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  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. 
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. 
How to  Reset the GM Oil Life System 
The  GM Oil Life  SystemTM  calculates  when to change 
your  engine  oil and filter  based  on  vehicle  use.  Anytime 
your  oil is  changed,  reset  the system 
so it can  calculate 
when  the next  oil change is  required. 
If a situation occurs 
where  you change  your  oil prior to a CHANGE 
OIL SOON 
light  being turned  on,  reset the system. 
To  reset  the GM  Oil Life  SystemTM  after the oil has 
been  changed,  use  one of the  following  two procedures: 
Using the  Driver  Information  Center  (DIC) 
1. 
2. 
3. 
With the  ignition  key in RUN  but  the  engine off, fully 
push  and release  the  accelerator  pedal slowly three 
times  within  five  seconds. 
If the  CHANGE  OIL SOON light flashes, the  system 
is  resetting. 
Turn  the  key  to OFF  after  the  light stops  flashing, 
then  start  the  vehicle. 
If the CHANGE OIL SOON light comes  back on, the 
engine  oil  life monitor  has  not  reset.  Repeat the 
procedure. 
Using  the Trip Computer  (If  Equipped) 
1. Press the MODE button until  the  light appears  lit 
2. Press and hold the RESET  button for three  seconds. 
next to 
OIL LIFE. 
The 
oil life  percentage  should change to 100%.

What to Do with Used Oil 
Used engine oil contains certain  elements that may  be 
unhealthy  for your skin  and could  even  cause  cancer. 
Don't  let  used oil stay  on your skin for very  long.  Clean 
your  skin and nails with  soap  and water, or a  good 
hand cleaner.  Wash or  properly dispose  of clothing  or 
rags containing  used engine oil.  See the  manufacturer's 
warnings  about the  use  and  disposal of oil products. 
Used  oil can  be  a threat to the environment.  If  you 
change your  own oil, be sure  to drain  all the oil from the 
filter  before disposal.  Never dispose  of oil  by  putting it 
in the  trash, pouring  it on  the ground, into sewers, or into 
streams  or  bodies of water.  Instead, recycle  it by 
taking 
it to  a place that collects  used oil. If you  have  a 
problem  properly disposing  of your  used  oil, ask 
your  dealer, a service station  or  a local recycling 
center for  help. 
Supercharger Oil 
Unless you are technically 
qualified  and  have  the 
proper tools,  you should  let 
your  dealer  or  a qualified 
service  center  perform 
this  maintenance. 
When  to Check 
Check  oil level every 30,000 miles (50 000 km)  or  every 
36 months,  whichever  occurs  first. 
What Kind of Oil to Use 
Use only  the recommended  supercharger  oil.  See Part 
D: Recommended  Fluids and Lubricants on page 6-15. 
5-24  

How to Check and Add Oil 
Park  the vehicle on  a level surface.  Check oil only  when 
the  engine  is cold. Allow the engine  to cool  two to 
three  hours  after running. 
I 
If you  remove  the supercharger oil fill plug 
while  the engine 
is hot, pressure  may  cause 
hot  oil to  blow  out  of the oil fill  hole.  You  may 
be burned. Do not  remove  the  plug until the 
engine 
cools. 
1. Clean  the area  around the oil fill plug before 
removing  it. 
2.  Remove  the  oil 
fill plug. 
3. The  oil  level is correct  when it just  reaches the 
bottom  of the  threads  of the  inspection hole. 
4. Replace  the  oil plug  with  the O-ring  in place. 
Tighten to 
88 Ib-in (10 Nom ). 
Engine Air Cleaner/Filter 
The  engine air cleanedfilter is located  in  the engine 
compartment  on  the driver’s side  of the  vehicle. 
See Engine Compartment Oven/iew on page 5-12 for 
more  information  on location. 
To check  or  replace the engine air cleanedfilter do  the 
following: 
1. Loosen  the  two  clips on the top  of the  engine  air 
cleaner/filter housing and lift  the filter cover  tabs 
out  of the housing. 
2.  Push  the filter cover housing toward  the engine.

Automatic  Transaxle  Fluid 
When to Check and Change 
A good time to  check  your  automatic transaxle fluid 
level is  when  the  engine  oil is changed. 
Change  both the fluid  and filter  every  50,000 miles 
(83 
000 km) if the  vehicle  is mainly driven  under  one  or 
more  of these  conditions: 
In heavy  city traffic  where  the  outside temperature 
0 In hilly or  mountainous  terrain. 
0 When doing frequent  trailer towing. 
0 Uses  such  as found  in taxi, police  or delivery service. 
regularly  reaches 
90°F (32°C) 
or higher. 
If  you  do  not  use  your  vehicle under  any  of these 
conditions,  change  the  fluid and filter at 
100,000 miles (166 000 km). 
See  Part 
A: Scheduled  Maintenance  Services on 
page 
6-4. 
How to Cheek 
Because  this operation  can be  a  little difficult,  you may 
choose  to have  this done  at the  dealership service 
department. 
If  you  do  it yourself,  be sure  to follow  all  the  instructions 
here,  or  you  could get a false  reading  on the  dipstick. 
Nofice: Too much  or too  little  fluid  can damage 
your  transaxle. 
Too much  can  mean  that  some of the 
fluid  could  come  out and  fall on  hot  engine  or 
exhaust system parts,  starting  a  fire. 
Too little fluid 
could  cause  the transaxle  to  overheat. Be  sure 
to  get  an accurate  reading 
if you  check  your 
transaxle  fluid. 
Wait  at  least 30 minutes before checking  the transaxle 
fluid  level 
if you  have  been  driving: 
When  outside temperatures are  above 
90°F (32°C). 
At  high  speed  for  quite a  while. 
In  heavy  traffic 
- especially  in hot  weather. 
While pulling  a trailer.
