Downloaded from www.Manualslib.com manuals search engine Engine Coolant Heater (Canada Only)
In very cold weather, 0°F (- 18 O 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 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. After you’ve used the coolant heater, be sure 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
your Chevrolet dealer in the area where you’ll be
parking your vehicle. The dealer can give you the best
advice for that particular area.

days. This setting cools outside air and directs it through
the instrument panel vents.
The air conditioning compressor operates in NORMAL
A/C, as well as RECIRCULATE, BI-LEVEL and
DEFROST. It only works when the outside temperature
is above freezing. When the air conditioning compressor
is on, you may sometimes notice slight changes in
your vehicle's engine speed and power. This
is normal
because the system is designed to cycle the compressor
on and
off to keep the desired cooling and help
fuel economy.

Temperature Sensors
Sunload:
This sensor is on top of the instrument panel.
When the inside temperature is increased by sunlight,
the system will lower the inside temperature up to 5
OF
(3 O C) below the setting on the display.
Outside Temperature: This sensor is on the right side
of the upper radiator support in the grille opening. This
is what you usually see on the display.
If the outside temperature goes up, the displayed
temperature will not change until:
0 Vehicle speed is above 25 mph (40 km/h) for at least
0 Vehicle speed is above 45 mph (72 km/h) for one
This delay helps prevent a false reading. If vehicle speed
remains above 25 mph
(40 kmh) or the temperature
goes down, the display is updated immediately.
If your vehicle has been off for more than three hours,
the current outside temperature will be stored in the
system when you start the vehicle.
three minutes, or
and a half minutes.
Inside Temperature: This sensor is in the center air
outlet on the passenger side.
I€ you block or cover either interior sensor (sunload or the
inside temperature), the system will give a false reading.

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, adjust the
fan to the highest speed 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.

Downloaded from www.Manualslib.com manuals search engine Snow can trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see it or smell
it, so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open a window just
a little on the side of the
vehicle that’s away from the wind. This will help
keep
CO out.
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 charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
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.

If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
If .you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (@)
or DRIVE (D) for automatic transmissions. If you no longer have the overheat warning, you can
drive. Just
to be
safe, drive slower for about 10 minutes.
If the warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop, and park your
. vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see
if the warning stops. But then,
if you still have the
warning,
turn oJjcthe engine and get everyone out of
the vehicle until it cools down.
You may decide not to lift the hood but to get service
help right away.
