Effective immediately all current models of Diono convertible seats (R100, R120, RadianRXT, Olympia, Pacifica & Rainier) and Diono boosters (Monterey, Cambria, & Solana) can now be used in Ford vehicles that have inflatable seatbelts! This allowance is retroactive to previous Diono and Sunshine Kids Radian and Monterey models.

Currently, inflatable seatbelts are an optional feature in the Ford Explorer, Edge, Flex, Fusion and F-150 as well as in Lincoln’s MKT, MKX and MKZ models. Read more about our experience with inflatable seatbelts in our Ford Explorer Review. This new allowance from Diono does NOT include the inflatable seatbelts found in some Mercedes-Benz vehicles.

If you own a Ford or Lincoln vehicle with inflatable seatbelts, or if you are a CPS Technician working in a Ford/Lincoln vehicle that has this technology, please make sure you understand how to lock this particular type of seatbelt before attempting installation of ANY harnessed carseat.

ford-inflatable-seatbelt-upper-elr-retractorThe Ford inflatable seatbelt system uses 2 retractors which is very unusual. One retractor at the top of the shoulder belt, where you normally expect to find a retractor (pic right) and a second retractor (pic below) is near the floor at the end of the lap belt portion of the lap/shoulder belt. When installing ANY approved harnessed seat with these seatbelts you must switch the retractor on the lap belt portion of the seatbelt to locked (ALR) mode. The retractor at the top for the shoulder belt is not “switchable” – it is ELR only, meaning that section of the seatbelt will only lock during a crash or under emergency conditions. ELR retractors don’t do you any good when it comes to a harnessed carseat installation (boosters are a different story) so you MUST lock the lap belt portion of the seatbelt by “switching” the bottom retractor to locked mode. Switching a switchable retractor to locked mode is achieved by pulling the webbing of the seatbelt all the way to the end. When the webbing starts to retracts, you will hear a ratcheting sound and you will notice that the belt webbing goes in but won’t come out in this locked mode. Read the vehicle’s owners manual for clarification and more specific details.


If using an inflatable seatbelt to secure a child in a Diono booster seat, you don’t have to worry about any of this. Just route the seatbelt properly and buckle.
