Touch-screen Climate Control

INFORMATION

A general introduction to the
touch-screen is given in the
Touch-screen chapter of this handbook,
starting on page 275. The operating
information given here refers to the
touch-screen and other controls.

The vehicle has both driver and
passenger (dual zone) red and blue
temperature control arrow buttons.

Refer to page 191 for more information on
the rear climate control panel fitted with
the optional 4-zone system.

Controls and displays

The climate control system has its own
menu on the touch-screen. A number of
other buttons are also used for climate
control and are located around the
perimeter of the touch-screen. When a
perimeter button is pressed, selection of
the function is confirmed by a beep and,
on most buttons, illumination of a Light
Emitting Diode (LED).

An LCD screen below the touch-screen
shows the interior temperatures set by the
driver and passenger and the external
(EXT) ambient temperature.

Note: Using other systems and
touch-screen displays, such as audio or
navigation, does not affect the climate
control settings.

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.

IGNITION ON

The climate control system operates in
position II of the ignition switch.

When the ignition is switched to position
II or the engine is started, the Jaguar logo
will be displayed briefly followed by the
last touch-screen selected (e.g. radio).

The climate control system will be set to
the climate operating mode selected
previously.

CLIMATE CONTROLS DISPLAY

There are two climate control
touch-screen displays, one for the system
‘ON’ state and the other for system
‘OFF’/ram air mode. Smaller pop-up
displays appear briefly when selecting air
recirculation or adjusting the blower
speed.

Most climate functions can be selected
using the perimeter buttons without
displaying the climate touch-screen
buttons.

To select the touch-screen
display, press the CLIMATE
button.

To exit the climate control screen, select
another system function, e.g. AUDIO.

AUTO MODE

Automatic operation provides a
controlled environment over a
temperature range of 17°C (61°F) to 31°C
(89°F) and should be regarded as the
normal operating mode.

To select automatic climate
control press the AUTO button
and select the required
temperature.

The AUTO mode touch-screen is shown
above. If the touch-screen is not
displayed, press the CLIMATE button.

Front and rear screen heating and timed
air recirculation may be selected while
remaining in AUTO mode. Selecting any
other climate control perimeter button or
touch-screen button will cancel AUTO
operation.

Automatic operation cannot be
deselected using the AUTO button. To
exit AUTO mode, select another climate
mode or touch the system ON/OFF
button to switch the system off.

Set the required interior
temperature with the red
or blue arrowed buttons.

Press the red buttons to increase
temperature and the blue buttons to
decrease temperature.

The selected temperatures will appear on
the LCD screen below the touch-screen.

Pressing the driver’s buttons to select the
maximum or minimum temperature
settings causes the LCD screen to
change to HI or LO respectively and
cancels AUTO mode.

To quickly jump from HI or LO to a
convenient mid-range temperature of
23°C (73°F), press and hold AUTO for a
few seconds.

DUAL TEMPERATURE ZONES

With the Dual button
illuminated, the system
provides separate

temperature control of the driver and
passenger zones.

Touch Dual to deselect dual temperature
control; the passenger temperature will
change to that of the driver’s side. Using
the driver’s side temperature control
buttons will now change both zone
temperatures together.

To select dual temperature control, either
touch Dual or press one of the
passenger’s side temperature control
buttons.

EXTERNAL TEMPERATURE

The external (EXT) temperature is
displayed on the LCD screen.

CELSIUS/FAHRENHEIT
