2004 JAGUAR XJ Battery

Roadside Emergency 6 - 5
Caution:
1. If using a jump start vehicle, under no circumstances should the
vehicles come into contact with
each other. This could establish an
earth connection, which may
cause sparks and damage.
2. Do not run the engine of the jump start vehicle when boost starting a
Jaguar vehicle. If the jump start
vehicle’s engine is running and
the jump leads ar e disconnected,
damage to the Jaguar vehicle’s
electrical system will result.
3. The booster battery voltage must not exceed 12 volts.
The procedure must be followed exactly,
being careful not to cause sparks:
1. Unclip the battery positive (+) terminal cover.
2. Attach one end of the red jump lead to the positive (+) terminal of the
booster battery and the other end to
the positive (+) terminal of the
discharged battery. Make sure that a
good connection is made.
Caution: Do not connect the negative
jump lead directly to the negative (–)
terminal of the discharged vehicle. 3. Attach one end of the black jump lead
to the negative (–) terminal of the
booster battery and the other end to
the earth stud on the left-hand side of
the spare wheel well.
4. Start the engine.
5. When started, allow the engine to idle for five minutes before disconnecting
the cables.
6. Disconnect the black jump lead from the earth point and the booster battery
negative (–) terminal. 7. Disconnect the red jump lead from the
positive (+) terminals of both
batteries.
8. Refit the cover to the positive (+) terminal.
9. Close the trunk floor panel.
After starting the engine, it may be
necessary to reset th e electric parkbrake
as described on page 4 - 34. See also After
battery reconnection on page 7 - 16.

Roadside Emergency 6 - 21
Fuses and Fuse Boxes
Do not fit a new fuse if the wiring is
damaged; contact a Jaguar Retailer.
After renewing a fuse have the circuit
checked by a Jaguar Retailer.
Two types of fuses are fitted in the fuse
boxes, ATO type and Midi type.
Spare fuses and a special tool for
removing and replacing fuses are located
on a removable panel clipped to the rear
of the trunk ( A).
Use only the spare fuses supplied. If a
spare fuse is used, renew it with a Jaguar
approved fuse of the same amperage
rating.
Checking and Renewing a
Blown Fuse
Make sure the new fuse is the correct
rating (amperage).
Fuses are colour coded according to the
amperage and the rating is also marked
on each fuse.
Caution: When a fuse box lid is
removed, take care to protect the box
from moisture, and refit the lid at the
earliest opportunity. ATO-fuse replacement
Push the tool on to the suspect ATO fuse
and withdraw the fuse. If the wire in the
fuse is broken, the fuse has blown.
Fit a new fuse using the tool.
Midi fuse replacement
(not shown)
Unscrew the two nuts and remove the
fuse. Note that the fuse is supplied
directly from the battery +ve; take care
not to short a spanner or other metal tool
to the chassis when removing the nuts.!WARNING:
1. Do not fit a fuse of a different amperage from that removed.
The electrical circuits may
become overloaded with the
subsequent possibility of a fire.
2. No attempt should be made to repair a fuse that has blown as this
may cause a fire hazard or serious
damage elsewhere in the
electrical circuit.

6 - 22 Roadside Emergency
Fuse Box Locations
There are three separate fuse boxes fitted
to the vehicle, each one containing fuses
protecting a different group of circuits.
Engine compartment fuse box
The fuse box is located in the engine
compartment on the right-hand side
adjacent to the windscreen wash
reservoir.
Remove the fuse box lid by pressing the
spring catch and lifting.
When refitting, press the fuse box lid in
the area of the retaining lugs until the lid
engages. Cabin fuse box
The cabin fuse box is located behind the
right-hand side trim panel in the footwell.
To access the fuse box, pull out the
bottom of the trim panel (arrowed), slide
the panel down slightly and remove.
Trunk fuse box
A fuse box is located in the trunk,
situated behind the battery.
Open the trunk floor panel to gain access
to the fuse box.
Remove the fuse box lid by pulling the
retaining clips and pulling the lid
upwards.
Reposition the lid and press down until
the retaining clips engage.
Replace the floor panel.

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.
