Tips and Troubleshooting

Problem: The harness cannot be adjusted to its full height.
Possible Solution: Check the seating position where the child seat 

is installed. The vehicle head restraint may obstruct the path of the 

child seat harness height adjuster. Remove or raise the vehicle head 

restraint and try adjusting the harness height again.
Problem: The harness is hard to adjust.
Possible Solution: The yoke may be caught on the Versa-Tether

®

 

webbing or other component of the child seat. Remove the obstruction 

and try adjusting the harness again. Always store the Versa-Tether in 

the pouch provided when not in use. When the Versa-Tether is in use, 

always secure excess webbing in the elastic strap. See pages 26 – 29.
Possible Solution: The vehicle seat back may hinder harness 

adjustment. Ensure the child seat base is flat on the vehicle seat.
Possible Solution: The harness may be at maximum or minimum 

height, the harness may be too tight to adjust, or the child’s weight 

may be pressing against the head restraint. Check for and correct all of 

the above where necessary and try adjusting the harness again.
Problem: The adjuster strap is fraying at the sides.
Possible Solution: Pull the harness adjuster strap up and away from 

the child seat to tighten. Do not pull sideways. Doing so may cause the 

harness adjuster strap to fray at the sides. See page 57.
Problem: The buckle will not fasten with a click after each tongue 

is inserted.
Possible solution: There may be debris in the buckle mechanism. 

Clean the buckle as shown on pages 64 – 65 and try fastening the 

buckle again.
