When driving
■Sounds and vibrati ons 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.
■ Electric power steering system warning light (warning buzzer)

Hill-start assist control
■Hill-start assist contro l operating conditions
● The system operates in the following situations:
• The shift position is in a position other than P.
• The parking brake is not applied.
• The accelerator pedal is not depressed.
● Hill-start assist control cannot be operated while the slip indicator light is
illuminated.
■ Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
● Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
● If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicl e to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To engage hill-start assist con-
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

■ When using the Remote Air Conditioning System
A charging message will be displayed on the multi-information display. Dif-
ferent messages will be displayed depending on when the Remote Air Con-
ditioning System was started (after charging or during charging).
( P. 570)
■ While the Remote Air Conditio ning System is operating
● Depending on the operating condition of the Remote Air Conditioning
System, the electric fan may spin and an operating noise may be heard.
However, this does not indicate a malfunction.
● The Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights,
windshield wipers) are in operation or if the charge level of the 12-volt
battery becomes low.
■ Electronic key battery depletion
P. 127
■ When the electronic key battery is fully depleted

CAUTION
■When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
●When using a floor jack, follow the instructions of the manual provided with
the jack.
● Do not use the jack that was supplied with your vehicle.
● Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
● Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
● Do not start the hybrid system while the vehicle is supported by the floor
jack.
● Stop the vehicle on level, firm ground, firmly set the parking brake and shift
the shift position to P.
● Make sure to set the floor jack properly at the jack point.
Raising the vehicle with an improperly positioned floor jack will damage
the vehicle and may cause the vehicle to fall off the floor jack.
●Lift up the vehicle using a floor jack
such as the one shown in the illustra-
tion.

CAUTION
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-ti re pressure warning system) that
illuminates a low tire pressure telltal e (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressu re telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel effi ciency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire main tenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illu mination of the TPMS low tire pressure telltale (tire
pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warning
system) malfunction indicator to indi cate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system det ects a malfunction, the telltale will
flash for approximately one minute an d then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indi cator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

Warning messageDetailsCorrection procedure
(Flashes) The hybrid battery (traction
battery) is low.
A buzzer also sounds. When stopping the
vehicle for a long

the shift position to
P. The hybrid bat-
tery (traction bat-
tery) cannot be
charged with the
shift position in N.
(Flashes) The hybrid battery (traction
battery) power has dropped
because a long period of time
has elapsed after shifting the
shift position to N.
A buzzer also sounds. Restart the hybrid
system when start-
ing the vehicle.
(Flashes) The transmission is out of P
when attempting to start the
hybrid system.
Shift the shift posi-
tion to P before
pressing the
“POWER” switch.
(Flashes) The driver’s door is opened
when the shift position is in N,
D or B with the hybrid system
on.
Shift the shift posi-
tion to P.

MessageDetailsCorrection
procedure
Charging has been inter-
rupted because the plug
has been disconnected
or some kind of power
failure has occurred. Charging has not fin-
ished properly.
Refer to the procedures
on P. 85 and perform
charging again.
The vehicle can be used
even if charging has not
finished. However, the
distance that can be
driven in EV mode
decreases.
One of the following situ-
ations has occurred:
• The charging connector is not properly inserted
• The latch release button has been pressed and
held
• The charging connector has been disconnected Reinsert the charging
connector to restart
charging.
Charging has been inter-
rupted by a malfunction
in the charging system. Stop charging immedi-
ately, and contact your
Toyota dealer.
Also, driving is possible
when the hybrid system
has been started.

572 5-2. Steps to take in an emergency
PRIUS PHV_OM_OM47A11U_(U)
MessageDetailsCorrection procedure
Charging has been
stopped because of the
high energy consumption
of electrical compo-
nents, such as the head-
lights. Switch the electrical
appliance OFF, and
restart charging by fol-
lowing the procedure on
P. 85.
If the message is still
displayed, the 12-volt
battery may have a low
charge.
In this event, turn the
“POWER” switch OFF
approximately 15 min-
utes after starting the
hybrid system, and
restart charging.
Charging has been
stopped because of
extremely low voltage,
possibly caused by the
plug not being inserted
correctly. Check that the plug is
inserted correctly, and
restart charging by fol-
lowing the procedure on
P. 85.
Check that the plug is
not connected to a
power strip and that an
extension cord, multi-
outlet etc. is not being
used.
