I
A GA ‘TION:
If you have a rear-most window open and you
pull a trailer with your vehicle, carbon monoxide
(CO) could come into your vehicle. You can’t see
or smell
CO. It can cause unconsciousness or
death. (See “Engine Exhaust” in the Index.) To
maximize your safety when towing
a trailer:
0 Have your exhaust system inspected for
leaks, and make necessary repairs before
starting on your trip.
Keep the rear-most windows closed.
0 If exhaust does come into your vehicle
through a window in the rear or another
opening, drive with your front, main
heating or cooling system on and with the
fan
on any speed. This will bring fresh,
outside air into your vehicle.
Do not use
MAX AfC because it only recirculates the
air inside your vehicle. (See “Comfort
Controls” in the Index.) Towing a
trailer requires
a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the
feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you
are driving is now a
good deal longer and not nearly as
responsive as your vehicle is by itself.
Before
you start, check the trailer hitch and platform
(and attachments), safety chains, electrical connector,
lamps, tires and mirror adjustment.
If the trailer has
electric brakes, start your vehicle and trailer moving and
then apply the trailer brake controller by hand to be sure
the brakes are working. This lets you check your
electrical connection at the same time.
During your trip, check occasionally to be sure that the
load
is secure, and that the lamps and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.

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.
0 Tow a trailer. See “Driving on Grades” in the Index.
If you get the overheat warning with no sign of steam,
try this for a minute
or so:
1. Turn off your air conditioner.
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
-- DRIVE (D) or THIRD (3) for
automatic transmissions. 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 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 ofSthe
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.

Downloaded from www.Manualslib.com manuals search engine Checking Brake Fluid What to Add
You can check the brake
fluid without taking off
the cap.
Just look at the brake
fluid reservoir. The fluid level
should be above
MIN. If it isn’t, have your brake system
checked to
see if there is a leak.
After work
is done on the brake hydraulic system,
make sure the level is above the MIN but
not over
the MAX mark or the top of the window
on the side
of the reservoir. When
you do
need brake fluid, use only DOT-3
brake fluid
-- such as Delco Supreme 1 l@ (GM Part
No. 12377967). Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
A CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.

Downloaded from www.Manualslib.com manuals search engine NOTICE: (Continued)
If you do find traction devices that will fit, install
them on the rear tires.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE Class
“S” type chains that are the proper
size for your tires. Install them on the drive axle
tires (four-wheel-drive vehicles can use chains on
both axles) and tighten them as tightly as possible
with the ends securely fastened. Drive slowly and
follow the chain manufacturer’s instructions.
If
you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues,
slow down until it
stops. Driving too fast or
spinning the wheels with chains on will damage
your vehicle.
Appearance Care
Remember, cleaning products can be hazardous. Some
are toxic. Others can burst into flame
if you strike a
match or get them on a hot part of the vehicle. Some are
dangerous
if you breathe their fumes in a closed space.
When
you use anything from a container to clean your
vehicle, be sure
to follow the manufacturer’s warnings
and instructions. And always open your doors or
windows when you’re cleaning
the inside.
Never use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
0 Turpentine
Lacquer Thinner
Nail Polish Remover
They can
all be hazardous -- some more than
others
-- and they can all damage your vehicle, too.

Downloaded from www.Manualslib.com manuals search engine Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal. tobacco smoke and dust films on
interior glass.
Don’t use abrasive cleaners on glass, because they may
cause scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped off later.
If abrasive cleaners are used on the inside
of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across
the defogger grid.
Cleaning the Outside of the Windshield,
Backglass and Wiper Blades
If the windshield is not clear after using the windshield
washer, or
if the wiper blade chatters when running,
wax, sap
or other material may be on the blade
or windshield. Clean the
outside of the windshield with GM
Windshield Cleaner, Bon Ami’ Powder (non-scratching
glass cleaning powder), GM Part
No. 105001 1. The
windshield
is clean if beads do not form when you rinse
it with water.
Grime from the windshield will stick to
the wiper blades
and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield
washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every
six months. During
very cold, damp weather
more frequent application may be required. (See
“Recommended Fluids and Lubricants” in the Index.)

Downloaded from www.Manualslib.com manuals search engine Headlamps Fuses and Circuit Breakers
The headlamp wiring is protected by an internal
circuit breaker. An electrical overload will cause the
lamps to go
on and off, or in some cases to remain off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools. If
the overload is caused by some electrical problem, be
sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is
too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away. The
wiring circuits in your vehicle are protected from
short circuits by a combination
of fuses and circuit
breakers. This greatly reduces the chance of fires
caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band
is broken or melted, replace the fuse. Be sure you
replace
a bad fuse with a new one of the identical size
and rating.
If
you ever have a problem on the road and don’t have
a spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without -- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as
you can.
