2004 JAGUAR XJ battery reconnection

2 - 18 Security and Locks
If the system has been passively armed it
can be disarmed by either using the key
transmitter, by switching the ignition to
position ‘II’, or by unlocking the driver’s
door with the key.
Note:The security system will not
passively arm if a key is in the ignition
switch or if any protected entry is open.Battery Reconnection
If the battery has been disconnected and
is subsequently reconnected, the alarm
system will resume the same state as
before the battery was disconnected.
If the alarm was sounding when the
battery was disconnected, it will sound
again when the battery is reconnected
and will need:
• The transmitter un lock button to be
pressed
• Or a key placed in the ignition switch and turned to position ‘II’
• Or the driver’s door to be unlocked with a key
to disarm the vehicle.
Battery Back-up Sounder
(Retailer Option)
A self-contained, battery back-up
sounder can be fitted. This device will
sound the full alarm if the vehicle alarm is
activated, or if the ve hicle battery or the
sounder is disconnected when the
security system is armed.

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.

7-16 Maintenance
Battery lead disconnection
Caution:
1. Under no circumstances should a battery be discon nected whilst
the ignition circuit is live,
as permanent damage to the
instrument cluster may occur.
2. Disconnect the negative lead (earth terminal) first.
Fold the luggage compartment floor panel
forwards (see page 6 - 4).
Slacken the negative lead pinch bolt and
disconnect the negative (–) battery lead.
Slacken the positive lead pinch bolt and
disconnect the positive (+) battery lead. Battery lead connection
Note:
Upon battery reconnection the
security system will be armed. Opening
any protected entry will sound the alarm.
Make sure that a key or key transmitter is
available.
Caution: Do not overtighten the
pinch bolts.
Clean the battery posts and coat the post
bases with petroleum jelly.
Connect the positive (+) lead, tighten the
pinch bolt and clip the positive terminal
cover on the battery. Connect the
negative (–) lead and tighten the pinch
bolt.
After the battery ha s been reconnected
and the ignition swit ch is turned to
position ‘II’, the message centre display,
if fitted, will initially show an erroneous
reading i.e.––––––. Thiswill remain
until after the bulb check sequence, when
the correct recorded mileage will be
displayed. This is a normal function of the
instrument cluster.
After battery reconnection
After reconnecting the battery:
• Reset the electric parkbrake; refer to Parkbrake on page 4 - 34. • Reset the electrically operated
windows anti-trap function; refer to
Window Anti-trap Protection on
page 4 - 30.
• The trip computer will lose all recorded trip data and all trip
functions will be reset to zero.
The vehicle total odometer reading is
retained.
• If the battery is disconnected for more than 72 hours the radio preset
channels will need to be reset.
• Where fitted, the TV preset channels may need to be reset. Refer to the
Jaguar Touch-screen Handbook.
• Reset the clock to the correct time.
The engine electronic control system
adapts to certain characteristics of the
vehicle. These adaptations are lost if the
battery is disconnected.
On reconnection, therefore, some slightly
abnormal drive symptoms may occur and
the vehicle may need to be driven
10 miles (16 kilometres) or more while
the control system re-adapts.
