Hybrid battery (traction battery) air vents
● Do not put foreign objects near the air vents. The hybrid battery (traction
battery) may overheat, leading to a reduction in hybrid battery (traction
battery) output or a malfunction.
● Clean the air vents regularly to prevent the hybrid battery (traction battery)
from overheating.
● Do not wet or allow foreign substances to enter the air vents 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.
● If the rear seat belt becomes separated from the guide ( P. 150), it could
obstruct the hybrid battery (traction battery) air vent. Set the rear seat belt
into the guide to use.
■ 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 6 months (refuel a
total of at least 5.3 gal. [20 L, 4.4 Imp.gal.] over a 6-month period), as this
may affect components of the fuel system or the gasoline engine.

Plug-in hybrid vehicle driving tips
For economical and ecological driving, pay attention to the following
points:
■ Using EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV
mode when driving on highways (or freeways) can help con-
serve fuel and electricity. ( P. 3 7 )
■ Using Eco drive mode
When using Eco drive mode, a torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving fuel a nd electricity economy. ( P. 247)
■ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System
Indicator within Eco area. ( P. 268)
■ When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained when slow-
ing down.
■ Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to high fuel and electricity consumption.
Check traffic reports before l eaving and avoid delays as much
as possible. When encountering a delay, gently release the
brake pedal to allow the vehicle to move forward slightly while
avoiding overuse of the accelerator pedal. Doing so can help
control excessive electric ity and fuel consumption.

PRIUS PHV_OM_OM47787U_(U)
CAUTION
■Routine inspection
Check the following points regularly.
If use is continued without inspection, fire or electric shock may occur,
possibly resulting in death or serious injury.
● The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged
● The outlet has not been damaged
● The plug does not get extremely hot during use
● The tip of the plug has not been deformed
● The plug is not dirtied by dust etc.
Inspect the plug after removing it from the outlet.
■ Maintaining the charging cable
When the cable is dirty, first remove the dirt with a hard, wringed cloth, and
then wipe the cable with a dry cloth. Do not wash with water, as doing so
could cause a fire or electrical shock when charging, which could lead to
death or serious injury.
■ When not using the charging cable for a long time
Remove the plug from the outlet. Dust could accumulate on the plug or in
the outlet, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.

When driving
CAUTION
■
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns that require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
● The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not continue to drive the vehicle. If the brake
system warning light (red indicator) comes on while driving, immediately
stop the vehicle in a safe place and contact your Toyota dealer.

When driving
■
Selecting a driving mode
The following modes can be selected to suit driving conditions:
Eco drive mode
Suitable for improving the fuel economy, because the torque cor-
responding to the accelerator pedal depression amount can be
generated more smoothly than it is in normal conditions and the
operation of the air conditioning system (heating/cooling) will be
minimized.
When the “ECO MODE” switch is pressed, the “ECO MODE” indicator
comes on.
Power mode
Use when high levels of response and feeling are desirable,
such as when driving in mountainous regions or when overtak-
ing.
When the power mode switch is pressed, the power mode indicator
comes on.

■
Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( P. 247) To improve air
conditioning performance, adjust the fan speed or turn off Eco drive mode.
■ For the shift positions
● When the “POWER” switch is off, the shift position cannot be changed.
● When the “POWER” switch is in ON mode (the hybrid system is not oper-
ating), the shift position can only be changed to N. The shift position will
be changed to N even if the shift lever is shifted to D or R and held in that
position.
However, immediately after turning the “POWER” switch to ON mode,
the shift position may not change to N.
● When the “READY” indicator is on, the shift position can be changed
from P to D, N or R.
● When the “READY” indicator is flashing, the shift position cannot be
changed from P to other position even if the shift lever is operated. Wait
until the “READY” indicator changes from a flashing to a solid light, and
then operate the shift lever again.
● The shift position can only be changed to B directly from D.
In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the shifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
● Situations where the shifting operation will be disabled:
• When an attempt is made to change the shift position from P to other
position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B by moving the shift lever.
• When an attempt is made to change the shift position from P to another position by moving the shift lever while the charging cable is connected
to the vehicle.

PRIUS PHV_OM_OM47787U_(U)
■Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
● A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may
be heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■ Operation of the air conditio ning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode ( P. 247)
● Customize the air conditioning control of Eco drive mode. ( P. 639)
■ When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Air conditioning odors
● During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.
■ Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
