Nissan Qashqai 2024 Owners Manual
7.7. Gasoline particulate filter (GPF) (where fitted)
Your vehicle is fitted with a Gasoline Particulate Filter (GPF) (or Petrol Particulate Filter) as part of the emission control system.
The GPF filters carbon particles from the exhaust gas, thus reducing the emission of soot to the environment.
Under normal driving conditions, the accumulated carbon particles in the GPF are burned-off regularly, thus emptying the filter from carbon particles. In this way, the GPF is “regenerated” and again fully operational to filter out the carbon particles from the exhaust gas as intended.
Under certain driving conditions, the GPF may become saturated/clogged because these driving conditions prevent automatic regeneration of the filter. In this case, a message is displayed in the vehicle information display.
When the [Exhaust filter maintenance See owner's manual] message is displayed, provided that legal and safety conditions allow, the vehicle should be driven at a speed of over 50 km/h (30 MPH), with gentle use of the accelerator pedal, until the message is no longer displayed.
Should the MIL come on for any reason, or if the [Exhaust filter maintenance See owner's manual] warning message continues to be displayed in the vehicle information display and will not clear, always visit a NISSAN dealer or qualified workshop as soon as possible. Extended driving with the MIL illuminated may lead to damage to the exhaust filter system.
What you can do yourself to prevent the GPF from becoming saturated/clogged:
Avoid repeated and frequent short journeys in which the engine does not reach its normal operating temperature.
Regularly drive the vehicle at speeds over 60 km/h for an extended period of time (more than 30 minutes).
