@ Section 7 Maintenance  Schedule 
IMPORTANT: 
KEEP  ENGINE OIL 
AT THE  PROPER 
.EVEL AND  CHANGE AS 
RECOMMENDED 
Introduction 
Your Vehicle and the  Environment 
Proper  vehicle  maintenance not only helps to keep your 
vehicle 
in good  working  condition. but also  helps the 
environment. 
All recommended  maintenance procedures 
are  important.  Improper  vehicle maintenance or  the 
relnoval  of important  components  can significantly 
affect the quality 
of the air we breathe.  Improper fluid 
levels or even  the wrong  tire inflation can increase the 
level 
of emissions  from your  vehicle. To help protect our 
environment,  and to help keep your vehicle 
in good 
condition,  please  lnaintain your vehicle properly.

How This Section  is  Organized 
The remainder  of this section is divided  into  five parts: 
“Part A: Scheduled  Maintenance Services” shows 
what to have  done and how  often.  Some  of these 
services  can be complex, 
so unless  you are technically 
qualified and have  the necessary  equipment,  you should 
let  your retailer’s  service department  or another 
qualified service  center do these  jobs. 
If you are skilled enough to do some  work on your 
vehicle, 
you will  probably  want to get the service 
information 
GM publishes.  See “Service Publications” 
in the Index. 
“Part B: Owner  Checks  and  Services” tells you what 
should  be checked whenever  you stop  for 
fuel. It also 
explains  what  you  can easily 
do to help keep your 
vehicle 
in good condition. 
“Part  C: Periodic Maintenance  Inspections” explains 
important inspections that your Aurora retailer’s service 
department or another qualified  service  center should 
perform. 
“Part D: Recommended  Fluids and Lubricants” lists 
some products 
GM recommends  to help keep your 
vehicle properly  maintained.  These products,  or their 
equivalents,  should  be  used whether  you do the work 
yourself  or have  it done. 
“Part E: Maintenance  Record” provides  a place  for 
you  to record the maintenance performed 
on your 
vehicle. Whenever  any maintenance 
is performed, be 
sure to write 
it down  in this part.  This will help you 
determine when your  next maintenance  should  be done. 
In  addition, 
it is a good  idea to keep  your maintenance 
receipts. They  may be needed 
to qualify your vehicle  for 
warranty repairs.

Part A: Scheduled  Maintenance 
Services 
Using  Your Maintenance  Schedule 
We at General  Motors want to help  you keep  your 
vehicle 
in good working  condition. But we don’t  know 
exactly how 
you’ll drive  it. You  may  drive  very 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  all the different ways people  use their GM 
vehicles,  maintenance  needs vary. 
You may even  need 
more  frequent  checks  and replacements  than you’ll find 
in the schedules  in this  section. So please read this 
section  and note  how  you  drive. 
If you have any 
questions on how  to  keep  your  vehicle 
in good 
condition,  see  your  Aurora retailer. 
This  part tells  you the maintenance  services  you should 
have  done  and when  you should  schedule  them.  If  you 
go  to your retailer  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. 
These  schedules  are  for  vehicles that: 
0 
0 
0 
carry passengers  and cargo within recommended 
limits.  You will find  these  limits  on your vehicle’s 
Tire-Loading  Information  label.  See “Loading  Your 
Vehicle” 
in the Index. 
are  driven 
on reasonable  road surfaces  within legal 
driving  limits. 
use  the recommended  unleaded  fuel.  See “Fuel” in 
the Index. 
Selecting  the  Right  Schedule 
First you’ll  need to decide which of the  two  schedules is 
right for your vehicle.  Here’s  how to  decide  which 
schedule 
to follow:

I Maintenance  Schedule I I 
The  services shown in this schedule up to 100,000 miles 
( 166 000 km)  should be performed  after  100,000 miles 
(1 66 000 km) at the  same  intervals. 
Footnotes 
f- 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 vehicle useful life.  We, however, urge  that 
all  recommended  maintenance  services be performed  at 
the indicated intervals and the maintenance be recorded. 
* Your vehicle has  an Engine Oil  Life Monitor. 
This  monitor  will show  you when  to  change  the oil 
-- 
usually between 3,000 miles (5 000 km) and 7,500 miles 
(1 2 500 km)  since  your last oil  change. Under severe 
conditions the indicator  may come 
on before 
3,000 miles (5 000 km). Never drive your vehicle 
more  than 
7,500 miles (12 500 km) or 12 months 
without  an oil change. 
The  system won’t detect dust  in 
the oil. So if  you 
drive 
in a dusty area  be sure  to  change  your oil every 
3,000 miles (5 000 km) or sooner  if the CHANGE OIL 
light  comes  on.  Remember  to reset  the Oil Life  Monitor 
when  the  oil  has  been  changed.  For more information, 
see  “Engine  Oil Life Monitor”  in the Index.
