The Pop Up Hood will operate when the vehicle detects an impact such as
the following:
The front bumper detects a frontal impact equivalent to or greater than
that of a pedestrian while the vehicle being driven within the opera-
tional speed range of approximately 25 to 55 km/h (16 to 34 mph).
(The system is operated by an impact of threshold level or greater, even
in the case of a minor collision that may not leave a trace on the front
bumper. Also, depending on the impact conditions or vehicle speed,
the system may be operated by a collision with a light or small object
or a small animal.)
In other situations the system may operate when an impact is applied to
the lower part of the vehicle or front bumper, such as the following:
• Colliding with a curb
• Falling into a deep hole
• Landing hard
• Hitting the slope of a parking lot, an undulating road, a protruding
object or falling object
Pop Up Hood operational conditions
CAUTION
When the Pop Up Hood is operated
Do not pull the hood lock release lever. Doing so after the Pop Up Hood has
operated will further raise the hood and may cause an injury.
Do not drive with the hood raised, as doing so may block the driver’s vision,
possibly causing an accident.
Do not forcibly push down the hood. As the popped up hood cannot be low-
ered by hand, doing so may deform the hood or cause an injury.
If the Pop Up Hood has operated, have the vehicle inspected by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped profes-
sional. If the Pop Up Hood has operated, stop the vehicle in a safe place and
contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
Do not touch the lifters immediately after the Pop Up Hood has operated, as
the lifters may be hot and burn you.

NOTICE
Pop Up Hood precautions
Make sure to close the hood before driving, as the system may not operate
properly if the hood is not fully closed.
Make sure that all 4 tires are of the specified size and inflated to the specified
tire pressure (P. 570). If tires of a different size are used, the system may
not operate properly.
If something has hit the area around the front bumper, the sensors may be
damaged even if the Pop Up Hood has not operated. Have the vehicle
inspected by any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional.
Do not remove or repair the parts or wiring of the Pop Up Hood, as doing so
may cause accidental operation or prevent the system from operating prop-
erly. If repair or replacement is necessary, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
Do not remove such components as the front bumper, hood or suspension, or
replace them with non-genuine parts, as doing so may prevent the system
from operating properly.
Do not install anything to the front bumper or hood, as doing so may prevent
the sensors from detecting an impact correctly and prevent the system from
operating properly.
Do not close the hood with force or apply load to the lifters, as doing so may
damage the lifters and prevent the system from operating properly.
Do not modify the suspension, as changes made to the vehicle height may
prevent the system from operating properly.

Studies have shown that installing a child restraint on a rear seat is much
safer than installing one on the front passenger seat.
Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (P. 7 0 )
If child restraint system regulations exist in the country where you
reside, please contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for the child restraint
system installation.
Lexus recommends that you use a child restraint system which con-
forms to the regulation ECE No.44.

When installing a child restraint system on the front passenger seat
Selecting an appropriate child restraint system
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
If the child is too large for a child restraint system, sit the child on a rear seat
and use the vehicle’s seat belt. (P. 38) When you have to use a child restraint sys-
tem on the front passenger seat, adjust the
following:
The seatback to the most upright position
The seat cushion to the highest position
The seat cushion to the fully rearward
position
CAUTION
Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly
secure the infant or child. It may result in death or serious injury (in the event
of sudden braking or an accident).

681-1. For safe use
IS300h_EE(OM53B95E)
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 depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute for a child restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle’s interior. This may
cause death or serious injury to the child in the event of a sudden stop, sudden
swerve or accident.
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 statis-
tics, the child is safer when properly restrained in the rear seat than in the
front seat.
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 5 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
A forward-facing child restraint system may be installed on the front passen-
ger seat only when it is unavoidable. A child restraint system that requires a
top tether strap should not be used in the front passenger seat since there is no
top tether strap anchor for the front passenger seat. Adjust the seatback as
upright as possible and always move the seat as far back as possible because
the front passenger airbag could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously injured.
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, center and rear pillars or roof side rails
from which the SRS side airbags or SRS curtain shield airbags deploy even if
the child is seated 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.
Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properly secured. If it is
not secured properly, it may cause death or serious injury to the child in the
event of a sudden stop, sudden swerve or accident.
