●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 perfor-
mance.
●To ensure that the sensors operate prop-
erly, do not touch or cover them.
●Do not spray air fresheners or other prod-
ucts directly into the sensor holes.
