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 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 is open.
In this case, the sensor may detect the
following:
• 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 acces-
sories or clothes hanging on the coat
hooks, are in the vehicle.

NOTICE
To ensure the intrusion sensor function correctly
Installing accessories other than genuine Lexus parts or leaving objects
between the driver’s seat and front passenger’s seat may reduce the detec-
tion performance.
To ensure that the sensors operate prop-
erly, do not touch or cover them.
Do not spray air fresheners or other
products directly into the sensor holes.
