Using the Booster Seat
WARNING!
• DO NOT use this booster seat without the backrest unless the booster seat
will be properly installed in a vehicle seat with a headrest.
• ONLY use this booster seat without the backrest if proper vehicle belt
positioning can be achieved. Proper positioning is achieved when the vehicle
belt’s shoulder section crosses the chest and center of the child’s collar bone.
• ALWAYS use the vehicle’s lap-and-shoulder belt system when using this
booster seat without the backrest.
Place the booster seat base in a seating
position equipped with a vehicle lap-shoulder
belt and headrest. Refer to page 7 for Vehicle
Seating Positions. (Fig. A)
Pull the vehicle belt from the retractor,
positioning the lap belt under both armrests
and in front of both color-coded belt guides,
then latch the vehicle belt buckle. (Fig. B)
Ensure the buckle is secure by gently pulling
on it.
Adjust the vehicle-belt’s shoulder section so
that it crosses the chest and center of the
child’s collar bone. (Fig. B)
Straps should be tight and not twisted. All
slack should be removed from lap and
shoulder portions of the vehicle belt to ensure
a snug fit.
