To change the salon filter on Mitsubishi Padero 3, do the following:
1) Open the bottom bar.
2) On the two sides of the bar, find the latches and push them down.
3) The glove compartment opens completely down and finds the plastic panel.
4) Unscrew the two thumbscrews and remove the cover from the panel.
5) The old filter and set a new filter.
(6) All back up.
For Montero 3, the procedure is slightly different because the particulate filter does not have to be stacked on it. So you need to use the knife to cut the hole in the plastic panel, clean the entire cavity from the debris and dust, and put the filter in a niche. Secure the filter with two smores.
