Air conditioning: information and advice on use

Advice on use

In some situations (air conditioning off, air recirculation activated, ventilation speed at zero or low etc.), you may notice that condensation starts to form on the windows and windscreen.
If there is condensation, use the "Clear View" function to remove it, then use the air conditioning in automatic mode to stop it forming again.
WARNING
Do not add anything to the vehicle’s ventilation circuit (for example, to remove bad odours).
There is a risk of damage or of fire.

Maintenance

Refer to the maintenance document for your vehicle for the inspection frequency.
Tip
Use the air conditioning system regularly, even in cold weather, running it at least once a month for approximately 5 minutes.

Fuel consumption

You will normally notice an increase in fuel consumption (especially when driving in town) when the air conditioning is operating.
For vehicles fitted with air conditioning with no automatic mode, switch off the system when it is not required.
Advice for reducing consumption and helping to preserve the environment
Drive with the air vents open and the windows closed.
If the vehicle has been parked in the sun, open the doors for a few moments to let the hot air escape before starting the engine.

Operating faults

As a general rule, contact your approved dealer in the event of an operating fault.
  • Reduction in de-icing, demisting or air conditioning performance.
This may be caused by the cabin filter cartridge becoming clogged.
  • No cold air is being produced.
Check that the controls are set correctly and that the fuses are sound. Otherwise, switch off the system.

Presence of water under the vehicle

After prolonged use of the air conditioning system, it is normal for water to be present under the vehicle. This is caused by condensation.

Refrigerant fluid

The refrigerant fluid circuit (of which some components are hermetically sealed) may contain fluorinated greenhouse gases.
Depending on the vehicle, you will find the following information on label A affixed inside the engine compartment.
The presence and location of the information on label A depends on the vehicle.
