2004 JAGUAR XJ brake light

4-24 On the Road
At dawn, as light increases, the sidelights
and headlights switch OFF automatically.
Do not cover the sensor and keep the
windscreen clean. Obstructing the light in
this area of the sensor may lead to
unwanted operation of the sidelights and
headlights.
Note:If the windscreen wipers are
switched on in auto, slow or fast modes
for more than 20 seconds then the
exterior lights will be switched on,
if selected to autolamps mode. The lights
will switch off 2 minutes after the wipers
are switched off or will go off straight
away if autolamps is deselected or the
ignition is turned off.
Exit delay
When parking the car at night, if the
headlights were switched on then they
will remain on for a short period after the
key has been removed from the ignition
switch. This is to give a clearly lit area for
occupants leaving the vehicle.
If the light switch rotary collar is in the
AUTO position there will be no exit delay
and the headlights will turn off when the
light switch is turned off. Three settings on the rotary collar set the
time that the lights will remain on after
the key is removed from the ignition
switch;
•10seconds.
•30seconds.
•2minutes.
Note:
The key must not be in the ignition
switch for this feature to operate.
The message centre shows the delay
setting or when this feature is turned off.
Headlight convenience
When approaching the vehicle,
the sidelights and headlights can be
switched on by pressing the headlight
button on the re mote transmitter.
The lights will come on for 25 seconds or
can be switched off by pressing the
remote transmitte r headlight button
again. Daylight running lights
In certain countries it is a legal
requirement for the lights to be on during
the hours of daylight.
With the rotary co
llar in the OFF
position, dipped headlights, sidelights,
tail lights, number plate lights and side
marker lights will switch on automatically
with the following conditions:
• The ignition is turned to position ‘II’.
• The vehicle gear se lector out of park.
• The parkbrake is not applied (released).

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.

Starting/Stopping the
Vehicle
When the vehicle is stationary the
automatic gear selector may be left in ‘D’,
‘ 2 ’, ‘ 3’, ‘ 4’ or ‘ 5’, unless the vehicle is to
be parked. When stopping for traffic
lights, junctions etc., either select ‘ P’ or
apply the parkbrake and select ‘ N’.
Before Starting
Before starting the engine, new owners/
drivers should familiarize themselves with
the layout and operation of the controls
and instruments.
!WARNING:
Before attempting to start the engine,
check parkbrake is ON and gear
selector lever is in position ‘P’ or ‘N’.
To Start the Engine
The engine cannot be started until the
gear selector is in ‘ N’ or ‘ P’.
Insert the key into the ignition switch and
turn clockwise to position ‘II’ to switch
on the ignition.
When the key is turned to position ‘III’
the starter motor will turn the engine
until:
• The key is released and automatically returns to position ‘II’.
• The ignition switch is turned to ‘0’ or ‘I’.
• The gear selector is moved out of ‘P’ or ‘N’.
• The engine starts.
If the engine fails to start, the key must be
turned to position ‘0’ before attempting
to restart.
Do not use the starter continuously for
longer than six seconds. Continued use of
the starter will disc harge the battery and
may damage the starter mechanism.
Wait until the engine stops turning before
re-using the starter.
When the engine starts, release the key. The red charge light and the oil pressure
light in the instrument cluster should go
out when the engine is running.
If the engine fails to start
If an ignition key is placed in the ignition
switch and turned to position ‘II’ and the
alarm security light is flashing, it is
possible that the engine will not start.
In any event, please contact a Jaguar
Retailer to investigate the cause of the
light flashing.
It is possible that the fuel system inertia
switch may have tripped, see page 6 - 3
for the resetting procedure.
If the engine persistent
ly fails to start and
flooding is suspected, depress the
accelerator pedal fully, hold it in this
position and turn the key to position ‘III’
for six seconds. Release the key, remove
your foot from the accelerator pedal and
then attempt to restart the engine.
Note: The engine cannot start whilst the
pedal is fully depressed, it must be
released to enable the engine to start.
If the engine still fail s to start, switch the
ignition OFF and contact a Jaguar
Retailer.

4-48 On the Road
ABS Monitoring
The ABS control module monitors the
ABS electrical system from ignition switch
ON to ignition switch OFF.
Any malfunction will be indicated by the
anti-lock warning light coming on.
Should a fault develo p in the ABS system,
the brake system will still operate
conventionally and with the same
standard of performance as vehicles not
equipped with ABS.
Caution: Consult a Jaguar Retailer
immediately if the warning light
comes on while driving, a system
failure is indicated.
Advice on ABS Braking
Techniques
For optimum ABS performance the
instructions on braking techniques during
ABS operation should be followed:
1. Do not release brake pressure when the pulsating effect is felt. Maintain a
constant pressure until the manoeuvre
is completed. 2. To familiarise yourself with the feel of
the brake pedal duri ng ABS braking,
practise an emergency stop
procedure, always making sure it is
safe to do so. With the seat belts fitted
to all occupants, drive the vehicle at
20 mph (32 km/h) and brake sharply.
3. ABS enables the driver to steer around obstacles during emergency braking.
However, the consequ ences of turning
sharply at high speed cannot be
overcome by the ABS.
4. Do not attempt to ‘pump’ the brakes to avoid skidding as this can interfere
with the ABS operation. The ABS will
not allow the wheels to skid under
normal road conditions.
5. The ABS will tend to keep the vehicle straight during braking. Because
braking distances may increase under
certain road conditio ns, it is necessary
to plan and make turning manoeuvres
as early as possible.
Emergency Brake Assist (EBA)
The EBA system measures the rate at
which the brake pressure increases.
If the system detect s an emergency
braking situation, EBA automatically
initiates the full br aking effect. This can
reduce stopping distances in critical
situations, which can help an
inexperienced driver to stop in the same
distance as an experienced driver.
!WARNING:
The EBA system is an additional safety
system: it is not intended to relieve
the driver of his responsibility for
exercising due care and attention
when driving.

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.
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.

4-56 On the Road
Notes on using adaptive cruise
control
1. Adaptive cruise control operates when the gear selector lever is in
position ‘2’, ‘3’ ‘4’ ‘5’ or ‘D’.
2. When engaged, the accelerator pedal rests in the raised position.
Fully release the pedal to allow
normal ACC operation.
3. When braking is applied by the ACC
the brake pedal will move down and
up as braking is applied or removed.
The vehicle brake lights will be
switched on while braking is applied.
!WARNING:
The driver must not rest a foot under
the brake pedal, as it may become
trapped. Driving with ACC active
The system acts by regulating the speed
of the vehicle using engine control and
the brakes. Gear changes may occur in
response to decelerati
on or acceleration
whilst in ACC.
ACC is not a collision avoidance system,
however, during some situations the
system may provide the driver with an
indication that intervention is required.
An audible alarm will sound,
accompanied by a re d warning light and
the message ‘DRIVER INTERVENE’ if the
ACC detects:
• That using maximum ACC braking only is not sufficient.
• That the vehicle speed has decreased below the minimum for ACC
operation.
• A failure has occurred whilst the system is active.
