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.

Operation of each component
IS300h_EE(OM53B95E)
Conditions affecting operation
The smart entry & start system uses weak radio waves. In the following situa-
tions, the communication between the electronic key and the vehicle may be
affected, preventing the smart entry & start system, wireless remote control and
immobilizer system from operating properly. (Ways of coping: P. 548)
When the electronic key battery is depleted
Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility that generates strong radio waves or electrical noise
When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device
When the electronic key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
When other wireless keys (that emit radio waves) are being used nearby
When carrying the electronic key together with the following devices that emit
radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
If window tint with a metallic content or metallic objects are attached to the rear
window

1703-3. Adjusting the seats
IS300h_EE(OM53B95E)
The auto away/return function
enables easy access by activating
when the driver attempts to enter or
exit the vehicle.
Auto away function when exiting the vehicle
When all of the following actions have been performed, the steering
wheel will move up and back to the point farthest away from the driver
and the seat will move backward:
• The shift lever has been shifted to P.
• The power switch has been turned off.
• The driver’s seat belt has been unfastened.
Auto return function when entering the vehicle
When either of the following actions has been performed, the steering
wheel will move toward the driver and seat will move forward:
• The power switch has been turned to ACCESSORY mode.
• The driver’s seat belt has been fastened.

1723-3. Adjusting the seats
IS300h_EE(OM53B95E)
When driving position memory is linked with door unlock operation
If the driver’s door is opened, the driver’s seat will move toward the memorized
position but stop slightly beforehand to allow easy access to the vehicle.
Turning the power switch to ACCESSORY or ON mode, or fastening the
driver’s seat belt moves the seat fully into the memorized position.
Operating the driving position memory after turning the power switch off
Memorized seat positions can be activated up to 180 seconds after the driver’s
door is opened and another 60 seconds after it is closed again. Memorized steer-
ing wheel position can be activated by pressing the power switch.
Correct seat position
When the seat is in the most forward or most backward position, and the seat is
being moved in those directions, the system may not correctly recognize the cur-
rent position and the memorized position will not be correctly recalled.
The auto away function for exiting
If the seat is already close to the rearmost position, the auto away function may
not operate when the driver exits the vehicle.
When the driving position is recalled by a memory linked door unlock operation
Since each memorized driving position is registered to a specific electronic key,
the driving position recalled may be different depending on the carried key.
When only doors other than the driver’s door are unlocked by the smart entry &
start system, the driving position will not be recalled. In this case, press a driv-
ing position memory button to recall the desired driving position.
Customization
The distance that the driver’s seat moves backward during the auto away func-
tion can be changed. (Customizable features: P. 575)
CAUTION
Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passen-
ger or squeeze your body against the steering wheel.

so may result in death or serious injury.
Use the head restraints designed for each respective seat.
Adjust the head restraints to the correct position at all times.
After adjusting the head restraints, push down on them and make sure they are
locked in position.

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.
