991-3. Theft deterrent system
1
For safety and security
IS300h_EE(OM53B95E)
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
canceled/set, a message will be
shown on the multi-information
display in the instrument cluster.

Tachometer
Hybrid System Indicator switches to the tachometer when driving mode is in
sport mode.
The settings of the tachometer display can be changed on the multi-information
display. (P. 1 1 9 )
Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help improve
fuel 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.)
Pop-up display
In some situations, such as when a switch operation is performed, a pop-up dis-
play, 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. 119)
Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is charac-
teristic of liquid crystal displays, and there is no problem continuing to use the
display.
Customization
The meter display can be customized on the multi-information display. (P.
116)
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.
The engine may be overheating if the engine coolant temperature gauge is in
the red zone (H). In this case, immediately stop the vehicle in a safe place, and
check the engine after it has cooled completely. (P. 555)

1823-4. Adjusting the steering wheel and mirrors
IS300h_EE(OM53B95E)
Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
Linked mirror function when reversing (if equipped)
When either “L” or “R” of the mirror select switch is selected, the outside rear
view mirrors will automatically angle downwards when the vehicle is reversing
in order to give a better view of the ground. To disable this function, select nei-
ther “L” nor “R”.
If the mirror angle adjustment switch is operated while the linked mirror func-
tion is in operation, the angle and position of the mirrors can be remembered,
and the mirrors will operate at the angle adjusted to the last time the linked mir-
ror function was operated.
However, because the mirrors move based on the angle they are in when the
linked mirror function is not operating, the mirror angle when the linked mirror
function is operating will also be changed if the mirrors are adjusted while the
function is not operating.
When the mirrors are fogged up
The outside rear view mirrors can be cleared using the mirror defoggers. Turn on
the rear window defogger to turn on the outside rear view mirror defoggers. (P.
404)
Automatic adjustment of the mirror angle (if equipped)
A desired mirror face angle can be entered to memory and recalled automatically
by the driving position memory. (P. 168)
Auto anti-glare function (if equipped)
When the anti-glare inside rear view mirror is set to automatic mode, the outside
rear view mirrors will activate in conjunction with the anti-glare inside rear view
mirror to reduce reflected light. (P. 179)
Using automatic mode in cold weather
When automatic mode is used in cold weather, the door mirror could freeze up
and automatic stowing and return may not be possible. In this case, remove any
ice and snow from the door mirror, then either operate the mirror using manual
mode or move the mirror by hand.
Customization
The automatic mirror folding and extending operation can be changed.
