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 will hurt or kill you,
your occupants or others.
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, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to
children.
■ Dispose of the hybrid battery (traction battery)
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 of that your vehicle
must be disposed of, the hybrid battery must be disposed of your Toyota
dealer or a qualified service shop. If the hybrid battery is not disposed of
properly, they may cause electric shock that can result in death or serious
injury.

■
Regenerative braking
The motor generator converts kinetic energy to electric energy when:
●The accelerator pedal is released.
● The brake pedal is depressed with the shift lever in D or R.
■ 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
● During hybrid battery (traction battery) charging
● During low or high hybrid battery (traction battery) temperature
■ Charging the 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 will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every
several months for at least 30 minutes or 10 miles (16 km). If the hybrid
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 lever is in N, the hybrid battery (traction battery) will not be
charged. When driving in heavy traffic, operate the vehicle with the shift
lever in D to avoid discharging the battery.
■ During normal driving
The gasoline engine is predomi nantly used. The electric motor
(traction motor) charges the hybrid 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 braking)
The electric motor (traction mo tor) charges the hybrid battery
(traction battery).

32 1-1. Hybrid system
●To help prevent the 12-volt battery from becoming discharged, drive the
vehicle at least once a month, and operate the accessories only when
the “READY” indicator is on. When parking the vehicle, make sure the
doors is closed and all lights are turned off.
■ 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. Always put the shift lever in P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating, and are not a malfunction:
●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 may be heard from the transaxle when the hybrid system starts
or stops, or while the vehicle is idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when you press the
brake pedal.
● Vibration may be felt when the gasoline engine starts or stops.
● You may hear cooling fan sounds coming from the air intake vents below
the second seat.
■ Maintenance, repair, recycling, and disposal
Contact your Toyota dealer regarding maintenance, repair, recycling and
disposal. Do not dispose of the vehicle yourself.

High voltage components
Take care when handling the hybrid system, as it contains a high volt-
age system (about 650 V at maximu m) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle. Air conditioning compressor

■Hybrid battery air vents
There are air intake vents under
the second seats to cool the
hybrid battery (traction battery).
If the vents become blocked, the
hybrid battery may overheat,
leading to a reduction in hybrid
battery output.
Emergency shut off system
The emergency shut off system bloc ks off the high voltage current
and stops the fuel pump to minimize the risk of electrocution and fuel
leakage when a certain level of impa ct is detected by the impact sen-
sor. If the emergency shut off syste m activates, your vehicle will not
restart. To restart the hybrid sy stem, contact your Toyota dealer.
Energy monitor/consumption screen
You can view the status of your
hybrid system on the multi-infor-
mation display (→P. 35) and the
navigation system screen ( →P.
35, 37). The following images
are examples only, and may vary
slightly from actual conditions.

Hybrid warning messageA message is automatically displa yed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( →P. 509)
■If a warning light comes on or a wa rning 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.
■ When refueling, the fuel filler door may take a few moments to open
As part of emission system operation, it may take up to 10 seconds for the
fuel filler door to automatically release after the opener switch is pressed.
Before refueling is possible, a message will be shown on the multi-informa-
tion display. ( →P. 118)
■ 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. 503) 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 2.5 gal. [9.8 L,
2.1 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)
■ If the master warning light comes on when the shift lever is in R
Immediately stop the vehicle in a safe place and shift the shift lever out of R
to display the message.

■Road accident cautions
Observe the following precautions to reduce the risk of injury.
●Pull your vehicle off the road, put the shift lever in P, apply the parking
brake, and turn the hybrid system is off.
● 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 four 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. 491)
■ 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.
■ If the system activates
●Carefully check to see if there are exposed high voltage parts or cables.
Never touch the parts or cables. (
→P. 33)
● 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.
