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 
and do not defrost the rear screen.

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.

screen. The touch-screen will change to 
the system off/ram air climate control

With the climate control system switched 
off, air recirculation is automatically

air distribution to face level automatically

Any of the other air distribution modes

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