NOTE: The air conditioning will not operate without the engine

running nor when the blower switch is turned to position 'O'.

NOTE: Because the system dehumidifies the air supplied to it,

surplus water is produced and expelled via drain tubes beneath the car.

This may result in a small pool of water forming under the car when

stationary and is not a cause for concern.

Heating & Ventilation

Operating advice

Heater bypass control

The following procedures will enable you to gain maximum

benefit from the heating and ventilation system. However, because

the system uses heat from the engine to warm the air, full heating

will not be available until the engine reaches its normal operating

temperature.

To achieve maximum demisting/defrosting

• Select ‘windscreen’ on the air distribution control.

• Turn the air temperature control(s) to the RED segment.

• Turn the blower switch to ‘IV’.

• Select ‘IV’ on the blower switch (adjust as required).

• towards the WHITE spot to close the bypass.

• Switch on air conditioning (where fitted).

If the air distribution control is set to foot, screen or window vents:

• Heater bypass closed - all air flow is prohibited.

• Heater bypass open - unheated (fresh) air supply only.

If the air distribution control is set to face or foot and face vents:

• Heater bypass closed - heated air supply (temperature as heater

• Heater bypass open - a blend of heated and unheated air (which

has bypassed the heater) providing a cooler output.

Heating & Ventilation

Particle/pollen filter/odour filter*

AUTOMATIC TEMPERATURE CONTROL (ATC)*

A particle filter will help to keep the car interior free from pollen

and dust. To remain fully effective, the filter should be replaced

every 2 years or 50,000 km, at the time of an oil service or

inspection.

TEMP

The particle filter can be combined with an odour filter to help

inhibit the smell of traffic fumes. The combined filter requires

replacement every 12 months or 25,000 km.
