Electronic key battery depletion
The standard battery life is 1 to 2 years. (The card key battery life is about a
year and a half.)
If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 867)
As the electronic key always receives radio waves, the battery will become
depleted even if the electronic key is not used. The following symptoms
indicate that the electronic key battery may be depleted. Replace the battery
when necessary. (P. 777)
• The smart entry & start system or the wireless remote control does not
operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
To avoid serious deterioration, do not leave the electronic key within 1 m (3
ft.) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
•Table lamps
• Induction cookers

CAUTION
Trunk easy closer (vehicles with power trunk lid)
Power trunk lid (if equipped)
Observe the following precautions when operating the power trunk lid.
Failure to do so may cause serious injury.
Check the safety of the surrounding area to make sure there are no obsta-
cles 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 suddenly shut 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 lid 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 shut, 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 lid may not operate, causing itself to malfunction, or
the trunk lid may suddenly shut 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 fingers or any-
thing else in the trunk lid, as this may
cause bone fractures or other serious

2163-5. Opening, closing the windows and moon roof
GS450h_300h_OM_OM30D53E_(EE)
The power windows can be operated when
The power switch is in ON mode.
Operating the power windows after turning the hybrid system off
The power windows can be operated for approximately 45 seconds even after
the power switch is turned to ACCESSORY mode or turned off. They can-
not, however, be operated once either front door is opened.
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
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

Make sure that the parking brake is set and shift the shift lever to
D.
Gently depress the accelerator pedal.
Release the parking brake.
When starting off on a uphill
The brake hold is available. (P. 269)
Driving in the rain
Drive carefully when it is raining, 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 espe-
cially slippery.
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 sur-
face, preventing the steering and brakes from operating properly.
Breaking in your new Lexus

GS450h_300h_OM_OM30D53E_(EE)
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid
system operating. This prevents the vehicle from creeping.
When driving the vehicle
Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake pedal
will result in sudden acceleration that may lead to an accident.
• When backing up, you may twist your body around, leading to a diffi-
culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the
vehicle only slightly. This allows you to depress the brake and acceler-
ator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake
pedal using your left foot may delay response in an emergency, result-
ing in an accident.
The driver should pay extra attention to pedestrians when the vehicle is
powered only by the electric motor (traction motor). Because there is no
engine noise, the pedestrians may misjudge the vehicle’s movement.
Do not drive the vehicle over or stop the vehicle near flammable materi-
als.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.

2444-1. Before driving
GS450h_300h_OM_OM30D53E_(EE)
Your vehicle will handle differently when towing a trailer. In order
to avoid accident, death or serious injury, keep the following in
mind when towing:
Checking connections between trailer and lights
Stop the vehicle and check the operation of the connection
between the trailer and lights after driving for a brief period as
well as before starting off.
Practicing driving with a coupled trailer
Get the feel for turning, stopping and reversing with the trailer
coupled by practicing in an area with no or light traffic.
When reversing with a coupled trailer, hold the section of the
steering wheel nearest to you and rotate clockwise to turn the
trailer left or counterclockwise to turn it right. Always rotate a
little at a time to prevent steering error. Have someone guide
you when reversing to lessen the risk of an accident.
NOTICE
When the rear bumper strengthening material is aluminum
Ensure the steel bracket part does not come directly in contact with that
area.
When steel and aluminum come into contact, there is a reaction similar to
corrosion, which will weaken the section concerned and may result in dam-
age. Apply a rust inhibitor to parts that will come in contact when attaching
a steel bracket.
