hed fastener of the same specification fitted. All mating th
reads must be thoroughly cleaned prior to fitting of the new
fastener.
Jaguar Specification JFS 02.01.04 patched fasteners incorporat e a plastic/polyester on the thread. Acting as a wedge
between the mating threads, this compound imposes a prevaili ng torque during tightening. Whilst this type of patched
fastener can be re-used, the imposed torq ue diminishes. It is therefore recommended that following third removal, this type
of patched fastener is discarded and a new fast ener of the same specification is fitted.
Special fasteners bearing the following pa rt numbers are of the micro-encapsulated adhesive type and following removal,
must be discarded and replaced by ne w items of the same specification:

Vehicle Specifications

Purchasers are advised th
at th
e specification details set out in this manual apply to a range of vehicles and not to any
specific one. For the specificatio n of a particular vehicle, purchasers should consult their dealer.
The Manufacturer reserves the right to vary the specifications, with or without notice, and at such times and in such manner
as the Manufacturer thinks fit. Major as well as minor changes may be involved , in accordance with the Manufacturer's
policy of continuous improvement.
Whilst every effort is made to ensure the accuracy of the pa rticulars contained in this manual, neither the Manufacturer nor
the Dealer, by whom the manual is supplied, shall in any circumstances be held liable for any inaccuracy or the
consequences thereof.
Serv
ice Repair Operation Numbering
A
master index of numbered operations has been compiled for
universal application to all vehicles manufactured by Jaguar
Cars Ltd.
Each operation is allocated a number from the master index and cross-refers with an identical number in the Repair
Operation Times schedule. The number consists of six digits arranged in three pairs.
Each maintenance procedure in this manual is described in the sequence necessary to complete the operation in the
minimum time, as specified in the Repair Operation Times schedule for this range of vehicles.
Re
ferences to Left- and Right-Hand
R
eferences to the left- or
right-hand side of the vehicle are made as if viewing from the driver's seat.
Ref
erences to Engine Banks
Wi
th the engine installed in the vehicle, the right-hand cylinder
bank is designated Bank A, and the left-hand cylinder bank
is designated Bank B.

to perform a maintenance procedure, are shown at the beginning of each
maintenance procedure.

irri
tation and dermatitis. In addition, used engine oil contains potentially harmful contaminants which may cause skin
cancer. Washing facilities and adequate means of skin protection should be provided.
Observe these recommendations:
Wear pro t
ective clothing and impe
rvious gloves when necessary.
Do not put oily
rags in pockets. Avoid contaminat
ing clothes, particularly underwear, with oil.
Overal
ls must be cleaned re
gularly; discard oil impregna ted clothing and footwear wh ich cannot be washed or
cleaned.
Fi rst
Aid treatment should be obtained
immediately for open cuts or wounds.
Use barrier
creams, applying before each work period, to en
able easier removal of dirty oil and grease from the skin.
Wa
sh with soap and water to ensure th
at all oil is removed (skin cleaner and a nail brush will help). The use of
preparations containing lanolin will help to replace the natural skin oils which have been removed.
Do
not use petrol, kerosene, gas oil, th
inners or solvents for washing skin.
If
skin disorders develop, obtain medical advice immediately.
Wh
ere prac
ticable, degrease components prior to handling.
W
h
ere there is a risk of fluids coming into contact with th
e eyes, suitable eye protection should be worn - goggles or
face shield. An eye wash facility should be provided.
Ensure that a
dequate ventilation is provided when volatile degreasing agents are being used.
E
n
vironmental Protection
In so
m
e countries it is illegal to pour used oil onto the ground
, down sewers or drains, or into water courses. The burning of
used engine oil in small space heaters or boilers is not reco mmended unless emission control equipment is fitted. Dispose of
used oil through authorized waste disposal contractors, to licensed waste disposal sites or to the waste oil reclamation
trade. If in doubt, contact the Local Authority for advice on disposal facilities.
On-Board Diagnostics (OBD)
Ve
hicles use programmed electronic control systems to prov
ide engine management and emission regulation, automatic
transmission operation and anti -lock braking control. These control systems ha ve an integral On-Board Diagnostics (OBD)
facility for use in conjunction with either Jaguar diagnostic equipment or a scan t ool which is capable of retrieving DTCs,
PIDs and performing active commands.
The OBD information in this manual provid es diagnostic and rectification procedures for emission related electrical and
mechanical systems. The informat ion is intended to facilitate fault diagnosis and the subsequent rectification of vehicles
without recourse to the portab le diagnostic unit (PDU).
OBD related information can be fo und in the following sections:
General Information

Engine M

Anti-lock Br

A ge

A b

accompanied by a component
illustration.
Addi ti
onal information, where appropriat
e, is provided in the form of component calibrations, characteristics and
cross sectional views.
A localized circui

gauge and colors. See Circuit Diagrams.
Diagnosis and Testing (dedicated to fault analysis and rectification)
Recommended special tools. Symptom chart; a ch
