The Peg-Perego Primo Viaggio SIP 30/30 infant car seat can be used for infants up to a weight of 30 lbs. or a height of 30 inches. You can install the car seat with or without the base, but Peg-Perego strongly recommends using the base to avoid installation mistakes if you decide to use the car seat as a carrier. The Primo Viaggio can only be installed rear-facing, and the baby should always be buckled into the car seat before use.
Installing Base with LATCH
Remove car seat from its base.
Place the base rear-facing in the desired position in the back seat of the car. The pointer on the level indicator should be in the green area. Adjust the knob so that level pointer is in green area.
Press the gray button on the anchor latches on the sides of the base to loosen. Press the red button on top of the latch and pull the latch to remove it from its housing.
Check your vehicle manual for LATCH anchor locations in the rear seat. The anchors are between the vehicle seat and the back of the vehicle seat. LATCH, or Lower Anchors and Tethers for Children, are available in most cars manufactured after 2003 and make installing a car seat easier and faster. Use LATCH or a seat belt to install car seat, but never both.
Press the latches onto LATCH anchor bars between the back and bottom of the vehicle seat. Listen for a click so you know the latch is properly attached. Be sure the strap between the two latches is flat against base.
Pull the free end of the latch strap while pressing down on the base with your knee to tighten. Be sure the level indicator pointer is still in the green area. The base should not move more than 1 inch from side to side if the strap is properly tightened.
Installing Base with Seat Belt
Remove car seat from base.
Place the base rear-facing in the desired position in the back seat of car. The pointer on the level indicator should be in the green area. Adjust the knob so that the level pointer is in green area.
Pull the lap belt through the slots on the base and buckle the seat belt.
Pull the shoulder strap to tighten seat belt while pressing down on base with your knee. The base should not move more than 1 inch from side to side. Be sure the level indicator pointer is still in the green area.
Installing With a Locking Clip
Hold the shoulder strap and lap belt together just above the buckle after positioning the car seat appropriately on seat and threading the lap belt through the slots on base.
Unbuckle the belt, continuing to hold the lap and shoulder belts together.
Thread both shoulder and lap belts together through the locking clip so that the belts go over the center portion of the clip.
Buckle the seat belt again, leaving 1/2 inch of space between clip and latch.
Installing Car Seat onto Base
Hold the car seat by the handle and position it rear-facing over the base.
Press the car seat into base until you hear a click and the car seat does not move around in the base.
Look at the level indicator to be certain that base is still level.
Press the round buttons on either side of the handle bar to raise handle of car seat out of carrying position toward the head of the car seat. Never leave the handle in the carrying position while driving.
Removing Car Seat from Base
Press the buttons on either side of handle to put the handle into carrying position.
Place one hand on the top of the seat back.
Pull up on the center of handle to remove.
Installing Car Seat Without Base
Place the car seat on vehicle seat in a rear-facing position.
Press the gray buttons on either side of the handle and push the handle to the top edge of the car seat.
Adjust the seat so that it is parallel to the ground. You may use a pool noodle or rolled towel at the vehicle seat crease if necessary. The red line on the seat must be parallel to the ground.
Slide the lap belt through the slots on the seat.
Buckle the seat belt.
Pull the shoulder strap while your knee presses the seat down to tighten. Be sure the red line is still level with the ground. Be sure the seat does not move more than 1 inch side to side.
Buckling Baby into Car Seat
Put your baby into car seat with her back against the back of the seat.
Pull shoulder straps over baby's shoulders with arms through the straps. Be sure that the straps are not twisted.
Buckle the two latch plates until they click, pulling to assure that they are fastened. Press the red button and pull the latches upward to unfasten.
Latch the chest clip. The chest clip should be at armpit level. Squeeze the buttons together on the chest clip to unfasten it.
Pull the adjuster strap at the bottom of the seat to tighten the harness. There should be one finger width between the harness and the baby's collar bone. Press and hold the adjuster button down and pull the top harness up to loosen. The harness should be snug without pressing into the baby or sagging.
Adjusting Car Seat Straps
Push the button on the top of the back plate of the car seat.
Pull the plate to move shoulder straps to appropriate position.
Adjust the shoulder straps to be just below baby's shoulder level. The top of the baby's head should not be above the car seat.
Be sure your car is parked on level ground when installing the car seat.
Have your car seat checked by a professional to ensure proper installation: Find a car seat inspector by searching your zip code at Seatcheck.org or calling your local police station.
Always check your vehicle manual for additional information regarding car seat installation and positioning.
If your lap/shoulder belt does not lock, you will need to follow the directions for use of the locking clip.
Always check to be certain the car seat straps are not twisted.
