WARNING
■General precautions while driving
Driving under the infl uence: Never drive
your vehicle when under the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment an d reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mi stakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
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 (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

For safety and security
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
■Replacing the belt after the
pretensioner has been activated
If the vehicle is involv ed in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
■PCS-linked seat belt pretensioner con-
trol
If the PCS (Pre-Collision System) deter-
mines that the possibility of a collision with a
vehicle is high, the seat belt pretensioners
will be prepared to operate.
Seat belt pretensioners (front
seats and outboard rear seats)WARNING
■Seat belt pretensioners
●Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the seat belt
pretensioner for the front passenger’s
seat may not activate in the event of a
collision.
●If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

301-1. For safe use
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US
motor vehicle safety standards (FMVSS20 8). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtain ed from the sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As th e 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, an d 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. ( P.91)
●The brakes and stop lights will be con-
trolled automatically. (P.230)
●The interior lights will turn on automati-
cally. (P.254)
●The emergency flashers will turn on auto-
matically. ( P.320)
●Fuel supply to the engine will be stopped.
(P.328)
●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 assi stance 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.54)
• 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 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
front of the vehicle “u nderrides”, or goes
under, the bed of a truck
●Depending on the type of collision, it is
possible that only the seat belt
pretensioners will activate.
●The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
■SRS airbag deployment conditions (SRS
side and curtain shield airbags)
●The SRS side and curtain shield airbags
will deploy in the event of an impact that
exceeds the set threshold level (the level
of force corresponding to the impact
force produced by an approximately
3300 lb. [1500 kg] vehicle colliding with
the vehicle cabin from a direction per-

WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death or seri-
ous injury.
●The driver and all passengers in the
vehicle must wear their seat belts
properly.
The SRS airbags are supplemental
devices to be used with the seat belts.
●The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if the
driver is very close to the airbag.
The National Highway Traffic Safety
Administration (NHT SA) advises: Since
the risk zone for the dr iver’s airbag is the
first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from
your driver airbag provides you with a
clear margin of safety. This distance is
measured from the center of the steering
wheel to your breastbone. If you sit less
than 10 in. (250 mm) away now, you can
change your driving position in several
ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many
drivers can achieve the 10 in. (250
mm) distance, even with the driver seat
all the way forward, simply by reclining
the back of the seat somewhat. If
reclining the back of your seat makes it
hard to see the road, raise yourself by
using a firm, non-slip pery cushion, or
raise the seat if your vehicle has that
feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your head
and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls.
●If the seat belt extender has been con-
nected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front
airbags may not activate correctly in a
collision, resulting in death or serious
injury in the event of a collision. Be
sure to wear the seat belt with the seat
belt extender.
●The SRS front passenger airbag also
deploys with consid erable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the
airbag as possible with the seatback
adjusted, so the front passenger sits
upright.
●Improperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying airbag.
An infant or child who is too small to
use a seat belt should be properly
secured using a child restraint system.
Lexus strongly recommends that all
infants and children be placed in the
rear seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. (
P.41)

For safety and security
WARNING
●If a vinyl cover is put on the area where
the SRS knee airbag will deploy, be
sure to remove it.
●Do not use seat accessories which
cover the parts where the SRS side
airbags inflate as they may interfere
with inflation of the SRS airbags. Such
accessories may prevent the side
airbags from activating correctly, dis-
able the system or cause the side
airbags to inflate accidentally, resulting
in death or serious injury.
●Do not strike or apply significant levels
of force to the area of the SRS airbag
components. Doing so can cause the
SRS airbags to malfunction.
●Do not touch any of the component
parts immediately after the SRS
airbags have deployed (inflated) as
they may be hot.
●If breathing becomes difficult after the
SRS airbags have deployed, open a
door or window to allow fresh air in, or
leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi-
ble to prevent skin irritation.
●If the areas where the SRS airbags are
stored, such as the steering wheel pad
and front and rear pillar garnishes are
damaged or cracked, have them
replaced by your Lexus dealer.
●Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the SRS front
airbags for the front passenger may
not deploy in the event of a collision.
■Modification and disposal of SRS
airbag system components
Do not dispose of your vehicle or per-
form any of the following modifications
without consulting your Lexus dealer.
The SRS airbags may malfunction or
deploy (inflate) accidentally, causing
death or serious injury.
●Installation, remova l, disassembly and
repair of the SRS airbags
●Repairs, modifications, removal or
replacement of the steering wheel,
instrument panel, dashboard, seats or
seat upholstery, front, side and rear pil-
lars or roof side rails
●Repairs or modifications of the front
fender, front bumper, or side of the
occupant compartment
●Installation of a grille guard (bull bars,
kangaroo bar, etc. ), snow plows,
winches or roof luggage carrier
●Modifications to the vehicle’s suspen-
sion system
●Installation of elec tronic devices such
as mobile two-way radios and CD
players
●Modifications to your vehicle for a per-
son with a physical disability

WARNING
●Make sure the “AIR BAG OFF” indica-
tor light is not illuminated when using
the seat belt extender for the front pas-
senger seat. If the “AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the seat
belt buckle, and reconnect the seat
belt. Reconnect the se at belt extender
after making sure the “AIR BAG ON”
indicator light is illu minated. If you use
the seat belt extender while the “AIR
BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front
passenger will not activate, which
could cause death or serious injury in
the event of a collision.
●Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
●Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
●Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator light to be illuminated,
which indicates that the SRS airbags
for the front passenger will not activate
in the event of a seve re accident. If the
seatback touches the rear seat, return
the seatback to a position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible when the vehicle is moving.
Reclining the seatback excessively
may lessen the effectiveness of the
seat belt system.
●If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator light
is illuminated. If the “AIR BAG OFF”
indicator is illuminated, ask the passen-
ger to sit up straig ht, well back in the
seat, feet on the floor, and with the seat
belt worn correctly. If the “AIR BAG
OFF” indicator still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a for-
ward-facing child re straint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(
P.42)
●Do not modify or remove the front
seats.
●Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant cla ssification system.
In this case, contact your Lexus dealer
immediately.
●Child restraint system s installed on the
rear seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the uphol-
stery of the front seat.
●Do not place anything between the
console box and front passenger seat.
Otherwise, the system may not detect
the front passenger properly, leading
to improper operation of the airbags.
●Adjust the front passe nger seat so that
the head restraint does not touch the
ceiling. If the head re straint is left in
contact with the ceiling, the system
may not detect the front passenger
properly, leading to improper opera-
tion of the airbags.

943-2. Opening, closing and locking the doors and trunk
Trunk
The trunk can be opened using the
trunk opener, entry function or
wireless remote control.
WARNING
Observe the following precautions.
Failure to do so may result in death or
serious injury.
■Before driving
●Make sure that the trunk lid is fully
closed. If the trunk lid is not fully
closed, it may open unexpectedly
while driving and hit near-by objects or
luggage in the trun k may be thrown
out, causing an accident.
●Do not allow children to play in the
trunk.
If a child is accidentally locked in the
trunk, they could suffer from heat
exhaustion, suffocation or other inju-
ries.
●Do not allow a child to open or close
the trunk lid.
Doing so may cause the trunk lid to
open unexpectedly, or cause the
child’s hands, head , or neck to be
caught by the closing trunk lid.
■Important points while driving
Never let anyone sit in the trunk. In the
event of sudden braking or a collision,
they are susceptible to death or serious
injury.
■Using the trunk
Observe the following precautions.
Failure to do so may cause parts of the
body to be caught, resulting in serious
injury.
●Remove any heavy loads, such as snow
and ice, from the trunk lid before
opening it. Failure to do so may cause
the trunk lid to suddenly shut again
after it is opened.
●When opening or closing the trunk lid,
thoroughly check to make sure the
surrounding area is safe.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●Use caution when opening or closing
the trunk lid in wind y weather as it may
move abruptly in strong wind.
●The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an
incline than on a level surface, so
beware of the trunk lid unexpectedly
opening or closing by itself. Make sure
that the trunk lid is fully open and
secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure
to press it lightly on its outer surface. If
the trunk handle is used to fully close
the trunk lid, it may result in hands or
arms being caught.
●Do not attach any accessories other
than genuine Lexus parts to the trunk
lid. Such additional weight on the trunk
lid may cause the lid to suddenly shut
again after it is opened.
