For our Car Seat Checks, the driver's seat is positioned for a 6-foot driver; in the iQ that left no legroom for a second-row passenger behind the driver. The front passenger sits farther forward, creating more legroom for the person sitting behind the front seat. We installed our child-safety seats behind the front passenger seat.
For the Car Seat Check, we use a Graco SnugRide 30 rear-facing infant-safety seat, a Britax Roundabout convertible child-safety seat and Graco high-back TurboBooster seat.
The front seats are adjusted to a comfortable position for a 6-foot driver and a 5-foot-8 passenger. The three child seats are installed in the second row. The booster seat sits behind the driver's seat, and the infant seat and convertible seats are installed behind the passenger seat. We also install the convertible seat in the second row's middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit. If there's a third row, we install the booster seat and a forward-facing convertible.
Here's how the 2012 iQ did in Cars.com's Car Seat Check:
Booster seat: We had to wedge our high-back booster into the backseat because the seating area is narrow. Once in, the booster fit fine. The seat belt buckles rest in a well in the bottom seat cushion. To use the buckle, you have to pull it up. It stays in place once it's up.
Convertible seat: The forward-facing convertible fit well in the iQ after we removed the head restraint; there was enough room for a child's legs. The rear-facing convertible fit in the backseat, but the front passenger seat had to be moved all the way forward. The front passenger fit in the front seat but wasn't comfortable.
Editor's note: For three car seats — infant-safety seat, convertible and booster seats mdash; to fit in a car, our criterion is that a child sitting in the booster seat must be able to reach the seat belt buckle. Parents should also remember that they can use the Latch system or a seat belt to install a car seat.
