Ford Focus Owners Manual: Diesel particulate filter (DPF)
The DPF forms part of the emissions reduction systems fitted to your vehicle.
It filters harmful diesel particulates (soot) from the exhaust gas.
Regeneration
WARNING:
Do not park or idle your vehicle over dry leaves, dry grass or other combustible materials. The DPF regeneration process creates very high exhaust gas temperatures and the exhaust will radiate a considerable amount of heat during and after DPF regeneration, and after you have switched the engine off. This is a potential fire hazard.
Unlike a normal filter which requires periodic replacement, the DPF has been designed to regenerate, or clean itself to maintain operating efficiency. The regeneration process takes place automatically. However, some driving conditions mean that you may need to support the regeneration process.
If you drive only short distances or your journeys contain frequent stopping and starting, occasional trips with the following conditions could assist the regeneration process:
• Drive your vehicle, preferably on a main road or motorway, for up to 20 minutes avoiding prolonged idling, but always observing speed limits and road conditions.
• Do not switch off the ignition.
• Use a lower gear than normal to maintain a higher engine speed during this journey, where appropriate.
