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)

Maintenance and care
GS450h_300h_OM_OM30F92E_(EE) The meanings of each caution symbol on the top of the 12-volt battery are as fol-
lows:
■Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following precautions before recharging:
●If recharging with the 12-volt battery installed on the vehicle, be sure to disconnect the
ground cable.
●Make sure the power switch on the charger is off when connecting and disconnecting
the charger cables to the 12-volt battery.
■After recharging/reconnecting the 12-volt battery
●The hybrid system may not start. Follow the procedure below to initialize the system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
●Unlocking the doors using the smart entry & start system may not be possible immedi-
ately after reconnecting the 12-volt battery. If this happens, use the wireless remote
control or the mechanical key to lock/unlock the doors.
●Start the hybrid system with the power switch in ACCESSORY mode. The hybrid sys-
tem may not start with the power switch turned off. However, the hybrid system will
operate normally from the second attempt.
●The power switch mode is recorded by the vehicle. If the 12-volt battery is reconnected,
the vehicle will return the power switch mode to the status it was in before the 12-volt
battery was disconnected. Make sure to tu rn off the power switch before disconnect
the 12-volt battery. Take extra care when connecting the 12-volt battery if the power
switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts at all methods above, contact any
authorized Lexus retailer or Lexus author ized repairer, or any reliable repairer.

■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is off.
●Turn off any unnecessary electrical componen ts when the vehicle is running at a low
speed for an extended period, such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when the vehicle
is not in use, due to natural discharge and the draining effects of certain electrical appli-
ances. If the vehicle is left for a long time, the 12-volt battery may discharge, and the
hybrid system may be unable to start. (The 12-volt battery recharges automatically while
the hybrid system is operating.)
■When recharging or replacing the 12-volt battery
●In some cases, it may not be possible to unlock the doors using the smart entry & start
system when the 12-volt battery is discharged. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
●The hybrid system may not start on the first attempt after the 12-volt battery has
recharged but will start normally after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt battery is
reconnected, the system will return to the mode it was in before the 12-volt battery was
discharged. Before disconnecting the 12-v olt battery, turn the power switch off.
If you are unsure what mode the power switch was in before the 12-volt battery dis-
charged, be especially careful when reconnecting the 12-volt battery.
WARNING
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable gas
that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to come
into contact with any other parts or metal surfaces in the area, such as brackets or
unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with each
other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-volt
battery.
