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 atte ntion to driving. Anything that distracts the
driver, such as adjusting cont rols, talking on a cellular phone or reading can result in a
collision with resulting death or serious in jury to you, your occupants or others.
■General precaution regarding children’s safety
Never leave children unattended in the vehicl e, 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 tem- peratures inside the vehicle can be fatal to children.

WARNING
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can cause
death or serious injury especially if the fron t 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 infant s 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 chil d restraint system. Lexus strongly recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear se ats are safer for infants and children than the front passenger seat. ( P. 59)
●Do not sit on the edge of the seat or lean
against the dashboard.
●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.

WARNING
■SRS airbag precautions
●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 th e 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 allow anyone to kneel on the passen-
ger 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 and lower po rtion of the instru-
ment panel. These items can become projectiles when the
SRS driver, front passeng er and knee airbags
deploy.
●Do not attach anything to areas such as a door,
windshield glass, side d oor glass, front or rear pillar, roof side rail and assist grip. (Except for
the speed limit sticker P. 614)

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 part s immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SR S airbags have deployed, open a door or window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due 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 any
authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer.
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer. The SRS airbags ma y malfunction or deploy (inflate) accidentally, causing death or serious injury.
●Installation, removal, disassembl y 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
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios (RF-transmitter) and CD players
●Modifications to your ve hicle for a person with a physical disability

■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
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
front 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.
●Vehicles with ERA-GLONASS: If the SRS airbags deploy, the system is designed tosend an emergency call* to the Public Safety Answering Point (PSAP), 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 asce rtain 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. 496)
*: In some cases, the call cannot be made. (P. 498)
■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 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wa ll that does not move or deform).
However, this threshold veloci ty 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.
■SRS airbag deployment conditions (S RS 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 1500 kg [3300 lb.] vehicle colliding with the vehicle
cabin from a direction perpendicular to th e vehicle orientation at an approximate
speed of 20 - 30 km/h [12 - 18 mph]).
●The SRS curtain shield airbags will deploy in the event of a severe frontal collision.

■When to contact any authorized Lexus retailer or Lexus authorized repairer, or any
reliable repairer
In the following cases, the vehicle will require inspection and/or repair. Contact any
authorized Lexus retailer or Lexus authorized re pairer, or any reliable repairer as soon as
possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or deformed, or was involved in an accident that
was not severe enough to cause the SRS front
airbags to inflate.
●A portion of a door or its surrounding area is damaged or deformed, or the vehicle was
involved in an acciden t that was not severe
enough to cause the SRS side and curtain shield airbags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag or
lower portion of the instrument panel is scratched, cracked, or otherwise damaged.
●The surface of the seats with the side airbag is
scratched, cracked, or otherwise damaged.
●The portion of the front pillars, rear pillars or
roof side rail garnishes (padding) containing
the curtain shield airbags inside is scratched, cracked, or otherwise damaged.

581-1. For safe use
IS300h_EE(OM53D89E)
●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-pro tector lock or the window lock switch to avoid
children opening the door while drivin g or operating the power window acci-
dentally.
●Do not let small children operate equi pment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriat e for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
WARNING
Never leave children unattended in the vehicl e, 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 tempera-
tures inside the vehicle can be fatal to children.
