Air Vents
The temperature of the air from all vents is 
controlled by the temperature settings of the 
heater.
Rotate the thumbwheel towards the green 
indicator to open, or the white indicator to close 
the vents. Direct the air flow 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 
conditioning air distribution control is set to 
face level.
Center foot/face level vents
When the air conditioning air distribution 
control is set to either ‘Auto’ or ‘Face and Foot’ 
outlet, the temperature of the air emitted 
through the foot/face level vents can be finely 
adjusted to differentiate between foot and face 
temperature. Rotate the thumbwheel (1), 
towards the left (red indicator) for warm air and 
to the right (blue indicator) for cooler air.Side face level vents

COMFORT AIR CONDITIONING
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 conditioning, air distribution, 
blower speeds and air recirculation are adjusted 
automatically to achieve and then maintain the 
desired driving environment. Both the air distribution and blower controls 
can be operated independently to override the 
automatic setting. In this case, the appropriate 
indicator light in the ‘AUTO’ switch extinguishes 
(the circular light represents the blower, the 
rectangular light represents air distribution). 
Press ‘AUTO’ again to re-establish automatic 
operation.
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. Front seat heaters
*
Press once to operate at a high 
level, press twice to heat the seats 
at a lower level. For further 
information concerning the operation of both 
front and rear seat heaters, please refer to 
‘SEAT HEATERS*’, page 107.

3. Defrost mode
If the windshield is misting or 
covered in ice, press to activate the 
automatic defrost programme; the 
system will immediately direct its output to 
achieve maximum windshield clearing by:
•setting the blower speed and temperature to 
maximum.
•distributing air flow to the windshield only.
•deactivating the rear blower.
•deactivating air recirculation.
In addition, the rear window and windshield 
heaters will be switched on (or their timed 
operating cycle will recommence if they are 
already switched on).
Press the button a second time (or select 
‘AUTO’ or any air distribution control) to leave 
the Defrost mode.
4. Maximum air conditioning
This mode automatically activates 
the air conditioning and air 
recirculation, and sets the blower 
speed at maximum and the air distribution to 
the face level vents. This mode overrides the 
current temperature settings.
4. Park heating
After driving, it is possible to 
provide heat to the cabin by using 
residual heat from the engine - with 
the engine turned off. By pressing the MAX 
button, continued heating is available for up to 
15 minutes.5. Temperature controls
Rotate the controls 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.
The temperatures on the control surrounds 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. 
6. Blower control
Rotate clockwise to increase and anti-clockwise 
to decrease airflow from the vents. 
7. Air distribution control
Press the appropriate button to select the 
desired distribution setting: 
Foot level vents
Face level vents
Windshield and side window vents
More than one setting can be selected at once, 
to get the desired distribution.

8. Air conditioning control
With the engine running, press the 
button to manually activate the air 
conditioning, or to switch off the 
air conditioning if it has been previously 
selected (manually or automatically).
9. Air recirculation
Air recirculation prohibits 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.
NOTE: On some vehicles, there is also a remote 
air recirculation button on the steering wheel. 
This button is a simple on/off button and does 
not incorporate the automatic recirculation 
feature (see ‘REMOTE AIR RECIRCULATION’, 
page 108).
Press the button once to activate automatic 
recirculation. This feature automatically 
activates air recirculation when sensors fitted to 
the vehicle detect high levels of air pollution, 
therefore preventing the ingress of fumes into 
the vehicle (in a traffic queue, for example).
Press the button a second time to activate air 
recirculation. 
Press the button a third time to deactivate air 
recirculation.
Air recirculation also significantly influences 
the dehumidifying and cooling performance of 
the air-conditioning system. Therefore, in Auto 
mode, air recirculation is regulated 
automatically to enable the air-conditioning 
system to achieve its optimum performance.
NOTE: Prolonged recirculation may cause the 
windows to mist. 10. Heated windshield*
Press to operate, the indicator light 
in the switch will illuminate 
whenever the windshield heater is 
on.
11. Heated rear window
Press to operate; the indicator light 
in the switch illuminates whenever 
the window heater is on.
CAUTION: DO NOT stick labels over the heating 
elements on the rear window, and DO NOT 
scrape or use abrasive materials to clean the 
inside of the rear window.

USING YOUR HEATER
Fresh air enters the heater unit through the 
grille in front of the windshield and stale air is 
drawn out through vents in the rear of the 
vehicle. 
The following examples of basic heater settings 
are intended as a general guide; the air 
distribution, temperature and blower controls 
can then be further adjusted to suit your 
comfort requirements. Always remember that 
full heating is not available until the engine has 
reached its normal operating temperature.
Maximum heating
Set the temperature control to maximum and 
the air conditioning air distribution control to 
‘AUTO’, with the blower at the slowest speed 
(position 1) until the temperature gauge 
indicates that the engine is warming up - the 
blower speed can then be increased. Set the 
center face ventilation temperature control fully 
towards the red indicator.
Demisting/defrosting
Switch on the air conditioning and the 
windshield heaters, then set the temperature 
and blower controls to maximum. Set the air 
conditioning air distribution control to ‘all air to 
windshield’, to obtain the maximum flow of 
heated air from the windshield and side window 
vents. When defrosting, switching on air 
recirculation will help, but remember to switch 
off air recirculation as soon as defrosting has 
completed, to avoid windshield misting.Maximum ventilation
Set the temperature control to your preferred 
interior temperature. Switch on the air 
conditioning and select air recirculation. Set the 
air distribution control set to ‘Air to face vents’. 
Ensure the face level vents are open and set the 
center face vent temperature control fully 
towards the blue indicator. Adjust the blower 
speed to maximum.
Opening a window or the sunroof may improve 
ventilation. Remember; do not open a window 
or the sunroof, if the air conditioning is 
operating.

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 windshield 
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.
INDEPENDENT VENTILATION CONTROL
The independent ventilation control attains a 
more comfortable temperature in the 
passenger compartment prior to entry through 
use of the Timer Preset feature, or, while inside 
the vehicle by use of Direct Mode. 
The ventilation feature operates without 
running the vehicle’s engine.
It can be operated manually or programmed to 
switch on at a preset time. 
Timer Preset mode
An electronic control unit checks for an ambient 
exterior temperature of 16
oC before 
determining if ventilation is required.
If the temperature is above 16
oC, the unit will 
activate the independent ventilation until the 
interior temperature matches the exterior 
ambient temperature.
The system will automatically shut down after 
30 minutes. See the Audio and Navigation 
handbook or the In-Car Entertainment 
handbook for further details.
