Rear View Mirrors
The.interior rear view mirror is an electrochromic unit that automatically da rkens to prevent glare from following vehicle
lights. This automatic function is selected by pressing the switch at the bottom of the mirror. Pressing the switch again
cancels this function. An LED then illuminates when automatic dipping is operative. The light sensing unit for the Night
Sentinel automatic lamp operating system is also incorporated in the mirror casing.
The door mirrors are cheater mounted, colo r-keyed units, remote electrically adjustable and heated. Adjustment of both
mirrors is carried out from the driver's door switchpack.A slider switch selects the mirror to be adjusted, and a disc switch
adjusts the selected mirror to the required position. Mirror ad justment can only be made when the ignition switch is in
position I or II or the driver's door is open, and the selector switch is moved from the central position. The door mirrors also
automatically darken under control of the electrochromic interior rear view mirror. Mirror heating elements operate on
selection of backlight heating.
Automatic dipping of passenger door mirror for kerb view when reversing, is fitted as part of the memory pack. With the
ignition switch in position II, the mirror selector switch in the left or right position and reverse gear selected, automatic
dipping is initiated by moving the mirror toggle switch rearwards and releasing. On receipt of the dip signal, the passenger
door mirror is driven downwards either 7 degrees, bottom of travel, or 4,5 to 5,5 seconds, whichever occurs first.
Subsequent rearward movement of the toggle switch achieves further dipping of the mirror in the same increments and
sequence. The mirror can be manu ally returned to the normal memorised positi on by moving the toggle switch forward with
reverse gear selected. The mirror will auto matically return to memorised position on deselection of reverse gear, or moving
ignition switch from position II.
Door mirror fold-back where fitted, to facilitate parking in conf ined spaces, can be initiated when the ignition switch is in
position I or II, the mirror selector switch is in the centra l position and vehicle speed is below 19 km/h (12 mph). Mirror
fold-back is then initiated by moving the toggle switch rear wards and releasing it. The door mirrors are returned to the
normal driving position by agai n moving toggle switch rearwards. There is no speed constraint on this operation. In the
event of a fold-back mirror becoming 'out of position' due to acci dental impact, it must only be re-positioned by initiating
the fold-back sequence.
Loss of power supplies will result in loss of mirror fold-back memory. In the event of such a memory loss with mirrors in the
normal position, fold-back will operate on second movement of the toggle swit ch. On loss of memory with mirrors in the
fold-back position, they will return to the no rmal position on next fold-back operation.
Bumpers
Each bumper comprises a beam mounted to the body via two strut assemblies, and a moulded polypropylene cover
incorporating side armatures and chrome plated blades. Each strut is secured to the BIW by three bolts and supports the
beam on a single bolt/height adjuster. The front bumper cover which is moulded to form a lo wer air intake for the cooling
pack, also incorporates left and right handed twin fog lamps, brake coolin g ducts. Side marker lamps fitted for some
markets serve only as reflectors for UK and Europe. A plastic undertray secured to the lower edge of the front bumper,
improves airflow and minimises the ingres s of road grime in that area. Standard bumpers have glass mat thermoplastic
(GMT) beams mounted on GMT struts. For certain markets, aluminium bumper beams are installed on menasco energy
absorbing struts. Whilst both types of front bumper provide a fu lly integrated 'soft front end' that satisfies bumper impact
requirements, the energy absorbing front and rear bumpers are further designed to withstand 5mph (8kph) impacts with no
visible damage sustained. Side markers/re flectors, and direction indicators are designed for ease of ac cess from the outside
of the bumper. For adjustment and bulb change, the fog lamps are accessed from th e bumper interior. The bumper covers
are body coloured and matched. Replacement covers are supplied complete with side armatures and are finished in primer
Trunk
The trunk houses the spare wheel, the battery, an electrical carrier containing electrical fuses, relays and modules and a
compact disc auto-changer attached to body bracketry. The trun k is fitted with push-fit liners to the sides and front inner
panel.The carpet covered floor is in two removable sections, one covering the spare wheel and wheel changing equipment,
the other covering the battery and electrical carrier. The front and rear edges of the floor board loca te in blocks on the fuel
tank backboard and the rear of the body , which provide two height settings to accommodate the difference in thickness
between the space saver and full sized spare wheels. A moulded finisher covering the rear of the trunk below the sill is
secured to the rear panel by tabs and fir tree fasteners. Finisher panels fitted over the rear lamp units provide for access
from the trunk. Finisher panels fitted to the rear lamp units provide trunk inte rior access to the lamps. The trunk lid
underside is fitted with a removable mo ulded liner and two trunk illumination light s. Trunk locking is based on a central
latch and striker, operated electrically through the central lo cking system by an adjacent actuator or by key in a barrel lock

located behind the trunk lid badge.
Occupant Restraints
Inertia reel seat belts with electronically controlled pre-tensioners are installed at the front seats. Supplementary occupant
restraint is provided for driver and front seat passenger by front airbags, and side air bags installed in the outer wing of
each front seat. Standard inertia reel type belts are fitted to all three rear seat positions. The front seat belts are provide d
with height adjuster units which are attached one to each of the 'B' posts. Where emergency locking retractor/automatic
locking retractor seat belts are provided, the belts have two operating modes.The inertia reel mode with emergency locking
retractor is for adult passenge r use only and operates to allow the occupant some freedom of tors o movement under normal
travel conditions.. The static reel mode which prevents belt payout and must be used when a ch ild seat is installed, is
activated by fully extending the belt to engage the ratchet me chanism,.then releasing the belt. Operation of the ratchet will
then be felt and the belt w ill become locked in that position. To revert to in ertia reel (adult passenger) mode, pay the belt
back into the reel to th e fully retracted position.
Body Structure
The XJ8 sedan body is produced in monocoque standard and lo ng wheelbase form. 70% of the body panels are zinc coated
to achieve optimum corrosion protection and a further 8% are constructed in high st rength steels to provide high torsional
strength and passenger impact protection.
Doors
Each front and rear door consists of a we lded, mild steel inner frame and an outer panel. The outer panel is welded to the
waist rail and cheater of the inner frame, then bonded and clinched to fo rm the door assembly. Cosmetic PVC bead is
applied to all clinch joints
Hood
The hood consists of one piece inner an d outer panels clinched and bonded toge ther, with cosmetic bead PVC sealant
applied to all clinch joints. The hood pivo ts at the front on two hinges each secured by bolts to the hood front underside and
the BIW front upper crossmember. Two gas struts secured to the hood by pi vot pins and snap-on couplings, support the
hood in the open position.
Trunk
The trunk lid is of similar construction to the hood, consisting of inner and outer panels clinched and bonded together and
PVC bead sealed. The trunk accommodates the spare wheel, the battery, an electrical carrier containing electrical fuses,
relays and modules and where premium ICE is fitted, a compac t disc auto-changer mounted on body bracketry. Carpet
covered trims line the trunk sides and front inner panel and a po lyurethane rear finisher is secured to the rear panel by
spring clips and fir tree fasteners.

two-section, removable trunk floor prov ides 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 e dges locating in blocks on the fuel tank
backboard and the rear of the body. The support blocks provide for two floor height settings to accommodate either a space
saver or full size spare wheel.A trunk seal retainer covers the re ar of the trunk below the sill. Finisher panels fitted to the
rear lamp units provide for trunk inte rior access to the lamps. The trunk lid underside is fitted with a removable moulded
liner and two trunk illumination lights. Two gas struts fitted between the inner wheel arches and trunk hinges support the
trunk lid in the open position. For some markets, a warning triangle is attached to a bracket on the trunk lid underside. The
trunk is locked by a central latch and stri ker operated by an adjacent electrical actuator, via the central locking system, or
by key operation of a barrel lock located behind the trunk lid badge.
