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)
WARNING
■Seat adjustment caution
Take care during seat adjustment so that the seat does not strike the rear passenger or
squeeze your body against the steering wheel.

Operation of each component
GS450h_300h_OM_OM30F92E_(EE)
■Setting automatic mode
Automatic mode allows the folding or extending of the mirrors to be linked to
locking/unlocking of the doors.
Press the “AUTO” switch to set auto-
matic mode.
The indicator will come on.
Pressing the switch once more will
return to manual mode.
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 neither
“L” nor “R”.
■Adjusting the mirror angle when the vehicle is reversing
With the shift lever in R, adjust the mirror angle at a desired positio n.
The adjusted angle will be memorized and the mirror will automatically tilt to
the memorized angle whenever the shift lever is shifted to R from next time. The memorized downward tilt position of the mirror is linked to the normal position
(angle adjusted with the shift lever in othe r than R). Therefore, if the normal posi-
tion is changed after adjustment, the tilt position will also change.
When the normal position is changed, readjust the angle in reversing.

■Mirror angle can be adjusted when
The power switch is in ACCESSORY or ON mode.
■When the mirrors are fogged up
The outside rear view mirrors can be clea red using the mirror defoggers. Turn on the
rear window defogger to turn on the outside rear view mirror defoggers. ( P. 352)
■Automatic adjustment of the mirror angle
A desired mirror face angle can be entered to memory and recalled automatically by the
driving position memory. ( P. 178)
■Auto anti-glare function
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. 188)
■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 event, remove any ice and snow
from the door mirror, then either operate the mirror using manual mode or move the mir- ror by hand.
WARNING
■Important points while driving
Observe the following precautions while driving.
Failure to do so may result in loss of control of the vehicle and cause an accident, result-
ing in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirrors must be extended and properly adjusted
before driving.
■When a mirror is moving
To avoid personal injury and mirror malfunction, be careful not to get your hand caught
by the moving mirror.
■When the mirror defoggers are operating
Do not touch the rear view mirror surfaces, as they can become very hot and burn you.

Driving
GS450h_300h_OM_OM30F92E_(EE)
■When starting off on a uphill
The hill-start assist control is available. ( P. 325)
■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary
to refrain from activities such as sudden acceleration, etc. Refer to “Hybrid vehicle driv-
ing tips”. ( P. 331)
■Driving in the rain
●Drive carefully when it is ra ining, because visibility will be reduced, the windows may
become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be especially slip-
pery.
●Refrain from high speeds when driving on an expressway in the rain, because there may
be a layer of water between the tires and the road surface, preventing the steering and
brakes from operating properly.
■Restraining hybrid system outp ut (Brake Override System)
●When the accelerator and brake pedals are depressed at the same time, the hybrid sys-
tem output may be restrained.
●A warning message is displayed on the mult i-information display while the system is
operating. ( P. 485)
■Restraining sudden start (Drive-Start Control)
●When the following unusual operation is pe rformed, the hybrid system output may be
restrained.

2044-1. Before driving
GS450h_300h_OM_OM30F92E_(EE)
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and reduce your
ability to control the vehicle.
●Sudden acceleration, engine braking due to shifting, or changes in engine speed
could cause the vehicle to skid, resulting in an accident.
●After driving through a puddle, lightly depress the brake pedal to make sure that the
brakes are functioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not functioning properly,
steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward while the shift lever is in a driving position, or roll
forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Do not shift the shift lever to a driving position while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle control.
●Shifting the shift lever to N while the vehicle is moving will disengage the hybrid sys-
tem. Engine braking is not available with the hybrid system disengaged.
●Be careful not to shift the shift lever with the accelerator pedal depressed. Shifting the
shift lever to any position other than P or N may lead to unexpected rapid accelera-
tion of the vehicle that may cause an accident and result in death or s erious injury.
■If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front and rear*
brakes: Moderate levels of brake pad and disc wear allow enhanced
braking power. As a result, the discs may wear more quickly than conventional brake
discs. Therefore, when replacing the brake pads, Lexus recommends that you also
have the thickness of the discs measured.
It is dangerous to drive the vehicle when th e wear limits of the brake pads and/or those
of the brake discs are exceeded.

Georgia
