Observe the following before start-
ing off in the vehicle to ensure
safety of driving.
Installing floor mats
A
WARNING
Observe the following precautions.
Failure to do so may cause the driver’s
floor mat to slip, poss ibly interfering with
the pedals while driv ing. An unexpect-
edly high speed may result or it may
become difficult to stop the vehicle. This
could lead to an accident, resulting in
death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for
other models or different model year
vehicles, even if they are Lexus Genu-
ine floor mats.
●Only use floor mats designed for the
driver’s seat.
●Always install the floor mat securely
using the retaining hooks (clips) pro-
vided.
●Do not use two or more floor mats on
top of each other.
●Do not place the floor mat bottom-
side up or upside-down.
■Before driving
●Check that the floor mat is securely
fixed in the correct place with all the
provided retaining hooks (clips). Be
especially careful to perform this
check after cleaning the floor.
●With the engine
stopped and the shift position in P, fully
depress each pedal to the floor to

■Pop Up Hood precautions
●Before scrapping your vehicle, make sure
to contact your Lexus dealer.
●The Pop Up Hood system cannot be
reused once it has operated. Have it
replaced by your Lexus dealer.
■Pop Up Hood operational conditions
The Pop Up Hood will operate when the
vehicle detects an impact such as the fol-
lowing:
●The front bumper detects a frontal impact
equivalent to or grea ter than that of a
pedestrian while the vehicle being driven
within the operational speed range of
approximately 16 to 34 mph (25 to 55
km/h). (The system is operated by an
impact of threshold level or greater, even
in the case of a minor collision that may
not leave a trace on the front bumper.
Also, depending on the impact condi-
tions or vehicle speed, the system may
operate by a collision with a light or small
object or a small animal.)
●In other situations such as the following,
the system may operate when an impact
is applied to the lower part of the vehicle
or front bumper:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a pr otruding object or
falling object
■Conditions under which the Pop Up
Hood may not operate properly
●If a pedestrian collides with the right or
left corner of the front bumper or the side
of the vehicle. As such impacts may be
difficult to detect, the system may not
operate.
●If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate
properly.
■Conditions under which the Pop Up
Hood will not operate
The Pop Up Hood will not operate in the
following situations:
●Colliding with a lying person
●A frontal impact applied to the front
bumper while driving at speeds outside
of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situ-
ations, the Pop Up Hood may operate.)
Pop Up Hood
In the event of a frontal collision
with a body, such as a pedestrian,
the Pop Up Hood system raises the
hood to reduce the possibility of a
serious impact to the pedestrian’s
head area by adding clearance to
the engine compartment.
When the sensors located at the
back of the front bumper detect a
frontal impact with a body, such as a
pedestrian, which meets or
exceeds the threshold level while
the vehicle is being driven within
the operational speed range, the
system operates.

Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
■When parking
●If the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the engine tem>.
●Do not leave the vehicle with the
engine running ing> for a long time.
If such a situation cannot be avoided,
park the vehicle in an open space and
ensure that exhaust fumes do not enter
the vehicle interior.
●Do not leave the engine running
in an area
with snow build-up, or where it is
snowing. If snowbanks build up around
the vehicle while the engine is running
, exhaust
gases may collect and enter the vehi-
cle.
■Exhaust pipe
The exhaust system needs to be checked
periodically. If there is a hole or crack
caused by corrosion, damage to a joint
or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired
by your Lexus dealer.

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.
