Reclining Seats (2500/3500/Mega Cab Models)
The recliner handle is on the outside of the seat cushion.
Pull up on the handle, as shown, to release the seatback
and adjust for comfort.
WARNING!
You can be seriously, even fatally, injured riding in a
seat with the seatback reclined. Do not ride with the
seatback reclined so that the shoulder belt is no
longer resting against your chest. If you ride in this
position, the shoulder harness will no longer be
restraining you. In a collision you could slide under
the seat belt and receive serious or fatal injuries.
Recline in a seat only when the vehicle is parked.
