2004 JAGUAR XJ warning

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.

On the Road 4 - 45
Limp-home mode
In the unlikely event of an electrical or
mechanical failure, transmission
operation will be impaired. The vehicle
gear selector ranges P, R, N, D can still be
used to enable the vehicle to be driven to
a safe area. In this event consult a Jaguar
Retailer immediately.
!WARNING:
The driver should be aware that the
vehicle’s performance will be
reduced and must take this into
account when driving.
Sport Mode
The switch marked ‘S ’ on the ‘J’-gate
surround enables the driver to select
either normal or sport (S) modes.
When sport mode is selected the
automatic transmission will operate
normally, but the ge arshift points are
extended to make full use of the engine’s
power reserves.
To select ‘Sport’, press the switch. A red
light within the switch is illuminated to
indicate that sport mode has been
selected.
To cancel ‘Sport’, press the switch again. Note:
Both sides of the ‘J’-gate can be
used irrespective of the transmission
mode, e.g. with ‘S’ selected the
transmission can be operated in full
automatic or by manual selection.
In addition to norm al and sport modes,
the transmission control computer will
select shift patterns to suit specific
conditions.
Cruise Control – When cruise control is
operating at set speed the transmission
selects a shift pattern to suit cruise
control operation.
DSC – When DSC is switched ON and the
system is activated, the transmission
selects a shift pattern to suit traction
control conditions.
Gradients – When the vehicle is being
driven on roads with uphill gradients,
the transmission adapts the shift pattern
to make better use of engine power and
aid engine cooling.
Note: Under the conditions described,
the relevant transmission mode will
override the normal or sport modes
selected by the driver.
When such conditions no longer exist,
the transmission will revert to the shift
pattern previously selected by the driver,
that is, normal or sport.

4-46 On the Road
Dynamic Stability
Control (DSC)
Unless it has been switched off, dynamic
stability control is operational whenever
the engine is running. If the system is
operating, the warning light in the
instrument cluster will flash.
The DSC system controls the anti-lock
braking system (ABS), traction control
and yaw control of the vehicle.Yaw control determines the vehicle’s
direction relative to
the driver’s inputs
(sideslip and under/ov ersteer). It applies
braking pressure to individual wheels if
excessive variation is detected.
This ensures that the vehicle follows the
driver’s intended direction of travel.
Traction control will intervene to reduce
wheel spin, by automatically reducing the
power output from the engine and
applying braking to individual wheels.
This improves acceleration, particularly
on surfaces with uneven friction,
for example, one wheel on ice the other
on tarmac.
ABS helps to prevent the road wheels
from locking and skidding during
emergency braking.
When the system is operating,
the warning light in the instrument
cluster will flash.
The dynamic stability control system can
be switched OFF by pressing the switch
on the centre console switchpack.
The warning light in the instrument
cluster will remain on and a message will
be shown to indicate that the system has
been switched OFF. If the switch is
pressed again the system will switch ON. Note:
If cruise control is engaged it will
automatically disengage if stability control
activates.
A system malfunction is indicated by the
message:
DSC NOT AVAILABLE
Warning light: Amber .
and the instrument cluster DSC warning
light will be lit.
It is safe to drive the vehicle but the
system may not activate under wheel spin
or slide conditions. Report the fault to a
Jaguar Retailer as soon as possible.
!WARNING:
1. The fact that the vehicle is fitted with Dynamic Stability Control
must never allow th e driver to be
tempted into taking risks which
could affect his/her safety or that
of other road users. In all cases it
remains the driver’s responsibility
to drive safely according to the
prevailing conditions.
2. It is recommended that when using snow chains, DSC should be
switched OFF.

On the Road 4 - 47
Anti-lock Braking
System (ABS)
This system helps to prevent the road
wheels from locking and skidding during
emergency braking, assisting the driver to
maintain full steering and directional
stability.
The factor controlling ultimate stopping
distance and cornering ability is tyre/road
adhesion.
!WARNING:
1. The fact that a vehicle is fitted with ABS must never allow the
driver to be tempted into taking
risks which could affect his/her
safety or that of other road users.
2. The addition of ABS cannot overcome the consequences of
trying to stop in too short a
distance, cornering at too high a
speed, or the risk of aquaplaning. 3. The driver should always take
road conditions into account.
A slippery road surface always
requires more braking distance
for a given speed, even with ABS.
A possible increase in stopping
distance compared to locked
wheels may occur during ABS
operation on slushy snow, gravel,
sand, or some heavily corrugated
or ridged warning sections of road
surfaces.
ABS optimises tyre/road adhesion under
maximum braking conditions though it
cannot provide increased cornering
ability. There is no need for special
braking techniques, such as ‘pumping’
the brakes, to achieve optimum braking
distances and control on poor or slippery
road surfaces. Tyres must be in good
condition to achieve maximum adhesion. During normal brakin
g the ABS will not
be activated. Howe ver, if the braking
force applied begins to exceed tyre/road
adhesion the ABS will automatically
activate, preventing the road wheels from
locking.
In these circumstances a pulsating effect
will be felt from the brake pedal
indicating that the sy stem is functioning.
The pulsating effect is due to small
fluctuations in pressure supplied to the
brakes by the system to maintain full
tyre/road adhesion.
Under severe braking on some road
surfaces tyre noise may be apparent even
though the wheels will at no time become
locked.

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 - 51
Adaptive Cruise Control (ACC)
(Where fitted)
The adaptive cruise control system is designed to aid the driver
to maintain a gap from the vehicle ahead or a set road speed if
there is no slower vehicle ahead. The system is intended to
provide enhanced operation of th e vehicle when following other
vehicles which are in the same lane and travelling in the same
direction.
!WARNING:
Adaptive cruise control is not a collision warning or
avoidance system. Additionally , adaptive cruise control
will not detect:
1. Stationary or slow moving vehicles below 6 mph (10 km/h).
2. Pedestrians or objects in the roadway.
3. Oncoming vehicles in the same lane. The adaptive cruise control system is based on the use of a radar
sensor which projects a beam directly forward of the vehicle so
as to detect objects ahead. Th e radar sensor is mounted behind
a cover on the left-hand side of the lower cooling aperture,
to provide a clear ‘view’ forward for the radar beam.
• Only use adaptive cruise control when conditions are favourable, that is, straight, dry, open roads with light traffic.
• Do not use in poor visibility, specifically fog, heavy rain,
spray or snow.
• Do not use on icy or slippery roads.

4-52 On the Road
• It is the drivers responsibility to stay alert, drive safely and be in control of
the vehicle at all times.
• Keep the front of the vehicle free from dirt, metal badges or objects,
including vehicle front protectors,
which may prevent the sensor from
operating.
• Do not use ACC when entering or leaving a motorway.
The system is operated by switches
mounted on the steering wheel.
The driver can also intervene at any time
by use of the brake or accelerator pedals.
The steering wheel switches operate as
follows:
(A ) – RESUME: Resume set speed.
( B )– SET+ or SET–: Setthe speed(+) or
increase (+) or decrease (–) the set speed.
( C ) – CANCEL: Cancels without erasing
memorised speed.
( D ) – Gap increase or decrease. Setting a speed
Accelerate as normal
until the required
speed is reached.
Press the SET + butto n briefly and the
vehicle speed will then be stored in the
memory and the system engaged. The set
speed will be displayed on the message
centre.
Entering the follow mode
!WARNING:
When in follow mode the vehicle will
not decelerate automatically to a
stop, nor will the vehicle always
decelerate quickly enough to avoid a
collision without driver intervention.
Once a set speed has been selected,
the driver can release the accelerator and
the set road speed will be maintained.
