1-4.Hybrid system
The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
■When stopped/during start off
The gasoline engine stops
* when the
vehicle is stopped. During start off, the
electric motor (traction motor) drives
the vehicle. When the accelerator
pedal is only lightly depressed, such as
when traveling on a level surface or down a gentle slope, the engine is
stopped* and the electr
ic motor (trac-
tion motor) is used.
When the shift position is in N, the
hybrid battery (traction battery) is not
being charged.
Hybrid system features (LC500h)
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.
In addition to the conventional system, exclusive control is performed for four
driving conditions (starting off, acce lerating, low-speed driving and high-
speed cruising) to optimize the drive fo rce and fuel efficiency, allowing for a
more powerful drive and a higher fuel efficiency.

For safety and security
*: When the hybrid battery (traction bat-tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.
■During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
■When 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).
■When 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.
■Regenerative braking
In the following situations, kinetic energy is
converted to electric energy and decelera-
tion force can be obta ined in conjunction
with the recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released while
driving with the shift position in D or M.
●The brake pedal is depressed while driv-
ing with the shift position in D or M.
■EV indicator
The EV indicator comes on when the vehi-
cle is driven using only the electric motor
(traction motor) or th e gasoline engine is
stopped.
■Conditions 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
*:
●During gasoline engine warm-up
●During hybrid battery (traction battery)
charging
●When the temperature of the hybrid bat-
tery (traction battery) is high or low
●When the heater is switched on
●When the shift position is in M*: Depending on the circumstances, the gasoline engine may also not stop auto-
matically in other situations.
■Charging 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 rea-
son, be sure to drive the vehicle at least
once every few months for at least 30 min-
utes or 10 miles (16 km ). If the hybrid bat-
tery (traction battery) becomes fully
discharged and you are unable to start the
hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
 P.365
■After 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 bat-
tery (traction battery). If this continues for a
few days, contact your Lexus dealer.

621-4. Hybrid system
■Sounds and vibrations 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 position to P when
parked.
The following sounds or vibrations may
occur when the hybrid system is operating
and are not a malfunction:
●Motor sounds may be heard from the
engine compartment.
●Sounds may be heard from the hybrid
battery (traction battery) behind 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), behind the rear
seats, when the hybrid system is started
or stopped.
●Sounds from the hybrid system may be
heard when the trunk lid is open.
●Sounds may be heard from the transmis-
sion 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 regenera-
tive braking when the brake pedal is
depressed or as the accelerator pedal is
released.
●Vibration may be felt when the gasoline
engine starts or stops.
●Cooling fan sounds may be heard from
the air intake vents under the rear seats.
■Maintenance, repair, recycling, and dis-
posal
Contact your Lexus dealer regarding main-
tenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
■Customization
Settings (e.g. on/off operation of the EV
indicator) can be changed.
(Customizable features:  P.395)
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. The
sound will stop when the vehicle speed
exceeds approximately 22 mph (35
km/h).
■Vehicle proximity notification system
In the following cases, the vehicle proximity
notification system may be difficult for sur-
rounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification
system is installed on the front of the vehicle,
it may be more difficult to hear from the rear
of the vehicle compared to the front.
■If “Proximity Notification System Mal-
function Visit Your Dealer” is displayed
on the multi-information display
The system may be ma lfunctioning. Have
the vehicle inspected by your Lexus dealer.

shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
●Your vehicle may cause sound interfer-
ence 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.
■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 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
■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 electric
shock that may result in death or serious
injury.
●Never touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
●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 behind the rear
seats. The service pl ug 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 de ath or serious injury:
●Stop the vehicle in a safe place to pre-
vent subsequent accidents. While
depressing the brake pedal, apply the
parking brake and sh ift the shift posi-
tion to P to stop the hybrid system.
Then, slowly release the brake pedal.
●Do not touch the high voltage parts,
cables and connectors.
●If electric wires ar e exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed elec-
tric 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 con-
tact with the eyes or skin, wash it off
immediately with a large amount of
water, and seek immediate medical
attention.

661-4. Hybrid system
There are air intake vents under the
rear seats for the purpose of cooling
the hybrid battery (traction battery). If
the vents become blocked, the hybrid
battery input and output may be
restricted, leading to a reduction in
hybrid battery (traction battery) out-
put.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 electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact your Lexus dealer.
A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
message and follow the instructions.

tery) air intake vents
NOTICE
■Hybrid battery (traction battery) air
intake vents
●Make sure not to block the air intake
vent with anything, such as a seat
cover, plastic cover, or luggage. If the
vents become blocked, the hybrid bat-
tery (traction battery) input and output
may be restricted, leading to a reduc-
tion in hybrid battery (traction battery)
output and a malfunction.
●When dust etc. has accumulated in the
air intake vent, periodically clean it
with a vacuum cleaner to prevent the
vent from clogging.
●Filters are installed to the air intake
vent. When the filters remain notice-
ably dirty even after cleaning the air
intake vent, filter cleaning or replace-
ment is recommended. When clean-
ing or replacing the filters, contact
your Lexus dealer.
