To assist in attaining good han­
dling of the car-trailer combina­
tion, it
is important that the trailer
tongue load be maintained at ap­
proximately
10% of the loaded
trailer weight. Tongue loads can be
adjusted by proper distribution of
the load in the trailer, and can be
checked by weighing separately the
loaded trailer and then the tongue.
When towing trailers, tires
should be inflated to the highest inflation
pressures shown on the
placard affixed to the left front
door . The allowable passenger and
cargo load, also shown on the same
placard ,
is reduced by an amount
equal to
the trailer tongue load on
the trailer hitch.
Maintenance
More frequent vehicle mainte­
nance
is required when using your
car to pull a trailer. Change the:
• Automatic transmission fluid
each
12 ,000 miles ,
• Rear axle fluid each 12,000
miles,
• Engine oil each 60 days or 3,000
12
miles , whichever occurs first.
• Positive crankcase ventilation
valve each 12 months or
12,000
miles, whichever occurs first.
Break-in Schedule
In addition to the new ca r
break-in instructions in this man­
ual, it
is recommended that your
new Monte Carlo be operated for
500 miles before trailer towing. If
it is necessary to tow during this
period , avoid speeds over
50 MPH
and full throttle starts. The same
precautions should be observed
whenever a new engine, transmis­
sion or axle
is installed in your car.

Engine Exhaust Gas Caution (Carbon Monoxide)
Allold inhaling exhaust gases because
they contain carbon monoxide, which by
Itsell is colorless and odorless. Carbon
monoxide is a dangerous gas that can cause unconsciousness and is potentially
lethal.
II at any time you suspect that exhaust fumes are entering the passenger com­partment, have the cause determined and corrected as soon as possible. II you must
drive under these conditions, drive only
with
all windows fully open.
The best protection against carbon
mon­oxide entry into the car body is a properly
maintained exhaust system, car body and body ventilation system. It is recom­mended that the exhaust system and body
be inspected by a competent mechanic:
• Each time the IIehicie is raised for oil change. > •
Wheneller a change
is noticed In the
sound of the exhaust system.
• Wheneller the exhaust system, under­
body or rear of the vehicle is damaged.
See your Maintenance Schedule folder
for inspection procedure.
To allow proper operation of the car's
IIentilation system, keep front ventilation
inlet
grille clear of snow, leaves or other obstruction at all times.
SITTING IN A PARKED CAR WITH
ENGINE RUNNING FOR AN EXTENDED PERIOD IS NOT RECOMMENDED.
Do
not run engine in confined areas such as garages any more than needed to mOlle IIehicle In or out of area. When IIe­hlcle is stopped In an UNCONFINED area with the engine running for any more than a short period, adJust heating or cooling system to force outside air Into car as follows:

1. On cars not equipped with air condi­
tioning, set fan to medium or high
speed and upper control leller to any
position except OFF.
2. On cars equipped with manual air conditioning, set fan to medium or high speed, upper control lever to any
position except OFF, and lower con­trol lever to any position except ex­treme left COLD.
The trunk lid should be closed while
drilling to help prellent inadllertently draw­Ing exhaust gases Into the car. If Is unwise to drive at high speeds for long durations
with the trunk lid open. Howeller, If lor some reason the trunk must remain open lor a period while mOiling, or electrical wiring or other cable connections to a trailer must pass through the seal between
trunk lid and body, the lol/owlng precau­
tions should be observed:
• Close all windows.
• Ad/ust heating or cooling system to
force outside air into car as described In items 1 and 2 abolle but with Ian set at high speed.
• On cars equipped with outside aIr IIents In or under Instrument panel, open IIents lully.

Pressing the control will send a
measured amount of water or other
cleaning agent onto the windshield
and will also cause the wiper lever
to move thus starting the wiper
motor. The wiper will continue to
operate until manually turned off

weather is bad .
• Use a fluid such as GM OPTI­
KLEEN to prevent freezing
damage, and to provide better
cleaning.
• Do not use radiator anti-freeze
in windshield washer; it could
cause paint damage.

Care and Cleaning
of Interior Soft Trim
Dust and loose dirt that accum­
ulate on interior fabric trim should
be removed frequently with a
vacuum cleaner, whisk broom or
soft brush. Vinyl
or leather trim
should be wiped clean with a
damp cloth. Normal cleanable trim
soilage, spots or stains can be
cleaned with the proper use of trim
cleaners available through General
Motors dealers or other reputable
supply outlets. Before attempting
to remove spots or stains from
up­
holstery, determine as accurately
as possible the nature and age of
the spot or stain.
Some spots or
stains can be removed
satisfactor ­
ily with water or mild soap solu­
tion (refer to accompanying "Re­
moval of Specific Stains"). For
best results, spots or stains should
be removed
as soon as possible.
Some types of stains or soilage
such
as lipsticks, some inks, cer­
tain types of grease, mustard, etc.,
are extremely difficult and, in some
cases, impossible to completely
re­
move. When cleaning this type of
stain or soilage, care must be taken
not to enlarge the soiled area.
It is
sometimes more desirable to have
a small stain than an enlarged stain
as a result of careless cleaning.

Cleaning
Fluid
This type of cleaner should be
used for cleaning stains containing
grease, oil or fats. Excess stain
should be gently scraped off with
a clean dull knife or scraper.
Use
very little cleaner, light pressure,
and clean cloths (preferably cheese
cloth). Cleaning action with
cloth should be from outside of
stain towards center and constantly
changing to a clean section of
cloth. When stain
is cleaned from
fabric, immediately wipe
area
briskly with a clean absorbent
towel or cheese cloth to help dry
area and prevent a cleaning ring.
If ring forms, immediately clean
entire area or panel section of the
trim assembly.
NOTE: Sometimes a difficult spot
may require a second application
of cleaning fluid followed immedi­
ately by a soft brush to completely
remove the spot.
Cleaning Fabrics with
Detergent Foam Cleaners
This type of cleaner is excellent
for cleaning general soilage from
fabrics and for cleaning a panel
section where a minor cleaning
ring may be left from spot clean­
ing. Vacuum area to remove ex­
cess loose dirt. Always clean at
least a full trim panel or section
of trim. Mask adjacent trim along
stitch or weld lines. Mix detergent
type foam cleaners in strict ac­
cordance with directions on label
of container.
Use foam only on a
clean sponge or soft bristle brush
-Do not wet fabric excessively or
47
rub harshly with brush. Wipe clean
with a slightly damp absorbent
towel or cloth. Immediately after
cleaning fabric, dry fabric with a
dry towel or hair dryer. Rewipe
fabric with dry absorbent towel or
cloth to restore luster of the trim
and to eliminate any dried residue.
Seat Belt Care
• Clean only with mild soap solu­
tion and lukewarm water.
• Do not bleach or dye belts since
this may severely weaken belts.
Removal of Specific Stains
Candy-Chocolate, use cloth soak­
ed in lukewarm water; other than
chocolate, use very hot water. Dry.
If necessary, clean lightly with
fabric cleaning fluid.
Chewing Gum-Harden gum with
ice cube and scrape off with dull
knife. Moisten with fabric cleaning
fluid and scrape again,
