Engine Exhaust Gas Caution (Carbon Monoxide)
Allold inhaling exhaust gases because
they contain carbon monoxide, which by
Itsell is colorless and odorless. Carbon
monoxide is a dangerous gas that can cause unconsciousness and is potentially
lethal.
II at any time you suspect that exhaust fumes are entering the passenger com­partment, have the cause determined and corrected as soon as possible. II 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 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 IIehicie is raised for oil change. > •
Wheneller a change
is noticed In the
sound of the exhaust system.
• Wheneller 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
IIentilation 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 mOlle IIehicle In or out of area. When IIe­hlcle 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:
14
1. On cars not equipped with air condi­
tioning, set fan to medium or high
speed and upper control leller to any
position except OFF.
2. On cars equipped with manual air conditioning, set fan to medium or high speed, upper control lever to any
position except OFF, and lower con­trol lever to any position except ex­treme left COLD.
The trunk lid should be closed while
drilling to help prellent inadllertently draw­Ing exhaust gases Into the car. If Is unwise to drive at high speeds for long durations
with the trunk lid open. Howeller, If lor some reason the trunk must remain open lor a period while mOiling, or electrical wiring or other cable connections to a trailer must pass through the seal between
trunk lid and body, the lol/owlng precau­
tions should be observed:
• Close all windows.
• Ad/ust heating or cooling system to
force outside air into car as described In items 1 and 2 abolle but with Ian set at high speed.
• On cars equipped with outside aIr IIents In or under Instrument panel, open IIents lully.

If control button is not fully de­
pressed, when changing speed
setting,
. the car will resume your
previously selected speed.
To disengage system, lightly de­
press brake pedal or fully de­
press the control button.
Horn
The hom on your Monte Carlo
is actuated · by firmly pressing on
the pad in the center of the steering
wheel. 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
your car, should it ever become
necessary to give a warning to a
pedestrian
or another motorist.
Holding Car on an Upgrade
When stopped on an upgrade,
maintain your position by apply­
ing the brakes. Never hold the
car in place by accelerating en-gine
with transmission in gear.
This could cause damage by over­
heating the transmission (auto­
matic)
or clutch (manual).
Parking Your Car
Always engage the parking
brake and place the automatic
transmission selector lever in
"Park" position when leaving your
car unattended. Also with auto­
matic transmissions, never park
for prolonged periods with engine
idling and transmission in gear,
especially if your car
is equipped
with air conditioning. This prac­
tice
is detrimental to the trans­
mission, due to overheating.
NOTE: For operation of hazard flasher, see page 41, in Section "In Case of Emergency."

This light provides a quick
check on the generating system
of your car. The red light will
go on when the ignition key
is
in the "on" position, 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 run­
ning , have your Authorized Chev­
rolet 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
overheating
is corrected. Glance
at instrument cluster frequently
as
you drive to see if this light is on.
Brake System Warning Light
The service brake system is
designed so that half of the brake
system will provide some braking
action in the event of a hydraulic
leak in the other half of the
sys­
tem. If the warning light located
below the fuel gauge glows con­
tinuously when the ignition
is on
and after the brakes have been
firmly applied, it may indicate that
there
is a malfunction in one half
of the brake hydraulic system.

• As a check on bulb condition
the light should glow with the
parking brake applied and the
ignition on. (Light
is also a
reminder 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
partially inoperative
What to do:
1. Check that the parking brake
is released. If it is ...
2. Pull off the road and stop,
carefully- remembering that:

Downloaded from www.Manualslib.com manuals search engine • Stopping distances may be
greater.
• Greater pedal effort may be
required .
• Pedal travel may be greater.
3.
Tryout braking operation by
starting and stopping on road
shoulder -then:
• If you judge such operation
to be safe , proceed cautious
ly
at a s afe 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
ybu
with proper night-time visibility
for most driving conditons . 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 24).
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.

frequently move beyond the center
of the band.

CONTROLS
using washer -to help prevent
icing that may seriously obscure
vision.
Air Vents
The air vents under the instru­
ment panel admit air from the vent
grille just ahead of the windshield.
A push-pull control opens and
closes the vents.
The amount of air entering the
car through this system
is depend­
ent upon vehicle speed.
The vent lever controls under the
instrument panel control the
air
flow through the instrument
panel center outlets (upper) and
outlets under the instrument panel.
NOTE: See engine exhaust gas
caution at the beginning of this
section.
Ventilation System
Your Monte Carlo incorporates
a ventilation system that pro­
vides improved ventilation com-
32
fort, made possible by the addition
of air vent provisions in the rear
body lock pillar. Another feature
of the system
is continuous low­
speed operation of the heater and
air conditioner blower, resulting
in
an uninterrupted supply of outside
air
flow into the car whenever the
ignition switch
is on.
Wth the side windows closed,
outside air will
flow into the front
grilles, through the car and out the
rear air exhaust valves.
