It is recommended that children sit in the rear seats to avoid accidental
contact 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 accidentally.
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 shift the vehicle into neutral. There
is also a danger that children may injure themselves by playing with the win-
dows, the moon roof or other features of the vehicle. In addition, heat build-up
or extremely cold temperatures 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 depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute 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 child restraint system that conforms
to the size of the child, installed on the rear seat. According to accident statis-
tics, the child is safer when properly restrained 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. 5 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front passen-
ger seat only when it is unavoidable. A child restraint 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 force.
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 airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the SRS 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 injury to the child in the
event of a sudden stop, sudden swerve or accident.

Do one of the following to deactivate or stop the alarm:
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

Items to check before locking the vehicle

following:
Nobody is in the vehicle.
The windows and moon roof (if equipped) are closed before the alarm is set.

Deactivating or stopping the alarm

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 can-
celed.
After the intrusion sensor and tilt sensor are canceled, pressing the power
switch or unlocking the doors using the entry function or wireless remote con-
trol will re-enable the intrusion 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
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 fol-
lowing:
• 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
vehicles
• The movement of people outside the
vehicle
Unstable items, such as dangling accesso-
ries or clothes hanging on the coat hooks,
are in the vehicle.
