Comfort Controls
With this system, you can control the
heating and ventilation
in your Chevrolet.
If you have the air conditioning option,
you can also control cooling.
Your vehicle also has the flow-through
ventilation system described later
in this
section.

Temperature Control Knob
Turn the knob to change the temperature
of the air flowing from the heating
system. Turn
it to the right for warmer air
and to the left for cooler air. The
temperature
of the air can not be less than
the temperature
of the outside air.

vents.
*d : Air is directed through the upper air
vents and the heater ducts.
*A : This setting directs most of the air
through the heater ducts and some of the
air through the windshield defroster vents.
39 : Air is directed through the
windshield defroster vents and the heater
ducts.
9 : This setting directs most of the air
through the windshield defroster vents
and some

Heating
The heater works best if you keep your
windows closed while using it.
1. Turn the air control knob to */I .
2. Turn the fan control knob to the right.
3. Turn the temperature control knob to a
comfortable setting.

Downloaded from www.Manualslib.com manuals search engine During initial start-up only, if your
vehicle is equipped with an optional
engine coolant heater, you can
use it in
cold weather (around +2OoF/-8”C or
lower) to heat the passenger area better
than without
it. Because an engine coolant
heater warms the engine coolant, your
vehicle’s heating system can more
efficiently provide heat for the passenger
area of your vehicle. See “Engine Coolant
Heater’’
in the Index.
Bi-Level Heating
You may want to use bi-level heating on
cool, but sunny days. This setting directs
cool air toward
your body and warmer air
toward your feet.

Air Conditioner Controls (OPTION)
The air conditioning system uses the
same controls as the heating system,
except that the air control knob has two
extra settings, described below. For an
explanation of all
the controls, see
“Heater Controls” earlier
in this part.
MAX: Provides maximum cooling or
quick cool-down
on very hot days. This
setting recirculates most
of the air inside
your vehicle. If
it is used for long periods
of time, the air may become dry. This
setting directs
air through the upper air
vents.
. . ,110
A/C: Use for normal cooling on hot days.
This setting cools outside air and directs
it through the upper air vents,
The air conditioner compressor operates
in “MAX,” “A/C” and in qd , *% and
9 when the outside temperature is
above freezing. When the air conditioner
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.
Cooling
The air conditioner works best if you keep
your windows closed. On very hot
days,
open the windows just long enough for
the hot air to escape.
1. Turn the air control knob to “A/C” for
normal cooling. For faster cooling
move the knob to
“MAX.”
2. Turn the temperature control knob to
a comfortable setting.
3. Turn the fan control knob to the right.

Highway Hypnosis
Is there actually such a condition as
“highway hypnosis”? Or is it just plain
falling asleep at the wheel? Call
it
highway hypnosis, lack of awareness, or
whatever.
There is something about an easy stretch
of road with the same scenery, along with
the hum of the tires
on the road, the drone
of the engine, and the rush
of the wind
against the vehicle that can make you sleepy. Don’t
let it happen to
you! If it
does, your vehicle can leave the road in
less than a second, and you could crash
and be injured.
What can you do about highway
hypnosis? First, be aware that
it can
happen.
Then here are some tips:
Make sure your vehicle is well
ventilated,
with a comfortably cool
interior.
Keep your eyes moving. Scan the road
ahead and
to the sides. Check your
rearview mirrors and your instruments
frequently.
If you get sleepy, pull
off the road into
a rest, service, or parking area and
take
a nap, get some exercise, or both.
For safety, treat drowsiness on the
highway as an emergency.
Hill and Mountain
Roads
Driving on steep hills or mountains is
different from driving
in flat or rolling
terrain.
If you drive regularly in steep
:ountry, or
if you’re planning to visit
there, here are some tips that can make
your trips safer and more enjoyable.
Keep your vehicle
in good shape.
Check all fluid levels and also the
brakes, tires, cooling system and
transmission. These parts can work
hard on mountain roads.
Know how to go down hills. The most
important thing
to know is this: let
your engine do some of the slowing

Driving on Grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes
so much
that they would get hot and no longer
work well.
On a long uphill grade, shift down and
reduce your speed to around
45 mph
(70 kmh) to reduce the possibility of
engine and transmission overheating.
If you are towing a trailer and you
have an automatic transmission with
Overdrive, you may prefer to drive
in “D’
instead of Overdrive (or, as you need to,
a lower gear). Or,
if you have a manual
transmission with fifth (or sixth) gear
and you are towing a trailer, it’s better
not to use fifth (or sixth) gear. Just drive
in fourth gear (fifth gear if you have a
six-speed manual transmission) (or, as you
need to, a lower gear).
Parking on Hills
You really should not park your vehicle,
with a trailer attached, on a
hill. If
something goes wrong, your rig could
start to move. People can be injured, and both your vehicle and the trailer can be
damaged.
But if you
ever have to park your
rig on a
hill, here’s how to do it:
1. Apply your regular brakes, but don’t
shift into
“P’ (Park) yet, or into gear
for a manual transmission.
2. Have someone place chocks under the

trailer wheels.
4. Reapply the
regular brakes. Then
apply your parking brake, and then
shift to
“P” (Park), or “R” (Reverse)
for a manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave after
Parking on a Hill
1. Apply your regular brakes and hold
the pedal down while you:
Start your engine;
0 Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear

store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often
when you’re pulling a trailer. See the
Maintenance Schedule for more on this.
Things that are especially important in
trailer operation are automatic
transmission fluid (don’t overfill), engine
oil, axle lubricant, belts, cooling system,
and brake adjustment. Each of these is
covered in this manual, and
the Index will
help you find them quickly. If you’re
trailering, it’s a good idea to review these
sections before you start your
trip.
Check periodically to see that all hitch
nuts and bolts are tight.

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:
If you get the overheat warning but see or
hear no steam, the problem may not be
too serious. Sometimes
the engine can gel
a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
0 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 you have an air conditioner, turn it
2. Turn on your heater to full hot at the
off.

the
window as necessary.
3. Tr!
to keep your engine under load
(in a drive gear where the engine runs
slower).
[f you no longer have the overheat
warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the
warning doesn’t come back on,
you can
drive normally.
[f 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
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.
Cooling System
When you decide it’s safe to lift the hood,
here’s what you’ll see on the
V6 engine:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fan
. . .158

Downloaded from www.Manualslib.com manuals search engine On the V8 engine you’ll see this:
1. Coolant recovery tank
2. Radiator pressure cap
3. Electric engine fans
A CAUTION:
An electric fan under the hood can
start up even when the engine is not
running and can injure
you. Keep
hands, clothing and tools
away from
any underhood electric fan.
II
If the coolant inside the coolant recovery
tank is boiling, don’t do anything else
until it cools down.
When
it is cool, remove the coolant
recovery tank cap and look at
the dipstick.
The coolant level should be at or above
“FULL COLD.” If 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 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.
NOTICE:
Engine damage from running your
engine without coolant isn’t covered
by your warranty. I
If there seems to be no leak, 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.

How to Add Coolant to the Coolant
Recovery Bank
If yon .haven’t found a problem yet, but
the COOhint level isn’t at ur above the
“FULL COLD” mark, add a 50/50
mixture of clew wata (preferably
distilled) and a proper antifreeze at the
coolant‘rtyxwery ta&. (see “~nginef
Coolant” in the Index for more infor-
mation about the prop coolaat mix.)

NOTICE:
I
In cold weather, water can freeze and
crack the engine, radiator, heater core
and other parts. Use the warn-
mended coolant.
When the coolant in the coalant recovery
tank is at or above the “FULL GOLD”
mark, .start your vehicle.
If the overheat warning continues, there’s
one more thing you can try. You can add
the proper coolant mix directly to the
radiator, but be sure the cooling system is
cool before you do it.

(3.4L L32 (Code S) Engine)
1. You can remove the radiator pressure
cap when the cooling system,
including
the radiator pressure cap ant
upper radiator hose, is no longer hot.
Turn the pressure cap slowly to the
left until it first stops. (Don’t press
down while turning the pressure cap.)
If
you hear a hiss, wait for that to stop
A hiss means there is still some
pressure left.
2. Then keep turning the pressure cap,
but now push down as
you turn it.
Remove
the pressure cap.
