Safety Notice
Appropri
ate service me
thods and proper repair procedures are essential for the safe, reliable operation of all motor vehicles,
as well as the safety of the person do ing the work. This manual provides genera l directions for accomplishing service and
repair work with tested, effect ive, techniques. Following them will help assure reliability.
There are numerous variations in procedures, techniques, tools, and parts for servicing vehicles, as well as in the skill of the
person doing the work. This manual cannot possibly anticipate all such variations and provide advice or cautions as to each.
Accordingly, anyone who depart s from the instructions provided in the manua l must first establish that neither personal
safety nor vehicle integrity is compromised from choices of methods, tools or parts.
Notes, Ca
utions and Warnings
Throughout
this manual, important inform
ation is highlighted by the use of notes, cautions and warnings. NOTES give
additional information on a topic or proc edure, CAUTIONS are given to prevent da mage to the vehicle, and WARNINGS are
given to prevent personal injury.
Worksh
op Manual Organization
This
manual incorporates descript
ive, diagnostic, and repair information to help trained Jaguar technicians complete service
and rectification procedures. The informat ion can be accessed by choosing the appropriate five digit section number. For
example, Section 412-03 covers air conditioning , which is part of the Climate Control System.
The manual is organized into groups covering generic aspects of the vehicle systems; the first digit of the section
number represents a group se lected from the following:
1. General Information.
2. Chassis.
3. Powertrain.
4. Electrical.
5. Body and Paint.
Each of the groups comprises sections re lating to specific areas of the vehicle.
The second and third digits of the section number indicate the vehicle system.
The last two digits of the se ction number define the system covered, more specifically.
Each section comprises one or more of the following sub-sections:

Torque Specifications
Torque sp
ecifications are shown in maintenance procedure illustra
tions and also in the torque specifications chart located at
the front of the relevant section.
Disconnecting/Connecting the Battery
Ow ing t
o the electronic components used on the vehicle, it is important that the battery is disconnected when specified in a
maintenance procedure.
When the battery is connected, the specified procedure must be followed, to ensure the correct operation of all vehicle
systems; refer to Section 414-01.
Use of Control Modules
Control modu les may
only be used on the ve
hicle to which they were originally fitted. Do not attempt to use or test a control
module on any other vehicle.
Function
al Test
On
completion of a maintenance procedure, a thorough test should be carried out, to ensu
re that the relevant vehicle
systems are working correctly.
Protecting the Vehicle
Al ways
fit covers to protect
the fenders before commencing work in the engi ne compartment. Cover the seats and carpets,
wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic fluid,
antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water imme diately. Use polythene sheets
in the trunk to protect carpets. Always use the recommended service tool, or a satisfactory equivalent, where specified.
Protect temporarily exposed screw thread s by replacing nuts or fitting caps.
Preparation
Before disassembly, clean the surrounding ar ea
as thoroughly as possible. When co
mponents have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oilways, exposed
by component removal, with tapered hardw ood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a se parate container for each component and its associated pa rts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the
materials within the component. Clean the bench and obtain ma rking materials, labels, containers and locking wire before
dismantling a component.
Dismantling
O b
serve scrupulous cleanliness when dismantling components,
particularly when parts of the brake, fuel or hydraulic
systems are being worked on. A particle of dirt or a fragment of cloth could caus e a dangerous malfunction if trapped in
these systems. Clean all tapped holes, crev ices, oilways and fluid passages with compressed air. Do not permit compressed
air to enter an open wound. Always use ey e protection when using compressed air.
Ensure that any O-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure that
they are replaced as dismantled. Whenever possible use markin g materials which avoid the possibilities of causing distortion
or the initiation of cracks, which could occur if a center pu nch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed fo r reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not disc ard a part which is due for renewal until it ha s been compared with the new part, to ensure
that the correct part has been obtained.
