The 3-speed manual transmis­
sion shift positions follow the
stan­
dard pattern shown on the illustra­
tion. The 4-speed transmission shift
lever, extending from the floor,has
its special shift pattern diagram
lo­
cated on the knob or floor plate.
Depress the clutch pedal fully
be­
fore attempting to shift to a differ­
ent gear, then release the pedal to
move in that gear. Shifting into 2nd
and 3rd gear
as soon as possible
will add appreciably to your fuel
economy.
Both transmissions, being fully
synchronized, may be downshifted
into 1st gear at any speed below
20
m.p.h. Shift into Reverse gear only
after the car has stopped. Always depress
and release the clutch pedal
fully when shifting.
On Four-Speed
transmission the shift linkage may
be adjusted to allow
"short stroke"
shift lever operation. See your
Chevrolet Dealer.
Also, shift into
"Reverse" before
shutting
off engine. This will permit
the ignition key to be turned to the
"Lock" position.
REMINDER: Before descending a
steep or long grade, down a moun­
tain or hillside, reduce speed and
shift into a lower gear (for either
automatic or manual transmission
cars).
Use the brakes sparingly to
prevent them from overheating and
thus reducing brake effectiveness.

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.

Downloaded from www.Manualslib.com manuals search engine EVAPORATION CONTROL SYSTEM
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.
