Be sure to check with your Lexus
dealer for precautionary measures or
special instructions regarding installa-
tion of a mobile two-way radio system.
High voltage parts and cables on the
hybrid vehicles emit approximately the
same amount of electromagnetic
waves as the conventional gasoline
powered vehicles or home electronic
appliances despite of their electro-
magnetic shielding.
Unwanted noise may occur in the
reception of the mobile two-way radio.
The vehicle is equipped with sophisti-
cated computers that will record cer-
tain data, such as:
• Engine speed/Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cam-
eras. Contact your Lexus dealer for
the location of recording cameras
The recorded data varies according to
the vehicle grade level and options with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.

Data Transmission
Your vehicle may transmit the data
recorded in these computers to Lexus
without notification to you.
Data usage
Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.
Lexus will not disclose the recorded data
to a third party except:
• With the consent of the vehicle owner or
with the consent of the lessee if the vehi-
cle is leased
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
 Recorded image information can be
erased by your Lexus dealer.
The image recording function can be dis-
abled. However, if the function is disabled,

Driver’s seat belt buckle switch
Airbag sensor assembly
“PASSENGER AIR BAG” indicator lights
Front passenger’s seat belt buckle switch
Front impact sensors
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system components diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.
QIf the SRS airbags deploy (inflate)
OSlight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
OA loud noise and white powder will be
emitted.
OParts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front
and rear pillars, and roof side rails, may
be hot for several minutes. The airbag
itself may also be hot.
OThe windshield may crack.
OThe hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.65)
OAll of the doors will be unlocked.

OThe brakes and stop lights will be con-
trolled automatically. ( P.253)
OThe interior lights will turn on automati-
cally. ( P.283)
OThe emergency flashers will turn on auto-
matically. ( P.358)
OFor Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, the system is designed to send an
emergency call to the response center,
notifying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assistance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.
(
 P.55)
•An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
QSRS airbag deployment conditions (SRS
front airbags)
OThe SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12 - 18
mph [20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will be
considerably higher in the following situ-
ations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes
under, the bed of a truck

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 illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
QWhen 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.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine is
warming up, etc., the gasoline engine will
not automatically stop.
QDuring normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
(traction battery) as necessary.
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.

601-4. Hybrid system
QWhen 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).
QWhen 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.
QRegenerative 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).
OThe accelerator pedal is released while
driving with the shift lever in D or S.
OThe brake pedal is depressed while driv-
ing with the shift lever in D or S.
QEV indicator
The EV indicator comes on when the vehi-
cle is driven using on ly the electric motor
(traction motor) or the gasoline engine is
stopped.
QConditions 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
*:
ODuring gasoline engine warm-up
ODuring hybrid battery (traction battery) charging
OWhen the temperature of the hybrid bat-
tery (traction battery) is high or low
OWhen the heater is switched on
*: Depending on the circumstances, the
gasoline engine may also not stop auto-
matically in other situations.
QCharging 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.
QCharging the 12-volt battery
 P.393
QAfter 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.
QSounds and vibratio ns 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:
OMotor sounds may be heard from the
engine compartment.
OSounds may be heard from the hybrid
battery (traction battery) under the rear
seats when the hybrid system starts or
stops.
ORelay operating sounds such as a snap or

For safety and security
soft clank will be emitted from the hybrid
battery (traction battery), under the rear
seats, when the hybrid system is started
or stopped.
OSounds from the hybrid system may be
heard when the trunk lid is open.
OSounds may be heard from the transmis-
sion when the gasoline engine starts or
stops, when driving at low speeds, or
during idling.
OEngine sounds may be heard when
accelerating sharply.
OSounds may be heard due to regenera-
tive braking when the brake pedal is
depressed or as the accelerator pedal is
released.
OVibration may be felt when the gasoline
engine starts or stops.
OCooling fan sounds may be heard from
the air intake vent under the rear seat.
QMaintenance, repair, recycling, and dis-
posal
Contact your Lexus dealer regarding main-
tenance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
QCustomization
Settings (e.g. on/off operation of the EV
indicator) can be changed.
(Customizable features: P.421)
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).
QAcoustic Vehicle Alerting System
In the following cases, the Acoustic Vehicle
Alerting System may be difficult for sur-
rounding people to hear.
OIn very noisy areas
OIn the wind or the rain
QIf “Acoustic Vehicle Alerting System
