Nissan X-Trail 2024 Owners Manual
10.11. Air cleaner
To remove the filter, release the lock pins (1) and pull the unit upward (2).
The dry paper type filter element may be cleaned and reused. Replace the filter according to the maintenance schedule shown in a separate maintenance booklet. When replacing the filter, wipe the inside of the air cleaner housing and the cover with a damp cloth.
Operating the engine with the air cleaner filter off can cause you or others to be burned. The air cleaner filter not only cleans the intake air, it also stops flame if the engine backfires. If the air cleaner filter is not installed and the engine backfires, you could be burned. Never drive with the air cleaner filter off. Be cautious working on the engine when the air cleaner filter is off.
Never pour fuel into the throttle body or attempt to start the engine with the air cleaner removed. Doing so could result in serious injury.
