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."

Braking System
The service brake system is de­
signed for braking performance
under a wide range of driving con­
ditions even when the vehicle
is
loaded to its full rated vehicle load.
Power Brakes
• On cars with power brakes if
power assist to the brakes
is
interrupted due to a stalled en­
gine
or some malfunction, two
or more brake applications can
be made using reverse power.
• If the brake pedal is held down ,
the system
is designed to bring
the car to a full stop on reserve
power. However, the reserve
power
is partially depleted each
time the brake pedal
is applied
and released.
• When reserve power is ex- hausted,
the vehicle can still be
stopped by applying greater
force to the pedal.
Parking Brake
• To set parking brake, fully de­
press foot pedal at far left side.
• For maximum holding power,
depress regular brake pedal with
the other foot at the same time.
• To release parking brake, pull
"BRAKE RELEASE" lever on
lower left instrument panel.
• As a reminder, the brake system
warning light
is designed to glow
whenever the parking brake con­
trol
is not fully released, and the
ignition
is on.
• Never drive car with parking
brake set
as this may overheat
or otherwise damage rear brakes.
23
Clutch Adjustment
Clut8h adjustment should be
checked and adjusted periodically
as necessary to compensate for
clutch facing wear.
To check, de­
press pedal by hand until resist­
ance
is felt. Free travel of pedal
should be approximately one inch;
if very little
or no free travel is
evident, clutch adjustment is re­
quired.

Downloaded from www.Manualslib.com manuals search engine Generator Indicator Light
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.
27
• 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 • Maintain cooling system freeze
protection at
.;...200 F or below
to ensure protection against
corrosion and loss of coolant
from boiling , even though freez­
ing temperatures are not
ex­
pected.
• Add ethylene glycol base cool­
ant that meets GM Specification
1899-M when coolant additions
are required because of coolant
loss or to provide additional
protection against freezing at
temperatures lower than
_200 F
(_320 F in Canada).
NOTE: Alcohol or methanol base
coolants or plain water are not
recommended for your Monte
Carlo at any time.
Radiator Pressure Cap
The radiator cap, a 15 lb. pres­
sure type, must be installed tightly,
otherwise coolant may be lost and
damage to engine may result from
overheating. Radiator pressure caps
should be checked periodically for
proper operation.
If replacement is
required specify AC.
Thermostat
The cooling system is protected
and controlled by a thermostat in­
stalled in the engine coolant outlet
to maintain a satisfactory operating
temperature of the engine. This
thermostat
is designed for continu­
ous use through both winter and
summer and need not be changed
seasonally . When replacement
is
necessary, Delco parts are recom­
mended.
60
Tires
The factory installed tires on
your car
as shown on the following
Tire Usage chart are designed to
provide the best all around per­
formance for normal vehicle op­
eration. When inflated
as recom­
mended on the tire pressure plac­
ard, located on the left door of
your vehicle, they have the load
carrying capacity to operate satis­
factorily at all normal highway
speeds.
Tire Care
Tires should be checked regu­
larly for proper inflation pressure,
wear, and damage. The following
information will assist you in prop­
erly caring for your tires:

Downloaded from www.Manualslib.com manuals search engine a bobby pin) between the rubber
cup
at the end of the spark plug
wire
and the tubular metal con­
nector inside
of it. If the spark plug wire is wet or oily, wipe it
dry.
Wrap a dry handkerchief or
facial tissue, folded several thick­
nesses,
around the wire at least
three inches back from the end and grasp the wire at this point.
Hold the bare wire about V4 inch
from the
bore tip of the spark plug from which you removed the Checking Spark
wire. When the engine is "turned over" a spark should jump across
the 1,4 inch space, indicating ample current supply. If no spark
jumps, the difficulty is probably caused by a defective ignition part
and should be corrected by your Authorized Chevrolet Dealer.
COOLING SYSTEM
When the car will run but evidences serious overheating on the
temperature gauge in the instrument panel, there are several items
which may
be checked.
IL) Engine overheating will occur when the OIL LEVEL falls danger­
ously low. Check the oil level as a mailer of course.
1M) Low COOLANT LEVEL will, of course, cause engine over­
heating . Determine the
cause of the low coolant level and have it corrected if necessary.
70
IN) Check the RADIATOR CORE. Clean it if it is plugged with
bugs, leaves or other foreign material.
(0) Condition of the FAN BELT
is very important, not only for en­
gine cooling but
also for proper
generator operation. Check the
condition of the belt. Replace it
if it is worn or frayed. Loosen
the generator toward the engine
to remove
and replace the belt.
Tighten the belt, whether new or
old, by loosening the generator
bolts, prying with a bar on the
generator until the belt is ten­
sioned properly , then retighten
the
generator bolts.
(P) Another couse of engine
overheating may be
an inopera­
tive
COOLING SYSTEM THER­
MOSTAT. If the thermostat should
foil in the dosed position, it will
not permit
coolant to circulate
through the system. In such an
emergency the thermostat may be
removed but should be
replaced with a properly functioning ther­
mostat as soon as possible.
