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

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.

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.

5 - 6 Climate Control
Front Climate Controls
The climate control functions are selected
by push buttons and a rotary control.
When a button is pressed, selection of
the function is confirmed by a beep; most
buttons also have an illuminated LED.
Many system functions also have graphic
symbols displayed on the LCD (liquid
crystal display) screen.
Automatic control (AUTO) may be
overridden at any time. Defrost/demist
operation is available and also manual
selection of blower speed,
air distribution, recirculation,
air conditioning and windscreen heating.
Panel illumination
With the exterior lighting switched on or
Autolamps selected at night, the graphics
on the panel controls are illuminated by
low level backlighting.
In countries with daytime runnin g lamps,
the panel illumination will not be on
during daytime if the headlamp switch is
off or in Autolamp position unless it is
dark and the autolamp selects the
headlamps on.
The illumination level is adjusted by the
common instrument panel dimmer
