■Switching to the hybrid battery (traction battery) charge mode
Press and hold the switch.
Take your hand off the switch
once the hybrid battery charge
mode indicator starts to blink.
The hybrid battery charge mode
indicator illuminates when the
switch to hybrid battery (traction
battery) charge mode is com-
plete.
When the hybrid battery (traction battery) is fully charged
*, the hybrid
battery (traction battery) charge mode is automatically cancele d and the
operation mode will be switched to HV mode.
The hybrid battery (traction battery) charge mode will be cance led by
pressing EV/HV mode selection switch or EV auto mode switch.
*: The maximum charge amount in the hybrid battery (traction batt ery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
■ If the plug-in hybrid system ope ration mode cannot be changed
In the following situations, the plug-in hybrid system operation mode cannot
be changed even if the EV/HV mode selection switch or EV auto mode switch
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
● When electricity needed for EV driving is not remaining (when in EV/EV
auto mode)
● When the traction battery is almost completely charged (hybrid battery [trac-
tion battery] charge mode)
■ When switching from EV mode to another mode using the switch
When the power switch is turned of f, operation mode switching is canceled
and the system returns to EV mode the next time the vehicle is started.
■ Hybrid battery (traction battery) charge mode
●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or cannot
cancel it
• Gasoline engine does not start or stops even after switching to hybrid bat- tery (traction battery) charge mode
● If a load to the system is large, such as when the power consumption of the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.

■If a warning light comes on, 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 your Toyota dea ler.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cann ot be started,
refuel the vehicle with at least enough gasoline to make the lo w fuel level
warning light ( P. 673) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
2.0 gal. [7.5 L, 1.7 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when th e vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporat e 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-p roduced
radio parts.
■ Effect of magnetic forces
If objects that generate strong magnetic forces, such as large speakers, are
placed inside the luggage compartment or installed nearby, the generated
magnetic forces may negatively affect the hybrid system.
■ Hybrid battery (traction batt ery) (lithium-ion battery)
The hybrid battery (traction battery) has a limited service lif e.
The hybrid battery (traction battery) capacity (the ability to hold a charge)
reduces with time and use in the same way as other rechargeable batteries.
The extent at which capacity reduces changes drastically depending on the
environment (ambient temperature, etc.) and usage conditions, such as how
the vehicle is driven and how the hybrid battery (traction batt ery) is charged.
This is a natural characteristic of lithium-ion batteries, and is not a malfunc-
tion. Also, even though the distance that can be driven in EV m ode decreases
when the hybrid battery (traction battery) capacity reduces, ve hicle perfor-
mance does not significantly become worse.
In order to reduce the possibility of the capacity reducing, fo llow the directions
listed on P. 144, “Capacity reduction of the hybrid battery (tr action battery)”.
■ Starting the hybrid system in a n extremely cold environment
When the hybrid battery (traction battery) is extremely cold (b elow approxi-
mately -22 F [-30C]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to the
outside temperature increase etc.

NOTICE
■Hybrid battery (traction battery) air vents
● Make sure not to block the air intake vent with anything, such as a seat
cover, plastic cover, or luggage. If the vents are blocked, the charging/dis-
charging of the hybrid battery (traction battery) may become limited.
● When dust etc. has accumulated in the air intake vent, clean it with a vac-
uum cleaner to prevent the vent from clogging.
● Do not wet or allow foreign substances to enter the air vents a s this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottle s in the
vehicle. If water spills onto the hybrid battery (traction batt ery), the battery
may be damaged. Have the vehicle inspected by your Toyota deale r.
● A filter is installed to the air intake vent. When the filter remains noticeably
dirty even after cleaning the air intake vent, filter cleaning or replacement
is recommended. When cleaning the filter, refer to P. 580.
■ Notice about fuel
● For plug-in hybrid vehicles, fuel may remain in the tank for a long time and
undergo changes in quality depending on the how the vehicle is used.
Refuel at least 5.3 gal. (20 L, 4.4 Imp.gal.) of fuel every 12 months (refuel
a total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 12-mon th period), as
this may affect components of the fuel system or the gasoline engine.
● If the vehicle has not been refueled for a certain amount of time and it is
possible that the quality of the fuel remaining in the tank has changed, “No
new fuel has been added recently. Please refuel” is displayed on the multi-
information display when the power switch is turned to ON mode. If the
message is displayed, refuel the vehicle immediately.

◆Accelerator pedal/brake pedal operation
●Drive your vehicle smoothly. Avoid abrupt acceleration and
deceleration. Gradual accelerat ion and deceleration will make
more effective use of the electric motor (traction motor) witho ut
having to use gaso line engine power.
● Avoid repeated acceleration. Repeated acceleration consumes
hybrid battery (tracti on battery) power, resulting in poor fuel con-
sumption. Battery power can be restored by driving with the
accelerator pedal slightly released.
◆When braking
Make sure to operate the brakes gently and a timely manner. A
greater amount of electrical energy can be regenerated when slow-
ing down.
◆Delays
Repeated acceleration and deceleration, as well as long waits a t
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before leav ing and avoid delays as much a s
possible. When driving in a traffic jam, gently release the brake
pedal to allow the vehicle to mov e forward slightly while avoiding
overuse of the accelerator pedal. Doing so can help control exces-
sive electricity and fuel consumption.
◆Highway driving
● Control and maintain the vehicle at a constant speed. Before
stopping at a toll booth or similar, allow plenty of time to re lease
the accelerator and gently apply the brakes. A greater amount o f
electrical energy can be regenerated when slowing down.
● Electricity consumption will in crease significantly when drivin g at
high speeds in EV mode. If there will be a long distance to the
next external charging point after leaving a freeway, it is rec om-
mended to drive in HV mode while on the freeway and change to
EV mode after leaving the freeway.

■“Traction Battery Cooler”
●When the hybrid battery (traction battery) is above a certain temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Co oler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this s creen, sys-
tem operation becomes possible.
● When charging starts, “Traction Battery Cooler” only operates i f the hybrid
battery (traction battery) temperature is hot.
● The charging indicator is illuminated while “Traction Battery C ooler” is on
standby or operating.
● “Traction Battery Cooler” is implemented for a maximum of approximately
30 minutes. However, when the “Departure” time is set ( P. 158) and there
is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become s horter.
● When there is a small amount of remaining charge in the hybrid battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.
● When the following operations are performed while “Traction Bat tery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.
• A door is opened
• The hood is opened
• The power switch is turned to any mode other than off
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( P. 5 3 1 )
• “Charge Now” is implemented ( P. 1 5 9 )
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
● When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Batt ery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display ( P. 248). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
● “Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of th e remaining
charge of the hybrid battery (traction battery) increases and d ecreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as ch arging by a
charger. The charger that calculates the fee according to charg ing time
causes a charging fee.
