WARNING
■Hybrid battery (traction battery)
● Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected 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 haz-
ardous 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
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 dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.
NOTICE
■Hybrid battery (traction battery) air intake vent
● Do not place objects that will block the air intake vent. The hybrid battery
(traction battery) may overheat and be damaged.
● Clean the air intake vent regularly to prevent the hybrid battery (traction
battery) from overheating.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.

Cruising range
Displays the estimated maximum distance that can be driven
with the quantity of fuel remaining.
• This distance is computed based on your average fuel consumption.As a result, the actual distance that can be driven may differ from that
displayed.
• When only a small amount of fuel is added to the tank, the display
may not be updated.
Vehicles without a smart key system:
when refueling, turn the engine switch to the “LOCK” position. If the
vehicle is refueled without turning the engine switch to the “LOCK”
position, the display may not be updated.
Vehicles with a smart key system:
when refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.

Eco driving conditions display
Driving conditions are displayed in 5 stages and divided into 3 catego-
ries: start, cruise and stop. Every time the vehicle is stopped, the score
is displayed. (Every time the vehicle is accelerated the score that was
last displayed is reset. Accumulative scores are not calculated.)

“ECO Savings Record”
If the fuel consumption compar-
ison is input in “ECO Savings”,
the savings history will be dis-
played. If the fuel consumption
comparison is not input, fuel
cost history will be displayed.
Fuel costs for the current
month, the last 3 months and
the same month last year are
displayed, enabling a compari-
son to be made.
If the dollar amount exceeds $ 100, the numerical value will be dis-
played on the graph.
Charge area
Shows energy regeneration* sta-
tus. Regenerated energy will be
used to charge the hybrid battery
(traction battery).
*: When used in this manual, “regen-
eration” refers to the conversion of
energy created by the movement
of the vehicle into electrical energy.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various con-
ditions.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
Power area
Shows that the driving power is more than the upper limit of Eco driving.
(during full power driving etc.)
Keeping the indicator within Eco ar ea can help Eco-friendly driving.

Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environmental fac-
tors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.
■ When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
WARNING
■Eco score
Eco score should be used as a guide only. Always drive safely in accor-
dance with road and traffic conditions.
■ The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This l ag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
■ Cautions during setting up the display
As the hybrid system needs to be running during setting up the display,
ensure that the vehicle is parked in a place with adequate ventilation. In a
closed area such as a garage, exhaust gases including harmful carbon
monoxide (CO) may collect and enter the vehicle. This may lead to death or
a serious health hazard.

■Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may not
reach the highest level (level 8). However, this does not indicate a malfunc-
tion.
■ Resetting the consumption data (audio system)
Selecting “Clear” on the “Trip Information” screen will reset the fuel consump-
tion and the regenerated energy for the past 15 minutes. Selecting “Clear” on
the “Past Record” screen will reset the past records and best past fuel con-
sumption. Selecting “Yes” on the following screen will confirm resetting of all
the data.
■ Updating the past record data (audio system)
Selecting “Update” on the “Past Record” screen will update the past record
data.

Key battery depletion
Vehicles without a smart key system
If the wireless remote control function does not operate, the battery may be
depleted. Replace the battery when necessary. (→ P. 448)
Vehicles with a smart key system
● The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin when the hybrid
system stops. ( →P. 499)
● As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms indi-
cate that the electronic key battery may be depleted. Replace the battery
when necessary. ( →P. 448)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
