Brakes
The pressure at the inlet valves corresponds to the opening pressure of the relief valve (item 15) incorporated in the
isolation valve. Excess brake fluid is drained to the suction side of the pump via the relief valve and returns either to
the TMC secondary circuit and on to the
fluid reservoir, or is directly drawn on by the pump.
As soon as the spinning wheel has been braked down into the normal range of wheel spin, the NO valves (items
16 or 17) close to prevent any further increase in brake pressure. Depending upon the acceleration of the wheel, the NC
valve (item
20 or 21) may open to decrease thesecondary circuit brake pressure. NCvalves (item 17 or 18) may remain
closed in orderto achieve a brake pressure holding phase. If the pressure in the secondarycircuit needs to be increased
again, the NC valve closes again (if open) and the NO valve opens, diverting the necessary volume flow. This control
action, keeps the wheel in the range of optimum slip until the spinning tendency ceases.
The NO isolation valve
(14) remains closed throughout the traction control cycle.
An actuation of the brake, sensed by the control module, causes the traction control mode to be terminated and the
isolation valve (item
14) to be opened. The TMC pressure simultaneously closes the hydraulic inlet valve (item 13) so that the pump can no longer draw fluid from it. The ABS / TC CM now operates in normal ABS mode.
m: When traction control is initiated, speed control is deactivated (if in operation) and requires re-setting after
the traction control mode has terminated. Gear shift is inhibited on automatic transmission vehicles; no down- shifts are allowed and upshifts occur at 4800 RPM.

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

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

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.

13.7.6 Repair of Damaged Carpet
The most common cause of accidental damage to carpets is cigarette burns (especially to polypropylene carpet).
These can be repaired easily on new carpets by cutting out the face material in the affected area and replacing with new face material with a latex locking coat of approximately 100g/m2 dry then incorporating a P.S.A.B. (pressure sensi- tive adhesive backing) which would be applied to roll carpet in the form of a laminate film at Firth Furnishings subsidi- ary Textile Bonding, Higham Ferrers, Northampton, UK.
The
film has a peelable release paper, which means that the new material would simply be cut to size, the release paper
removed and then the new carpet pressed into position.
The problem
in replacing areas in old or soiled carpets is that the replacement of damaged areas with new carpet would
create a visual difference, ie un-worn pile, clean appearance, which would then cause the repaired area to stand out
from the rest of the carpet. The only answer would be to abrade the rest of the new carpet to the same degree as the
old carpet.

14.1 WORKING PRACTICES
14.1.1 General
o Be aware of, and comply with all health and safety requirements, whether they be legislative or common sense.
This applies to conditions set both for the operator and workshop.
o Before commencing any repair or service procedure, disconnect the vehicle battery ground connection and
protect the vehicle where appropriate, from dirt or damage.
0 Work in a well ventilated, clean and tidy area (Fig. 1).
0 Keep all components and tools clean.
0 Recovery / Recycle and Recharge equipment must comply with, or exceed the standard detailed in the
preliminary pages.
Fig.
1
14.1.2 Handling Refrigerant
0 Wear eye protection at all times. Use gloves, keep skin that may come into contact with HFC 134A covered.
Should refrigerant come into contact with your eyes or skin; wash the affected area with cool water and seek
medical advice, do not attempt to treat yourself.
o Avoid breathing refrigerant vapour, it may cause ir- ritation to your respiratory system.
0 Never use high pressure compressed air to flush out
a system. Under certain circumstances HFC 134A +
compressed air + a source of combustion (welding
and brazing operations in the vicinity), may result in
an explosion and the release
of potentiallytoxiccom-
pounds.
0 HFC 134A and CFC 12 must never come into contact
with each other (Fig. 21, they will form an inseparable
mixture which can only be disposed of by inciner
-
ation.
0 Do not vent refrigerant directly to atmosphere, al- ways use Jaguar approved recovery equipment. Re-
member, HFC 134A is costly but recycleable.

Climate Control Systems
0 Because HFC 134A is fully recycleable it may be 'cleaned' by the recovery equipment and re-used following
removal from a system.
0 Leak tests should only be carried out with an electronic analyzer which is dedicated to HFC 134A. Never use a CFC 12 analyzer or naked flame type.
0 Do not attempt to 'guess' the amount of refrigerant in a system, always recover and recharge with the correct
charge weight. In this context do not depress the charge or discharge port valves to check for the presence of
refrigerant.
14.1.3 Handling Lubricating Oil
0 Avoid breathing lubricant mist, it may cause irritation to your respiratory system.
0 Always decant fresh oil from a sealed container and do not leave oil exposed to the atmosphere for any reason
other than to fill or empty a system. PAG oil is very hygroscopic (absorbs water) and will rapidly become con-
taminated by atmospheric moisture.
PAG oil is
NOTcompatible with previously used mineral based oils and must NEVER be mixed (Fig. 1). Do not
re
-use oil when it has been separated from refrigerant, following a recovery cycle. Dispose of used oil safely.
14.1.4 System Maintenance
0 When depressurizing a system do not vent
refrigerant directlyto atmosphere, always use Jaguar
approved recovery equipment.
0 Always decant compressor oil from a sealed con- tainer and do not leave oil exposed to the atmosphere
for any reason other than to fill or empty
a system.
PAG oil is very hygroscopic and will rapidly become
contaminated by atmospheric moisture.
0 Plug pipes and units immediately after disconnection
and only unplug immediately priorto connection. Do
not leave the system open to atmosphere.
0 It is not necessary to renew the receiver drier when- ever the system has been 'opened' as previously ad-
vised - see note this page. However,if a unit or part
of the system is left open for more than five minutes,
it may be advisable to renew the receiver drier. This
guidance is based on
U.K average humidity levels;
therefore, locations with lower humidity will be less
critical to moisturecontamination of the unit.
It must
be stressed that there is not
a 'safe' period for workto
be carried out in: ALWAYS plug pipes and units im-
mediately after disconnection and only remove plugs
immediately prior to connection.
J82-387
Fin. 1
U: The receiver / drier MUST be renewed if the compressor has failed or if it is suspected that debris may be in
the system.
0 If replacement parts are supplied without transit plugs and seals DO NOT use the parts. Return them to your
supplier.
0 Diagnostic equipment for pressure, mass and volume should be calibrated regularly and certified by a third
party organization.
0 Use extreme care when handling and securing aluminium fittings, always use a backing spanner and take
special care when handling the evaporator.
0 Use only the correct or recommended tools for the job and apply the manufacturer's torque specifications.

15.1.6 Fire Hazard Infonnath
Thermal decomposition or combustion may produce dense smoke and other dangerous fumes which in fire situations
form
a highly toxic explosive.
In the event of fire the surrounding area must be evacuated and
all personnel kept well upwind of the area.
Full fire fighting protective gear and
a self contained breathing apparatus operating in the positive pressure mode must
be worn for combating fire. Material near fires must be cooled with water spray to prevent ignition.
Fires should be allowed to burn themselves
out if not threatening to life or property. If fire is threatening to life or prop- erty use copious quantities of water to extinguish.
15.1.7 Ventilath
Local exhaust ventilation designed by a professional engineer should be provided if vapours, fumes, or dusts are gen- erated whilst working with airbag module.
The latest issue of the manual for recommended practices on 'Industrial Ventilation' is available from the
ACGIH Com- mittee on Industrial Ventilation, PO Box 16153, Lansing, MI 48910, USA.
The need for local exhaust ventilation should be evaluated by a professional industrial hygienist.
15.1.8 Respiratory Precauth
To prevent the inhalation of dangerous fumes and dusts, an approved mask should be worn.
15.1.9 Eye Protection
Chemical protective goggles are recommended where there is a possibility of eye contact with the propellant.
Safety glasses with side shields are recommended for
all other operations.
15.1. I0 Protective Clothing
Approved protective gloves, overalls and shoes / boots should be worn.
15.1.1 1 Handling and Storage Precautions
Do not store airbag module near live electrical equipment or circuitry. Store in a dry environment at ambient tempera-
tures.
Good housekeeping and engineering practices should be employed to prevent the generation and accumulation of
dusts. Store in compliance with
all local state and federal regulations.
15.1.12 Driver And Passenger Airbag Modules Assembly / Removal / Service Instructions
Before starting work, ensure ignition switch is in 'IocK position, key is removed and negative terminal cable
is disconnected from the battery.
As the airbag is equipped with a back up power source and due to the risk of airbag being inadvertently
deployed, wait one minute or longer before starting work.
0 Disconnecting the battery cancels the memory for clock, radio, seats, mirrors, steering column and any other
components using battery power. Reset memory after work is completed.
0 Never use airbags from other vehicles, always use new parts.
0 After work is completed, reconnect battery and perform warning light check see diagnostic manual.
0 Never use electrical probes to check voltage or electrical resistance.
0 Disconnect the airbag before carrying out any work on, or in the vicinity of module, or when using electric weld- ing equipment.
0 Always ensure that battery negative has been disconnected for one minute or longer before commencing any
removal procedure.
