slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
(traction battery) becomes fully dis- charged and you are unable to start the hybrid system, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Charging the 12-volt battery
 P. 4 7 4
■After the 12-volt battery has dis-
charged or when the terminal has been removed and installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery (traction battery). If this
continues for a few days, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer.
■Sounds and vibrations specific to a hybrid electric vehicle
There may be no engine sound or vibra-
tion even though the vehicle is able to move with the “READY” indicator is illu-minated. For safety, apply the parking
brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may
occur when the hybrid system is operat- ing and are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) under the rear seats when the hybrid system
starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted from the hybrid battery (traction battery), under the rear seats, when the hybrid
system is started or stopped.
●Sounds from the hybrid system may
be heard when the back door is open.
●Sounds may be heard from the trans-
mission when the gasoline engine
starts or stops, when driving at low
speeds, or during idling.
●Engine sounds may be heard when
accelerating sharply.
●Sounds may be heard due to regener-
ative braking when the brake pedal is depressed or as the accelerator pedal is released.
●Vibration may be felt when the gaso-line engine starts or stops.
●Cooling fan sounds may be heard from the air intake vent on the side of
the lower part of the rear left seat.
■Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any reli- able repairer regarding maintenance, repair, recycling and disposal. Do not
dispose of the vehicle yourself.
■Customization
Some functions can be customized. ( P.494)
When the gasoline engine is off
while driving, a sound is produced
to warn pedestrians, people riding
bicycles or other people and vehi-
cles in the surrounding area that
the vehicle is approaching. The
pitch of the sound adjusts accord-
ing to vehicle speed. When vehicle
speed is approximately 25 km/h (16
mph) or more, the warning system
turns off.
■Acoustic vehicle alerting system
In the following cases, the acoustic vehi- cle alerting system sound may be diffi-cult for pedestrians, people riding
bicycles or other people and vehicles in

WARNING
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
●If a fire occurs in the hybrid electric vehicle, leave the vehicle as soon as possible. Never use a fire extin-
guisher 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 (2WD
models) or four wheels (AWD mod- els) 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.429)
●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 possi- ble.
●Do not touch the battery if liquid is leaking from or adhering to it. If electrolyte (carbonate ester-based
organic electrolyte) from the hybrid battery (traction battery) comes into contact with the eyes or skin, it
could cause blindness or skin wounds. In the unlikely event that it comes into contact with the eyes or
skin, wash it off immediately with a large amount of water, and seek immediate medical attention.
●If electrolyte is leaking from the hybrid battery (traction battery), do not approach the vehicle. Even in
the unlikely event that the hybrid battery (traction battery) is dam-aged, the internal construction of
the battery will prevent a large amount of electrolyte from leaking out. However, any electrolyte that
does leak out will give off a vapor. This vapor is an irritant to skin and eyes and could cause acute poi-
soning if inhaled.
●Do not bring burning or high-tem-
perature items close to the electro- lyte. The electrolyte may ignite and cause a fire.
■Hybrid battery (traction battery)
●Your vehicle contains a sealed lith-
ium-ion battery.
●Never resell, hand over or modify
the hybrid battery. To prevent acci- dents, hybrid batteries that have been removed from a disposed
vehicle are collected through any authorized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. Do not dispose of the bat- tery yourself.
Unless the battery is properly col-
lected, the following may occur,
resulting in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is
hazardous 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
electric 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.

There is an air intake vent under
the left side of the rear seat for the
purpose of cooling the hybrid bat-
tery (traction battery). If the vent
becomes blocked, the hybrid bat-
tery (traction battery) input and out-
put may be reduced.
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

WARNING
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 with-out the hybrid battery having been
removed, there is a danger of seri- ous 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 any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer. If the hybrid bat-
tery is not disposed 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 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 any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
Hybrid battery (traction bat-
tery) air intake vent
NOTICE
■Hybrid battery (traction battery) air intake vent
●Make sure that the air intake vent is not blocked, such as by a seat cover, plastic cover, or luggage. If
the vent is blocked, the hybrid bat- tery (traction battery) input and out-put may be restricted, possibly
leading to a malfunction.
●Clean the air intake vent regularly
to prevent the hybrid battery (trac- tion battery) from overheating.
●Do not get water or foreign materi-als in the air intake vent as this may cause a short circuit and damage
the hybrid battery (traction battery).
●A filter is installed to the air intake
vent. When the filter remains noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. Refer to P.406 for details on how to clean the filters.

■Fuel gauge and driving range dis-play
The fuel gauge and driving range dis- play are linked. If the fuel gauge and driving range display do not update after
refueling a small amount, they can be updated by performing the following pro-cedure:
1 Stop the vehicle on a level surface.
Wait until the fuel in the fuel tank stabi- lizes.
2 Press the display change button to change the odometer and trip meter
display to the odometer.
3 Turn the power switch off.
4 While pressing and holding the dis- play change button, turn the power switch to ON.

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 downshift again, causing rapid and
excessive engine braking and possi- bly an accident resulting in death or injury.
