A master index of numbered operations has bee? compiled for universal application to all vehicles manufactured by
Jaguar Cars Ltd.
Each operation described in this manual is allocated
a numberfromthe master indexand cross-refers with an identical
number in the Service Repair Operation Times Manual. The number consists of six digits arranged in three pairs.
Each operation is described in the sequence necessary to complete the operation in the minimum time, as specified
in the Manual of Repair Operation Times.
SERVICE TOOLS
Where non-standard service tools (i.e. tools which are not generally available hand tools) are required to complete an
operation, the number and an illustration of that tool is given in the preliminary pages of the Section concerned.
TORQUE TIGHTENING SPEClFKATlONS
Torque tightening specifications are given in tabular form in the preliminary pages of the relevant Section.
REPAIRS AND REPLACEMENTS
When service parts are required, it is essential that only genuine Jaguar / Daimler replacements are used.
Attention is drawn to the following points concerning repairs and the fitting of replacement parts and accessories:
0 Safety features embodied in the vehicle may be impaired if other than genuine parts are fitted. In certain
territories, legislation prohibits the fitting of parts which are not produced to the vehicle manufacturer's
specification.
0 Torque wrench setting figures given in this Manual must be strictly adhered to.
0 Locking devices, where specified, must be fitted. If the efficiency of a locking device is impaired during removal it must be renewed.
0 Owners purchasing accessories while travelling abroad should ensure that the accessory and its fitted location
on the vehicle conforms to mandatory requirements existing in their country of origin.
0 The vehicle warranty may be invalidated by the fitting of other than genuine Jaguar / Daimler parts. All Jaguar
/Daimler replacements have the full backing of the factory warranty.
0 Jaguar / Daimler dealers are obliged to supply only genuine service parts.
REFERENCES
References to the left or right-hand side of the vehicle are made as if viewing from the driver's seat.
SPECIFICATION
Purchasers are advised that the specification details set out in this Manual apply to a range of vehicles and not to any
specific one. For the specification of a particular vehicle, purchasers should consult their dealer.
The Manufacturers reserve the right to vary their specifications, with or without notice, and
at such times and in such
manner as they thinkfit. Major as well as minorchanges may be involved in accordance with the Manufacturer's policy
of continuous improvement.
Whilst every effort is made to ensure the accuracy
ofthe particulars contained in this Manual, neither the Manufacturer
nor the Dealer, by whom this Manual is supplied, shall in any circumstances be held liable for any inaccuracy or the

GLOSSARY OF TERMS
Introduction
This glossary of terms is intended to cover both general and emissions-related (to SAE J 1930) terminology. It is in- tended to enable the user to ascertain the meaning of standardized terms and acronyms used throughout the Manual.
The required term may be looked-up in the left-hand column, and subsequent columns give the standard abbreviation
or acronym, definitions and previously used terms, as applicable.
As this Manual is a world
-wide publication, and must comply with certain Society of Automotive Engineers Standards, it has been necessary to adopt the terminology etc. demanded by that Standard.

0 2.1 JACKING AND LIFTING
2.1.1. Safety Precautions
The following safety precautions must be observed when
raising the vehicle to perform service operations:
0 Whenever possible use a ramp or a pit in preference
to a jack, when working beneath a vehicle.
0 Never rely on a jack to support a vehicle; use axle
stands or blocks under the vehicle jacking points to
provide rigid support.
0 When working beneath a vehicle, chock the wheels in
addition to applying the handbrake.
0 Ensure that the vehicle is standing on firm, level
ground before using the jack
0 Check that any lifting equipment used has adequate
capacity for the load being lifted and is in full working
order.
2.1.2 Jacking Points
The jack provided in the vehicle toolkit engages with jacking
points situated below the body side members, in front of the
rear wheels (Fig.
1) and behind the front wheels (Fig. 2).

Fig. 3
2.1.3 WheeLFree L i#t
Use of a wheel-free lift is recommended for maintenance operations. Support the vehicle using lifting pads at the four
jacking points (Fig. 3).

Position the jack under the lower spring support pan (Fig. I), using a wooden block placed between the jack head and the
spring support pan. Place an axle stand
in position at the ad- jacent jacking point when the wheel has been raised.
2.1.4.2 Front - Both Wheels
Position the jack centrally under the front crossmember (Fig. 2), using a wooden block placed between the jack head and
the crossmember. Place axle stands under both front jack- ing points when the vehicle has been raised.
2.1.4.3 Rear - Both Wheels
Place the jackcentrally underthe rear crossmember (Fig. 3), using a wooden block placed between the jack head and the
crossmember. Place axle stands under both rear jacking
points when the vehicle has been raised.

2.2 VEHICLE RECOVERY
8 2.2.1 General
m: Prior to vehicle recovery, always ensure the vehicle
keys are available and the vehicle security system is
'OFF'.
The safest and preferred method of vehicle recovery is by
flat bed transporter, although a rear suspended tow may
also be used.
The front and rear towing eyes are provided for use only in
an emergency to move the vehicle
if it is causing an
obstruction, on police instructions, or, when winching the
vehicle onto a recovery transporter.
m: A towing shackle cannot be fastened to the front
towing eye until the grille vane has been removed.
To do this, remove the (three) quarter
-turn fasteners
securing the grille vane (Fig. I), and place the vane
safely to one side. The towing shackle may now be
secured to the towing eye.
0 When thevehicle is being towed (see Towing Recovery), the
gear lever must be set to neutral, 'N' (see Gear-shift Inter- lock) and the ignition key turned to position 'II'to release the
steering lockand renderthe indicators, horn and brake lights
operational.
2.2.2 Gear-shift Interlock
The gear selector lever may only be moved from the park 'F" position by turning the ignition key to position '11' on the key
switch and applying pressure to the footbrake pedal.
To remove the ignition key from the key switch, the gear
selector lever must be moved to park
'P. With the key removed, the gear selector lever will be locked
in park
'P'.
2.2.3
In the event of electrical failure or when moving the vehicle
without power, the gear selector lever can be manually
unlocked from park
'P'. Below the left-hand side of the 'J' gate (Fig. Z), is the gear- shift interlock manual release catch. With a flat bladed
screwdriver, remove the plug, arrowed (Fig. 2). Insert
ignition key and press down catch whilst simultaneously
moving the gear
-shift lever from 'P' position.
Gear-shift Interlock - Manual Override
U: Gear-shift lever can only be moved approximately
25mm with the key still inserted.
Remove key and replace plug. Fig.
