●It is recommended that children sit in the rear seats to avoid accidental con-
tact with the shift lever, wiper switch etc.
●Use the rear door child-protector lock or the window lock switch to avoid
children opening the door while driving or operating the power window acci-
dentally.
●Do not let small children operate equipment which may catch or pinch body
parts, such as the power window, hood, trunk, seats etc.
Safety information for children
Observe the following precautions when children are in the vehicle.
Use a child restraint system appropriate for the child, until the child becomes
large enough to properly wear the vehicle’s seat belt.
CAUTION
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. There is also a
danger that children may injure themselves by playing with the windows, the moon roof
or other features of the vehicle. In addition, heat build-up or extremely cold tempera-
tures inside the vehicle can be fatal to children.

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 appropriate 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. 6 7 )
●If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly quali-
fied and equipped professional for the child restraint system installation.

If there is gap between the child seat and the seatback, tilt the seatback rearward
until good contact is achieved.
If the seatbelt shoulder anchor is ahead of the child seat belt guide, move the seat
cushion forward.
• For installing a junior seat
If the child in your child restraint system is in a very upright position, adjust the seat-
back to the most comfortable position.
If the seat belt shoulder anchor is ahead of the child seat belt guide, move the seat
cushion forward.
*2: Remove the head restraint if it interferes with your child restraint system.
*3: When using the left side seat for the child restraint system, do not sit in the center 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. 3 6 ) When you have to use a child restraint system
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).
