Listed are four situations you may experience with your  f~~el gage: 
At the gas station. the fuel pump shuts  off before  the gage reads  full. 
It lakes a little more or less  fuel  to fill up  than  the  fuel gage indicated. 
For  example,  the gage  may have  indicated  the  tank  was  half 
full, but it 
actually took a little more  or less  than  half  the tank's  capacity to fill the 
, tank. 
The  gage  moves a little when  you turn a corner or speed  up. 
The  gage  doesn't go back  to  empty when  you turn off the ignition. 
None  of these indicate 
a problem with the  fuel  gage. 
For information on how to fill your fuel tank,  see "Fuel - Filling  Your 
Tank" 
in the Index. 
For your  fuel tank  capacity,  see "Fuel  -Tank  Capacity" in the Index. 
Engine  Coolant  Temperature  Gage 
This  gage  shows  the engine  coolant  temperature. Most of  the time. the gage 
pointer 
will show your coolant  temperature  at 2 10°F (99"C), or  less. But, if 
you  are pulling a heavy  load or driving LIP hills, your coolant temperature 
may  rise and 
fall near  the  red  260°F ( 128°C) mark. This is normal. If the 
gage  pointer  moves to the  red  260°F 
(128°C) mark, your engine  is too hot! 
It means that your engine coolant  has overheated. You should pull off the 
road, 
stop your vehicle.  and  turn off the engine as soon as possible. 
Hot Coolant Can Burn  You  Badly! 
In "Problems  on  the Road," this manual  shows what to do. See "Engine 
Overheating" 
in thc Index.

Comfort  Controls  and Audio Systems 
Secfion 
In this  section you’ll find out how  to  operate  the comfort  control  systems 
and  audio  systems  offered  with your vehicle. Be  sure to read  about  the 
particular  system  supplied with your vehicle. 
Comfort Controls 
Heater Controls 
If your vehicle  does not have  air  conditioning,  your heater  controls  will look 
like this. 
The  knob  on the left  side of the heating  system control  panel  controls the 
fan  speed.  The  knob has four speed positions.  To increase the  air flow,  move 
the 
knob toward HI. To decrease  the air flow, move it toward LO. To turn 
the  fan  off,  move the  knob to 
OFF.

Before using your  vehicle's air  conditioning. open  the windows  to clear  the. 
vehicle  of  hot air. 
Using the recirculation  function  can also help. See "Recirculation Buttor:" 
in this section for more  information. 
The  knob  on  the  left  side of the heating  system control  panel controls  the 
fan  speed.  The knob  has four speed  positions. To increase  the air 
flow. move 
the  knob toward 
HI. To decrease  the air flow. move it toward LO. To turn 
the  fan  off. move  the knob 
to OFF. If you  have  the air conditioner  on. 
moving  the fan knob 
to OFF also turns off'  the A/C compressor. 
The  middle knob  on the control  panel lets you  select  the relative 
temperature  of the  air  flowing  into  the passenger 
area of your  vehicle.  This 
knob 
will allow  you to adjust  the relative  air temperature  independently of' 
the function  knob setting. Move  the knob  right  toward  the  red area  for 
warmer air. Move  the knob  left toward the blue area for  cooler air. With 
A/C 
on,  move the knob  to  MAX for maximum  cooling. 
This  setting  puts the system 
in the recirculation  mode  and helps to maximize 
your  air conditioner's  performance and your vehicle's  fuel economy.  This 
setting  also  cools  the air the  fastest.  After the vehicle's  interior reaches 
a 
comfortable  temperature,  move the knob  clockwise  to place the air 
conditioning  system 
in the  normal mode. 
The  right  knob 
on the control  panel changes  the heatedair  conditioning 
setting. 
VENT - This  setting, with the  arrow pointing  at the  figure's  head. directs 
air  through  the instrument  panel vents. 
VENT/HEAT 
- Use  this setting, with the arrows  pointing at the figure's 
feet  and head,  to divide airflow between  the heater  floor vents  and 
instrument panel  vents. 
HEAT 
- This  setting. with the  arrow pointing  at  the figure's  feet. directs  air 
through the  heater  floor  vents. This setting  is  useful  for cold weather. 
HEAT/DEFROST 
- Use this  setting, with the arrow pointing  at  the figure's 
feet  and  the  defroster  symbol near the  figure's head. to divide airflow 
between  the heater  floor vents and windshield. 
DEFROST 
- This  setting with the  defrost symbol  directs  air  through the 
windshield  defroster vents. This setting  is  useful  when  you  have fog 
or ice 
on  the windshield. 
The  control  knob can  be placed 
in any position  between  two  heatedair 
conditioning  settings  to  blend  the flow 
of air. The  closer  the knob is to a 
setting  symbol,  the  more the air flow will represent  that symbol's  air  flow 
arrows. 
RECIRCULATION 
BUTTON - This  button,  between the left and middle 
knobs,  allows the air inside your vehicle 
to be recirculated.  This  setting 
helps  to  maximize  your  air  conditioner's  performance  and your vehicle's 
3-3

fuel economy. This setting also  cools the air  the fastest and can  be  used to 
keep  “unwanted odors”  and/or dust from  entering the vehicle. When  using 
the air conditioner,  turn  off recirculation  after  the vehicle reaches 
a 
comfortable  interior temperature. 
When 
the right  knob  on the control  panel is between  HEAT  and DEFROST, 
the recirculation  feature will  not  function. 
A/C - This button, between the middle and  right knobs. allows  the air 
coming  into your  vehicle 
to be cooled and directed through the instrument 
panel  vents. This setting  is  useful for normal  cooling 
on hot days. When  you 
first  use 
A/C with the recirculation  button pushed in, turn off recirculation 
as soon as the vehicle reaches  a  comfortable interior temperature. 
Engine  Coolant  Heater 
If your vehicle has  a diesel  engine, it is equipped with  an engine  coolant 
heater. 
An engine  coolant heater  is optional on gas  engine  vehicles. If you 
use  the engine  coolant heater before starting your  engine 
(in cold weather 
(20” F, (-8” C),  or lower) your heating  system will produce warmer  air 
faster, to heat the passenger  compartment 
in cold weather. 
The  use 
of an engine  coolant  heater also reduces the time it takes for the 
engine  to  reach normal  operating  temperature.  and shortens  the time it takes 
the heater 
to reach full output. For more information,  See “Engine  Coolant 
Heater”  in  the Index. 
Diesel  Engine  Heater  Output 
If you idle your diesel  engine for a long time  when  it’s cold outside, your 
heater  may blow out  cool  air. This is normal. When  you increase  the engine 
speed,  your heater  should  blow out warmer  air. 
If it doesn’t, your coolant 
level  may be too  low. See “Engine  Coolant” 
in the Index  to see  how  to 
check  your  coolant level. 
Rear  Window  Defogger  (Option) 
You can tell if your vehicle has this option  by looking  at the rear window. If 
you see lines running across the glass,  you have it. These  are the  wire-like 
elements  which  heat  your window. 
I NOTICE: 
Scraping  the  inside of your  rear  window  could  cut  and  damage 
the  defogger. 
Your warranty  would  not  cover  this  damage. And, 
don’t  put  decals  there, you might  have  to  scrape  them off. 
For best  results,  clear  the window of as much snow  or ice  as possible  first.

Making  Turns 
I NOTICE: 
Making  very  sharp  turns  while  trailering  could  cause  the  traile\
r to  come  in  contact  with  the  vehicle.  Your vehicle  could  be 
damaged.  Avoid  making  very  sharp  turns  while  trailering. 
When  you’re  turning  with a trailer, make wider  turns than normal. Do this 
so your  trailer won’t  strike  soft  shoulders,  curbs,  road signs,  trees,  or  other 
objects.  Avoid jerky  or  sudden maneuvers.  Signal well in  advance. 
Turn  Signals  When  Towing  a Trailer 
When  you tow a trailer, your  vehicle has to have  extra wiring  (included  in 
the  optional  trailering package).  The green  arrows 
on your instrument  panel 
will  flash  whenever 
you signal  a  turn or lane  change.  Properly  hooked up, 
the  trailer  lamps  will also  flash,  telling other  drivers  you’re  about  to  turn, 
change  lanes  or  stop. 
When  towing  a  trailer, the green  arrows  on your  instrument  panel  will flash 
for 
turns even  if the  bulbs  on the trailer  are burned  out.  Thus, you  may  think 
drivers  behind 
you are  seeing  your  signal  when they are not. It’s important 
to  check  occasionally  to be sure the trailer  bulbs  are still working. 
Driving On Grades 
Reduce  speed  and  shift to a  lower  gear before you start down  a  long  or  steep 
downgrade.  If 
you don’t shift down,  you might  have  to use your  brakes so 
much  that  they  would get hot  and  no longer  work well. 
On 
a long  uphill  grade,  shift  down  and  reduce  your  speed to around 45 mph 
(70 kmh) to reduce  the  possibility of engine and transmission  overheating. 
If  you  have an automatic  transmission 
you should use  DRIVE (3) (or, as 
you need to,  a  lower  gear)  when towing  a  trailer. Operating  your  vehicle in 
DRIVE (3) when towing  a  trailer  will minimize  heat build-up  and extend 
the life 
of your  transmission. 
If  you  have  a  manual  transmission  and 
you are  towing  a trailer, it’s better 
not to use  FIFTH (5) gear. Just  drive in FOURTH (4) gear (or, as you need 
to, a  lower  gear).

When towing at high  altitude on steep  uphill grades,  consider  the following: 
Engine  coolant  will boil at a lower temperature than  at normal altitudes.  If 
you turn your engine off immediately  after towing at high altitude on steep 
uphill grades, your vehicle 
may show signs similar to engine  overheating. 
To avoid this, let the  engine  run while parked  (preferably  on  level ground) 
with the automatic transmission 
in PARK  (Pj  (or  the manual transmission 
out 
of gear  and the parking brake  applied) for a few minutes before turning 
the  engine  off. 
If you do  get  the overheat warning,  see “Engine 
Overheating” 
in the Index. 
Parking on Hills 
You really should not  park your  vehicle,  with a trailer attached, on a hill.  If 
something  goes wrong, your rig could  start to move. People can  be injured, 
and both your vehicle and  the trailer can  be damaged. 
But 
if you  ever  have  to park your rig  on a hill, here’s how to do it: 
1. 
2. 
3. 
4. 
5. 
6. 
Apply your regular brakes,  but don’t  shift into PARK (P) yet, or in gear 
for  a  manual transmission. 
Have  someone  place chocks  under the trailer wheels. 
When the  wheel chocks  are 
in place, release the regular brakes until the 
chocks  absorb  the load. 
Re-apply  the regular brakes.  Then apply your parking brake, and then 
shift 
to PARK  (P),  or  REVERSE (Rj for  a manual transmission. 
If  you  have 
a four-wheel-drive  vehicle, be sure  the transfer  case is in a 
drive  gear-not  in  NEUTRAL 
(N). 
Release the regular brakes. 
A CAUTION: 
It can  be dangerous  to  get out of your  vehicle  if the shift  lever  is 
not  fully  in 
PARK  (P) with the parking  brake  firmly set.  Your 
vehicle  can rofl. 
If you  have  Ieft the engine  running, the  vehicle can move 
suddenly.  You or others  could  be  injured. 
To be sure  your  vehicle 
won’t  move,  even  when  you’re  on  fairly level ground,  use the 
steps  that follow. 
If you have  four-wheel  drive and your transfer  case is in 
NEUTRAL  (N), your vehicle  will  be  free to roll,  even  if your 
shift lever  is  in 
PARK (P). So, be sure  the  transfer  case is in a 
drive  gear 
- not in NEUTRAL  (N).
