CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Be sure to turn
off the air bag before using a rear
-facing child
restraint in the right front seat position.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle
-- even when no child is in it.
Where to Put the Restraint
(Crew Cab Models)
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors, therefore, recommends that child
restraints be secured in a rear seat position, including an
infant riding in a rear
-facing infant seat, a child riding in
a forward
-facing child seat and an older child riding in a
booster seat.If your vehicle has air bags and you want to secure a
rear
-facing child restraint in the right front passenger's
seat, turn off the passenger's air bag. See ªAir Bag Off
Switchº and ªSecuring a Child Restraint in the Right
Front Seat Positionº in the Index for more on this,
including important safety information.
CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger's air bag inflates. This is because the
back of the rear
-facing child restraint would be
very close to the inflating air bag. Be sure to turn
off the air bag before using a rear
-facing child
restraint in the right front seat position.
You may secure a forward-facing child restraint
in the right front static seat or right front bench
seat, but before you do, always move the front
passenger seat as far back as it will go. It's better
to secure the child restraint in the rear seat.

Express-Down Feature
The driver's window also has an express
-down feature
that allows the window to be lowered without holding
down the switch. Press and hold the rear of the window
switch labeled AUTO for one second to activate the
express
-down mode.
The express
-down mode can be cancelled at any time by
pressing the front of the switch. To open the window
part way, lightly tap the switch until the window is at the
desired position.
Lockout Feature (If Equipped)
If you have a Crew Cab model with power windows, the
driver's door will have a lockout feature. When
engaged, this feature will prevent all window switches,
except the driver's window switches, from operating.
This switch is located above the four window switches
on the driver's door.. When the switch is not engaged,
all windows will return to normal operation.
Sliding Rear Window (If Equipped)
To open the sliding rear window, unlock the latch
lever by pulling the lever 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 onto the latch plate. Try to open the
window without releasing the latch lever to be sure the
window is in the locked position.

2-18 Gasoline Engine Warm-Up
When you've started your engine, let it run for 20 or
30 seconds to warm up before you put a load on
the engine.
Drive at moderate speeds for the first few miles,
especially in cold weather. Running a cold engine at
high speed can damage it. See ªEngine High Idle
Systemº in the Index if your vehicle has this feature.
Restarting the Gasoline Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, you'll first have to shift the automatic
transmission to NEUTRAL (N). This safety feature
prevents starting the engine when the transmission is
in a drive gear.
Stopping the Gasoline Engine
Let your engine idle for a few seconds before turning it
off after you have finished driving your vehicle.
If you shift to NEUTRAL (N) or PARK (P), set the
parking brake.
If your vehicle has a two
-speed axle, put the range
selector in LOW. To be sure the axle has shifted into
LOW, engage the clutch and transmission; the vehicle
may move slightly when you do this.
While your engine is idling before you turn it off, you
can make a list of any operational or handling concerns
to give to responsible maintenance personnel so they can
handle them right away.
Moisture will condense in a fuel tank that is almost
empty if the engine has not run for a while, even just
overnight under some conditions. So, it's always best to
refuel your vehicle at the end of each run.

2-87 Oil Pressure Gage
United States Canada
The engine oil pressure gage, on the lower right portion
of your instrument panel cluster, shows engine oil
pressure in psi (pounds per square inch) or in kPa
(kilopascals). Oil pressure may vary with outside
temperature and oil viscosity, but readings of 30 to
40 psi (205 to 275 kPa) on gasoline engines at operating
temperature and moderate road speeds are normal. If
you have a diesel engine, the normal operating range
should be between 35 and 70 psi (240 to 480 kPa).A reading in the low pressure zone may be caused by a
dangerously low oil level or other problem.
If you have a Caterpillar

diesel engine, also see your
Caterpillar
Operation & Maintenance Manual.
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

3-3 Heater/Air Conditioning Controls
(If Equipped)
If your vehicle has air conditioning, the heater/air
conditioning control panel will look like this.
Fan Knob
The knob on the left side of the control panel regulates
the fan speed. It has four speeds.
To increase airflow, turn the knob clockwise. To
decrease airflow, turn it counterclockwise. To turn the
fan off, turn the mode knob on the far right all the way
counterclockwise.Temperature Knob
The middle knob on the control panel is used to adjust
the temperature of the air flowing into the passenger
compartment of your vehicle.
Turn the knob toward the red area for warmer air.
Turn the knob toward the blue area for cooler air.
Mode Knob
The knob on the right side of the control panel is used to
select the direction of the air flowing into the vehicle.
(Maximum Air Conditioning): Turn the right
knob to maximum air conditioning 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, turn the
knob clockwise to place the air conditioning system in
the regular air conditioning mode.
(Air Conditioning): This setting is used for
normal cooling on hot days. It cools outside air and
directs it through the instrument panel vents.

Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. The longer side with the tape visible should face
to the right. If the ignition is on, but the radio is off, the
tape can be inserted and will begin playing. If you hear
nothing but a garbled sound, the tape may not be in
squarely. Press the eject button to remove the tape and
start over.
While the tape is playing, use the VOL, AUDIO and
SEEK controls just as you do for the radio. The radio
will display UP if the top side of the tape is playing.
DN (Down) will appear if the bottom side is playing.
If you want to insert a tape while the ignition is off, first
press the eject button or the RCL knob.
If an error appears on the display, see ªCassette Tape
Messagesº later in this section.1 PREV (Previous): Your tape must have at least
three seconds of silence between each selection for
previous to work. Press this pushbutton to go to the
previous selection on the tape if the current selection has
been playing for less than 3 seconds. If pressed when the
current selection has been playing from 3 to 13 seconds,
it will go to the beginning of the previous selection or
the beginning of the current selection, depending on
the position on the tape. If pressed when the current
selection has been playing for more than 13 seconds,
it will go to the beginning of the current selection.
Pressing this pushbutton multiple times will increase the
number of selections to be searched back, up to
-9.
Pressing the NEXT pushbutton will cancel the
selection(s).
2 NEXT: Your tape must have at least three seconds of
silence between each selection for next to work. Press
this pushbutton to go to the next selection on the tape.
Pressing this pushbutton multiple times in the next mode
will increase the number of selections to searched
forward. Pressing the PREV pushbutton will cancel
the selection(s).
