system into the rear seat, allow the
shoulder belt to retract until the
child restraint system is securely in
place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.

1-8. Safety information
CAUTION
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discom-
fort to the child. (P. 7 5 )
■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 or other passen-
gers may be seriously injured or even killed in the event of sudden braking, sudden
swerving 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.
●Adjust the front passen ger seat so that it
does not interfere with the child restraint
system.
●Only put a forward-facing child restraint
system on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is
illuminated. Failure to do so may result in
death or serious injury if the airbags deploy
(inflate).

Before driving
CAUTION
●When a booster seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from
the child’s neck, but not so that it could fall off the child’s shoulder. Failing to do so
may result in death or serious injury in the event of sudden braking, sudden
swerving or an accident.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Push and pull the child restraint system from side to side and forward to be sure it
is secure.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provid ed by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when inst alling a child restraint system, 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 sudden braking, sudden
swerving or an accident.
■To correctly attach a child restraint system to the anchors
When using the LATCH anchors, be sure that there are no foreign objects around
the anchors and that the seat belt is not cau ght behind the child restraint. Make sure
the child restraint system is securely at tached, or it may cause death or serious
injury to the child or other passengers in the event of a sudden stop, sudden swerve
or accident.

CAUTION
• 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.
●Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a place such
as the glove box or on the floor, it may be lit accidentally when luggage is loaded
or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the wind shield or windows. Do not place contain-
ers such as air fresheners on the instru ment panel or dashboard. Adhesive discs
or containers may act as lenses, causing a fire in the vehicle.
●Do not leave a door or window open if the curved glass is coated with a metal-
lized film such as a silver-colored one. Reflected sunlight may cause the glass to
act as a lens, causing a fire.
●Always apply the parking brake, select shift position P, stop the hybrid system,
and lock the vehicle. 
Do not leave the vehicle unattended while the hybrid system is operating.
●Do not touch the exhaust pipe while the hybrid system is operating or immedi-
ately after turning the hybrid system off. 
Doing so may cause burns.
●Do not leave the hybrid system operating in an area with snow build-up, or where
it is snowing. If snowbanks build up arou nd the vehicle while the hybrid system is
operating, exhaust gases may collect and enter the vehicle. This may lead to
death or a serious health hazard.
■Exhaust gases
Exhaust gases include harm ful carbon monoxide (CO), which is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health hazard.
●If the vehicle is in a poorly ventilated area, stop the hybrid system. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle. This may
lead to death or a serious health hazard.
●The exhaust system should be checked occasionally. 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. Failure to do so
may allow exhaust gases to enter the vehicle, resulting in death or a serious health
hazard.
