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:

• NOTE: The depth of the glass and thus the thickness of the ad hesive, is controlled by the screen rubber contacting the
body flange.
Adhesive Application

Key to Adhesive Application Drawing
Adhesive Curing
The specified adhesive cures by exposure to moisture (not by heat). Cure times may vary considerably dependent upon
ambient humidity levels. Initial 'chill off' will occur within 1 to 4 minutes ( dependent upon the application temperature and
rate of cooling), after which the screen must not be moved.
BUMPER REPAIR\RENEWAL
Bumper Description
Each bumper comprises a beam mounte d to the body via two strut assemblies and a moulded polypropylene cover
incorporating side armatures and chrome plated plastic upper trims. The front bumper cover which is moulded to form a
lower air intake for the cooling pack, also incorporates twin fog lamps, brake cooling ducts and side marker lamps or
reflectors (dependent upon market). A plastic undertray secured to the lower edge of the front bumper and the BIW
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.
Bumper Cover Repair
1Fitted condition
2Bead application

Prior to commencing any work, bumper damage should be assessed for repairability and categorized in accordance with the
following guidelines. Bumper covers that are torn or holed are not repairable and must be discarded.
CAUTION: Cosmetic appearance must no t jeopardise safety. No attempt must be made to repair bumper covers
damaged beyond category three. Damage of this extent will compromise the protective performance of the cover and it
must be renewed. The thermo-s etting nature of the cover material, preclude s the repair of splits by heat or welding
techniques.
Repair Materials
Repair of accepted damage for categories 2 and 3 may be carried out using 3M '5900 FPRM' (Flexible part repair material)
or Kent Industries 'Urepatch'. Repair product manufacturers' recommendations an d procedures must always be strictly
followed.
Bumper Cover Refinishing
The paint refinishing system must be approved by Jaguar Cars Ltd., and be appropriate for polyurethane substrate
application. It is essential that the fini shing clear lacquer includes a plasticising ingredient (mixed to the manufacturer's
recommendation) that will achieve the 'semi-fl ex' condition of the factory finished item.
Bumper Cover Support
Exposure to heat decreases bumper cover rigidity. Covers removed for repair mu st therefore be supported to prevent
distortion and sagging during the paint curing process. Where the original bumper cover has been repaired, the beam will
provide sufficient support for the centre section. It is recommended that the side armatu res are supported as they would be
on the vehicle. If a new cover is required, the beam may be temporarily fitted to provide the necessary support during
refinishing.
CAUTION: During heat cure, the effective panel temperature must not exceed 95°C.
