Downloaded from www.Manualslib.com manuals search engine Trailer Hauling
Since passenger cars are designed
and intended to be used primarily
as passenger conveyances, towing
a trailer will effect handling, dura­
bility
and economy. Maximum
safety and satisfaction depends
upon proper use of correct equip­
ment and avoiding overloads and
other abusive operation.
The maximum loaded trailer
weight which you can pull with
your car depends on what special
equipment has been installed on
your car. Chevrolet does not rec- ommend
towing any trailer
over
1,000 pounds gross trailer weight.
Information on trailer haul­
ing capabilities, special equipment
required, and optional equipment
offered by Chevrolet
is available
from your Chevrolet Dealer or by
writing Chevrolet Motor Division,
Detroit, Michigan 48202
(or in
Canada by writing to General
Motors of Canada Limited,
Owner
Relations Department, Oshawa,
Ontario LlJ 5Z6).
To assist in attaining good han­
dling of the car-trailer combination,
it
is important that the trailer
1-9
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 pla­
card,
is reduced by an amount
eq ual to the trailer tongue load on
the trailer hitch.

Four Way Hazard
Warning
Flasher
• Use the warning flasher to warn
other drivers any time your
ve­
hicle becomes a traffic hazard,
day or night.
• A void stopping on the roadway
if possible.
• Turn on the hazard warning
flasher by pushing
in on the but­
ton located on the column just
below the steering wheel. Flasher
can
be actuated with
engine ignition either
off or on.
• Turn signals do not work with
hazard flashers operating.
• If the brake pedal is depressed,
the lights will not flash but
re­
main continuously lit.
• To cancel the flasher, pull the
button out.
Freeing Car from Sand, etc.
If it becomes necessary to rock
the car to free it from sand, mud
or snow, move the selector lever
on automatic transmission models
from
"D" to "R" in a repeat pat­
tern while simultaneously applying
moderate pressure
to the accelera­
tor.
(On standard transmission
models, move gear shift lever from
second to reverse gear.) Do not
race engine. For best possible trac­
tion, avoid· spinning wheels when
3-1
trying to free the car. The use of
AC Liquid Tire Chain
is recom­
mended for temporary assistance
when traction
is lost on ice or
snow.
Towing
Proper lifting and towing equip­
ment
is necessary to prevent dam­
age to the vehicle during any tow­
ing operation. State (Provincial in
Canada) and local laws applicable
to vehicles in tow must be
fol­
lowed. Detailed towing instructions
are available at your Chevrolet
dealer. Your Vega may be towed on
all
four wheels, at speeds of less · than

Use of Tire Chains
Tire chains may be used on your
Vega if it
is equipped with the
standard wheel
(13" x 5"). If your
Vega
is equipped with 13" x 6"
wheels, it cannot be modified to
accept tire chains.

Trim Materials with
Solvent
Type Cleaner
Before attempting to remove
spots or stains from fabric, deter­
mine
as accurately as possible the
nature and age of the spot or stain.
Some spots or stains can be re­
moved satisfactorily with water or
mild soap solution (refer to ac­
companying
"Removal of Specific
Stains"). For best results, spots or
stains should be removed
as soon
as possible. Some types of stains
or soilage such
as lipstick, some
inks, certain types of grease 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.
G.M.
Spot Lifter (Solvent Type)
is excellent for spot cleaning stains
containing grease, oil or fats from
fabric type trim. Excess stain
should be gently scraped off trim
material with a clean DULL knife
or scraper.
USE VERY LITTLE
CLEANER, light pressure, and
clean cloths (preferably cheese
cloth). Cleaning action should be
from outside of stain FEATHER­
ING towards center of stain and
constantly changing· to a clean sec­
tion of cloth.
When stain is cleaned
from · fabric, immediately dry area
with an· air
hose, heat dryer or heat
l~mp to help prevent a cleaning
flng (use caution with heat dryer
or heat
lamp to prevent damage to
fabric material).
If a ring forms,
immediately repeat the
. cleaning
operation over a slightly larger
area with special emphasis on
FEATHERING towards center of
area.
If ring still persists, mark
off adjacent trim sections and clean

Carefully scrape off excess stain;
then use Spot Lifter (Solvent
Type) as previously described.
Shoe polish, wax crayons, tar and

will stain if allowed to
remain on trim; they should be
removed
as soon as possible-use
caution
as cleaner will dissolve
them and may cause them to bleed.

The factory installed tires on
your vehicle, shown in the Tire
Usage Chart, are engineered to pro­
vide a proper balance of these per­
formance characteristics for normal
vehicle operation:
• Endurance
• Handling
• Noise
• Ride
• Road Hazard Resistance
• Rolling Resistance
• Traction
• Tread Mileage
This section contains some tips
on how you can obtain maximum
benefit from these tires and your
investment in them.
Vehicle Loading
When inflated as recommended
on the tire pressure placard, located on
the left door of your vehicle,
the
tires originally installed will operate
satisfactorily at all normal highway
loads and speeds. Do not load your
vehicle beyond the capacity shown
on the tire placard. This represents
the design capacity of the vehicle,
not merely of the tires.
Station Wagon loads should
be
distributed as far forward as pos­
sible. Luggage racks do not in­
crease the maximum vehicle load
capacity specified on the tire pla­
card.
Inflation Pressure
Tire cold inflation pressures
listed on the tire placard provide
for the best combination of tire life,
riding comfort, and vehicle hand­
ling for normal driving conditions.
Use of the highest pressures shown
on the placard will result in
im­
proved fuel economy. For those
owners who prefer the utmost in

It is normal for tire pressures to
increase 4-8
PSI when the tires
become hot from driving. Do not
"bleed" (reduce tire inflation
pressures) after driving your
vehicle. Bleeding serves to in­
crease tire flexing and heat build­
up which can result in tire dam­
age and failure.
3. For sustained driving at turn­
pike speeds, cold inflation
pressures should be increased 4
PSI above the recommended
cold inflation pressures on the
tire placard up to a maximum of
32
PSI for load range Btires, 36
PSI for load range C, and 40 PSI
for load range D. Sustained
speeds above 75 mph are not
recommended when the 4
PSI
adjustment would require pres­
sures greater than the maximum
pressures above.
4. Always use a tire pressure gauge
(a pocket type gauge is recom­
mended) when checking
infla~
tion pressures. Underinflated
radial tires may have the same
appearance
as a properly inflated
radial tire.
Visual inspection of
tires for inflaton is totally inade­
quate especially in the case
of
radial tires. If inflation pressure
of an individual tire
is found to be
consistently low, have your
dealer find and correct the cause.
5. Be sure to re-install the tire in­
flation valve caps, if
so equipped,
to prevent dirt and moisture
from entering the valve core
which could cause air leakage.
Inspection and Rotation
Your tires perform different jobs
(front tires are involved with steer­
ing and rear tires normally with
propelling the vehicle) and can
wear differently depending on the
type of roads driven, individual

driving habits, etc. To obtain maxi­
mum tire life you should inspect
and rotate your tires regularly.
Many car
and tire dealers will per­
form a free tire inspection
and
assist you in identifying uneven
or abnormal tire wear which is
usually the result of incorrect infla­
tion pressure, lack
of regular rota­
tion, improper wheel alignment,
out-of-1?alance, or poor driving
habits.

and then at least at 15,000 mile in­
tervals thereafter or whenever un­
even tire wear is noticed.

See the Main~e­
nance Schedule folder for more m­
formation. Some ball-joints have
built-in wear indicators and some
movement in the joints
is normal.
Improper front -end alignment will
.
not cause vibration. Improper toe
alignment
may cause your. fro~t
tires to drag at an angle resultmg m
excessive wear. Improper camber
alignment may cause your front
tires to wear more
on one side than
on the other and can cause the
vehicle to
"pull" to the left or right.
Proper tire balancing provides
the best riding comfort and helps
to minimize tire tread wear.
Out-of­
balance tires can cause annoying
vehicle vibration and irregular tire
wear such
as cupping, fiat spots,
etc.

Downloaded from www.Manualslib.com manuals search engine Air Cleaner
Your car receives its power from
a mixture of gasoline and air. The
air
is taken in to the system through
the air cleaner
so it's important to
replace the air cleaner at required
intervals. A dirty air cleaner re­
duces engine efficiency.
Properly Tuned Engine
Overall tuning (a check on tim­
ing, spark plugs, emission control
devices, etc.) can improve your
car's gas mileage. You just can't
expect an
"out-of-tune" engine to
give you good gas mileage and
cleaner air.
Excess Weight
Fuel economy is related to the
work the engine must do. The
heavier the load, the more power it
takes. Keep excess weight to a
minimum by removing any per­
sonal effects or luggage from the
car or trunk when they are not
needed.
Tire Inflation
Underinfiation not only causes
needless wear of the tires, but can
also waste gasoline. It's a good
idea to check tire pressures
regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" can
have the effect
of dragging your
front tires sideways and may cause
premature tire wear.
It takes power
to carry this extra load and that
takes gas from your tank.
Catalytic Converter
The catalytic converter IS an
emission control device added to
5-22
the exhaust system to reduce hy­
drocarbon and carbon monoxide
pollutants from the exhaust gas
stream.
The converter contains
beads which are coated with a cata­
lytic material containing platinum
and palladium.
Use of the catalytic converter
has the advantage of allowing the
engine to be re-tuned for improved
fuel economy and driveability.
The catalytic converter requires
the use
of unleaded fuel only.
Unleaded gasoline is used to re­
duce combustion chamber deposits,
corrosion and
to prevent lead con­
tamination of the catalyst that
would render it ineffective.
The use
of leaded fuel will cause the cata­
lytic converter to
become ineffec­
tive as an emission control device.
