The front axle  portion  of the  diagram  on  the indicator  will  light  up  when 
you  shift  into  four-wheel  drive.  A  slight  delay  between  shifting  an\
d  the 
pattern’s  lighting  is  normal.  If  the  pattern  does  not light  up, or if  the  front 
axle  does  not  go  out  after  you  shift  out  of  four-wheel drive,  have  your 
dealer  check  your  system.  Turn  the 
INT  LIGHTS switch  located  to  the 
right  of your  headlight  switch  to  dim  your  transfer  case  indicator  light\
  when 
your  headlights  or  parking  lights  are  on.  This  will  also  cause\
  your 
instrument  panel  lights  to  dim. 
2HI: This  setting  is  for driving  in  most  street  and  highway  situations.  Your 
front axle  is  not  engaged  in  two-wheel  drive. 
4HI: This  setting  engages  your  front  axle  to  help  drive  your  vehicl\
e.  Use 
4HI when  you  need  extra  traction,  such  as  on  snowy  or  icy  roads, \
 or  in  most 
off-road  situations. 
N SET  PARK  BRAKE:  Shift to  this  neutral  setting  only  when  your  vehicle 
needs  to  be  towed. 
4LO: This  setting  also  engages  your  front  axle  to  give  you  extra  traction. 
You  may  never  need 
4LO. It sends  the  maximum  power  to  all  four  wheels. 
You  might  choose 
4LO if  you  were  driving  off-road in sand,  mud,  or  deep 
snow  and  climbing  or  descending  steep  hills. 
You  can  shift  from 
2HI to 4HI or  from 4HI to 2HI while  the  vehicle  is 
moving.  It is not  necessary  for  you  to  press  the  transfer  case  shift  lever 
button.  Your front  axle  will  engage  faster 
if you  take  your  foot off of the 
accelerator  for a  few  seconds  after  you  shift. 
To shift  your  transfer  case  into N SET  PARK  BRAKE: 
1. Stop  the  vehicle  and  shift  your  transmission  into “N” (Neutral). 
2. Set the  parking  brake.  Your vehicle  can  roll  unless  the  brakes  are 
applied. 
To shift  into  or  out  of 4LO : 
1. The vehicle  must  be  stopped  or  moving  less  than 3 mph (4.8 Wh) 
with  the  transmission  in “N’ (Neutral) or the  clutch  pedal  depressed. 
2. Press  the  transfer  case  shift  button  and  shift  in one continuous  motion. 
Don’t  pause  in 
N SET  PARK  BRAKE  as  you  shift into or  out  of 4L0, or 
your  gears  could  clash. 
Remember  that  driving  in 
4HI or 4LO may  reduce fuel economy.  Also, 
driving  in  four-wheel  drive  on  dry  pavement  could  cause  your  t\
ires  to  wear 
faster  and  make  your  transfer  case  harder  to  shift.

instrument  panel  will 
flash  in  the  direction 
of  the  turn 
or lane 
change. 
To  signal  a  lane  change,  just raise  or  lower  the  lever  until  the  green  arrow 
starts  to flash.  Hold it there  until  you  complete  your  lane  change.  The lever 
will  return  by  itself  when  you  release  it. 
As you  signal  a  turn  or  a  lane  change,  if  the  arrows  don’t  f\
lash  but  just stay 
on,  a  signal  bulb  may  be burned  out  and  other  drivers  won’t  see  your  turn 
signal. 
If  a  bulb  is burned  out,  replace  it  to  help  avoid  an  accident.  If the  green 
arrows  don’t  go 
on at  all  when  you  signal a turn,  check  the  fuse  (see  “Fuses” 
in  the  Index)  and  for burned-out  bulbs. 
If  you  have  a  trailer  towing  option  with  added  wiring  for 
the trailer  lights, a 
different  turn  signal  flasher is used.  With  this  flasher  installed,  the  signal 
indicator  will  flash  even  if a  turn  signal  bulb  is burned  out.  Checkthe front 
and  rear  turn  signal  lights  regularly  to  make  sure they 
are working. 
Operation Of Lights 
Although  your  vehicle’s  lighting  system  (headlights,  parking  \
lights,  fog 
lamps,  side marker  lights  and  taillights)  meets  all  applicable  federal  ligh\
ting 
requirements,  certain  states  and  provinces  may apply  their  own  lighting 
regulations  that  may  require  special  attention  before  you  operat\
e  these 
lights. 
For  example,  some  jurisdictions  may  require  that  you  operate  your  f\
og 
lamps  only  when  your  lower  beam  headlights 
are also on,  or  that  headlights 
be  turned  on  whenever  you  must  use  your  windshield  wipers.  In  add\
ition, 
most  jurisdictions  prohibit  driving  solely  with  parking  lights,  \
especially  at 
dawn  or  dusk.  It is  recommended  that  you  check  with  your  own  state or 
provincial  highway  authority  for applicable  lighting  regulations.

overload,  your  headlights  will  flicker 
on and off. Have  your  headlight 
wiring  checked  right  away  if  this  happens. 
Fog Lamps (Option) 
Use  your  fog lamps 
for  better  vision  in 
foggy  or misty 
conditions.  Your 
parking  lights  and/or  low  beam  headlights 
must  be 
on or your 
fog  lamps  won't  work. 
The  fog lamp  switch 
is  on  the  instrument 
panel  under  the 
headlight  switch. 
Press  the  left  side  of  the  switch  to  turn  the  fog  lamps  on,  and  the  right  side 
of  the  switch 
to turn  them  off. A light  will  glow  in  the  right  side  of  the 
switch  when  they  are on. 
Remember,  fog  lamps  alone  will  not  give  off  as much  light  as your 
headlights. 
Never 
use your  fog lamps  in  the  dark  without  turning  on  your  headlights. 
Fog  lamps  will  go 
off whenever  your  high  beam  headlights  come  on. When 
the  high  beams  go  off,  the  fog  lamps  will  come 
on again.

Warning  Lightsy  Gages  and  Indicators 
This  section  describes  the  warning  lights  and  gages that may  be  on  your 
vehicle.  The  pictures  will  help  you  locate  them. 
Warning  lights  and  gages  can  signal  that  something  is  wrong  be\
fore  it 
becomes  serious  enough  to  cause  an  expensive  repair  or  replacem\
ent. 
Paying  attention  to  your  warning  lights  and  gages  could  also  s\
ave  you  or 
others  from  injury. 
Warning  lights 
go on  when  there  may  be  or  is  a problem  with  one  of your 
vehicle’s  functions. 
As you  will  see in the  details on the  next few pages, 
some  warning  lights  come  on  briefly  when  you  turn  the  ignition\
  key  just to 
let  you  know  they’re  working.  If  you  are  familiar  with  this  sec\
tion,  you 
should  not 
be alarmed  when  this  happens. 
Gages  can  indicate  when  there  may  be or  is  a problem  with  one 
of your 
vehicle’s  functions.  Often  gages  and  warning  lights  work  toge\
ther  to let  you 
know  when  there’s  a problem  with  your  vehicle. 
When  one  of the  warning  lights  comes  on  and  stays  on  when  you  are 
driving,  or  when one of the  gages  shows  there  may  be  a problem,  check  the 
section  that  tells  you  what to 
do about  it.  Please  follow  the  manual’s  advice. 
Waiting  to  do  repairs  can  be  costly 
- and  even  dangerous. So please  get  to 
know  your  warning  lights  and  gages.  They’re  a big  help.

A computer  monitors  operation of your fuel,  ignition  and  emission  control 
systems.  This  light should  come  on  when  the ignition 
is on, but the engine  is 
not  running,  as  a check  to  show  you  it is  working. 
If it does  not  come on at 
all,  have  it fixed  right  away. 
If it  stays  on, or it comes on while  you are 
driving,  the  computer is indicating  that  you  have  a problem. You should 
take  your  vehicle  in for service  soon. 
NOTICE: 
If you  keep  driving  your  vehicle  with  this  light on, after  a  while 
the  emission  controls  won’t  work  as  well,  your  fuel  economy \
won’t  be  as  good  and  your  engine  may 
not run  as  smoothly.  This 
could  lead  to  costly  repairs  not  covered  by  your  warranty.

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.

FM  Stereo 
FM stereo  will  give  you  the  best  sound.  But FM signals will reach  only 
about 
10 to 40 miles (16 to 65 km). And,  tall  buildings  or  hills  can  interfere 
with  FM  signals,  causing  the sound  to  come  and  go. 
AM 
The  range  for most  AM stations  is greater  than  for FM, especially  at  night. 
The  longer  range,  however,  can  cause  stations  to  interfere  with  eac\
h  other. 
AM can  pick  up  noise  from  things  like  storms  and  power  lines.  Tr\
y  reducing 
the  treble  to  reduce  this  noise  if  you ever  get 
it. 
AM  Stereo 
This  means  the  Delco’ system  can  receive  C-QUAM’ stereo  broadcasts. 
Many  AM  stations  around  the  country  use  C-QUAM@  to  produce  ste\
reo,  though  some 
do not.  (C-QUAM@ is a  registered  trademark  of Motorola, 
kc.)  If  your  DelcoB  system  can  get  C-QUAM@,  your  “STEREO’ light will 
come  on  when  you’re  receiving  it. 
NOTICE: 
Before you add  any  sound  equipment  to  your  ~ehicle - like  a 
tape  player, 
CB radio,  mobile  telephone  or two-way  radio - be 
sure  you can  add 
what you  want. If you can, it’s very important 
to  do 
it properly.  Added  sound  equipment  may interfere  with the 
operation  of your  vehicle’s  engine, Delco@  radio  or  other 
systems,  and even  damage  them. And,  your  vehicle’s systems 
may  interfere  with the  operation  of sound  equipment  that  has 
been  added  improperly. 
So, before  adding  sound  equipment,  check  with your  dealer  and 
be  sure  to  check Federal  rules  covering mobile  radio  and 
telephone  units.

Loss of 0 mo/ 
Let’s  review  what  driving  experts  say  about  what  happens  whe\
n  the  three 
control  systems  (brakes,  steering  and  acceleration)  don’t  ha\
ve  enough 
friction  where  the  tires  meet  the  road  to  do what  the  driver  has  asked. 
In  any  emergency,  don’t  give  up.  Keep  trying  to  steer  and  \
constantly  seek 
an 
escape  route  or  area of less  danger. 
Skidding 
In  a  skid,  a  driver  can  lose control  of the  vehicle.  Defensive  drivers  avoid 
most  skids  by  taking  reasonable  care  suited  to  existing  conditi\
ons,  and  by 
not  “overdriving”  those  conditions.  But  skids  are  always  p\
ossible. 
The  three  types  of skids  correspond  to  your  Vehicle’s  three  control  systems. 
In  the  braking  skid  your  wheels  aren’t  rolling. 
In the  steering  or  cornering 
skid,  too  much  speed  or steering  in  a  curve  causes  tires  to  slip  and  lose 
comering  force.  And  in  the  acceleration  skid  too  much  throttle  causes  t\
he 
driving  wheels  to  spin. 
A cornering  skid  and  an acceleration  skid  are  best  handled  by easing  your 
foot  off  the  accelerator  pedal. 
If  your  vehicle  starts  to  slide,  ease  your  foot off  the  accelerator  pedal  and 
quickly  steer  the  way  you  want 
the vehicle  to  go.  If  you  start  steering 
quickly  enough,  your  vehicle  may  straighten out. Always  be  ready  for a 
second  skid  if  it  occurs. 
Of  course,  traction  is reduced  when  water,  snow,  ice, gravel,  or  other 
material  is 
on the  road.  For  safety,  you’ll  want  to  slow  down  and  adjust  \
your 
driving  to  these  conditions.  It  is  important 
to slow  down  on  slippery 
surfaces  because  stopping  distance 
will be  longer  and  vehicle  control  more 
limited.
