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 I IO-volt AC outlet.
A CAUTION:
Plugging the cord into an ungrounded outlet
l could cause an electrical shock. Also, the wrong
kind
of extension cord could overheat and cause
a tire. You could be seriously injured. Plug the
1 cord into a properly grounded three-prong
110-volt
AC outlet. If the cord won’t reach, use a
l heavy-duty three-prong extension cord rated for
at least 15 amps.
I
4. After you’ve used the coolant heater, be SLUT to 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
a
GM dealer in the area where you’ll be parking yo~~r
vehicle. The dealer can give
you the best advice for that
particular area.

Convex Outside Mirror
Your passenger’s side mirror is convex. A convex
mirror’s surface
is curved so you can see more from the
driver’s seat.
A convex mirror can make things (like other
1 vehicles) look farther away than they really are.

Section 3 Comfort Controls and Audio Systems
In this section you’ll find out how to operate the comfort
control and audio systems offered with your vehicle. Be
sure to read about the particular systems supplied with
your vehicle.
Comfort Controls
This section tells you how to make your air system work
for you. Your comfort control system uses
ozone-friendly
R- I34a 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.

Air Conditioning
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 perfor~nance 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.
Heating
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
0
0
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.
Rear Window Defogger (Option)
You can tell if your vehicle has this option by looking at
the rear window. There will be lines across the glass.
These are the wire-like elements which heat your window.
NOTICE:
Scraping the inside of your rear window could
cut
and damage the defogger. Your warranty
would not cover this damage. Don’t put decals
there; you might have to scrape them
off.
Your vehicle has air vents in the center and on the sides
of your instrument panel.
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 coming out of any vents that are open.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little fdster
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.
