her as a child depending on his/her physique and posture.
*
2: In the event the front passenger does not wear a seat belt.
*3: When a large child who has outgrown a child restraint system sits in the front passenger seat, the sy stem may recognize him/her as an
adult depending on his/her physique and posture.
*
4: Never install a rear-facing child restraint system on the front passen- ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable.

■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classifi-
cation system.
●Wear the seat belt properly.
●Make sure the front passenger’s seat belt tab has not been left inserted into the
buckle before someone sits in the front passenger seat.
●Make sure the “AIRBAG OFF” indicator li ght is not illuminated when using the
seat belt extender for th e front passenger seat. If the “AIRBAG OFF” indicator
light is illuminated, disconnect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect the seat belt extender after making sure
the “AIRBAG ON” indicator light is illumina ted. If you use the seat belt extender
while the “AIRBAG OFF” indicator light is illuminated, the front passenger airbag
and side airbag on the front passenger side may not activate correctly, 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. arm-
rest).
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seat back from the second seat.
●Do not let a second seat 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.
●Do not recline the front passenger seatback so far that it touches a rear seat. This
may cause the “AIRBAG OFF” indicator light to be illuminated, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear se at, return the seatback to a position where it does
not touch the rear seat. Keep the front pa ssenger seatback as upright as possible
when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.

CAUTION
■Front passenger occupant classification system precautions
●If an adult sits in the front passenger se at, the “AIRBAG ON” indicator light is illu-
iminated. If the “AIRBAG OFF” indicator is illuminated, ask th e passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIRBAG OFF” indicator still remain illuminated, either ask the pas-
senger to move to the rear seat, or if th at is not possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a forw ard-facing child restraint system on the
front passenger seat, install the child rest raint system on the front passenger seat
in the proper order. ( P. 77)
●Do not remove the front seat.
●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 in the detection sys-
tem. In this case, contact your Lexus dealer immediately.
●Do not use a seat accessory, such as a cushion or seat cover, that covers the seat
cushion surface.
●Child restraint systems installed on the second seat should not contact the front
seatbacks.

1-7. Safety information
CAUTION
■Child restraint precautions
●For effective protection in automobile accidents and sudden stops, a child must
be properly restrained, using a seat belt or child restraint system depending on
the age and size of the child. Holding a child in your arms is not a substitute for a
child restraint system. In an accident, th e child can be crushed against the wind-
shield, or between you and the vehicle's interior.
●Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed on the rear seat. According to accident statistics, the
child is safer when properly restrained in the rear seat than in the front seat.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIRBAG OFF” indicator light is illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
●A forward-facing child restraint system shou ld allowed to be installed on the front
passenger seat only when it is unavoidable. Always move the seat as far back as
possible even if the “AIR BAG OFF” indicator light is illuminated, because the
front passenger airbag could inflate with considerable speed and force. Other-
wise, the child may be killed or seriously injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, 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 collision.
●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 pillar or roof side rail from which the side air-
bags or curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all inst allation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or seri ous injury to the child in the event of a
sudden stop or accident.

■When installing a booster seat
Do not fully extend the shoulder belt to prevent the belt from going to ALR lock
mode: ( P. 31)
●ALR mode causes the belt to tighten only which could cause injury or discomfort
to the child.
●Do not allow the child to play with the seat belt or the child could be killed or seri-
ous injured.
■When installing a child restraint system
Follow the directions given in the child restraint system installation manual and fix
the child restraint system securely in place.
If the child restraint system is not correctl y fixed in place, the child may be injured or
even killed in the event of sudden braking or an accident.
●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.
●Only put a forward facing or booster child
seat on the front seat when unavoidable.
When installing a forward facing or
booster child restraint on the front passen-
ger seat, move the seat as far back as possi-
ble even if the “AIRBAG OFF” indicator
light is illuminated. Failing to do so may
result in death or serious injury if the air-
bags deploy (inflate).

2-1. Driving procedures
CAUTION
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident and result in death or serious injury.
■When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than “P” or “N” the vehicle may accelerate sud-
denly and unexpectedly, and may cause an accident.
●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
check that exhaust fumes do not enter the vehicle interior.
●Always keep a foot on the brake pedal while the engine is running to prevent an
accident caused by the vehicle moving.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in the vehi-
cle when it is in the sun.
Failure to do so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic
material of eye glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of
the vehicle, and may also cause a short circuit in the vehicle's electrical com-
ponents.
●Always apply the parking brake, shift the shift lever to “P”, stop the engine and
lock the vehicle.
Do not leave the vehicle unattend ed while the engine is running.
●Do not touch the exhaust pipe while the engine is running or immediately after
turning the engine off.
Doing so may cause burns.
●Do not leave the engine running in an area with snow build up, or where snow is
expected to fall.
Exhaust gases may enter the vehicle and cause gas poisoning.
