For safety and security
*: This function can only be used in
the mainland U.S.A. It cannot be
used in other states and territo-
ries, including Alaska and Hawaii.
This system operates based on
the driving situation and traffic
information to enhance fuel
economy.
For details about Predictive effi-
cient drive, refer to “NAVIGA-
TION AND MULTIMEDIA
SYSTEM OWNER’S MANUAL”.
■Predictive deceleration sup-
port
 When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, “Refer-
ence operation range” ( ) of
the ECO Accelerator Guid-
ance ( P.109) on the multi-
information display will be
turned off to encourage the
driver to reduce excessive
acceleration.
 The engine braking force will be increased according to the
driving conditions to more effi-
ciently charge the hybrid bat-
tery (traction battery) after the
accelerator pedal is released.
■Predictive SOC* control
*: SOC means state of charge
The following types of control
are performed based on data
such as road and traffic informa-
tion during route guidance by
the navigation system to help
ensure that the vehicle effi-
ciently uses electricity.

When there is a long downhill
slope along the route, the sys-
tem reduces the hybrid bat-
tery (traction battery) level
before reaching the slope to
help ensure charging capacity
for regenerative braking while
traveling downhill.
 When traffic congestion is
predicted along the route, the
system helps ensure a certain
battery level before reaching
congested roads to reduce
the frequency of starting the
engine to charge the hybrid
battery (traction battery) due
to low battery levels.

For safety and security
■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.444)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.3 gal.
[8.8 L, 1.9 Imp.gal.], when the vehi-
cle is on a level su rface. This value
may vary when the vehicle is on a
slope. Add extra fuel when the vehi-
cle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
Hybrid Electric Vehicles incorpo-
rate electromagnetic shielding,
and therefore emi t approximately
the same amount of electromag-
netic waves as conventional gaso-
line powered vehicles or home
electronic appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Hybrid battery (tr action battery)
The hybrid battery (traction battery)
has a limited service life. The lifes-
pan of the hybrid battery (traction
battery) can change in accordance
with driving style and driving condi-
tions.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C]) under
the influence of t he outside tem-
perature, it may no t be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increase etc.
WARNING
■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the warning labels
attached to the vehicle.
●Never try to open the service
plug access hole located under-
neath the rear seats. The ser-
vice plug is used only when the
vehicle is serviced and is sub-
ject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Pull your vehicle off the road,
shift the shift le ver to P, apply
the parking brake, and turn the
hybrid system off.
●Do not touch the high voltage
parts, cables and connectors.

761-4. Hybrid system
WARNING
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●Do not touch the battery if liquid
is leaking from or adhering to it.
If electrolyte (carbonic-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 bat-
tery) is damaged, the internal
construction of the battery will
prevent a large amount of elec-
trolyte from leaking out. How-
ever, any electrolyte that does
leak out will give off a vapor.
This vapor is an irritant to skin
and eyes and could cause acute
poisoning if inhaled.
●Do not bring burning or high-
temperature items close to the
electrolyte.
The electrolyte may ignite and
cause a fire.
●If a fire occurs in the Hybrid
Electric Vehicle, leave the vehi-
cle 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 four 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 l eaked onto the
ground, the fuel system may
have been damaged. Leave the
vehicle as soon as possible.
■Hybrid battery (traction bat-
tery)
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
●Your vehicle contains a sealed
lithium-ion battery.
Unless the battery is properly col-
lected, the following may occur,
resulting in dea th or serious
injury:
• The hybrid batte ry may be ille-
gally disposed of or dumped,
and it is hazardous to the envi-
ronment 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.

For safety and security
There is an air intake vent under
the right side of the rear seat for
the purpose of cooling the
hybrid battery (traction battery).
If the vent becomes blocked, the
hybrid battery (traction battery)
may overheat, leading to a
reduction in hybrid battery (trac-
tion battery) output.
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
without the hybrid battery hav-
ing 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 bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in death or serious
injury.

battery) air intake vent
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Make sure not to block the air
intake vent with anything, such
as a seat cover, plastic cover, or
luggage. The hybrid battery
(traction battery) may overheat
and be damaged.
●When dust etc. has accumu-
lated in the air intake vent, clean
it with a vacuum cleaner to pre-
vent the vent from clogging.
●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 bot-
tles 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.
●There is a filter installed to the
air intake vent. When the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. For
information regarding filter
cleaning or replacement, refer
to P.415.
●If “Maintenance Required for
Traction Battery Cooling Parts
See Owner’s Manual” is shown
on the multi-information dis-
play, the air intake vent and fil-
ter may be clogged. Refer to
P.415for information on how to
clean the air intake vent.

781-4. Hybrid system
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 mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played 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.
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
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.
