821-2. Hybrid system
GS450h_300h_OM_OM30D53E_(EE)
Regenerative braking
In the following situations, kinetic energy is converted to electric energy and
deceleration force can be obtained in conjunction with the recharging of the
hybrid battery (traction battery).
The accelerator pedal is released while driving with the shift position in D
or S.
The brake pedal is depressed while driving with the shift position in D or S.
EV indicator
Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop
automatically in the following conditions:
During gasoline engine warm-up
During hybrid battery (traction battery) charging
When the temperature of the hybrid battery (traction battery) is high or low
When the heater is switched on
Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the bat-
tery does not need to be charged from an outside source. However, if the
vehicle is left parked for a long time the hybrid battery will slowly dis-
charge. For this reason, be sure to drive the vehicle at least once every few
months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
becomes fully discharged and you are unable to jump-start the vehicle with
the 12-volt battery, contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged. Always put the shift lever in P when the vehicle is stopped. When
driving in heavy traffic, operate the vehicle with the shift lever in D or S to
avoid discharging the battery.
Charging the 12-volt battery
P. 9 1 2 The EV indicator comes on when the
vehicle is driven using only the electric
motor (traction motor) or the gasoline
engine is stopped.

For safety and security
After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid
battery (traction battery). If this continues for a few days, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional.
Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
Motor sounds may be heard from the engine compartment.
Sounds may be heard from the hybrid battery (traction battery) behind the
rear seats when the hybrid system starts or stops.
Sounds from the hybrid system may be heard when the trunk lid is open.
Sounds may be heard from the hybrid transmission when the hybrid system
starts or stops.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal is
depressed.
Vibration may be felt when the gasoline engine starts or stops.
Cooling fan sounds may be heard from the air intake vents on the both sides
of the rear seatback.
Maintenance, repair, recycling, and disposal
Contact any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional regarding maintenance, repair, recycling and dis-
posal. Do not dispose of the vehicle yourself.
Customization
Settings (e.g. on/off operation of the EV indicator) can be changed.
(Customizable features: P. 942)

CAUTION
Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
Pull your vehicle off the road, apply the parking brake, shift the shift lever
to P, and turn the hybrid system off.
Do not touch the high voltage parts, cables and connectors.
If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
If a fluid leak occurs, do not touch the fluid as it may be strong alkaline
electrolyte from the hybrid battery (traction battery). If it comes into con-
tact with your skin or eyes, wash it off immediately with a large amount of
water or, if possible, boric acid solution. Seek immediate medical atten-
tion.
If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using
even a small amount of water may be dangerous.
If your vehicle needs to be towed, do so with rear wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause an electricity leakage leading to a fire. (P. 822)
Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

GS450h_300h_OM_OM30D53E_(EE)
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
To extend the life of the vehicle, observing the following precautions is rec-
ommended:
For the first 300 km (186 miles):
Avoid sudden stops.
For the first 800 km (500 miles):
Do not tow a trailer.
For the first 1000 km (621 miles):
• Do not drive at extremely high speeds.
• Avoid sudden acceleration.
• Do not drive continuously in low gears.
• Do not drive at a constant speed for extended periods.
