Nissan X-Trail e-POWER 2023 Owners Manual
8.2.3. Petrol Particulate Filter (GPF) (where fitted)
Your vehicle is equipped with a Petrol Particulate Filter (GPF) as a 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 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 appears in the vehicle information display.
When the [Exhaust Filter/Self Clean in Progress] message appears in the vehicle information display, the engine speed is increasing automatically to burn carbon particles. When this message is displayed, keep an appropriate driving, provided that legal and safety conditions allow, until the message is turned off.
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 (ICC) (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).
