2004 JAGUAR XJ Ignition switch

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.

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).

4-36 On the Road
Front and Rear Park Distance
Control
When both front and rear park distance
control are fitted, a switch is located in
the overhead console.
Pressing the switch turns front and rear
park distance control on or off together.
The switch integral warning lamp will
come on when the system is turned off or
if a fault is detected in the system.
A switch is not provided when only rear
park distance control is fitted.
Note: The front park distance control will
also operate when reverse gear is
selected. Front park distance control provides an
audible proximity warning when driving
forwards if objects are detected within
the operating range shown in the
illustration above (between
approximately 24 inches [60 cm] (
A) and
31 inches [80 cm] (C ) to the front of the
vehicle). The front sensors only operate
within a fixed speed range in forward
gears and are not effective when moving
forwards above 9mph (15km/h) or when
slowing down until below 4½ mph
(7 km/h).
If an obstacle is detected at the front or
rear of the vehicle, a beep tone will be
heard from the front or rear speaker
respectively, which increases in rate as
the vehicle approaches the obstacle. The front or rear park distance control
beep will become co
ntinuous when the
obstacle is detected at or within
12 inches (30 cm) from the rear or
approximate 10 inches (25 cm) from the
front of the vehicle.
If the system has a fault when engaging
reverse gear or turning on the ignition,
then a single, three second tone will be
heard (only once per ignition cycle) and,
if fitted, the switch lamp will come on.
The system is automatically disabled
when a fault is detected.

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.

On the Road 4 - 43
To Stop the Engine and Lock
the Steering
Turn the key from position ‘II’ to the
‘lock’ position ‘0’. This turns off the
ignition and stops the engine.
The steering will be locked when the key
is removed from the switch.
Leaving the key in position ‘I’ or ‘II’ will
discharge the battery.
Automatic Transmission
The ‘J’-gate gear selector lever is designed
to accommodate two different driving
techniques as follows:
• Automatic selection – the right-hand side of the selector gate.
• Manual selection – the left-hand side of the selector gate to individually
select 5th, 4th, 3rd, or 2nd gear.
Gearshift Interlock
A brake pedal/gearshift interlock system
is incorporated in the automatic gear
selector mechanism.
To move the gear selector from Park:
1. Turn the ignition key to position ‘II’ or start the engine.
2. Press the brake pedal.
3. Move the lever from Park.
Gear Selector Positions
!WARNING:
The parkbrake or brake pedal must
be applied before selecting forward
or reverse drive from a stationary
position.
P = Park – Use when parking. In this
position the transmission is locked.
Do not select if the vehicle is moving.
N = Neutral – Disconnects the driveline
from the engine. Use the parkbrake when
stopping temporarily.

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.

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.
