WARNING
■When installing a child restraint system
For safety reasons, always install a child rest raint system in a rear seat. In the event that
the rear seat cannot be used, the front seat can be used as long as the airbag manual
on-off system is set to off.
If the airbag manual on-off system is left on, the strong impact of the airbag deployment
(inflation) may cause serious injury or even death.
■When a child restraint system is not installed on the front passenger seat
Ensure that the airbag manual on-off system is set to on.
If it is left off, the airbag may not deploy in the event of an accident, which may result in
serious injury or even death.

For safety and security
Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open the
windows and have the vehicle inspected at any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer as soon as possible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
hybrid system.
●Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure
that exhaust fumes do not enter the vehicle interior.
●Do not leave the hybrid system operating in an area with snow build-up, or where it is
snowing. If snowbanks build up around the vehicle while the hybrid system is operat-
ing, exhaust gases may collect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole or crack caused
by corrosion, damage to a joint or abnormal exhaust noise, be sur e to have the vehicle
inspected and repaired by any authorized Le xus retailer or Lexus authorized repairer,
or any reliable repairer.

821-2. Hybrid system
GS450h_300h_OM_OM30F92E_(EE)
■If a warning light comes on, a warning message is displayed, or the 12-volt battery is dis-
connected
The hybrid system may not start. In this case, try to start the system again. If the “READY”
indicator does not come on, contact any authorized Lexus retailer or Lexus authorized
repairer, or any reliable repairer.
■Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light ( P. 462)
go off. If there is only a small amount of fuel, the hybrid sys tem may not be able to start.
(The standard amount of fuel is about 9.9 L [2 .6 gal., 2.2 Imp.gal.], when the vehicle is on
a level surface. This value may vary when the vehicle is on a slope. Add extra fuel when
the vehicle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on hybrid ve hicles incorporate electromagnetic shield-
ing, and therefore emit approximately the same amount of electromagnetic waves as
conventional gasoline powered vehicles or home electronic appliances.
●Your vehicle may cause sound interference in some third party-produced radio parts.
■Hybrid battery (traction battery)
The hybrid battery (traction battery) has a lim ited service life. The lifespan of the hybrid
battery (traction battery) can change in accordance with driving style and driving condi-
tions.
■Declaration of conformity
This model conforms to hydrogen emissions according to regulation ECE100 (Battery
electric vehicle safety).
WARNING
■High voltage precautions
This vehicle has high voltage DC and AC systems as well as a 12-volt system. DC and
AC high voltage is very dangerous and can cause severe burns and electric shock that
may result in death or serious injury.
●Never touch, disassemble, remove or replace the high voltage parts, cables or their
connectors.
●The hybrid system will become hot after starting as the system uses high voltage. Be
careful of both the high voltage and the hi gh temperature, and always obey the warn-
ing labels attached to the vehicle.
●Never try to open the service plug access
hole located behind the rear seats. The ser-
vice plug is used only when the vehicle is ser-
viced and is subject to high voltage.

1503-2. Opening, closing and locking the doors and trunk
GS450h_300h_OM_OM30F92E_(EE)
WARNING
■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, thor oughly check to make sure the surround-
ing 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 tr unk 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 unexpect-
edly opening or closin g 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
grip is used to fully close the trunk lid, it may
result in hands or arms being caught.

GS450h_300h_OM_OM30F92E_(EE)
■Recall procedure
Carry the electronic key that has been registered to the driving position,
and then unlock and open the driver’s door using the smart entry & start
system or wireless remote control.
The driving position will move to the reco rded position (not including the steering
wheel and HUD [head-up display] [if equipp ed]). However, the seat will move to a
position slightly behind the recorded position in order to make entering the vehicle
easier.
If the driving position is in a position that has already been recorded, the seat and
outside rear view mirrors will not move.
Turn the power switch to ACCESSORY mode or ON mode, or fasten a
seat belt.
The seat, steering wheel and HUD (head-up display) (if equipped) will move to the
recorded position.
■Cancelation procedure
Carry only the key you want to cancel and then close the driver’s door.
If 2 or more keys are in the vehicle, the driving position cannot be canceled
properly.
Turn the power switch to ON mode.
While pressing the “SET” button, press and hold the door lock switch
(either lock or unlock) until the buzzer sounds twice.
If the button could not be canceled, the buzzer sounds continuously for approxi- mately 3 seconds.
■Recalling the driving position us ing the memory recall function
●Different driving positions can be registered for each electronic key. Therefore, the
driving position that is recalled may be different depending on the key being carried.
●If a door other than the driver’s door is unlocked with the smart entry & start system, the
driving position cannot be recalled. In this case, press the driving position button which
has been set.
■Customization
The unlock door settings of the memory recall function can be customized.
(Customizable features: P. 561)
