DS 3: Heating and Ventilation / Advice

Using the ventilation and air conditioning system

• To ensure that air is distributed evenly, keep the external air intake grilles at the base of the windscreen, the nozzles, the vents, the air outlets and the air extractor in the boot free from obstructions.
• Do not cover the sunshine sensor located on the dashboard; this sensor is used to regulate the automatic air conditioning system.
• Operate the air conditioning system for at least 5 to 10 minutes once or twice a month to keep it in good working order.
• If the system does not produce cold air, switch it off and contact a dealer or a qualified workshop.

When towing a large load on a steep gradient in high temperatures, switching off the air conditioning increases the available engine power, enhancing the towing capacity.

Avoid driving for too long with the ventilation off or with prolonged operation of interior air recirculation. Risk of misting and deterioration of the air quality!

If the interior temperature is very high after the vehicle has stood for a long time in the sunshine, air the passenger compartment for a few moments. Put the air flow control at a setting high enough to quickly change the air in the passenger compartment.

Condensation created by the air conditioning results in a discharge of water underneath the vehicle. This is perfectly normal.

Servicing the ventilation and air conditioning system

• Ensure that the passenger compartment filter is in good condition and have the filter elements replaced regularly.

  We recommend using a composite passenger compartment filter. Thanks to its special active additive, this type of filter helps to purify the air breathed by the occupants and keep the passenger compartment clean (by reducing allergic symptoms, unpleasant odours and greasy deposits).

• To ensure correct operation of the air conditioning system, have it checked according to the recommendations in the Manufacturer’s service schedule.

Stop & Start

The heating and air conditioning systems only operate when the engine is running.

Temporarily deactivate the Stop & Start system to maintain a comfortable temperature in the passenger compartment.
