PRIUS c_U (OM52E68U)
There is an air intake vent on the
side of the lower part of the rear
left seat for the purpose of cooling
the hybrid battery (traction bat-
tery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
When a certain level of impact is detected by the impact sensor, the
emergency shut off system blocks the high voltage current and stops
the fuel pump to minimize the risk of electrocution and fuel leakage. If
the emergency shut off system activates, your vehicle will not restart.
To restart the hybrid system, contact your Toyota dealer.
A message is automatically displayed when a malfunction occurs in
the hybrid system or an improper operation is attempted.
If a warning message is shown on
the multi-information display, read
the message and follow the
instructions. (P. 449)

■If a warning light comes on, a warning message is displayed, or the 12-
volt battery has been disconnected
The hybrid system may not start. In this 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. 443) go off. If there is only a small amount of fuel, the
hybrid system may not be able to start. (The standard amount of fuel is about
1.3 gal. [5.0 L, 1.1 Imp. gal.] when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is
inclined.)
■ Electromagnetic waves
●High voltage parts and cables on hybrid vehicles incorporate electromag-
netic shielding, and therefore emit approximately the same amount of elec-
tromagnetic 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.

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables or connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into contact
with your skin or eyes, wash it off immediately with a large amount of water
or, if possible, boric acid solution. Seek immediate medical attention.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with the front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. ( P. 433)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

WARNING
■Hybrid battery (traction battery)
●Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be
aware of these dangers.
● If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by your
Toyota dealer or a qualified service shop. If the hybrid battery is not dis-
posed of properly, it may cause electric shock that can result in death or
serious injury.
NOTICE
■Hybrid battery (traction battery) air intake vent
●Do not place objects that will block the air intake vent. The hybrid battery
(traction battery) may overheat and be damaged.
● Clean the air intake vent regularly to prevent the hybrid battery (traction
battery) from overheating.
● Do not get water or foreign materials in the air intake vent 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.

Cruising range
Displays the estimated maximum distance that can be driven
with the quantity of fuel remaining.
• This distance is computed based on your average fuel consumption.As a result, the actual distance that can be driven may differ from that
displayed.
• When only a small amount of fuel is added to the tank, the display may not be updated.
Vehicles without a smart key system:
when refueling, turn the engine switch to the “LOCK” position. If the
vehicle is refueled without turning the engine switch to the “LOCK”
position, the display may not be updated.
Vehicles with a smart key system:
when refueling, turn the “POWER” switch off. If the vehicle is refueled
without turning the “POWER” switch off, the display may not be
updated.

*: When used in this manual, “regen-
eration” refers to the conversion of
energy created by the movement
of the vehicle into electrical energy.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various con-
ditions.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
Power area
Shows that the driving power is more than the upper limit of Eco driving.
(during full power driving etc.)
Keeping the indicator within Eco area can help Eco-friendly driving.

When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
WARNING
■Eco score
Eco score should be used as a guide only. Always drive safely in accor-
dance with road and traffic conditions.
■ The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear
number appearing on the display. This lag could cause the driver to down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
■ Cautions during setting up the display
As the hybrid system needs to be running during setting up the display,
ensure that the vehicle is parked in a place with adequate ventilation. In a
closed area such as a garage, exhaust gases including harmful carbon
monoxide (CO) may collect and enter the vehicle. This may lead to death or
a serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is oper-
ating while setting up the display features.
