This vehicle is equipped with an event
data recorder (EDR). The main pur-
Vehicle data recording
Event data recorder

pose of an EDR is to record, in certain
crash or near crash-like situations,
such as an air bag deployment or hit-
ting a road obstacle, data that will assist
in understanding how a vehicle’s sys-
tems performed. The EDR is designed
to record data related to vehicle
dynamics and safety systems for a
short period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is designed to
record such data as:
 How various systems in your vehicle
were operating;
 Whether or not the driver and pas-
senger safety belts were buck-
led/fastened;
 How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
 How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by
your vehicle only if a non-trivial crash
situation occurs; no data are recorded
by the EDR under normal driving con-
ditions and no personal data (e.g.,
name, gender, age, and crash location)
are recorded. However, other parties,
such as law enforcement, could com-
bine the EDR data with the type of per-
sonally identifying data routinely
acquired during a crash investigation.
To read data recorded by an EDR,
special equipment is required, and
access to the vehicle or the EDR is needed. In addition to the vehicle man-
ufacturer, other parties, such as law
enforcement, that have the special
equipment, can read the information if
they have access to the vehicle or the
EDR.

Disclosure of the EDR data
Lexus will not disclose the data recorded in
an EDR to a third party except when:
• An agreement from the vehicle’s owner (or the lessee for a leased vehicle) is
obtained
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for research purposes without disclosing
information about the specific vehicle or
vehicle owner
The SRS airbag and seat belt preten-
sioner devices in your Lexus contain
explosive chemicals. If the vehicle is
scrapped with the airbags and seat belt
pretensioners not deployed, this may
cause an accident such as fire. Be sure
to have the systems of the SRS airbag
and seat belt pretensioner removed
and disposed of by a qualified service
shop or by your Lexus dealer before
you scrap your vehicle.

Your vehicle is equipped with ADVA NCED 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 compon ents diagram above. This information
includes crash severity and occupant info rmation. 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.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
●A loud noise and white powder will be
emitted.
●Parts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seat s, parts of the front
and rear pillars, and r oof side rails may be
hot for several minutes. The airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.67)
●All of the doors will be unlocked.
( P.102)
●The brakes and stop lights will be con-
trolled automatically. ( P.248)
●The interior lights will turn on automati-
cally. ( P.278)
●The emergency flashers will turn on auto-
matically. ( P.358)
●For 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.
■SRS airbag deployment conditions (SRS
front airbags)
●The 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
●Depending on the type of collision, it is

621-4. Hybrid system
■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 obta ined 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 th e 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 (1 6 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.393
■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 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

631-4. Hybrid system

For safety and security
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 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
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 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.420)
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

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 dr iving style and driving
conditions.
■Starting the hybrid system in an
extremely cold environment (for vehi-
cles sold in except Canada)
When the hybrid battery (traction battery)
is extremely cold (below approximately -
22°F [-30°C]) 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.
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 (right side). 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 de ath 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 sh ift the shift lever
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 ar e exposed inside or
outside your vehicle, an electric shock
may occur. Neve r touch exposed
electric wires.
●For vehicles sold in Canada: If a fluid
leak occurs, do not touch the fluid as it
may be strong alkaline electrolyte
from the hybrid battery (traction bat-
tery). If it comes into contact with your
skin or eyes, wash it off immediately
with a large amount of water or, if pos-
sible, boric acid solution. Seek imme-
diate medical attention.
