Engine Exhaust Gas Caution (Carbon Monoxide)
AvoId Inhaling exhaust gases because
they contaIn carbon monoxide, which by
Itselt is colorless and odorless. Carbon
monoxide Is a dangerous gas that can
cause unconsciousness and is potentially
lethal.
If at any time you suspect that exhaust
fumes are entering the passenger com­partment, have the cause determined and
corrected as soon as possible. If 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 sys­tem, car body and body ventilatIon system, It Is recommended that the exhaust system
and body be Inspected by a competent
mechanIc.
• Each time the vehIcle Is raised for an 011 change.
• Whenever 8 change Is noticed In the
sound Of the exhaust system.
• Whenever the exhaust system, under­body 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 aIr Inlet grille
forward of windshield and rear ventilation
grille on station wagon quarter. panels
clear ot snow or other
obstruction at all times, and prevent cargo from blocking
the inside vent holes on the underside of the quarter panels.
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:
2-1
1. On cars not equipped with air con­ditioning, set fan to medium or high
speed and upper control lever to any
position except OFF.
2. On cars equipped with air conditIon­ing, set fan 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 for long
durations with the trunk lid open. However, it tor some reason the trunk must remain
open for a period while moving, or elec­trical wiring or other cable connections to
a trailer must pass through the seal be­
tween trunk
lid and body, the following
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 fan set
at hIgh speed.
• On cars equIpped with outside aIr vents In or under Instrument panel, open vents
fully.

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
2-12).
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.
Clock
Reset the clock, if your car is so
equipped, by pulling out the knob
and turning the hands clockwise if

slow, counterclockwise if fast. This
will,
if the clock error is five min­
utes
or more, automatically com­
pensate for time gain or lag. Several
resettings, several days apart, may
be needed to properly adjust the
clock mechanism. Have your clock
cleaned and oiled by a competent
clock serviceman at least every two
years.

Cigarette Lighter
The cigarette lighter is located
on the instrument panel
face. To
operate . push it in. When it be­
comes
Heated, it automatically pops
out ready for use.
Optional Instruments and
Gauges
Tachometer
The optional Tachometer indi­
cates the speed of the engine in
revolutions
per minute.
Engine Temperature Gauge
This optional gauge indicates
coolant temperature which will vary
with air temperature and operat­
ing conditions.
The ignition switch
must be on for accurate readings.
Hard driving
or prolonged idling in
very hot weather will cause the
pointer to move beyond the center
of the band. Should pointer move
to the line at the right end of the
band, stop engine or reduce speed
to permit engine to cool.

FUSES AND CIRCUIT BREAKERS
The wiring circuits in your Vega are protected trom short
circuits by a combination of fuses, circuit breakers, and fusible
6-3
thermal links In the wiring Itself. This greatly reduces the hazard
of electrically caused fires in the automobile.

Downloaded from www.Manualslib.com manuals search engine FUSES AND CIRCUIT BREAKER:
The headlamp circuits are protected by a circuit breaker in the
light switch . An -electrical overload 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.

An Air Conditioning high blower 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.
