2004 JAGUAR XJ main battery

Security and Locks 2 - 5
Note:
1. The key transmitter may not operate correctly in areas which are subject to
interference from other radio
equipment operating on the same
frequency. Interference may emanate
from sources such as amateur radio,
telecommunications devices, medical
equipment, and other remote controls
or alarms. Where such interference is
experienced operate the key
transmitter as close as possible to the
vehicle, or use the key in the drivers
door lock.
2. All buttons on the key transmitter will not operate if a key is in the ignition
switch, however, if the doors, hood or
luggage compartment are open, only
button ( D) will not operate.
Each integrated key will operate all the
locks on your vehicle.
Additional integrated key transmitters
can be ordered from your Jaguar Retailer.
See Additional keys on page 2 - 7. Care of key transmitters
The key transmitters must be treated with
care. Do not expose to extremes of heat,
dust, humidity or fluids. Do not leave the
transmitter exposed to direct sunlight.
The battery is the only serviceable part.
Caution: Should a key transmitter be
lost, a new one can be obtained and
programmed to the vehicle by a
Jaguar Retailer, who will ask for proof
of vehicle ownership. It is advisable
to notify a Retailer as soon as a key
transmitter is lost or stolen and have
the remaining key transmitter(s)
reprogrammed. This will then
prevent the lost or stolen key
transmitter from being used to
disarm and unlock the vehicle.
Note:
Retailers keep a log of all enquiries
for replacement keys and notify
Jaguar Cars Ltd. of any such requests.

Before Driving 3 - 13
Inertia reel mechanism check
Static test: Whilst seated, fasten the seat
belt and grip the shoulder belt at
approximately shoulder level with the
opposite hand. Pull the belt sharply
downwards, the belt should lock.
Road test: The following road test must
be carried out only under maximum safe
road conditions.
With the seat belt correctly fitted to the
driver and passenger(s), drive the vehicle
at 5 mph (8 km/h) and, ensuring that it is
safe to do so, brake sharply.
The seat belt(s) should lock automatically,
holding both driver and passenger(s)
securely in position.
It is important when braking that the
reactions of both driver and passenger(s)
are normal, that is, the body must not be
thrown forward in anticipation, thus
causing a snatching action of the belt
which would operate the locking
mechanism.
If the belt fails to lock on either test,
consult a Jaguar Retailer.
!WARNING:
1. Seat belts are designed to bear upon the bony structure of the
body. The lap section of the belt
must be worn low across the front
of the pelvis and NOT across the
abdominal area. Always ensure
that the webbing is midway
between the neck and the edge of
the shoulder.
2. Care should be taken to avoid contamination of the webbing
with polishes, oils and chemicals,
and particularly battery acid.
Cleaning may safely be carried out
using mild soap and water.
If webbing becomes frayed,
contaminated or damaged,
discard it and fit a new seat belt.
3. It is essential to renew the entire assembly after it has been worn in
a severe impact even if damage to
the assembly is not obvious. 4. Belts should not be worn with the
webbing twisted.
5. Each seat belt assembly must only be used by one occupant; it is
dangerous to put a seat belt
around a child being carried on
the occupant’s lap.
6. No modifications or additions s h o u l d b e m a d e b y t h e u s e r w h i c h
will prevent the seat belt adjusting
devices from operating.
7. Should the seat belt not retract and remain at its static length,
consult your nearest Jaguar
Retailer immediately.

Immobilising the rear windows
To immobilise the rear windows (and
operation of the front seat by a rear seat
passenger, when this feature is fitted),
press button (A) (see previous page
illustration). The LED in the button will
light up showing that the rear windows
cannot be operated by rear seat
occupants. Pressing the button again will
enable occupants to operate the rear
windows. See also Rear Seat
Adjustment on page 3 - 4.
Window Anti-trap Protection
Each electrically operated window has an
anti-trap protection feature.
If the upward movement of the window
detects an obstacle the anti-trap system
will immediately stop the window
closing, then move it downwards for a
short distance.
!WARNING:
If the battery is disconnected or
discharged the window anti-trap
feature is lost. When the battery is
reconnected or recharged the
window anti-trap system must be
reset. To reset the electrically operated
windows anti-trap system
• Fully close the window, hold the
switch in the close position for two
seconds and then release the switch.
Wait for two seconds, do not open
the window.
• Again, select the same window to close, holding the sw itch for a further
two seconds.
• Check to confirm the operation by opening the window and then use
one-touch operation to close the
window.
• Repeat for the remaining electrically operated windows.
To override the anti-trap protection
The anti-trap system will also stop the
window closing if a bl ockage or resistance
occurs e.g. in the wi ndow guide channels.
Typically this might be due to icing in
winter but could also be caused by
damage or mis-alignment of the guide
channels or seals. To override the anti-trap action:
• After the initial attempt to close the
window, operate the close switch a
second time.
• When the window has reversed from the blockage, operate the switch
(within 10 seconds) until the window
stops again (it will not reverse on the
third attempt).
• Immediately operate the close switch again. The window will now move up
a short distance with increased force
to override the blockage.
• Repeat the override action until the window has closed. Each time the
window stops, the switch must be
operated immediately to initiate
further override action.
If this procedure fails to move the
blockage, the anti-trap feature will be lost
and must be reset (see previous column)
after the blockage has been cleared.
Thermal overload
If the windows are repeatedly opened
and closed (e.g. by a child), a protection
system will deactivate window operation
for a short period to avoid overheating of
the window motors.

Parkbrake
The switch which operates the parkbrake is mounted on the
centre console to the rear of the gear selector.
To engage the parkbrake, pull the parkbrake switch upwards
and release. The switch will return to the neutral position.
The parkbrake warning/brake fluid low warning light on the
instrument cluster will illuminate.
To disengage the parkbrake, with the ignition switch in
position ‘II’ or with the engine running, apply the footbrake and
press the parkbrake switch down.
The parkbrake is automatically released when the gear selector
is moved from Park ‘P’ position.
If the vehicle is stationary and the gear selector is in ‘D’ or ‘R’
and the parkbrake is applied, then the parkbrake will
automatically release when the accelerator pedal is depressed. Inadvertent operation of the parkbrake whilst the vehicle is in
motion will cause the message ‘PARKBRAKE ON’ to be
displayed on the message centre, the warning light in the
instrument cluster will be illuminated and a warning chime will
sound.
If the parkbrake is applied whilst
the vehicle is moving, push the
switch down to release it. If the switch is in the neutral position
after parkbrake application, depressing the accelerator pedal
will release the parkbrake.
Note: If the vehicle is in motion, the parkbrake should only be
used as an emergency brake.
The parkbrake is auto matically applied when the key is removed
from the ignition switch. If you wi sh to keep the parkbrake off,
press and hold the parkbrake switch down and, at the same
time, remove the key.
Caution: Take care that the vehicle is safely parked to
prevent it from rolling if you wish to leave the parkbrake
off.
The warning light in the instrument cluster will remain on for a
short time if the parkbrake is applied when the key is turned to
position ‘0’ or if the key is removed.
If the battery has been discharged or disconnected a message
‘APPLY PARKBRAKE’ will be displa yed when the ignition is next
switched on. Depress the footbrake and pull the parkbrake
switch up to apply the parkbrake. This is required to reset the
parkbrake system which will now function correctly.
