Downloaded from www.Manualslib.com manuals search engine NOTICE:
Your engine is designed to work with the
electronics
in your vehicle. If you add electrical
parts
or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer.
If you don’t,
your engine might not perform properly.
If you ever have to have your vehicle towed, see
the part of this manual that tells how to do it
without damaging your vehicle. See “Towing
Your Vehicle” in the Index.

Downloaded from www.Manualslib.com manuals search engine 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.
2.4L Engine
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.
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.

On cold days, use FLOOR 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 ducts.
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 “Engine Coolant
Heater’’ in the Index.
Ventilation System
For mild outside temperatures when little heating or
cooling
is needed, use VENT to direct outside air through
your vehicle. Your vehicle
also has the flow-through
ventilation system described later in this section.
Your vehicle’s flow-through ventilation system supplies
outside air into
the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan
is running.

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
mode knob to
FLOOR and the fan to the highest speed
for a fcw 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 circulate throughout your vehicle.
Defogging and Defrosting Windows
Your system has two settings for clearing the front and
side windows.
To defrost the windows quickly, use
DEFROST with the temperature knob all the way in
the red area.
To warm passengers while keeping the
windows clean, use DEFOG.
To defog the side windows, set the right control to
BI-LEVEL and the fan control to the highest setting.
To defog the side windows while using the air
conditioner, set the right control to BI-LEVEL, the fan
control to the highest setting, and press the
A/C button.
For both systems, aim the side vents toward the side
windows. For increased airflow to the side vents,
close
the center vents.

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 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.
Recreational Vehicle Towing
You can tow your vehicle behind another vehicle for use
at your destination. Be sure
to use the proper towing
equipment designed for recreational towing. Follow the
instructions for the towing equipment.
Towing Your Vehicle from the Front
(With a Dolly)

Follow these steps:
1. Put the front wheels on a dolly.
2. Set the parking brake.
3. Open the fuse panel on the driver’s side of the
instrument panel. Remove the fuse labeled
CLSPCM.
This will keep your battery from draining while towing.
4. Turn the ignition key to OFF to unlock the steering
wheel, see “Ignition Switch’’ in the Index.

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.
Tow a trailer.
If you get the overhear warn J wlm no sign of steam,
try this for a. minute or
so:
1. If you have an air conditioner, 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)
or THIRD (3) for automatic transaxles.
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 slgn 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 ofthe 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.
When you decide it’s safe to lift the hood, here’s what
you’ll see:

it isn’t, you may have a leak in the radiator hoses, heater
hoses, radiator, water pump
or somewhere else in the
cooling system.
’ A C * UTION:
-- I
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.
I NOTICE:

~~ ~
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running.
If the engine is
overheating, the fan should be running. If it isn’t, your
vehicle needs service.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water,
or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle's coolant warning
system is set
for the proper coolant mix. With
plain water or the wrong mix, your engine could
get
too hot but you wouldn't get the overheat
warning. Your engine could catch
fire and you or
others could be burned.
Use a 50/50 mix of clean
water and
DEX-COOL TM antifreeze.
I NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So
use the recommended coolant. You
can be burned if you spill coolant

engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on
a hot engine.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
When adding coolant it is important that you
use DEX-COOL
TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant 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.
What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL TM (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need to add anything else.
Adding only plain water to your cooling system
can be dangerous. Plain water, or
some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system is set
for the proper coolant mix. With
plain water
or the wrong mix, your engine could
get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you
or
others could be burned. Use a 50/50 mix of clean
water and DEX-COOL
TM (orange-colored,
silicate-free) antifreeze.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
If you use an improper coolant mix, your engine
could overheat and be badly damaged. The
repair cost wouldn't
be covered by your
warranty.
Too much water in the mix can freeze
and crack the engine, radiator, heater core and
other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
I
Checking Coolant
The surge tank is located on the passenger side of the
engine compartment.
"urning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little -- when the engine and radiator are hot.
