Engine Coolant Heater (Option) 3. Plug it into a normal, grounded 1 10-volt AC outlet.
In very cold weather,
0°F (- 1 8 “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.
‘T
F
C’ J:
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.

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 your windows.

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 Certificatioflire 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
