Using Your  Maintenance  Schedule 
We at  General Motors  want to keep  your vehicle  in good 
working condition. But  we  don’t  know exactly how 
you’ll drive  it.  You  may  drive short distances only  a  few 
times  a  week.  Or  you  may  drive long distances  all 
the  time  in  very hot, dusty weather.  You  may  use  your 
vehicle 
in making  deliveries.  Or  you  may  drive it to 
work,  to do errands or  in many  other ways. 
Because  of the different  ways people  use their vehicles, 
maintenance  needs  may  vary. You  may  need  more 
frequent  checks  and  replacements. 
So please read the 
following  and note  how  you  drive. 
If you  have 
questions  on  how to keep  your vehicle  in good  condition, 
see  your  dealer.  This part tells 
you the maintenance  services you 
should  have  done  and  when  you  should schedule  them. 
When  you  go to your  dealer  for  your  service  needs, 
you’ll  know that GM-trained  and supported  service 
people will perform the  work using  genuine  GM  parts. 
The  proper fluids and lubricants to  use are listed  in 
Part  D. Make  sure whoever  services your  vehicle  uses 
these. 
All parts should  be replaced  and  all  necessary 
repairs  done before  you  or  anyone  else drives  the 
vehicle. 
This schedule  is for  vehicles  that: 
carry  passengers  and  cargo  within recommended
