WARNING
■People suffering illness
Obtain medical advice and wear the seat belt in the proper way. ( P. 38)
■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 othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, 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 any authorized Lexus retailer
or Lexus authorized repairer, or any reliable repairer.
■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 ne ck, 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. 39)
■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 re placed. 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 any authorized Lexus
retailer or Lexus authorized repa irer, or any reliable repairer.
●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 any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repa irer. Inappropriate handling may lead to
incorrect operation.

GS450h_300h_OM_OM30F92E_(EE) The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled by the airbag sensor assembly. As the airbags deploy, a chemi-
cal 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 driv er is very close to the airbag.
Since the risk zone for the driver’s airbag is the first 50 - 75 mm (2 - 3 in.) of inflation,
placing yourself 250 mm (10 in.) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center o f the steering wheel to
your breastbone. If you sit less than 250 mm (10 in.) away now, you can change your
driving position in several ways:

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 child 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 seats are safer for infants and children than the front
passenger seat. ( P. 57)
●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.

Safety information for children
●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 drivin g or operating the power window acci-
dentally. ( P. 143, 193)
● Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
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.
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 sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
(if equipped) or other features of the vehicle. In addition, heat build-up or extremely
cold temperatures inside the vehicle can be fatal to children.

WARNING
■Child restraint precautions
●For effective protection in automobile ac cidents 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 use a rear-facing child restraint syst em on the front passenger seat when the
airbag manual on-off switch is on. ( P. 54)
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child.
●A forward-facing child restraint system ma y be installed on the front passenger seat
only when it is unavoidable. A child restra int system that requires a top strap should
not be used in the front passenger seat sinc e there is no top strap anchor for the front
passenger seat. Adjust the seatback as up right as possible and always move the seat
as far back as possible because the front passenger airbag could inflate with consid-
erable speed and force. Otherwise, the ch ild may be killed or seriously injured.
●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 depl oy even if the child is seated in the child
restraint system. It is dangerous if the SR S 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 inju ry to the child in the event of a sudden
stop, sudden swerve or accident.
■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 othe r serious injuries that could result in death.
If this occurs and the buckle cannot be unfa stened, scissors should be used to cut the
belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child rest raint 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.
