“Fuel” 
in the  Index).  Poor  fuel  quality  will  cause  your 
engine  not  to  run  as  efficiently  as  designed. 
You may 
notice  this  as  stalling  after  start-up,  stalling  when  you 
put  the  vehicle  into  gear,  misfiring,  hesitation  on  acceleration  or  stumbling  on  acceleration.  (These 
conditions  may  go  away  once  the  engine  is warmed  up.) 
This  will  be  detected  by  the system  and  cause  the  light 
to  turn  on. 
If  you  experience  one  or  more  of these  conditions, 
change  the  fuel  brand  you  use.  It  will  require  at  least  one 
full  tank 
of the  proper  fuel to  turn  the  light off. 
If none  of the  above  steps  have  made  the  light  turn off, 
have  your  dealer  or  qualified  service  center  check  the 
vehicle. 
Your dealer  has  the  proper  test  equipment  and 
diagnostic  tools  to  fix  any  mechanical 
or electrical 
problems  that  may  have  developed. 
Oil Pressure Light 
This  light  tells  you if there 
could  be  a  problem  with 
your  engine  oil  pressure. 
The  light  goes  on  when  you  turn  your  key  to 
ON or 
START.  It  goes 
off once  you  start  your  engine.  That’s a 
check  to  be  sure  the  light  works.  If  it doesn’t  come  on, 
be  sure  to  have  it fixed 
so it will be  there  to warn you if 
something  goes  wrong. 
When  the  light 
comes on  and stuys on, it  means 
that  oil isn’t  flowing  through  your  engine  properly. 
You 
could  be  low  on  oil  and  you  might  have  some  other 
system  problem.

Driver  Information  Center  Messages 
These  messages  will  appear  if  there  is  a  problem  sensed 
in  one  of your  vehicle’s  systems.  Vehicles  that 
are first 
sold  in Canada  will  have  a  number  after  each  message. 
This  number  helps  to  identify  the  message  which  is  only 
displayed  in English. 
BATTERY  NOT  CHARGING - 7: This  message  will 
appear  if  the  battery  is  not  being  charged.  Have  the 
electrical  system  checked  by  your  dealership  at  your 
earliest  convenience. 
BATTERY  SAVER  ACTIVE - 27: This  message is 
displayed  when  the  vehicle  has  detected  that  the  battery 
voltage  is  dropping  beyond  a  reasonable  point.  The 
battery  saver  system  will  start reducing  certain  features 
of  the  vehicle  that  you  may  not  be  able  to notice.  At  the 
point  that  features  are  disabled,  this  message  is  displayed.  It is  used  to  convey  that  the vehicle  is trying 
to  save  the  charge  in  the  battery.  Turn 
off unnecessary 
accessories  to  allow  the  battery  to  recharge.

appear  when  the  electrical  system  is charging  less  than 
9 volts  or  if the  battery  has  been  drained.  If  this  message 
appears  immediately  after  starting,  it 
is possible  that  the 
generator  can  still  recharge  the  battery.  The  battery  should  recharge  while  driving  but  may  take  a  few  hours 
to  do 
so. Consider  using  an  auxiliary  charger  (be sure  to 
follow  the  manufacturer’s  instructions)  to  boost  the 
battery  after  returning  home  or  to a  final  destination.  If 
this  message  appears  while  driving  or after  starting  your

it is  time  to  replace  the  transaxle  fluid.  See 
the  Maintenance  Schedule  booklet  for  the  proper  fluid  and  change  intervals. 
CHECK  BRAKE  FLUID - 37: This  message  will 
display  if  the  ignition  is in 
ON to inform  the  driver  that 
the  brake  fluid  level  is low.  Have  the  brake  system 
serviced  by a  technician  as  soon  as  possible.  See  “Brake 
System  Warning  Light”  in  the  Index. 
CHECK  COOLANT  LEVEL - 2: This  message  will 
appear  when  there  is a  low  level  of engine  coolant.  Have 
the  cooling  system  serviced  by a  technician  as  soon 
as  possible. 
CHANGE  ENGINE  OIL - 82: This  means  that  the  life 
of  the  engine  oil  has  expired  and  it  should  be  changed 
within 
200 miles.  See “Engine  Oil”  and  “Filter 
Recommendations”  in  the  Maintenance  Schedule

Downloaded from www.Manualslib.com manuals search engine Oil Life Indicator 
This feature lets  you know when to change  the  engine 
oil.  It's  based  on  the  engine  oil temperatures  and  your 
driving  patterns.  To see the  display,  press  the  INFO 
button  several  times  until  ENGINE  OIL LIFE  appears. 
If you see 99% ENGINE OIL LIFE, 99 percent  of your 
current  oil  life remains. 
The DIC  may  display  a  CHANGE  ENGINE OIL 
message.  Always  keep  a  written  record of the mileage 
and  date  when 
you changed  your  oil.  For more 
information,  see the Maintenance  Schedule  booklet.  If 
you  see CHANGE  ENGINE  OIL, it means  the oil  life 
is 
gone  and you should  change  the oil right  away.  The 
system  doesn't  check 
how much oil you  have, so you'll 
still  have  to  check  for that. 
To see  how,  see  "Engine  Oil" 
in  the  Index.  The 
system  should  indicate  changing  the  oil  between 
3,000 miles (5 000 km) and 7,500 miles (12 500 km). 
It may  indicate  changing  the  oil  before 3,000 miles 
(5 000 km) depending  on  your  driving  habits.  If the 
vehicle  has  been  driven 
7,500 miles (12 500 km),  it  will 
indicate  to  change  the oil. If you  drive 
in a  dusty  area, 
you  should  change  your  oil  every 
3,000 miles 
(5 000 km) or  three  months  (whichever  comes  first) 
unless  the display  indicates  changing  it sooner. 
When  the  oil is  changed,  you'll need  to  reset  the  system. 
To reset,  display  the  Oil  Life  Indicator  by pressing  the 
INFO  button.  Then  press  and  hold  the  INFO  RESET 
button  until  the  display  shows

Overheated  Engine  Protection 
Operating  Mode 
NOTICE: 
After driving  in the overheated  engine  protection 
operating  mode, to avoid  engine  damage,  allow 
the  engine  to cool  before  attempting any  repair. 
The  engine  oil  will  be  severely  degraded. Repair 
the  cause 
of coolant  loss,  change  the oil and  reset 
the  Oil  Life  Indicator.  See  “Engine  Oil,  When  to 
Change”  in  the Index. 
Should an overheated  engine condition  exist and  the 
message  ENGINE 
OVERHEATED STOP  ENGINE  is 
displayed,  an overheat  protection  mode  which  alternates 
firing  groups 
of four  cylinders  helps  prevent  engine 
damage.  In  this  mode,  you  will  notice 
a loss  in  power 
and  engine  performance.  This operating  mode  allows 
your  vehicle  to  be  driven  to 
a safe place  in an 
emergency;  you  may  drive up 
to 50 miles (SO km). 
Towing  a  trailer  in 
the overheat  protection  mode  should 
be  avoided.

Downloaded from www.Manualslib.com manuals search engine What Kind of Engine  Oil to Use 
Oils  recommended for your  vehicle  can be  identified  by 
looking  for the  "Starburst"  symbol.  This symbol 
indicates  that  the  oil has  been  certified  by  the American 
Petroleum  Institute 
(API). Do not  use  any  oil which 
does  not  carry  this  Starburst  symbol. 
If you  change  your  own 
oil,  be  sure  you  use  oil 
that  has  the Starburst 
symbol  on  the front 
of the 
oil  container.  If  you  have 
your  oil  changed  for you, 
be  sure  the oil put  into 
your  engine  is American 
Petroleum  Institute  certified 
for gasoline  engines. 
You should  also  use  the proper  viscosity  oil  for your 
vehicle,  as shown  in  the following  chart:

Downloaded from www.Manualslib.com manuals search engine 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 OF ( 16 “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  Indicator.  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  Oil  Life  Indicator  when  the  oil has  been  changed. 
For  more  information,  see “Oil  Life  Indicator”  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.
