Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Option)
In very cold weather, 0°F (- 18 "C) or colder, the engine
coolant heater can help. You'll get easier starting and
better fuel economy during engine warm-up. Usually,
the coolant heater should be plugged
in a minimum of
four hours prior to starting your vehicle.
To Use the Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt AC outlet.
A I
I /! CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong 110-volt
AC outlet. If the cord won't reach, use a
heavy-duty three-prong extension cord rated
for
at least 15 amps.
4. Before starting the engine, be sure to unplug and store
the cord as
it was before to keep it away from moving
engine
parts. If you don't, it could be damaged.
How long should
you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of
oil you have, and some other things. Instead of
trying to list everything here, we ask that
you contact
your
GM dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Inside Mirror
Push or pull the tab under
the mirror to red1 Jce glare
from headlamps behind you after dark.
Outside Mirrors
Adjust your outside mirrors so you can just see the
side of your vehicle, and have a clear view
of objects
behind
you. Some mirrors can be folded in to enter
narrow doorways.
Electric Outside Rearview Mirrors (Option)
If you have electric mirrors, they can be adjusted to
point where you want from inside the vehicle. Select
the mirror you want
to move
by rotating the
switch clockwise to adjust
the passenger side mirror
and counterclockwise
to adjust the driver side
mirror. The center
position is neutral.
Then, adjust the mirror angle by pressing the outer
arrows on the switch until the mirror is adjusted where
you want
it.
Your electric outside
rearview mirrors can be
defrosted by pressing the
switch next
to the heater
controls. (See "Comfort
Controls" in the Index).

Downloaded from www.Manualslib.com manuals search engine Comfort Controls
This section tells you how to make your air system
work for you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these
systems, you can control the heating,
cooling and ventilation
in your van. Your vehicle also
has a flow-through ventilation system described later
in this section.
Heater Controls
If your vehicle does not have air conditioning, your
heater controls will look like this.
Fan Knob
The left knob of the heating system control panel
controls the fan speed. The knob has four speed
positions. To increase airflow, move the knob toward
HI. To decrease airflow, move it toward LO. To turn the
fan off, move the mode knob on the far right to OFF.
Temperature Knob
The middle knob 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 clockwise toward the red
area for warmer air. Move the knob counter clockwise
toward the
blue area for cooler air.

Before using your vehicle’s air conditioning, open the
windows
to clear the vehicle of hot air.

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

If you have a rear heater (without rear air conditioning),
the control switch is located on the instrument panel.
To increase and decrease the flow
of heated air to the
rear floor vents, move the switch marked REAR HEAT
to the blower speed you want.
The
knob has three speed positions. To increase the flow
of heated air, move the switch toward HIGH. To turn the
fan
off, move the switch to OFF.
Rear Air Conditioning and Rear Heater
If your vehicle has a rear air conditioning and rear
heater system combination, controls are provided to
regulate the temperature, location and speed
of
the airflow.
Front Passenger Control
To adjust the air temperature, turn the temperature knob
on the right side
of the control panel.

Downloaded from www.Manualslib.com manuals search engine Air Conditioning Heating
Before using your
vehicle’s air conditioning, open the
windows to clear the vehicle of hot air. This reduces the
time it takes for your vehicle
to cool down. Then keep
your windows closed for the air conditioner to work at
its best.
You can use MAX
A/C with the temperature knob in the
blue area, when it’s really hot outside and you need to
cool the inside air quickly. MAX A/C lets in only a little
air from the outside.
If you first use MAX
A/C, you can then use A/C with
the temperature knob in the blue area, as
soon as the
vehicle has cooled down,
so outside air will be going
through your vehicle.
If your vehicle has rear air conditioning, setting it on
LO may enhance front A/C performance by allowing
trapped refrigerant in rear lines to circulate.
When the air conditioning, DEFROST or BLEND is on,
you may notice a slight increase or decrease in engine
speed, due to compressor operation. This is normal
because the system is designed to cycle the compressor
on and off to keep the desired temperature. On
cold days, use HEATER with the temperature knob
in the red area. Outside air will be brought in through
the floor outlets. The heater works best if you keep your
windows closed while using it.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See “Engine Coolant Heater” in the Index.
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 yow windows.

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This
saves fuel. When
you run the engine, make it go a
little faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that
you get
and it keeps the battery (or batteries) charged.
You will
need a well-charged battery (or batteries) to restart the
vehicle, and possibly for signaling later
on with your
headlamps. Let
the heater run for awhile. If you have a
diesel engine you may have to run it at a higher speed
to get enough heat.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it
as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

The CertificatiodTire label is found on the rear edge
of the driver’s door. The label shows the size of your
original tires and the inflation pressures needed
to obtain
the gross weight capacity of your vehicle. This is called
GVWR (Gross Vehicle Weight Rating). The
GVWR
includes the weight of the vehicle, all occupants, fuel
and cargo.
