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.

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, refer to Temperature
Selection.

For normal usage select AUTO mode.

AUTO MODE

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

To select automatic climate

TEMPERATURE SELECTION

Separate controls allow
the driver and passenger

Both driver and passenger temperatures
are always displayed.

Pressing the driver’s buttons to select the

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.
