Air ConditioningVENTILATION
The ventilation system provides fresh or heated 
air to the interior of the vehicle from the air 
intake grille in front of the windscreen. 
NOTE: Always keep the air intake grille clear of 
obstructions such as leaves, snow or ice.
Air outlets are provided to the windscreen, face 
and feet - the location of those vents is shown 
in the illustration above. The temperature of the 
air supplied to the vents is controlled by the 
heater.
NOTE: Vent (1) is designed to keep the audio 
unit cool, there is no air flow from this vent.
Information concerning the operation of the air 
conditioning system, appear on the following 
pages.Face level vents
Each vent can be opened or closed by rotating 
the thumbwheel: left to open, right to close. 
Direct the flow of air by moving the control in 
the center of the louvres.
To ensure best ventilation and minimum noise, 
the vents should be fully open when the air 
distribution control is set to face level.

AIR CONDITIONING CONTROLS
The air conditioning system features automatic 
temperature and air distribution control, which 
is programmed to maintain optimum levels of 
comfort within the vehicle in all but the most 
severe climatic conditions.
While the controls can be adjusted manually to 
satisfy individual requirements, allowing the 
system to function automatically (in Auto 
mode) is by far the simplest method of 
operation for the owner and is preferable in 
most operating conditions. 
1. Auto mode In Auto mode, air distribution and blower 
speeds are adjusted automatically to achieve 
and then maintain the desired temperature.      
(An enclosed area in the center of the display 
will show ‘AUTO’ together with the air 
distribution and blower speed settings).
Both the air distribution and blower controls 
can be operated independently to override the 
automatic setting. In this case, the relative 
symbols will move outside the enclosed area in 
the center of the display to indicate that they are 
no longer being controlled automatically.
NOTE: If the air distribution and blower controls 
are operated independently, the system may 
not be able to achieve or maintain the required 
temperature settings.

2. Temperature controls 
Operate the rocker switches on either side of 
the display to set the required temperature for 
the corresponding side of the passenger 
compartment (left hand switch for the left side 
of the vehicle, and right hand switch for the 
right side).
Temperatures above 82°F (28°C) and below 
61°F (16°C) cannot be set. Above or below 
these maximum and minimum settings ‘HI’ or 
‘LO’ will appear in the display.
The temperatures shown on the display are 
relative, target, temperatures only and are not 
reflective of any specific temperature measured 
within the vehicle interior. 
NOTE: The system will not achieve 
temperatures on the passenger side of the 
vehicle that are more than 9°F (5°C) greater or 
less than the temperature set for the drivers 
side. 
3. Defrost mode
If the windscreen is misting or 
covered in ice, press this button; 
the system will immediately direct 
its output to achieve maximum screen clearing 
by:
•setting the blower speed to maximum
•distributing air flow to the screen only.
In addition, the rear and front screen heaters
* 
will be switched on (or their timed operating 
cycle will recommence if they are already 
switched on).
NOTE: The temperature and blower speed 
controls can be adjusted and air recirculation 
selected manually if required. 
Press the ‘SCREEN’ button a second time (or 
select ‘AUTO’) to leave the Defrost mode - the 
system will default automatically to Auto mode.4. Economy mode
Press the ‘Econ’ button to operate 
(the display shows ‘ECON’).
In economy mode, the air conditioning 
compressor is switched off and the system 
functions as a conventional heating and 
ventilation system. This reduces the load on the 
engine, thereby reducing fuel consumption.
Select Economy mode whenever air 
conditioning is not required i.e. in cold weather 
when the external temperature is lower than the 
temperature required for the passenger 
compartment.
The air distribution, blower and recirculation 
controls can be operated independently.
Pressing the ‘Econ’ button a second time will 
switch the air conditioning compressor on and 
return the system to Auto mode.
NOTE: In Economy mode, it is possible to 
switch the blower off (no segments showing in 
the display). 
5. On/off button 
Press to switch on or off.
When switching on, note that the 
system automatically recalls the mode and 
control settings that were last used.
6. Blower button
Press the button to adjust the 
blower speed. The blower speed 
increases incrementally with each 
press of the button, until maximum fan speed is 
reached (the display shows five segments and 
the word ‘MAX’). 
Once the maximum fan speed has been 
reached, another press of the button returns the 
blower to its slowest speed (one segment 
shows in the display).

7. Air distribution control
Press the button to adjust. Air 
distribution changes incrementally 
with each press of the switch in the 
following sequence: 
Face level vents
Foot and face level vents
Foot level vents
Foot level, windscreen and side window 
vents
Windscreen and side window vents
A further operation of the button returns to the 
start of the sequence.
NOTE: If the button is pressed for more than 
one second, air distribution will automatically 
default to foot and face level vents. 
8. External temperature
Press the button to display. The 
external temperature is displayed 
for approximately 6 seconds, after 
which the display reverts to its previous state. 
NOTE: While the air conditioning system is 
switched off, the external temperature can be 
displayed briefly by pressing the button. 9. Air recirculation
The air recirculation feature can be 
used to prohibit the entry of air 
from outside the vehicle, 
alternatively recirculating the air inside the 
vehicle instead. This is useful to prevent the 
entry of traffic fumes.
The feature also significantly influences the 
dehumidifying and cooling performance of the 
air-conditioning system. Therefore, in Auto 
mode, air recirculation is controlled 
automatically to enable the air-conditioning 
system to achieve its optimum performance.
However, the feature is also manually 
selectable in Auto, Defrost and Economy 
modes, as follows:
In Auto mode:
•Press the button briefly (display shows 
recirculation symbol):
Air recirculation operates until the control is 
pressed a second time to switch off.
•Press and hold for 2 seconds (two beeps 
will sound, display shows recirculation 
symbol):
Air recirculation operates for a pre-timed 
period of 4-6 minutes only. 
In Defrost and Economy modes: 
•Press the control briefly (display shows 
recirculation symbol): 
Air recirculation operates for a pre-timed 
period of 4-6 minutes only. 
•Press and hold for 2 seconds (two beeps 
will sound, display shows recirculation 
symbol):
Air recirculation operates until the control is 
pressed a second time to switch off.
NOTE: Prolonged recirculation may cause the 
windows to mist.

Temperature conversion (°F - °C)
The temperature displays can be converted to 
or from Fahrenheit and Centigrade, as follows:
•Press and hold the air recirculation button.
•At the same time, press and hold the on/off 
button for 3 seconds.
•A ‘beep’ will sound to indicate that the 
conversion has taken place. 
Rear air conditioning controls
Some vehicles are equipped with a 
supplementary air conditioning system, which 
supplies cooled, dried air to the rear passenger 
compartment through air vents set into the rear 
roof lining. The rear air conditioning will only 
operate when the front air conditioning is 
switched on. In all other respects, however, it is 
controlled independently using the controls set 
into the roof lining. To operate:
1.With the front air conditioning switched 
on, press the on/off switch in the rear air 
conditioning control panel (illustrated).
2.Adjust the slider control to increase or 
reduce the air conditioning fan speed.
3.Always switch off the rear air conditioning 
after use, otherwise operation will start 
automatically again when the vehicle is 
next used.
During cold weather, when the air conditioning 
is not in use, the rear air conditioning controls 
can be used to supply recirculated air to the rear 
passenger compartment.GENERAL NOTES
•For optimum operating efficiency, ensure all 
the air vents (including those in the rear of 
the vehicle) are open.
•For the automatic temperature control 
system to function efficiently, all windows 
(and the sunroof) should be closed, and the 
air intake vents free from ice, snow, leaves 
or other debris.
•In very humid conditions, slight screen 
misting may be experienced when the air 
conditioning system is turned on. This is a 
natural occurrence on most automotive air 
conditioning systems. It is not a fault and 
misting will clear after a few seconds once 
the air conditioning system is operating.
•The air conditioning compressor will not 
function unless the engine is running.
•Surplus water produced by the 
dehumidifying process is expelled from the 
system via drain tubes beneath the vehicle. 
This may result in a small pool of water 
forming on the road when the vehicle is 
stationary and is not a cause for concern.
•If desired, the systems audible information 
chimes can be deactivated, as follows:
1. Press ‘Auto’ button and hold.
2. Press ‘On/off’ button and hold pressed for 
3 seconds, then release.
3. Press ‘On/off’ button again for a further 3 
seconds, and release.
4. Release ‘Auto’ button.
