The Pop Up Hood will operate when the vehicle detects an impact such as the
following:
●The front bumper detects a frontal impact equivalent to or greater than that of
a pedestrian while the vehicle being driven within the operational speed range
of approximately 25 to 55 km/h (16 to 34 mph). (The system is operated by
an impact of threshold level or greater, even in the case of a minor collision
that may not leave a trace on the front bumper. Also, depending on the impact
conditions or vehicle speed, the system may be operated by a collision with a
light or small object or a small animal.)
●In other situations the system may operate when an impact is applied to the
lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding object or
falling object

WARNING
■When a child is riding
Observe the following precautions. Failure to do so may result in death or serious injury.
●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.
●Lexus strongly urges the use of a proper child restraint system that conforms to thesize 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.
●Holding a child in your or someone else’s ar ms is not a substitute for a child restraint system. In an accident, the child can be crushed against the windshield or betweenthe holder and the interior of the vehicle.
●Place one child to a child restraint system and then secure the child with the harnessof the child restraint system.
■Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers may be seriously injured or even killed in the event of sudden braking, sudden swerv- ing, or an accident.
●If the vehicle were to receive a strong impact from an accident, etc., it is possible thatthe child restraint system has damage that is not readily visible. In such cases, do notreuse the restraint system.
●Depending on the child restrain t system, installation may be difficult or impossible. In those cases, check whether the child restraint system is suitable for installment in the vehicle. ( P. 68, 75) Be sure to install and observe the usage rules after carefully
reading the child restraint system fixing me thod in this manual, as well as the opera- tion manual enclosed with the child restraint system.
●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.

WARNING
■When installing a child restraint system
●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 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 childrestraint system. It is dangerous if the SRS side and curtain shield airbags inflate, and
the impact could cause death or serious injury to the child.
