Your vehicle may have a low-back or high-back air suspension seat. There are two ways you can adjust the seat.
The suspension seat height adjustment lever is located on the front inboard side of the seat.
To adjust the height of the air suspension seat, pull the lever up to inflate. Push the lever down to deflate.
The seat cushion can also be raised or lowered.
The seat cushion height adjustment handle is located underneath the front of the seat.
To adjust the height of the cushion, lift the handle up and pull it forward. You can choose between two settings.
If your vehicle has this feature, the handle is located on the outboard side of the driver's and passenger's seats.
Move the handle down to reduce any backslap experienced while in tractor/trailer operation or while operating a dump truck application.
