HEATED SCREENS AND DOOR
MIRRORS

The front screen heater (F) and
the rear screen heater (R) may be
switched on and off in any mode,
including system off, but only
operate when the engine is

running. The door mirror heaters are also
controlled by the rear screen heater
button.

The front screen heater (where fitted)
switches off automatically after
four minutes. The rear screen and door
mirror heaters switch off automatically
after ten minutes.

The windshield heaters may be manually
deselected during the time-out period
using the buttons.

In cold ambient conditions, at the start of
a journey, the front and rear screen
heaters will switch on automatically for
the timed period.

Where a front screen heater is not fitted,
the windshield has a wiper park zone
heater which operates automatically with
no manual control.

Note: The top three lines of the rear
screen pattern are a concealed antenna

AIR CONDITIONING

Touch the A/C button to
switch the air conditioning on
or off.

The air conditioning system is controlled
automatically in AUTO mode. Deselecting
A/C cancels AUTO mode.

The air conditioning system is also
switched on automatically in defrost
mode (DEF) but cannot be deselected.

BLOWER SPEED

Set the blower speed as required
using the rocker button. Blower
speed is shown as a series of bars
on the touch-screen.

If the blower speed is changed while a
non-climate control touch-screen is
displayed, a pop-up display showing the
blower speed bars will appear for a short
period.

When operating in AUTO mode, blower
speed is controlled automatically (but not
displayed) and any adjustment of the
button will cancel AUTO mode.

Note: In AUTO mode, the blower will only
operate at low speed until the engine is
warm, if heating is required in the vehicle.

BLOWER MUTE

To reduce the interior noise
level, the blower speed may
be quickly reduced to a preset
level by touching the Mute
button.

Selecting Mute will cancel AUTO mode,
but touching the Mute button again will
return operation to the previous state.

When JaguarVoice is fitted, the climate
control system will automatically prevent
any increase in blower speed while
speech commands are given.

Note: The Mute function should only be
used for short periods, as it reduces the
efficiency of the climate control system.

MANUAL AIR DISTRIBUTION

Air distribution is automatically controlled
in AUTO and defrost modes.

Touch one of the four air distribution
buttons on the screen to cancel the
current mode and select manual
operation.

The air distribution options are:

Airflow directed at face
level only; select to cool
the interior.
Airflow distributed to the
face and feet.
Airflow directed to feet
level; select to heat the
interior.
Airflow distributed to the
windshield and feet; select
to prevent or remove light
misting and when heating
the interior.

With the blower switched off, the fresh
airflow results from the forward motion of
the vehicle (ram air mode).
