Engine Exhaust Gas Caution (Carbon Monoxide)
Avoid inhaling exhaust gases because
they contain carbon monoxide, which by
itsel# is colorless and odorless. Carbon
monoxide
Is a dangerous gas that can
cause unconsciousness and is potentially
lethal.
1# at any time you suspect that exhaust
fumes
are entering the passenger com­
partment, have the cause determined and
corrected
as soon as possible. 1# 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 engine exhaust sys­
tem, car body and body ventilation system.
It is recommended that the exhaust sys­
tem and body Is Inspected by a competent
mechanic:
• Each time the vehicle Is raised for 011
change.
• Whenever a change Is noticed In the
sound
of the exhaust system.
• Whenever 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
ventilation 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 move vehicle in or out of area. When
vehicle 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:
12
1. On cars not equipped with air condi­
tioning, set fan to medium or high
speed and upper control lever to any
position except OFF.
2. On cars equipped with air condition­Ing, set tan to medium or high speed
and upper control lever
to any position except OFF or MAX.
The trunk lid should be closed while
driving
to help prevent inadvertently
drawing exhaust gases into the
car. It Is
unwise to drive at high speeds tor long
durations with the trunk
lid open. How­
ever, if for some reason the trunk must
remain open
tor a period while moving,
or electrical wiring or other cable con­
nections to a trailer must pass through
the seal between trunk
lid and body, the
tollowing precautions should be observed:
• Close all windows.
• Adjust heating or cooling system to
force outside air into car as described
in items 1 and 2 above
but with tan set
at high speed.
• On cars equipped with outside air vents
in or under Instrument panel, open
vents tUlly.

ward to signal a right turn and
downward
to signal a left turn.
Lamps on the front and rear of the
car transmit this signal to other
motorists and pedestrians. The
ig­
nition switch must be in the "ON"
position in order for the turn sig­
nals to be operational. This feature
prevents battery drain
if the lever
is left in an "ON" position when
your car
is not in use.
In a normal turning situation
such
as turning a corner, the turn
signal
is cancelled automatically
after the turn
is completed. How­
ever, in some driving maneuvers
such as changing lanes
on an ex­
pressway, the steering wheel
is not
turned back sufficiently after com­
pleting the turn to automatically
cancel the turn signal. For con­
venience in such maneuvers, the
driver can flash the
tum signals by moving
the turn signal lever part
way (to the first stop) and holding
it there. The lever returns to the
neutral
or cancelled position when
the driver releases his hold on the
lever.
A green light on the instrument
cluster flashes to indicate proper
operation of the front and rear turn
signal lamps.
If the indicator lamp
18
remains on and does not flash,
check for a defective lamp bulb.
If
the indicator fails to light when the
lever
is moved, check the fuse and
indicator bulb.
Power Steering
If the steering system power as­
sist fails due to some malfunction,
or because the engine has stalled,
the car can still be steered.
How­
ever, much greater effort is re­
quired, particularly in sharp turns.
Holding Car on an Upgrade
When stopped on an upgrade,
maintain your position by applying
the brakes. Never hold the car in
place
by accelerating engine with
transmission in gear. This could
cause damage by overheating the
transmission (automatic) or clutch
(manual).

Downloaded from www.Manualslib.com manuals search engine Parking Your Car
Always engage the parking brake
and place the automatic transmis­
sion selector lever in
"Park" posi­
tion when leaving your
car unat­
tended. Also with automatic trans­
missions, never park for prolonged
periods with engine idling and
transmission in gear, especially if
your car
is equipped with air con­
ditioning. This practice
is detri­
mental to the transmission, due to
overheating.
Horn
The horn on your Camaro is
actuated by firmly pressing on the
horn button in the center of the
steering wheel.
Tilt Steering Wheel
The optional tilt steering wheel
can be tilted up above normal posi­
tion to provide additional room for
entrance and exit as well as selected
driving positions below normal
height. This permits individual
se­
lection of the most natural position
for all driving conditions.
On long
trips the steering wheel position can
be changed to minimize tension and
fatigue.
The
tilt mechanism is operated
by lifting up on the small control
As a good motorist, use of the
horn should be kept at a minimum.
However, acquaint yourself as soon
as possible with this function of lever
on the left side of the steering
column just below the directional
signal, moving the steering wheel to
the selected position, and releasing
the lever.

The red light will go on when
the ignition key
is in the "on" posi­
tion, but before the engine
is
started. After the engine starts, the
light should go out and remain out.
If the light remains on when engine
is running, have your Authorized
Chevrolet Dealer locate and correct
the trouble as soon
as possible.
Engine Temperature
Indicator Light
This indicator light is provided
in the instrument cluster to quickly
warn of an overheated engine. With
,the ignition switch in the START
position, the red
TEMP indicator
will light to let you know that it
is
operating properly.
When the engine
is started, the
red light will go out immediately.
It will light up at no other time
unless for some reason the engine reaches
a dangerously high oper­
ating temperature.
If the red light
should come on, the engine must be
stopped until the cause of the over­
heating
is corrected. Glance at in­
strument cluster frequently
as you
drive to see if this light
is on.
Brake System Warning
Light
The service brake system is de­
signed
so that half of the brake sys­
tem will provide some braking ac­
tion in the event of a hydraulic leak
in the other half of the system.
If
the warning light located at lower
left of instrument cluster (speed­
ometer face), glows continuously
when the ignition
is on and after
the brakes have been firmly applied
it may indicate that there
is a mal­
function in one half of the brake
hydraulic system.
On cars equipped
with front drum brakes, the light
24
will go out when foot is removed
from brake pedal.
• As a check on bulb condition
the light should glow with the
parking brake applied and the
ignition on. (Light
is also a re­
minder to release parking brake.)
• Have system repaired if light
does not come
on during check.
• This warning light is. not a' sub­
stitute for the visual check of
brake fluid level required
as part
of normal maintenance.
If the light glows red:
• The parking brake control is not
fully released or,
• The service brake system is par­
tially inoperative.
What to do:
1. Check that the parking brake is
released. If it is ...
2. Pull off the road and stop, care­

grilles, through the car and out the
rear air exhaust valves.
Basic Operating Tips:
• Always keep front inlet grille
clear of obstructions (leaves,
ice, snow, etc.).
• When heating or air condition­
ing
is desired, best comfort is at­
tained by driving with all the
windows closed.
The following sections of this
manual provide additional operat­
ing tips for obtaining maximum
heating and cooling comfort.

Air Vents
The air vents in each kick panel
admit air from the vent grille just
ahead of the windshield. Control
knobs open and close the vents.
The amount of air entering the
car through this system
is depend­
ent upon vehicle speed.
Four Season Air Conditioning
equipped cars have no kick panel
vents since the vents are a part of
the air conditioning system.

Downloaded from www.Manualslib.com manuals search engine • Keep all windows and vents
closed to reduce dust, road and
wind noise and uncomfortable
drafts.
• For most satisfactory heater op­
eration and air circulation , oper­
ate fan
on low or medium speeds
for normal operation and high
speed for quick warm-up and
during extremely low tempera­
tures.
• For adequate rear seat heating,
the area beneath the front seat
must not be blocked by carpet­
ing, rags, paper or other mate­
rial and fan should operate on
high blower.
• For additional summer ventila­
tion move the
AIR lever to mid­
position and the
DEFROSTER
lever to DEF. If greater air­
flow is desired, move the FAN
lever down to operate the three­
speed blower .
Rear Window Defroster
To insure clear vision through
the rear window during inclement
weather, the Rear Window De­
froster has become established as a
popular accessory . This unit draws in
air from the passenger compart­
ment and directs it against the back
window to remove frost or mois­
ture . Its blower has a two-speed
control switch on the instrument
panel.
Four Season Air Conditioning System
Operating instructions for your
Four Season Air Conditioner are
as follows:
Fan
The fan lever has four (4) posi-
30
tions from Lo at the bottom to Hi
at the top. When the air condition­
ing system
is off, low blower will
be maintained (after engine cool­
ant temperature has reached
85°P.)

Downloaded from www.Manualslib.com manuals search engine no matter which position the fan
switch
is in.
Temperature (Lower Level)
The temperature lever allows a
selection of air temperature from
Cold at the far left to Hot at the
far right. When the temperature
lever
is in the COLD position the
system will provide the coldest air
possible. When the temperature
lever
is moved to the right (toward
HOT), the system will operate on
outside air.
Selector (Upper Lever)
This lever provides a selection of
systems available to handle various
heating and cooling requirements
throughout the year. The Selector
lever has four
(4) major opera- tiona!
positions-"Off,"
"Air Con­
ditioning," "Vent" and "Heating."
The "Air Conditioning" and "Heat­
ing"
groups have several positions
which improve the effectiveness of
the system for various demands.
OFF-The system. operates on low
blower regardless of fan switch
position with air discharged into
vehicle through heater outlet.
A/C-Air from the passenger com­
partment is recirculated through
the system with some outside air
and discharged from the upper
outlets when the temperature lever
is in Full COLD or extreme left. If
the Temperature lever is moved
right to the first stop or further,
the system will automatically go
on outside air. The
AIC position,
with Temp. lever in Full
COLD,
31
is used when maximum cooling is
required under conditions of high
temperature and humidity. High
fan speed
is automatically attained
in this position.
A/C(with Temp lever right to first
stop
)-Outside air is passed through
the system and discharged through
the upper outlets. This position
is
recommended for most air condi­
tioning situations because of
re­
duced blower noise and reduction
of cigarette smoke within the
vehicle.
Fan speed may be varied
as required.
VENT -Outside air is passed
through the system and discharged
from the upper and lower outlets.
This position
is provided for cool
to moderate weather when refrig­
eration
is not required.

Downloaded from www.Manualslib.com manuals search engine type cooling system is used on all
1973 Camaro air conditioned and
heavy duty cooling systems. It has
been filled at the factory with a
high-quality, inhibited, year-around
coolant that meets the standards
of General Motors Specification
1899-M. This coolant solution pro­
vides freezing protection to
-20 0 F
(-32°F in Canada), and it has
been formulated to be used for
two full calendar years
or 24,000
miles, whichever first occurs, of
normal operation without draining,
provided the proper concentration
of coolant
is maintained.
• For Recovery Systems Only­
Check the coolant level visually
at the see-through coolant reser­
voir at each oil change interval
while the engine
is at normal
operating temperature. Do not
remove radiator cap except for
draining and refilling the system.
Coolant level should be at the
"Full Hot" mark on the reservoir.
If system is checked cold, the
coolant level should be at the
"Full Cold" mark on the reser­
voir.
• For Other Than Recovery Sys­
tems-Check the coolant level
only at oil change intervals, un­
less there
is evidence of leaking
or overheating. Do not remove
radiator cap when solution
is
hot and under pressure. Coolant
level should be a maximum of
three inches below the level of
the filler neck when the engine
is cold.
• All Systems-Add a 50/50 mix­
ture of high-quality ethylene
glycol antifreeze and water if
coolant additions are necessary.
Do not overfill.
NOTE: If recommended quality
antifreeze
is used, supplemental
inhibitors or additives claiming to
53
provide increased cooling capabil­
ity are not necessary. They may be
detrimental to the efficient opera­
tion of the system, and represent
an unnecessary operating expense.
Every year, the cooling system
should be serviced
as follows:
1. Wash radiator cap and filler
neck with clean water.
2. Check coolant for proper level
and freeze protection.
3. Pressure test system and radia­
tor cap for proper pressure hold­
ing capacity (15 psi).
If re­
placement
of cap is required,
use the proper AC cap specified
for your car model.
4. Tighten hose clamps and inspect
all hoses. Replace hoses when­
ever checked, swollen
or other­
wise deteriorated.
5. Clean frontal area of radiator
core and air conditioning con­
denser.
