Diesel vehicles equipped with a Diesel Particulate Filter (DPF) have more efficient emissions control. The particles in the exhaust gases are collected in the exhaust filter during normal driving.

Cleaning of the exhaust filter, also known as regeneration, occurs automatically, approximately every 300 to 900 km depending on driving conditions, and requires the engine to reach normal operating temperature.

The self-cleaning takes place when the vehicle is driven steadily at speeds between 60 km/h to 112 km/h (40 mph to 70 mph). This process normally takes 10-20 minutes. It is possible for self-cleaning to occur at lower vehicle speeds, but the process may take a little longer at a 50 km/h (30 mph) average speed.

Exhaust filter self-cleaning:

Some driving conditions, e.g., frequently driving short distances, in slow-moving traffic, or in cold weather may not provide sufficient opportunity to begin the exhaust filter self-cleaning automatically. When this occurs, a warning icon is displayed in the message centre, depending on status, as follows:

  • Amber: Exhaust filter self-cleaning is required. Driving above 60 km/h (40 mph) for 20 minutes should clean the filter.


    Failure to follow the above driving approach to enable filter self-cleaning, may result in reduced vehicle performance. The amber exhaust filter icon is eventually replaced by a red exhaust filter icon, and the filter may need to be replaced.

  • Red: The exhaust filter is full. Contact a retailer/authorised repairer as soon as possible.


A small increase in fuel consumption may be noticed temporarily during exhaust filter self-cleaning.


If diesel fuel with high sulphur content is used regularly, the exhaust may emit a cloud of smoke at the start of the self-cleaning process. The sulphur deposit being burnt off and is no cause for concern. If possible, only use low sulphur diesel fuel.
