This model year range is relatively unchanged from the original – except now there are only 4 lower anchors (instead of 5) and the vehicle head restraints are slightly different in shape.
Straight tether straps should be routed over the head restraints, and V-shaped tether straps should go around the head restraints.
The lower anchors being high in the seat crack are problematic for rigid LATCH seats and some seats using LATCH straps.
The 3rd row rear-facing seats remain as an option – and are for children who are at least 37 inches tall and short enough that the top of the child’s head can not contact the vehicle and who weigh between 35-77 pounds.
In this model, there were 5 lower anchors – but installing a car seat in the center with LATCH is very problematic as it will take up the driver & center positions, and due to the bump in the seat cushion will likely not yield a secure installation. In this vehicle, if installing a car seat in the center, we recommend using the seat belt (and obviously the top tether too if it is a forward-facing car seat).
Note: the Model S was changed mid-year during 2014, so some 14’s have 5 lower anchors as shown below, and others have 4 lower anchors (and no center LATCH) as shown above.
The 3rd row rear-facing seats are an intriguing option – and are for children who are at least 37 inches tall and short enough that the top of the child’s head can not contact the vehicle and who weigh between 35-77 pounds.
