When driving
Hill-start assist control
■Hill-start assist control can be operated when
●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
●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 vehicle 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 e n g a g e h i l l - s t a r t a s s i s t c o n -
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.

Interior features
■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The buzzer will beep and the emergency flashers flash when the doors
have been locked or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)
■Conditions affecting operation
→P. 1 1 9
■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. 5 6 2 )
■While the Remote Air Conditioning 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. 1 2 3
■When the electronic key battery is fully depleted
→P. 1 2 3
■Customization
Setting (e.g. Operation using the on the wireless remote control) can
be changed.

PRIUS PHV_OM_OM47818U_(U)
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 park ing 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-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure 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 efficiency 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 maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Yo u r v e h i c l e h a s a l s o b e e n e q u i p p e d w i t h a T P M S ( t i r e p r e s s u r e w a r n i n g
system) malfunction indicator to indicate 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 detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.

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. 8 0 .
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. 8 0 .
Check that the plug is
not connected to a
power strip and that an
extension cord, multi-
outlet etc. is not being
used.
