lean forward too quickly. A slow, easy
motion will allow the belt to extend so that
you can move around fully.
■Automatic locking retractor (ALR)
When a passenger’s sh oulder belt is com-
pletely extended and then retracted even
slightly, the belt is locked in that position and
cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt
and then pull the belt out once more.

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.
●All of the doors will be unlocked.

●The brakes and stop lights will be con-
trolled automatically. ( P.297)
●The interior lights will turn on automati-
cally. ( P.337)
●The emergency flashers will be turned on
automatically. ( P.410)
●Fuel supply to the engine will be stopped.

●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.

• 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:
• 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

■PCS-linked Pop Up Hood operation
control
If the PCS (Pre-Collision System) deter-
mines that the possibility 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 le vel 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 lowe r 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 protruding 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
●A frontal impact applied to the front
bumper while driving at speeds outside
of the operational speed range
●A side impact or rear impact
●A vehicle rollover (In some accident situ-
ations, the Pop Up Hood may operate.)
WARNING
■When the Pop Up Hood is operated
●Do not pull the hood lock release lever.
Doing so after the Pop Up Hood has
operated will further raise the hood
and may cause an injury. Do not drive
with the hood raised, as doing so may
block the driver’s vision, possibly caus-
ing an accident.
●Do not forcibly push down the hood.
As the popped up hood cannot be
lowered by hand, doing so may deform
the hood or cause an injury.
●If the Pop Up Hood has operated, have
it replaced by your Lexus dealer. If the
Pop Up Hood has operated, stop the
vehicle in a safe place and contact
your Lexus dealer.
●Do not touch the lifters immediately
after the Pop Up Hood has operated,
as the lifters may be hot and burn you.
NOTICE
■Pop Up Hood precautions
●Make sure to close the hood before
driving, as the system may not operate
properly if the hood is not fully closed.
●Make sure that all 4 tires are of the
specified size and inflated to the speci-
fied tire pressure. If tires of a different
size are used, the system may not
operate properly.
●If something has hit the area around
the front bumper, the sensors may be
damaged even if the Pop Up Hood has
not operated. Have the vehicle
inspected by your Lexus dealer.

Riding with children
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child , until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch etc.
 Use the rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
( P.103, 145)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof or panoramic moon roof,
or other features of the vehicle. In addi-
tion, heat build-up or extremely cold
temperatures inside the vehicle can be
fatal to children.
Child restraint systems
Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.
Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child restraint
system to a rear seat. Be sure to fol-
low the installation method that is in
the operation manual enclosed with
the restraint system.

For safety and security
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt.
■Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
WARNING
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat.
●A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, adjust the seatback angle to the
most upright position, move the seat to
the rearmost position, and raise the
seat to the upper most position, even if
the “AIR BAG OFF” indicator light is
illuminated.
●Do not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front or rear pillars, or roof side rails
from which the SRS side airbags or
SRS curtain shield ai rbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Use child restraint system suitable to
the age and size of the child and install
it to the rear seat.
●If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.

■Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seat. (Buttons displaying
the location of the anchors are
attached to the seats.)
■When installing in the rear out-
board seats
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.
WARNING
●Do not allow children to play with the
seat belt. If the seat belt becomes
twisted around a child’s neck, it may
lead to choking or other serious inju-
ries that could result in death.
If this occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.
●Ensure that the belt and plate are
securely locked and the seat belt is not
twisted.
●Shake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.
●When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder.
●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
●When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
seat belts in positions next to the child
restraint without inte rfering with it or
affecting seat belt effectiveness. Be
sure your seat belt fits snugly across
your shoulder and low on your hips. If it
does not, or if it interferes with the
child restraint, move to a different posi-
tion. Failure to do so may result in
death or serious injury.
●When installing a child restraint system
in the rear center seat, adjust both seat
cushions to the same position and
align both seatbacks at the same
angle. Otherwise, the child restraint
system cannot be securely restrained
and this may cause death or serious
injuries in the event of sudden braking,
sudden swerving or an accident.
●If the seat is adjusted, reconfirm the
security of the child restraint system.
■When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. (
P.26)
■Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.
