Change  Oil Soon Light 
Your CHANGE  OIL  SOON 
light should come on as  a 
CHANGE OIL 
SOON 
bulb check when  you start 
the  engine. 
Security  Light 
SECURITY 
This  light  will come on 
when  you turn the  key 
to 
START and stay on until the 
vehicle  starts. 
If  this  light  stays  on for  about 
20 seconds  after you  turn 
on the  ignition,  have the oil changed. 
When to change your oil  also depends on  driving habits 
and  conditions  because 
they directly affect  engine speed, 
coolant  temperature  and vehicle  speed.  Because of this, 
the  CHANGE  OIL 
SOON light  may come  on as early as 
2,000 miles (3,200 km) or  less  for  harsh conditions. 
Also  see “Maintenance Schedule”  in the Index  for 
further  instructions  on when 
to change your  oil. 
To reset the  CHANGE  OIL  SOON  light,  see “CHANGE 
OIL SOON Light,  How to Reset”  in the  Index.  Also,  see 
“Oil  Life Monitor” 
in the  Index.  It 
will  also  flash  if your  ignition  key is  too  dirty or wet 
for  the  PASS-Key  I1 system to read the resistor pellet. 
See  “Pass-Key 
11” in the  Index. 
If  the resistor pellet  is damaged  or missing, the light will 
come 
on. 
If  you’re  ever  driving  and the SECURITY light comes 
on,  you  will  be able to restart your  engine 
if you turn it 
off.  Your  PASS-Key  I1 system, however,  is not working 
properly and must  be serviced  by your dealer.  Your 
vehicle  is not protected  by the PASS-Key  I1 system.

Modes 
AVG ECON: Shows your  average fuel economy  since 
you  last reset this mode. Average  fuel economy  is 
viewed  as a long term approximation  of your overall 
driving  and driving  conditions.  To learn the  average fuel 
economy  from a new  starting  point, press  the RESET 
button while 
the average  fuel  economy is displayed  in 
the 
DIC. 
INSTANTANEOUS  FUEL  ECONOMY Shows your 
current  fuel  economy. Instantaneous fuel economy 
varies  with your  driving  conditions,  such as 
acceleration, braking and the  grade of the road being 
traveled.  The instantaneous  fuel economy display cannot 
be  reset, therefore the reset button has no effect while  in 
this mode. 
OIL  LIFE  MONITOR: Shows  an estimate of the oil’s 
remaining useful life.  When 
the oil  life index is less than 
lo%, the CHANGE OIL SOON light will come  on. 
When  you have the oil changed according to the 
maintenance schedule  (see “Maintenance Schedule” in 
the  Index),  you will have  to reset the oil  life monitor. 
To 
do this,  press and hold the  RESET button for more than 
five  seconds while the oil  life monitor is being displayed 
on the DIC.  The oil life will change 
to 100%. 
RANGE: Shows the approximate  distance you can 
drive  without refueling.  This 
is based on the amount of 
fuel  in the tank and on the fuel economy  of the most 
recent 
25 miles (40 km). Pressing RESET while in this 
mode will have no effect. 
BOOST GAGE: If you have the supercharged  engine, 
this gage will show 
the amount  of boost your  engine is 
receiving. Pressing RESET while  in this mode will have 
no effect.

As shown in the  chart, SAE 1OW-30 is best  for your 
vehicle. However,  you can 
use SAE 5W-30 if  it’s going 
to  be  colder  than 
60°F (1 6 O C) before your next oil 
change. When  it’s  very cold, 
you should use SAE 
5W-30.  These numbers  on an oil  container show  its 
viscosity,  or thickness. 
Do not  use other  viscosity oils, 
such 
as SAE 20W-50. 
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 where  the temperature falls below 
-20°F 
(-29”C), consider  using 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.  Your dealer  is ready to 
advise  if  you think something should  be added. 
When to Change  Engine Oil 
Your  vehicle has an  Oil  Life Monitor.  This  feature 
will  let you  know when to change your oil  and 
filter 
-- 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 
(whichever occurs first) 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. Remember to reset 
the CHANGE  OIL 
SOON light when the oil has been 
changed.  For more information,  see “Change Oil Soon 
Light”  in the Index. 
How to  Reset  the CHANGE OIL SOON Light 
After changing the  engine oil, the system must be reset. 
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, 
6-16 
ProCarManuals.com 

then  start  the  vehicle. If the CHANGE OIL  SOON light 
comes back on, the system has not  reset. Repeat the 
procedure. 
(If you have a  driver  information  center, the 
system  may be reset  by depressing  the DIC 
RESET 
button for  five  seconds while viewing  the oil life  display 
on the DIC.  See “Driver  Information  Center”  in 
the  Index.) 
What  to Do with Used Oil 
Did  you know that 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 throw 
away  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 real  threat  to  the  environment. 
If you 
change your own  oil, be sure  to drain  all  free-flowing  oil 
from  the filter  before  disposal.  Don’t ever  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. 
Air Cleaner 
To check  or  replace  the air 
filter, loosen  the wing nut 
on  the  air  duct  and lift 
up on 
the two clips  located  on the 
top  of the  filter  cover. 
Disconnect the  duct and 
reposition 
it while removing 
the  side  cover. 
Pull  out  the filter.  Be  sure 
to install the air  filter and 
install  the cover tightly when  you are finished. 
Refer 
to the Maintenance  Schedule to  determine when to 
replace  the  air  filter. 
See  “Scheduled Maintenance  Services’’  in the Index.
