CAUTION
Hybrid battery (traction battery)
Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through any authorized Lexus dealer or repairer, or another duly qual-
ified and equipped professional. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
The hybrid battery may be illegally disposed of or dumped, and someone
may touch a high voltage part, resulting in an electric shock.
The hybrid battery is intended to be used exclusively with your hybrid
vehicle. If the hybrid battery is used outside of your vehicle or modified in
any way, accidents such as electric shock, heat generation, smoke genera-
tion, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an accident
is extremely high because the person receiving the vehicle may not be aware
of these dangers.

When stopped/during start off
The gasoline engine stops* when the vehicle is stopped.
During start off, the electric motor (traction motor) drives the
vehicle. At slow speeds or when traveling down a gentle
slope, the engine is stopped* and the electric motor (traction
motor) is used.
When shift position is in N, the hybrid battery (traction bat-
tery) will not be charged. Thus, shift to P when the vehicle is
stopped. In addition, when driving in heavy traffic, use D or
B.
*:However, when the hybrid battery (traction battery) need to
be charged or while the engine is being warmed up, the gas-
oline engine may not stop automatically.
During normal driving
The gasoline engine is predominantly used. The electric
motor (traction motor) charges the hybrid battery (traction
battery) as necessary.
When accelerating sharply
When the accelerator pedal is depressed heavily, the power of
the hybrid battery (traction battery) is added to that of the gas-
oline engine via the electric motor (traction motor).
When braking (regenerative braking)

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 B.
The brake pedal is depressed while driving with the shift position in D or
B.
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
The EV indicator comes on when driving
the vehicle using only the electric motor
(traction motor).

Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the
battery 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
discharge. 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 bat-
tery becomes fully discharged and you are unable to jump-start the vehi-
cle with the 12-volt battery, contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
If the shift position is in N, the hybrid battery (traction battery) will not
be charged. Always shift the shift position in P when the vehicle is
stopped. When driving in heavy traffic, operate the vehicle with the shift
position in D or B to avoid discharging the hybrid battery (traction bat-
tery).
Charging the 12-volt battery
P. 6 3 6
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
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

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 may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
Engine sounds may be heard when accelerating sharply.
Sounds may be heard due to regenerative braking when the brake pedal
is depressed and accelerator is loosened.
Other sounds, such as motors and mechanical noises, may be heard from
the brake system 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 vent on the side of
rear right 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. 667)

Hybrid warning message
A message is automatically displayed when a malfunction occurs
in the hybrid system or an improper operation is attempted.
If a warning message is shown
on the multi-information dis-
play, read the message and fol-
low the instructions.
(P. 578)
If a warning light comes on, a warning message is displayed, or the 12-volt
battery is disconnected
The hybrid system may not start. In that case, try to start the system again. If
the “READY” indicator does not come on, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Running out of fuel
When the vehicle has run out of fuel and the hybrid system cannot be
started, refuel the vehicle with at least enough gasoline to make the low fuel
level warning light (P. 575) go off. If there is only a small amount of fuel,
the hybrid system may not be able to start. (The minimum amount of fuel to
add to make the low fuel level warning light go out is about 11.8 L [3.1 gal.,
2.6 Imp.gal.], when the vehicle is on a level surface. This value may vary
when the vehicle is on a slope.)

CAUTION
Road accident cautions
If your vehicle is involved in an accident, observe the following precautions
to reduce the risk of death or serious injury:
Stop the vehicle in a safe place to prevent subsequent accidents.
While depressing the brake pedal, apply the parking brake and shift the
shift position to P to stop the hybrid system. Then, slowly release the
brake pedal.
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 front 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. 563)
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.
Hybrid battery (traction battery)
Your vehicle contains a sealed nickel-metal hydride battery. If disposed of
improperly, it is hazardous to the environment and there is a risk of severe
burns and electrical shock that may result in death or serious injury.
