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

Auto

Anti-lock Br

Where appropriate a section comprises the following sub-sections:
Description and Operation
A ge

fication of the particular system or component.
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
t diagram is included to provide circuit iden
tification and details of connectors, splices, fuses, wire
gauge and colors. See Circuit Diagrams.
Diagnosis and Testing (dedicated to fault analysis and rectification)
Recommended special tools. Symptom chart; a ch

ning all relevant Diagnostic Trouble Code s (DTC), their possible causes and an
indication of the appropriate test.
Sp
