Intrusion sensor (if equipped)
The sensor detects an intruder or movement in the vehicle. When
an intruder or movement is detected, the alarm will be triggered.
This system is designed to deter and prevent vehicle theft but does
not guarantee absolute security against all intrusions.
For details about the alarm, refer to “Alarm”.
Canceling the intrusion sensor (if equipped)
The operation of sensor can be canceled using the satellite
switches.

(P. 365)
System maintenance
The vehicle has a maintenance-free type alarm system.
Points to remember before locking the doors
To prevent unexpected triggering of the alarm, make sure to check the fol-
lowing before locking the doors:
Nobody is in the vehicle.
The windows and moon roof are closed before the alarm is set.
The alarm system does not guarantee absolute security. To help prevent
theft, make sure to check that no valuables and so forth are left in the vehi-
cle.

CAUTION
SRS airbag precautions
The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too
small to use a seat belt should be properly secured using a child restraint
system. Lexus strongly recommends that all infants and children be
placed in the rear seats of the vehicle and properly restrained. The rear
seats are the safest for infants and children. (P. 121)
Do not sit on the edge of the seat or
lean against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
Do not drive the vehicle while the
driver or passenger have items resting
on their knees.

IS250/220d/200d_EEIn this owner's manual, the following popular 3 types of child
restraint systems that can be secured with the seat belts are
explained.

When installing the child restraint system on the front passenger seat
Selecting an appropriate child restraint system
Get an appropriate child restraint system for the child. If a child is too large
for a child restraint system, sit the child on a rear seat and use the vehicle's
seat belt.
(P. 7 4 )
CAUTION
Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not prop-
erly secure the infant or child, resulting in serious injury or even death.
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 sud-
den stop or an accident.
Lexus strongly urges the use of a proper child restraint system that con-
forms to the size of the child, installed on the rear seat. According to acci-
dent statistics, the child is safer when properly restrained in the rear seat
than in the front seat.
When you have to use a child restraint
system in the front passenger seat, adjust
the seatback to the most upright position
and adjust the seat cushion to the upper-
most position.

CAUTION
Child restraint precautions
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 140)
In the event of an accident, the force of the rapid inflation of the front pas-
senger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front pas-
senger seat only when it is unavoidable. Always move the seat as far back
as possible, because the front passenger airbag could inflate with consid-
erable 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 pillar, rear pillar or roof side
rail from which the side airbags or curtain shield airbags deploy even if
the child is seated in the child restraint system. It is dangerous if the 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 an 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 other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used
to cut the belt.
When the child restraint system is not in use
Keep the child restraint system properly secured on the seat even if it is
not in use. Do not store the restraint unsecured in the passenger compart-
ment.
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.
