Footnotes 
t The U.S. Environmental Protection  Agency  or the 
California  Air  Resources  Board  has  determined  that the 
failure  to perform  this  maintenance  item  will not nullify 
the  emission  warranty or limit recall liability prior  to 
the  completion  of  the  vehicle’s useful life. We, however, 
urge  that  all recommended  maintenance  services be 
performed  at the  indicated intervals and  the 
maintenance  be  recorded. 
+A good  time  to  check  your  brakes is during tire 
rotation.  See  Brake  System  Inspection on  page

Engine Oil Scheduled Maintenance 
Change engine  oil and  filter as indicated by the GM 
Oil Life SystemTM (or every 12 months, whichever 
occurs  first).  Reset  the system. 
Your  vehicle  has  a  computer  system  that  lets you know 
when  to change  the engine oil and filter.  This is 
based  on  engine revolutions and engine temperature, 
and  not  on  mileage. Based on driving conditions, 
the  mileage  at  which  an  oil change  will be indicated  can 
vary considerably.  For the oil life  system to work 
properly,  you  must  reset the system  every time the oil  is 
changed. 
When  the system  has  calculated that oil  life  has been 
diminished, 
it will indicate that  an  oil  change is 
necessary. 
A CHANGE OIL SOON light will come  on. 
Change  your oil as soon  as possible within the  next  two 
times  you  stop  for  fuel.  It is possible that, 
if you are 
driving  under  the  best conditions, the oil  life  system  may 
not indicate that  an oil change  is necessary  for  over a 
year.  However,  your  engine oil and filter  must  be 
changed  at  least once  a  year and  at  this time the  system 
must  be  reset. 
It is also important to  check your oil 
regularly  and  keep  it at  the  proper level.
