2004 JAGUAR XJ Change

3 - 22 Before Driving
Driving Position
!WARNING:
Driver and front seat passenger
should always move their seats as far
rearwards as is practical.
Ideally, drivers should sit with at least
10 inches (25.4 cm) between the centre
of their breastbone and the cover of the
steering wheel air bag.
Since the risk zone at the time of
deployment is the first 2 to 3 inches
(5.5 cm – 7.5 cm) from the air bag cover,
sitting back 10 inches (25.4 cm) provides
a clear margin of safety. Very few drivers
are unable to achieve and maintain that
safety gap. The vast majority of drivers who do not
now sit that far back can change their
position and achieve that distance.
• If adjustable pedals are fitted, move
them towards the seat.
• Move your seat back as far as you can while still comfortably reaching the
pedals.
• Recline the back of your seat one or two notches from the upright
position. If reclining the back of your
seat makes it hard to see the road,
raise the seat.
• Tilt the steering wheel/column downwards so as to point the air bag
at your chest instead of your head and
neck. Adjust the steering wheel/
column fore/aft so that it extends
towards the driver as little as possible,
ensuring that the air bag has plenty of
room to deploy.
• Sit in the centre of the seat with the head as close to the head restraint as
possible. Note:
Seat, steering wheel and pedal
adjustment controls are described
elsewhere in this section.

4-4 On the Road
Engine Temperature (E)
Drive at moderate road and engine
speeds until normal operating
temperature is reached. This is indicated
when the pointer is between the
blue (cold) segment and the red (hot)
segment.
The engine operating temperature will
vary with changes in weather and engine
load. The engine temperature may rise in
some circumstances, such as:
• Idling for long periods in slow moving traffic.
• Driving up a long hill in hot weather.
• Driving slowly or stopping after driving at high speed.
• Towing a trailer or caravan.!WARNING:
1. The radiator cooling fans may continue to run after the ignition
has been switched off but will
automatically switch off when the
engine has cooled sufficiently.
2. It is unsafe to run the engine in an overheated condition.
3. Do not remove the coolant reservoir filler cap while the
engine is hot. If it is essential, then
protect your hands against
escaping steam. SLOWLY turn the
cap anti-clockwise to allow the
steam pressure to escape
completely before removing the
cap. Should the pointer move into the red
segment (
H) of the coolant gauge, stop
the vehicle as soon as it is safely possible,
turn off the engine and open the hood to
allow the engine to cool.

4-12 On the Road
Message Centre
Driver information, messages and data
are displayed on the message centre
display panel situated within the
instrument cluster.
For the message centre to operate the
ignition must be switched ON
(position ‘II’).
The primary function of the message
centre is to inform the driver of the
following:
• Warning messages.
• Temporary alert messages.
• Information messages.The message centre displays:
• The total distance covered by the
vehicle.
• Trip computer information.
• Warning messages if system faults are detected.
• Status messages to indicate changes in
state of certain vehicle functions.
Messages
!WARNING:
If a red warning light is displayed,
investigate immediately and,
if necessary, stop the vehicle as soon
as possible but only when it is safe to
do so.
Most messages, when displayed, have an
associated warning light, red or amber,
above the display which will come on to
indicate the message priority.
If more than one message is active, each
is displayed in turn for two seconds in
order of priority.
Messages take priority over the odometer
reading or trip computer data and,
if active, will be displayed when the
ignition is switched ON. Message centre illumination
The message centre is lit at all times when
the ignition is ON, and message
brightness is controlled by the dimmer
switch.
All information displayed will be brightly
lit if the exterior light switch is OFF.
Note:
Warning lights are always brightly
lit and are not affected by the dimmer
switch.
Language Selection
The displayed language can be changed
to another language, if required.
Press the ML/km button on the trip
computer switchpack and whilst pressing,
turn on the ignition to position ‘II’.
Now press the ML/km button, each press
will display a different language.
When the desired language is shown,
press the A/B button. After three seconds
the new language will be displayed for
every message.
Note: If you wish to exit the language
changing procedure and keep the original
language, do not press the A/B button but
wait 10 seconds or turn the ignition off.

CRUISE NOT AVAILABLE Amber Adaptive cruise malfunction.
FORWARD ALERT ON (or OFF) None Forward alert feature has been switched ON or OFF. A warning will not be given
for objects detected in the vehicle path of travel if forward alert is switched OFF.
FORWARD ALERT None Forward alert feature has been switched ON or the setting changed. A warning will
be given for objects detected in the vehicle path of travel. A longer gap indicates
that the system will warn when detected objects are further away than the
previous setting.

4-44 On the Road
Note:
1. After selecting forward or reverse drive ranges from Neutral or Park,
wait briefly for th e transmission to
engage before accelerating.
2. When in Neutral or Park the engine can only be a ccelerated to
4500 rev/min.
R = Reverse – Do not select if the vehicle
is moving forward.
The reversing lights come ON
automatically when reverse gear is
selected and the ignition switch is in
position ‘II’.
D = Drive – All six gears are changed
automatically as required by the throttle
position and road speed.
2, 3, 4, 5 = If selected, the transmission
operates automatically in second, third,
fourth or fifth gear but will not engage
gears higher than the one selected. Drive to fifth
When driving in gear position ‘D’ with
sixth gear engaged, the gear selector can
be shifted sideways across the gate to ‘
5’.
Provided that the vehicle’s speed is not
too great, the transmission will shift
down to fifth. Sixth gear will be inhibited
until the gear selector is moved back to
‘D’.
Hill climbing and engine braking
When driving on roads with long
downhill gradients, selecting ‘3’ or ‘2’
(depending on road/traffic conditions)
will give engine braking.
When the gear selector is moved
from ‘D’, ‘5’, ‘4’ or ‘3’ down to ‘2’,
downshift to second ge ar will only take
place at appropriate road speeds.
Reverse inhibit
Reverse is inhibited when the vehicle is
moving forward at speeds above 5 mph
(8 km/h).
Note: Reverse inhibit will not function in
limp-home mode. Kickdown
Kickdown is operated when the pedal is
pressed fully down, beyond the normal
operating range and against a spring
pressure, to provide maximum engine
performance. Kickdown is used in
circumstances where rapid acceleration is
required, such as when overtaking.
Kickdown causes the transmission to
change down to the lowest gear possible
to achieve maximum acceleration.
The gear engaged depends on the road
speed at the time of kickdown.
As well as shifting
down, the gearshift
points are extended to give greater
performance. This mode is in effect for as
long as the pedal is pressed fully down.

On the Road 4 - 49
Cruise (Speed) Control
The cruise (speed) control system can be
used by the driver to maintain a selected
vehicle speed above 17.5 mph (28 km/h)
without the driver having to use the
accelerator.
Switches on the steering wheel allow the
driver manual control of the system.
Brake operation also influences the cruise
control system. (
A ) – RESUME to resume the set speed
retained in memory.
( B ) – SET to set the speed or increase/
decrease the set speed when the speed
has been set.
( C ) – CANCEL cancels cruise control but
retains the set speed in memory.
Setting the Vehicle Speed
!WARNING:
Only use cruise control when
conditions are favourable,
for example, straight, dry, open roads
with light traffic.
When you are travelling at the speed you
require, which must be above 17.5 mph
(28 km/h), press the SET button.
Cruise control will engage and maintain
the set speed and you can remove your
foot from the accelerator pedal.
Note: Cruise control will automatically
disengage when the brake pedal is pressed
or when the vehicle speed falls below
16 mph (26 km/h).
Changing the Set Speed
There are three ways to change the set
speed:
1. Accelerate or decelerate to the desired speed then press the SET (+) button.
2. Increase or decrease the speed by pressing and holding either SET (+)
or (–) until the desired speed is
obtained, then release the switch.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing either the SET (+) or (–) until
the desired speed is obtained.
Resuming the Set Speed
If the vehicle is accelerated above the set
speed, then the set speed will be resumed
when the accelerator pedal is released.
If CANCEL is pressed, or the brake pedal
is pressed, the cruise control will
disengage but the set speed memory will
be retained. Press RESUME and the
vehicle will return to the set speed.
Note: Cruise control will not resume at
speeds below 17.5 mph (28 km/h).
RESUME will not operate if the ignition
has been turned off.

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.

4-54 On the Road
Changing the set speed
There are three ways to change the set
speed:
1. Accelerate or brake to the required speed and press the ‘SET +’ button.
2. Increase or decrease the speed by pressing and holding either the
‘SET +’ or ‘–’ button until the required
set speed is shown on the message
centre. The vehicle speed will
gradually change to the selected
speed.
3. Increase or decrease the speed in steps of 1 mph (2 km/h) by briefly
pressing the ‘SET +’ or ‘–’ button.
ACC operates between approximately
20 mph and 110 mph (34 km/h and
180 km/h) dependent on the country
specification.
Set speeds outside this range will not be
captured.
The ACC may apply the brakes to slow
down the vehicle to the new set speed.
The new set speed will be displayed on
the message centre for four seconds after
it has been changed. Changing the gap
The gap from the vehicle ahead can be
decreased or increased by pressing the
gap setting rocker switch on the steering
wheel. Four gaps are available and the
selected gap setting will be displayed on
the message centre when the rocker
switch is pressed. After the ignition is
switched ON the default gap will be
automatically selected ready for ACC
operation.
Note:
It is the driver’s responsibility to
select a gap appropriate to the driving
conditions, and in accordance with
national driving regulations.
ACC automatic switch off
Adaptive cruise control will disengage,
but not clear the memory when:
• The CANCEL button is pressed.
• The brake pedal is pressed.
• The vehicle speed falls below 18 mph (30 km/h).
• Neutral, Park or Reverse gear positions are selected.
• The parkbrake is applied.
• DSC is activated. Adaptive cruise control will disengage,
and clear the memory when:
• The ignition switch is set to
position ‘0’.
• Maximum vehicle speed is reached.
• A fault occurs in the ACC system.
Resuming the set speed/follow mode
By pressing the RESUME button after ACC
has been cancelled, for example, after
braking, the ACC will become active
again provided that the set speed
memory has not been erased. The set
speed will be displayed for four seconds
and the original set speed will be
resumed, unless a vehicle ahead causes
the follow mode to become active.
Caution: ‘RESUME’ should only be
used if the driver is aware of the set
speed and intends to return to it.
