Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics differ
ent
from conventional vehicles. Be sure you are closely familiar
with the characteristics of your vehicle, and operate it with
care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.

■If “Proximity Notification Sys-
tem Malfunction Visit Your
Dealer” is displayed on the
multi-information display
The system may be malfunctioning.
Have the vehicle inspected by your
Toyota dealer.
*: 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 support
Example: 7-inch display
Reference operation range
●When the vehicle approaches to
predictive deceleration support
points registered in the navigation
system, the “Reference operation
range” of the ECO Accelerator
Guidance ( P.104) on the
multi-information display will be
turned off to encourage the driver to reduce excessive acceleration.
●The engine braki
ng force will be
increased according to the driving
conditions to more efficiently
charge the hybrid battery (traction
battery) after the accelerator pedal
is released.
■Predictive SOC control
The following types of control are
performed based on data such as
road and traffic information during
route guidance by the navigation
system to help ensure that the vehi-
cle efficiently uses electricity.
●When there is a long downhill
slope along the r oute, the system
reduces the hybrid battery (trac-
tion battery) leve l before reaching
the slope to help ensure charging
capacity for regenerative braking
while traveling downhill.
●When traffic congestion is pre-
dicted along the route, the system
helps ensure a certain battery
level before reaching congested
roads to reduce the frequency of
starting the engin e to charge the
hybrid battery (traction battery)
due to low battery levels.

■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.463)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.9 gal.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 650 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

vehicle is on a level surface. This
value may vary whe
n 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 elec-
tromagnetic shielding, and there-
fore emit approximately the same
amount of electromagnetic waves
as conventional gasoline pow-
ered vehicles or home electronic
appliances.
●Your vehicle may cause sound
interference in some 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.

■High voltage precautions
This vehicle has high voltage DC
and AC systems as well as a
12-volt system. DC and AC high
voltage is very dangerous and
can cause severe burns and elec-
tric 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 sys tem 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
the rear seat. The service plug
is used only when the vehicle is
serviced and is subject 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.
●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 bat-
tery). 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 imme-
diate 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.

For safety and security
There are air intake vents under
each side of the rear seatback
for the purpose of cooling the
hybrid battery (traction battery).
If the vent is blocked,
charging/discharging of the
hybrid battery (traction battery)
may become limited.
WA R N I N G
●If your vehicle needs to be
towed, do so with all four
wheels raised. If the wheels
connected to the electric motor
(traction moto r) are on the
ground when towing, the motor
may continue to generate elec-
tricity. This may cause a fire.
(  P.455)
●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.
■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 your Toyota dealer. Do
not dispose of the battery your-
self.
Unless the battery is properly col-
lected, the following may occur,
resulting in dea th or serious
injury:
• The hybrid battery 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 vehicle. If the hybrid bat-
tery 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 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 dea th or serious
injury.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vents
Do not carry large amounts of
water such as water cooler bottles
in the vehicle. If water spills onto
the hybrid battery (traction bat-
tery), the battery may be dam-
aged. Have the vehicle inspected
by your Toyota dealer.

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. (
P.470)
■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.
NOTICE
■Hybrid battery (traction bat-
tery) air intake vent
●Do not place objects that will
block the air intake vents. The
hybrid battery (traction battery)
may become limited and be
damaged.
●Clean the air intake/discharge
vents regularly to prevent the
hybrid battery (traction battery)
to be limited.
●Do not allow liquid or foreign
material to enter 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. Wh en the filter
remains noticeably dirty even
after cleaning the air intake
vent, filter cleaning or replace-
ment is recommended. Refer to
