■Installing child restraint system using a seat belt 
Install the child restraint system in accordance to the operation 
manual enclosed with the child restraint system. 
If the child restraint system on hand is not within the “universal” cat- 
egory (or the necessary information is not in the table), refer to the 
“Vehicle List” provided by the child restraint system maker for vari- 
ous possible installation positions, or check the compatibility after 
asking the retailer of the child restraint system. ( P. 60, 61) 
If installing the child restraint system to the front passenger seat 
is unavoidable, refer to P. 56 for front passenger seat adjustment. 
If the head restraint interferes with the child restraint system 
installation and the head restraint can be removed, remove the 
head restraint. Otherwise, put the head restraint in the upper 
most position. ( P. 343) 
Run the seat belt through the 
child restraint system and 
insert the plate into the 
buckle. Make sure that the 
belt is not twisted. Securely 
fix the seat belt to the child 
restraint system in accor- 
dance to the directions 
enclosed with the child 
restraint system. 
If your child restraint system 
is not equipped with a lock- 
off (a seat belt locking fea- 
ture), secure the child 
restraint system using a lock- 
ing clip. 
After installing the child restraint system, rock it back and forth to 
ensure that it is installed securely. ( P.  6 9 )

■Removing a child restraint system installed with a seat belt 
Press the buckle release button and fully retract the seat belt.
When releasing the buckle, the chil d restraint system may spring up due 
to the rebound of the seat cushion. Release the buckle while holding 
down the child restraint system. 
Since the seat belt automatically reels itself, slowly return it to the stow- 
ing position.
■ When installing a child restraint system 
You may need a locking clip to install the child restraint system. Follow the 
instructions provided by the manufacturer of the system. If your child restraint 
system does not provide a locking clip, you can purchase the following item
from any authorized Toyota retailer or Toyota authorized repairer, or any reli- 
able repairer: Locking clip for child restraint system  
(Part No. 73119-22010)
WARNING
■ When installing a child restraint system 
Observe the following precautions. 
Failure to do so may result in death or serious injury. 
● Do not allow children to play with the seat belt. If the seat belt becomes 
twisted around a child’s neck, it may lead to choking or other serious inju- 
ries that could result in death. If this occurs and the buckle cannot be
unfastened, scissors should be used to cut the belt. 
● 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. 
● When a junior seat is installed, always ensure that the shoulder belt is 
positioned 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. 
● Follow all installation instructions provided by the child restraint system 
manufacturer.
