40 1-1. Hybrid system
PRIUS_OM_OM47A17U_DVD_(U)
■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. 508) 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.)
■ Electromagnetic waves
●High voltage parts and cables on the hybrid vehicles incorporate electro-
magnetic shielding, and therefore emit approximately the same amount
of electromagnetic waves as conventional gasoline powered vehicles or
home electronic appliances.
● Your vehicle may cause sound interference in some third party-produced
radio parts.
■ Hybrid battery (traction battery)
The hybrid battery (traction battery) has a limited service life. The lifespan of
the hybrid battery (traction battery) can change in accordance with driving
style and driving conditions.

68 1-3. Opening, closing and locking the doors
PRIUS_OM_OM47A17U_DVD_(U)
■Operation signals
A buzzer sounds and the emergency flashers flash to indicate that the doors
have been locked/unlocked. (Locked: Once; Unlocked: Twice)
■ When the door cannot be locked by the lock sensor on the upper part
of the door handle
■ 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. 531)
The following table describes circumstances and correction procedures
when only alarms are sounded.
If the door will not lock even when the
topside sensor area is touched, try touch-
ing both the topside and underside sen-
sor areas at the same time.

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. 1 1 1 )

130 1-5. Opening and closing the windows and moon roof
PRIUS_OM_OM47A17U_DVD_(U)
■Jam protection function
If an object is detected between the moon roof and the frame while closing
or tilting down, travel is stopped and the moon roof opens slightly.
■ To reduce moon roof wind noise
When the moon roof is opened automatically, it will stop slightly before the
fully open position. Driving with the moon roof in this position can help
reduce wind noise.
■ Sunshade
The sunshade can be opened and closed manually. However, the sunshade
will open automatically when the moon roof is opened.
■ Solar Panel
The solar panel contains solar cells, and produces energy to operate the
Solar Ventilation System by receiving sunlight.
■ Moon roof open warning buzzer
The buzzer sounds when the “POWER” switch is turned off and the driver’s
door is opened with the moon roof open.
■ If the moon roof cannot be closed
If the moon roof cannot be closed, such as when the jam protection function
activates accidentally due to a malfunction, pressing and holding “CLOSE”
switch closes the moon roof.
After this, to make the automatic opening function and jam protection func-
tion available again, press and hold the “OPEN” switch until the moon roof
opens fully and then closes slightly.
If the functions do not activate, contact your Toyota dealer.
