Jam protection function
If an object becomes caught between the window and the window frame,
window 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 proce-
dure.
Hold the power window switch in the one-touch closing position. Con-
tinue holding the switch for a further 6 seconds after the window has
closed.
Hold the power window switch in the one-touch opening position. Con-
tinue holding the switch for a further 2 seconds after the window has
opened completely.
Hold the power window switch in the one-touch closing position once
again. Continue holding the switch for a further 2 seconds after the win-
dow has closed.
If you release the switch while the window is moving, start again from the
beginning.
If the window continues to close but then re-open slightly even after per-
forming the above procedure correctly, have the vehicle inspected by any

Driving

CAUTION
If you hear a squealing or scraping noise (brake pad wear indicators)
Have the brake pads checked and replaced by any authorized Lexus dealer
or repairer, or another duly qualified and equipped professional as soon as
possible.
Rotor damage may result if the pads are not replaced when needed.
Moderate levels of brake pad and disc wear allow enhanced front 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 the wear limits of the brake pads
and/or those of the brake discs are exceeded.
When the vehicle is stopped
Do not depress the accelerator pedal unnecessarily.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, causing an accident.
In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the “READY” indicator is on, and apply
the parking brake as necessary.
If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or backward, always depress the brake
pedal and securely apply the parking brake as needed.
Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

Driving
GS450h_300h_OM_OM30D53E_(EE)
When the steering lock cannot be released
Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning.
When “Check Entry & Start System” will be displayed on the multi-informa-
tion display
The system may be malfunctioning. Have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional immediately.
If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the power
switch with the shift lever in P and the brake pedal depressed, contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional immediately.
If the hybrid system is malfunctioning
P. 8 4 0
If the electronic key battery is depleted
P. 9 0 2
Operation of the power switch
When operating the power switch, one short, firm press is enough. If the
switch is pressed improperly, the hybrid system may not start or the power
switch mode may not change. It is not necessary to press and hold the
switch.
If attempting to restart the hybrid system immediately after turning the
power switch off, the hybrid system may not start in some cases. After turn-
ing the power switch off, please wait a few seconds before restarting the
hybrid system.
If the smart entry & start system has been deactivated in a customized setting “Steering Lock active” will be displayed
on the multi-information display.
Check that the shift lever is set in P. Press
the power switch while turning the steer-
ing wheel left and right.

2564-2. Driving procedures
GS450h_300h_OM_OM30D53E_(EE)
Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically in order to warm up. In this case, you will
become unable to switch to EV drive mode.
Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically
restart in the following situations. When EV drive mode is canceled, a buzzer
will sound and the EV drive mode indicator will flash and go off.
The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy monitor” display is
low.
(P. 131)
GS450h: Vehicle speed becomes more than about 40 km/h (25 mph).
GS300h: Vehicle speed becomes more than about 45 km/h (28 mph).
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance,
a prior notice screen will appear on the multi-information display.
Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 1 km (0.6 mile). Driving is possible at speeds of less than
approximately 40 km/h (25 mph) for GS450h or 45 km/h (28 mph) for
GS300h. However, depending on vehicle conditions, there are situations
when EV drive mode cannot be used.
(The distance that is possible depends on the hybrid battery [traction battery]
level and driving conditions.)
Fuel economy
Your Lexus is designed to achieve the best possible fuel economy during nor-
mal driving (using the gasoline engine and electric motor [traction motor]).
Driving in EV drive mode more than necessary may lower fuel economy. To prevent gasoline engine warm up in
order to reduce noises, start the hybrid
system without starting the gasoline
engine, pressing the power switch with
fully depressing the brake pedal and
pressing the EV drive mode switch.

Raindrop sensor (vehicles with rain-sensing windshield wipers)
If AUTO mode is selected while the power switch is in ON mode, the wip-
ers will operate once to show that AUTO mode is activated.
If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -
30°C (-22°F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than AUTO mode.
When the windshield wipers are in temporary operation
AUTO mode cannot be activated even if is pressed.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from
the rising or setting of the sun intermit-
tently strikes the windshield, or if bugs
etc. are present on the windshield.
CAUTION
Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched
or the windshield is subject to vibration in AUTO mode. Take care that
your fingers or anything else do not become caught in the windshield wip-
ers.
Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility.
This may lead to an accident, resulting in death or serious injury.
