patc
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. 
Specia
 l Tools 
Any special too
ls and equipment required
 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:
