821-3. Theft deterrent system
GS450h_U (OM30D01U)
■System maintenance
The vehicle has a maintenance-free type alarm system.
■Items to check before locking the vehicle
To prevent unexpected triggering of the alarm and vehicle theft, make sure of the fol-
lowing:
●Nobody is in the vehicle.
●The windows and moon roof are closed before the alarm is set.
●No valuables or other personal items are left in the vehicle.
■Triggering of the alarm
The alarm may be triggered in the following situations:
(Stopping the alarm deactivates the alarm system.)
■Alarm-operated door lock
When the alarm is operating, the doors are locked automatically to prevent intrud-
ers.
●A person inside the vehicle opens a door,
the trunk or hood.
●The 12-volt battery is recharged or replaced
when the vehicle is locked. (→P. 7 7 2 )
NOTICE
■To ensure the system operates correctly
Do not modify or remove the system. If modified or removed, the proper operation
of the system cannot be guaranteed.

CAUTION
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal informa-
tion display. At extremely low temperatures, the information display monitor may
respond slowly, and display changes may be delayed.
For example, there is a lag between the driver’s shifting and the new gear number
appearing on the display. This lag could cause the driver to downshift again, caus-
ing rapid and excessive engine braking and possibly an accident resulting in death
or injury.
■Cautions during setting up the display
As the hybrid system needs to be operating during setting up the display, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed area such
as a garage, exhaust gases including harmful carbon monoxide (CO) may collect
and enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■During setting up the display
To prevent 12-volt battery discharge, ensure that the hybrid system is operating
while setting up the display features.

■Head-up display
●The head-up display may seem dark and hard to see when viewed through sun-
glasses, especially polarized sunglasses.
Adjust the brightness of the head-up display or remove your sunglasses.
●When the head-up display is turned off, it will remain off even if the power switch is
turned to ON mode after the power switch has been turned off.
■When the 12-volt battery is disconnected
The customize settings of the head-up display will be reset.
CAUTION
■Before using the head-up display
Check that the position and brightness of the head-up display image does not
interfere with safe driving. Incorrect adjustment of the image’s position or bright-
ness may obstruct the driver’s view and lead to an accident, resulting in death or
serious injury.
NOTICE
■To prevent damage to components
●Do not place any drinks near the head-up
display projector. If the projector gets wet,
electrical malfunctions may result.
●Do not place anything on or put stickers
onto the head-up display projector.
Doing so could interrupt head-up display
indications.
●Do not touch the inside of the head-up dis-
play projector or thrust sharp edges or the
like into the projector.
Doing so could cause mechanical malfunc-
tions.

Operation of each component
■Battery-saving function
The battery-saving function will be activated in order to prevent the electronic key
battery and the 12-volt battery from being discharged while the vehicle is not in
operation for a long time.
●In the following situations, the smart access system with push-button start may take
some time to unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of theoutside of the vehicle for 10 minutes or longer.
• The smart access system with push-button start has not been used for 5 days or longer.
●If the smart access system with push-button start has not been used for 14 days or
longer, the doors cannot be unlocked at any doors except the driver’s door. In this
case, take hold of the driver’s door handle, or use the wireless remote control or the
mechanical key, to unlock the doors.
■Electronic Key battery-Saving Function
When battery-saving mode is set, battery depletion is minimized by stopping the
electronic key from receiving radio waves.
Press twice while pressing and holding
. Confirm that the electronic key indi-
cator flashes 4 times.
While the battery-saving mode is set, the
smart access system with push-button start
cannot be used. To cancel the function, press
any of the electronic key buttons.

3-2. Opening, closing and locking the doors and trunk
CAUTION
■Trunk easy closer (vehicles with power trunk opener and closer)
■Power trunk opener and closer (if equipped)
Observe the following precautions when operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding area to make sure there are no obstacles or
anything that could cause any of your belongings to get caught.
●If anyone is in the vicinity, make sure they are safe and let them know that the
trunk is about to open or close.
●If the trunk closer switch is pressed while the trunk lid is opening during automatic
operation, the trunk lid stops opening. Take extra care when on an incline, as the
trunk lid may open or close suddenly.
●On an incline, the trunk lid may fall after it opens automatically. Make sure the
trunk lid is fully open and secure before using the trunk.
●In the following situations, the power trunk opener and closer may detect an
abnormality and automatic operation may be stopped. In this case, the trunk lid
has to be operated manually. Take extra care in this situation, as the stopped trunk
lid may suddenly fall, causing an accident.
• When the trunk lid contacts an obstacle
• When the 12-volt battery voltage suddenly drops, such as when the power switch is turned to ON mode or the hybrid system is started during automatic
operation
●Do not attach any accessories other than genuine Lexus parts to the trunk lid. The
power trunk opener and closer may not operate, causing itself to malfunction, or
the trunk lid may fall closed again after it is opened.
In the event that the trunk lid is left slightly
open, the trunk easy closer will automatically
close it to the fully closed position. It takes
several seconds before the trunk easy closer
begins to operate. Be careful not to catch fin-
gers or anything else in the trunk lid, as this
may cause bone fractures or other serious
injuries.

power switch will automatically turn off. However, this function cannot entirely pre-
vent 12-volt battery discharge. Do not le ave the vehicle with the power switch in
ACCESSORY or ON mode for long periods of time when the hybrid system is not
operating.

NOTICE
■To prevent 12-volt battery discharge
●Do not leave the power switch in ACCESSORY or ON mode for long periods of
time without the hybrid system on.
●If “POWER ON” is displayed on the multi-information display, the power switch
is not off. Exit the vehicle after turning the power switch off.

the hybrid system is stopped in another shift lever position, the power switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehicle is
left in ACCESSORY mode, 12-volt battery discharge may occur.
■Symptoms indicating a malfunction with the power switch
If the power switch seems to be operating somewhat differently than usual, such as
the switch sticking slightly, there may be a malfunction. Contact your Lexus dealer
immediately.
