You have an infant or toddler, and you own a rear-facing infant car seat.
Because your car was built before 2002, when the LATCH system became standard in every vehicle, you must install the infant car seat using your vehicle’s seat belts.
If possible, install the car seat in the center of the back seat, the safest point in case of crashes.
You’ll attach the seat base by threading the combination lap/shoulder belt through the lower belt path on the car seat base.
Make sure the car seat reclining level meets the manufacturer’s specifications.
Consult your vehicle owner’s manual to make sure you’ve properly engaged the seat belt locking system. Follow the seat manufacturer’s instructions to get a tight fit.
Then, attach the rear-facing carrier to the base, placing the handlebar in the position suggested by the car seat manufacturer.
