■Charging timer function
By using the charging timer function, deterioration of the hybrid bat-
tery (traction battery) charge can be suppressed, and off-peak elec-
tricity can be used effectively.
●A charging time can be assigned by setting the charging start time
or finish time.
●Once the time has been set, the time can be assigned again next
time simply by pressing the charging timer switch.
■Setting the charging timer function
Stop the vehicle and press the
charging timer switch.
The multi-information display will
switch to the charging timer dis-
play.
If not changing the set time: go to
Press and hold the charging
timer switch.
The time display will change from
solid to flashing.

■Safety functions
●The hybrid system will not start while the charging cable is attached to
the vehicle, even if the “POWER” switch is operated.
●If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving will not be
possible.
●When the charging cable is connected to the vehicle, the shift position
cannot be changed from P to another position.
●If the latch release button is pressed, charging will not begin even if the
charging cable is connected.
Also, charging will be stopped if the latch release button is pressed and
held for several seconds during charging. When restarting charging, rein-
sert the charging connector after pulling it out, and check that the charg-
ing indicator illuminates.

How to operate the power (ignition) switch
■Starting the hybrid system
Check that the charging cable is disconnected.
Check that the parking brake is set.
Firmly depress the brake pedal.
Check that the “POWER” switch indicator turns green. If the indica-
tor does not turn green, the hybrid system cannot be started.
When the shift position is N, the hybrid system cannot start. Shift the
shift position to P when starting the hybrid system.
Press the “POWER” switch.
The hybrid system can be started
from any “POWER” switch mode.
Continue depressing the brake
pedal until the hybrid system is
completely started.
Check that the “READY” indicator is on.
If the “READY” indicator changes from a flashing light to a solid light
and the buzzer sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if the
engine is stopped. (The gasoline engine starts or stops automatically
in accordance with the state of the vehicle.)

4. Things you must know
PRIUS PHV_QG_OM47788U_(U)
■When continually using EV mode only
After driving for approximately 124 miles (200 km) with the gasoline engine
off, the gasoline engine may start for a short amount of time in order to pro-
tect the system.
■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.
CAUTION
■While driving
Because there is no engine noise when the vehicle is being driven using the
electric motor, pedestrians in the vicinity may not notice the vehicle. Even
though the vehicle is equipped with the vehicle proximity notification system,
drive with care as pedestrians in the vicinity may still not notice the vehicle if
the surrounding area is noisy.

■When in HV mode
The vehicle can be used in the same way as a standard hybrid
vehicle.
In HV mode, controls are primarily carried out as follows in
accordance with the driving conditions.
●The gasoline engine stops when the vehicle is stopped.
●During start off, the electric motor (traction motor) drives the
vehicle.
●During normal driving, the gasoline engine and electric motor
(traction motor) are controlled effectively, and the vehicle is
driven with optimum fuel efficiency. A l s o , w h e n n e c e s s a r y, t h e
electric motor (traction motor) operates as an electrical gener-
ator to charge the hybrid battery (traction battery).
●When the accelerator pedal is depressed heavily, drive force
from both the gasoline engine and the electric motor (traction
motor) is used to accelerate.
■When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery
(traction battery).
The EV driving range can be extended by actively using this
regenerative braking to store electricity in the hybrid battery
(traction battery).
Moreover, as fuel consumption is also reduced when in HV
mode, the regenerative braking system can be used effectively.

■When continually using EV mode only
After driving for approximately 124 miles (200 km) with the gasoline engine
off, the gasoline engine may start for a short amount of time in order to pro-
tect the system.
■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.
■If the vehicle is not used for a long time
The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(→P. 5 9 4 )
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, start the hybrid system at least once every 2 or 3
months, and turn the “POWER” switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the “POWER” switch can be turned to OFF without any further action.)

■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) behind
the rear seat 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 you press the
brake pedal or release the accelerator pedal.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent. (→P. 4 5 )
●The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

Hybrid battery (traction battery) air vents
There are air intake vents on the
side of the rear right seatback
and on the front corner of the left
rear seat cushion for the purpose
of cooling the hybrid battery
(traction battery). If the vents
become blocked, the hybrid bat-
tery (traction battery) may over-
heat, leading 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 system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel
leakage. If the emergency shut off system activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.

ing indicator illuminates.
■For correct operation of the charging timer function
Check the following points.
●Check that the time is correct.
●Check that the “POWER” switch is OFF.
●Do not use a connector which has an electricity interruption function
(including timer functions).
(Use a connector which supplies electricity normally.)
■Automatic cancelation of the charging timer function
●If the Remote Air Conditioning System is operated while the charging
cable is connected, the charging timer function will be canceled. Charg-
ing will commence after the Remote Air Conditioning System has been
turned off.
●Charging will not commence if the “POWER” switch is not OFF, even at
the set time.
