Health and Safety
!WARNING:
1. Many liquids and other substances used in vehicles are
poisonous and should never be
consumed and must be kept away
from open wounds.
These substances include anti-
freeze, brake fluid, fuel,
windscreen washer additives,
lubricants and various adhesives.
2. The presence of any unusual fumes (for example; petrol or
exhaust fumes) in the passenger
compartment and/or luggage
compartment should be corrected
immediately by a Jaguar Retailer.
If you must drive under these
conditions do so only with all
windows fully open.
3. By operating other electronic equipment (for example; a mobile
phone without an exterior
antenna) electro-magnetic fields
can cause malfunctions of the
vehicle electronics.
Therefore, you should observe the
instructions of the equipment
manufacturers. 4. Any modifications to the fuel
system not specifically designed
for this Jaguar are prohibited.
Such modifications in some
circumstances could result in a
fire. All service actions must be
entrusted to a Jaguar Retailer.
5. Alterations to the electrical system, including the fitting of
accessories not designed for this
Jaguar, will cause damage to the
electrical circuits and systems.
In some circumstances this could
result in a malfunction or fire.
All accessory work should be
entrusted to a Jaguar Retailer.
6. No attempt should be made to repair a fuse that has blown.
Always install a new fuse of the
correct amperage. Failure to
comply with the above may cause
a fire hazard or create serious
damage elsewhere in the
electrical circuit.
7. Avoid contact with battery acid which is poisonous and corrosive.
Acid will cause burns to the skin
as well as to the eyes. In the event
of skin or eye contamination,
wash the affected area with water
thoroughly. Seek immediate medical attention when eye
contact has occurred.
8. Do not disconnect any pipes in the air conditioning refrigeration
system. A refrigerant is used
which can cause blindness if
allowed to contact the eyes.
If refrigerant should contact the
eyes or skin, wash the eyes or
affected area with cold water for
several minutes. Do not rub.
As soon as possible thereafter,
obtain treatment from a doctor or
eye specialist.
9. When working within the engine compartment, take care to avoid
contact with moving parts and hot
components.

California to cause cancer and
birth defects or other
reproductive harm.

Before Driving 3 - 17
Occupancy sensing
The front passenger seat is monitored by ultra-sonic sensors
(shown above) and a seat weight sensor to determine the
presence, weight and position of the front passenger. In certain
conditions, e.g. where no passenger is present, the appropriate
air bags will be deactivated. In a collision these air bags would
not be deployed. Note:
The occupancy sensing system is designed to confirm that
a front passenger is properly seated as recommended:
• Always sit centrally in the seat, remaining in contact with the seat back which for comfort should be rearwards of the
vertical position.
• Adjust the seat to be as far back from the fascia as practical.
• Always wear seatbelts.
The seat adjustment controls are described on page 3 - 3.
!WARNING:
It is important that the passenger position sensors
(see illustration) are not obscured in any way which could
affect air bag deployment, e.g. fitting non-approved
accessories.

3 - 18 Before Driving
Air bag de-activation warning light
(YELLOW)
The PASS AIR BAG OFF warning light on
the passenger fascia is associated with the
deployment conditions for front seat
passenger air bags only.
• The warning light will NOT be lit if the seat is empty and the front air bag will
not be activated.
• The warning light will NOT be lit if the seat is occupied by a larger child or
adult. The front air bag will be
activated and will be deployed in the
event of a frontal impact. • The PASS AIR BAG OFF warning light
WILL be lit if the seat is occupied by,
for example, a small child and in this
case the front air bag will not be
activated.
• If the passenger adopts a posture (e.g. leaning very far forward) which
could cause injury from an inflating
air bag, the PASS AIR BAG OFF
warning light WILL be lit and the front
air bag will not be activated.
Note: Whenever the yellow PASS AIR
BAG OFF warning light on the passenger
fascia is illuminated, the front passenger
air bag will not be deployed in the event
of an impact.

4-10 On the Road
Audible Warnings
Various sounds are produced for warning and notification purposes as follows:
Hazard or Condition Remedy/chime or tone
Air bag system failure. A tone sequence is repeated five times. Report the fault to a Jaguar Retailer as
soon as possible.
External lights remain ON when the driver’s door
is opened. A chime will sound for 10 seconds as a warning that the lights are on when
the ignition is off and the drivers door is opened. Switch lights off.
Note:
The chime will not sound if the switch is in Autolamp position.
Key in ignition switch. A chime will sound if the key has been left in the ignition and the driver’s
door is opened after the ignition has been switched off or turned to
position ‘I’.
Hazard warning indicators ON. A ticking will sound until the hazard indicators are switched OFF.
Vehicle armed. This warns that the alarm will sound shortly unless the system is disarmed by
either pressing the unlock button on the key transmitter or by placing the key
in the ignition switch.
Left or right direction indicators ON. If the switch has not turned itself OFF, switch the turn indicator OFF when
the manoeuvre is completed. A ticking will sound until the indicators are

Memory 1, 2 or 3 configuration saved. A short tone as the memory selection is saved.

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.

4-58 On the Road
Vehicle Suspension
This vehicle is fitted with a fully
automatic air suspension system.
It ensures that the vehicle is always at the
correct ride height with varying load
conditions, including luggage
compartment load or when towing.
The system will automatically adjust the
amount of air in the springs to level the
vehicle. Air is supplied either from an air
reservoir or a compressor.
The compressor will run periodically to
refill the reservoir.
Changes in ambient temperature will also
have an effect on vehicle height when the
vehicle is parked.
Caution:
1. Do not overload the vehicle. Vehicle load weights are shown
on page 8 - 4.
2. A slight air loss is expected over time causing the vehicle to lower,
so do not store or place anything
under the vehicle if it is to be left
for an extended period. Speed lowering
When driving at motorway speeds,
the system will lower the vehicle to
improve aerodynamics and vehicle
stability. The suspension will
automatically return the vehicle to the
normal height when the vehicle slows.
Caution: Speed lowering is
undesirable when towing.
Only Jaguar approved towing
equipment will not allow this feature.
Warning messages
If the message ‘VEHICLE TOO LOW’ is
displayed when the ignition is switched
on, start the engine and wait for the
suspension to raise. The vehicle should
not be driven until the message is
cleared.
If the message ‘VEHICLE TOO LOW’ is
displayed when driv
ing, restrict the
vehicle speed and wait for the system to
regain the correct height and the message
will then clear. If the message is displayed
frequently, it is advisable to inform your
Retailer to have the system attended to.
If the message ‘AIR SUSPENSION FAULT’
is displayed at any time, drive with
caution. Have the vehicle checked by a
Retailer at the earliest opportunity.
Note: If your vehicle needs to be
recovered by a roadside emergency
service ensure that the vehicle is securely
lashed by the wheels and NOT the body.

On the Road 4 - 65
Fuel capacity
Avoid the risk of running out of fuel and never intentionally
drive the car when the fuel gauge indicates that the tank is
empty. When refuelling your vehicle after the fuel gauge reads
empty, you may not be able to add the fuel quantity shown
below to the tank as there will be a small reserve remaining in
the tank.Fuel Economy
The following tips not only lead to greater fuel economy but also
reduce air pollution causing less environmental damage:
• Try to avoid using the car for short journeys – this will lead
to greater fuel economy and reduce wear on the engine.
• Plan ahead – choose uncongested routes, combine car trips and share cars where possible.
• Drive off as soon as possible after starting a cold engine – do not leave the engine idling until it has warmed up.
• Drive smoothly and efficiently – harsh acceleration and heavy braking have a significant effect on fuel
consumption – driving more smoothly saves fuel.
• Slow down – driving at high speeds significantly increases fuel consumption.
• Switch off – sitting stationary is zero miles per gallon, switch
off the engine when it is safe to do so.
• Unnecessary weight – do not carry unnecessary weight and remove roof-racks when not in use.
• Regular servicing keeps the engine at best efficiency.
• Ensure that tyres are inflated to the correct pressure for the journey.
• Use air conditioning and all vehicle electrical devices sparingly – all increase fuel consumption.
• Check your fuel consumption – it will help you get the most from your car and any significant change in consumption
may indicate a vehicle fault.

Catalytic Converters
A few precautions on the use of vehicles
fitted with catalytic converters are
necessary. These are:
1. In order to maintain the efficiency of the emission control system it is
essential that unleaded fuel is used.
Use of leaded fuel will seriously
damage the catalytic converters.
2. Heavy impact on the converter casings must be avoided.
3. The engine settings must not be altered; they have been established to
ensure that the vehicle will comply
with stringent exhaust emission
regulations. Incorrect engine settings
could cause unusually high catalytic
converter temperatures and thus
result in damage to the converter and
vehicle. If adjustment to the settings is
considered necessary, this should be
performed by a Jaguar Retailer. 4. A correctly tuned engine optimises
exhaust emissions, performance and
fuel economy and it is recommended
that the vehicle is regularly
maintained.
5. Do not continue to operate the vehicle if any engine malfunction is evident;
malfunctions should be rectified
immediately. For instance, misfire,
loss of engine performance, excessive
oil consumption or engine run-on may
lead to unusually high catalytic
converter temperatures and may
result in damage to the converters and
vehicle.
6. The use of catalytic converters increases exhaust system
temperatures, therefore, do not
operate or park the vehicle in areas
where combustible materials such as
dry grass or leaves may come into
contact with the exhaust system. 7. Do not run the engine with either a
spark plug lead disconnected or a
spark plug removed. Do not use any
device that requires an insert into a
spark plug hole in order to generate air
pressure e.g. tyre pump, paint spray
attachment etc., as this could also
result in catalyti c converter damage.
8. The vehicle is designed for normal road use. Below are examples of abuse
which could damage the catalytic
converters and vehicle. These may
lead to a dangerous condition due to
excessively high catalytic converter
temperatures.
• Competition or off-road use.
• Excessive engine speed.
• Overloading the vehicle.
• Switching off the engine whilst in gear.

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.

5 - 4 Climate Control
In AUTO mode, the air intake flap is
controlled automatically. If required,
air recirculation may be manually
selected for either a short or indefinite
period.
Air Recirculation
Timed air recirculationPress the button briefly to select
timed air recirculation.
The fresh air intake is opened
and the button LED extinguished at the
end of the time out period.
Latched air re circulation
Press and hold the button for a
few seconds to select latched air
recirculation. Selection is
indicated by the scre en symbol and two
beeps.
Selecting latched air recirculation cancels
AUTO operation.
To deselect latched air recirculation,
press the recirculat ion button again,
or select AUTO.
!WARNING:
To prevent humidity build up inside
the vehicle and possible screen
misting, avoid driving with the air
conditioning system off or with
manual air recirculation selected for
prolonged periods.
General Points
To ensure the satisfactory operation of
the climate control system, note the
following points:
• Ensure that the external grille at the base of the windscreen, which
provides fresh air for the climate
control system, is kept clear of leaves,
snow or obstructions.
• A solar sensor is mounted on the centre top of the fascia, as shown
opposite ( A) . E n s u r e t h a t this sensor is
not covered.
• Temperature and humidity sensors are located behind the small grille ( B).
Do not cover or obstruct the opening.
• Air ducts under the front seats supply the rear passenger footwells (see
illustration opposite). Objects or
material placed under the seats may
block or obstruct the open ducts. • The external air intake to the air
conditioner/heater system is fitted
with a filter. Ensure that the filter is
changed at the specified service
intervals to maintain efficient
operation.
• If the air conditioning system is not used frequently, it should be run
briefly at least once each week, with a
cold setting, to prevent the seals from
drying out with subsequent
refrigerant leaks.
• Moisture removed from the air by the air conditioning unit is discharged
onto the road underneath the vehicle.
After stopping, puddles of water may
form underneath the vehicle.
Air Distribution
The illustration opposite shows the
location of the air vents within the
vehicle. The airflow from the fascia face
level vents is regulated using thumbwheel
controls and adjustable direction vanes.
Air distribution between the windscreen,
fascia and floor levels is selected
automatically when operating in AUTO
mode but can be selected manually.
