Downloaded from www.Manualslib.com manuals search engine NOTICE:
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 weather, the kind of oil you have, and some other things.
Instead
of trying to list everything here, we ask that you contact a GM
dealer in the area where you’ll be parking your vehicle. The dealer can give
you the best advice for that particular area.
Automatic Transmission
.. . ...
There are several
different positions for
your shift lever.
P (Park) - This locks your rear wheels. It’s the best position to use
when you start your engine because your vehicle can’t move easily.

Standard Cluster Digital Cluster
If you have a standard cluster, this gage shows the engine coolant
temperature.
If the gage pointer moves into the red area, your engine is too
hot!
It means that your engine coolant has overheated.
If you have been
operating your vehicle under normal driving conditions, you should pull
off
the road, stop your vehicle and turn off the engine as soon as possible.
If you have a digital cluster, a box around the temperature symbol will also
flash and a chime will sound when your engine is too hot.
Hot Coolant Can Burn you Badly! In Problems On The Road, this manual
explains what to do. See “Engine Overheating
” in the Index.

Downloaded from www.Manualslib.com manuals search engine DEFROST This setting operates the defroster. Most of the air comes out
near
the windshield, with some going to the floor vents and side window
defrost vents.
Use this when you get fog or ice on the windshield.
HTR (Heater): Most of the air comes out near the floor. The rest comes out
from the defroster vents under the windshield and at
your front side
windows. This is best for cold weather.
VENT The air comes out at the vents on your instrument panel and at your
front side windows.
BI-LEV A/C: With this, outside air comes in through the heater floor vent
and the instrument panel vents. This setting is useful
in cool weather with
bright sunlight.
NORM A/C: This setting cools the outside air. If you first use MAX, use
NORM as soon as the vehicle has cooled down, so outside air will be going
through your vehicle.
MAX A/C: This cools the air the fastest. Move the other lever all the way to
Cold.
MAX lets in only a little air from the outside. You can use MAX at
first when it’s really hot outside and you need to cool off quickly.
NOTICE:
If vehicle is parked with function lever in MAX A/C position
and on an incline with the right side lower than the left, t\
hen water may leak into the passenger compartment in an unusually
heavy rain.
J
OFF: The blower is off, but air still will come from outlets at the front of
your vehicle. The system
will try to keep the air at the chosen temperature.
Engine Coolant Heater (Engine Block Heater)
If you use the optional engine coolant heater before starting your engine,
your heating system
will produce warmer air faster, to heat the passenger
compartment
in cold weather. See “Engine Coolant Heater” in the Index.
Rear Window Defogger
If your vehicle has this option the rear window will have lines running
across the glass. These lines heat your window.
For best results, clear the window
of as much snow or ice as possible first.

Downloaded from www.Manualslib.com manuals search engine Winter Driving
Here are some tips for winter driving:
Have your vehicle in good shape for winter. Be sure your engine
coolant mix is correct.
You may want to put winter emergency supplies in your vehicle.
Include
an ice scraper, a small brush or broom, a supply of windshield
washer fluid,
a rag, some winter outer clothing, a small shovel, a flashlight,
a red cloth, and a couple
of reflective warning triangles. And, if you will be
driving under severe conditions, include a small bag of sand,
a piece of old
carpet
or a couple of burlap bags to help provide traction. Be sure you
properly secure these items in your vehicle.
Driving on Snow or /ce
Most of the time, those places where your tires meet the road prob\
ably have
good traction.
However, if there
is snow or ice between your tires and the road, you can
have a very slippery situation. You’ll have a
lot less traction or “grip” and
will need to be very careful.

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 overheat warning with 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
3. If you’re in a traffic jam, shift to “N” (Neutral).
window as
necessary.
If
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.
If
the warning continues, pull over, stop, and park your vehicle right away.
If there’s still no sign of steam, push
the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine speed back to
normal idle speed after two
or three minutes. Now 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.
When
you decide it’s
safe to
lift the hood,
here’s what you’ll see:
A. Coolant recovery
B. Radiator pressure
C. Engine fan tank
cap
If the
coolant inside the coolant recovery tank is boiling, don’t do anything
else until
it cools down.

The coolant level should be at or above the ADD mark. 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.
NOTICE:
Engine damage from running your engine without coolant isn't
covered by your warranty.
If there seems to be no leak, start the engine again. See if the fan speed
increases when idle speed is doubled
by pushing the accelerator pedal down.
If
it doesn't, your vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant Recovery Tank
If you haven't found a problem yet, but the coolant level isn't at or above
the
ADD mark, add a 50/50 mixture of clean water (preferably distilled)
and a proper antifreeze at the coolant recovery tank. (See "Engine Coolant"
in the Index for more information about the proper coolant mix.)
