DESCRIPTION AND OPERATION
Doors
General
The door structure and skins are manufactured from aluminium alloy and are fitted with an impact resistant plastic
panel, finished in the body colour scheme, bolted to the lower external door skins.
The doors are attached to the door posts by two hinges. A door brake, with a metal retaining strap, is fitted between
the door and body frame to restrict the angle that the doors open.
Structurally, the difference between the front and rear doors is the extruded aluminium alloy Side Impact Protection
bar fitted to the front doors. The rear doors have, in addition to the window, a fixed quarter light.
The external door handles are bolted to the door structure and are accessed by removing the door trim casing. The
rear doors are each fitted with a manually operated child protection safety lock.
Child Protection Safety Lock
Fitted within the door structure, is the window regulator and glass, door locking mechanism , door wiring harness and
speakers. A moulded foam sound insulation panel, secured with a non-curing sealant, is fitted between the inner door
skin and trim casing. Between the door actuator and lock is a bowden cable, protected by an insulated sleeve. The
audio system, electric windows and door locking system are serviced by an electric wiring harness.
Trim Casing
The trim finish is dependent on the vehicle option level, either colour matched to the vehicle interior trim or leather
finished.
The trim casings are secured by screws and retaining studs. A moulded sound insulation panel is attached to the door
internal structure with a non-curing sealant.
All four doors have speaker grilles integral with the door trim, a switch to operate the door window mechanism, a
recessed sill lock button, arm rest and door handle.
The driver's door trim casing is fitted with a switch pack linked to the Body Control Unit (BCU) via the P-Bus. This
controls all four windows, and includes an isolation switch for the rear door windows, the door mirrors and the central
locking system.
In addition to the side protection bars, to protect the front seat occupants, a side impact air bag is stowed in the front
trim casings.
