What Makes  an Air Bag Inflate? 
In an impact  of sufficient severity,  the air bag  sensing 
system  detects that  the vehicle  is  in a crash.  For  both 
frontal and side impact air  bags,  the sensing system 
triggers  a release of  gas from  the inflator,  which inflates 
the  air bag.  The inflator, the  air bag and related  hardware 
are  all  part of the air  bag modules  inside the steering 
wheel,  the instrument panel, and the side  of the  front 
seatbacks  closest to  the door. 
How  Does  an Air Bag Restrain? 
In moderate  to  severe frontal or  near frontal collisions, 
even  belted  occupants  can  contact the steering  wheel 
or  the  instrument panel. In  moderate to  severe side 
collisions,  even belted  occupants  can contact  the inside 
of  the  vehicle.  The air bag  supplements  the protection 
provided  by safety belts.  Air  bags distribute  the force 
of  the  impact  more evenly over the occupant’s 
upper  body, stopping the  occupant  more gradually. 
But  the  frontal air  bags  would  not help you in many 
types  of collisions, including rollovers, rear impacts,  and 
many  side  impacts, primarily  because  an occupant’s 
motion  is not  toward  the air  bag. Side  impact  air bags 
would  not help  you 
in many types  of collisions, 
including frontal or  near frontal collisions, rollovers, and 
rear impacts, primarily  because  an occupant’s motion  is not toward those air 
bags.  Air  bags should never  be 
regarded as anything  more  than a supplement  to 
safety belts,  and then  only in moderate  to  severe  frontal 
or  near-frontal collisions for  the  driver’s  and  right front 
passenger’s frontal air  bags,  and  only in moderate 
to  severe side collisions  for  the driver’s  and  right  front 
passenger’s side impact air  bag. 
What  Will You See  After  an  Air  Bag 
Inflates? 
After  the air bag  inflates, it  quickly  deflates, so quickly 
that  some  people  may  not  even  realize the  air  bag 
inflated.  Some  components  of  the  air  bag  module  will be 
hot  for a short time.  These  components  include  the 
steering  wheel  hub  for  the  driver’s  frontal air  bag  and  the 
instrument panel  for  the  right front passenger’s  frontal 
air  bag.  For vehicles  with  side impact air  bags,  the  side 
of  the  seatback  closest to the  driver’s  and/or  right 
front passenger’s  door  will  be hot. The  parts  of the  bag 
that  come  into contact  with  you  may  be  warm,  but 
not  too  hot to touch.  There  will  be  some  smoke  and  dust 
coming  from the vents  in the  deflated  air  bags.  Air  bag 
inflation doesn’t prevent the  driver  from  seeing  or 
being able  to steer the  vehicle,  nor  does  it  stop  people 
from  leaving  the vehicle.

California Fuel 
If  your vehicle  is certified  to meet  California  Emission 
Standards  (see the underhood  emission control label), 
it is designed  to operate  on fuels  that meet  California 
specifications.  If this fuel  is not available  in states 
adopting California emissions standards, your vehicle 
will operate satisfactorily  on fuels meeting federal 
specifications, but emission control  system  performance 
may  be affected. The  malfunction indicator  lamp  may 
turn  on  (see 
Malfunction  Indicator  Lamp on page 3-47 ) 
and your vehicle  may fail a  smog-check  test. If this 
occurs,  return to your authorized  GM dealer  for 
diagnosis.  If it is  determined  that the condition is  caused 
by  the  type of fuel  used,  repairs  may not be covered 
by your warranty. 
Additives 
To provide cleaner air,  all gasolines in the United States 
are now required  to contain additives that will help 
prevent engine  and fuel system  deposits from forming, 
allowing  your emission control  system to work  properly. 
You  should  not  have  to add anything  to your  fuel.  Gasolines containing 
oxygenates,  such as ethers  and 
ethanol,  and reformulated  gasolines  may  be available  in 
your area to contribute  to clean air.  General  Motors 
recommends  that you  use  these  gasolines,  particularly 
if they  comply  with the specifications  described  earlier. 
Notice: Your  vehicle  was  not  designed  for  fuel 
that  contains  methanol.  Don’t  use  fuel  containing 
methanol. 
It can  corrode  metal  parts in  your  fuel 
system  and  also damage  the  plastic  and  rubber 
parts.  That  damage wouldn’t  be covered  under 
your  warranty. 
Some  gasolines that  are not reformulated  for  low 
emissions  may contain  an  octane-enhancing  additive 
called methylcyclopentadienyl  manganese  tricarbonyl 
(MMT);  ask  the attendant  where  you  buy  gasoline 
whether  the fuel contains  MMT.  General  Motors  does 
not  recommend  the use  of  such  gasolines.  Fuels 
containing  MMT can reduce  the  life of  spark  plugs  and 
the  performance  of the  emission control  system  may 
be  affected.  The  malfunction indicator  lamp  may  turn on. 
If this occurs, return  to  your authorized GM dealer 
for  service.

When  you put the  fuel  cap  back  on,  turn it to the  right 
(clockwise)  until you  hear  a  clicking sound.  Make 
sure  you  fully install  the cap.  The diagnostic  system  can 
determine 
if the fuel  cap  has  been  left off or improperly 
installed.  This would  allow  fuel to evaporate into  the 
atmosphere.  See 
Malfunction Indicator  Lamp on 
page 3-47. 
The  malfunction indicator lamp  (SERVICE  ENGINE 
SOON  or  CHECK  ENGINE  light) will come  on 
if the 
fuel  cap  is not  properly installed. 
Notice:  If you  need  a  new  fuel  cap, be  sure  to get 
the  right  type.  Your  dealer  can  get  one  for  you. 
If you  get  the  wrong  type, it may  not  fit  properly. 
This  may cause  your  malfunction  indicator  lamp  to 
light  and  may  damage  your  fuel  tank  and  emissions 
system.  See “Malfunction  Indicator  Lamp” 
in the 
Index. 
Filling a Po -able Fuel C ‘ainer 
I- 
I fil  portablc  uel  container  while it is in

the  container  can  ignite  the  gasoline  vapor. 
You  can  be  badly  burned  and  your  vehicle 
damaged  if  this  occurs. 
To help  avoid  injury 
to  you  and  others: 
Dispense  gasoline  only  into  approved 
containers. 
Do not  fill  a  container  while it is inside a 
vehicle,  in  a  vehicle’s  trunk,  pickup  bed  or  on  any  surface  other  than  the  ground. 
Bring  the  fill  nozzle  in  contact  with  the 
inside  of  the  fill  opening  before  operating 
the  nozzle.  Contact  should  be  maintained 
until the  filling is complete.
