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.
