WarningBefore any work on the structure of a vehicle with on board electric energy (electric vehicle/hybrid vehicle), the vehicle must be isolated by an authorised technician
WarningObserve the safety and cleanliness recommendations
WarningObserve the precautions to be taken for the pre-tensioning components
WarningFor any paint retouching operation on a vehicle that has the STOP and START system requiring a paint booth, it is necessary to remove the central voltage retention device assembly (DMTC) if the temperature exceeds 80°C
WarningAny repair work carried out on a vehicle with on board electric energy (electric vehicle/hybrid vehicle) must be carried out by an authorised person
WarningAll of the stripped surfaces must be protected by means of the approved electrolytic rezincing process
WarningThe number of spot welds or strip welds necessary for the assembly of a new component must be identical to the number of spot welds or strip welds securing the original component

Replacement part preparation
WarningWhen cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection
Mark then drill 6 8 diameter holes for later plug welding
Prepare the mating edges and protect them using a weldable primer (index "C7")
NoteApply the weld-through primer on the internal faces of the panels to be welded
Cutting of the part on the body
Cut out the spot welds
Remove the engine compartment front panel support assembly
Cleaning and preparation of the body
WarningWhen cleaning the mating edges, use scouring wheels only to avoid damaging the anticorrosion protection
Prepare the mating edges and protect them using a weldable primer (index "C7")
NoteApply the weld-through primer on the internal faces of the panels to be welded
Adjustment
Position the engine compartment front panel support assembly (1) against the chassis leg end piece (4)
NoteCheck the adjustment of the engine compartment front panel support assembly (1) and of the chassis leg end piece (4) for later refitting of the front bumper frame (at "a")
Holds the part in position
Welding
WarningThe number of spot welds or strip welds necessary for the assembly of a new component must be identical to the number of spot welds or strip welds securing the original component
Weld with MAG plug welds
Grind the MAG plug welds
Weld with electric spot welds (at "b")
Sealing protection
Apply a phosphate-print layer on the zone laid bare
Painting, then spraying of the index "C5" product into the hollow sections in the repair zone
Additional operations
Refit the electrical harnesses and the components removed
Reinitialisation
Reactivate the pyrotechnic systems
WarningPerform the operations that are required following a reconnection of the ancillaries battery
Reconnect the ancillaries battery
