●Before scrapping your vehicle, make sure to contact any authorized Lexus retailer or
Lexus authorized repairer, or any reliable repairer.
●The Pop Up Hood system cannot be reused once it has operated. Have it replaced by
any authorized Lexus retailer or Lexus auth orized repairer, or any reliable repairer.
■Conditions under which the Pop Up Hood may not operate properly
The Pop Up Hood may not operate prop erly under the following conditions:
●If a pedestrian collides with the right or left corner of the front bumper or the side of the
vehicle. As such impacts may be difficult to detect, the system may not operate.
●If the vehicle speed is not detected correctly, such as if the vehicle is sliding sideways,
the system may not operate properly.
■Conditions under which the Pop Up Hood may not operate
The Pop Up Hood may not operate in the following situations:
●Colliding with a lying pedestrian
●A frontal impact applied to the front bumper while driving at speeds outside of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident si tuations, the Pop Up Hood may operate.)
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before driving, as the system may not operate properly if
the hood is not fully closed.
●Make sure that all 4 tires are of the specif ied size and inflated to the specified tire
pressure ( P. 652). If tires of a different size are used, the system may not operate
properly.
●If something has hit the area around the front bumper, the sensors may be damaged
even if the Pop Up Hood has not operated. Have the vehicle inspected by any autho-
rized Lexus retailer or Lexus authoriz ed repairer, or any reliable repairer.
●Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so may
cause accidental operation or prevent the sy stem from operating properly. If repair or
replacement is necessary, contact any auth orized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
●Do not remove such components as th e front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system from oper- ating properly.
●Do not install anything to the front bumper or hood, as doing so may prevent the sen-
sors from detecting an impact correctly an d prevent the system from operating prop- erly.
●Do not close the hood with force or apply load to the lifters, as doing so may damage
the lifters and prevent the system from operating properly.
●Do not modify the suspension, as changes made to the vehicle height may prevent
the system from op erating properly.

■When installing a child restraint system on the front passenger 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 sy stem, sit the child on a rear seat and use the
vehicle’s seat belt. ( P. 38)
When you have to use a child restraint system on the front passenger seat, adjust the following:
●The seatback to the most upright position
●The seat cushion to the highest position
●The seat cushion to the fully rearward position
WARNING
■Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly secure
the infant or child. It may result in death or serious injury (in the event of sudden braking or an accident).

661-1. For safe use
IS300h_EE(OM53D89E)
WARNING
■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, su dden swerve or 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 restra ined in the rear seat than in the front seat.
●Never use a rear-facing child restraint system on the front passenger seat when the
airbag manual on-off switch is on. ( P. 53)
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 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 po ssible because the front passenger airbag could inflate with considerable speed and fo rce. Otherwise, the child 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, center an d rear pillars or roof side rails from which
the SRS side airbags or SRS curtain shield ai rbags deploy even if the child is seated in
the child restraint system. It is dangerous if the SRS side airbags and curtain shield air- bags inflate, and the impact could caus e 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.
■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 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.
