2004 JAGUAR XJ sound system

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.

Occupant Protection
Seat Belts
The use of front and rear seat belts is
mandatory in most countries. Using seat
belts saves lives. They should be worn by
all occupants whenever the vehicle is in
use, for maximum protection.
Lap/shoulder inertia reel seat belts are
provided for both front occupants and
three rear seat positions.
The inertia operating mechanism of the
seat belts allows the wearers to move
their upper bodies to reach various
controls. The seat belts lock automatically
with accelerated body movement or in
the event of emergency braking.
The seat belt assemblies incorporate
additional safety devices. All have belt
pretensioners and the front belts also
have force limiters. These devices provide
increased protection in the event of a
severe frontal impact.
The pretensioners operate with the air
bags as part of the Advanced Restraints
Technology System (see page 3 - 14). All passenger seat belt mechanisms
incorporate an automatic locking device
to allow child seats to be secured safely.
Forchild safety seepage3-23.
Comfort belts are fitted to both individual
electrically operated rear seats. They are
also fitted to the outer seats only on the
electrically operated rear bench seat.
These belts incorporate a twin tension
facility. When the belt is buckled around
the occupant, a reduced tension is
applied to provide a more comfortable
fitting. When the belt is unfastened,
a higher tension is applied to allow it to
retract correctly.
Beltminder
The Beltminder feature is a supplemental
warning to the seat belt warning function
(see page 4 - 6). This feature provides
additional reminders to the driver that
the driver’s and/or front passenger’s seat
belt is unbuckled by intermittently
sounding a chime and illuminating the
seat belt warning lamp in the instrument
cluster.
Note:
Not all countries have the warning
chime. Front belt height adjustment
To adjust the front seat belt heights, press
the locking button and slide the
anchorage so that the seat belt webbing
passes over the shoulder without pulling
against the neck. Release the button and
check that the anchorage point is locked.
Always check the anchorage point after
the seat has been adjusted to ensure that
the belt is correctly positioned.

Direction Indicators (GREEN)
The appropriate
indicator tell-tale
light will flash when
the column switch is moved up or down
to signal a right or left-hand turn.
If a direction indicato r fails, the tell-tale
will flash at twice normal rate when that
indicator is selected. A message will be
shown that a bulb has failed. Fit a new
bulb immediately.
Note:
1. If a bulb has failed, the audible ticking will sound at twice the normal rate.
2. If a trailer or caravan is fitted and a direction indicator bulb fails then the
tell-tale will flash at twice the normal
rate and a message will be displayed
that a rear indicator lamp has failed.
Hazard Warning Lights
When the hazard warning is selected,
both direction indicator tell-tale lights
flash simultaneously.
Low Fuel Level
An amber warning light is displayed in
the gauge when the fuel in the tank is at a
low level. The tank should be refilled at
the earliest opportunity.

4-10 On the Road
Audible Warnings
Various sounds are produced for warning and notification purposes as follows:
Hazard or Condition Remedy/chime or tone
Air bag system failure. A tone sequence is repeated five times. Report the fault to a Jaguar Retailer as
soon as possible.
External lights remain ON when the driver’s door
is opened. A chime will sound for 10 seconds as a warning that the lights are on when
the ignition is off and the drivers door is opened. Switch lights off.
Note:
The chime will not sound if the switch is in Autolamp position.
Key in ignition switch. A chime will sound if the key has been left in the ignition and the driver’s
door is opened after the ignition has been switched off or turned to
position ‘I’.
Hazard warning indicators ON. A ticking will sound until the hazard indicators are switched OFF.
Vehicle armed. This warns that the alarm will sound shortly unless the system is disarmed by
either pressing the unlock button on the key transmitter or by placing the key
in the ignition switch.
Left or right direction indicators ON. If the switch has not turned itself OFF, switch the turn indicator OFF when
the manoeuvre is completed. A ticking will sound until the indicators are
switched OFF.
Memory 1, 2 or 3 configuration saved. A short tone as the memory selection is saved.

4-34 On the Road
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.

On the Road 4 - 35
Park Distance Control
Caution: It remains the driver’s
responsibility to detect obstacles and
estimate the car’s distance from
them. Some overhanging objects,
barriers, thin obstructions or painted
surfaces which could possibly cause
damage to the vehicle may not be
detected by the system. Always be
vigilant when reversing.
Park distance control is always
automatically switched on when the
ignition is turned on.
Caution:
1. If, for example, you are driving into a confined space such as a
home garage, the outer sensors
will detect the side walls and after
3 seconds will switch the tone off.
However, as movement
continues, the inner sensors will
eventually detect the rear wall
and will start the tone again.
2. The sensors are not active when the gear selector is in neutral,
therefore, take care if moving the
vehicle as the tone will not be
heard.
3. Do not clean the sensors with abrasive or sharp objects. Note:
1. For reliable operation, the sensors in
the front (if fitted) and rear bumpers
should be kept free from frost, ice and
grime.
2. When using a high pressure spray the sensors should only be sprayed briefly
and at least 8 inches (20 cm) distance
from the sensors.
3. The front parking aid may sound spurious tones if it detects a frequency
tone using the same band as the
sensors.
Rear Park Distance Control
When reverse gear is selected and
ignition is on, rear park distance control
automatically provides an audible
proximity warning (to the nearest
detected obstacle) when reversing the
vehicle if obstacles are detected within
the operating range, shown in the
illustration above (between
approximately 24 inches [60 cm] ( A) and
63 inches [160 cm] ( B).

On the Road 4 - 53
When a vehicle ahead enters the same
lane or a slower vehicle is ahead in the
same lane, the vehicle speed will be
adjusted automatically until the gap to
the vehicle ahead corresponds to the
preset gap. The vehicle is now in ‘follow
mode’.The warning light in the
instrument cluster will be
illuminated,
and the message centre
will display the gap set.
The vehicle will then maintain the
constant time gap to the vehicle ahead
until:
• The vehicle ahead accelerates to a speed above the set speed.
• The vehicle ahead moves out of lane or out of view.
• The vehicle ahead slows so that ‘low speed automatic switch off’ occurs.
• A new gap distance is set.
If necessary, the vehicle brakes will be
automatically applied to slow the vehicle
to maintain the gap to the vehicle in
front. The maximum braking which is applied
by the ACC system is limited and can be
overridden by the driver applying the
brakes, if required.
Note:
Driver braking will cancel adaptive
cruise control.
If the ACC system predicts that its
maximum braking level will not be
sufficient, then an audible warning will
sound while the ACC continues to brake.
This is accompanied by a red warning
light and ‘DRIVER INTERVENE’ will be
displayed on the message centre.
The driver should take IMMEDIATE
action.
When in follow mode the vehicle will
automatically return to the set speed
when the road ahead is clear, for instance
when:
• The vehicle in front accelerates or changes lane.
• The driver changes lane to either side or enters an exit lane.
The driver should intervene if
appropriate.
Low speed automatic switch off
If the speed of the vehicle decreases
below 18 mph (30 km/h), the ACC system
will be automatically switched OFF and
the instrument warning lamp will go out. If the brakes were
being applied by the
ACC system, they will be slowly released.
This will be accompanied by an audible
warning, a red warning light and ‘DRIVER
INTERVENE’ will be displayed on the
message centre. The driver must take
control.
Overriding the set speed/follow mode
!WARNING:
Whenever the driver is overriding the
ACC by depressing the accelerator
pedal, the ACC will not automatically
apply the brakes to maintain
separation from any vehicle ahead.
The set speed and gap can be overridden
by pressing the accelerator pedal when
cruising at constant speed or in follow
mode. If the vehicle is in follow mode,
the instrument warning lamp will go out
when the ACC is overridden by the driver
using the accelera tor and ‘CRUISE
OVERRIDE’ will be displayed on the
message centre. When the accelerator is
released the ACC function will operate
again and vehicle speed will decrease to
the set speed, or a lower speed if follow
mode is active.
GAP

On the Road 4 - 55
Forward alert
Limited detection and warning of objects
ahead is provided during ACC operation
by the ACC ‘DRIVER INTERVENE’
warning.
The forward alert feature additionally
provides warnings whilst ACC is not
engaged, if an object is detected close
ahead then a warning tone and message
will be issued. The brakes will not be
applied.
This additional feature may be switched
on or off using the forward alert switch in
the lower outboard knee bolster
switchpack. When the indicator lamp in
the switch is on, forward alert is active.The sensitivity of the warning may be
changed:
• Pressing the gap decrease button
when ACC is disengaged displays and
then decreases the sensitivity of the
alert.
• Pressing the gap increase button displays and then increases the
sensitivity of the alert.
Both of these are accompanied by the
FORWARD ALERT message on
the message centre.
ACC failure
If a fault occurs during operation of the
system in cruise or follow modes,
the ACC system will switch OFF and
cannot be used until the fault is cleared.
A red warning light and the message
‘DRIVER INTERVENE’ appear briefly, and
are then replaced by an amber warning
light and the message ‘CRUISE NOT
AVAILABLE’.
If failure of the ACC or any related system
occurs at any other time an amber
warning light will be displayed
accompanied by th e message ‘CRUISE
NOT AVAILABLE’. It will not be possible
to activate the ACC system in any mode. Accumulations of dirt, snow or ice on the
on the sensor or cover may inhibit ACC
operation. Fitting of a vehicle front
protector or metallis
ed badges may also
affect ACC operation.
If this occurs in ACC cruise/follow mode,
the red warning light is displayed,
the audible alarm sounds and the
message ‘DRIVER INTERVENE’ appears
briefly. These warnings are then replaced
by the amber warning light and the
message ‘ACC SENSOR BLOCKED’ is
displayed. The system is no longer active.
Clearing the obstruction allows the
system to return to normal operation.
If the obstruction is present when ACC is
inactive, e.g. on initial starting or with the
ACC system switched off, the amber
warning light will be displayed with the
message ‘ACC SENSOR BLOCKED’.
Tyres other than those recommended
may have different sizes. This can affect
the correct operation of the ACC.
