the road or over road debris.

Don’t pause in NEUTRAL (N) as you shift the transfer case into 4-WHEEL
LOW (4L), or your gears could clash.
Remember that driving in
&WHEEL HIGH (4H) or 4-WHEEL LOW (4L) may
reduce fuel economy.
Also, driving in four-wheel drive on dry pavement could
cause your tires
to wear faster and make your transfer case harder to shift.
Front Axle Locking Feature
The front axle locks and unlocks automatically when you shift the transfer
case. Some delay for the axle to lock or unlock is normal. If the outside
temperature is very hot, or the vehicle has been used under hard driving
conditions, there may be a slight delay for the axle to unlock.
Windows
To open your manual
windows, turn the
hand crank on each
door to raise or lower
your side door
windows.
If you have the
optional power
windows, the controls
are on each of the side
doors.
The driver’s door has a switch for the passenger windows as well.
Your power
windows will work when the ignition has been turned to ACC or RUN.
Push the rear
of the switch with the power window symbol on it to lower the
window.
Push the front of the switch with the power window symbol on
it to raise the
window.

The driver’s window switch also has an “express down” feature that allows
the window to lower without holding the switch. Press and hold the side
of
the window switch marked AUTO for one second to activate the \
express
down mode. The express down mode can be cancelled at any time by
pressing the opposite side of the switch. To open the window part way,
lightly tap the switch until the window is at the desired pos\
ition.
If you have a Crew Cab and power windows, the power window switch has a
lock-ut feature.
This feature prevents the rear windows from operating when
the front drivers-side switch is in the lock-out position. When the switch is
moved out of the lock-out position, the rear power windows will operate again.
Sliding Rear Window (Option)
To open the sliding
rear window, unlock
the latch lever by
moving the lever
toward the driver’s side. Release the lever
from the latch plate
and slide the window
toward the driver’s
side of the vehicle.
To close the window, slide the window toward the passenger’s side of the
vehicle. The latch lever will automatically snap locked on the latch plate. \
Try to open the window without releasing the latch lever to be su\
re the
window is in the locked position.
Swing-Out Windows (Extended Cab)
To open a rear
swing-out window,
just flip the latch open
and swing the glass
out.
The latch will catch when the window is fully open and hold window in the

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.

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.

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

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.

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

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.

coming into your vehicle
to be cooled and directed through the instrument
panel vents. This setting is useful for normal cooling

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.
