2004 JAGUAR XJ service

Maintenance 7 - 7
Recommended Engine Oil
When the oil level is at the lower dipstick mark, add 1 US quart
(1.0 litre) of oil.Oil specification
– API SJ/EC and ILSAC GF–3
When topping up between oil chan ges, make sure that you use
oil that has the correct quality le vel (API service) and viscosity
grade. Your vehicle’s warranty ma y be invalidated if damage is
caused by use of improper engine oil.
For maximum fuel economy, 5W–30 oil is recommended.
SAE viscosity rating
For climates ranging from –22°F (–30°C) and +122°F (+50°C),
the following oil viscosities may be used:
0W–30
5W–30 (preferred)
0W–40
5W–40
Note: It is recommended that the oil level is topped up using oil
of the same viscosity. If you are unsure which oil viscosity is used
in your car, your Jaguar Retailer will be able to advise.
If you are operating this vehicle in climates outside the above
temperature range, contact your Jaguar Retailer for advice.

Maintenance 7 - 13
Battery
A low maintenance battery specifically
designed for use with this vehicle is fitted
below the luggage compartment floor.
!WARNING:
California Proposition 65:
Battery posts, terminals and related
accessories, contain lead and lead
compounds. Wash hands after
handling.
!WARNING:
1. The cell plugs and vent pipe must
be in place at all times when the
battery is in the vehicle. Failure to
fit, or incorrect fitting of these
items is potentially hazardous.
2. To avoid injury do not use an open flame or cause an electric spark
when checking the battery.
Hydrogen gas generated by the
battery is flammable and may
explode. 3. Do not connect any 12 volt
equipment (for example a 12 volt
lead lamp) directly to the battery
terminals. Use the accessory
sockets to temporarily connect
Jaguar approved accessories.
4. Do not let battery acid electrolyte come into contact with skin or
eyes. If you get any in your eyes or
on your skin, immediately rinse
with cold water and consult a
doctor.
Caution:
1. Switch off the ignition before disconnecting battery terminals.
Always disconnect the earth
terminal first and reconnect last.
2. Do not let battery acid come into contact with painted surfaces or
fabric.
The exterior of the battery should be
occasionally wiped clean to remove any
dirt or grease.
If a new battery is to be fitted, it must be
the same type as the original.
The use of unapproved batteries is not
recommended and coul d invalidate the
vehicle warranty. Note:
The service life of the battery is
dependent on its condition of charge.
It must always be sufficiently charged for
the battery to last an optimum length of
time.
We recommend that the battery charge is
checked frequently if the vehicle is used
mostly for short distance trips, or if it is
not used for long periods of time.
Battery/ignition isolator switches
Non-approved battery isolator switches,
which disconnect the power supply to all
electrical circuits, are not recommended.
Generator
To prevent damage to the generator,
do not run the engine while the battery
or any of the charging circuit cables are
disconnected.
The generator has polarity-sensitive
components that may be irreparably
damaged if subjected to incorrect
polarity. Ensure that the battery earth
lead is always connected to the battery
negative terminal.

United States Department of
Transportation/Uniform Tyre Quality
Grades
The following information relates to the
tyre grading system developed by the
National Highway Traffic Safety
Administration which will grade tyres by
tread wear, traction and temperature
performance.
Tread wear
The tread wear grade is a comparative
rating based on the wear rate of the tyre
when tested under controlled conditions
on a specified government test course.
For example, a tyre graded 150 would
wear one and a half (1.5) times as well on
the government course as a tyre
graded 100.
The relative performance of tyres
depends upon the actual conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate. Traction – A, B, C
The traction grades, from the highest to
the lowest are ‘
A’, ‘ B’ and ‘ C’, and they
represent the tyre’s ability to stop on wet
pavements as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tyre
marked ‘ C’ may have poor traction
performance.
!WARNING:
The traction grade assigned to this
tyre is based on braking (straight
ahead) traction tests and does not
include cornering (turning) traction. Temperature – A, B, C
The temperature grades ‘
A’ (the highest),
‘ B ’ and ‘C ’ representing the tyre’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tyre to degenerate and
reduce tyre life, and excessive
temperature can lead to sudden tyre
failure.
The grade ‘ C’ corresponds to a level of
performance which all passenger car
tyres must meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades ‘ B’ and ‘ A’ represent higher levels
of performance on the laboratory test
wheel than the minimum required by
law.
!WARNING:
The temperature grade for this tyre is
established for a tyre that is properly
inflated and not over loaded.
Excessive speed, under-inflation or
excessive loading, either separately
or in combination, can cause heat
build-up and possible tyre failure.

7-22 Maintenance
Vehicle Care
Valet kit
A valet kit containing a selection of Car
Care products is available from the Jaguar
accessory range.
Interior Care
Brush and clean the interior regularly.
Use a vacuum cleaner where possible to
remove all dust from the interior and
trim.
Carpets
Marks or stains can be removed by gentle
scrubbing with a weak solution of soap
and warm water.
For more stubborn stains a commercially
available carpet cleaner should be used.
See your Jaguar Retailer for advice.
Headlining
Remove dust in the headlining with a
vacuum cleaner. To remove stains,
dab gently without pressing, using a
fluff-free white cloth, moistened with
Jaguar Upholstery Cleaner.
Do not use methylated spirit or solvents
as this may cause damage or
discoloration to the headlining.Leather upholstery
Dust and dirt can penetrate the pores and
creases of leather, causing surface wear
and brittleness. To prevent ingrained dirt,
inspect the seat upholstery regularly and
clean every one to two months as follows:
• Wipe the seat surfaces with a clean,
damp, non-coloured cloth, changing
frequently to a clean area of cloth.
Avoid over-wetting.
• If this is not sufficient, use a cloth which has been dampened with warm
soapy water and then wrung out;
avoid over-wetting. Use only mild
non-caustic soap.
• Use Jaguar Leather Cleaner for heavily soiled areas.
• Dry off and rub with a clean soft cloth, changing su rfaces regularly.
When staining (e.g. from clothing) or
spillages occur, clean the affected area
immediately as described above. Note:
Do not use solvents such as petrol
(gasoline), white spirit or alcohol. Do not
use detergents, furniture polish or
household cleaners. Although such
treatments may give, initially,
an impressive appearance, their use will
lead to rapid damage or deterioration of
the leather, and will not be covered by the
Manufacturer’s Warranty. Unless spillages
such as tea, coffee or ink are washed away
immediately, permanent staining may
have to be accepted.
If a valeting service is used, ensure that
the specialist firm concerned is aware of
these instructions, and they follow them
precisely.
