Warning indicator lamp illumination is controlled by a microprocessor located inside the instrument panel.
The seven right
-hand warning indicators are primary warning lamps illuminating 'RED and the seven left-hand warn-
ing indicators are secondary warning lamps illuminating 'AMBER'
The eight lower lamps are
a mixture of status and warning lamps.
With the ignition
'OFF' the LCD is not illuminated.
With ignition
'ON' and side lights 'OFF' the LCD is illuminated at maximum brightness.
With the ignition on and side lights
'OFF' the LCD is dimmed as are the gauges.
The long
life type bulbs are enclosed by orange and brown coloured bulb holders which must never be interchanged.
Replacement bulbs must always be of the same colour.
CAUTIQN: Always dwonnect the battery ground lead before commencing with any instrument rsimwal procedure.
15.2.12 General Repair Notes
0 After lens removal do not rest instrument panel face down as this causes damage to the delicate gauge needles.
Avoid scratching the gauge faces and ensure cleanliness when handling the panel.
0 To minimize the risk of damage and contamination to the instrument panel, all repairs must be carried out in a non - static and dust -free environment. Avoid touching connector pins and pcb components to minimize
risk of static damage.

15.5.8 wific Gravity Test
The specific gravity of the electrolyte determines the level of the float in the liquid. With the float in a high position
the specific gravity is high and when the specific gravity is low the float sinks to the lower position.
Using
a hydrometer the specific gravity readings are taken when the liquid level crosses the scale on float. This should
give a accurate indication of the state charge of the battery.
The volume and the specific gravity of the electrolyte varies with the change in temperature.
15.5.9 Electrolyte Temperature Correctkm
For every 10- below 15% subtract 0.007 from the hydrometer reading, and for every 10°C above 15OC add 0.007 to
the hydrometer reading.
Note: Use only distilled water for topping up electrolyte. The electrolyte must not exceed 51.66OC during charging.
If after 30 minutes charging the battery current is not equal or greater than 3A, dispose of the battery.
15.5.10 Heahh and Sakty Precautions
As batteries contain sulphuric acid and explosive mixtures of hydrogen and oxygen gases, it is strongly recommended
that protective clothing is worn.
Avoid spilling acid to prevent damage to clothing and skin bums.
If accidentalty spilled or splashed on clothing or skin, rinse with cold water. As a neutralizer, a solution of baking soda
or ammonia and water may be used.
In the event of skin or eye contact rinse the affected areas with water and should this not
be sufficient seek medical
attention.
Any trace of acid spilled or splashed on the vehicle should be rinsed with clean water.
BEFORE AND WHILST WORKING WITH THE BATTERY BE AWARE OF THE FOLLOWING SAFETY PRECAUTIONS
o particularly during charging, highly explosive hydrogen is emitted.
0 do not smoke when working near the battery.
o avoid sparks, short circuits or other sources of ignition.
o switch off current before connecting or disconnecting any electrical terminals.
o always disconnect battery ground lead first and reconnect last.
o ensure battery is charged in a well ventilated area.
o switch off the charger before disconnecting.
WARNING: WHEN PREPARING ELECTROLYTE OF A DESIRED SPECIFIC GRAVITY, ALWAYS POUR THE
CONCENTRATED ACID SLOWLY INTO THE WATER AND NOT WATER INTO THE ACID.
HEAT IS GENERATED WHEN MIXING ACID WITH WATER, HENCE ADD SMALL AMOUNTS OF ACID AND
STIR SLOWLY INTO THE WATER. ALLOW TO COOL IF NOTICEABLE HEAT DEVELOPS. EXCEPT FOR LEAD
DO NOT STORE ACID
IN EXCESSIVELY WARM LOCATIONS OR DIRECT SUN LIGHT.FUEL VAPOUR IS EXTREMELY FLAMMABLE, HENCE GREAT CARE MUST BE TAKEN WHILST WORKING ON THE FUEL
SYSTEM. LINED

The single windscreen wiper blade is controlled by a windscreen wiper/washer switch located on the right-hand side
of the steering column switchgear (see Fig.
1).
POWER WASH & SCREEN WASH/ WlPE
Windscreen Washers & Wipers, General Description
The windscreen wiper motor, part of the wiper motor
assembly operates at slow or fast speeds and drives the
lever assembly, a single arm and blade via a crank.
On
V12 engined vehicles the wiper motor assembly is
mounted to the front of the bulkhead with the motor
protruding into the plenum chamber, whilst on AJ16 engined vehicles the wiper motor assembly is mounted into
the same position, but with the motor protruding into the
engine compartment.
For wipe and wash operation
a mixture of water and special
'Jaguar Windscreen Fluid' is drawn from the PVC reservoir
assembly by
two electrically controlled pumps and is then
distributed via flexible feeder hoses interconnected using
'TEE' pieces to the screen wash jets and to heated power
wash jets (where fitted). The ends of power wash hoses are
fitted with 'quick
fit' fluid connectors.
The
two pumps, one for screen wash and one for headlamp
power wash are externally fitted to the reservoir located at
the front right
-hand side of the engine compartment.
Contained within the reservoirs pull-up neckis a serviceable
filter.
The screen wash jets with independently adjustable
eyeballs are mounted on the plenum chamber finisher and
the temperature of the fluid passing through the jets is
controlled from an ambient temperature sensor fitted near
the inlet of the right
-hand side air duct. Fig.
1
The
fluid temperature for each of the headlamp wipe wash operation is controlled by self regulating, heated power
wash jets mounted on to either side of the bumper.
Each powerwash jet is protected by
a cover supplied with an integral cover-to-bumperseal. The cover snap fixes into
the bumper.
15.6.2
This switch only operates with the ignition switch in position '11' and has the following functions:
windscreen Wiper and Washer Switch
Position 0 The wind screen wiper is switched 'OFF' and parked.
Position 1: Normal speed wiper operation is obtained by pushing the switch lever up one position.
Position 2: High speed wiper operation is obtained by pushing the switch lever fully up.
Position D: To obtain intermittent wiper operation the switch lever is pushed down and released.
The delay period will vary with vehicle speed. To cancel the function repeat the procedure.
15.6.2.1 Single Wipe Operation
To obtain a single sweep of the wiper blade, the lever is pulled towards the steering wheel and released.
W The intermittenmick wipe operations are both at slow speed and they are controlled by a Central Control
Module (CCM), which also controls the headlamp power wash operation.
Issue 1 August 1994 X300 VSM

15.6.2.2 Programmed Wash / Wipe Operation
The end of the switch lever must be pressed inwards for the windscreen wash and wipe operation. Wash / wipe con- tinues for as long as the lever is pressed.
When released, the windscreen wiper stops immediately and the wiper blades sweep for
a further three wipes.
On pressing the end of the switch lever inward and then releasing
it, the windscreen washers operate for approximately
two seconds before stopping, whilst the wiper blade continues for a further three wipes.
N&: If the end of the switch lever is pressed while the washer fluid warning light is illuminated, the windscreen
washers, but not the wiper blade continues to operate.
0
15.6.2.3 Headlamp Power Wash Operation (where fitfed)
The headlamp power wash operates only when the programmed washer/ wipe function is selected and the side lights
are 'ON'
The headlamp power wash does not operate if the windscreen washer reservoir fluid lever is low. This is indicated
by the washer fluid level warning light illuminating.
&&: The headlamp power wash only operates on the 1st and every 6th succeeding cycle of the programme wash /wipe switch, after the ignition switch has been turned to position '11'.
