* 3
: In the event the front passenger does not wear a seat belt.
* 4

system may not recognize him/her as a child. Factors which may affect this can be the
physique or posture.

RX350/RX350L_U WARNING ■
Front passenger occupant classification system precautions
Observe the following precau tions regarding the front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious injury. ●
Wear the seat belt properly. ●
Make sure the front passenger’s seat belt plate has not been left inserted into the
buckle before someone sits in the front passenger seat.●
Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON”
indicator light is illuminated. If you use the seat belt extender while the “AIR BAG
OFF” indicator light is illuminated, the SRS airbags for the front passenger will not
activate, which could cause death or seri ous injury in the event of a collision.●
Do not apply a heavy load to the front pa ssenger seat or equipment (e.g. seatback
pocket). ●
Do not put weight on the front passenger 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 passenger seat.

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.

RX350/RX350L_UExhaust gas precautions Harmful substance to the human body is contained in exhaust gases if inhaled.WARNING
Exhaust gases contain harmful carbon monoxi de (CO), which is colorless and odorless.
Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident
caused by light-deadness, or may lead to death or a serious health hazard.■
Important points while driving ●
Keep the back door closed. ●
If you smell exhaust gases in the vehicle even when the back door is closed, open the
windows and have the vehicle inspected at your Lexus dealer as soon as possible.■
When parking ●
If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop the
engine. ●
Do not leave the vehicle with the engine running 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. ●
Do not leave the engine running in an area with snow build-up, or where it is snowing.
If snowbanks build up around the vehicle while the engine is running, exhaust gases
may collect and enter the vehicle. ■
Exhaust 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.

60 1-2. Child safety
RX350/RX350L_U WARNING ■
When using a child restraint system
If the head restraint interferes with the inst allation of the child restraint system, and the
head restraint can be removed, remove the head restraint.
If the head restraint cannot be remove d, raise it to the uppermost position.
●
When a booster seat is installed, always en sure that the 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 coul d 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. ●
A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restrain t system on the front
passenger seat, raise the seatback as much as
possible, move the seat to the rearmost posi-
tion, and raise the seat to the highest 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 air-
bags or SRS curtain shield airbags deploy
even if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.
●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat. ●
Adjust the front passenger seat so that it does
not interfere with the child restraint system.
