2022 LEXUS ES300h warning

341-1. For safe use
WARNING
OIf the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS front airbags
for the driver will judge that the driver
is wearing the seat belt even though
the seat belt has not been connected.
In this case, the SRS front airbags for
the driver 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.
OThe SRS front passenger airbag also
deploys with considerable 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 air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright.
OImproperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying air-
bag. 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.43)
ODo not sit on the edge of the seat or
lean against the dashboard.
ODo not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
ODo not allow the front seat occupants
to hold items on their knees.
ODo not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
ODo not allow anyone to kneel on the
passenger seats toward the door or
put their head or hands outside the
vehicle.

For safety and security
WARNING
ODo not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.
ODo not attach anything to areas such
as a door, windshield, side window,
front or rear pillar, roof side rail and
assist grip.
ODo not hang coat hangers or other
hard objects on the coat hooks. All of
these items could become projectiles
and may cause death or serious injury,
should the SRS curtain shield airbags
deploy.
OIf a vinyl cover is put on the area where
the SRS knee airbag will deploy, be
sure to remove it.
ODo not use seat accessories which
cover the parts where the SRS side air-
bags inflate as they may interfere with
inflation of the SRS airbags. Such
accessories may prevent the side air-
bags from activating correctly, disable
the system or cause the side airbags to
inflate accidentally, resulting in death
or serious injury.
ODo not strike or apply significant levels
of force to the area of the SRS airbag
components or the front doors.
Doing so can cause the SRS airbags to
malfunction.
ODo not touch any of the component
parts immediately after the SRS air-
bags have deployed (inflated) as they
may be hot.
OIf 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.
OIf 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.
ODo 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 air-
bags for the front passenger may not
deploy in the event of a collision.
QModification and disposal of SRS air-
bag 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.
OInstallation, removal, disassembly and
repair of the SRS airbags
ORepairs, modifications, removal or
replacement of the steering wheel,
instrument panel, dashboard, seats or
seat upholstery, front, side and rear pil-
lars, roof side rails, front door panels,
front door trims or front door speakers
OModifications to the front door panel
(such as making a hole in it)

WARNING
QFront passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system.

ous injury.
OWear the seat belt properly.
OMake sure the front passenger’s seat
belt plate has not been left inserted
into the buckle befo re someone sits in
the front passenger seat.

381-1. For safe use
WARNING
OMake sure the “PASSENGER AIR
BAG OFF” indicator light is not illumi-
nated when using the seat belt
extender for the front passenger seat.
If the “PASSENGER AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the
seat belt buckle, and reconnect the
seat belt. Reconnect the seat belt
extender after making sure the “PAS-
SENGER AIR BAG ON” indicator
light is illuminated. If you use the seat
belt extender while the “PASSENGER
AIR BAG OFF” indicator light is illu-
minated, the SRS airbags for the front
passenger will not activate, which
could cause death or serious injury in
the event of a collision.
ODo not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
ODo 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.
ODo not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
ODo not put objects under the front pas-
senger seat.
ODo not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “PASSEN-
GER 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 severe
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.
OIf an adult sits in the front passenger
seat, the “PASSENGER AIR BAG
ON” indicator light is illuminated. If the
“PASSENGER AIR BAG OFF” indi-
cator is illuminated, ask the passenger
to sit up straight, well back in the seat,
feet on the floor, and with the seat belt
worn correctly. If the “PASSENGER
AIR BAG OFF” indicator still remains
illuminated, either ask the passenger
to move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
OWhen it is unavoidable to install a for-
ward-facing child restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(  P.45)
ODo not modify or remove the front
seats.
ODo 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 classification system.
In this case, contact your Lexus dealer
immediately.
OChild restraint systems installed on the
rear seat should not contact the front
seatbacks.
ODo not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
ODo not modify or replace the uphol-
stery of the front seat.
ODo 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.

Exhaust gas precautions
Harmful substance to the human
body is included in exhaust gases if
inhaled.
WARNING
Exhaust gases include harmful carbon
monoxide (CO), which is colorless and
odorless. Observe the following precau-
tions.
Failure to do so may cause exhaust gases
enter the vehicle and may lead to an
accident caused by light-headedness, or
may lead to death or a serious health
hazard.
QImportant points while driving
OKeep the trunk lid closed.
OIf you smell exhaust gases in the vehi-
cle even when the trunk lid is closed,
open the windows and have the vehi-
cle inspected at your Lexus dealer as
soon as possible.
QWhen parking
OIf the vehicle is in a poorly ventilated
area or a closed area, such as a
garage, stop the hybrid system.
ODo not leave the vehicle with the
hybrid system operating for a long
time.
If such a situation cannot be avoided,
park the vehicle in an open space and
ensure that exhaust fumes do not enter
the vehicle interior.
ODo not leave the hybrid system oper-
ating in an area with snow build-up, or
where it is snowing. If snowbanks build
up around the vehicle while the hybrid
system is operating, exhaust gases
may collect and enter the vehicle.
QExhaust pipe
The exhaust system needs to be checked
periodically. If there is a hole or crack
caused by corrosion, damage to a joint
or abnormal exhaust noise, be sure to
have the vehicle inspected and repaired
by your Lexus dealer.
