13.2.1 Doors, Description
Doors are of welded, mild steel frames welded to the door panels; sponge rubber primary and secondary seals are
mounted on the doors. Internal insulation is provided by a foam water shedder attached to the door by press fitting and doublesided adhesive tape.
Front and rear door armrests are attached to supports riveted to each door frame; the attaching screws are fitted
with access covers. Upper and lower trim pads and a door pocket are attached to each of the doors by clips and screws. multi-plug connectors are used to provide a means of connecting the guard lamps, window lift switches and loud- speakers, external mirror and regulator (front doors only), which are housed within the doors.
Central locking is provided subject to market variations: Dead Locking for UK
/ Europe and Driver only unlock for N America. Door locks are eight disc, bayonet fixing, barrels with integral lock / unlock switches. Keys include ‘in-key’
transponders which are programmed to the vehicle via the Jaguar Diagnostic System also operate the engine immobi
- lisation system.
CAUTION: When removing the door panel water shedder, a foam membrane attached to each door panel by a com- bination of pressfitting (upper area) and bydouble-sided tape (bottom area), it is important that the shed- der is refitted correctly to maintain the water seal.
It is advisable not to disturb the bottom (taped) portion of the water shedder unless absolutely necessary
- it is possible to unclip the top of the shedder and bend it over to gain access to the inner panel.
If
it is necessary to disturb the bottom attachment, eg to remove the water shedder from the door panel,
the existing water shedder must be discarded and a new one fitted to ensure that the seal is maintained.
On refitting, the new water shedder should be pressed onto the door panel at the top and then the adhes- ive tape backing strip peeled off to enable the shedder to be pressed home at the bottom.

Localized stains caused by accidental spillage may be one of three types:
0 Water based stainscaused byfoodstuffs,starches, sugars, soft drinks,fruit stains, washable inketc. These stains
adhere readily to the pile and do not respond to vacuum cleaning. They are best removed immediately using
the procedure detailed below.
0 Oil /grease based stains caused by spillage or other contamination by butter, grease, hand cream, ball point pen
ink, crayon, lipstick etc.
0 A combination of both these types.
Spot Cleaning - Localized Stains
To remove water based stains:
. Blot up liquids and /or scrape off semi-solids using a spatula.
. Sponge the affected area with clean luke-warm water. Use a clean, damp, undyed, cotton cloth to absorb as much

= Rinse with clean, warm water, taking care not to over-wet the carpet.
Absorb excess moisture by laying dry, undyed cloths or white paper towels over the moist carpet under light pres-
. When the carpet is thoroughly dry, vacuum clean the area to lift the carpet pile.
CAUTION: When liquids are applied to the pile, use only a clean cloth or sponge. Do not apply liquids directly to the
carpet - when attempting to remove stains, blot the pile as heavy rubbing can destroy the yarn structure of the carpet.

sure; replace when necessary.
To remove oil /grease based stains:
. Using a suitable aerosol containing solvent loaded with absorbent powder, spray the affected areas of the carpet.
= Allow the solvent to evaporate and remove the powder containing the grease by using a vacuum cleaner or brush.
m:
CAUTION: Solvents must only be used in well-ventilated areas where naked lights and smoking are prohibited.
The solvent loosens the grease from the fibre and the powder then absorbs the grease-carrying solvent.
Neat solvent, eg dry cleaning
fluid, may be used, but should be used sparingly from a clean white cloth.
To remove stains which are a combination of oil and water based contamination (usually resulting from food or drink):
. Treat combination stains as for water based stains.
. Allow to dry out.
. Treat as for grease based stains.

13.8 SEATING AND SEAT BELTS
13.8.1 Seating, Description
The front seats are available in a range of materials consisting of sculptured fabric / leather, leather, sports cloth / leather, embossed leather / leather and autolux. Both seats are available as 'manual', ie manually adjustable with elec- tric rise and fall, manual height adjustment headrests, 'power', ie 12-way electric adjustment, 'power with memory', ie memory controlled, 12-way electric adjustment of seat, steering column and exterior rear view mirrors and 'heated',
ie with integral heating.
Front seats are based on a non
-handed, one-piece frame which includes cushion and squab frames and seat adjuster
mechanisms. The seat switchpacks (powerseats) are fitted to the outboard side of driver and passenger seats; on 'man- ual'seats, the seat height adjustment switch is similarly located. Seat control modules SCMs are contained within the
seat assemblies. The seats are secured through four mounting points to the vehicle floor.
Rear seats are of the bench type with
full width removable cushion and individual seat squabs.
Electrical components installed on the heel board below the rear passenger seat are protected
by two covers secured
by two locating brackets on the floor and by two latches on the cover. The latches are released by pushing down on
the two recesses in the top edge of the cover.
