smoke,   perfu mes,  etc.)  from  sticking   to  the   wind ows.
Contam inates  increase  the  rate  of wind ow  fogging.
Win dow  Foggin g
Wind ows will fog on  the insid e when the  hu midity insid e
the  vehicle   is  high.  This  often   occurs  in  mild   or  cool
tem peratu res  when   it’s rainy   or  hu mid.  In  most  cases
turning   on the  Air-cond itioning  (pressing   the snow flake
button)  will clear  the fog. Adjust  the  tem peratu re control,
air direction   and  blow er speed  to  maintain  comfort.
Summer   Operation
Air  cond itioned  vehicles  must  be  protected   with  a high
quality   antifreeze   coolant   during    summer   to   provid e
prop er corrosion  protection   and to  raise the  boiling point
of the  coolant  for protection   against  overheating.   A 50 %
concentration   is  recom mend ed.  Refer to  Recom mend ed
Fluids  and  Genu ine Parts  for  the  prop er coolant  typ e.
As  the  tem peratu re gets   colder  it  may  be  necessary  to
direct  air  onto   the  wind shield . Adjust   the  tem peratu re
control  and   blow er speed   to  maintain   comfort.  Higher
blow er speed s  will  red uce fogging.   Interior  fogging   on
the  wind shield  can be  quickly  rem oved  by selecting  the
defrost  mode.
When  using the  air cond itioner  in extrem ely heavy  traffic
in  hot  weather   especially   when  tow ing  a  trailer,  addi-
tional  engine  cooling  may be  requ ired . If this situ ation is
encou ntered , operate  the  transm ission  in a  lower gear  to
increase  engine  RPM, coolant  flow  and  fan speed . When
stop ped in  heavy  traffic, it may  be necessary   to shift into
N  (Neutral)  and  depress   the  accelerator  slightly  for  fast
idle  operation  to  increase  coolant  flow  and  fan speed .
Regu lar  cleaning  of  the  insid e  of the   wind ows  with  a
non-film ing  cleaning  solu tion (vinegar   and  water  works
very   well)   will   help   prevent   contam inates   (cigarette
