Climate Control
Introduction
This vehicle is fitted with one of the
following climate control systems:
•
Automatic climate control system with
an LCD (liquid crystal display) screen.
See page 132.
•
Automatic climate control system with
touch-screen (shared with the
navigation and audio systems).
Where this control unit is fitted, refer
to the touch-screen display handbook
for detailed operating instructions.
Each system has a unique control panel
located in the centre console above the
radio and audio controls.
General information applicable to all three
systems is given below.
Recommended Operation
Use of air recirculation
The air conditioner/heater system is
supplied with fresh air via an intake flap.
The flap may be closed to allow the air
inside the vehicle to be recirculated.
This helps to prevent unpleasant odours
from being drawn into the vehicle.
On all systems, air recirculation may be
manually selected either for an
automatically timed period or to remain
on continuously (latched recirculation).
When latched recirculation is selected,
the air conditioning will switch on
automatically to reduce condensation.
Note:
When air recirculation is selected,
the sound of the airflow will change. This
is normal.
Automatic climate control systems
With automatic climate control systems,
the air conditioning, recirculation and
other functions are fully controlled in
AUTO mode to provide optimum comfort
under most driving conditions.
It is recommended that AUTO is selected
as the normal operating mode on these
systems.
Use of air conditioning
The manual and automatic climate control
systems are fitted with air conditioning to
provide cooling and dehumidified air.
The dry airflow is also effective in
preventing misting of the windows.
It is recommended that air conditioning is
used in all climatic conditions throughout
the year, even when warm airflow is
required.
Close all windows and the sunroof when
the air conditioning is on to ensure
satisfactory operation.
Note:
Selecting air recirculation will
improve the performance of the air
conditioning in very hot conditions.
!
WARNING:
To prevent humidity build up inside the
vehicle and possible screen misting,
avoid driving with the air conditioning
system off or in manual air
recirculation for prolonged periods.

Climate Control
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.
•
Air ducts under the front seats supply
the rear passenger footwells (refer to
illustration on page 131). 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: this is
normal.
Panel Illumination
With the exterior lighting switched on,
the graphics on the panel controls are
illuminated by low level backlighting.
The illumination level is adjusted by the
common instrument panel dimmer
control.

Climate Control
Air Distribution
The illustration shows the location of the
air vents within the vehicle.
On vehicles fitted with automatic climate
control, the appropriate air distribution is
selected automatically when operating in
AUTO mode.
On all climate control systems,
the distribution of air between the screen,
fascia and floor level can be manually
selected using the panel controls.
The airflow from the fascia face level
vents is regulated using thumbwheel
controls and adjustable direction vanes.

The automatic climate control system
maintains the interior of the vehicle at the
temperature selected by the occupant.
The heat input, air conditioning,
blower speed, air intake and distribution
are adjusted automatically to maintain the
desired temperature.
Note:
It is advisable to allow the system to
stabilise before making large changes to
the temperature setting, particularly at the
start of a journey (see
Temperature
Selection
on page 133).
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.
The climate control functions are selected
by push buttons and a rotary control.
When a button is pressed, selection is
confirmed by a beep and illumination of
the button LED.
Most functions also have associated
graphic symbols displayed on the LCD
(liquid crystal display) screen.

Automatic Climate Control
To Switch the System On
The climate control system operates in
position ‘
II
’ (run) of the ignition switch.
With the ignition key turned to the run
position, the system will switch on in the
operating mode last set.
For normal usage select AUTO mode.
AUTO Mode
Automatic operation provides a
controlled environment over a
temperature range of 61°F
(17°C) to 89°F (31°C) and should be
regarded as the normal operating mode.
To select automatic climate control press
the AUTO button; the word AUTO
appears on the LCD screen to confirm
selection.
Select the required temperature.
Front and rear screen heating and timed
air recirculation may be selected in AUTO
mode. Selecting any other control will
cancel AUTO operation.
Automatic operation cannot be
deselected using the AUTO button.
To exit AUTO mode, select another mode
or press the blower control knob to switch
the system off.
Temperature Selection
Set the required interior
temperature with the red
and blue arrowed
buttons. Press the red
button to increase temperature and the
blue button to decrease temperature.
The selected temperature will appear on
the lower part of the LCD screen.
Pressing the buttons to select the
maximum or minimum temperature
settings causes the display to change
to HI or LO respectively and cancel
AUTO mode.
To quickly jump from HI or LO to a
convenient midrange temperature of 73°F
(23°C), press and hold AUTO for a few
seconds.
When AUTO is selected, the system
constantly monitors the conditions inside
and outside the vehicle. For your
maximum comfort, it is advisable to allow
the system to stabilise before making
large changes to the temperature setting,
particularly at the start of a journey.
External Temperature
The external (EXT) temperature is
displayed at the top of the screen.
Celsius/Fahrenheit Selection
Press the button to change the
scale between degrees
Celsius (°C) and degrees
Fahrenheit (°F) for the displayed
internal and external (EXT)
temperatures.
