IS300h_EE(OM53D89E)
■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 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 detection considerations
The sensor may trigger the alar m 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 auto matic 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 peop le outside the vehi-
cle
●Unstable items, such as dangling accessories
or clothes hanging on the coat hooks, are in the vehicle.

■Tilt sensor detection considerations
The sensor may trigger the alar m 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.

maneuvering into a garage is measured by the sensors and communicated via
the displays and a buzzer. Always chec k the surrounding area when using this
system.

WARNING
■When using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driven safely and possibly
cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●The sensors’ detection areas and reaction times are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially the sides of the vehi- cle) for safety, and drive slowly, using the brake to control the vehicle’s speed.
●Do not install accessories within the sensors’ detection areas.

WARNING
■Sensor detection information
●The sensor’ detection areas are limited to the areas around the vehicle’ bumper.
●Certain vehicle conditions and surrounding environments, such as the following, may
affect the ability of the sensor s to correctly detect objects. Pay particular attention in the following situations. Failure to do so may result in the vehicle being driven
unsafely, possibly leading to an accident.
• There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this prob- lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal dis- play, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to one side. • On an extremely bumpy road, on an incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other lo ud noises producing ultrasonic waves. • There is another vehicle equipped with parking assist sensors in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna. • Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb. • In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor. • A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there ar e instances in which, because of their shape, signs and other objects may be judged by a sensor to be closer than they are.
●The shape of the obstacle may prevent a sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects • Low obstacles
• Tall obstacles with upper sections projec ting outwards in the direction of your
vehicle • People, animals and other moving objects
• People wearing certain types of clothing
