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
transmitter 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-

Safety information for Safety
Connect

tion) [1996]

Those standards were based on com-
prehensive and periodic evaluations of
the relevant scientific literature. Over
120 scientists, engineers, and physi-
cians from universities, and govern-
ment health agencies and industries
reviewed the available body of
research to develop the ANSI Stan-
dard (C95.1).
The design of Safety Connect com-
plies with the FCC guidelines in addi-
tion to those standards.

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

Hybrid system features

Your vehicle is a Hybrid Electric Vehicle. It has characteristics different from
conventional 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 effi-
ciency and reducing exhaust emissions.

charged.

: When the hybrid battery (traction bat-

tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop. (



P.61)

■

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 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

gasoline engine may also not stop auto-
matically 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 reason, be sure to drive the vehicle at

least once every few months for at least 30

minutes or 10 miles (16 km). If the hybrid

battery (traction battery) becomes fully dis-

charged and you are unable to start the

hybrid system, contact your Lexus dealer.

■

Charging the 12-volt battery



P.400

■

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

battery (traction battery). If this continues

for a few days, contact your Lexus dealer.

Sounds and vibrations specific to a

Hybrid Electric 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.

●

Sounds may be heard from the hybrid

battery (traction battery) behind the rear

seats when the hybrid system starts or

stops.

●

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 from the hybrid system may be

heard when the back door is open.

●

Sounds may be heard from the hybrid

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 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 vent under the right side of

the rear seat.

■

Maintenance, repair, recycling, and dis-

posal

Contact your Lexus dealer regarding main-

tenance, repair, recycling and disposal. Do

not dispose of the vehicle yourself.

■

Customization

Settings (e.g. on/off operation of the EV

indicator) can be changed.

(Customizable features:



P.427)

When driving with the gasoline engine
stopped, a sound, which changes in
accordance with the driving speed, will
be played in order to warn people
nearby of the vehicle’s approach. This
sound may be heard inside the vehicle.
The sound will stop when the vehicle
speed exceeds approximately 22 mph
(35 km/h).

■

Acoustic Vehicle Alerting System

In the following cases, the Acoustic Vehicle

Alerting System may be difficult for sur-

rounding people to hear.

●

In very noisy areas

●

In the wind or the rain

Also, as the Acoustic Vehicle Alerting Sys-

tem is installed on the front of the vehicle, it

may be more difficult to hear from the rear

of the vehicle compared to the front.

: This function can only be used in the

mainland U.S.A. It cannot be used in
other states and territories, including
Alaska and Hawaii.

This system operates based on the
driving situation and traffic information
to enhance fuel economy.

Predictive SOC

control

The following types of control are per-
formed based on data such as road
and traffic information during route
guidance by the navigation system to
help ensure that the vehicle efficiently
uses electricity.



When there is a long downhill slope
along the route, the system reduces
the hybrid battery (traction battery)
level before reaching the slope to
help ensure charging capacity for
regenerative braking while traveling
downhill.



When traffic congestion is pre-
dicted along the route, the system
helps ensure a certain battery level
before reaching congested roads to
reduce the frequency of starting the
engine to charge the hybrid battery
(traction battery) due to low battery
levels.

: SOC means state of charge

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.382) 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 1.8 gal. [7.0 L, 1.5 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.)

■

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.

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 underneath the

rear seats. 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

electric 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.

1-4. Hybrid system

There is an air intake vent under the
right side of the rear seat with the pur-
pose of cooling the hybrid battery
(traction battery).
If the vent is 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.

WARNING

●

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 front wheels (2WD models) or

four wheels (AWD models) 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.373)

●

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 Lexus dealers. 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

Electric Vehicle. If the hybrid battery is

used outside of your vehicle or modi-

fied in any way, accidents such as elec-

tric shock, heat generation, smoke

generation, an explosion and electro-

lyte 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 prop-

erly, it may cause electric shock that

can result in death or serious injury.

NOTICE

■

Hybrid battery (traction battery)

Do not carry large amounts of water

such as water cooler bottles in the vehi-

cle. If water spills onto the hybrid battery

(traction battery), the battery may be

damaged. Have the vehicle inspected by

your Lexus dealer.
