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.
• Avoid stopping on the roadway
if possible.
• Turn on the hazard warning
flasher, with engine ignition off
or on, by pushing in on the but­
ton located just below the steer­
ing wheel.
• If the brake pedal is depressed,
the lights will not flash
but will
glow continuously instead.
• To cancel the flasher, pull the
button outward.
"Rocking" Car
If it becomes necessary to rock
the car to free it from sand, mud or
snow, move the selector lever
from
"D" to "R" in a repeat pattern
while simultaneously applying
moderate pressure to the accelera­
tor. Do not race engine. A void
spinning wheels when trying to free
car.
Towing
Proper lifting or towing equip­
ment
is necessary to prevent dam­
age to the vehicle during any tow­
ing operation. Detailed towing in­
formation is available at your
dealer and has been provided to
tow truck operators responsible for
movement of disabled or locked
ve­
hicles. State and local laws appli­
cable to vehicles in tow must also
be followed.
Your Camaro may be towed on
all four wheels, at speeds of less
than 35 MPH, for distances up to
38
50 miles, provided driveIine, axle
and transmission are otherwise nor­
mally operable.
For such towing,
parking brake must be released,
and transmission must be in neu­
tral (ignition lock turned to
OFF
position). Attachments must be to
main structural members of the car,
not to bumpers or bracketing,
Safety chains or cables should be
used. Remember that power steer­
ing assist will not be available when
engine
is inoperative.
Emergency Starting
• Never tow the car to start
because the surge forward when
the engine starts could cause a
collision with the tow vehicle.
• Engines in vehicles with auto­
matic transmissions cannot be
started by pushing the car.

AIR POLLUTION CONTROL SYSTEMS
AND THE SERVICE THEY REQUIRE
Source of Emissions
During the combustion process in an automotive
engine, some of the fuel (hydrocarbons) fails to
bum
completely and is discharged into the engine crank­
case or exhaust system. Additional hydrocarbons are
emitted into the atmosphere through evaporation of
gasoline vapors from the fuel tank and carburetor.
Of the total hydrocarbons coming from uncontrolled
automobiles, about
20% are emitted from the crank­
case,
20% from the fuel system and 60% from the
engine exhaust.
In addition to hydrocarbons, carbon monoxide
and oxides of nitrogen are also formed during the
41
combustion process. These are also discharged into
the exhaust system.
What General Motors Has Done
Since research on the control of vehicle emissions
first began some
20 years ago, General Motors has
developed a number of control systems which are
highly effective in reducing undesirable emissions.
(These systems are discussed in some detail in the
following pages of this section). The progress made
is evidenced by a reduction in hydrocarbon emissions
of
80% since 1960. Control of hydrocarbon emis­
sions
is important since, when subjected to sunlight

Downloaded from www.Manualslib.com manuals search engine under the proper conditions, they react with other
gases to form photochemical smog, which
is so prev­
alent in Los Angeles.
In addition, carbon monoxide emissions have been
reduced by about 65 percent compared with 1960
model cars without controls. Although carbon mon­
oxide does not enter into the complex photochemical
smog reaction, it
is toxic at high concentrations and
thus, has been controlled to prevent high atmospheric
concentrations.
Recent Developments
Another important advancement in air pollution
control has been the removal of lead from gasoline.
(Certain lead compounds have been used for many
years
as additives to increase octane ratings.) All
1971 General Motors cars including your Camaro
are designed
to operate on unleaded or low-lead
(zero to
0.5 grams per gallon) gasolines. However,
any gasoline with
91 Research Octane Number or
42
higher will satisfy your engine's octane requirements.
Use of unleaded or low-lead gasoline will keep your
engine running efficiently and play an important part
in reducing exhaust emissions of hydrocarbons and
particulates.
Your Role In Controlling Air Pollution
1. Use Unleaded or Low-Lead Fuels-To obtain
maximum results
In the reduction of automotive
emissions, use an unleaded gasoline.
If such gaso­
line
is not available, you may use a leaded regu­
lar grade gasoline.
2. Have The Air Pollution Control Systems on Your
Car Serviced Regularly -
The following pages of
this section describe the emission control systems
on Chevrolet vehicles and provide information
on their proper maintenance. By following these
recommended maintenance services you will help
assure cleaner air and provide a better running,
longer lasting engine and greater all around satis­
faction, economy and performance.

pey
VALVE
OPERATION: All General Motors gasoline engine
powered vehicles are equipped with Positive
Crank­
case Ventilation-a system which permits no crank­
case emissions to be discharged into the atmosphere.
To function properly, the system depends on the
43
PCV Valve which returns blow-by gases to the com­
bustion chamber where they are burned.
MAINTENANCE: This valve must be clean in
order to maintain efficient engine operation.
An
inspection of the ventilation filter should be
made at the first oil change
(4 months or 6,000
miles, whichever occurs first). At each subse­
quent oil change, the ventilation filter
should
be inspected and replaced if necessary. Re­
place filter at least every 24,000 miles. Under
normal driving conditions, the PCV Valve should
be replaced every 24 months or 24,000 miles,
whichever occurs first, and
all hoses and fit·
tings
should be inspected and cleaned or re­
placed, as necessary. Replace the PCV Valve
and inspect related parts every 12 months or
12,000 miles when the vehicle is used in a ser­
vice requiring more frequent engine oil change
as covered on page 53.
NOTE: Emission control systems in this section are Illustrated on V-8 engines; systems on 4 and 6 cylinder engines are similar.

as well as full power and performance,
depend
upon engine idle speed, ignition tim­
ing,
and dwell being set according to the spec­
ifications
shown on a label under the hood.
These adjustments should be checked at the

(4 months or 6,000 miles,
whichever comes first). Subsequent checks
should be made at
12 month or 12,000 mile
intervals, whichever comes first. These adjust­
ments are also included
as part of the quality

.... ~!~:~~A:~~~~I:E ~ TREATED EXHAUST ~(TOUMOS'HERE THMOUGHHHAlIST'II'E)
OPERATION: The Air Injection Reactor system,
(used on vehicles not equipped with
CCS) is de­
signed to reduce air pollution by oxidizing (burning)
the hydrocarbons and carbon monoxide after they
45
leave the combustion chamber. A positive displace­
ment air pump, driven by the engine, compresses
filtered air which
is injected at the exhaust port of
each cylinder. This air mixes with the exhaust gases
and promotes further oxidation of both hydro­
carbons and carbon monoxide. The
AIR system also
includes a specially calibrated carburetor and dis­
tributor.
MAINTENANCE: Complete effectiveness of this
system
is dependent on the engine idle speed,
ignition timing and
dwell being set according
to specifications as indicated on a label under
the hood. These adjustments should be
checked at the first oil change (4 months or
6,000 miles, whichever comes first). Subse­
quent checks should be made at 12 months or
12,000 mile intervals, whichever comes first.
These adjustments are
also included as part of
the
quality tune-up recommended at the same
intervals. In addition, all hoses and fittings
should be inspected to make sure they are
properly connected, and the drive belt in­
spected for wear
and tension on the 12 month
or
12,000 mile schedule.

LIQUID/VAPOR SEPARATOR
OPERATION: All General Motors passenger cars
and light trucks are equipped with an Evaporation
Control
System. This system is designed to minimize
the escape of fuel vapors to the atmosphere. Included
in the system are a special fuel tank, liquid-vapor
separator, carbon canister, canister purge hoses, and
carburetor modifications. Fuel vapors which would
otherwise escape to the atmosphere are directed into
the carbon canister. The carbon adsorbs the vapors
and stores them. The vapor
is removed from the
46
canister during periods of engine operation as mani­
fold vacuum draws the vapors into the engine and
burns them.

Care and Cleaning
of Interior Soft Trim
Dust and loose dirt that accumu­
late on interior fabric trim should
be removed frequently with a
vac­
uum 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
re­
move spots or stains from uphol­
stery, determine as accurately as
possible the nature and age of the
spot
or stain. Some spots or stains
can be removed satisfactorily with
water
or mild soap solution (refer
to accompanying
"Removal of Spe­
cific 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, certain types of grease,
mustard, etc., are extremely
diffi­
cult and, in some cases, impossible
to completely remove. When
clean­
ing 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
care­
less cleaning.
47
CAUTION: When cleaning Interior soft trim such as upholstery or carpeting, do
not use volatile cleaning solvents such
as: acetone, lacquer thinners, carbon tet­
rachloride, enamel reducers, nail polish
removers; or such cleaning materials .s
laundry soaps, bleaches or reducing
agents (except as noted in the Instruc­
tions on stain removal). Never use gaso­
line or naphtha lor any cleaning purpose.
These
materl./s may be toxic or flam­
mable, or may cause damage to Interior
trim.
