Graco allows the securing of the car seat with UAS system in the
booster mode. The child still MUST BE SECURED with the vehicle
lap/shoulder seat belt. UAS can be used in the booster mode
regardless of the weight of the child up to 45 kg (100 lb).
Verify the following before using UAS in the booster mode:
• The UAS hook DOES NOT interfere with any vehicle seat belts or
buckles.
If the UAS interferes with the vehicle seat belts or if the chosen
seating position does not have UAS bars, you MUST store the UAS
strap. Always secure car seat with UAS or a vehicle seat belt, even
when unoccupied. In a crash, an unsecured car seat can injure passengers.
4. Extend the UAS Strap.
For easier installation, extend the UAS strap to its
maximum length by pressing the grey button and
pull out on the strap.
