Description and Operation

Body Front
The thermoplastic front bumper incorporates chromed plastic upper quarter blades and where fitted, chromed covers for the headlamp powerwash jet assemblie s. The bumper lower air intake aperture is specifically profiled to achieve optimum
cooling of the AJV8 engine. A splitter vane installed in the lowe r air intake, is chromed on Daimler and Vanden Plas vehicles
and colour-keyed on all other models. An ov oidal sidemarker lens or reflector is installed in each side of the bumper cover.
The low profile plastic radiator grill surround is colour-keyed on Sport and XJR mo dels, chromed and fluted on Daimler and
chromed plain on all other models .A Jaguar 'growler' badge is fitted in the upper central positi on of the grill surround. For
certain markets, a spring-loaded chromed Ja guar 'leaper' mascot is installed centrally on the front of the hood. Radiator
grills are chromed mesh on the XJR, dark grey vertical vanes on the Sport, and chromed ve rtical vanes on all other models.
Body Sides
For certain markets, a Jaguar 'l eaper' badge fitted in place of the direction indicator side re peater, is surface mounted in a
shallow recess on the rear of each fro nt fender. Three-piece colour-keyed body side mouldings surface mounted on the
lower section of each door and front fender align with bumper upper extremities. A brightwork inset is incorporated in the
upper edge of side mouldings on Daimler and Vanden Plas models. On Daimler models, a 'Daimler' script badge is mounted
on the upper section of the B post. A 'V8' badge is fitted in the same position on all other models.
All models have coachlines painted on th e front fenders, the doors and rear fender s. Sport and XJR models have upper and
lower coachlines 1.5mm an d 3mm wide respectively, XJ8 has a 1.5mm single upper coachline and all other models have a
single upper coachline 3mm wide.
Body Rear
The themoplastic rear bumper also inco rporates chromed plastic upper quarter blades and ovoi dal sidemarker lenses or
reflectors. The trunk lid trim is colour-keyed on Sport and XJ R models, chromed fluted on Daimler and chromed plain on all
other models.
With the exception of Daimlers, the trunk lid rear carries a 'Jaguar' badge on the LH side. Daimlers carry a script 'Daimler'
badge in the same location. On th e RH side, Jaguar models carry an 'XJ8', '3.2 Sport', '4.0 Sport', 'Sovereign 8', 'XJR', or
'Vanden Plas' badge as applic able. Daimlers carry a 'V8' badge in the same position.

cooling duct.
The windshield washer is operated by pressing the button at the end of the wiper control stalk switch. Pressing and
releasing the button operates the washer for 1 to 1.4 seconds and the wiper completes three sweeps. An optional drip wipe
function adds a further sweep of the wiper after a 4 second delay, to clear residual fluid from the windshield. If the button is
held depressed, the washer and wiper will operate continuous ly for up to 20 seconds. When the button is released, the
wiper will again complete three further sweeps.
Headlamp Powerwash

The headlamp powerwash system incorporates a chromed twin nozzle assembly mounted on the chromed bumper blade
immediately in front of each pair of he adlamps. Each nozzle assembly is connected via snap fittings to a powerwash pump
mounted adjacent to the windshield wash pump on the rear face of the washer fluid reservoir.The powerwash system
operates in conjunction with the windshield washers when the ignition switch is in position II and the headlamp switch is in
the dip or main beam position. When powerwash is initially activated, a wash cycle commences, consisting of two 400 ms
pulses separated by a three second delay. If powerwash is still selected on completion of this cycle, it will continue to
operate at the same frequency for a maximum period of 20 se conds. To conserve washer fluid, headlamp powerwash will
only function on every sixth operation of the windshie ld wash switch.When the 'WASHER FLUID LOW' message is
illuminated, the windshield washer will continue to operat e for a limited period but the headlamp powerwash will not
function until the fluid level is restored.
Rain Sensing System
The rain sensing system installed form so me markets, provides automatic wiper operation when rain is detected on the
windshield. The system detects differing le vels of rainfall and varies wiper operation ranging from intermittent to maximum
continuous, to suit prevailing requirements.
The system which is brought into operation by selecting AUTO on the wiper control switch bezel, does not preclude normal
manual control of wiper operation.
The system consists of a rain sensor, an electronic control module and a dedicated wiper control switch.
The rain sensor is an optical transducer that is sensitive to changes in infra-red light penetration of the windshield created
by the refractive effects of water drople ts. The sensor elements consist of two groups of light emitting diodes which
alternately project infra-red light onto th e windshield and a photo-diode that receiv es resulting reflections from the glass. A ll
of the infra-red light is reflected back from a moisture-free windshield, resulting in a contact 5V output signal from the
sensor and no wiper activation. Rain falling on the light sensing area of the wi ndshield results in refraction and diffusion of a
proportion of the projected light with a corresponding imbalance of light received by the photodiode. This results in pulsed
outputs from the sensor, the frequency and duration of which are directly proportional to the number and size of water
droplets respectively. These pulses together with wiper switch position signals are received by the sensor control module
and processed to mimic column switch gear operation. In this recognisable form, signals are input to the body processor
module (BPM) where they are interprete d as normal wiper operation requests.

Body Structure
Introduction
The standard wheelbase Jaguar sedan has a unit construction monocoque body structure with bolt-on front fenders and
welded rear fenders. The doors feature lif t-off hinges and welded drop-glass frames.
Constructional Steel Classification
BODY ALIGNMENT
The Body Dimensions Plan, and Body Dimensions Side View, provide specified BIW dimensions to facilitate damage
assessment and location of replacemen t parts. These dimensions must be strictly applied when used for damage
assessment, component location or post repair verification.
• NOTE: The right-hand side is always looking towards the front, from the rear of the vehicle.
The nominated plan view master datums are on the right-hand side of the body with the left-hand datums dimensioned
from them. Right-hand datums must therefore be known to be correct before any other cross-car dimensions are checked.
Datum location, Example
The Front Master Datum (front crossmember rear mounting at the inner face of the main floor RH longitudinal) is nominally
359,5mm to the right-hand side of the body center line. The LH side fron t datum is measured 717,0 / 721,0mm from the
RH. Refer to the Body Dimensions Plan.
Expressed as a true posi tion in three planes, the front master datum is:
