If equipment such as a cap or camper is installed, your Center High Mount
Stoplamp (CHMSL) will no longer be visible from behind. You should
select a cap or camper with a CHMSL on it or, if one is not available, have
one installed. See your GM dealer about how to connect your vehicle’s
wiring to a cap or camper CHMSL.
Camper Wiring Harness (Option)
An optional 5-wire harness is stored in the front stake pocket on the driver’s
side of the bed. The harness has
no connector, and should be wired by a
qualified electrical technician.
It must be routed out of your vehicle and securely attached so that it won’t
be pulled or rubbed while you’re using it.
Store the harness
in its original position. Wrap the harness together and tie it
neatly so it won’t be damaged.
If a camper is installed, your Center High Mount Stoplamp (CHMSL) will
no longer be visible from behind. You should select a camper with a

it or, if one is not available, have one installed. See your GM
dealer about how to connect your vehicle’s wiring to a camper CHMSL.
Trailer Wiring Harness
7-wire harness is stored under your vehicle along the rear frame
crossmember. The harness connects to the underhood electrical center and
no connector, and should be wired by a qualified electrical technician.
Securely attach the harness to the trailer, then tape or strap it to your
vehicle’s frame rail. Be sure
you leave it loose enough so the wiring won’t
bind or break when turning with the trailer, but
not so loose that it drags on
the ground.

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.
The right knob on the control panel changes the heater 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 airf-low
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 heater 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.

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.

To turn on the rear
window defogger,
press the rear defog
button
next to the fan
control knob.
‘he rear window defogger
will only work if the ignition switch is turned to
:UN.
‘ou can turn the defogger off at any time by pressing the button again. The
efogger
will shut itself off after several minutes, so that the glass does not
et too hot.
If the defogger shuts off, and the window still isn’t clear, turn on
le defogger again.
Ventilation System
Your vehicle‘s
ventilation system
supplies outside air
to
the inside of your
vehicle when
it is
moving. With the side
windows closed, air
will flow into the front
air inlet grilles,
through the vehicle, and out the rear air
exhaust valve.
Outside air
will also enter the vehicle when the heater or the air
conditioning fan is running, unless you have the recirculation button pushed
in.
For more information see “Recirculation Button’‘ in this section.
Ventilation Tips
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.
Your vehicle has air
vents
in the center a1
on the sides of your
instrument panel. nd
You can move the vents from side to side or
up and down to direct the flow
of air. or close the vents altogether. When you close a vent, it will increase
the
flow of' air corning out of any vents that are open.
Audio Systems
Your Delco'E audio system has been designed to operate easily and give
years of listening pleasure.
But you will get the most enjoyment out of it if
you acquaint yourself with it first. Find out what your De1co"system can do
and how to operate all its controls, to be sure you're getting the most
out of
the advanced engineering that went into it.
