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 cannot be extended.
While pushing the child
restraint 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.
If the child restraint has a top tether strap, the top tether strap should
be latched onto the top tether strap anchor. (

CAUTION
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to tighten only. This could cause injury or dis-
comfort to the child. (→P. 3 4 )
■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 correctly fixed in place, the child or other passen-
gers may be seriously injured or even killed in the event of a 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.
●Adjust the front passenger 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).

CAUTION
■When installing a child restraint system
●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 an accident or a sudden brak-
ing.
●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.
●After securing a child restraint system, never adjust the seat.
●Follow all installation instructions provided by the child restraint system manufac-
turer.
■Do not use a seat belt extender
If a seat belt extender is used when installing 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 a 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 a sudden braking or
an accident.

Exhaust gas precautions
Harmful substance to the human body is included in exhaust gases if
inhale.
CAUTION
Exhaust gases include harmful carbon monoxide (CO), which is colorless and odor-
less. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an acci-
dent caused by light-headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the trunk lid closed.
●If you smell exhaust gases in the vehicle even when the trunk lid is closed, open
the windows and have the vehicle inspected at your Lexus dealer as soon as pos-
sible.
■When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a garage, stop
the hybrid system.
●Do not leave the vehicle with the hybrid system on 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 hybrid system operating in an area with snow build-up, or where
it is snowing. If snowbanks build up around the vehicle while the hybrid system is
operating, 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.

◆When stopped/during start off
The gasoline engine stops when the vehicle is stopped. During start off,
the electric motor (traction motor) drives the vehicle. At slow speeds or
when traveling down a gentle slope, the engine is stopped and the elec-
tric motor (traction motor) is used.
◆During normal driving
The gasoline engine is predominantly used. The electric motor (traction
motor) charges the hybrid battery (traction battery) as necessary.
◆When accelerating sharply
When the accelerator pedal is depressed heavily, the power of the
hybrid battery (traction battery) is added to that of the gasoline engine
via the electric motor (traction motor).
◆When braking (regenerative braking)
The electric motor (traction motor) charges the hybrid battery (traction
battery).
When driving with the gasoline engine stopped, a sound, which changes
in accordance with the driving speed, will be played in order to warn peo-
ple nearby of the vehicle’s approach. The sound will stop when the vehicle
speed exceeds approximately 15 mph (25 km/h).
