Child seat belt usage
The seat belts of your vehicle are principally designed for persons of adult
size.
Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle's seat belt. (P. 121)
When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 74 regarding seat belt usage.
Replacing the belt after the pretensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not activate for the second or subsequent
collisions.
Seat belt regulations
If seat belt regulations exist in the country where you reside, please contact
any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, for seat belt replacement or installation.
CAUTION
Observe the following precautions to reduce the risk of injury in the event of
sudden braking, sudden swerving or an accident.
Failing to do so may cause death or severe injury.
Wearing a seat belt
Ensure that all passengers wear a seat belt.
Always wear a seat belt properly.
Each seat belt should be used by one person only. Do not use a seat belt
for more than one person at once, including children.
Lexus recommends that children be seated in the rear seat and always use
a seat belt and/or an appropriate child restraint system.
Do not recline the seat any more than necessary to achieve a proper seat-
ing position. The seat belt is most effective when the occupants are sitting
up straight and well back in the seats.
Do not wear the shoulder belt under your arm.
Always wear your seat belt low and snug across your hips.

CAUTION
SRS airbag precautions
The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too
small to use a seat belt should be properly secured using a child restraint
system. Lexus strongly recommends that all infants and children be
placed in the rear seats of the vehicle and properly restrained. The rear
seats are the safest for infants and children. (P. 121)
Do not sit on the edge of the seat or
lean against the dashboard.
Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
Do not drive the vehicle while the
driver or passenger have items resting
on their knees.

Child restraint systems
Points to remember
Studies have shown that installing a child restraint on a rear seat is
safer than installing one to the front passenger seat.
Choose a child restraint system 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. 130)
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
conforms to the regulation “ECE No.44”.
Types of child restraints
Child restraint systems are classified into the following 5 groups
according to the regulation ECE No.44.
Group 0: Up to 10 kg (22 lb.) (0 - 9 months)
Group 0
+: Up to 13 kg (28 lb.) (0 - 2 years)
Group I: 9 to 18 kg (20 to 39 lb.) (9 months - 4 years)
Group II: 15 to 25 kg (34 to 55 lb.) (4 years - 7 years)
Group III: 22 to 36 kg (49 to 79 lb.) (6 years - 12 years)
Lexus strongly urges the use of child restraint systems.
