Nissan X-Trail 2024 Owners Manual
7.3.2. Petrol Particulate Filter (PPF) (where fitted)
Your vehicle is equipped with a Petrol Particulate Filter (PPF) as a part of the emission control system.
The PPF 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 PPF are burned-off regularly, thus emptying the filter from carbon particles. In this way, the PPF is “regenerated” and again fully operational to filter the carbon particles from the exhaust gas as intended.
Under certain driving conditions, the PPF may become saturated/clogged because these driving conditions prevent automatic regeneration of the filter. In this case, a message appears in the vehicle information display.
When the [Exhaust Filter/Self Clean in Progress] message appears in the vehicle information display, provided that legal and safety conditions allow, the vehicle should be driven at a speed of over 60 km/h (37 MPH) until the message is no longer displayed.
During the regeneration process, the engine speed may increase and driveability may change. You may also notice a change in the sound of the exhaust system. However, this is a normal behavior of the engine during regeneration and does not indicate a malfunction.
When the [Exhaust Filter/Self Clean in Progress] message appears, Stop/Start system, cruise control (where fitted), Intelligent Cruise Control (where fitted) and ProPILOT Assist (where fitted) system may be deactivated.
If the vehicle continues to be driven with the [Exhaust Filter/Self Clean in Progress] message displayed, the GPF may become more saturated and displayed message may change to [Exhaust Filter/Maintenance Required Service now].
When the [Exhaust Filter/Maintenance Required Service now] message appears in the vehicle information display, always visit the nearest NISSAN dealer or qualified workshop as soon as possible. The Malfunction Indicator Light (MIL) may also illuminate. Extended driving with the message displayed and/or the MIL illuminated may lead to damage to the exhaust filter system.
When the [Exhaust Filter/Maintenance Required Service now] message appears in the vehicle information display, cruise control (where fitted), Intelligent Cruise Control (where fitted) and ProPILOT Assist (where fitted) system will be deactivated.
What you can do 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 (37 MPH) for an extended period of time (more than 30 minutes).
