your vehicle, you must have the tank
drained and refilled with the correct
fuel before you star t the engine.

Misfuel prevention (diesel)*Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of e

Located
  in   the   filler   neck,   the   misfuel   prevention   device   appears   when   the   filler   cap   is   removed.
When
