Ventilation system pollen filter renewal (Every 20 000 miles or 2 years)
Routine maintenance and servicing / Ventilation system pollen filter renewal (Every 20 000 miles or 2 years)


1 The air entering the vehicleТs ventilation system is passed through a very fine pleatedpaper air filter element, which removes particles of pollen, dust and other airborne foreign matter. To ensure its continued effectiveness, this filterТs element must be renewed at regular intervals.

2 Remove the left-hand side windscreen wiper arm (Chapter 12).

3 Prise off their trim caps, then unscrew the two screws securing the windscreen edge of the cowl grille panel; open the bonnet and remove the remaining three retaining screws (see illustration).

6 Wipe out the ventilation system intake and the filter housing, removing any leaves, dead insects etc.

7 If carrying out a routine service, the element must be renewed regardless of its apparent condition. If you are checking the element for any other reason, inspect its front surface; if it is very dirty, renew the element. If it is only moderately dusty, it can be re-used by blowing it clean from the rear to the front surface with compressed air. Because it is a pleated-paper type filter, it cannot be washed or re-oiled. If it cannot be cleaned satisfactorily with compressed air, discard and renew it.

Warning: Wear eye protection when using compressed air!

8 Refitting is the reverse of the removal procedure; ensure that the element and housing are securely seated, so that unfiltered air cannot enter the passenger compartment.
