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.

greater.
• Greater pedal effort may be re­
quired .
• Pedal travel may be greater.
3.
Tryout brake operation by
starting and stopping on road
shoulder-then:
• If you judge such operation to
be safe, proceed cautiously at a
safe speed to nearest dealer for
repair.
• Or have car towed to dealer for
repair.
Continued operation of the car
in this condition
is dangerous.
Headlight Beam Indicator
Light
The headlights of your car have
high and low
beams to provide you with
proper night-time visibility
for most driving conditions. The
"low" beams are used during most
city driving. The
"high" beams are
especially useful when driving on
dark roads since
they' provide ex­
cellent long range illumination.
The headlight beam indicator will
be on whenever the high beams
or
"brights" are in use. The Headlight
Beam Switch controls the headlight
beams (see Page
21).
Light Switch
The three position light switch
controls the headlights, taillights,
parking lights, side marker lights,
instrument lights and dome lights
as shown. The headlamp circuit is
protected by a circuit breaker in the
light switch.
An overload on the
breaker will cause the lamps to
"flicker" on and off. If this condi­
tion develops, have your headlamp
wiring checked immediately.

you can suspect a faulty IDLE ADJUSTMENT, a malfunctioning AUTOMATIC CHOKE or an extremely dirty and blocked AIR CLEANER ELEMENT. Replace paper element air cleaner if neces­sary. Idle adjustment or automatic choke service (other than that outlined in paragraph 0 above) should be performed by your
Chevrolet Dealer.
If the above Fuel System checks and the checks suggested under the Electrical System following do not correct the malfunction, it is recommended that you return to your Authorized Chevrolet Dealer
for further checks, adjustments or repairs.
ELECTRICAL SYSTEM If, when the ignition key is turned to "Start", the engine will not
turn over, you have good reason to suspect electrical trouble. NOTE: Never remove Delcotron bat lead without first disconnecting
battery ground cable.
IF) When there is no response at all to attempts to start the car, check the obvious-your AUTOMATIC TRANSMISSION SELECTOR LEVER must be in Neutral or Park position (manual transmission
must have clutch depressed all the way to floor) before the engine can be started. Turning the IGNITION SWITCH rapidly back and forth several times will sometimes correct a poor internal switch
contact.
IG) The BATIERY may be discharged. If so, lights will be dim and the horn will have a poor tone if it will blow at all.
Usually a garage recharge will be necessary to return the battery to operation. Occasionally, however, a long drive will recharge the battery. NOTE: If the battery is determined to be dead, and for no apparent reason, have your Authorized Chevrolet Dealer check the
battery, the GENERATOR and the VOLTAGE REGULATOR.
GENERATOR trouble should already have been indicated by the generator indicator light on the instrument panel.
64
POOR BATIERY CONNECTIONS may be suspected if the car has operated properly a short time before and now not even the horn
will operate. Check both ends of both battery cables. If the con­nections are corroded, a car may sometimes be restored to opera­tion by removing all cable ends, scraping all contacting surfaces
clean with a pen knife, and reassembling. If the cables are broken,
they must be replaced. The power supply should now be restored
unless the battery is dead.
IH) If, however, the lights and horn work properly but the starter will still not turn over, check the STARTER connections. A "click" from the starter solenoid indicates that the wiring to the starter is properly installed. If the wiring seems to be clean and tightly in­
stalled, the trouble is probably in the starter itself and should be referred to your Authorized Chevrolet Dealer.
When the engine will
"turn over" but will not start, the foilowing
items may be checked along with the Fuel Systems Checks listed
previously.
II) With a clean dry cloth, wipe the ceramic portions of the spark plugs dry. In particularly damp or rainy weather dampness may be
the cause of not sta rting, especi­
ally when the engine is cold.
IJ) Check the cables at the top of the distributor and coil as well as each spark plug cable for
tightness.
IK) If the co r will still not sta rt,
check for spark at the spark plugs in the following manner:
Pull one of the spark plug
wires off its spark plug. Insert a
short piece of bare wire (such as Di.,ribu'or and Coil Cab I ••

FUSES AND CIRCUIT BREAKERS
The wiring circuits in your 1973 Camaro
are protected from short circuits by a
combin­
ation of fuses , circuit breakers , and fusible
thermal links in the wiring itself. This greatly
reduces the hazard of electrically caused
fires
in the automobile. The fuse junction block is
located under the left side of the instrument
panel.

Downloaded from www.Manualslib.com manuals search engine FUSES AND CIRCUIT BREAKER:
The headlamp circuit is protected by a circuit breaker in the light switch. An electrical overload on the breaker will cause the lamps to go on and off, or in some cases to remain off. If this condition develops, have your wiring circuits checked immediately. Where current load is too heavy, the circuit breaker intermittently opens and closes, protecting the circuit until the cause is found and eliminated.
Fuses, located in the Junction Block beneath the dash on the driver's side are:

An Air Conditioning high blower speed fuse,30 amp. is located in an In·line fuse holder running from horn relay to Air Conditioning relay.
Do not use fuses of higher amperage rating than those recommended above.
Fusible links are incorporated into the wiring system. These are wires of such a gauge that they will fuse (or melt) before damage occurs to an entire wiring harness in the event of an electrical overload. See your Chevrolet Dealer if fusible link replacement becomes necessary.
