1-2. Child safety

When securing some types of child
restraint systems in rear seat, it may not
be possible to properly use the seat
belts in positions next to the child
restraint without interfering with it or
affecting seat belt effectiveness. Be
sure your seat belt fits snugly across
your shoulder and low on your hips. If it
does not, or if it interferes with the child
restraint, move to a different position.
Failure to do so may result in death or
serious injury.



When installing a child restraint in
the rear seats, adjust the front seat
so that it does not interfere with the
child or child restraint system.



When installing a child seat with
support base, if the child seat inter-
feres with the seatback when latch-
ing it into the support base, adjust
the seatback rearward until there is

no interference.



If the seat belt shoulder anchor is
ahead of the child seat belt guide,
move the seat cushion forward.



When installing a junior seat, if the
child in your child restraint system is
in a very upright position, adjust the
seatback angle to the most comfort-
able position. And if the seat belt
shoulder anchor is ahead of the
child seat belt guide, move the seat
cushion forward.

Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.

(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 gasoline engine via
the electric motor (traction motor).

■

When braking (regenerative brak-
ing)

The wheels operate the electric motor
(traction motor) as a power generator,
and the hybrid battery (traction bat-
tery) is charged.

■

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 M.

• The brake pedal is depressed while driv-

ing with the shift position in D or M.

●

Vehicles with GPF system: While the

GPF system (

The EV indicator comes on when the vehi-

cle is driven using only the electric motor

(traction motor) or the gasoline engine is

stopped.

■

Conditions in which the gasoline engine

may not stop

The gasoline engine starts and stops auto-

matically. However, it may not stop auto-

matically in the following conditions:

●

During gasoline engine warm-up

●

During hybrid battery (traction battery)

charging

●

When the temperature of the hybrid bat-

tery (traction battery) is high or low

Depending on the circumstances, the gaso-

line engine may also not stop automatically

in other situations.

■

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 (traction

battery) will slowly discharge. For this rea-

son, be sure to drive the vehicle at least

once every few months for at least 30 min-

utes or 16 km (10 miles). If the hybrid bat-

tery (traction battery) becomes fully

discharged and you are unable to start the

hybrid system, contact any authorized

Sounds and vibrations specific to a

hybrid electric vehicle

Because there is no engine sound or vibra-

tion, it is easy to mistake the hybrid electric

vehicle for being off when it is actually still

running, as indicated by the “READY” indi-

cator being illuminated. For safety, make

sure to always shift the shift position to P

and apply the parking brake 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.

●

Relay operating sounds such as a snap or

soft clank will be emitted from the hybrid

battery (traction battery), behind the rear

seats, when the hybrid system is started

or stopped.

●

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 transmis-

sion when the gasoline engine starts or

stops, when driving at low speeds, or dur-

ing idling.

●

Engine sounds may be heard when

accelerating sharply.

●

Sounds may be heard due to regenera-

tive braking when the brake pedal is

depressed or as the accelerator pedal is

released.

●

Vibration may be felt or sounds may be

heard 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.

■

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.499) go off. If there is only a small

amount of fuel, the hybrid system may not

be able to start. (The standard amount of

fuel is about 13 L [3.4 gal., 2.8 Imp. gal.],

when the vehicle is on a level surface. This

value may vary when the vehicle is on a

slope. Add extra fuel when the vehicle is

inclined.)

Hybrid system precautions

Take care when handling the hybrid system, as it is a high voltage system (about
650 V at maximum) as well as contains parts that become extremely hot when
the hybrid system is operating. Obey the warning labels attached to the vehi-
cle.

Electromagnetic waves

●

High voltage parts and cables on hybrid

electric vehicles incorporate electro-

magnetic shielding, and therefore emit

approximately the same amount of elec-

tromagnetic waves as conventional gaso-

line powered vehicles or home electronic

appliances.

●

Your vehicle may cause sound interfer-

ence in some third party-produced radio

parts.

■

Hybrid battery (traction battery)

The hybrid battery (traction battery) has a

limited service life. The lifespan of the

hybrid battery (traction battery) can

change in accordance with driving style and

driving conditions.

■

Starting the hybrid system in an

extremely cold environment

When the hybrid battery (traction battery)

is extremely cold (below approximately

-30°C [-22°F]) under the influence of the

outside temperature, it may not be possible

to start the hybrid system. In this case, try to

start the hybrid system again after the tem-

perature of the hybrid battery increases due

to the outside temperature increase etc.

■

Declaration of conformity

This model conforms to hydrogen emis-

sions according to regulation ECE100

(Battery electric vehicle safety).

WARNING

■

High voltage precautions

This vehicle has high voltage DC and AC

systems as well as a 12-volt system. DC

and AC high voltage is very dangerous

and can cause severe burns and electric

shock that may result in death or serious

injury.

●

Never touch, disassemble, remove or

replace the high voltage parts, cables

or their connectors.

●

The hybrid system will become hot

after starting as the system uses high

voltage. Be careful of both the high

voltage and the high temperature, and

always obey the warning labels

attached to the vehicle.

●

Never try to open the service plug

access hole located behind the rear

seat. The service plug is used only

when the vehicle is serviced and is

subject to high voltage.

■

Road accident cautions

Observe the following precautions to

reduce the risk of death or serious injury:

●

Stop the vehicle in a safe place to pre-

vent subsequent accidents. While

depressing the brake pedal, apply the

parking brake and shift the shift posi-

tion 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 elec-

tric wires.

1-4. Hybrid system

For safety and security

WARNING

●

Do not touch the battery if liquid is

leaking from or adhering to it.

If electrolyte (carbonate ester-based

organic electrolyte) from the hybrid

battery (traction battery) comes into

contact with the eyes or skin, it could

cause blindness or skin wounds. In the

unlikely event that it comes into con-

tact with the eyes or skin, wash it off

immediately with a large amount of

water, and seek immediate medical

attention.

●

If electrolyte is leaking from the hybrid

battery (traction battery), do not

approach the vehicle.

Even in the unlikely event that the

hybrid battery (traction battery) is

damaged, the internal construction of

the battery will prevent a large amount

of electrolyte from leaking out. How-

ever, any electrolyte that does leak out

will give off a vapor. This vapor is an

irritant to skin and eyes and could

cause acute poisoning if inhaled.

●

Do not bring burning or high-temper-

ature items close to the electrolyte.

The electrolyte may ignite and cause a

fire.

●

If a fire occurs in the hybrid electric

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 four 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 a fire. (



P.489)

●

Carefully inspect the ground under the

vehicle. If you find that liquid has

leaked onto the ground, the fuel sys-

tem may have been damaged. Leave

the vehicle as soon as possible.

■

Hybrid battery (traction battery)

●

Your vehicle contains a sealed lith-

ium-ion battery.

●

Never resell, hand over or modify the

hybrid battery. To prevent accidents,

hybrid batteries that have been

removed from a disposed vehicle are

collected through any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. 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 dis-

posed of or dumped, and it is hazard-

ous to the environment or someone

may touch a high voltage part, result-

ing in an electric shock.

• The hybrid battery is intended to be

used exclusively with your hybrid elec-

tric vehicle. If the hybrid battery is used

outside of your vehicle or modified in

any way, accidents such as electric

shock, heat generation, smoke gener-

ation, 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.

●

If your vehicle is disposed of without

the hybrid battery having been

removed, there is a danger of serious

electric shock if high voltage parts,

cables and their connectors are

touched. In the event that your vehicle

must be disposed of, the hybrid battery

must be disposed of by any authorized

Lexus retailer or Lexus authorized

repairer, or any reliable repairer. If the

hybrid battery is not disposed of prop-

erly, it may cause electric shock that

can result in death or serious injury.

1-4. Hybrid system

There are air intake vents on each side
of the rear seatback with the purpose
of cooling the hybrid battery (traction
battery).
If the vents are blocked, it may interfere
with the cooling of the hybrid battery
(traction battery).

If input/output of the hybrid battery (trac-
tion battery) becomes limited and the dis-
tance that the vehicle can be driven using
the electric motor (traction motor) is
reduced, the fuel economy may be
reduced.

When a certain level of impact is
detected by the impact sensor, the
emergency shut off system blocks the
high voltage current and stops the fuel
pump to minimize the risk of electrocu-
tion and fuel leakage. If the emergency
shut off system activates, your vehicle
will not restart. To restart the hybrid
system, contact any authorized Lexus
retailer or Lexus authorized repairer,
or any reliable repairer.

A message is automatically displayed
when a malfunction occurs in the
hybrid system or an improper opera-
tion is attempted.
If a warning message is shown on the
multi-information display, read the
