■Rear-facing Infant seat/convertible seat
Place the child restraint system
on the rear seat facing the rear of
the vehicle.
Run the seat belt through the
child restraint system and insert
the plate into the buckle. Make
sure that the belt is not twisted.
Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt can-
not be extended.
While pushing the child restraint
system down 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.

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

to the manufacturer’s instructions
and insert the plate into the
buckle. Make sure that the belt is
not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child’s
shoulder and that the lap belt is as
low as possible. ( →P. 3 2 )

Child restraint systems conforming to FMVSS213 or CMVSS213 specifications can be
used.
This vehicle is designed to conform to the SAE J1819.

■When installing a booster seat
To prevent the belt from going into ALR lo ck mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only . This could cause injury or discomfort to
the child. ( →P. 3 3 )
■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 passengers
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 passenge r seat so that it does
not interfere with the child restraint system.
●Only put a forward-facing child restraint sys-
tem 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 illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).

■When installing a child restraint system
●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 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 acci-
dent.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left and right, and forward and backward to ensure
that it has been securely installed.
●If the seat is adjusted, reconfirm the security of the child restraint system.
●Follow all installation instructions provided by the child restraint system manufacturer.
●When securing some types of child restraint systems in rear seat, it may not be possi-
ble to properly use the seat belts in positions next to the child restraint without inter-
fering with it or affecting seat belt effectiveness. Be sure your seat belt fits snugly
across your shoulder and low on your hips. If it does not, or if it interferes with the child
restraint, move to a different position. Failure to do so may result in death or serious
injury.
■Do not use a seat belt extender
If a seat belt extender is used when installi ng 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 caught behind the child restraint system. Make sure
the child restraint system is securely attached , or it may cause death or serious injury to
the child or other passengers in the event of sudden braking, sudden swerving or an
accident.

Hybrid system features
The illustration is an example for explanat ion and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
Your vehicle is a hybrid vehicle. It has characteristics different from conven-
tional vehicles. Be sure you are closely familiar with the characteristics of your
vehicle, and operate it with care.
The hybrid system combines the use of a gasoline engine and an electric
motor (traction motor) according to driving conditions, improving fuel effi-
ciency and reducing exhaust emissions.

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery).
●The accelerator pedal is released while driving with the shift lever in D or S.
●The brake pedal is depressed while driv ing with the shift lever in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automati-
cally in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
■Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery does not
need to be charged from an outside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction battery) will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 10
miles (16 km). If the hybrid battery (traction battery) becomes fully discharged and you
are unable to start the hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
→P. 5 3 1
■After the 12-volt battery has discharged or when the terminal has been removed and
installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer. The EV indicator comes on when the vehicle is
driven using only the electric motor (traction
motor) or the gasoline engine is stopped.
