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 engine
Approximately five hours after the engine 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.
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
● Lexus Safety 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.

Vehicle data recording
The vehicle is equipped with sophisticated computers that will record certain data, such
as:
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
•Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cameras. Contact your Lexus dealer for the location
of recording cameras.
The recorded data varies according to the vehicle grade level and options with which it is
equipped. These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
● Data Transmission
Your vehicle may transmit the data recorded in these computers to Lexus without notification to you.
● Data usage
Lexus may use the data recorded in this computer 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
● Recorded image information can be erased by your Lexus dealer.
The image recording function can be disabled. However, if the function is disabled,
data from when the system operates will not be available.
● To learn more about the vehicle data collected, used and shared by Lexus, please visit

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 non-trivial 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 information about the specific vehicle or vehicle owner

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.
WARNING
■ 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.

model year as your vehicle. Fix them securely in place onto the carpet.
Insert the retaining hooks (clips) into
the floor mat eyelets.
Turn the upper knob of each retaining hook (clip) to secure the floor

Check that the floor mat is securely fixed in
WARNING
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.
■ Before driving
●
the correct place with all the provided retaining hooks (clips). Be especially careful to perform this check after cleaning the floor.

1-1. For safe use
For safe driving
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. 143)
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. 143)
3
Lock the head restraint in place with the center of the head restraint closest to
the top of your ears. (P. 152)
4
Wear the seat belt correctly. (P. 30)
Correct use of the seat belts
Make sure that all occupants are wearing their seat belts before driving the vehicle. (P. 30)
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt. (P. 53)

1-1. For safe use
Adjusting the mirrors
Make sure that you can see backward clearly by adjusting the inside and outside
rear view mirrors properly. (P. 157, 159)
WARNING
29
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.
● Always observe the legal speed limit when driving on public roads.
● 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

does not come into contact with the
neck or slide off the shoulder.
● Position the lap belt as low as possi-
ble over the hips.
● Adjust the position of the seatback.
Sit up straight and well back in the
seat.
● Do not twist the seat belt.

Seat belt pretensioners (front seats and outboard rear seats)
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehicle is subjected to certain types of
severe frontal collision or a vehicle rollover.
The front seat belt pretensioners also
activate when the vehicle is subjected to
certain types of severe side collision.
The pretensioners do not activate in the event of a minor frontal impact, a minor side
impact or a rear impact.

■ After the rear center seat belt has been used
1-1. For safe use
Stow the buckle as shown.
■ 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 a child restraint system (CRS) firmly. To free the belt again, fully retract the belt and
then pull the belt out once more. (P. 57)
■ 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. 53)
● When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions regarding seat belt usage. (P. 30)
■ 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

WARNING
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.
■ Pregnant women
in the proper way. (P. 30)
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.

WARNING
■ People suffering illness
Obtain medical advice and wear the seat belt in the proper way. (P. 30)
■ 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
● Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the passenger’s weight properly. As a result, the seat belt pretensioner for the front passenger’s seat may not activate in the event of a collision.
● 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. 31)
■ 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.

WARNING
■ 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.
NOTICE
■ When using a seat belt extender
When releasing the seat belt, press on the buckle release button on the extender, not
on the seat belt.
This helps prevent damage to the vehicle interior and the extender itself.

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.

WARNING
■ 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 seri-
ous 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.

■ SRS airbag precautions
●
to the driver’s seat belt buckle but the seat
belt extender has not also been fastened to
the latch plate of the driver’s seat belt, the SRS
front airbags for the driver will judge that the
driver is wearing the seat belt even though the
seat belt has not been connected. In this case,
the SRS front airbags for the driver 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.
● 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 seriously
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. 53)

● 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 allow anyone to kneel on the passen-
ger seat 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 and lower portion of the instrument panel.
These items can become projectiles when the
SRS driver, front passenger and knee airbags
deploy.
● Do not attach anything to areas such as a
door, windshield glass, side door glass, front
or rear pillar, roof side rail and assist grip.
● Do not hang coat hangers or other 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 SRS 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.

WARNING
■ SRS airbag precautions
● Do not strike or apply significant levels of force to the area of the SRS airbag compo-
nents.
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 and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the passenger’s weight properly. As a result, the SRS front airbags for the front passenger
may not deploy in the event of a collision.
■ 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, 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, winches or
roof luggage carrier
● 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

extremely high speed deployment (inflation) by hot gases.
● 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, 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.
● All of the doors will be unlocked. (P. 129)
● Fuel supply to the engine will be stopped. (P. 524)
● For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
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. 68)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■ SRS airbag deployment conditions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
old 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 pretensioners will
activate.
● The SRS front airbags for the front passenger will not activate if there is no passenger
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. 46)
■ 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 approximate
spe ed of 12 - 18 mph [20 - 30 km/h]).
● Both SRS curtain shield airbags will deploy in the event of vehicle rollover.
● Both SRS curtain shield airbags will deploy in the event of a severe frontal collision.
IS350 AWD/IS350/IS300 AWD/IS300_U

1-1. For safe use
■ Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS curtain shield 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 sur-
face
● Falling into or jumping over a deep hole
● Landing hard or falling
The SRS curtain shield airbags may also deploy under the situations shown in the illustration.
● The angle of vehicle tip-up is marginal.
● The vehicle skids and hits a curb stone.
■ Types of collisions that may not deploy the SRS airbags (SRS front airbags)
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

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
The SRS side 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
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a rear
collision, if it pitches end over end, or if it is involved in a low-speed side or low-speed
frontal collision.
● Collision from the rear
● Pitching end over end

■ Front passenger occupant classification system precautions
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 front passenger may not
activate, 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. seatback
pocket).
● 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.

WARNING
■ Front passenger occupant classification system precautions
● Do not recline the front passenger seatback so far that it touches the rear seat. This
may cause the “AIR BAG OFF” indicator light to be illuminated, which indicates that
the SRS airbags for the front passenger 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 illumi-
nated. 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. 57)
● 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 front passenger
occupant classification 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 use a seat accessory, such as a cushion and seat cover, that covers the seat
cushion surface.
● Do not modify or replace the upholstery of the front seat.
● Do not place anything between the console box and front passenger seat. Other-
wise, the system may not detect the front passenger properly, leading to improper
operation of the airbags.
● Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.

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 con-
tact 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.
● Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
WARNING
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 appropriate 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. 57)

■ 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. This may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or an accident.
● 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, center 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 an accident.

WARNING
■ 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.
■ 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. This will prevent it from injuring passengers in the event
of a sudden stop, sudden swerve or accident.

WARNING
■ When installing a child restraint system
● When using the LATCH anchors for a child restraint system, move the seat as far
back as possible, with the seatback close to the child restraint system.
● When a booster seat is installed, always ensure that the shoulder belt is positioned
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 manufacturer.
● When securing some types of child restraint systems in rear seats, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without interfering with it or affecting seat belt effectiveness. Be sure your seat belt fits snugly
across your shoulder and low on your hips. If it does not, or if it interferes with the child
restraint, move to a different position. Failure to do so may result in death or serious
injury.
■ 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 a 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 a sudden braking, sudden swerve or an
accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
67
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
engine.
● Do not leave the vehicle with the engine 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 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 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.

■ Automatic Collision Notification
In case of either airbag deployment or severe rear-end collision, the system is
designed to automatically call the response center. The responding agent
receives the vehicle’s location and attempts to speak with the vehicle occupants to assess the level of emergency. If the occupants are unable to communicate, the agent automatically treats the call as an emergency, contacts the
nearest emergency services provider to describe the situation, and requests
that assistance be sent to the location.
■ Stolen Vehicle Location
If your vehicle is stolen, Safety Connect can work with local authorities to
assist them in locating and recovering the vehicle. After filing a police report,
call the Safety Connect response center at 1-800-25-LEXUS (1-800-255-

Safety information for Safety Connect
Important! Read this information before using Safety Connect.
■ Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power radio
transmitter and receiver. It receives and also sends out radio frequency (RF)
signals.
In August 1996, the Federal Communications Commission (FCC) adopted
RF exposure guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with the safety standards previously set by the following U.S. and international standards bodies.
● ANSI (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radiation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Protection)
[1996]
Those standards were based on comprehensive and periodic evaluations of
the relevant scientific literature. Over 120 scientists, engineers, and physicians from universities, and government health agencies and industries
reviewed the available body of research to develop the ANSI Standard
(C95.1).
The design of Safety Connect complies with the FCC guidelines in addition to
those standards.
