The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
QWhen stopped/during start off
The gasoline engine stops
* when the
vehicle is stopped. During start off, the
electric motor (traction motor) drives
the vehicle. At slow speeds or when
traveling down a gentle slope, the
engine is stopped
* and the electric
motor (traction motor) is used.
When the shift lever is in N, the hybrid
battery (traction battery) is not being charged.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.
QDuring normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional 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 conditions, improving fuel efficiency and
reducing exhaust emissions.

601-4. Hybrid system
QWhen accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine via
the electric motor (traction motor).
QWhen braking (regenerative brak-
ing)
The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged.
QRegenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obtained in conjunction
with the recharging of the hybrid battery
(traction battery).
OThe accelerator pedal is released while
driving with the shift lever in D or S.
OThe brake pedal is depressed while driv-
ing with the shift lever in D or S.
QEV indicator
The EV indicator comes on when the vehi-
cle is driven using on ly the electric motor
(traction motor) or the gasoline engine is
stopped.
QConditions in which the gasoline engine
may not stop
The gasoline engine starts and stops auto-
matically. However, it may not stop auto-
matically in the following conditions
*:
ODuring gasoline engine warm-up
ODuring hybrid battery (traction battery) charging
OWhen the temperature of the hybrid bat-
tery (traction battery) is high or low
OWhen the heater is switched on
*: Depending on the circumstances, the
gasoline engine may also not stop auto-
matically in other situations.
QCharging the hybrid battery (traction
battery)
As the gasoline engine charges the hybrid
battery (traction battery), the battery does
not need to be charged from an outside
source. However, if the vehicle is left
parked for a long time the hybrid battery
(traction battery) will slowly discharge. For
this reason, be sure to drive the vehicle at
least once every few months for at least 30
minutes or 10 miles (16 km). If the hybrid
battery (traction battery) becomes fully dis-
charged and you are unable to start the
hybrid system, contact your Lexus dealer.
QCharging the 12-volt battery
 P.393
QAfter the 12-volt battery has discharged
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 your Lexus dealer.
QSounds and vibratio ns specific to a
hybrid vehicle
There may be no engine sound or vibration
even though the vehicle is able to move with
the “READY” indicator is illuminated. 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 operating
and are not a malfunction:
OMotor sounds may be heard from the
engine compartment.

soft clank will be emitted from the hybrid
battery (traction battery), under the rear
seats, when the hybrid system is started
or stopped.
OSounds from the hybrid system may be
heard when the trunk lid is open.
OSounds may be heard from the transmis-
sion when the gasoline engine starts or
stops, when driving at low speeds, or
during idling.
OEngine sounds may be heard when
accelerating sharply.
OSounds may be heard due to regenera-
tive braking when the brake pedal is
depressed or as the accelerator pedal is
released.
OVibration may be felt when the gasoline
engine starts or stops.
OCooling fan sounds may be heard from
the air intake vent under the rear seat.
QMaintenance, repair, recycling, and dis-
posal
Contact your Lexus dealer regarding main-
tenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
QCustomization
Settings (e.g. on/off operation of the EV
indicator) can be changed.
(Customizable features: P.421)
When driving with the gasoline engine
stopped, a sound, which changes in
accordance with the driving speed, will
be played in order to warn people
nearby of the vehicle’s approach. This
sound may be heard inside the vehicle.
The sound will stop when the vehicle
speed exceeds approximately 22 mph
(35 km/h).
QAcoustic Vehicle Alerting System
In the following cases, the Acoustic Vehicle
Alerting System may be difficult for sur-
rounding people to hear.

QRunning 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.367) 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 2.4 gal. [9.0 L, 2.0 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.)
QElectromagnetic waves
OHigh voltage parts and cables on hybrid
vehicles incorporate electromagnetic
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.

shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
OYour vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
QHybrid 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.
QStarting the hybrid system in an
extremely cold environment (for vehi-
cles sold in except Canada)
When the hybrid battery (traction battery)
is extremely cold (below approximately -
22°F [-30°C]) under the influence of the
outside temperature, it may not be possible
to start the hybrid system. In this case, try to
start the hybrid system again after the tem-
perature of the hybrid battery increases
due to the outside temperature increase
etc.
WARNING
QHigh 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 electric
shock that may result in death or serious
injury.
ONever touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
OThe 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.
ONever try to open the service plug
access hole located under the rear
seat (right side). The service plug is
used only when the vehicle is serviced
and is subject to high voltage.
QRoad accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
OPull your vehicle off the road, apply the
parking brake, shift the shift lever to P,
and turn the hybrid system off.
ODo not touch the high voltage parts,
cables and connectors.
OIf electric wires are exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed
electric wires.
OIf 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 danger-
ous.
OIf your vehicle needs to be towed, do
so with 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.361)
OCarefully inspect the ground under the
vehicle. If you find that liquid has
leaked onto the ground, the fuel sys-
tem may have been damaged. Leave
the vehicle as soon as possible.

641-4. Hybrid system
There is an air intake vent under the
rear seat (right side) for the purpose of
cooling the hybrid battery (traction
battery). If the vent becomes blocked,
WARNING
OFor vehicles sold in Canada: 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 pos-
sible, boric acid solution. Seek imme-
diate medical attention.
OFor vehicles sold in except Canada:
Do not touch the battery if liquid is
leaking from or adhering to it. If elec-
trolyte (carbonic-based organic elec-
trolyte) 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 con-
tact with the eyes or skin, wash it off
immediately with a large amount of
water, and seek immediate medical
attention.
OFor vehicles sold in except Canada: 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
damaged, the internal construction of
the battery will prevent a large amount
of electrolyte 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.
OFor vehicles sold in except Canada:
Do not bring burning or high-tem-
perature items close to the electrolyte.
The electrolyte may ignite and cause a
fire.
QHybrid battery (traction battery)
OFor vehicles sold in except Canada:
Your vehicle contains a sealed lithium-
ion battery.
ONever resell, hand over or modify the
hybrid battery. To prevent accidents,
hybrid batteries that have been
removed from a disposed vehicle are
collected through Lexus dealer. Do
not dispose of the battery yourself.
Unless the battery is properly col-
lected, the following may occur, result-
ing in death or serious injury:
• The hybrid battery may be illegally dis- posed of or dumped, and it is hazard-
ous to the environment or someone
may touch a high voltage part, result-
ing in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehi-
cle. 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.
OIf 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 Lexus
dealer or a qualified service shop. If the
hybrid battery is not disposed of prop-
erly, it may cause electric shock that
can result in death or serious injury.
