SRS airbag precautions ●
Improperly seated and/or restrained infant s 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 chil d restraint system. Lexus strongly recom-
mends that all infants and children be placed in the rear seats of the vehicle and prop-
erly restrained. The rear se ats are safer for infants an d children than the front
passenger seat. (  P. 55)●
Do not sit on the edge of the seat or lean
against the dashboard. ●
Do not allow a child to stand in front of the
SRS front passenger airbag unit or sit on the
knees of a front passenger. ●
Do not allow the front seat occupants to hold
items on their knees. ●
Do not lean against the door, the roof side rail
or the front, side and rear pillars.
●
Do not allow anyone to kneel on the passen-
ger seats toward the door or put their head or
hands outside the vehicle.

If the SRS airbags deploy (inflate) ●
Slight abrasions, burns, brui sing etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) 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 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. ●
For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
the system is designed to send an emerge ncy call to the response center, notifying
them of the vehicle’s location (without needing to push the “SOS” button) and an agent
will attempt to speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency ser-
vices. (  P. 568)

RX350/RX350L_U WARNING ■
Front passenger occupant classification system precautions ●
Do not recline the front passeng er seatback so far that it touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to be illuminated, whic h indicates that the
SRS airbags for th e front passenger will no t activate in the even t 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 effec-
tiveness of the seat belt system. ●
If an adult sits in the fron t passenger seat , the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator 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 “AIR BAG OFF” indicator still remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the fron t passenger seat fully
rearward. ●
When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. (  P. 57)●
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 indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.●
Child restraint systems insta lled on the rear se at should not contact the front seat-
backs. ●
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 upholstery of the front seat. ●
Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.

●
It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch, etc. ●

children opening the door while driving or operating the power window acci-
dentally. ●
Do not let small children operate equipment which may catch or pinch body
parts, such as the power wind ow, hood, back door, seats etc.
Riding with children Observe the following precautions wh en children are in the vehicle.

the key.
Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a

When installing child restraint system to a front passenger seat is unavoidable,
adjust the seat as follows and install the child restraint system. ●
Raise the seatback as much as
possible ●
Move the seat to the rearmost
position ●
Raise the seat to the highest posi-
tion ●
If the head restraint interferes
with the installation of the child
restraint system, and the head
restraint can be removed, remove
the head restraint If the head restraint cannot be removed, raise it to the uppermost position.When using a child restraint system
WARNING ■
When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Never install a rear-facing ch ild restraint system on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the even t of an accident, the force
of the rapid inflation of the front passenger airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is inst alled on the front passenger
seat. ●
A forward-facing child restraint system ma y be installed on the front passenger 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.
