Graco 4EVER EXTEND2FIT Instruction Manual page 77

Graco allows the securing of the car seat with
LATCH in the booster mode. The child still MUST BE
SECURED with the vehicle lap/shoulder seat belt.
LATCH can be used in the booster mode regardless of
the weight of the child up to 100 lb (45 kg).
Verify the following before using LATCH in the booster
mode:
•The LATCH connectors DO NOT interfere with any
vehicle seat belts or buckles.
If the LATCH interferes with the vehicle seat belts or if the chosen seating position
does not have LATCH, you MUST store the LATCH strap. Store the LATCH strap by
pushing in on the red buttons on the connectors and attach to the plastic bars as
shown. Store the top tether strap as shown. Always secure car seat with LATCH or
a vehicle seat belt, even when unoccupied. In a crash, an unsecured car seat can
injure passengers.
