When installing in the rear center
seat

There are no LATCH anchors behind
the rear center seat. However, the
inboard LATCH anchors of the out-
board seats, which are 18.1 in. (460
mm) apart, can be used if the child
restraint system manufacturer’s
instructions permit use of those

anchors with the anchor spacing
stated.
Child restraint systems with rigid lower
attachments cannot be installed in the
center seat. This type of child restraint
system can only be installed in the out-
board seat.

■

Laws and regulations pertaining to

anchors

The LATCH system conforms to

FMVSS225 or CMVSS210.2.

Child restraint systems conforming to

FMVSS213 or CMVSS213 specifications

can be used.

This vehicle is designed to conform to SAE

J1819.

WARNING

■

When installing a child restraint sys-

tem

Observe the following precautions.

Failure to do so may result in death or

serious injury.

●

When using the LATCH anchors, be

sure that there are no foreign objects

around the anchors and that the seat

belt is not caught behind the child

restraint system.

●

Follow all installation instructions pro-

vided by the child restraint system

manufacturer.

●

Never attach two child restraint system

attachments to the same anchor. In a

collision, one anchor may not be

Important! Read this information about
exposure to radio frequency signals
before using Safety Connect;
The Safety Connect system installed in
your vehicle is a low-power radio trans-
mitter and receiver. It receives and also
sends out radio frequency (RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.



ANSI (American National Stan-
dards Institute) C95.1 [1992]



NCRP (National Council on Radia-
tion Protection and Measurement)
Report 86 [1986]



ICNIRP (International Commission
on Non-Ionizing Radiation Protec-
tion) [1996]

Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over

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 the shift lever is in N, the hybrid
battery (traction battery) is not being
charged.

Hybrid system features

Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.

The hybrid system combines the use of a gasoline engine and an electric motor
(traction motor) according to driving conditions, improving fuel efficiency and
reducing exhaust emissions.

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 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 decelera-

tion 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 lever in D or S.

●

The brake pedal is depressed while driv-

ing with the shift lever in D or S.

■

EV indicator

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

●

When the heater is switched on

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

tery (traction battery) becomes fully

discharged and you are unable to start the

hybrid system, contact your Lexus dealer.

■

Charging the 12-volt battery



P.441

■

After the 12-volt battery has discharged

or when the terminal has been removed

and installed during exchange, etc.

The gasoline engine may not stop even if

the vehicle is being driven by the hybrid bat-

tery (traction battery). If this continues for a

few days, contact your Lexus dealer.

■

Sounds and vibrations specific to a

hybrid vehicle

There may be no engine sound or vibration

even though the vehicle is able to move with

the “READY” indicator is illuminated. For

safety, apply the parking brake and make

sure to shift the shift lever 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.

●

soft clank will be emitted from the hybrid

battery (traction battery), behind the rear

seats, when the hybrid system is started

or stopped.

●

Sounds from the hybrid system may be

heard when the back door is open.

●

Sounds may be heard from the transmis-

sion 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 regenera-

tive braking when the brake pedal is

depressed or as the accelerator pedal is

released.

●

Vibration may be felt when the gasoline

engine starts or stops.

●

Cooling fan sounds may be heard from

the air intake vents under the rear seats.

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.413) 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 2.9 gal. [11.0 L, 2.4 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

vehicles incorporate electromagnetic

shielding, and therefore emit approxi-

mately the same amount of electromag-

netic waves as conventional gasoline

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.

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 under 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:

●

Pull your vehicle off the road, shift the

shift lever to P, apply the parking brake,

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 elec-

tric wires.

●

If a fluid leak occurs, do not touch the

fluid as it may be strong alkaline elec-

trolyte from the hybrid battery (trac-

tion battery). If it comes into contact

with your skin or eyes, wash it off

immediately with a large amount of

water or, if possible, boric acid solu-

tion. 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 danger-

ous.

1-4. Hybrid system

For safety and security

The air intake/discharge vents for the
hybrid battery (traction battery) are
located under the rear seats and in lug-
gage compartment respectively. If the
air intake vents are blocked, it could
lead to a reduction in hybrid battery
(traction battery) output.

WARNING

●

If your vehicle needs to be towed, do

so with all 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.405)

●

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)

●

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 your Lexus dealer.

Do not dispose of the battery yourself.

Unless the battery is properly col-

lected, the following may occur, result-

ing 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 vehi-

cle. If the hybrid battery is used outside

of your vehicle or modified in any way,

accidents such as electric shock, heat

generation, smoke generation, 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 your Lexus

dealer or a qualified service shop. If

the hybrid battery is not disposed of

properly, it may cause electric shock

that can result in death or serious

injury.
