h

ave   an   adverse   effect   on   the   per formance  
o

f   the   air   conditioning   system   and   generate

dours.The start of saturation of the particle filter is
indicated
  by:
On a new vehicle, the first operations of
regeneration   of   the   particle   filter   may   be  
a

ccompanied   by   the   smell   of   "burning",  
w

hich   is   per fectly   normal.
Following
  prolonged   operation   of   the  
v

ehicle at very low speed or at idle,
you
  may,   in   exceptional   circumstances,
