Your air cleaner is located between the battery and 
coolant  recovery tank.  The 
air cleaner  assembly 
has  an indicator  that lets 
you  know  when  the  air 
filter  is  dirty  and  needs 
to  be  serviced. 
The  indicator is located  in the  air intake tube  between 
the  air cleaner and the engine.  See “Owner  Checks  and 
Services”  in the Index  on when  to check the  indicator. 
If 
the area inside the clear section  of the  indicator  is 
green,  no air  filter service.is required.  When  the area 
inside  the indicator is orange  and CHANGE  AIR 
FILTER  appears, the filter should  be replaced.

level 
is when the  engine oil  is changed. 
Change  both the fluid  and filter every 
50,000 miles 
(83 000 Ism) if the  vehicle  is  mainly  driven under one 
or,more  of these  conditions: 
0 In  heavy  city traffic  where  the outside temperature 
regularly reaches 
90” F (32 O C)  or higher. 
0 In hilly  or mountainous terrain. 
0 When  doing  frequent trailer towing. 
0 Uses such as found  in taxi, police or  delivery service. 
If  you  do not use your  vehicle under any of these 
conditions, the fluid  and filter  do not  require changing. 
See  “Scheduled  Maintenance Services”  in 
the Index.
