+' LOWER: This setting directs most of the air
through the lower ducts to the floor area of the vehicle with some of the air also directed toward the windshield
and side window vents.
+# DEFOG: This setting divides the air between the
windshield and lower outlets with a small amount directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
DEFROST Use this setting to quickly remove fog
or frost from the windshield. This setting directs most of
the airflow to the windshield with
a small amount
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning and the rear window defogger operation.
FRESH AIR: Press this button and it will bring
outside air into your vehicle. The light on the button will
come on when operating. Use this setting while trying to
defrost or defog windows to help clear moisture.
RECIRCULATE: Press this button to limit the
amount of fresh air entering your vehicle by
recirculating most of the
air inside your vehicle. The
light on the button will come on when operating. This
setting is helpful when you are trying to cool the air
quickly or to limit odors entering your vehicle.
RECIRCULATE cannot be used while in the DEFROST
or
DEFOG modes.
e A/C: This button turns the air conditioning
compressor
off or on under most conditions. The light
on the A/C button comes on when the compressor is
operating. The air conditioning does not operate at
temperatures below approximately
35 OF to 40°F (2" C
to 4°C). The air conditioning cools and dehumidifies the
air coming into the vehicle. The air conditioning cannot
be turned
off in DEFROST as it helps to remove
moisture from the vehicle. It also helps to keep the
windows clear.
The air conditioning may be forced
off at high engine
speeds
or high engine oil or coolant temperatures.

Handle discs carefully. Store them in their original cases
or other protective cases and away from direct sunlight
and dust.
If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and clean it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick up discs by grasping the outer edges or the
edge of the hole and the outer edge.

Reduce your speed according to your speedometer, not
to your sense

at higher speeds, you may tend to think you are going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive in.
Is your vehicle ready for a long trip?
If you keep it
serviced and maintained, it’s ready
to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts in
GM
dealerships all across North America. They’ll be ready
and willing to help if you need it. Here are some things you can check before a
trip:

Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a short’
time to avoid a major storm system?

You will find an engine coolant temperature gage on the
instrument cluster and a COOLANT OVER TEMP
message on the Driver Information Center
(DIC).
Overheated Engine Protection
Operating Mode
Should a low coolant condition exist and the messages
COOLANT OVERTEMP and REDUCED ENGINE
POWER are displayed, along with the Check Engine
light, an overheat protection mode which alternates
firing groups of four cylinders helps prevent engine
damage. In this mode, you will notice a loss in power
and engine performance. 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).
1 NOTICE:
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss, change the oil and reset
the oil life monitor. See “Engine Oil, When to
Change” in the Index.

Downloaded from www.Manualslib.com manuals search engine 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 mixture will. Your vehicle’s coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
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 mixture of clean water and
DEX-COOL@ coolant.
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 on hot
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.
