That contravened article 22.5 of the sporting regulations, which says: "A driver who abandons a car must leave it in neutral or with the clutch disengaged, with the ERS shut down and with the steering wheel in place."
No action has been taken against Vettel over the matter.
When asked by Autosport why he took the wheel with him, Vettel replied: "It was a sort of reflex.
"I saw Pascal was stopped and I couldn't get the steering wheel back on because the steering column was completely turned.
"Obviously the car was damaged. I put it in the seat, and it was reflex - sometimes they open the track to spectators, so I thought that's the only loose bit.
"Because I couldn't put it on I thought I might as well take it with me just to make sure.
"You don't want to lose a steering wheel. Was it necessary? Probably not."
