For safety and security
Driver’s seat position sensor
Driver’s seat belt buckle switch
Airbag sensor assembly
Front impact sensors
Pop Up Hood computer assembly
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 sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with no n-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 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.
●The windshield may crack.
●The hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.69)
●All of the doors will be unlocked.
( P.113)
●The brakes and stop lights will be con-
trolled automatically. ( P.302)
●The interior lights will turn on automati-
cally. ( P.343)
●The emergency flashers will be turned on
automatically. ( P.416)
●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.58)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■PCS-linked SRS airbag deployment
control (vehicles with Lexus Safety Sys-
tem + A)
If the PCS (Pre-Collision System) deter-
mines that the possibility of a side collision is
high, the SRS side and curtain shield air-
bags will be prepared to operate.
■SRS airbag deployment conditions (SRS
front airbags/SRS seat cushion airbags)
●The SRS front airbags and SRS seat cush-
ion airbags will deploy in the event of an
impact that exceed s the set threshold
level (the level of fo rce corresponding to
an approximately 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wall
that does not move or deform).
However, this threshol d velocity will be
considerably higher in the following situa-
tions:

■Pop Up Hood precautions
●Before scrapping your vehicle, make sure
to contact your Lexus dealer.
●The Pop Up Hood system cannot be
reused once it has operated. Have it
replaced by your Lexus dealer.
■PCS-linked Pop Up Hood operation
control
If the PCS (Pre-Collision System) deter-
mines that the possibilit y of a collision with a
pedestrian or bicyclist is high, the Pop Up
Hood will be prepared to operate.
■Pop Up Hood operational conditions
The Pop Up Hood will operate when the
vehicle detects an impact such as the fol-
lowing:
●The front bumper detects a frontal impact
equivalent to or grea ter than that of a
pedestrian while the vehicle being driven
within the operational speed range of
approximately 16 to 34 mph (25 to 55
km/h). (The system is operated by an
impact of threshold level or greater, even
in the case of a minor collision that may
not leave a trace on the front bumper.
Also, depending on the impact condi-
tions or vehicle speed, the system may
operate by a collision with a light or small
object or a small animal.)
●In other situations, such as the following
the system may operate when an impact
is applied to the lower part of the vehicle
or front bumper:
• Colliding with a curb
• Falling into a deep hole
•Landing hard
• Hitting the slope of a parking lot, an undulating road, a pr otruding object or
falling object
■Conditions under which the Pop Up
Hood may not operate properly
●If a pedestrian collides with the right or
left corner of the front bumper or the side
of the vehicle. As such impacts may be
difficult to detect, the system may not
operate.
●If the vehicle speed is not detected cor-
rectly, such as if the vehicle is sliding side-
ways, the system may not operate
properly.
■Conditions under which the Pop Up
Hood will not operate
The Pop Up Hood will not operate in the
following situations:
●Colliding with a lying person
Pop Up Hood
In the event of a frontal collision
with a body, such as a pedestrian,
the Pop Up Hood system raises the
hood to reduce the possibility of a
serious impact to the pedestrian’s
head area by adding clearance to
the engine compartment.
When the sensors located at the
back of the front bumper detect a
frontal impact with a body, such as a
pedestrian, which meets or
exceeds the threshold level while
the vehicle is being driven within
the operational speed range, the
system operates.

1-4.Hybrid system
■System components
The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
■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 position 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.
■During normal driving
The gasoline engine is predominantly
used. The electric motor (traction
motor) charges the hybrid battery
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.

(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 obta ined 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.
■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
●When the shift position is in M
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.445
■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 position 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.
●Relay operating sounds such as a snap or
soft clank will be em itted 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
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 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.
■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
Some functions can be customized.
(  P.479)
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. The
sound will stop when the vehicle speed
exceeds approximately 15 mph (25
km/h).
■Vehicle proximity notification system
In the following cases, the vehicle proximity
notification system may be difficult for sur-
rounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification
system 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.
