IS300h_EE(OM53B95E)
Trunk light (if equipped)
The trunk light turns on when the trunk is opened.
Function to prevent the trunk being locked with the electronic key inside
When all doors are locked, closing the trunk lid with the electronic key left
inside the trunk will sound an alarm.
In this case, the trunk lid can be opened pressing the trunk release button on the
trunk lid.
If the spare electronic key is put in the trunk with all the doors locked, the key
confinement prevention function is activated so the trunk can be opened. In
order to prevent theft, take all electronic keys with you when leaving the vehi-
cle.
If the electronic key is put in the trunk with all the doors locked, the key may
not be detected depending on the location of the key and the surrounding radio
wave conditions. In this case, the key confinement prevention function cannot
be activated, causing the doors to lock when the trunk is closed. Make sure to
check where the key is before closing the trunk.
The key confinement prevention function cannot be activated if any one of the
doors is unlocked. In this case, open the trunk using the trunk opener.
Using the mechanical key
The trunk can be also opened using the mechanical key. (P. 548)
If the smart entry & start system or the wireless remote control does not operate

IS300h_EE(OM53B95E)
CAUTION
Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the body to be caught, resulting in serious
injury.
Remove any heavy loads, such as snow and ice, from the trunk lid before
opening it. Failure to do so may cause the trunk lid to suddenly shut again
after it is opened.
When opening or closing the trunk lid, thoroughly check to make sure the sur-
rounding area is safe.
If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
Use caution when opening or closing the trunk lid in windy weather as it may
move abruptly in strong wind.
Do not attach any accessories other than genuine Lexus parts to the trunk lid.
Such additional weight on the trunk lid may cause the lid to suddenly shut
again after it is opened.
The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an incline
than on a level surface, so beware of the
trunk lid unexpectedly opening or closing
by itself. Make sure that the trunk lid is
fully open and secure before using the
trunk.
When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
When closing the trunk lid, make sure to
press it lightly on its outer surface. If the
trunk handle is used to fully close the
trunk lid, it may result in hands or arms
being caught.

Stop the vehicle on level ground, set the parking brake and shift the shift lever
to P.
Do not allow anyone to sit on a folded seatback or in the trunk while driving.

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.

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.

Operation of each component
IS300h_EE(OM53B95E)
The power windows can be operated when
The power switch is in ON mode.
Operating the power windows after turning the hybrid system off
The power windows can be operated for approximately 45 seconds after the
power switch is turned to ACCESSORY mode or turned off. They cannot, how-
ever, be operated once either front door is opened.
Jam protection function
If an object becomes caught between the window and the window frame, win-
dow travel is stopped and the window is opened slightly.
When the power window does not close normally
If the jam protection function is operating abnormally and a window cannot be
closed, perform the following operations using the power window switch on the
relevant door.
After stopping the vehicle, the window can be closed by holding the power
window switch in the one-touch closing position while the power switch is
turned to ON mode.
If the window still cannot be closed even by carrying out the operation as
explained above, initialize the function by performing the following procedure.
Hold the power window switch in the one-touch closing position. Continue
holding the switch for a further 6 seconds after the window has closed.
Hold the power window switch in the one-touch opening position. Continue
holding the switch for a further 2 seconds after the window has opened com-
pletely.
Hold the power window switch in the one-touch closing position once again.
Continue holding the switch for a further 2 seconds after the window has
closed.
If you release the switch while the window is moving, start again from the begin-
ning.
If the window continues to close but then re-open slightly even after performing
the above procedure correctly, have the vehicle inspected by any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
