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 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 betweenyou and the vehicle’s interior.
●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.
●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 instal lation instructions provided by the child restraint manufacturer and that the system is properly secured. If it is not securedproperly, 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 restraint 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.

For safety and security
■Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
●The alarm will still be set even when the intrusion sensor and tilt sensor are canceled.
●After the intrusion sensor and tilt sensor are canceled, pressing the power switch or unlocking the doors using the entry function, wireless remote control or mechanical
key will re-enable the intrusio n sensor and tilt sensor.
●The intrusion sensor and tilt sensor will automatically be re-enabled when the alarm system is deactivated.
■Intrusion sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
• The movement of people outside the vehicle
●Places with extreme vibrations or noises, or situations in which the vehicle is subject to
repeated impacts or vibrations:
• When parked in a parking garage • When the vehicle is transported by a ferry, trailer, train, etc.
• When ice adhering to the vehicle is removed • When the vehicle is in an automatic or high-pressure car wash• When in a hail or lightning storm
●A window or the moon roof (if equipped) isopen. In this case, the sensor may detect the follow-
ing:
• Wind or the movement of objects such as leaves and insects inside the vehicle
• Ultrasonic waves emitted from devices such as the intrusion sensors of other vehi-cles
●Unstable items, such as dangling accessoriesor clothes hanging on the coat hooks, are inthe vehicle.
