Interior Trim and Ornamentation - Interior Trim
Description and Operation
Carpets
The passenger compartment carpet is a one piece moulded constr uction with integral sound deadening material, heel mats
and driver's footrest. The carpet is attach ed to the vehicle floor by plastic clips fitted below the door treadplates. Removal of the carpet necessitates re moval of the front seats, lifting of the centre console rear extens ion and removal of the heelboard
carpet.
Fascia
The full width, slush moulded, soft feel PVC fascia is mounted on an injection moulded armature and is faced with wood
veneer. In addition to the air conditioning and central, outer and demisting vents, it accepts instrument packs dedicated to
market requirements and a centrally mounted analogue clock.
Doors
The one-piece door casings are trimmed in UEV to match the seating, with wood veneer at the waistline and a carpet insert
at the front lower corner. Each casing is secured to the door inner panel by fir tree press fast eners along the lower section,
two armrest fixings at the centre and vene er panel dowels and fixings at the top. The armrests which are common to front
and rear doors, are trimmed in matching leather or UEV according to specification. The door switchpacks, dedicated to
driver and front or rear passenger, are in corporated in the armrests. A speaker is in stalled in the lower section of each door
and a tweeter is incorporated behind each interior door handle escutcheon. Where premium ICE is fitted, the front tweeters
are installed in the upper A posts.
A, B, C and D Posts
On each side,a grained UEV finisher trimmed to match the headlining is secured to the 'A' post and cantrail by fir tree
fasteners locating in BIW apertures. The upper 'D' post finisher is trimmed and secured in the same manner. The single
piece'B/C' post finishers, also finished in grained matching UEV, each have a front se at belt exit aperture and are secured to
the BIW by four spring clips and two fir tree fasteners.
Headlining
The one-piece headlining consists of a 6mm thick polyurethane foam membrane covered with suede effect knitted polyester. The headlining is secured to the BIW roof by body tangs, the roof console, sun visors, combined grab handles and coat
hooks, the cantrail finishers and where fitt ed, the sliding roof finisher and clips.
Trunk
Carpet covered trims line the trunk and are secured by fir tr ee fasteners to the sides and front inner panel. The carpet
covered, two-section, removable trunk fl oor provides access to the spare wheel and wheel changing equipment, the battery
and electrical carrier. The floor board rests on the spare wheel, with the front and rear edges locating in blocks on the fuel
tank backboard and the rear of the body. The support blocks provide for two floor he ight settings to accommodate either a
space saver or full size spare wheel.A moulded finisher covering the rear of the trunk below the sill is secured to the rear
panel by tabs and fir tree fasteners. Finish er panels fitted to the rear lamp units provide trunk interior access to the lamps.
The trunk lid underside is fitted with a removabl e moulded liner and two trunk illumination lights.
