Downloaded from www.Manualslib.com manuals search engine If your  vehicle  strikes something  that  will  move or 
deform,  such as a  parked  car, 
the threshold  level  will  be 
higher.  The  air  bag 
is not designed  to inflate in rollovers, 
side impacts  or rear  impacts,  because  inflation  would 
not  help  the occupant. 
In  any  particular  crash, no one can say  whether  an air 
bag  should  have  inflated  simply because 
of the damage 
to a vehicle  or because  of  what  the  repair  costs were. 
Inflation  is  determined  by  the angle of  the  impact  and 
the  vehicle’s  deceleration.  Vehicle damage 
is only one 
indication 
of this. 
The air  bag  system  is  designed  to work  properly  under  a 
wide  range 
of conditions, including  off-road  usage. 
Observe safe driving speeds, especially  on  rough  terrain. 
As always, wear your safety  belt. See “Off-Road 
Driving”  in  the Index  for more  tips 
on off-road  driving. 
What  makes  an  air  bag  inflate? 
In a  frontal  or near-frontal  impact  of  sufficient  severity, 
the air  bag  sensing  system detects that the vehicle is 
suddenly stopping as a  result of a  crash. The sensing 
system  triggers  a  chemical  reaction 
of the sodium azide 
sealed  in 
the inflator. The reaction  produces  nitrogen 
gas,  which  inflates 
the air  bag.  The inflator,  air  bag  and 
related  hardware are  all  part 
of the air bag  module 
packed  inside the steering  wheel. 
How does an  air  bag  restrain? 
In moderate  to severe frontal or near-frontal  collisions, 
even  belted  occupants can  contact  the  steering  wheel. 
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  air bags would 
not 
help  you  in  many  types of collisions,  including 
rollovers,  rear  impacts and side  impacts,  primarily 
because  an  occupant’s  motion 
is not toward  the  air bag. 
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.

There is  an air bag  readiness  light on the  instrument 
panel,  which  shows AIR 
BAG. The system  checks 
the  air bag’s  electrical  system for malfunctions.  The 
light  tells 
you if  there  is an  electrical  problem.  The 
system check  includes  the air bag sensors,  the  air 
bag 
module,  the  wiring  and  the diagnostic module.  For 
more  information  on the air bag system, see “Air  Bag” 
in  the  Index. 
AIR 
BAG 
You  will see this  light  flash 
for  a few  seconds  when  you 
turn  your  ignition  to RUN 
or  START.  Then 
the light 
should 
go out. This  means 
the  system  is  ready. 
If  the  air bag  readiness  light doesn’t  come 
on when you 
start  your  vehicle,  or stays  on, or comes on when  you 
are  driving,  your air bag  system  may  not  work  properly. 
Have  your  vehicle  serviced  right  away. 
Charging  System  Indicator  Light 
The charging  system  light 
will  come 
on briefly  when 
you  turn  on the  ignition, 
but  the  engine is not 
running,  as 
a check to 
show  you  it is  working. 
It  should  go out  once  the engine 
is running. If it stays 
on, or comes on while you are driving, you may  have a 
problem  with the charging  system. It could indicate  that 
you have  problems  with  a  generator drive belt, or 
another  electrical  problem.  Have 
it checked  right  away. 
Driving  while  this  light  is on could  drain  your  battery. 
If you  must  drive a  short  distance  with  the  light  on, be 
certain to turn off  all your accessories,  such  as the  radio 
and  air  conditioner.

~~ 
If  you keep  driving  your  vehicle  with  this  light 
on,  after  a  while,  your  emission  controls  may  not  work  as well,  your  fuel  economy  may  not  be  as 
good  and  your  engine  may  not  run  as smoothly. 
This  could  lead  to  costly  repairs  that  may  not  be 
covered  by  your  warranty. 
This  light  should  come on, as a check to show  you  it  is 
working,  when  the  ignition is  on  and  the  engine is  not 
running.  If the  light  doesn’t come on,  have 
it repaired. 
This light  will  also come 
on during a malfunction in one 
of  two  ways: 
Light  Flashing -- A misfire  condition  has  been 
detected.  A misfire  increases  vehicle  emissions  and 
may  damage  the emission control  system  on  your 
vehicle.  Dealer  or  qualified service  center  diagnosis 
and  service is required. 
Light  On  Steady -- An emission  control  system 
malfunction  has  been  detected on  your  vehicle. 
Dealer  or qualified service center  diagnosis  and 
service  may be  required. 
If  the  Light Is Flashing 
The following  may prevent  more  serious  damage to 
your  vehicle: 
Reduce  vehicle speed. 
0 Avoid  hard  accelerations. 
Avoid steep uphill  grades. 
0 If towing  a trailer,  reduce  the amount of cargo  being 
hauled  as  soon  as 
it is possible. 
If  the  light 
stops flashing  and  remains  on  steady,  see “If 
the  Light 
Is On Steady” following. 
If 
the light  continues  to flash, when  it  is  safe  to  do so, 
stop the vehicle. Put  your  vehicle  in  PARK (P). Turn  the 
key  off, wait  at  least 
10 seconds  and  restart  the  engine. 
If  the  light  remains  on steady,  see “If  the  Light 
Is On 
Steady” following.  If 
the light is still flashing  follow  the 
previous  steps, and drive  the  vehicle  to your  dealer or 
qualified  service center for service.

You may  be able to correct the emission system 
malfunction  by considering the following: 
Did  you just  put fuel into  your vehicle? 
If 
so, reinstall  the fuel  cap,  making sure to  fully install 
the cap.  The  diagnostic  system can determine  if the fuel 
cap  has  been  left  off  or improperly installed. This  will 
allow  fuel to evaporate into  the atmosphere. 
A few 
driving trips  should  turn  the  light  off. 
Did  you  just drive through  a deep  puddle  of water? 
If 
so, your  electrical  system  may  be  wet.  The condition 
will  usually  be  corrected when  the electrical  system 
dries  out.  A  few driving  trips should  turn 
the light off. 
Are  you  low on fuel? 
As your  engine starts to run out of fuel,  your  engine  may 
not 
run as  efficiently  as  designed  since small  amounts  of 
air  are  sucked  into the fuel line causing  a misfire. The 
system  can detect this. Adding fuel should correct this 
condition. Make sure 
to install  the fuel cap  properly.  It 
will  take  a few driving trips  to  turn  the light off.  Have 
you  recently  changed  brands  of fuel? 
If 
so, be  sure to fuel  your  vehicle with quality fuel (see 
“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 this condition, 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.

The upper  knob  regulates  the  temperature  of  the  air 
coming  through  the  system.  Turn  the  knob  clockwise  for  warmer 
air. Turn the  knob  counterclockwise  for  cooler  air. 
Mode Knob 
The  lower knob allows  you to choose  the direction  of 
air  delivery. 
OFF: This setting turns  the system  off. Some  outside air 
will  still enter  the  vehicle  whenever the  vehicle  is 
moving forward. 
MAX NC: This setting  provides  maximum  cooling 
with the least amount  of work. MAX A/C recirculates 
much 
of the air inside  your  vehicle so it cools  quickly. 
A/C: This setting cools  the air entering  your  vehicle  and 
directs  it  through  the  instrument panel outlets. 
+# BI-LEVEL A/C: Air is  delivered  through  the  heater 
floor  outlets 
as well as the  instrument  panel  outlets.

DEFROST: This setting directs  most air through 
the  windshield  defroster 
outlets and some through the 
heater outlets. 
Air  Conditioning  (Option) 
On  hot days, open the windows  long enough to  let  hot 
inside  air escape. This reduces  the  time 
it takes for your 
vehicle  to cool  down.  Then  keep  your  windows closed 
for  the  air  conditioner to  work  its  best. 
For  quick  cool-down 
on very  hot  days,  use MAX A/C 
with the  temperature  knob  turned  counterclockwise.  This 
setting  should  be  used  to  keep  odors  and/or  dust  from 
entering  the  vehicle.  For  normal  cooling  on  hot  days,  use 
A/C with the  temperature  knob  turned  counterclockwise. 
On 
cool but  sunny  days, use BI-LEVEL A/C to deliver 
warm  air to the floor  and cooler air  to  the  instrument 
panel  outlets. 
If  you  have  the  “VORTEC” 
4300 engine, when the  air 
conditioner  is  on,  you  may sometimes  notice  slight 
changes  in  your  vehicle’s  engine  speed  and  power.  This 
is normal  because  the  system is designed  to  cycle  the 
compressor  on  and 
off to  keep  the  desired  temperature.

Keep the  hood  and  front air  inlet  free of ice, snow  or 
any  other obstruction  (such  as leaves). The heater 
and  defroster  will  work  far better,  reducing the 
chance  of fogging  the inside  of your  windows. 
When  you  enter a vehicle  in cold  weather,  turn  the 
blower fan 
to HI for  a few  moments  before driving 
off. This  helps clear the intake ducts 
of snow and 
moisture,  and reduces the chance 
of fogging  the 
inside  of your  windows. 
Keep the air  path  under the front  seats clear  of 
objects. This  helps  air  to circulate throughout 
your  vehicle. 
Defogging  and  Defrosting 
On cool,  humid  days, use BLEND  to keep  the 
windshield  and  side windows  clear. 
Use  DEFROST to remove fog  or ice  from  the 
windshield  quickly  in  extremely humid or cold 
conditions.  Turn the temperature knob clockwise 
and  move  the fan  control  toward 
HI.

can  reach,  but  be  sure the vehicles  aren’t touching 
each  other. 
If they  are, it could  cause  a ground 
connection  you don’t  want.  You wouldn’t  be  able 
to 
start your  vehicle,  and  the  bad  grounding could 
damage  the electrical systems. 
You  could  be  injured 
if the vehicles  roll. Set the 
parking  brake  firmly  on  each  vehicle. Put  an 
automatic  transmission 
in PARK (P) or a manual 
transmission  in  NEUTRAL 
(N). If you  have a 
four-wheel-drive  vehicle  with a manual transfer  case 
shift  lever,  be  sure  the  transfer  case is  not 
in 
NEUTRAL (N). 
3. Turn  off  the  ignition on both vehicles. Unplug 
unnecessary  accessories plugged into the cigarette 
lighter,  or  accessory  power outlets, 
if you have  this 
option.  Turn  off  all  lamps  that aren’t  needed  as  well 
as radios.  This will avoid  sparks  and  help  save both 
batteries. 
In addition, it could  save your radio! 
NOTICE: 
If you leave  your  radio  on,  it  could  be  badly 
damaged.  The  repair  wouldn’t  be  covered by 
your  warranty. 
If your  vehicle  has  air  conditioning,  the  auxiliary 
electric  fan  under  the  hood can  start  up  even

If  you get the  overheat  warning  but  see or hear no 
steam,  the  problem  may  not  be too serious. Sometimes 
the engine  can  get  a little  too  hot  when  you: 
Climb  a long  hill on a hot  day. 
Stop  after  high-speed  driving. 
Idle for long  periods  in  traffic. 
Tow  a trailer.  See “Driving  on Grades” in the  Index 
If 
you get  the  overheat  warning with no  sign  of  steam, 
try  this  for  a minute  or 
so: 
1. If you have an air conditioner,  turn it off. 
2. Turn  on  your  heater  to full hot  at the highest  fan 
speed 
and open  the  window  as  necessary. 
3. If you’re in a  traffic  jam, shift to NEUTRAL (N); 
otherwise,  shift  to the highest gear while 
driving 
-- AUTOMATIC OVERDRIVE (,@) 
or  DRIVE (D) for  automatic  transmissions. 
If you  no  longer  have  the  overheat  warning, you can 
drive.  Just  to  be  safe, drive  slower  for  about 
10 minutes. 
If the  warning  doesn’t  come  back  on,  you  can 
drive  normally. 
If the  warning  continues, pull  over,  stop,  and  park  your 
vehicle  right  away. 
If there’s  still  no sign  of steam,  push  the  accelerator  until 
the engine  speed  is  about  twice 
as fast as normal  idle 
speed.  Bring  the  engine speed  back  to  normal  idle  speed 
after  two  or  three  minutes.  Now see 
if the  warning  stops. 
But then, if you still  have  the  .warning, turn ofthe 
engine 
and get everyone  out of the vehicle until  it 
cools down. 
You may decide  not  to lift  the  hood  but  to  get  service 
help  right 
away.
