As in the  chart  shown  previously, SAE 5W-30 is the 
only  viscosity  grade  recommended  for  your  vehicle. 
You  should  look  for  and  use only oils  which  have the 
API  Starburst  symbol  and which  are  also identified 
as  SAE  5W-30.  If  you  cannot find such SAE 5W-30  oils, 
you  can  use  an  SAE  IOW-30 oil which  has the  API 
Starburst  symbol, 
if it's  going to  be 0°F (-18°C) 
or  above.  Do  not  use  other  viscosity grade  oils,  such as 
SAE  1OW-40  or  SAE  20W-50 under any  conditions. 
Notice: Use  only  engine oil  with  the American 
Petroleum  Institute  Certified  For  Gasoline Engines 
starburst  symbol.  Failure  to  use the recommended 
oil  can  result  in  engine  damage not covered  by 
your  warranty. 
GM  Goodwrench@  oil meets all the requirements  for 
your  vehicle. 
If  you  are  in an  area  of extreme cold,  where the 
temperature  falls  below  -20°F 
(-29"C), it is 
recommended  that  you  use either  an SAE  5W-30 
synthetic  oil  or  an  SAE  OW-30 oil. Both will  provide 
easier  cold starting  and  better protection  for  your engine 
at  extremely 
low temperatures. 
Engine  Oil  Additives 
Don't  add  anything  to your  oil.  The recommended  oils 
with  the starburst  symbol  are all you will need  for 
good  performance  and  engine protection. 
When to  Change Engine Oil 
(GM Oil Life SystemTM) 
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  ENGINE 
OIL SOON message 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. 
If the system is ever  reset  accidentally,  you  must 
change  your oil at  3,000  miles (5 
000 km) since your 
last oil  change.  Remember  to reset  the  oil life system 
whenever  the oil is changed.

Part A: Scheduled  Maintenance 
Services 
This part contains engine oil and chassis lubrication  scheduled  maintenance  which  explains the engine oil life 
system  and  how  it indicates  when to change  the 
engine oil  and filter.  Lubricate chassis  components with 
each  oil change. 
Also, listed are  scheduled  maintenance 
services  which are to be  performed  at the  mileage 
intervals specified. 
Using  Your Maintenance  Schedule 
We  at General Motors  want to help  you  keep  your 
vehicle in  good 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 in 
very  hot,  dusty weather.  You  may  use  your vehicle in 
making  deliveries.  Or  yo  may  drive 
it to work,  to 
do  errands  or in many  other ways. 
Because 
of all the different  ways people  use their 
vehicles,  maintenance  needs  vary.  You  may  need  more 
frequent  checks  and  replacements. 
So please read 
the  following  and note  how  you  drive. 
If you  have  any 
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 
so 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 
limits.  You  will  find these limits  on  your  vehicle’s 
Certification/Tire  label.  See 
Loading Your Vehicle  on 
page  4-45.

Scheduled  Maintenance 
The  services  shown in this schedule up to 100,000 miles 
(1 66 000 km)  should  be repeated after 100,000 miles 
(1 66 000 km)  at the same  intervals  for the life  of 
this  vehicle.  The  services shown at 
150,000 miles 
(240 
000 km)  and  200,000  miles (332 000 km) should 
be  repeated  at  the  same  intervals after 150,000 miles 
(240 
000 km)  and  200,000  miles (332 000 km) for the life 
of  this  vehicle. 
See 
Part  B:  Owner  Checks  and  Services on page 6-10 
and Part C: Periodic  Maintenance  Inspections on 
page 
6- 14. 
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 
6-15. 
Engine Oil and Chassis Lubrication 
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  ENGINE OIL message will 
come  on. Change  your oil as  soon as possible within 
the  next  two times  you stop  for fuel.  It is possible that, 
it 
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.
