You can select temperatures from 65 "F (18°C) to 85°F (29°C). And, at
each end, you may choose
60 " F (16 " C), for maximum cooling, and 90" F
(33 " C), for maximum heating. We recommend when first getting familiar
with your vehicle, select
75 " F (24 " C). You may find that your own personal
comfort requires a slightly higher or lower setting. Once you set the
temperature, the system will automatically maintain the set temperature.

ECON
With this setting it's all automatic, but the air conditioning compressor
does not operate and it won't remove humidity from the air. However,
the system will try to keep the air at the selected temperature. Use this
setting in cold or cool weather to save fuel.
If it's warm outside and you need to cool the air, use the next choice.
AUTO
With this setting, the air conditioning compressor cycles when needed to -_
cool the air and it's all automatic. In cold weather when the system senses
the need for heat,
the air flow will be directed out the floor ducts. As the
interior temperature approaches the desired setting, the blower speed
will decrease and the air
flow could be directed through the defroster and
floor ducts.
To maintain interior comfort, the air flow may move to the air
outlets and floor ducts (Bi-level). On bright sunny days in cold weather,
the air
flow could even come out the A/C outlets to maintain comfort and --
prevent stuffiness.

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 km/h) or less to reduce the possibility of engine and transaxle
overheating.
If your trailer weighs more than 1,000 pounds (450 Kg) and you have an
automatic transaxle with Overdrive, you may want
to drive in “3” instead
of Overdrive
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:
Apply your regular brakes, but do not shift into “P’, (Park).
Have someone place chocks-under the- trailer wheels.
When. the wheel chocks are in place, release the regular brakes until
the chocks absorb the load.
Reapply the regular brakes. THen shift into “P7, (Park) firmly and
apply your parking brake.
Release the regular brakes.
When You Are Ready to Leave Afler Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
0 Be sure the parking brake has released.
2. Let up on the brake pedal.

Should a low coolant condition exist and the stop “STOP ENGINE
ENGINE OVERHEATING” message is displayed, an overheat
protection mode which alternates firing groups
of four cylinders helps
prevent engine damage. This operating mode allows your vehicle
to be
driven to a safe place in an emergency. You may drive up to 50 miles (80
km). Towing a trailer in the overheat protection mode should be avoided.
NOTICE:
After driving in the “Overheated Engine Protection Operating
Mode”, to avoid engine damage allow the engine to cool befo\
re
attempting any repair.
The engine oil may be severely degraded. Change the oil and
reset the oil life indicator. (See “Engine Oil, When to Change”
in the Index.

Engine damage from running your engine without coolant isn’t \
covered
by your warranty. See “Overheated Engine Protection
Operating Mode” in the Index.
If there seems to be no leak, check to see if the electric engine fans are
running. If the engine is overheating, both fans should be running.
If they
aren’t, your vehicle needs service.
How to Add‘Coolant to the Coolant Surge Tank
If you haven’t found a problem yet, but the coolant level isn’tvisible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze 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 “Engine Coolant’’ in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator hose, heater hoses, radiator,
water pump or somewhere else in the cooling system.

NOTICE:
I
In cold weather, water can freeze and crack the engine, radiat\
or, -
heater core and other parts. So use the recommended coolant. L

What to Use
Use a mixture of one-half clean water. (preferably distilled) and one-half
antifreeze that ,meets “GM Specification
.1825-M,” which won’t damage
aluminum parts. You can also use a recycled coolant conforming to GM
Specification 1825-M with a complete coolant .flush and refill. Use GM
.Engine Coolant Supplement. (‘sealer) with any. complete coofant change.
If you use this mixture, you don? need to add anything else.

To Add Coolant
If you need more coolant, add the proper mix at the coolant surce tank.
.~ . .
To Check or Add Coolant
When the engine is cold, remove the pressure cap from the surge tank,
use a flashlight as necessary to see into the tank. The coolant level should
be visible inside the tank about
2 112 inches (60 mm) below the base of
the fill neck.
If you need more coolant, add the proper mix.
SURGE TANK PRESSURE CAP
NOTICE:
Your surge tank cap is a 15 psi (1.05 kPa) pressure-type cap ana
must be tightly installed to prevent coolant loss and possible
engine damage
&om overheating. Be sure the arrows on the cap
line up with the overflow tube
on the surge tank filler neck.
I k
When you replace your surge tank pressure cap, an GM@ cap is
recommended.
