybrid battery (traction battery) need to be charged or while the engine is being warmed up, the gasoline
engine may not stop automatically. ( P. 31)
■ During normal driving
The gasoline engine is predominantly used. The electric motor
(traction motor) charges the hybr id battery (traction battery) as
necessary.
■ When accelerating sharply
When the accelerator pedal is depressed heavily, the power of
the hybrid battery (traction battery ) is added to that of the gaso-
line engine via the electric motor (traction motor).
■ When braking (regenerative braking)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

30 1-1. Hybrid system

Vehicle proximity notification system
When driving with the gasoline engine stopped, a sound, which
changes in accordance with the dr iving speed, will be played in order
to warn people nearby of the vehicle’s approach. The sound will stop
when the vehicle speed exceeds a pproximately 15 mph (25 km/h).
■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 the shift position in D
or B.
● The brake pedal is depressed while driving with the shift position in D or
B.
■ Hybrid System Indicator
Hybrid System Indicator represents the
hybrid system power output and regener-
ative charging. (
P. 201)

■
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions
*:
● During gasoline engine warm-up
● When the temperature of the hybrid battery (traction battery) is high or
low
● During hybrid battery (traction battery) charging
● When the heater is switched on
*: Depending on the circumstances, the gasoline engine may also not stop
automatically in situations other than those above.
■ Charging the hybrid battery (traction battery)
● As the gasoline engine charges the hybrid battery (traction battery), the
battery does not need to be charged from an outside source. However, if
the vehicle is left parked for a long time the hybrid battery (traction bat-
tery) will slowly discharge. For this reason, be sure to drive the vehicle at
least once every few months for at least 30 minutes or 10 miles (16 km).
If the hybrid battery (traction battery) becomes fully discharged and you
are unable to jump-start the vehicle with the 12-volt battery, contact your
Toyota dealer.
● If the shift position is in N, the hybrid battery (traction battery) will not be
charged. Always shift the shift position in P when the vehicle is stopped.
When driving in heavy traffic, operate the vehicle with the shift position in
D or B to avoid discharging the hybrid battery (traction battery).
■ Charging the 12-volt battery
 P. 482
■ After the 12-volt battery has di scharged 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 your Toyota
dealer.

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
● The brake system operation sound heard from the front of the vehicle
when the driver’s door is opened.
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
● 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 braking when the brake pedal
is depressed and accelerator is loosened.
● 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.
● Cooling fan sounds may be heard from the air intake vent. (
P. 35)
● The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

Hybrid battery (traction battery) air vent
There is an air intake vent under
the rear seat for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent become
blocked, the hybrid battery (trac-
tion battery) may overheat, lead-
ing to a reduction in hybrid
battery (traction battery) output.
Emergency shut off system When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize t he risk of electrocution and fuel
leakage. If the emergency shut off sy stem activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.

■If a warning light comes on, a warn ing 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 your Toyota dealer.
■ 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 ( P. 449) go off. 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 1.8 gal. [7 L,
1.5 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
■ 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.
■ 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.

CAUTION
■Road accident cautions
If your vehicle is involved in an accident, 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 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 the fluid 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 possible, 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 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 an electricity leakage leading to a fire. ( P. 435)
● 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 nicke l-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.
