2004 JAGUAR XJ ESP

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.
SETSPEED 50 MPH

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

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.

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.

Touring
Foreign travel
Before planning foreign travel, check with
a motoring organisation to ensure that
your vehicle will comply with legal
requirements of the countries you intend
to visit.
International motoring organisations are
helpful for all aspects of long distance
touring advice.
In some countries it is a legal requirement
to carry spare vehicle bulbs.
First aid kit
A first aid kit is compulsory equipment in
certain countries. Your Jaguar Retailer
can supply a first aid kit.Petroleum spirit in containers
Some countries forbid the carrying of
petrol in containers, as do most ferry and
hovercraft operators.
Cellular radio telephones
Ask your motoring organisation about the
use of cellular radio telephones before
travelling abroad, as some countries
exercise controls on the importation and
use of such equipment.
Roof-rack
Only the Jaguar approved roof-rack
should be used.
The maximum load, including the weight
of the rack, must not exceed the load
rating indicated on th
e roof-rack bars and
must be deducted from the vehicle
maximum luggage load.
Loads on the roof-rack may affect vehicle
handling, especially in crosswinds or
when cornering. Jaguar warning triangle
A warning triangle to give traffic
advanced notice of a disabled vehicle is
compulsory in many countries.
A triangle, designed to international
standards is fitted as standard equipment
in certain countries. The warning triangle
with its stand legs folded flat, is mounted
on the inside of the luggage compartment
lid.
In an emergency, remove the triangle and
unfold its stand legs. Place the triangle in
the road in accordance with local traffic
regulations to give oncoming traffic
warning of an im
mobilised vehicle.
Hazard warning lights must be used with
the warning triangle.

Fuel filler flap manual release
If the fuel filler flap fails to release it can
be manually unlocked as follows:
1. In the luggage compartment, remove
the carpet from the right-hand side,
behind the rear light. To do this, turn
the carpet securing screws a ¼ turn
and then firmly pull the top corner of
the carpet down.
2. Locate the fuel flap release mechanism and pull the knob rearwards. This will
release the flap to gain access to the
filler cap and enable the vehicle to be
refuelled.
3. Report the fault to a Jaguar Retailer. Unleaded fuel
All vehicles are fitted with a catalytic
system and can only use unleaded fuel.
Unleaded fuel must be used for the
emission control system to operate
properly. Its use will also reduce spark
plug fouling, exhaust system corrosion
and engine oil deterioration.
The preferred fuel should have an octane
rating of at least 95 RON (Research
Octane Number).
‘Super Green’ Plus 98 RON unleaded fuel
(where available) may be used as an
alternative to the standard 95 RON
unleaded fuel. Some countries have only 91 RON fuel
available. The vehicles in these countries
are specially calibrated to use this fuel.
Using unleaded fuel with an octane rating
lower than recomm
ended can cause
persistent, heavy ‘spark knock’ (a metallic
rapping noise). If severe, this can lead to
engine damage.
If a heavy ‘spark knock’ is detected even
when using fuel of the recommended
octane rating, or if you hear steady ‘spark
knock’ while holding a steady speed on
level roads consult a Jaguar Retailer to
have the problem corrected. Failure to do
so is misuse of the vehicle, for which
Jaguar Cars Limited, is not responsible.
However, occasional light ‘spark knock’
for a short time while accelerating or
driving up hill, may occur.
Emission control components
Owing to the legislative requirements or
options available in some countries,
a Jaguar Retailer should be consulted
where any doubt exists as to the precise
emission control system specification of
this vehicle.

On the Road 4 - 67
Fuels containing alcohol
Caution: Take care not to spill fuel
during refuelling. Fuel containing
alcohol can cause paint damage,
which may not be covered under the
warranty.
Some fuel suppliers sell fuel containing
alcohol without advertising its presence.
Where uncertainty exists check with the
service station operator.
Note: Some difficulty in starting may be
encountered when using alcohol blended
fuel.
Ethanol
Fuels containing up to 10 per cent
ethanol (grain alcohol) may be used.
Ensure the fuel has octane ratings no
lower than those recommended for
unleaded fuel. Most drivers will not
notice any operating difference with fuel
containing ethanol. If a difference is
detected, the use of conventional
unleaded fuel should be resumed. Methanol
Some fuels contain methanol (methyl or
wood alcohol). If you use fuels containing
methanol the fuels must also contain
co-solvents and corrosion inhibitors for
methanol. Also, do not use fuels that
contain more than three per cent
methanol even if they
contain co-solvents
and corrosion inhibitors. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels is not
the responsibility of Jaguar Cars Limited,
and may not be covered under the
warranty.
Methyl Tertiary Butyl Ether (MTBE)
Unleaded fuel containing an oxygenate
known as MTBE can be used provided the
ratio of MTBE to conventional fuel does
not exceed 15 per cent.
MTBE is an ether based compound,
derived from petroleum, which has been
specified by several refiners as the
substance to enhance the octane rating of
fuel.

Climate Control 5 - 3
5 Climate Control
Introduction
The cabin is supplied with filtered air
from a fully automatic electronic climate
control system with manual overrides.
Two systems are available:
• A two zone system which allows the front occupants to set individual
temperatures for the left and right
sides of the interior.
• A four zone system which allows front and rear occupants to set individual
temperatures, i.e. two front zones and
two rear zones.
Occupant controls
The main climate control panel is located
in the centre console above the radio and
audio controls. There are two types of
control panel for either two or four zone
systems:
• A dedicated control panel with LCD (liquid crystal display) screen
(see page 5 - 6).
• A multi-function touch control and display unit shared with navigation
and other systems. Where this control
unit is fitted, refer to the Jaguar
Touch-screen Handbook for the
detailed operating instructions. Where the four zone climate control
system is fitted, an additional control/
display panel for rear passenger use is
located at the rear of the centre console,
between the front seats.
Voice control
The climate control system may also be
operated by spoken commands if the
optional voice activation system is fitted.
For full information on the use of this
system refer to the JaguarVoice
Handbook.
Recommended Operation
Automatic climate control
Automatic climate control provides
efficient regulation of the vehicle
environment without constant
adjustments from the occupant.
Sensors inside the vehicle monitor
temperature, humidity and direct
sunlight. In response, the electronic
control system automatically adjusts the
heat input, blower speed, air intake and
airflow distribution so as to maintain the
selected temperature(s) and reduce
misting.
Automatic operation provides optimum
comfort under most driving conditions. It is recommended that automatic
control (AUTO) is selected as the
normal operating mode.
Use of air conditioning
Air conditioning is an integral part of the
climate control system, providing cooled
and dehumidified
air for occupant
comfort; the dry airflow is also effective
in preventing misting of the windows.
While the air conditioner can be
manually switched off, it is recommended
that it is used in all climatic conditions
throughout the year, preferably in AUTO
mode.
Close all windows and the sunroof when
the air conditioning is on to ensure
satisfactory operation.
Use of air recirculation
The air conditioner/heater system is
supplied with fresh air via an intake flap.
Closing the flap causes the air inside the
vehicle to be recirculated. This helps to
prevent unpleasant odours from being
drawn into the vehicle and also to
improve the performance of the air
conditioner in very hot conditions.
However, the use of recirculated air will
cause screen misting after a short period
and should only be used as necessary.
