Preparations for safe driving with children in the vehicle

Riding with children

If a child which is not large enough to correctly wear a seat belt intended for adults
is to ride in the vehicle, use a child restraint system. Child restraint systems are
designed to keep children safe.
To ensure safety, observe the following when children are in the vehicle.

●

Make sure that children always wear a seat belt.
If a child is not wearing a seat belt, in a collision, they may collide with a window,
other passenger, or the interior of the vehicle. Also, if a child is riding on the
lap of another passenger, in a collision, they may collide with a window, other
passenger, or the interior of the vehicle.

●

Seat children in the rear seats.
It is recommended that children sit in the rear seats to avoid accidental contact
with the driver's controls.

●

Do not allow children to operate equipment such as the doors, windows, etc.
Do not let children operate equipment such as the doors, power windows, seats,
etc. as a part of their body may become pinched.
To prevent children from opening and closing the doors and power windows, use
the child-protector locks and window lock switch.

WARNING

●

Never leave children unattended in the vehicle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.

●

Do not leave children unattended in the vehicle.
Children may accidentally cause the vehicle to move, leading to an accident, or start a
fire.

●

Do not leave people or animals in the vehicle.
The temperature inside the vehicle can become extremely high during the daytime,
possibly leading to heat stroke or death.

●

Do not allow children to ride on the lap of a passenger.
If a child is riding on the lap of another passenger, in a collision, they may collide with a
window, another passenger, or the interior of the vehicle. Make sure that children wear
a seat belt or use a child restraint system.

●

Use a child restraint system for small children.

WARNING

If a child which is not large enough to correctly wear a seat belt is to ride in the vehicle,
use a child restraint system.

●

Use child restraint systems correctly.
Child restraint systems are designed to protect children in a collision or sudden stop.
Make sure to securely install child restraint systems and use them correctly.

●

Replace child restraint systems which have been involved in a collision.
If the vehicle has been involved in a collision, it is possible that an installed child
restraint system has been damaged and will not be able to deliver the same level of
impact absorption performance, even if the outside of it looks normal.

●

When a child restraint system is not in use, secure it so that it does not interfere with
driving.
When removing a child restraint system, store it outside of the vehicle or securely in
the luggage compartment.

Seating positions for children

It is recommended that children sit in the rear seats to avoid accidental contact
with the driver’s controls. In the event of an accident, the force of deployment of the
SRS front passenger airbag can cause death or serious injury to a child seated on
the front passenger’s seat. Do not allow a child to ride on the front passenger’s seat
unless it is unavoidable.

WARNING

●

When installing a child restraint system to the front passenger’s seat is unavoidable,
move the seat as far back as possible, and install the child restraint system so that it
faces forward. If the child restraint system is not installed correctly, in the event of an
accident, the force of deployment of the SRS front passenger airbag can cause death
or serious injury.

●

Never install a rear-facing child restraint system on the front passenger seat even if the
"AIR BAG 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 serious injury to
the child if the rear-facing child restraint system is installed on the front passenger seat.

●

A forward-facing child restraint system may be installed on the front passenger 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.

●

A forward-facing child restraint system may be installed on the front passenger seat
only when it is unavoidable. When installing a forward-facing child restraint system on

WARNING

the front passenger seat, move the seat as far back as possible, and raise the seat to
the upper most position, even if the "AIR BAG OFF" indicator light is illuminated. If
the head restraint interferes with the child restraint system installation and the head
restraint can be removed, remove the head restraint.

●

Do not allow children to lean against the doors, roof side rails, or pillars. In the event
of an accident, the force of deployment of an SRS airbag can cause death or serious
injury to a child.

●

When adjusting the driver’s seat, if it contacts a child or child restraint system, install
the child restraint system to the rear seat behind the front passenger’s seat.

●

Adjust the front passenger seat so that it does not interfere with the child or child
restraint system.

●

If a child which is over 100 cm tall is to ride in the vehicle, use a booster seat. When
using a booster seat, make sure that the seat belt is worn correctly.

Child restraint system

Points to remember

The laws of all 50 states of the U.S.A. as well as Canada now require the use of
child restraint systems.

●

Prioritize and observe the warnings, as well as the laws and regulations for child
restraint systems.

●

Use a child restraint system until the child becomes large enough to properly
wear the vehicle’s seat belt.

●

Choose a child restraint system that suits your vehicle and is appropriate to the
age and size of the child.

WARNING

■

When a child is riding

Observe the following precautions. Failure to do so may result in death or serious injury.

●

For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system which is correctly
installed. For installation details, refer to the operation manual enclosed with the child
restraint system. General installation instruction is provided in this manual.

●

Lexus strongly urges the use of a proper child restraint system that conforms to the
weight and 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.

●

Holding a child in your or someone else’s arms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between the
holder and the interior of the vehicle.

■

Handling the child restraint system

If the child restraint system is not properly 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 vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has damage that is not readily visible. In such cases, do not
reuse the restraint system.

●

For Puerto Rico: Depending on the child restraint system, installation may be difficult
or impossible. In those cases, check whether the child restraint system is suitable for
installment in the vehicle. Be sure to install and observe the usage rules after carefully
reading the child restraint system fixing method in this manual, as well as the operation
manual enclosed with the child restraint system.

1-5. Preparations for safe driving with children in the vehicle

WARNING

●

Except for Puerto Rico: Make sure you have complied with all installation instructions
provided with the child restraint system manufacturer and that the system is properly
secured.

●

Keep the child restraint system properly secured on the seat even if it is not in use. Do
not store the child restraint system unsecured in the passenger compartment.

●

If it is necessary to detach the child restraint system, remove it from the vehicle.

Child restraint system installation method

Child restraint system fixed with a child restraint LATCH anchor

WARNING

■

When installing a child restraint system

Observe the following precautions. Failure to do so may result in death or serious injury.

●

When using LATCH anchors, make sure that the area around the anchors is free of
objects and that the seat belt will not be caught behind the child restraint system.

●

Follow all installation instructions provided by the child restraint system manufacturer.

●

Never attach two child restraint system attachments to the same anchor. In a collision,
one anchor may not be strong enough to hold two child restraint system attachments
and may break. If the LATCH anchors are already in use, use the seat belt to install a
child restraint system in the center seat.

●

When securing some types of child restraint systems in rear seats, it may not be
possible to properly use the seat belts in positions next to the child restraint without
interfering 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.

●

If the seat is adjusted, reconfirm the security of the child restraint system.

Laws and regulations pertaining to anchors

The LATCH system conforms to FMVSS225 or CMVSS210.2.
