Engine Coolant Heater (Option)
2.2L L4 ECOTEC Engine
3400 V6 Engine
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. At temperatures above 32
F (0
C),
use of the coolant heater is not required.

2-25 To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. On
the 2.2L L4 ECOTEC engine, the engine coolant
heater cord is located in front of the coolant surge
tank on the passenger's side of the engine
compartment. On the 3400 V6 engine, the engine
coolant heater cord is located near the engine air
cleaner/filter. See ªEngine Compartment Overviewº
in the Index for more information on location.
3. Plug it into a normal, grounded 110
-volt AC outlet.
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
11 0
-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 dealer in the area where you'll be parking your
vehicle. The dealer can give you the best advice for that
particular area.

Mode Buttons
A/C (Air Conditioning): Press A/C to operate the
air conditioning. The light will glow when the button is
pressed to indicate that the air conditioning system has
been turned on. The fan knob must be set to a speed for
the air conditioning to operate.
(Outside Air): Press this button to force the
system to use outside air.
Pressing this button will cancel the recirculation button.
(Recirculation): Press this button to limit the
amount of outside air entering your vehicle. This is
helpful when you are trying to limit odors entering
your vehicle. Press it again to turn off the recirculation.
Pressing this button will cancel the outside air button.
Recirculation is not available when the defog or front
defroster mode is selected, or when the fan is off. When
recirculation is selected, the air conditioning compressor
will run automatically to help dry the air in the vehicle.
Air Conditioning
The air conditioner and heater work best if you keep
your windows closed while using them. Your vehicle
also has the flow
-through ventilation system described
later in this section.
For normal cooling on hot days, use vent mode with the
temperature knob in the blue area and the A/C button
pressed in.
On very hot days, begin by opening the windows long
enough to let hot inside air escape. This reduces the time
it takes for your vehicle to cool down, which should
help fuel economy.
For quicker cool
-down on very hot days, use vent mode
with the temperature knob all the way in the blue area
and the A/C button pressed in. Begin with the outside air
button pressed for a few minutes, or until the vehicle
begins to feel cool. Then push the recirculation button.
If the recirculation setting is used for long periods of
time, the air in your vehicle may become too dry.

3-4
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
You can use bi
-level with the temperature knob in the
middle and the A/C button pressed in. The system
directs slightly warmer air to your lower body.
Heating
On cold days, use floor mode and the outside air button
with the temperature knob all the way in the red area.
The system will bring in outside air, heat it and send it to
the floor outlets.
Your vehicle has heat ducts that are directed toward
the rear seat. Keep the area under the front seats clear
of obstructions so the heated air can reach the rear
seat passengers.
If your vehicle has an engine coolant heater, you can use
it to help your system provide warm air faster when it's
cold outside (0
F (
-18
C) or lower). An engine coolant
heater warms the coolant your engine and heating
system use to provide heat. See ªEngine Coolant
Heaterº in the Index.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows. For each setting, adjust the temperature
knob as desired.To defrost the front window quickly, turn the
temperature knob all the way in the red area. Use front
defroster and adjust the fan to the highest speed. To
warm passengers while keeping the front window clean,
use defog. When you switch to defog or defrost modes
your system will automatically move from recirculation
into outside air. When you move the mode knob back to
vent or bi±level, the system will move back into
recirculation. When the car is turned off and back on the
system will default to outside air automatically.
The recirculation setting in cold weather should be used
only for outside odor control so that fog formation on
the windows is reduced.
Your vehicle is equipped with side window defogger
vents. The side window defogger vents are located
above the side instrument panel vents. To defrost the
side windows, turn the temperature knob all the way in
the red area. Use floor mode and adjust the fan to the
highest speed.
To defog the side windows while using air conditioning,
use bi
-level and adjust the fan to the highest speed and
press the A/C button so that the indicator light is glowing.
For added airflow to the side windows, aim the side vents
toward the windows and close the center vents.

3-6
You will find air outlets in the center and on the sides of
your instrument panel.
You can direct the airflow side to side by moving the
sliding levers. The outlet louvers can also be tilted up
and down. To control the amount of airflow through the
outlets, turn the thumbwheel.Ventilation Tips

Keep the hood and the area around the windshield
wipers free of ice, snow or any other obstruction,
such as leaves. The heater and defroster will work
better, reducing the chance of fogging the inside
of your windows.

Keep the air path under the front seats clear
of objects to help air circulate throughout
your vehicle.

When an objectionable odor outside the vehicle is
encountered, the recirculation setting can prevent the
odor from being drawn into the vehicle through the
ventilation system. For example, this usage of
recirculation can be helpful when driving through a
long tunnel with poor ventilation. However,
extended use of recirculation in cold or cool
weather can cause window fogging.

4-29
CAUTION:
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 a while.
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.

5-10
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.
If No Steam Is Coming From Your Engine
An overheat warning, along with a low coolant light,
can indicate a serious problem. See ªLow Coolant
Lightº in the Index.
If you get an engine overheat warning with no low
coolant light, 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.

Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. If your air conditioner is on, turn it off.
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 (D) for
an automatic transaxle, or for a manual transaxle
shift to FIFTH (5) or FOURTH (4).
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, idle the engine for three
minutes while you're parked. If you still have the
warning, turn off the 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.

5-12
The coolant level should be at or above the FULL COLD
mark. If it isn't, you may have a leak at the pressure cap
or in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
If there seems to be no leak, with the engine on, check to
see if the electric engine cooling fans are running. If the
engine is overheating, both fans should be running. If
they aren't, your vehicle needs service.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.

5-13
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL
(silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL
is not
covered by your new vehicle warranty.
How to Add Coolant to the Coolant
Surge Tank
NOTICE:
This vehicle has a specific coolant fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
If you haven't found a problem yet, check to see if
coolant is visible in the surge tank. If coolant is visible
but the coolant level isn't at or above the FULL COLD
mark, add a 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant at the coolant surge tank, but be
sure the cooling system, including the coolant surge tank
pressure cap, is cool before you do it. See ªEngine
Coolantº in the Index for more information.
