Explanation of Scheduled 
Maintenance  Services 
Following  are explanations  of the services 
listed  in  Schedule  I  and Schedule 
11. 
The proper  fluids and lubricants to  use are 
listed  in  Section  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.

displacement  and  code, see 
“Engine Identification”  in  the

1 Engine  Oil  and  Filter Change* - 
Always  use SH or SG Energy 
Conserving  I1 oils  of proper 
viscosity.  The engine requires  a 
special  oil meeting  GM  Standard 
GM4718M.  Oils meeting  this 
Standard  may  be  identified  as 
synthetic,  and  should  also be 
identified  as API Service 
SH or 
SG.  However,  not  all Synthetic 
API  Service 
SH oils  will  meet

this GM  Standard. You should 
look  for and use only an oil  that 
meets  GM  Standard  GM4718M. 
To  determine the  preferred 
viscosity  for your  vehicle’s 
engine  (e.g., 
SAE 5W-30  or SAE 
10W-30),  see “Engine  Oil” in 
the  Index. 
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 
( 12 500 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.

Now  and  then,  make  sure all your  belts,  buckles,  latch  plates,  retractots,  anchorages  and 
reminder  systems are  working  properly. 
Look for any  loose  parts  or  damage.  If you  see  anything 
that  might  keep  a restraint  system  from doing  its  job, have 
it repaired. 
Inspect  the  front  and  rear  suspension  and  steering systenl for damaged,  loose  or  missing  parts, 
signs  of wear,  or  lack 
of lubrication.  Inspect  the  power  steering  lines  and  hoses  for  proper 
hookup,  binding,  leaks, cracks, chafing, etc. 
Inspect  the  tires  for uneven  wear  or damage.  If there  is irregular  or premature  wear,  check 
the 
wheel  alignment.  Inspect  for  damaged  wheels. 
Inspect  the  complete  exhaust  system.  Inspect  the  body  near  the \
 exhaust  system. 
Look for  broken, 
damaged,  missing  or  out-of-position  parts  as  well as open  seams,  holes,  loose  connections,  or 
other  conditions  which  could  cause a heat  build-up  in 
the floor pan  or  could  let  exhaust  fumes 
into  the  vehicle.  See “Engine Exhaust” 
in the Index.
