1
For safety and security
IS300h_EE(OM53C61E)
●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 prevent 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 6 )
■Canceling the intrusion sensor and tilt sensor
If you are leaving pets or other moving things inside the vehicle, make sure to
disable the intrusion sensor and tilt sensor before setting the alarm, as they will
respond to movement inside the vehicle.
Turn the power switch off.
Press the intrusion sensor and tilt
sensor cancel switch.
Press the switch again to re-enable
the intrusion sensor and tilt sensor.
Each time the intrusion sensor is can-
celed/set, a message will be shown
on the multi-information display in
the instrument cluster.

efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even when vehicle
operation and driving conditions are the same.
■Outside temperature display
In the following situations, the correct outside temperature may not be displayed, or the
display may take longer than normal to change.
●When stopped, or driving at low speeds (less than 20 km/h [12 mph])
●When the outside temperature has changed suddenly (at the entrance/exit of a garage,
tunnel, etc.)
■Po p - u p d i s p l a y
In some situations, such as when a switch operation is performed, a pop-up display, such
as the operating methods of the headlight switch, will be temporarily displayed on the
multi-information display or the odometer/trip meter screen (F SPORT models only).
The pop-up display function can be set on/off. (→P. 1 1 8 )
■Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is characteristic
of liquid crystal displays, and there is no problem continuing to use the display.

NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which indicates
the maximum engine speed.

zone (H). In this case, immediately stop the vehicle in a safe place, and check the
engine after it has cooled completely. (→P. 552)
