For your information
Main Owner’s Manual
Please note that this manual applies to all models and explains all equipment, including options. Therefore, you may find some explanations for equipment not installed
on your vehicle.
All specifications provided in this manual are current at the time of printing. However, because of the Lexus policy of continual product improvement, we reserve the
right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ from
your vehicle in terms of color and equipment.
Noise from under vehicle after turning off the hybrid system
Approximately five hours after the hybrid system is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and, it does not indicate a malfunction.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare parts and accessories for Lexus vehicles are
currently available in the market. You should know that Toyota does not warrant
these products and is not responsible for their performance, repair, or replacement,
or for any damage they may cause to, or adverse effect they may have on, your
Lexus vehicle.
This vehicle should not be modified with non-genuine Lexus products. Modification
with non-genuine Lexus products could affect its performance, safety or durability,
and may even violate governmental regulations. In addition, damage or performance problems resulting from the modification may not be covered under warranty.
GS450h_OM_OM30E26U_(U)
Installation of a mobile two-way radio system
The installation of a mobile two-way radio system in your vehicle could affect electronic systems such as:
● Multiport fuel injection system/sequential multiport fuel injection system
● Dynamic radar cruise control system
● Cruise control system
● Anti-lock brake system
● Vehicle dynamics integrated management
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Lexus dealer for precautionary measures or special
instructions regarding installation of a mobile two-way radio system.
High voltage parts and cables on the hybrid vehicles emit approximately the same
amount of electromagnetic waves as the conventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

Vehicle data recordings
Your Lexus is equipped with several sophisticated computers that will record certain
data, such as:
•Engine speed
• Electric motor speed (traction motor speed)
• Accelerator status
•Brake status
• Vehicle speed
• Shift position
• Hybrid battery (traction battery) status
The recorded data varies according to the vehicle grade level and options with
which it is equipped. Furthermore, these computers do not record conversations,
sounds or pictures.
● Data usage
Lexus may use the data recorded in these computers to diagnose malfunctions,
conduct research and development, and improve quality.
Lexus will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the
vehicle is leased
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
● Usage of data collected through Safety Connect / Lexus Enform (U.S. mainland
only)
If your Lexus has Safety Connect or Lexus Enform and if you have subscribed to
those services, please refer to the Safety Connect / Lexus Enform Telematics Subscription Service Agreement for information on data collected and its usage.
GS450h_OM_OM30E26U_(U)
Event data recorder
This vehicle is equipped with an event data recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near crash-like situations, such as an air bag
deployment or hitting a road obstacle, data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed to record data related to vehicle
dynamics and safety systems for a short period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were buckled/fastened;
• How far (if at all) the driver was depressing the accelerator and/or brake pedal;
and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR under normal driving conditions and no
personal data (e.g., name, gender, age, and crash location) are recorded. However,
other parties, such as law enforcement, could combine the EDR data with the type of
personally identifying data routinely acquired during a crash investigation.
To read data recorded by an EDR, special equipment is required, and access to the
vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties,
such as law enforcement, that have the special equipment, can read the information
if they have access to the vehicle or the EDR.
● Disclosure of the EDR data
Lexus will not disclose the data recorded in an EDR to a third party except when:
• An agreement from the vehicle’s owner (or the lessee for a leased vehicle) is
obtained
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes without disclosing infor-
mation about the specific vehicle or vehicle owner

CAUTION
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
■ General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that could result in death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the windows, the
moon roof, or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.

Floor mat
Use only floor mats designed specifically for vehicles of the same model
and model year as your vehicle. Fix them securely in place onto the carpet.
1
Insert the retaining hooks (clips)
into the floor mat eyelets.
2
Turn the upper knob of each
retaining hook (clip) to secure the
floor mats in place.
*: Always align the marks.
The shape of the retaining hooks (clips) may differ from that shown in the illustration.
GS450h_OM_OM30E26U_(U)
1-1. For safe use
CAUTION
● 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 hybrid system stopped and the
shift lever in P, fully depress each pedal to
the floor to make sure it does not interfere
with the floor mat.
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the
pedals while driving. An unexpectedly 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 Genuine floor mats.
● Only use floor mats designed for the driver’s seat.
● Always install the floor mat securely using the retaining hooks (clips) provided.
● 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.

For safety drive
For safe driving, adjust the seat and mirror to an appropriate position
before driving.
Correct driving posture
Adjust the angle of the seatback
so that you are sitting straight up
and so that you do not have to
lean forward to steer. (P. 150)
Adjust the seat so that you can
depress the pedals fully and so
that your arms bend slightly at the
elbow when gripping the steering
wheel. (P. 150)
Lock the head restraint in place

with the center of the head
restraint closest to the top of your
ears. (P. 15 8)
Wear the seat belt correctly.
4
(P. 32)
Correct use of the seat belts
Make sure that all occupants are wearing their seat belts before driving
the vehicle. (P. 32)
Use a child restraint system appropriate for the child until the child
becomes large enough to properly wear the vehicle’s seat belt. (P. 57)
GS450h_OM_OM30E26U_(U)
1-1. For safe use
CAUTION
Adjusting the mirrors
Make sure that you can see backward clearly by adjusting the inside and
outside rear view mirrors properly. (P. 162, 164)
Observe the following precautions.
Failure to do so may result in death or serious injury.
● Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
● Do not place a cushion between the driver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the
effectiveness of the seat belt and head restraint.
● Do not place anything under the front seats.
Objects placed under the front seats may become jammed in the seat tracks and
stop the seat from locking in place. This may lead to an accident and the adjustment mechanism may also be damaged.
● When driving over long distances, take regular breaks before you start to feel
tired.
Also, if you feel tired or sleepy while driving, do not force yourself to continue
driving and take a break immediately.

Seat belts
Make sure that all occupants are wearing their seat belts before driving
the vehicle.
Correct use of the seat belts
● Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with
the neck or slide off the shoulder.
● Position the lap belt as low as
possible over the hips.
● Adjust the position of the seat-
back. Sit up straight and well back
in the seat.
● Do not twist the seat belt.
Fastening and releasing the seat belt
To fasten the seat belt, push the
1
plate into the buckle until a click
sound is heard.
To release the seat belt, press the
2
release button.

Seat belt pretensioners (front and outboard rear seats)
The pretensioner helps the seat belt
to quickly restrain the occupant by
retracting the seat belt when the
vehicle is subjected to certain types
of severe frontal collision.
The front seat pretensioners also activate when the vehicle is subjected to
certain types of severe side collision.
The pretensioner does not activate in
the event of a minor frontal impact, a
minor side impact, a rear impact or a
vehicle rollover.
Pre-collision seat belts (front seats of vehicles with pre-collision
system)
If the pre-collision sensor detects that a collision is unavoidable, the precollision system will retract the seat belt before the collision occurs.
(P. 2 91 )
■ Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if
you lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
■ Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is used
to hold the child restraint system (CRS) firmly. To free the belt again, fully retract the
belt and then pull the belt out once more. (P. 61 )
GS450h_OM_OM30E26U_(U)
1-1. For safe use
CAUTION
■ Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
● Use a child restraint system appropriate for the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. (P. 5 7)
● When the child becomes large enough to properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt usage. (P. 3 2)
■ Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the
first collision, but will not activate for the second or subsequent collisions.
■ Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a personalized seat belt extender is available from
your Lexus dealer free of charge.

For safety and security
Observe the following precautions to reduce the risk of injury in the event of sudden
braking, sudden swerving or an accident.
Failure to do so may cause death or serious injury.
■ Wearing a seat belt
● Ensure that all passengers wear a seat belt.
● Always wear a seat belt properly.
● Each seat belt should be used by one person only. Do not use a seat belt for more
than one person at once, including children.
● Lexus recommends that children be seated in the rear seat and always use a seat
belt and/or an appropriate child restraint system.
● To achieve a proper seating position, do not recline the seat more than necessary.
The seat belt is most effective when the occupants are sitting up straight and well
back in the seats.
● Do not wear the shoulder belt under your arm.
● Always wear your seat belt low and snug across your hips.
GS450h_OM_OM30E26U_(U)
36
CAUTION
Obtain medical advice and wear the seat
belt in the proper way. (P. 32 )
Women who are pregnant should position
the lap belt as low as possible over the hips in
the same manner as other occupants,
extending the shoulder belt completely over
the shoulder and avoiding belt contact with
the rounding of the abdominal area.
If the seat belt is not worn properly, not only
the pregnant woman, but also the fetus could
suffer death or serious injury as a result of
sudden braking or a collision.
■ Pregnant women
■ People suffering illness
1-1. For safe use
Obtain medical advice and wear the seat belt in the proper way. (P. 3 2)
■ When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■ Seat belt pretensioners
If the pretensioner has activated, the SRS warning light will come on. In that case,
the seat belt cannot be used again and must be replaced at your Lexus dealer.
■ Adjustable shoulder anchor
Always make sure the shoulder belt is positioned across the center of your shoulder. The belt should be kept away from your neck, but not falling off your shoulder.
Failure to do so could reduce the amount of protection in an accident and cause
death or serious injuries in the event of a sudden stop, sudden swerve or accident.
(P. 3 3)

NOTICE
■ Seat belt damage and wear
● Do not damage the seat belts by allowing the belt, plate, or buckle to be jammed
in the door.
● Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from death or serious injury.
● Ensure that the belt and plate are locked and the belt is not twisted.
If the seat belt does not function correctly, immediately contact your Lexus
dealer.
● Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there is no obvious damage.
● Do not attempt to install, remove, modify, disassemble or dispose of the seat belts.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate handling may lead to incorrect operation.
■ Using a seat belt extender
● Do not wear the seat belt extender if you can fasten the seat belt without the
extender.
● Do not use the seat belt extender when installing a child restraint system because
the belt will not securely hold the child restraint system, increasing the risk of
death or serious injury in the event of an accident.
● The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.

CAUTION
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on the US motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU) controls airbag deployment based on information
obtained from the sensors etc. shown in the system components diagram
above. This information includes crash severity and occupant information.
As the airbags deploy, a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the motion of the occupants.
■ SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
● The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
● The SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250 mm) from your driver airbag provides you
with a clear margin of safety. This distance is measured from the center of the
steering wheel to your breastbone. If you sit less than 10 in. (250 mm) away now,
you can change your driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat.
Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm)
distance, even with the driver seat all the way forward, simply by reclining the
back of the seat somewhat. If reclining the back of your seat makes it hard to
see the road, raise yourself by using a firm, non-slippery cushion, or raise the
seat if your vehicle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA above, while still
maintaining control of the foot pedals, steering wheel, and your view of the
instrument panel controls.

CAUTION
● If the seat belt extender has been con-
nected to the front seat belt buckle but the
seat belt extender has not also been fastened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front airbags may not activate correctly in a collision, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.
● Do not sit on the edge of the seat or lean
against the dashboard.
■ SRS airbag precautions
1-1. For safe use
● The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
● Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are safer for infants and children than the
front passenger seat. (P. 57 )
GS450h_OM_OM30E26U_(U)
CAUTION
■ SRS airbag precautions
● Do not allow a child to stand in front of the
SRS front passenger airbag unit or sit on
the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do not lean against the door, the roof side
rail or the front, side and rear pillars.
● Do not allow anyone to kneel on the pas-
senger seats toward the door or put their
head or hands outside the vehicle.
● Do not attach anything to or lean anything
against areas such as the dashboard, steering wheel pad, lower portion of the instrument panel and door of the glove box.
These items can become projectiles when
the SRS driver, front passenger and knee
airbags deploy.

■ SRS airbag precautions
1-1. For safe use
● Do not hang coat hangers or hard objects on the coat hooks. All of these items
could become projectiles and may cause death or serious injury, should the SRS
curtain shield airbags deploy.
● If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it.
● Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags. Such accessories may
prevent the side airbags from activating correctly, disable the system or cause the
side airbags to inflate accidentally, resulting in death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS airbag
components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deployed, open a door
or window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off
any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel pad,
door of the glove box and front and rear pillar garnishes are damaged or cracked,
have them replaced by your Lexus dealer.
GS450h_OM_OM30E26U_(U)
1-1. For safe use
CAUTION
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without consulting your Lexus dealer. The SRS airbags may malfunction or deploy
(inflate) accidentally, causing death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, glove box, seats or seat upholstery, front, side and rear pillars
or roof side rails
● Repairs or modifications of the front fender, front bumper, or side of the occupant
compartment
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows or winches
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios and CD players
● Modifications to your vehicle for a person with a physical disability
■ If the SRS airbags deploy (inflate)
● Bruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as well as
the seats, the glove box, parts of the front and rear pillars, and roof side rails may be
hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● For Lexus Enform Safety Connect subscribers, if the SRS airbags deploy or in the
event of a severe rear-end collision, the system is designed to send an emergency
call to the response center, notifying them of the vehicle’s location (without needing
to push the “SOS” button) and an agent will attempt to speak with the occupants to
ascertain the level of emergency and assistance required. If the occupants are
unable to communicate, the agent automatically treats the call as an emergency
and helps to dispatch the necessary emergency services. (P. 4 00 )

■ SRS airbag deployment conditions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact that exceeds the set
1-1. For safe use
threshold level (the level of force corresponding to an approximately 12 - 18 mph
[20 - 30 km/h] frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
● Depending on the type of collision, it is possible that only the seat belt pretension-
ers will activate.
● The SRS front airbags for the front passenger will not activate if there is no passen-
ger sitting in the front passenger seat. However, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.
(P. 4 9)
■ SRS airbag deployment conditions (SRS side and curtain shield airbags)
● The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
app roximate speed of 12 - 18 mph [20 - 30 km/h]).
● The SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
sion.
■ Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
● Hitting a curb, edge of pavement or hard
surface
● Falling into or jumping over a deep hole
● Landing hard or falling
GS450h_OM_OM30E26U_(U)
1-1. For safe use
■ Types of collisions that may not deploy the SRS airbags (SRS front airbags)
47
The SRS front airbags do not generally inflate if the vehicle is involved in a side or
rear collision, if it rolls over, or if it is involved in a low-speed frontal collision. But,
whenever a collision of any type causes sufficient forward deceleration of the vehicle, deployment of the SRS front airbags may occur.
● Collision from the side
● Collision from the rear
● Vehicle rollover
■ Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield
airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to
a collision from the side at certain angles, or a collision to the side of the vehicle body
other than the passenger compartment.
● Collision from the side to the vehicle body
other than the passenger compartment
● Collision from the side at an angle
1
For safety and security
The SRS side and curtain shield airbags do not generally inflate if the vehicle is
involved in a frontal or rear collision, if it rolls over, or if it is involved in a low-speed
side collision.
● Collision from the front*
● Collision from the rear
● Vehicle rollover
*: Depending on the conditions and type of
accident, the curtain shield airbags may
deploy (inflate) upon frontal impact.

■ Front passenger occupant classification system precautions
1-1. For safe use
Observe the following precautions regarding the front passenger occupant classification system.
Failure to do so may cause death or serious injury.
● Wear the seat belt properly.
● Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.
● Make sure the “AIR BAG OFF” indicator light is not illuminated when using the
seat belt extender for the front passenger seat. If the “AIR BAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle, and
reconnect the seat belt. Reconnect the seat belt extender after making sure the
“AIR BAG ON” indicator light is illuminated. If you use the seat belt extender
while the “AIR BAG OFF” indicator light is illuminated, the SRS airbags for the
passenger may not activate correctly, which could cause death or serious injury
in the event of a collision.
● Do not apply a heavy load to the front passenger seat or equipment (e.g. seat-
back pockets or armrest).
● Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the rear passenger seat.
● Do not let a rear passenger lift the front passenger seat with their feet or press on
the seatback with their legs.
● Do not put objects under the front passenger seat.
GS450h_OM_OM30E26U_(U)
1-1. For safe use
CAUTION
■ Front passenger occupant classification system precautions
● Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear seat, return the seatback to a position where it does
not touch the rear seat. Keep the front passenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.
● If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn correctly. If the “AIR BAG OFF” indicator still remains illuminated, either ask the passenger to move to the rear seat, or if that is not possible, move the front passenger
seat fully rearward.
● When it is unavoidable to install a forward-facing child restraint system on the
front passenger seat, install the child restraint system on the front passenger seat
in the proper order. (P. 61 )
● Do not modify or remove the front seats.
● Do not kick the front passenger seat or subject it to severe impact. Otherwise,
the SRS warning light may come on to indicate a malfunction of the detection system. In this case, contact your Lexus dealer immediately.
● Child restraint systems installed on the rear seat should not contact the front seat-
backs.
● Do not modify or replace the upholstery of the front seat.

Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle’s seat belt.
● It is recommended that children sit in the rear seats to avoid accidental
contact with the shift lever, wiper switch etc.
● Use the rear door child-protector lock or the window lock switch to
avoid children opening the door while driving or operating the power
window accidentally. (P. 140, 167)
● Do not let small children operate equipment which may catch or pinch
body parts, such as the power window, hood, trunk, seats etc.
Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the windows, the
moon roof or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.

Child restraint systems
A child restraint system for a small child or baby must itself be properly
restrained on the seat with the LATCH anchors or the lap portion of the
lap/shoulder belt.
The laws of all 50 states of the U.S.A. and Canada now require the use
of child restraint systems.
Points to remember
Studies have shown that installing a child restraint on a rear seat is much
safer than installing one on the front passenger seat.
● Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
● For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (P. 61)

Forward facing Convertible
seat
■ Selecting an appropriate child restraint system
● Use a child restraint system appropriate for the child until the child becomes large
enough to properly wear the vehicle’s seat belt.
● If the child is too large for a child restraint system, sit the child on a rear seat and use
the vehicle’s seat belt. (P. 32)
GS450h_OM_OM30E26U_(U)

CAUTION
■ Child restraint precautions
● For effective protection in automobile accidents and sudden stops, a child must
be properly restrained, using a seat belt or child restraint system depending on
the age and size of the child. Holding a child in your arms is not a substitute for a
child restraint system. In an accident, the child can be crushed against the windshield, or between you and the vehicle’s interior.
● Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed on the rear seat. According to accident statistics, the
child is safer when properly restrained in the rear seat than in the front seat.
● Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illuminated.
In the event of an accident, the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child if the rear-facing child
restraint system is installed on the front passenger seat.
● A forward-facing child restraint system may be installed on the front passenger
seat only when it is unavoidable. A child restraint system that requires a top tether
strap should not be used in the front passenger seat since there is no top tether
strap anchor for the front passenger seat. Adjust the seatback as upright as possible and always move the seat as far back as possible even if the “AIR BAG OFF”
indicator light is illuminated, because the front passenger airbag could inflate with
considerable speed and force. Otherwise, the child may be killed or seriously
injured.
● Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of a sudden stop, sudden swerve or accident.
● Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front and rear pillars or roof side rails from which the
SRS side airbags or SRS curtain shield airbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield
airbags inflate, and the impact could cause death or serious injury to the child.
● Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the system is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop, sudden swerve or accident.

If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■ When the child restraint system is not in use
● Keep the child restraint system properly secured on the seat even if it is not in use.
Do not store the child restraint system unsecured in the passenger compartment.
● If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the trunk. If a head restraint was removed when installing a
child restraint system, always install the head restraint before driving. This will prevent it from injuring passengers in the event of a sudden stop, sudden swerve or
accident.

CAUTION
■ When installing a child restraint system
1-1. For safe use
● When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from
the child’s neck, but not so that it could fall off the child’s shoulder. Failing to do so
may result in death or serious injury in the event of sudden braking, sudden
swerving or an accident.
● Ensure that the belt and plate are securely locked and the seat belt is not twisted.
● Shake the child restraint system left and right, and forward and backward to
ensure that it has been securely installed.
● After securing a child restraint system, never adjust the seat.
● Follow all installation instructions provided by the child restraint system manufac-
turer.
■ Do not use a seat belt extender
If a seat belt extender is used when installing a child restraint system, the seat belt
will not securely hold the child restraint system, which could cause death or serious
injury to the child or other passengers in the event of sudden braking, sudden
swerving or an accident.
■ To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not caught behind the child restraint system.
Make sure the child restraint system is securely attached, or it may cause death or
serious injury to the child or other passengers in the event of sudden braking, sudden swerving or an accident.

Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless. Observe the following precautions.
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 vehicle even when the trunk lid is closed, open
the windows and have the vehicle 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 hybrid system.
● Do not leave the vehicle with the hybrid system on 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 hybrid system operating in an area with snow build-up, or where
it is snowing. If snowbanks build up around the vehicle while the hybrid system is
operating, exhaust gases may collect and enter the vehicle.
■ 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.

1-2. Hybrid system
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics different from
conventional vehicles. Be sure you are closely familiar with the characteristics of your vehicle, and operate 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.
Gasoline engine
1
Electric motor (traction motor)
2
GS450h_OM_OM30E26U_(U)
1-2. Hybrid system
◆ 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. At slow speeds or
when traveling down a gentle slope, the engine is stopped and the electric motor (traction motor) is used.
◆ 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 braking)
The electric motor (traction motor) charges the hybrid battery (traction
battery).
73

For safety and security
Vehicle proximity notification system
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 15 mph (25 km/h).
GS450h_OM_OM30E26U_(U)
74
■ Regenerative braking
1-2. Hybrid system
In the following situations, kinetic energy is converted to electric energy and deceleration force can be obtained 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 S.
● The brake pedal is depressed while driving with the shift position in D or S.
■ EV indicator
The EV indicator comes on when the vehicle
is driven using only the electric motor (traction motor) or the gasoline engine is stopped.
■ Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automatically in the following conditions:
● During gasoline engine warm-up
● During hybrid battery (traction battery) charging
● When the temperature of the hybrid battery (traction battery) is high or low
● When the heater is switched on
■ 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 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 becomes fully discharged and you are unable
to jump-start the vehicle with the 12-volt battery, contact your Lexus dealer.
● If the shift lever is in N, the hybrid battery (traction battery) will not be charged.
Always put the shift lever in P when the vehicle is stopped. When driving in heavy
traffic, operate the vehicle with the shift lever in D or S to avoid discharging the battery.
■ Charging the 12-volt battery
P. 5 63
GS450h_OM_OM30E26U_(U)
1-2. Hybrid system
■ After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
■ Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move.
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.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the hybrid transmission when the hybrid system starts
or stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents on the both sides of the
rear seatback.
■ Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be difficult for
surrounding 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.
■ Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding maintenance, 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.

Hybrid battery (traction battery) air vents
There are air intake vents on the
both sides of the rear seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vents become blocked, the hybrid
battery may overheat, leading to a
reduction in hybrid battery output.
Emergency shut off system
When a certain level of impact is detected by the impact sensor, the emergency shut off system blocks off the high voltage current and stops the fuel
pump to minimize the risk of electrocution and fuel leakage. If the emergency shut off system activates, your vehicle will not restart. To restart the
hybrid system, contact your Lexus dealer.
Hybrid warning message
77
1
For safety and security
A message is automatically displayed 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 instruc-
(P. 513)
tions.
GS450h_OM_OM30E26U_(U)

■ If a warning light comes on, a warning message is displayed, or the 12-volt battery is
1-2. Hybrid system
disconnected
The hybrid system may not start. In that case, try to start the system again. If the
“READY” indicator does not come on, contact your Lexus dealer.
■ Running 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. 506, 528) go off. If there is only a small amount of fuel, the hybrid system may
not be able to start. (The minimum amount of fuel to add to make the low fuel level
warning light go out is about 2.6 gal. [10.0 L, 2.2 Imp.gal.], when the vehicle is on a
level surface. This value may vary when the vehicle is on a slope.)
■ Electromagnetic waves
● High voltage parts and cables on the hybrid vehicles incorporate electromagnetic
shielding, and therefore emit approximately the same amount of electromagnetic
waves as conventional gasoline powered vehicles or home electronic appliances.
● Your vehicle may cause sound interference 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.
GS450h_OM_OM30E26U_(U)
1-2. Hybrid system
CAUTION
● Never try to open the service plug access
hole located behind the rear seats. The service plug is used only when the vehicle is
serviced and is subject to high voltage.
■ High voltage precautions
The 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 caution labels attached to the vehicle.
■ Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, 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 battery). 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 immediate 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.
● If your vehicle needs to be towed, do so with rear 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 an electricity
leakage leading to a fire. (P. 4 96 )
● 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.

NOTICE
■ Hybrid battery (traction battery)
1-2. Hybrid system
● Your vehicle contains a sealed nickel-metal hydride battery. Never 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 collected, the following may occur, resulting in
death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is hazardous
to the environment 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 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.
● If 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 properly, it may cause electric shock
that can result in death or serious injury.
■ Hybrid battery air vents
● Do not put foreign objects near the air vents. The hybrid battery (traction battery)
may overheat and be damaged.
● Clean the air vents regularly to prevent the hybrid battery (traction battery) from
overheating.
● Do not wet or allow foreign substances to enter the air vents 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 bottles in the vehicle. If
water spills onto the hybrid battery (traction battery), the battery may be damaged. Have the vehicle inspected by your Lexus dealer.

nate in the following situations:
• When the power switch is turned to ON mode while the BSM main switch is set
to ON.
• When the BSM main switch is set to ON while the power switch is in ON mode.
If the system is functioning correctly, the BSM outside rear view mirror indicators
will turn off after a few seconds.
If the BSM outside rear view mirror indicators do not illuminate or do not turn off,
there may be a malfunction with the system.
If this occurs, have the vehicle inspected by your Lexus dealer.
■ If a safety system warning light does not come on
Should a safety system light such as the ABS and SRS warning light not come on
when you start the hybrid system, this could mean that these systems are not available to help protect you in an accident, which could result in death or serious injury.
Have the vehicle inspected by your Lexus dealer immediately if this occurs.
