●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 driving or operating the power window acci-
dentally.
●Do not let small children operate equipment 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 appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
CAUTION
Never leave children unattended in the vehicle, 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
or other features of the vehicle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

CAUTION
■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, sudden swerve or accident.
●Lexus strongly urges the use of a proper ch ild 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 th e 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. 5 4 )
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 may 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 possible 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 and 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 inju ry to the child in the event of a sudden
stop, sudden swerve or accident.

●Unlock the doors or open the trunk using the entry function or wireless
remote control.
●Start the hybrid system. (The alarm will be deactivated or stopped after a few

1001-3. Theft deterrent system
IS300h_EE(OM53D56E)
■Canceling and automatic re-enabling of the intrusion sensor and tilt sensor
●The alarm will still be set even when the intr usion 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 or wireless remote control will re-enable
the intrusion sensor and tilt sensor.
●The intrusion sensor and tilt sensor will au tomatically be re-enabled when the alarm
system is deactivated.
■Intrusion sensor dete ction considerations
The sensor may trigger the alarm in the following situations:
●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 on 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 is open.
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
• The movement of people outside the vehi-
cle
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in
the vehicle.
