●A locked door is unlocked or opened in any way other than using the entry
function or wireless remote control. (The door will lock again automatically.)
●A trunk is opened in any way other than using the entry function, wireless
remote control or mechanical key.
●The hood is opened.
●The tilt sensor detects a change of vehicle inclination. (If equipped)
Close the doors, trunk and hood, and
lock all the doors using the entry func-
tion or wireless remote control. The

For safety and security
●The intrusion sensor detects intruders or movement in the vehicle.
●The tilt sensor detects changes in vehicle inclination, such as when the vehicle
is towed away.
This system is designed to deter and pr event vehicle theft but does not guarantee
absolute security against all intrusions.
■Setting the intrusion sensor and tilt sensor
The intrusion sensor and tilt sensor will be set automatically when the alarm is
set. ( →P. 9 2 )
■Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehicle, make sure to
stop the intrusion sensor and tilt sensor before setting the alarm, as they will
respond to movement inside the vehicle.
Turn the engine switch off.
Press the intrusion sensor and tilt
sensor cancel switch.
A message will be shown on the
multi-information display in the
instrument cluster.
Press the switch again to re-enable
the intrusion sensor and tilt sensor.

■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 engine switch or
unlocking the doors using the entry functi on, wireless remote control or mechanical
key 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 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) is
open.
In this case, the sensor may detect the follow-
ing:
• Wind or the movement of objects such asleaves and insects inside the vehicle
• Ultrasonic waves emitted from devices such as the intrusion sensors of other vehi-
cles
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in
the vehicle.

■Tilt sensor detection considerations (if equipped)
The sensor may trigger the alarm in the following situations:
●The vehicle is transported by a ferry, trailer, train, etc.
●The vehicle is parked in a parking garage.
●The vehicle is inside a car wash that moves the vehicle.
●Any of the tires loses air pressure.
●The vehicle is jacked up.
●An earthquake occurs or the road caves in.
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 detection performance.
●To ensure that the sensors operate properly,
do not touch or cover them.
●Do not spray air fresheners or other products
directly into the sensor holes.
