46 1-1. Plug-in hybrid system
PRIUS PHV_OM_OM47818U_(U)
Hybrid warning messageA message is automatically displayed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( P. 546)
■If a warning light comes on, a warn ing 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 dealer.
■ Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light ( P. 537) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 1.9 gal. [7.1 L,
1.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

84 1-2. Charging
PRIUS PHV_OM_OM47818U_(U)
Confirm that the charging indi-
cator is illuminated. (When the
charging timer function is in
use, the light will turn off sev-
eral seconds after illuminat-
ing.)
Charging will not start if the
charging indicator does not illu-
minate when the charging con-
nector is inserted. (P. 9 9 )
The amount of time until charg-
ing is completed can be
checked on the energy monitor
by turning the “POWER” switch
to ON mode. ( P. 89)
The error warning indicator of
the CCID (Charging Circuit
Interrupting Device) has illumi-
nated during charging:
P. 102
The charging indicator will turn
off when charging is com-
pleted.

■Alarms and warning lights
A combination of exterior and interior alarms as well as warning lights are
used to prevent theft of the vehicle and accidents resulting from erroneous
operation. Take appropriate measures in response to any warning message
shown on the multi-information display. ( P. 556)
The following table describes circumstances and correction procedures
when only alarms are sounded.

PRIUS PHV_OM_OM47818U_(U)
CAUTION
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
■ Seat belt pretensioners
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the seat belt
pretensioner for the front passenger’s seat may not activate in the event of
a collision.
● If the pretensioner has activated, the SRS warning light will come on. In
that case, the seat belt cannot be used again and must be replaced at
your Toyota dealer.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your
shoulder. The belt should be kept away from your neck, but not falling off
your shoulder. Failure to do so could reduce the amount of protection in an
accident and cause death or serious injuries in the event of a sudden stop,
sudden swerve or accident. ( P. 157)
